    Luiz Eduardo Imbelloni

    Full Text Available CONTEXT AND OBJECTIVES: In major orthopedic surgery of the lower limbs, continuous spinal anesthesia (CSA and combined spinal epidural anesthesia (CSE are safe and reliable anesthesia methods. In this prospective randomized clinical study, the blockading properties and side effects of CSA were compared with single interspace CSE, among patients scheduled for major hip or knee surgery. DESIGN AND SETTING: Prospective clinical study conducted at the Institute for Regional Anesthesia, Hospital de Base, São José do Rio Preto. METHODS: 240 patients scheduled for hip arthroplasty, knee arthroplasty or femoral fracture treatment were randomly assigned to receive either CSA or CSE. Blockades were performed in the lateral position at the L3-L4 interspace. Puncture success, technical difficulties, paresthesia, highest level of sensory and motor blockade, need for complementary doses of local anesthetic, degree of technical difficulties, cardiocirculatory changes and postdural puncture headache (PDPH were recorded. At the end of the surgery, the catheter was removed and cerebrospinal fluid leakage was evaluated. RESULTS: Seven patients were excluded (three CSA and four CSE. There was significantly lower incidence of paresthesia in the CSE group. The resultant sensory blockade level was significantly higher with CSE. Complete motor blockade occurred in 110 CSA patients and in 109 CSE patients. Arterial hypotension was observed significantly more often in the CSE group. PDPH was observed in two patients of each group. CONCLUSION: Our results suggest that both CSA and CSE provided good surgical conditions with low incidence of complications. The sensory blockade level and hemodynamic changes were lower with CSA.

    Full Text Available Sexual and reproductive health is important quality of life outcomes, which can have a major impact on patient satisfaction. Spinal pathology arising from trauma, deformity, and degenerative disease processes may be detrimental to sexual and reproductive function. Furthermore, spine surgery may impact sexual and reproductive function due to post-surgical mechanical, neurologic, and psychological factors. The aim of this paper is to provide a concise evidence-based review on the impact that spine surgery and pathology can have on sexual and reproductive function. A review of published literature regarding sexual and reproductive function in spinal injury and spinal surgery patients was performed. We have found that sexual and reproductive dysfunction can occur due to numerous etiological factors associated with spinal pathology. Numerous treatment options are available for those patients, depending on the degree of dysfunction. Spine surgeons and non-operative healthcare providers should be aware of the issues surrounding sexual and reproductive function as related to spine pathology and spine surgery. It is important for spine surgeons to educate their patients on the operative risks that spine surgery encompasses with regard to sexual dysfunction, although current data examining these topics largely consists of level IV data.

    To evaluate the incidence of venous thromboembolism in spine surgery with no chemical and mechanical prophylaxis, and to determine the specific risk factors for this complication. A historical cohort was analysed. All patients subjected to major spinal surgery, between January 2010 and September 2014, were included. No chemical or mechanical prophylaxis was administered in any patient. Active mobilisation of lower limbs was indicated immediately after surgery, and early ambulation started in the first 24-48 hours after surgery. Clinically symptomatic cases were confirmed by Doppler ultrasound of the lower limbs or chest CT angiography. A sample of 1092 cases was studied. Thromboembolic events were observed in 6 cases (.54%); 3 cases (.27%) with deep venous thrombosis and 3 cases (.27%) with pulmonary thromboembolism. A lethal case was identified (.09%). There were no cases of major bleeding or epidural haematoma. The following risk factors were identified: a multilevel fusion at more than 4 levels, surgeries longer than 130 minutes, patients older than 70 years of age, hypertension, and degenerative scoliosis. There is little scientific evidence on the prevention of thromboembolic events in spinal surgery. In addition to the disparity of prophylactic methods indicated by different specialists, it is important to weigh the risk-benefit of intra- and post-operative bleeding, and even the appearance of an epidural haematoma. Prophylaxis should be assessed in elderly patients over 70 years old, who are subjected to surgeries longer than 130 minutes, when 4 or more levels are involved. Copyright © 2015 SECOT.

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

    This study aimed to assess driving reaction times (DRTs) after spinal surgery to establish a timeframe for safe resumption of driving by the patient postoperatively. The MEDLINE and Google Scholar databases were analyzed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) Statement for clinical studies that investigated changes in DRTs following cervical and lumbar spinal surgery. Changes in DRTs and patients' clinical presentation, pathology, anatomical level affected, number of spinal levels involved, type of intervention, pain level, and driving skills were assessed. The literature search identified 12 studies that investigated postoperative DRTs. Six studies met the inclusion criteria; five studies assessed changes in DRT after lumbar spine surgery and two studies after cervical spina surgery. The spinal procedures were selective nerve root block, anterior cervical discectomy and fusion, and lumbar fusion and/ordecompression. DRTs exhibited variable responses to spinal surgery and depended on the patients' clinical presentation, spinal level involved, and type of procedure performed. The evidence regarding the patients' ability to resume safe driving after spinal surgery is scarce. Normalization of DRT or a return of DRT to pre-spinal intervention level is a widely accepted indicator for safe driving, with variable levels of statistical significance owing to multiple confounding factors. Considerations of the type of spinal intervention, pain level, opioid consumption, and cognitive function should be factored in the assessment of a patient's ability to safely resume driving.

    With development of more tissue banks in the region and internationally, allografts are increasingly being used in orthopaedic surgery including spinal surgery. Two groups of patients will particularly benefit from the use of allografts. The first group is young children in whom iliac crest is cartilaginous and cannot provide sufficient quantity of autografts. The second is the elderly where bones from iliac crest are porotic and fatty. Allografts are used to fulfill two distinct functions in Spinal Surgery. One is to act as a buttress for anterior spinal surgery using cortical allografts. The other is to enhance fusion for posterior spinal surgery. Up to December 1997, 71 transplantations have been performed using allografts from NUH Tissue Bank. Anterior Spinal Surgery has been performed in 15 cases. The indications are mainly Trauma-Burst Fractures and Spinal Secondaries to the Spine. All cases are in thoracic and thoracolumbar region. Allografts used are deep frozen and freeze-dried cortical allografts. Femur is used for thoraco-lumbar region and humerus for upper thoracic region. Instrumentation used ranged from anterior devices (Canada, DCP, Synergy etc) to posterior devices (ISOLA). Deep frozen allografts and more recently freeze-dried allografts are preferred especially for osteoporotic spines. Cortical allografts are packed with autografts from ribs in the medullary canal. Allograft-autograft composites are always used to ensure better incorporation. Postero-lateral fusion has been performed for 56 cases. The indications include congenital and idiopathic scoliosis, degenerative stenosis, degenerative spondylolisthesis, spondylolytic spondylolisthesis, fracture-dislocation, osteoporotic burst fracture, spinal secondaries with cord compression and traumatic spondylolisthesis. Deep frozen bone allografts are used in combination with patient's own autografts from spinous processes to provide a 50% mix. Instrumentation used include Hartshill, Steffee, Isola

    Spinal deformity is a condition that has been recognized for many millennia. There have been major advances in the treatment of spinal deformity in recent years and studies outlining new ideas can inspire others to further advance the speciality. The number of citations a paper receives may indicate the influence of that paper. It is therefore important that we evaluate and analyze the most cited works in our field. The aim of this study is to identify the 100 most cited papers relevant to spinal deformity surgery in the literature. A search through the Thomson Reuters Web of Science™ for citations related to spinal deformity surgery was performed. The number of citations, mean citation number (total number citations/years since publication), journal, authors, year of publication and country of origin of the top 100 papers was recorded. The top 100 papers were cited a combined 17,646 times, ranging from 453 to 112. The majority of papers originated from the United States (71) and were published in 20 different journals. The decade 1990-1999 was the most prolific, with 36 of the 100 papers published during this time. Papers pertaining to the management of scoliosis (49) were the most common. This study identifies the top 100 most cited papers in the field of spinal deformity surgery. While citation is not a specific marker of the scientific quality of a paper, it is a surrogate for the influence a paper has had on the orthopedic community. This list of papers provides an invaluable resource for both those in training and those actively practicing and involved in the further development of spinal deformity surgery.

    The increased utilization of smartphones together with their downloadable applications (apps) provides opportunity for doctors, including spinal surgeons, to integrate such technology into clinical practice. However, the clinical reliability of the medical app sector remains questionable. We reviewed available apps themed specifically towards spinal surgery and related conditions and assessed the level of medical professional involvement in their design and content. The most popular smartphone app stores (Android, Apple, Blackberry, Windows, Samsung, Nokia) were searched for spinal surgery-themed apps, using the disease terms Spinal Surgery, Back Surgery, Spine, Disc Prolapse, Sciatica, Radiculopathy, Spinal Stenosis, Scoliosis, Spinal Fracture and Spondylolisthesis. A total of 78 individual spinal surgery themed apps were identified, of which there were six duplicates (N = 72). According to app store classifications, there were 57 (79 %) medical themed apps, 11 (15 %) health and fitness themed apps, 1 (1 %) business and 3 (4 %) education themed apps. Forty-five (63 %) apps were available for download free of charge. For those that charged access, the prices ranged from £0.62 to £47.99. Only 44 % of spinal surgery apps had customer satisfaction ratings and 56 % had named medical professional involvement in their development or content. This is the first study to specifically address the characteristics of apps related to spinal surgery. We found that nearly half of spinal surgery apps had no named medical professional involvement, raising concerns over app content and evidence base for their use. We recommend increased regulation of spinal surgical apps to improve the accountability of app content.

    Retrospective cohort study of prospectively collected data. To examine the incidence of iatrogenic spinal cord injury following elective cervical spine surgery. A retrospective multicenter case series study involving 21 high-volume surgical centers from the AOSpine North America Clinical Research Network was conducted. Medical records for 17 625 patients who received cervical spine surgery (levels from C2 to C7) between January 1, 2005, and December 31, 2011, were reviewed to identify occurrence of iatrogenic spinal cord injury. In total, 3 cases of iatrogenic spinal cord injury following cervical spine surgery were identified. Institutional incidence rates ranged from 0.0% to 0.24%. Of the 3 patients with quadriplegia, one underwent anterior-only surgery with 2-level cervical corpectomy, one underwent anterior surgery with corpectomy in addition to posterior surgery, and one underwent posterior decompression and fusion surgery alone. One patient had complete neurologic recovery, one partially recovered, and one did not recover motor function. Iatrogenic spinal cord injury following cervical spine surgery is a rare and devastating adverse event. No standard protocol exists that can guarantee prevention of this complication, and there is a lack of consensus regarding evaluation and treatment when it does occur. Emergent imaging with magnetic resonance imaging or computed tomography myelography to evaluate for compressive etiology or malpositioned instrumentation and avoidance of hypotension should be performed in cases of intraoperative and postoperative spinal cord injury.

    Full Text Available Abstract Introduction Postoperative spinal extradural hematomas are rare. Most of the cases that have been reported occured within 3 days of surgery. Their occurrence in a delayed form, that is, more than 72 hours after surgery, is very rare. This case is being reported to enhance awareness of delayed postoperative spinal extradural hematomas. Case presentation We report a case of acute onset dorsal spinal extradural hematoma from a paraspinal muscular arterial bleed, producing paraplegia 72 hours following surgery for excision of a spinal cord tumor at T8 level. The triggering mechanism was an episode of violent twisting movement by the patient. Fresh blood in the postoperative drain tube provided suspicion of this complication. Emergency evacuation of the clot helped in regaining normal motor and sensory function. The need to avoid straining of the paraspinal muscles in the postoperative period is emphasized. Conclusion Most cases of postoperative spinal extradural hematomas occur as a result of venous bleeding. However, an arterial source of bleeding from paraspinal muscular branches causing extradural hematoma and subsequent neurological deficit is underreported. Undue straining of paraspinal muscles in the postoperative period after major spinal surgery should be avoided for at least a few days.

    A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can't tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than

    Minimally invasive surgery (MIS) is an alternative to open deformity surgery for the treatment of patients with adult spinal deformity. However, at this time MIS techniques are not as versatile as open deformity techniques, and MIS techniques have been reported to result in suboptimal sagittal plane correction or pseudarthrosis when used for severe deformities. The minimally invasive spinal deformity surgery (MISDEF) algorithm was created to provide a framework for rational decision making for surgeons who are considering MIS versus open spine surgery. A team of experienced spinal deformity surgeons developed the MISDEF algorithm that incorporates a patient's preoperative radiographic parameters and leads to one of 3 general plans ranging from MIS direct or indirect decompression to open deformity surgery with osteotomies. The authors surveyed fellowship-trained spine surgeons experienced with spinal deformity surgery to validate the algorithm using a set of 20 cases to establish interobserver reliability. They then resurveyed the same surgeons 2 months later with the same cases presented in a different sequence to establish intraobserver reliability. Responses were collected and tabulated. Fleiss' analysis was performed using MATLAB software. Over a 3-month period, 11 surgeons completed the surveys. Responses for MISDEF algorithm case review demonstrated an interobserver kappa of 0.58 for the first round of surveys and an interobserver kappa of 0.69 for the second round of surveys, consistent with substantial agreement. In at least 10 cases there was perfect agreement between the reviewing surgeons. The mean intraobserver kappa for the 2 surveys was 0.86 ± 0.15 (± SD) and ranged from 0.62 to 1. The use of the MISDEF algorithm provides consistent and straightforward guidance for surgeons who are considering either an MIS or an open approach for the treatment of patients with adult spinal deformity. The MISDEF algorithm was found to have substantial inter- and

    The aim of this study was to determine the changes in both the short and long term, in the trends within the practice of spinal surgery in Galway University Hospitals (GUH) over a seven year period, January 2005 – January 2013. The absolute number of spinal surgery cases has increased from 147 in 2005, to 257 cases by 2013. Multiple level spine surgery accounts for 51% (131) of all cases by 2013, which is an increase from 31% (45) in 2005. On analysis of the trends within spinal surgery during the study period, a statistically significant (p<0.05) increase in all aspects of spinal surgery was noted, with the exception of surgeries for single level, lumbar and infection pathology respectively. The average waiting time for lumbar decompression and instrumentation climbed for an average of 1.3 months in 2008 to 12.1 months by 2012.The volume and complexity of spinal surgery has increased during the study period, in the West of Ireland.

  17. Cervical spondylosis with spinal cord encroachment: should preventive surgery be recommended?

    2009-08-01

    Full Text Available Abstract Background It has been stated that individuals who have spondylotic encroachment on the cervical spinal cord without myelopathy are at increased risk of spinal cord injury if they experience minor trauma. Preventive decompression surgery has been recommended for these individuals. The purpose of this paper is to provide the non-surgical spine specialist with information upon which to base advice to patients. The evidence behind claims of increased risk is investigated as well as the evidence regarding the risk of decompression surgery. Methods A literature search was conducted on the risk of spinal cord injury in individuals with asymptomatic cord encroachment and the risk and benefit of preventive decompression surgery. Results Three studies on the risk of spinal cord injury in this population met the inclusion criteria. All reported increased risk. However, none were prospective cohort studies or case-control studies, so the designs did not allow firm conclusions to be drawn. A number of studies and reviews of the risks and benefits of decompression surgery in patients with cervical myelopathy were found, but no studies were found that addressed surgery in asymptomatic individuals thought to be at risk. The complications of decompression surgery range from transient hoarseness to spinal cord injury, with rates ranging from 0.3% to 60%. Conclusion There is insufficient evidence that individuals with spondylotic spinal cord encroachment are at increased risk of spinal cord injury from minor trauma. Prospective cohort or case-control studies are needed to assess this risk. There is no evidence that prophylactic decompression surgery is helpful in this patient population. Decompression surgery appears to be helpful in patients with cervical myelopathy, but the significant risks may outweigh the unknown benefit in asymptomatic individuals. Thus, broad recommendations for decompression surgery in suspected at-risk individuals cannot be made

    Retrospective multicenter case series. To assess the rate of perioperative vision loss following cervical spinal surgery. Medical records for 17 625 patients from 21 high-volume surgical centers from the AOSpine North America Clinical Research Network who received cervical spine surgery (levels from C2 to C7) between January 1, 2005, and December 31, 2011, inclusive, were reviewed to identify occurrences of vision loss following surgery. Of the 17 625 patients in the registry, there were 13 946 patients assessed for the complication of blindness. There were 9591 cases that involved only anterior surgical approaches; the remaining 4355 cases were posterior and/or circumferential fusions. There were no cases of blindness or vision loss in the postoperative period reported during the sampling period. Perioperative vision loss following cervical spinal surgery is exceedingly rare.

    Full Text Available ABSTRACT Objective: To identify the factors associated with postoperative infections in spinal surgery. Methods: Descriptive, retrospective, cross-sectional study conducted in the spine surgery department of the Medical Unit of High Specialty (UMAE at the Hospital of Traumatology and Orthopedics Lomas Verdes, Mexican Institute of Social Security (IMSS between January 01, 2013 and June 30, 2014 through medical records of the service and the records of clinical care. Data were gathered in accordance with the records of patients with infection after spinal surgery. The factors considered were age group, etiologic agent, surgical site, type of treatment, bleeding volume and pharmacotherapy. Frequency and descriptive statistic was conducted. The rank sum test with the Wilcoxon test for a single sample was performed in different measurements; Pearson's correlation was calculated and all p<0.05 values were considered significant. Results: The sample was composed of 14 patients of which 11 were female (78.6% and 3 male (21.4% with predominance of surgical area in the lumbar and dorsolumbar region. There was a significant correlation between the surgical time and the amount of bleeding with p<0.001. Conclusions: It was clear that the infections present in patients after spinal surgery are multifactorial. However, in this study the correlation between time of surgery and bleeding amount had the highest importance and relevance.

    Full Text Available Abstract Background Understanding the genetic basis of heritable spinal curvature would benefit medicine and aquaculture. Heritable spinal curvature among otherwise healthy children (i.e. Idiopathic Scoliosis and Scheuermann kyphosis accounts for more than 80% of all spinal curvatures and imposes a substantial healthcare cost through bracing, hospitalizations, surgery, and chronic back pain. In aquaculture, the prevalence of heritable spinal curvature can reach as high as 80% of a stock, and thus imposes a substantial cost through production losses. The genetic basis of heritable spinal curvature is unknown and so the objective of this work is to identify quantitative trait loci (QTL affecting heritable spinal curvature in the curveback guppy. Prior work with curveback has demonstrated phenotypic parallels to human idiopathic-type scoliosis, suggesting shared biological pathways for the deformity. Results A major effect QTL that acts in a recessive manner and accounts for curve susceptibility was detected in an initial mapping cross on LG 14. In a second cross, we confirmed this susceptibility locus and fine mapped it to a 5 cM region that explains 82.6% of the total phenotypic variance. Conclusions We identify a major QTL that controls susceptibility to curvature. This locus contains over 100 genes, including MTNR1B, a candidate gene for human idiopathic scoliosis. The identification of genes associated with heritable spinal curvature in the curveback guppy has the potential to elucidate the biological basis of spinal curvature among humans and economically important teleosts.

    The minimally invasive surgery in spinal surgery has become increasingly popular in recent years as it reduces the chances of complications during post-operation. However, the procedure of spinal surgery is complicated and the surgical vision of minimally invasive surgery is limited. In order to increase the quality of percutaneous pedicle screw placement, the O-arm that is a mobile intraoperative imaging system is used to assist surgery. The robot navigation system combined with O-arm is also increasing, with the extensive use of O-arm. One of the major problems in the surgical navigation system is to associate the patient space with the intra-operation image space. This study proposes a spatial registration method of spinal surgical robot navigation system, which uses the O-arm to scan a calibration phantom with metal calibration spheres. First, the metal artifacts were reduced in the CT slices and then the circles in the images based on the moments invariant could be identified. Further, the position of the calibration sphere in the image space was obtained. Moreover, the registration matrix is obtained based on the ICP algorithm. Finally, the position error is calculated to verify the feasibility and accuracy of the registration method.

    Three-dimensional printing (3DP), also known as "Additive Manufacturing", is a rapidly growing industry, particularly in the area of spinal surgery. Given the complex anatomy of the spine and delicate nature of surrounding structures, 3DP has the potential to aid surgical planning and procedural accuracy. We perform a systematic review of current literature on the applications of 3DP in spinal surgery. Six electronic databases were searched for original published studies reporting cases or outcomes for 3DP surgical models, guides or implants for spinal surgery. The findings of these studies were synthesized and summarized. These searches returned a combined 2,411 articles. Of these, 54 were included in this review. 3DP is currently used for surgical planning, intra-operative surgical guides, customised prostheses as well as "Off-the-Shelf" implants. The technology has the potential for enhanced implant properties, as well as decreased surgical time and better patient outcomes. The majority of the data thus far is from low-quality studies with inherent biases linked with the excitement of a new field. As the body of literature continues to expand, larger scale studies to evaluate advantages and disadvantages, and longer-term follow up will enhance our knowledge of the effect 3DP has in spinal surgery. In addition, issues such as financial impact, time to design and print, materials selection and bio-printing will evolve as this rapidly expanding field matures.

    Study Design Combination of narrative and systematic literature reviews. Objectives Massive perioperative blood loss in complex spinal surgery often requires blood transfusions and can negatively affect patient outcome. Systemic use of the antifibrinolytic agent tranexamic acid (TXA) has become widely used in the management of surgical bleeding. We review the clinical evidence for the use of intravenous TXA as a hemostatic agent in spinal surgery and discuss the emerging role for its complementary use as a topical agent to reduce perioperative blood loss from the surgical site. Through a systematic review of published and ongoing investigations on topical TXA for spinal surgery, we wish to make spine practitioners aware of this option and to suggest opportunities for further investigation in the field. Methods A narrative review of systemic TXA in spinal surgery and topical TXA in surgery was conducted. Furthermore, a systematic search (using PRISMA guidelines) of PubMed (MEDLINE), EMBASE, and Cochrane CENTRAL databases as well as World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov (National Institutes of Health), and International Standard Randomized Controlled Trial Number registries was conducted to identify both published literature and ongoing clinical trials on topical TXA in spinal surgery. Results Of 1,631 preliminary search results, 2 published studies were included in the systematic review. Out of 285 ongoing clinical trials matching the search criteria, a total of 4 relevant studies were included and reviewed. Conclusion Intravenous TXA is established as an efficacious hemostatic agent in spinal surgery. Use of topical TXA in surgery suggests similar hemostatic efficacy and potentially improved safety as compared with intravenous TXA. For spinal surgery, the literature on topical TXA is sparse but promising, warranting further clinical investigation and consideration as a clinical option in cases with

    To explore adolescents' memories about music therapy after spinal fusion surgery and their recommendations for future patients. Spinal fusion for adolescent idiopathic scoliosis is one of the most painful surgeries performed. Music therapy is shown to decrease postoperative pain in children after minor surgery. In preparation for developing a preoperative information program, we interviewed adolescents who had spinal fusion and postoperative music therapy to find out what they remembered and what they recommended for future patients. Eight adolescents who had spinal fusion for adolescent idiopathic scoliosis were interviewed about their experiences. For this qualitative study, the investigators independently used thematic analysis techniques to formulate interpretive themes. Together they discussed their ideas and assigned overall meanings to the information. The eight participants were 13-17 years of age and had surgery between 2-24 months previously. The overarching themes identified from the interviews were relaxation and pain perception, choice and control, therapist interaction and preoperative information. Participants stated that music therapy helped with mental relaxation and distraction from pain. It was important to be able to choose the type of music for the therapy and to use self-control to focus on the positive. Their recommendation was that future patients should be provided with information preoperatively about music therapy and pain management. Participants recommended a combination of auditory and visual information, especially the experiences of previous patients who had spinal fusion and music therapy. Music provided live at the bedside by a music therapist was remembered vividly and positively by most of the participants. The presence of a music therapist providing patient-selected music at the bedside is important. Methods to introduce adolescents to music therapy and how to use music for relaxation should be developed and tested. © 2012

    Full Text Available Objectives: As the population ages, the number of lumbar spinal surgeries performed on sarcopenic patients will increase. The purpose of this study was to investigate the prevalence of sarcopenia and evaluated its impact on the results of lumbar spinal surgery. Methods: This study included 2 groups: One group consisted of patients who underwent whole-body dual-energy X-ray absorptiometry (DXA scanning before the option of undergoing surgery for lumbar spinal disease (LSD group and a second group consisted of patients underwent DXA scanning for osteoporosis screening under hospital watch at the geriatric medicine department (control group. In order to evaluate the impact of sarcopenia on the clinical outcome of lumbar spinal surgery, the Japanese Orthopedic Association (JOA score, the recovery rate based on the JOA score, and visual analogue scale (VAS scores for lower back pain, lower extremity pain, and lower extremity numbness were compared within the LSD group. Results: The prevalence of sarcopenia showed no statistical difference between groups (control group, 50.7%; LSD group, 46.5%. In the LSD group, while the changes in VAS scores showed no statistical difference between the nonsarcopenia subgroup and sarcopenia subgroup, the sarcopenia subgroup demonstrated inferior JOA scores and recovery rates at the final follow-up when compared with the nonsarcopenia subgroup (P < 0.05. Conclusions: This study demonstrated a high prevalence of sarcopenia among the elderly populations in Japan and a negative impact of sarcopenia on clinical outcomes after lumbar spinal surgery.

    Spine surgery has experienced much technological innovation over the past several decades. The field has seen advancements in operative techniques, implants and biologics, and equipment such as computer-assisted navigation and surgical robotics. With the arrival of real-time image guidance and navigation capabilities along with the computing ability to process and reconstruct these data into an interactive three-dimensional spinal "map", so too have the applications of surgical robotic technology. While spinal robotics and navigation represent promising potential for improving modern spinal surgery, it remains paramount to demonstrate its superiority as compared to traditional techniques prior to assimilation of its use amongst surgeons.The applications for intraoperative navigation and image-guided robotics have expanded to surgical resection of spinal column and intradural tumors, revision procedures on arthrodesed spines, and deformity cases with distorted anatomy. Additionally, these platforms may mitigate much of the harmful radiation exposure in minimally invasive surgery to which the patient, surgeon, and ancillary operating room staff are subjected.Spine surgery relies upon meticulous fine motor skills to manipulate neural elements and a steady hand while doing so, often exploiting small working corridors utilizing exposures that minimize collateral damage. Additionally, the procedures may be long and arduous, predisposing the surgeon to both mental and physical fatigue. In light of these characteristics, spine surgery may actually be an ideal candidate for the integration of navigation and robotic-assisted procedures.With this paper, we aim to critically evaluate the current literature and explore the options available for intraoperative navigation and robotic-assisted spine surgery.

    The life-time incidence of low back pain is high and diagnoses of spinal stenosis and disc prolapse are increasing. Consequently, there is a steady rise in surgical interventions for these conditions. Current evidence suggests that while the success of surgery is incomplete, it is superior to conservative interventions. A recent survey indicates that there are large differences in the type and intensity of rehabilitation, if any, provided after spinal surgery as well as in the restrictions and advice given to patients in the post-operative period. This trial will test the hypothesis that functional outcome following two common spinal operations can be improved by a programme of post-operative rehabilitation that combines professional support and advice with graded active exercise and/or an educational booklet based on evidence-based messages and advice. The study design is a multi-centre, factorial, randomised controlled trial with patients stratified by surgeon and operative procedure. The trial will compare the effectiveness and cost-effectiveness of a rehabilitation programme and an education booklet for the postoperative management of patients undergoing discectomy or lateral nerve root decompression, each compared with "usual care"using a 2 x 2 factorial design. The trial will create 4 sub-groups; rehabilitation-only, booklet-only, rehabilitation-plus-booklet, and usual care only. The trial aims to recruit 344 patients, which equates to 86 patients in each of the four sub-groups. All patients will be assessed for functional ability (through the Oswestry Disability Index - a disease specific functional questionnaire), pain (using visual analogue scales), and satisfaction pre-operatively and then at 6 weeks, 3, 6 and 9 months and 1 year post-operatively. This will be complemented by a formal analysis of cost-effectiveness. This trial will determine whether the outcome of spinal surgery can be enhanced by either a post-operative rehabilitation programme or an

    The most common causes of pain following lumbar spinal fusions are residual herniation, or foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. The original surgeon may advise his patient that nothing more can be done in his opinion that the nerve was visually decompressed by the original surgery. Post-operative imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of failed lumbar spinal fusions by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain. The authors, having limited their practice to endoscopic surgery over the last 10 years, report on their experience gained during that period to relieve pain by transforaminal percutaneous endoscopic revision of lumbar spinal fusions. To assess the effectiveness of transforaminal percutaneous endoscopic discectomy and foraminoplasty in patients with pain after lumbar spinal fusion. Retrospective study. Inpatient surgery center. Sixteen consecutive patients with pain after lumbar spinal fusions presenting with back and leg pain that had supporting imaging diagnosis of foraminal stenosis and/or residual/recurrent disc herniation, or whose pain complaint was supported by relief from diagnostic and therapeutic injections, were offered percutaneous transforaminal endoscopic discectomy and foraminoplasty over a repeat open procedure. Each patient sought consultation following a transient successful, partially successful or unsuccessful open lumbar spinal fusions treatment for disc herniation or spinal stenosis. Endoscopic foraminoplasty was also performed to either decompress the bony foramen in the case of foraminal stenosis, or to allow for endoscopic visual examination of the affected traversing and exiting nerve roots in the axilla. The average follow-up time was 30.3 months, minimum 12 months. Outcome data at each visit

    Surgical navigation has been more actively deployed in open spinal surgeries due to the need for improved precision during procedures. This is increasingly difficult in minimally invasive surgeries due to the lack of visual cues caused by smaller exposure sites, and increases a surgeon's dependence on their knowledge of anatomical landmarks as well as the CT or MRI images. The use of augmented reality (AR) systems and registration technologies in spinal surgeries could allow for improvements to techniques by overlaying a 3D reconstruction of patient anatomy in the surgeon's field of view, creating a mixed reality visualization. The AR system will be capable of projecting the 3D reconstruction onto a field and preliminary object tracking on a phantom. Dimensional accuracy of the mixed media will also be quantified to account for distortions in tracking.

    Full Text Available Daniela Ghisi, Stefano Bonarelli Department of Anaesthesia and Postoperative Intensive Care, Istituto Ortopedico Rizzoli, Bologna, Italy Abstract: Spinal anesthesia is a reliable and safe technique for procedures of the lower extremities. Nevertheless, some of its characteristics may limit its use for ambulatory surgery, including delayed ambulation, risk of urinary retention, and pain after block regression. The current availability of short-acting local anesthetics has renewed interest for this technique also in the context of short- and ultra-short procedures. Chloroprocaine (CP is an amino-ester local anesthetic with a very short half-life. It was introduced and has been successfully used for spinal anesthesia since 1952. Sodium bisulfite was then added as a preservative after 1956. The drug was then abandoned in the 1980s for several reports of neurological deficits in patients receiving accidentally high doses of intrathecal CP during epidural labor analgesia. Animal studies have proven the safety of the preservative-free formulation, which has been extensively evaluated in volunteer studies as well as in clinical practice with a favorable profile in terms of both safety and efficacy. In comparison with bupivacaine, 2-chloroprocaine (2-CP showed faster offset times to end of anesthesia, unassisted ambulation, and discharge from hospital. These findings suggests that 2-CP may be a suitable alternative to low doses of long-acting local anesthetics in ambulatory surgery. Its safety profile also suggests that 2-CP could be a valid substitute for intrathecal short- and intermediate-acting local anesthetics, such as lidocaine and mepivacaine – often causes of transient neurological symptoms. In this context, literature suggests a dose ranging between 30 and 60 mg of 2-CP for procedures lasting 60 minutes or less, while 10 mg is considered the no-effect dose. The present review describes recent evidence about 2-CP as an anesthetic agent for

    Full Text Available Objective: Motor evoked potentials (MEPs changes might be caused to the non-surgically induced factors during cervical spinal surgery. Therefore, control MEPs recorded cranially to the exit of the C5 root are highly recommendable in cervical spinal surgery. We studied whether corticobulbar MEPs (C-MEPs from tongue muscle could be used as a control MEPs in cervical spinal surgery. Methods: Twenty-five consecutive cervical spinal surgeries were analyzed. Stimulation of motor area for tongue was done by subcutaneous electrodes placed at C3/C4 (10–20 EEG System, and recording was done from both sides of tongue. Results: C-MEPs were recorded successfully 24 out of the 25 (96% tested patients. Forty-six out of fifty MEPs (92% from tongue muscles were monitorable from the baseline. In two patients, we could obtain only unilateral C-MEPs. Mean MEPs latencies obtained from the left and right side of the tongue were 11.5 ± 1 ms and 11.5 ± 0.8 ms, respectively. Conclusions: Monitoring C-MEPs from tongue muscles might be useful control in cervical spinal surgery. They were easily elicited and relatively free from phenomenon of peripheral stimulation of the hypoglossal nerves. Significance: This is first study to identify the usefulness of C-MEPs as a control of cervical spinal surgery.

    Questions whether to continue or discontinue aspirin administration in the perioperative period of spinal surgery has not been systematically evaluated. The present systematic review is carried out to assess the impact of continuing aspirin administration on the bleeding and cardiovascular events in perispinal surgery period. Studies were retrieved through MEDLINE, EMBASE, and Springer Link Databases (search terms, aspirin, continue or discontinue, and spinal fusion), bibliographies of the articles retrieved, and the authors' reference files. We included studies that enrolled patients who underwent spinal surgery who were anticoagulated with aspirin alone and that reported bleeding or cardiovascular events as an outcome. Study quality was assessed using a validated form. 95% confidence interval (95% CI) was pooled to give summary estimates of bleeding and cardiovascular risk. We identified 4 studies assessing bleeding risk associated with aspirin continuation or cardiovascular risk with aspirin discontinuation during spinal surgery. The continuation of aspirin will not increase the risk of blood loss during the spinal surgery (95% CI, -111.72 to -0.59; P = .05). Also, there was no observed increase in the operative time (95% CI, -33.29 to -3.89; P = .01) and postoperative blood transfusion (95% CI, 0.00-0.27; P = .05). But as for the cardiovascular risk without aspirin continuation and mean hospital length of stay with aspirin continuation, we did not get enough samples to make an accurate decision about their relations with aspirin. Patients undergoing spinal surgery with continued aspirin administration do not have an increased risk for bleeding. In addition, there is no observed increase in the operation time and postoperative blood transfusion.

    Although recent trials provided level I evidence for the most common degenerative lumbar spinal disorders, treatment still varies widely. Thus, the Indications in Spinal Surgery (INDIANA) survey explores whether decision-making is influenced by specialty or personal emotional involvement of the treating specialist. Nationwide, neurosurgeons and orthopedic surgeons specialized in spine surgery were asked to answer an Internet-based questionnaire with typical clinical patient cases of lumbar disc herniation (DH), lumbar spinal stenosis (SS), and lumbar degenerative spondylolisthesis (SL). The surgeons were assigned to counsel a patient or a close relative, thus creating emotional involvement. This was achieved by randomly allocating the surgeons to a patient group (PG) and relative group (RG). We then compared neurosurgeons to orthopedic surgeons and the PG to the RG regarding treatment decision-making. One hundred twenty-two spine surgeons completed the questionnaire (response rate 78.7%). Regarding DH and SS, more conservative treatment among orthopedic surgeons was shown (DH: odds ratio [OR] 4.1, 95% confidence interval [CI] 1.7-9.7, p = 0.001; SS: OR 3.9, CI 1.8-8.2, p emotional involvement (PG vs. RG) did not affect these results for any of the three cases (DH: p = 0.213; SS: p = 0.097; SL: p = 0.924). The high response rate indicates how important the issues raised by this study actually are for dedicated spine surgeons. Moreover, there are considerable variations in decision-making for the most common degenerative lumbar spinal disorders, although there is high-quality data from large multicenter trials available. Emotional involvement, though, did not influence treatment recommendations.

Some studies have shown reduced surgical time, postoperative pain, time in the postanesthesia care unit (PACU, incidence of urinary retention, postoperative nausea, and more favorable cost-effectiveness with spinal anesthesia. Despite these results, the current literature has also shown contradictory results in between-group comparisons. Materials and methods: A retrospective analysis was performed by querying the electronic medical record database for surgeries performed by a single surgeon between 2007 and 2011 using procedural codes 63030 for diskectomy and 63047 for laminectomy: 544 lumbar laminectomy and diskectomy surgeries were identified, with 183 undergoing general anesthesia and 361 undergoing spinal anesthesia (SA. Linear and multivariate regression analyses were performed to identify differences in blood loss, operative time, time from entering the operating room (OR until incision, time from bandage placement to exiting the OR, total anesthesia time, PACU time, and total hospital stay. Secondary outcomes of interest included incidence of postoperative spinal hematoma and death, incidence of paraparesis, plegia, post-dural puncture headache, and paresthesia, among the SA patients.

    Intra-operative incidental contamination of surgical wounds is not rare. Povidone-iodine solution can be used to disinfect surgical wounds. Although povidone-iodine is a good broad-spectrum disinfecting agent, it has occasionally been reported to have a negative effect on wound healing and bone union. Therefore, its safety in a spinal surgery is unclear. A prospective, single-blinded, randomized study was accordingly conducted to evaluate the safety of povidone-iodine solution in spinal surgeries. Ascertained herein was the effect of wound irrigation with diluted povidone-iodine solution on wound healing, infection rate, fusion status and clinical outcome of spinal surgeries. From January 2002 to August 2003, 244 consecutive cases undergoing primary instrumented lumbosacral posterolateral fusion due to degenerative spinal disorder with segmental instability had been collected and randomly divided into two groups: the study group (120 cases, 212 fusion levels) and the control group (124 cases, 223 fusion levels). Excluded were those patients with a prior spinal surgery, spinal trauma, malignant tumor, infectious spondylitis, rheumatoid arthritis, ankylosing spondylitis, metabolic bone disease, skeletal immaturity or with an immunosuppressive treatment. In the former group, wounds were irrigated with 0.35% povidone-iodine solution followed by normal saline solution just before the bone-grafting and instrumentation procedure. However, only with normal saline solution in the latter. All the operations were done by the same surgeon with a standard technique. All the patients were treated in the same postoperative fashion as well. Later on, wound healing, infection rate, spinal bone fusion and clinical outcome were evaluated in both groups. A significant improvement of back and leg pain scores, modified Japanese Orthopedic Association function scores (JOA) and ambulatory capacity have been observed in both groups.

    Thoracic spinal anesthesia has been used for laparoscopic cholecystectomy and abdominal surgeries, but not in breast surgery. The present study compared this technique with general anesthesia in breast cancer surgeries. Forty patients were enrolled in this comparative study with inclusion criteria of ASA physical status I-III, primary breast cancer without known extension beyond the breast and axillary nodes, scheduled for unilateral mastectomy with axillary dissection. They were randomly divided into two groups. The thoracic spinal group (S) (n = 20) underwent segmental thoracic spinal anesthesia with bupivacaine and fentanyl at T5-T6 interspace, while the other group (n = 20) underwent general anesthesia (G). Intraoperative hemodynamic parameters, intraoperative complications, postoperative discharge time from post-anesthesia care unit (PACU), postoperative pain and analgesic consumption, postoperative adverse effects, and patient satisfaction with the anesthetic techniques were recorded. Intraoperative hypertension (20%) was more frequent in group (G), while hypotension and bradycardia (15%) were more frequent in the segmental thoracic spinal (S) group. Postoperative nausea (30%) and vomiting (40%) during PACU stay were more frequent in the (G) group. Postoperative discharge time from PACU was shorter in the (S) group (124 ± 38 min) than in the (G) group (212 ± 46 min). The quality of postoperative analgesia and analgesic consumption was better in the (S) group. Patient satisfaction was similar in both groups. Segmental thoracic spinal anesthesia has some advantages when compared with general anesthesia and can be considered as a sole anesthetic in breast cancer surgery with axillary lymph node clearance.

    Full Text Available Objective To estimate the effect of lorazepam in relieving postoperative wound pain and anxiety after spinal meningioma surgery. Methods A total of 106 patients underwent spinal meningioma resection with endotracheal general anesthesia. They were randomly divided into lorazepam group (N = 53 and control group (N = 53. Patients in lorazepam group were given lorazepam 0.50 mg one night before surgery and 6 h after surgery, while control group were given compound vitamin B at the same time. Operation time, intraoperative bleeding and wound healing after surgery were recorded. McCormick grade and Self-Rating Anxiety Scale (SAS were used to evaluate the spinal function and anxiety. At 48 h after surgery, Visual Analogue Scale (VAS was used to evaluate the degree of postoperative pain. Results All patients underwent tumor total resection, and spent the perioperative period safely. No complications such as infection happened. Neurological function were relieved to varying degrees and there was no worsening case. Compared with control group, SAS score in lorazepam group was significantly decreased at 48 h after surgery (P = 0.000. Compared with before surgery, SAS score in lorazepam group was significantly decreased at 48 h after surgery (P = 0.000.

    Prospective clinical study. To observe the usefulness of anterior cervical osteophytes as intrinsic markers for spinal level localization (SLL) during sub-axial cervical spinal surgery via the anterior approach. Various landmarks, such as the mandibular angle, hyoid bone, thyroid cartilage, first cricoid ring, and C6 carotid tubercle, are used for gross cervical SLL; however, none are used during cervical spinal surgery via the anterior approach. We present our preliminary assessment of SLL over anterior vertebral surfaces (i.e., intrinsic markers) in 48 consecutive cases of anterior cervical spinal surgeries for the disc-osteophyte complex (DOC) in degenerative diseases and granulation or tumor tissue associated with infectious or neoplastic diseases, respectively, at an ill-equipped center. This prospective study on patients undergoing anterior cervical surgery for various sub-axial cervical spinal pathologies aimed to evaluate the feasibility and accuracy of SLL via intraoperative palpation of disease-related morphological changes on anterior vertebral surfaces visible on preoperative midline sagittal T1/2-weighted magnetic resonance images. During a 3-year period, 48 patients (38 males,10 females; average age, 43.58 years) who underwent surgery via the anterior approach for various sub-axial cervical spinal pathologies, including degenerative disease (n= 42), tubercular infection (Pott's disease; n=3), traumatic prolapsed disc (n=2), and a metastatic lesion from thyroid carcinoma (n=1), comprised the study group. Intrinsic marker palpation yielded accurate SLL in 79% of patients (n=38). Among those with degenerative diseases (n=42), intrinsic marker palpation yielded accurate SLL in 76% of patients (n=32). Intrinsic marker palpation is an attractive potential adjunct for SLL during cervical spinal surgeries via the anterior approach in well-selected patients at ill-equipped centers (e.g., those found in developing countries). This technique may prove helpful

However, its intraoperative administration can lead to increased postoperative analgesic requirements, which is postulated to be the result of acute opioid tolerance with enhancement of spinal N-methyl-D-aspartate receptor function. Although strategies to prevent or reduce tolerance have included the coadministration of longer acting opioids or ketamine, the majority of these studies have demonstrated little to no benefit. The current study retrospectively evaluates the efficacy of intrathecal morphine (ITM in preventing hyperalgesia following a remifentanil infusion.Methods: We retrospectively analyzed 54 patients undergoing posterior spinal fusion with segmental spinal instrumentation, to evaluate the effects of ITM on hyperalgesia from remifentanil. Patients were divided into two groups based on whether they did or did not receive remifentanil during the surgery: no remifentanil (control group (n=27 and remifentanil (study group (n=27. Data included demographics, remifentanil dose and duration, Wong–Baker visual analog scale postoperative pain scores, and postoperative intravenous morphine consumption in the first 48 postoperative hours.Results: The demographics of the two study groups were similar. There were no differences in the Wong–Baker visual analog

    The purpose of this study was to investigate pedicle screw placement accuracy during navigated surgery by a junior spine surgeon who had no spinal surgery experience. A junior spine surgeon with no spinal surgery experience implanted a total of 137 pedicle screws by using a navigation system. Postoperative computerized tomography was performed to evaluate screw placement, and the pedicle perforation rate was 2.2%. There were no neurologic or vascular complications related to the pedicle screws. The results demonstrated that pedicle screws can be placed safely and effectively by a junior spine surgeon who has no spinal surgery experience when instructed by a senior spine surgeon. The results of this study suggest that navigation can be used as a surgical training tool for junior spine surgeons. (author)

    Recent advances in neuroimaging of the spine and spinal cord are described based upon our clinical experiences with spinal disorders. Preoperative neuroradiological examinations, including magnetic resonance (MR) imaging and computerized tomography (CT) with three-dimensional reconstruction (3D-CT), were retrospectively analyzed in patients with cervical spondylosis or ossification of the posterior longitudinal ligament (130 cases), spinal trauma (43 cases) and intramedullary spinal cord tumors (92 cases). CT scan and 3D-CT were useful in elucidating the spine pathology associated with degenerative and traumatic spine diseases. Visualization of the deformity of the spine or fracture-dislocation of the spinal column with 3D-CT helped to determine the correct surgical treatment. MR imaging was most important in the diagnosis of both spine and spinal cord abnormalities. The axial MR images of the spinal cord were essential in understanding the laterality of the spinal cord compression in spinal column disorders and in determining surgical approaches to the intramedullary lesions. Although non-invasive diagnostic modalities such as MR imaging and CT scans are adequate for deciding which surgical treatment to use in the majority of spine and spinal cord disorders, conventional myelography is still needed in the diagnosis of nerve root compression in some cases of cervical spondylosis.

    The objectives of this study were to investigate morbidity associated with heparin therapy in spinal surgery patients. The management of patients on anticoagulant therapy who undergo spinal surgery is becoming a common clinical problem. Although guidelines for the management of gastrointestinal endoscopy patients on heparin therapy have been published, spinal surgery may lead to specific complications, especially because of heparin therapy. However, only few studies have examined the clinical significance of heparin therapy in spinal surgery patients. The subjects of this study were 116 consecutive patients who were on anticoagulant or antiplatelet therapy. This says that all of the patients were receiving heparin or another anticoagunt. The patients were divided into 2 groups: a group that received heparin therapy before and after surgery (H group, n=25) and a group that did not receive heparin therapy (NH group, n=91). The results of clinical examinations and magnetic resonance imaging (MRI) in the 2 groups were compared. There were no significant differences between the 2 groups in baseline data. Comorbidities in both groups included valvular heart disease, atrial fibrillation, angina pectoris/myocardial infarction, and cerebral infarction. Mean intraoperative and postoperative blood loss in the H group were 324 ml and 536 ml, respectively, and the corresponding values in the NH group were 431 ml and 449 ml, respectively. MRI of all patients was performed within 10 days after surgery and T2-weighted images in the axial plane were examined for evidence of an epidural hematoma. Although the proportion of patients with an epidural hematoma, detected by MRI was higher in the H group than in the NH group (71% vs. 64%), none of the patients in either group required revision surgery because of intolerable pain or muscle weakness. Thrombocytopenia and skin necrosis were observed as complications of the heparin therapy in 1 patient in the H group (4%). The rate of

    2014-01-01

    Thoracoscopic surgery or video-assisted thoracic surgery (VATS) of the thoracic and lumbar spine has evolved greatly since it appeared less than 20 years ago. It is currently used in a large number of processes and injuries. The aim of this article, in its two parts, is to review the current status of VATS of the thoracic and lumbar spine in its entire spectrum. After reviewing the current literature, we developed each of the large groups of indications where VATS takes place, one by one. This second part reviews and discusses the management, treatment and specific thoracoscopic technique in thoracic disc herniation, spinal deformities, tumour pathology, infections of the spine and other possible indications for VATS. Thoracoscopic surgery is in many cases an alternative to conventional open surgery. The transdiaphragmatic approach has made endoscopic treatment of many thoracolumbar junction processes possible, thus widening the spectrum of therapeutic indications. These include the treatment of spinal deformities, spinal tumours, infections and other pathological processes, as well as the reconstruction of injured spinal segments and decompression of the spinal canal if lesion placement is favourable to antero-lateral approach. Good clinical results of thoracoscopic surgery are supported by growing experience reflected in a large number of articles. The degree of complications in thoracoscopic surgery is comparable to open surgery, with benefits in regard to morbidity of the approach and subsequent patient recovery.

    OBJECT Structural spinal surgery yields improvement in pain and disability for selected patients with spinal stenosis, spondylolisthesis, or a herniated intervertebral disc. A significant fraction of patients exhibit persistent postoperative neuropathic pain (PPNP) despite technically appropriate intervention, and such patients can benefit from spinal cord stimulation (SCS) to alleviate suffering. The complication profile of this therapy has not been systematically assessed and, thus, was the goal of this review. METHODS A comprehensive literature search was performed to identify prospective cohorts of patients who had PPNP following structurally corrective lumbar spinal surgery and who underwent SCS device implantation. Data about study design, technique of SCS lead introduction, and complications encountered were collected and analyzed. Comparisons of complication incidence were performed between percutaneously and surgically implanted systems, with the level of significance set at 0.05. RESULTS Review of 11 studies involving 542 patients formed the basis of this work: 2 randomized controlled trials and 9 prospective cohorts. Percutaneous implants were used in 4 studies and surgical implants were used in 4 studies; in the remainder, the types were undefined. Lead migration occurred in 12% of cases, pain at the site of the implantable pulse generator occurred in 9% of cases, and wound-related complications occurred in 5% of cases; the latter 2 occurred more frequently among surgically implanted devices. CONCLUSIONS Spinal cord stimulation can provide for improved pain and suffering and for decreased narcotic medication use among patients with PPNP after lumbar spinal surgery. This study reviewed the prospective studies forming the evidence base for this therapy, to summarize the complications encountered and, thus, best inform patients and clinicians considering its use. There is a significant rate of minor complications, many of which require further surgical

    Purpose Previous lumbar spinal surgery (PLSS) is not currently considered as a contraindication for regional anesthesia. However, there are still problems that make spinal anesthesia more difficult with a possibility of worsening the patient's back pain. Spinal anesthesia using combined spinal-epidural anesthesia (CSEA) in elderly patients with or without PLSS was investigated and the anesthetic characteristics, success rates, and possible complications were evaluated. Materials and Methods Fifty patients without PLSS (Control group) and 45 patients with PLSS (PLSS group) who were scheduled for total knee arthroplasty were studied prospectively. A CSEA was performed with patients in the left lateral position, and 10 mg of 0.5% isobaric tetracaine was injected through a 27 G spinal needle. An epidural catheter was then inserted for patient controlled analgesia. Successful spinal anesthesia was defined as adequate sensory block level more than T12. The number of skin punctures and the onset time were recorded, and maximal sensory block level (MSBL), time to 2-segment regression, success rate and complications were observed. Results The success rate of CSEA in Control group and PLSS group was 98.0%, and 93.3%, respectively. The median MSBL in PLSS group was higher than Control group [T4 (T2-L1) vs. T6 (T3-T12)] (p < 0.001). There was a significant difference in the number of patients who required ephedrine for the treatment of hypotension in PLSS group (p = 0.028). Conclusion The success rate of CSEA in patients with PLSS was 93.3%, and patients experienced no significant neurological complications. The MSBL can be higher in PLSS group than Control group.

    Adult spinal deformity (ASD) is an important problem to consider in the elderly. Although studies have examined the complications of ASD surgery and have compared functional and radiographic results of primary surgery versus revision, no studies have compared the costs of primary procedures with revisions. We assessed the in-hospital costs of these 2 surgery types in patients with ASD. The PearlDiver Database, a database of Medicare records, was used in this study. Mutually exclusive groups of patients undergoing primary or revision surgery were identified. Patients in each group were queried for age, sex, and comorbidities. Thirty-day readmission rates, 30-day and 90-day complication rates, and postoperative costs of care were assessed with multivariate analysis. For analyses, significance was set at P average reimbursement of the primary surgery cohort was $57,078 ± $30,767. Reimbursement of revision surgery cohort was $52,999 ± $27,658. The adjusted difference in average costs between the 2 groups is $4773 ± $1069 (P day and 90-day adjusted difference in cost of care when sustaining any of the major medical complications in primary surgery versus revision surgery was insignificant. Patients undergoing primary and revision corrective procedures for ASD have similar readmission rates, lengths of stays, and complication rates. Our data showed a higher cost of primary surgery compared with revision surgery, although costs of sustaining postoperative complications were similar. This finding supports the decision to perform revision procedures in patients with ASD when indicated because neither outcomes nor costs are a hindrance to correction. Copyright © 2017 Elsevier Inc.

    Full Text Available Cerebellar hemorrhage following a spinal surgery is extremely rare; however, considering the localization, it can cause major clinical manifestations. While it is considered that these types of bleedings occur secondary to a venous infarct, the pathogenesis is still unclear. A 57-year-old male patient who underwent a laminectomy by exposing T12-L5 and had pedicle screws placed for ankylosing spondylitis developed a CSF leak due to a 2 mm dural tear. A hemorrhage with parallel streaks on the left cerebellar hemisphere was seen in CT scan, and a thin subdural hematoma at right frontotemporal region was seen on cranial MRI, performed after the patient developed intense headache, nausea, vomiting, and stiff neck in the early postoperative period. In this paper, a case of cerebellar and subdural hematomas following a spinal surgery is discussed with its clinical and radiologic findings.

    Patients frequently have misconceptions regarding diagnosis, surgical indication, and expected outcome following spinal surgery for degenerative spinal disease. In this study, we sought to understand the relationship between patient-perceived surgical indications and patient expectations. We hypothesized that patients reporting appendicular symptoms as a primary surgical indication would report a higher rate of having expectations met by surgery compared to those patients reporting axial symptoms as a primary indication. Questionnaires were administered to patients who had undergone surgery for degenerative spinal disease at 2 tertiary care institutions. Questions assessed perception of the primary indication for undergoing surgery (radicular versus axial), whether the primary symptom improved after surgery, and whether patient expectations were met with surgery. Outcomes of interest included patient-reported symptomatic improvement following surgery and expectations met by surgery. Various factors were assessed for their relationship to these outcomes of interest. There were 151 unique survey respondents. Respondents were nearly split between having a patient-perceived indication for surgery as appendicular symptoms (55.6%) and axial symptoms (44.4%). Patient-perceived surgical indication being appendicular symptoms was the only factor predictive of patient-reported symptomatic improvement in our logistic regression model (OR 2.614; 95% CI 1.218-5.611). Patient-perceived surgical indication being appendicular symptoms (OR 3.300; 95% CI 1.575-6.944) and patient-reported symptomatic improvement (OR 33.297; 95% CI 12.186-90.979) were predictive of patients reporting their expectations met with surgery in both univariate and multivariate logistic regression modeling. We found that patient-reported appendicular symptoms as the primary indication for surgery were associated with a higher rate of both subjective improvement following surgery and having expectations met

    The plasma D-dimer levels of 136 patients (80 men and 56 women, mean age 63.9 years) who underwent spinal surgery in our hospital were measured on pod 3 and pod 7, as a method of screening for thromboembolic disease. A D-dimer cut off value of 10 μg/dl was used and only the patients with higher values were examined by CT. No patients had symptomatic thromboembolic disease. On pod 7 the D-dimer levels of 14 patients was above 10 μg/dl, but only 2 of them were detected in asymptomatic pulmonary embolism. Both of them had undergone anterior fusion surgery, and no deep venous thrombosis was detected in the lower extremities. Anticoagulation therapy with heparin and warfarin was started immediately, and the patients were discharged symptom-free. Another methods of thromboprophylaxis in addition to traditional mechanical thromboprophylaxis, such as by wearing compression stockings and foot pumps, may be necessary after anterior spinal surgery.

    Full Text Available Introduction: A restricted sympathetic block during spinal anesthesia may minimize hemodynamic changes. This prospective randomized study compared unilateral and bilateral spinal anesthesia with respect to the intra- and postoperative advantages and complications of each technique. Material and methods: Spinal anesthesia was induced with 0.5% hyperbaric bupivacaine and a 25-G Quincke needle (Dr. J in two groups of patients with physical status ASA I-II who had been admitted for orthopedic surgeries. In group A, dural puncture was performed with the patient in a seated position using 2.5 cm3 of hyperbaric bupivacaine. Each patient was then placed in the supine position. In group B, dural puncture was performed with the patient in the lateral decubitus position with 1.5 cm3 of hyperbaric bupivacaine. The lower limb was the target limb. The speed of injection was 1 mL/30 s, and the duration of time spent in the lateral decubitus position was 20 min. Results: The demographic data were similar in both groups. The time to the onset of the sensory and motor block was significantly shorter in group A (p = 0.00. The duration of motor and sensory block was shorter in group B (p < 0.05. The success rate for unilateral spinal anesthesia in group B was 94.45%. In two patients, the spinal block spread to the non-dependent side. The incidence of complications (nausea, headache, and hypotension was lower in group B (p = 0.02. Conclusion: When unilateral spinal anesthesia was performed using a low-dose, low-volume and low-flow injection technique, it provides adequate sensory-motor block and helps to achieve stable hemodynamic parameters during orthopedic surgery on a lower limb. Patients were more satisfied with this technique as opposed to the conventional approach. Furthermore, this technique avoids unnecessary paralysis on the non-operated side.

    Full Text Available BACKGROUND: Tranexamic acid (TXA is well-established as a versatile oral, intramuscular, and intravenous (IV antifibrinolytic agent. However, the efficacy of IV TXA in reducing perioperative blood transfusion in spinal surgery is poorly documented. METHODOLOGY: We conducted a meta-analysis of randomized controlled trials (RCTs and quasi-randomized (qi-RCTs trials that included patients for various spinal surgeries, such as adolescent scoliosis surgery administered with perioperative IV TXA according to Cochrane Collaboration guidelines using electronic PubMed, Cochrane Central Register of Controlled Trials, and Embase databases. Additional journal articles and conference proceedings were manually located by two independent researchers. RESULTS: Totally, nine studies were included, with a total sample size of 581 patients. Mean blood loss was decreased in patients treated with perioperative IV TXA by 128.28 ml intraoperatively (ranging from 33.84 to 222.73 ml, 98.49 ml postoperatively (ranging from 83.22 to 113.77 ml, and 389.21 ml combined (ranging from 177.83 to 600.60 ml. The mean volume of transfused packed cells were reduced by 134.55 ml (ranging 51.64 to 217.46 (95% CI; P = 0.0001. Overall, the number of patients treated with TXA who required blood transfusions was lower by 35% than that of patients treated with the comparator and who required blood transfusions (RR 0.65; 95% CI; 0.53 to 0.85; P<0.0001, I(2 = 0%. A dose-independent beneficial effect of TXA was observed, and confirmed in subgroup and sensitivity analyses. A total of seven studies reported DVT data. The study containing only a single DVT case was not combined. CONCLUSIONS: The blood loss was reduced in spinal surgery patients with perioperative IV TXA treatment. Also the percentage of spinal surgery patients who required blood transfusion was significantly decreased. Further evaluation is required to confirm our findings before TXA can be safely used in patients

    Venous thromboembolic events result in significant morbidity, mortality, and costly therapeutic interventions. As medical resource allocation strategies are becoming more pervasive, appropriate risk stratification and prophylactic regimens are essential. Previous studies have shown a decreased incidence of perioperative venous thromboembolism in the chronic spinal cord injury population. The question remains of whether chronic spinal cord injury is protective against venous thromboembolism. A retrospective review of all cases involving chronic spinal cord injury patients who underwent plastic and reconstructive surgery operations (n = 424) and general surgery patients (n = 777) with a primary outcome of deep venous thrombosis or pulmonary embolism within 90 days of surgery was performed. The incidence of postoperative deep venous thrombosis in the control and spinal cord injury groups was 1.7 percent and 0.2 percent, respectively (p = 0.027). However, such significance was not observed with regard to postoperative pulmonary embolism incidence (p = 0.070). Collectively, the incidence of postoperative venous thromboembolism-specifically, deep venous thrombosis or pulmonary embolism-was significantly greater in the general surgery population (p = 0.014). A nearly 10-fold increased risk of venous thromboembolism was seen among the control group (1.9 percent versus 0.2 percent) despite administration of optimal prophylaxis. This study demonstrates a profoundly low incidence of venous thromboembolism among chronic spinal cord injury patients compared with general surgery patients. Future efforts to elucidate how chronic spinal cord injury confers a protective mechanism may potentially influence the evolution of venous thromboembolism prevention guidelines, and spark the development of alternative prophylactic agents or customized application of prevention efforts.

    A systematic review. A systematic literature review of the clinical data from prospective studies was undertaken to assess the efficacy of spinal cord stimulation (SCS) in the treatment of failed back surgery syndrome (FBSS) in adults. For patients with unrelenting back pain due to mechanical instability of the spine, degenerative disc disease, spinal injury, or deformity, spinal surgery is a well-accepted treatment option; however, even after surgical intervention, many patients continue to experience chronic back pain that can be notoriously difficult to treat. Clinical evidence suggests that for patients with FBSS, repeated surgery will not likely offer relief. Additionally, evidence suggests long-term use of opioid pain medications is not effective in this population, likely presents additional complications, and requires strict management. A systematic literature review was performed using several bibliographic databases, prospective studies in adults using SCS for FBSS were included. SCS has been shown to be a safe and efficacious treatment for this patient population. Recent technological developments in SCS offer even greater pain relief to patients' refractory to other treatment options, allowing patients to regain functionality and improve their quality of life with significant reductions in pain.

    To determine the integrity of microscope covers and bacterial contamination at the end of lumbar spinal decompressive surgery. A prospective study of 25 consecutive lumbar spinal decompressions with the use of a surgical microscope was performed. For detection of perforations, the microscope covers were filled with water at the end of surgery and the presence of water leakage in 3 zones (objective, ocular and control panel) was examined. For detection of bacterial contamination, swabs were taken from the covers at the same locations before and after surgery. Among the 25 covers, 1 (4%) perforation was observed and no association between perforation and bacterial contamination was seen; 3 (4%) of 75 smears from the 25 covers showed post-operative bacterial contamination, i.e. 2 in the ocular zone and 1 in the optical zone, without a cover perforation. The incidence of microscope cover perforation was very low and was not shown to be associated with bacterial contamination. External sources of bacterial contamination seem to outweigh the problem of contamination due to failure of cover integrity. © 2014 S. Karger AG, Basel.

    Osteoporosis has become a major medical problem as the aged population of the world rapidly grows. Osteoporosis predisposes patients to fracture, progressive spinal deformities, and stenosis, and is subject to be a major concern before performing spine surgery, especially with bone fusions and instrumentation. Osteoporosis has often been considered a contraindication for spinal surgery, while in some instances patients have undergone limited and inadequate procedures in order to avoid concomitant instrumentation. As the population ages and the expectations of older patients increase, the demand for surgical treatment in older patients with osteoporosis and spinal degenerative diseases becomes progressively more important. Nowadays, advances in surgical and anesthetic technology make it possible to operate successfully on elderly patients who no longer accept disabling physical conditions. This article discusses the biomechanics of the osteoporotic spine, the diagnosis and management of osteoporotic patients with spinal conditions, as well as the novel treatments, recommendations, surgical indications, strategies and instrumentation in patients with osteoporosis who need spine operations.

    Full Text Available The purpose of the reviewThe analysis of the components of enhanced recovery after surgery (ERAS protocols in urologic surgery.Recent findingsERAS protocols has been studied for over 20 years in different surgical procedures, mostly in colorectal surgery. The concept of improving patient care and reducing postoperative complications was also applied to major urologic surgery and especially procedure of radical cystectomy. This procedure is technically challenging, due to a major surgical resection and high postoperative complication rate that may reach 65%. Several clinical pathways were introduced to improve perioperative course and reduce the length of hospital stay. These protocols differ from ERAS modalities in other surgeries. The reasons for this are longer operative time, increased risk of perioperative transfusion and infection, and urinary diversion achieved using transposed intestinal segments. Previous studies in this area analyzed the need for mechanical bowel preparation, postoperative nasogastric tube decompression, as well as the duration of urinary drainage. Furthermore, the attention has also been drawn to perioperative fluid optimization, pain management, and bowel function.SummaryNotwithstanding partial resemblance between the pathways in major urologic surgery and other pelvic surgeries, there are still scarce guidelines for ERAS protocols in urology, which is why further studies should assess the importance of preoperative medical optimization, implementation of thoracic epidural anesthesia and analgesia, and perioperative nutritional management.

    MINI: We assessed 90-day readmission and evaluated risk factors associated with readmission after lumbar spinal fusion surgery in New York State. The overall 90-day readmission rate was 24.8%. Age, sex, race, insurance, procedure, number of operated spinal levels, health service area, and comorbidities are major risk factors for 90-day readmission. Retrospective cohort study. The aim of this study was to assess 90-day readmission and evaluate risk factors associated with readmission after lumbar fusion in New York State. Readmission is becoming an important metric for quality and efficiency of health care. Readmission and its predictors following spine surgery are overall poorly understood and limited evidence is available specifically in lumbar fusion. The New York Statewide Planning and Research Cooperative System (SPARCS) was utilized to capture patients undergoing lumbar fusion from 2005 to 2014. Temporal trend of 90-day readmission was assessed using Cochran-Armitage test. Logistic regression was used to examine predictors associated with 90-day readmission. There were 86,869 patients included in this cohort study. The overall 90-day readmission rate was 24.8%. On a multivariable analysis model, age (odds ratio [OR] comparing ≥75 versus New York-Pennsylvania border: 0.67, 95% CI: 0.61-0.73), and comorbidity, i.e., coronary artery disease (OR: 1.26, 95% CI: 1.19-1.33) were significantly associated with 90-day readmission. Directions of the odds ratios for these factors were consistent after stratification by procedure type. Age, sex, race, insurance, procedure, number of operated spinal levels, HSA, and comorbidities are major risk factors for 90-day readmission. Our study allows risk calculation to determine high-risk patients before undergoing spinal fusion surgery to prevent early readmission, improve quality of care, and reduce health care expenditures. 3.

    Full Text Available Gut barrier loss has been implicated as a critical event in the occurrence of postoperative complications. We aimed to study the development of gut barrier loss in patients undergoing major non-abdominal surgery.Twenty consecutive children undergoing spinal fusion surgery were included. This kind of surgery is characterized by long operation time, significant blood loss, prolonged systemic hypotension, without directly leading to compromise of the intestines by intestinal manipulation or use of extracorporeal circulation. Blood was collected preoperatively, every two hours during surgery and 2, 4, 15 and 24 hours postoperatively. Gut mucosal barrier was assessed by plasma markers for enterocyte damage (I-FABP, I-BABP and urinary presence of tight junction protein claudin-3. Intestinal mucosal perfusion was measured by gastric tonometry (P(rCO2, P(r-aCO2-gap. Plasma concentration of I-FABP, I-BABP and urinary expression of claudin-3 increased rapidly and significantly after the onset of surgery in most children. Postoperatively, all markers decreased promptly towards baseline values together with normalisation of MAP. Plasma levels of I-FABP, I-BABP were significantly negatively correlated with MAP at (1/2 hour before blood sampling (-0.726 (p<0.001, -0.483 (P<0.001, respectively.

This kind of surgery is characterized by long operation time, significant blood loss, prolonged systemic hypotension, without directly leading to compromise of the intestines by intestinal manipulation or use of extracorporeal circulation. Blood was collected preoperatively, every two hours during surgery and 2, 4, 15 and 24 hours postoperatively. Gut mucosal barrier was assessed by plasma markers for enterocyte damage (I-FABP, I-BABP) and urinary presence of tight junction protein claudin-3. Intestinal mucosal perfusion was measured by gastric tonometry (PrCO2, Pr-aCO2-gap). Plasma concentration of I-FABP, I-BABP and urinary expression of claudin-3 increased rapidly and significantly after the onset of surgery in most children. Postoperatively, all markers decreased promptly towards baseline values together with normalisation of MAP. Plasma levels of I-FABP, I-BABP were significantly negatively correlated with MAP at ½ hour before blood sampling (−0.726 (p<0.001), −0.483 (P<0.001), respectively).

    Full Text Available Abstract Background There is some evidence from a Cochrane review that rehabilitation following spinal surgery may be beneficial. Methods We conducted a survey of current post-operative practice amongst spinal surgeons in the United Kingdom in 2002 to determine whether such interventions are being included routinely in the post-operative management of spinal patients. The survey included all surgeons who were members of either the British Association of Spinal Surgeons (BASS or the Society for Back Pain Research. Data on the characteristics of each surgeon and his or her current pattern of practice and post-operative care were collected via a reply-paid postal questionnaire. Results Usable responses were provided by 57% of the 89 surgeons included in the survey. Most surgeons (79% had a routine post-operative management regime, but only 35% had a written set of instructions that they gave to their patients concerning this. Over half (55% of surgeons do not send their patients for any physiotherapy after discharge, with an average of less than two sessions of treatment organised by those that refer for physiotherapy at all. Restrictions on lifting, sitting and driving showed considerable inconsistency both between surgeons and also within the recommendations given by individual surgeons. Conclusion Demonstrable inconsistencies within and between spinal surgeons in their approaches to post-operative management can be interpreted as evidence of continuing and significant uncertainty across the sub-speciality as to what does constitute best care in these areas of practice. Conducting further large, rigorous, randomised controlled trials would be the best method for obtaining definitive answers to these questions.

    Full Text Available To analyze the occurrence, risk factors, treatment and prognosis of postoperative pleural effusion after spinal deformity correction surgery.The clinical and imaging data of 3325 patients undergoing spinal deformity correction were collected from the database of our hospital. We analyzed the therapeutic process of the 28 patients who had postoperative pleural effusion, and we identified the potential risk factors using logistic regression.Among the 28 patients with postoperative pleural effusion, 24 (85.7% suffered from hemothorax, 2 (7.1% from chylothorax, and 2 (7.1% from subarachnoid-pleural fistula. The pleural effusion occurred on the convex side in 19 patients (67.9%, on the concave side in 4 patients (14.3%, and on both sides in 4 patients (14.3%. One patient with left hemothorax was diagnosed with kyphosis. The treatment included conservative clinical observation for 5 patients and chest tube drainage for 23 patients. One patient also underwent thoracic duct ligation and pleurodesis. All of these treatments were successful. Logistic regression analysis showed that adult patients(≥18 years old, congenital scoliosis, osteotomy and thoracoplasty were risk factors for postoperative pleural effusion in spinal deformity correction surgery.The incidence of postoperative pleural effusion in spinal deformity correction surgery was approximately 0.84% (28/3325, and hemothorax was the most common type. Chest tube drainage treatment was usually successful, and the prognosis was good. Adult patients(≥18 years old, congenital scoliosis, and had undergone osteotomy or surgery with thoracoplasty were more likely to suffer from postoperative pleural effusion.

    Objective: To assess the feasibility and efficacy of a novel, minimally invasive spinal surgery technique for the correction of lumbar spinal stenosis involving unilateral approach for bilateral decompression. Study Design: Cross-sectional observational study. Place and Duration of Study: Neurosurgery Department of PGMI, Lady Reading Hospital, Peshawar, from January to December 2010. Methodology: A total of 60 patients with lumbar stenosis were randomly assigned to undergo either a conventional laminectomy (30 patients, Group A), or a unilateral approach (30 patients, Group B). Clinical outcomes was measured using the scale of Finneson and Cooper. All the data was collected by using a proforma and different parameters were assessed for a minimum follow-up period of three months. Data was analyzed by descriptive statistics using SPSS software version 17. Results: Adequate decompression was achieved in all patients. Compared with patients in the conventional laminectomy group, patients who received the novel procedure (unilateral approach) had a reduced mean duration of hospital stay, a faster recovery rate and majority of the patients (88.33%) had an excellent to fair operative result according to the Finneson and Cooper scale. Five major complications occurred in all patient groups, 2 patients had unintended dural rent and 2 wound dehiscence each and fifth patient had worsening of symptoms. There was no mortality in the series. Conclusion: The ultimate goal of the unilateral approach to treat lumbar spinal stenosis is to achieve adequate decompression of the neural elements. An additional benefit of a minimally invasive approach is adequate preservation of vertebral stability, as it requires only minimal muscle trauma, preservation of supraspinous/intraspinous ligament complex and spinous process, therefore, allows early mobilization. This also shortens the hospital stay, reduces postoperative back pain, and leads to satisfactory outcome. (author)

    Combined spinal epidural anesthesia (CSEA) has advantages over single injection epidural or subarachnoid blockades. The objective of this report was to present a case in which segmental subarachnoid block can be an effective technique for gastrointestinal surgery with spontaneous respiration. Patient with physical status ASA III, with diabetes mellitus type II, hypertension, and chronic obstructive pulmonary disease was scheduled for resection of a right colon tumor. Combined spinal epidural block was performed in the T5-T6 space and 8 mg of 0.5% isobaric bupivacaine with 50 microg of morphine were injected in the subarachnoid space. The epidural catheter (20G) was introduced four centimeters in the cephalad direction. Sedation was achieved with fractionated doses of 1 mg of midazolam (total of 6 mg). A bolus of 25 mg of 0.5% bupivacaine was administered through the catheter two hours after the subarachnoid block. Vasopressors and atropine were not used. This case provides evidence that segmental spinal block can be the anesthetic technique used in gastrointestinal surgeries with spontaneous respiration.

    Full Text Available BACKGROUND AND OBJECTIVES: Changes in ocular perfusion play an important role in the pathogenesis of ischemic optic neuropathy. Ocular perfusion pressure is equal to mean arterial pressure minus intraocular pressure. The aim of this study was to evaluate the changes in the intraocular pressure and the retinal nerve fiber layer thickness in patients undergoing spinal surgery in the prone position. METHODS: This prospective study included 30 patients undergoing spinal surgery. Retinal nerve fiber layer thickness were measured one day before and after the surgery by using optical coherence tomography. Intraocular pressure was measured by tonopen six times at different position and time-duration: supine position (baseline; 10 min after intubation (Supine 1; 10 (Prone 1, 60 (Prone 2, 120 (Prone 3 min after prone position; and just after postoperative supine position (Supine 2. RESULTS: Our study involved 10 male and 20 female patients with the median age of 57 years. When postoperative retinal nerve fiber layer thickness measurements were compared with preoperative values, a statistically significant thinning was observed in inferior and nasal quadrants (p = 0.009 and p = 0.003, respectively. We observed a statistically significant intraocular pressure decrease in Supine 1 and an increase in both Prone 2 and Prone 3 when compared to the baseline. Mean arterial pressure and ocular perfusion pressure were found to be significantly lower in Prone 1, Prone 2 and Prone 3, when compared with the baseline. CONCLUSIONS: Our study has shown increase in intraocular pressure during spinal surgery in prone position. A statistically significant retinal nerve fiber layer thickness thinning was seen in inferior and nasal quadrants one day after the spinal surgery.

    Full Text Available Abstract Background Secondary systemic vasculitis after posterior spinal fusion surgery is rare. It is usually related to over-reaction of immune-system, to genetic factors, toxicity, infection or metal allergies. Case Description A 14 year-old girl with a history of extended posterior spinal fusion due to idiopathic scoliosis presented to our department with diffuse erythema and nephritis (macroscopic hemuresis and proteinuria 5 months post surgery. The surgical trauma had no signs of inflammation or infection. The blood markers ESR and CRP were increased. Skin tests were positive for nickel allergy, which is a content of titanium alloy. The patient received corticosteroids systematically (hydrocortisone 10 mg for 6 months, leading to total recess of skin and systemic reaction. However, a palpable mass close to the surgical wound raised the suspicion of a late infection. The patient had a second surgery consisting of surgical debridement and one stage revision of posterior spinal instrumentation. Intraoperative cultures were positive to Staphylococcus aureus. Intravenous antibiotics were administered. The patient is now free of symptoms 24 months post revision surgery without any signs of recurrence of either vasculitis or infection. Literature Review Systemic vasculitis after spinal surgery is exceptionally rare. Causative factors are broad and sometimes controversial. In general, it is associated with allergy to metal ions. This is usually addressed with metal on metal total hip bearings. In spinal surgery, titanium implants are considered to be inert and only few reports have presented cases with systemic vasculitides. Therefore, other etiologies of immune over-reaction should always be considered, such as drug toxicity, infection, or genetic predisposition. Purposes and Clinical Relevance Our purpose was to highlight the difficulties during the diagnostic work-up for systemic vasculitis and management in cases of posterior spinal surgery.

    Full Text Available Achondroplasia is the commonest form of short-limbed dwarfism and occurs in 1:26,000- 40,000 live births. This is an autosomal dominant disorder with abnormal endochondral ossification whereas periosteal and intramembranous ossification are normal. The basic abnormality is a disturbance of cartilage formation mainly at the epiphyseal growth plates and at the base of the skull. The anesthetic management of achondroplastic dwarfs is a challenge to the anesthesiologist. Both regional as well as general anesthesia have their individual risks and consequences. We report a case of an achondroplastic dwarf in whom combined spinal epidural anesthesia was used for fixation of a fractured femur. The patient had undergone previous femur surgery under general anesthesia since he had been informed that spinal anesthesia could be very problematic. There was no technical difficulty encountered during the procedure and an adequate level was achieved with low-dose local anesthetics without any problem. Postoperative pain relief was offered for three consecutive postoperative days using epidural tramadol. We discuss the anesthetic issues and highlight the role of combined spinal epidural anesthesia with low-dose local anesthetics in this patient. This approach also helped in early ambulation and postoperative pain relief.

    The aim of the investigation was to evaluate poor outcome following spinal cervical surgery. A total of 146 consecutive patients operated with anterior discectomy and fusion (ADF) with the Cloward technique were investigated. Clinical notes, plain radiography, CT, and fast spin-echo (FSE) images were retrospectively evaluated. Some 30% of the patients had unsatisfactory clinical results within 12 months after surgery; 13% had initial improvement followed by deterioration of the preoperative symptoms, while 14.4% were not improved or worsened. Disc herniation and bony stenosis above, below, or at the fused level were the most common findings. In 45% of patients, surgery failed to decompress the spinal canal. In only 4 patients was no cause of remaining myelopathy and/or radiculopathy found. FSE demonstrated a large variety of pathological findings in the patients with poor clinical outcome after ADF. Postoperatively, patients with good clinical outcome had a lower incidence of pathological changes. FSE is considered the primary imaging modality for the cervical spine. However, CT is a useful complement in the axial projection to visualize bone changes. (orig.)

  5. Biomechanical implications of lumbar spinal ligament transection.

    2014-11-01

    Many lumbar spine surgeries either intentionally or inadvertently damage or transect spinal ligaments. The purpose of this work was to quantify the previously unknown biomechanical consequences of isolated spinal ligament transection on the remaining spinal ligaments (stress transfer), vertebrae (bone remodelling stimulus) and intervertebral discs (disc pressure) of the lumbar spine. A finite element model of the full lumbar spine was developed and validated against experimental data and tested in the primary modes of spinal motion in the intact condition. Once a ligament was removed, stress increased in the remaining spinal ligaments and changes occurred in vertebral strain energy, but disc pressure remained similar. All major biomechanical changes occurred at the same spinal level as the transected ligament, with minor changes at adjacent levels. This work demonstrates that iatrogenic damage to spinal ligaments disturbs the load sharing within the spinal ligament network and may induce significant clinically relevant changes in the spinal motion segment.

    Surgery for spinal intramedullary tumors remains one of the major challenges for neurosurgeons, due to their relative infrequency, unknown natural history, and surgical difficulty. We are sure that safe and precise resection of spinal intramedullary tumors, particularly encapsulated benign tumors, can result in acceptable or satisfactory postoperative outcomes. General surgical concepts and strategies, technical consideration, and functional outcomes after surgery are discussed with illustrative cases of spinal intramedullary benign tumors such as ependymoma, cavernous malformation, and hemangioblastoma. Selection of a posterior median sulcus, posterolateral sulcus, or direct transpial approach was determined based on the preoperative imaging diagnosis and careful inspection of the spinal cord surface. Tumor-cord interface was meticulously delineated in cases of benign encapsulated tumors. Our retrospective functional analysis of 24 consecutive cases of spinal intramedullary ependymoma followed for at least 6 months postoperatively demonstrated a mean grade on the modified McCormick functional schema of 1.8 before surgery, deteriorating significantly to 2.6 early after surgery ( 6 months after surgery). The risk of functional deterioration after surgery should be taken into serious consideration. Functional deterioration after surgery, including neuropathic pain even long after surgery, significantly affects patient quality of life. Better balance between tumor control and functional preservation can be achieved not only by the surgical technique or expertise, but also by intraoperative neurophysiological monitoring, vascular image guidance, and postoperative supportive care. Quality of life after surgery should inarguably be given top priority.

    In practice, trauma and orthopedic surgery during spinal anesthesia are often performed with routine urethral catheterization of the bladder to prevent an overdistention of the bladder. However, use of a catheter has inherent risks. Ultrasound examination of the bladder (Bladderscan) can precisely determine the bladder volume. Thus, the aim of this study was to identify parameters indicative of urinary retention after low-dose spinal anesthesia and to develop a simple algorithm for patient care. This prospective pilot study approved by the Ethics Committee enrolled 45 patients after obtaining their written informed consent. Patients who underwent arthroscopic knee surgery received low-dose spinal anesthesia with 1.4 ml 0.5% bupivacaine at level L3/L4. Bladder volume was measured by urinary bladder scanning at baseline, at the end of surgery and up to 4 h later. The incidence of spontaneous urination versus catheterization was assessed and the relative risk for catheterization was calculated. Mann-Whitney test, chi(2) test with Fischer Exact test and the relative odds ratio were performed as appropriate. *P 300 ml postoperatively had a 6.5-fold greater likelihood for urinary retention. In the management of patients with short-lasting spinal anesthesia for arthroscopic knee surgery we recommend monitoring bladder volume by Bladderscan instead of routine catheterization. Anesthesiologists or nurses under protocol should assess bladder volume preoperatively and at the end of surgery. If bladder volume is >300 ml, catheterization should be performed in the OR. Patients with a bladder volume of 500 ml.

    To determine variables which affect cost and profit for major ear surgery and perform a break-even analysis. Retrospective financial analysis. UK teaching hospital. Patients who underwent major ear surgery under general anaesthesia performed by the senior author in main theatre over a 2-year period between dates of 07 September 2010 and 07 September 2012. Income, cost and profit for each major ear patient spell. Variables that affect major ear surgery profitability. Seventy-six patients met inclusion criteria. Wide variation in earnings, with a median net loss of £-1345.50 was observed. Income was relatively uniform across all patient spells; however, theatre time of major ear surgery at a cost of £953.24 per hour varied between patients and was the main determinant of cost and profit for the patient spell. Bivariate linear regression of earnings on theatre time identified 94% of variation in earnings was due to variation in theatre time (r = -0.969; P break-even time for major ear surgery of 110.6 min. Theatre time was dependent on complexity of procedure and number of OPCS4 procedures performed, with a significant increase in theatre time when three or more procedures were performed during major ear surgery (P = 0.015). For major ear surgery to either break-even or return a profit, total theatre time should not exceed 110 min and 36 s. © 2015 John Wiley & Sons Ltd.

    Minimally invasive spine surgery (MISS) seems to have many benefits for human patients and is currently used for various minor and major spine procedures. For MISS, a change in access strategy to the target location is necessary and it requires intraoperative imaging, special instrumentation, and magnification. Few veterinary studies have evaluated MISS for canine patients for spinal decompression procedures. This article discusses the general requirements for MISS and how these can be applied to veterinary spinal surgery. The current veterinary MISS literature is reviewed and suggestions are made on how to apply MISS to different spinal locations. Copyright © 2017 Elsevier Inc. All rights reserved.

    OBJECTIVE Spinal dural arteriovenous fistulas (dAVFs) are rare vascular abnormalities caused by arteriovenous shunting. They often form at the dural root sleeve between a radicular feeding artery and draining medullary vein causing venous congestion and edema, decreased perfusion, and ischemia of the spinal cord. Treatment consists of either surgical ligation of the draining vein or selective embolization via an endovascular approach. There is a paucity of data on which modality provides more durable and effective outcomes. METHODS The authors performed a retrospective review of a prospectively maintained database by the senior author to assess clinical outcomes in patients undergoing surgical treatment of spinal dAVFs. Preoperative and postoperative motor and Aminoff-Logue Scale (ALS) scores were collected. RESULTS A total of 41 patients with 44 spinal dAVFs were identified, with a mean patient age of 64 years. The mean symptom duration was 14 months, with weakness (82%), urinary symptoms (47%), and sensory symptoms (29%) at presentation. The fistula locations were as follows: 30 thoracic, 9 lumbar, 3 sacral, and 2 cervical. Five patients had normal motor and ALS scores at presentation. Among the remaining 36 patients with motor deficits or abnormal gait and micturition at presentation, 78% experienced an improvement while the remaining 22% continued to be stable. There was a trend toward improved outcomes in patients with shorter symptom duration; mean symptom duration among patients with clinical improvement was 13 months compared with 22 months among those without improvement. Additionally, rates of improvement were higher for lower thoracic and lumbosacral dAVFs (85% and 83%) compared with those in the upper thoracic spine (57%). No patient developed recurrent fistulas or worsening neurological deficits. CONCLUSIONS Surgery is associated with excellent outcomes in the treatment of spinal dAVFs. Early diagnosis and treatment are critical, with a trend toward

    The purpose of this study is to clarify the correlation between electrophysiological examination and MRI diagnosis. Twenty-four patients with cervical spondylotic myelopathy were examined with magnetic resonance imaging and evoked spinal cord potentials (ESCPs) before surgery. In all the patients, only the intervertebral level was symptomatic, as shown by ESCPs. ESCPs following median nerve stimulation (MN-ESCPs), transcranial electric stimulation (TCE-ESCPs), and spinal cord stimulation (Spinal-ECSPs) were recorded. The patients were grouped into two groups as follows: group A, all ESCPs were abnormal; group B, normal spinal cord stimulation. Spinal cord transverse area and compression ratio (central and 1/4-lateral anteroposterior diameter divided by transverse diameter) were measured on T1-weighted axial imaging, with abnormal ESCPs as indicators of spinal cord morphology. Central and 1/4-lateral compression ratio was significantly lower in group A. Spinal cord morphology of magnetic resonance imaging is useful for functional diagnosis. (author)

    This study is aimed at conducting a program for two different anesthetic methods used during a spinal fusion surgery to ensure better intra-operative hemodynamic stability and post-operative pain control. A prospective, randomized, double blind study in patients scheduled for spinal fusion surgery, who were randomly allocated to two groups, G1 and G2, (n = 15 per group), class I-II ASA, was carried out. Both groups received pre-operatively midazolam, followed intra-operatively by propofol, sevoflurane, atracurium, and either remifentanil infusion 0.2 microg/kg/min (G1), or the same dose of remifentanil infusion and low doses of ketamine infusion 1 microg/kg/min (G2) anesthetics, antidote medication and post-operative morphine doses. HR, MAP, vital signs, surgical bleeding, urine output, duration of surgery and duration of anesthesia were recorded. In a 24-h recovery period in a post-anesthesia care unit (PACU) the recovery time, the first pain score and analgesic requirements were measured. Intra-operative HR and arterial BP were significantly less (p < 0.05) in G1 as compared to G2. In the PACU the first pain scores were significantly less (p < 0.05) in G2 than in G1. The time for the first patient analgesia demand dose was greater in G2, as also morphine consumption which was greater in G1 than G2 (p < 0.05). Other results were the same. None of the patients had any adverse drug reaction. Adding low doses of ketamine hydrochloride could be a routine therapy to improve the hemodynamic stability and reduce the post-operative morphine consumption during spinal fusion surgery.

    Paraplegia is an uncommon yet devastating complication following thoracotomy, usually caused by compression or ischemia of the spinal cord. Ischemia without compression may be a result of global ischemia, vascular injury and other causes. Epidural anesthesia has been implicated as a major cause. This report highlights the fact that perioperative cord ischemia and paraplegia may be unrelated to epidural intervention. A 71-yr-old woman was admitted for a left upper lobectomy for resection of a non-small cell carcinoma of the lung. The patient refused epidural catheter placement and underwent a left T5-6 thoracotomy under general anesthesia. During surgery, she was hemodynamically stable and good oxygen saturation was maintained. Several hours following surgery the patient complained of loss of sensation in her legs. Neurological examination disclosed a complete motor and sensory block at the T5-6 level. Magnetic resonance imaging (MRI) revealed spinal cord ischemia. The patient received iv steroid treatment, but remained paraplegic. Five months following the surgery there was only partial improvement in her motor symptoms. A follow-up MRI study was consistent with a diagnosis of spinal cord ischemia. In this case of paraplegia following thoracic surgery for lung resection, epidural anesthesia/analgesia was not used. The MRI demonstrated evidence of spinal cord ischemia, and no evidence of cord compression. This case highlights that etiologies other than epidural intervention, such as injury to the spinal segmental arteries during thoracotomy, should be considered as potential causes of cord ischemia and resultant paraplegia in this surgical population.

    Full Text Available We present our perioperative minimally invasive spine surgery technique using intraoperative computed tomography image-guided navigation for the treatment of various lumbar spine pathologies. We present an illustrative case of a patient undergoing minimally invasive percutaneous posterior spinal fusion assisted by the O-arm system with navigation. We discuss the literature and the advantages of the technique over fluoroscopic imaging methods: lower occupational radiation exposure for operative room personnel, reduced need for postoperative imaging, and decreased revision rates. Most importantly, we demonstrate that use of intraoperative cone beam CT image-guided navigation has been reported to increase accuracy.

    The prevalence of adult spinal deformity has been increasing exponentially over time. Surgery has been credited with good radiological and clinical results. The incidence of complications is high. MIS techniques provide good results with fewer complications. This is a retrospective study of 25 patients with an adult spinal deformity treated by MIS surgery, with a minimum follow-up of 6 months. Radiological improvement was SVA from 5 to 2cm, coronal Cobb angle from 31° to 6°, and lumbar lordosis from 18° to 38°. All of these parameters remained stable over time. We also present the complications that appeared in 4 patients (16%). Only one patient needed reoperation. We describe the technique used and review the references on the subject. We conclude that the MIS technique for treating adult spinal deformity has comparable results to those of the conventional techniques but with fewer complications. Copyright © 2017 SECOT.

    To explore the effectiveness of 10 kHz high frequency spinal cord stimulation (HF10 therapy) treatment of chronic low back pain in patients who have not had spinal surgery. Patients with chronic low back pain without prior spinal surgery were evaluated by a team of spine surgeons to rule out any spinal pathology amenable to surgical interventions and by a multidisciplinary pain team to confirm eligibility for the study. After a successful (>50% back pain reduction) trial of HF10 therapy, enrolled subjects underwent permanent system implantation and were followed-up one year post-implant. About 95% of the enrolled subjects (20/21) received the permanent system. At 12 months post-implant, both back pain VAS score and ODI were significantly reduced compared with baseline values (by 73% and 48%, respectively); an estimated quality-adjusted life year gain of 0.47 and a reduction in opioid use by 64% was observed. Four more patients among those unable to work at baseline due to back pain were employed at 12 months post-implant. There were no serious adverse events. HF10 therapy may provide significant back pain relief, reduction in disability, improvement quality of life, and reduction in opioid use in chronic low back pain not resulting from spinal surgery. © 2016 The Authors.

    Control of persistent pain following spinal surgery is an unmet clinical need. This study compared the efficacy and safety of buprenorphine transdermal system (BTDS) to oral tramadol/acetaminophen (TA) in Korean patients with persistent, moderate pain following spinal surgery. Open-label, interventional, randomized multicenter study. Adults with persistent postoperative pain (Numeric Rating Scale [NRS] ≥ 4 at 14-90 days postsurgery) were enrolled. Patients received once-weekly BTDS ( n = 47; 5  μ g/h titrated to 20  μ g/h) or twice-daily TA ( n = 40; tramadol 37.5 mg/acetaminophen 325 mg, one tablet titrated to 4 tablets) for 6 weeks. The study compared pain reduction with BTDS versus TA at week 6. Quality of life (QoL), treatment satisfaction, medication compliance, and adverse events (AEs) were assessed. At week 6, both groups reported significant pain reduction (mean NRS change: BTDS -2.02; TA -2.76, both P pain following spinal surgery, BTDS is an alternative to TA for reducing pain and supports medication compliance.

    Surgical site infection is a serious and significant complication after spinal surgery and is associated with high morbidity rates, high healthcare costs and poor patient outcomes. Accurate identification of risk factors is essential for developing strategies to prevent devastating infections. The purpose of this study was to identify independent risk factors for surgical site infection among posterior thoracic and/or lumbar spinal surgery in adult patients using a prospective multicenter surveillance research method. From July 2010 to June 2012, we performed a prospective surveillance study in adult patients who had developed surgical site infection after undergoing thoracic and/or lumbar posterior spinal surgery at 11 participating hospitals. Detailed preoperative and operative patient characteristics were prospectively recorded using a standardized data collection format. Surgical site infection was based on the definition established by the Centers for Disease Control and Prevention. A total of 2,736 consecutive adult patients were enrolled, of which 24 (0.9%) developed postoperative deep surgical site infection. Multivariate regression analysis indicated four independent risk factors. Preoperative steroid therapy (P = 0.001), spinal trauma (P = 0.048) and gender (male) (P = 0.02) were statistically significant independent patient-related risk factors, whereas an operating time ≥3 h (P operating time ≥3 h were independent risk factors for deep surgical site infection after thoracic and/or lumbar spinal surgery in adult patients. Identification of these risk factors can be used to develop protocols aimed at decreasing the risk of surgical site infection.

    Complications associated with prone surgical positioning during elective spine surgery have the potential to cause serious patient morbidity. Although many of these complications remain uncommon, the range of possible morbidities is wide and includes multiple organ systems. Perioperative visual loss (POVL) is a well described, but uncommon complication that may occur due to ischemia to the optic nerve, retina, or cerebral cortex. Closed-angle glaucoma and amaurosis have been reported as additional etiologies for vision loss following spinal surgery. Peripheral nerve injuries, such as those caused by prolonged traction to the brachial plexus, are more commonly encountered postoperative events. Myocutaneous complications including pressure ulcers and compartment syndrome may also occur after prone positioning, albeit rarely. Other uncommon positioning complications such as tongue swelling resulting in airway compromise, femoral artery ischemia, and avascular necrosis of the femoral head have also been reported. Many of these are well-understood and largely avoidable through thoughtful attention to detail. Other complications, such as POVL, remain incompletely understood and thus more difficult to predict or prevent. Here, the current literature on the complications of prone positioning for spine surgery is reviewed to increase awareness of the spectrum of potential complications and to inform spine surgeons of strategies to minimize the risk of prone patient morbidity.

    Controversy exists regarding the effect of obesity on surgical outcomes and complications following lumbar spinal surgery. A systematic electronic literature review of all relevant studies through to June 2015 was performed using the PubMed, Embase, and Cochrane library databases. Pooled risk ratios (RR) or standardised mean differences (SMD) with 95% confidence intervals (CI) were calculated using random or fixed effects models. The Newcastle-Ottawa Scale was used to evaluate the methodological quality, and Stata 11.0 was used to analyse data (StataCorp, College Station, TX, USA). Significant differences between obese and non-obese patients were found for operation time (SMD, -0.273; 95%CI, -0.424 to -0.121), blood loss (SMD, -0.265; 95%CI, -0.424 to -0.107), surgical site infections (RR, 0.610; 95%CI, 0.446 to 0.834), and nerve injury (RR, 0.188; 95%CI, 0.042 to 0.841). Deep vein thrombosis, dural tear, revision surgery, and mortality were not significantly differences between the two groups (Pinfections and nerve injuries. However, the results of this meta-analysis should be interpreted with caution due to heterogeneity amongst the included studies. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Induced hypotension is widely used intraoperatively to reduce blood loss and to improve the surgical field during spinal surgery. To determine the effect of milrinone on induced hypotension during spinal surgery in elderly patients. Prospective randomized clinical trial. Forty patients, 60 to 70 years old, ASA I-II, who underwent elective lumbar fusion surgery. Intraoperative hemodynamics, blood loss, hourly urine output, and grade of surgical field. All patients were randomized to group M or N. The study drug was infused after perivertebral muscle retraction until complete interbody fusion. In group M, 50 μg/kg/min of milrinone was infused over 10 minutes as a loading dose followed by 0.6 μg/kg/min of milrinone as a continuous dose. In group N, an identical volume of normal saline was infused in the same fashion. This study was not funded by commercial or other sponsorship and the authors confirm no conflicts of interest, financial or otherwise. During infusion of the study drug, the systolic and mean blood pressures were maintained within adequate limits of induced hypotension in group M. Intraoperative blood loss was 445.0±226.5 mL in group M and 765.0±339.2 mL in group N (p=.001). Hourly urine output was 1.4±0.6 mL in group M and 0.8±0.2 mL in group N (pmilrinone is useful for induced hypotension in elderly patients during spinal surgery. Copyright © 2014 Elsevier Inc.

    Despite the many reports attesting to the efficacy of intraoperative somatosensory evoked potential monitoring in reducing the prevalence of iatrogenic spinal cord injury during corrective scoliosis surgery, these afferent neurophysiological signals can provide only indirect evidence of injury to the motor tracts since they monitor posterior column function. Early reports on the use of transcranial electric motor evoked potentials to monitor the corticospinal motor tracts directly suggested that the method holds great promise for improving detection of emerging spinal cord injury. We sought to compare the efficacy of these two methods of monitoring to detect impending iatrogenic neural injury during scoliosis surgery. We reviewed the intraoperative neurophysiological monitoring records of 1121 consecutive patients (834 female and 287 male) with adolescent idiopathic scoliosis (mean age, 13.9 years) treated between 2000 and 2004 at four pediatric spine centers. The same group of experienced surgical neurophysiologists monitored spinal cord function in all patients with use of a standardized multimodality technique with the patient under total intravenous anesthesia. A relevant neurophysiological change (an alert) was defined as a reduction in amplitude (unilateral or bilateral) of at least 50% for somatosensory evoked potentials and at least 65% for transcranial electric motor evoked potentials compared with baseline. Thirty-eight (3.4%) of the 1121 patients had recordings that met the criteria for a relevant signal change (i.e., an alert). Of those thirty-eight patients, seventeen showed suppression of the amplitude of transcranial electric motor evoked potentials in excess of 65% without any evidence of changes in somatosensory evoked potentials. In nine of the thirty-eight patients, the signal change was related to hypotension and was corrected with augmentation of the blood pressure. The remaining twenty-nine patients had an alert that was related directly to a

    Studies have shown that physiopathological changes to the respiratory system can occur following thoracic and abdominal surgery. Laminectomy is considered to be a peripheral surgical procedure, but it is possible that thoracic spinal surgery exerts a greater influence on lung function. The aim of this study was to evaluate the pulmonary volumes and maximum respiratory pressures of patients undergoing cervical, thoracic or lumbar spinal surgery. Prospective study in a tertiary-level university hospital. Sixty-three patients undergoing laminectomy due to diagnoses of tumors or herniated discs were evaluated. Vital capacity, tidal volume, minute ventilation and maximum respiratory pressures were evaluated preoperatively and on the first and second postoperative days. Possible associations between the respiratory variables and the duration of the operation, surgical diagnosis and smoking status were investigated. Vital capacity and maximum inspiratory pressure presented reductions on the first postoperative day (20.9% and 91.6%, respectively) for thoracic surgery (P = 0.01), and maximum expiratory pressure showed reductions on the first postoperative day in cervical surgery patients (15.3%; P = 0.004). The incidence of pulmonary complications was 3.6%. There were reductions in vital capacity and maximum respiratory pressures during the postoperative period in patients undergoing laminectomy. Surgery in the thoracic region was associated with greater reductions in vital capacity and maximum inspiratory pressure, compared with cervical and lumbar surgery. Thus, surgical manipulation of the thoracic region appears to have more influence on pulmonary function and respiratory muscle action.

    The authors report a case of intracranial epidural hemorrhage (ICEH) during spinal surgery. We could not find ICEH, though we recorded transcranial electrical stimulation motor evoked potentials (TcMEPs). A 35-year-old man was referred for left anterior thigh pain and low back pain that hindered sleep. Sagittal T2-weighted magnetic resonance imaging revealed an intradural tumor at L3-L4 vertebral level. We performed osteoplastic laminectomy and en bloc tumor resection. TcMEPs were intraoperatively recorded at the bilateral abductor digiti minimi (ADM), quadriceps, tibialis anterior and abductor hallucis. When we closed a surgical incision, we were able to record normal TcMEPs in all muscles. The patient did not fully wake up from the anesthesia. He had right-sided unilateral positive ankle clonus 15 min after surgery in spite of bilateral negative of ankle clonus preoperatively. Emergent brain computed tomography scans revealed left epidural hemorrhage. The hematoma was evacuated immediately via a partial craniotomy. There was no restriction of the patient's daily activities 22 months postoperatively. We should pay attention to clinical signs such as headache and neurological findgings such as DTR and ankle clonus for patients with durotomy and cerebrospinal fluid (CSF) leakage. Spine surgeons should know that it was difficult to detect ICEH by monitoring with TcMEPs.

    Full Text Available Abstract Introduction Spinal anesthesia is a widely used general purpose anesthesia. However, serious complications, such as intracranial subdural hemorrhage, can rarely occur. Case presentation We report the case of a 73-year-old Japanese woman who had acute onset of intracranial subdural hemorrhage five days after spinal anesthesia for knee arthroscopic surgery. Conclusion This case highlights the need to pay attention to acute intracranial subdural hemorrhage as a complication after spinal anesthesia. If the headache persists even in a supine position or nausea occurs abruptly, computed tomography or magnetic resonance imaging of the brain should be conducted. An intracranial subdural hematoma may have a serious outcome and is an important differential diagnosis for headache after spinal anesthesia.

    The return to work of patients who undergo spinal surgery poses important medical and social challenge. 1) To establish whether patients who undergo spinal stenosis surgery later return to work. 2) To establish the patient's attitude towards employment. 3) To assess the quality of life of the patients and its influence on their attitude to work. The study population consisted of 58 patients aged from 21 to 80 years (the mean age was 52.33±14.12). There were 29 women (50%) and 29 men (50%) in the group. The patients' quality of life was measured by the use of the WHOQOL-BREF instrument. Individual interviews were conducted 3 to 8 months (a mean of 5.72 months ±1.6) after the surgery. 1) Although 13 patients (22.3%) returned to work, 44 (75.9%) did not, these being manual workers of vocational secondary education. 2) Almost half of the patients (27 patients, i.e. 44%) intend to apply for disability pension, 16 patients (27.6%) consider themselves unfit to work, 22 patients (37.9%) do not feel like working again. 3) The quality of life of the patients decreased. Domain scores for the WHOQOL-BREF are transformed to a 0-100 scale. The mean physical health amounted to 60.67 (±16.31), the mean psychological health was 58.78 (±16.01), while the mean social relations with family and friends were 59.91 (±20.69), and the mean environment 59.62 (±12.48). 1) A total of 75% of the patients operated for lumbar spinal stenosis do not return to their preoperative work. Difficulties in returning to work and decreased quality of life are associated with female sex, lower-level education, hard physical work and low income. 2) Physical health, psychological health, social relations and environment decreased to the mean of approximately 60. 3) The quality of life of the patients who did return to work was similar to that of healthy people.

    Quality of life measurements evaluate surgical results from patients' reported outcomes. To assess the impact of spinal deformity treatment using the Scoliosis Research Society-22 questionnaire. SRS-22 data was collected in 545 consecutive patients (425 females-120 males) pre-operatively, 6-, 12- and 24-months post-operatively. Variables included type and age of surgery (mean: 15.14 ± 2.07 years), gender, diagnosis and year of surgery. Age at surgery was divided in: 10-12, 13-15, and 15-19 years. Mean pre-operative SRS-22 scores for the whole group were: function 3.77 ± 0.75; pain 3.7 ± 0.97; self-image 3.14 ± 0.66; mental health 3.86 ± 0.77; total 3.62 ± 0.66. Mean 2-year post-operative scores were: function 4.39 ± 0.42; pain 4.59 ± 0.56; self-image 4.39 ± 0.51; mental health 4.43 ± 0.56; satisfaction 4.81 ± 0.40; total 4.52 ± 0.37 (padolescents.

    Full Text Available Introduction. Adult spinal deformity (ASD surgeries carry significant morbidity, and this has led many surgeons to apply minimally invasive surgery (MIS techniques to reduce the blood loss, infections, and other peri-operative complications. A spectrum of techniques for MIS correction of ASD has thus evolved, most recently the application of percutaneous iliac screws. Methods. Over an 18 months 10 patients with thoracolumbar scoliosis underwent MIS surgery. The mean age was 73 years (70% females. Patients were treated with multi-level facet osteotomies and interbody fusion using expandable cages followed by percutaneous screw fixation. Percutaneous iliac screws were placed bilaterally using the obturator outlet view to target the ischial body. Results. All patients were successfully instrumented without conversion to an open technique. Mean operative time was 302 minutes and the mean blood loss was 480 cc, with no intraoperative complications. A total of 20 screws were placed successfully as judged by CT scanning to confirm no bony violations. Complications included: two asymptomatic medial breaches at T10 and L5, and one patient requiring delayed epidural hematoma evacuation. Conclusions. Percutaneous iliac screws can be placed safely in patients with ASD. This MIS technique allows for successful caudal anchoring to stress-shield the sacrum and L5-S1 fusion site in long-segment constructs.

    To compare the percentage of patients who were able to bypass the postoperative intensive care recovery unit after selective spinal anesthesia with lidocaine-fentanyl versus levobupivacaine-fentanyl for anorectal surgery in jackknife position. Randomized double-blind clinical trial comparing 2 groups of 30 patients classified ASA 1-2. One group received 18 mg of 0.6% lidocaine plus 10 microg of fentanyl while the other group received 3 mg of 0.1% levobupivacaine plus 10 microg of fentanyl. Intraoperative variables were time of start of surgery, maximum extension of sensory blockade, requirement for rescue analgesics, and hemodynamic events. The level of sensory blockade was recorded at 5, 10, and 15 minutes after the start of surgery and at the end of the procedure. The degrees of postoperative motor blockade and proprioception were recorded, as were the results of the Romberg test and whether or not the patient was able to bypass the postoperative recovery unit. Also noted were times of start of ambulation and discharge, complications, and postoperative satisfaction. Intraoperative variables did not differ significantly between groups, and all patients in both groups bypassed the postoperative recovery unit. Times until walking and discharge home, complications, and overall satisfaction after surgery were similar in the 2 groups. Both spinal anesthetic solutions provide effective, selective anesthesia and are associated with similar rates of recovery care unit bypass after anorectal surgery in jackknife position.

    Stainless steel spinal instrumentation has been supplanted in recent years by titanium instrumentation. Knowing whether stainless steel or titanium was used in a previous surgery can guide clinical decision making processes, but frequently the clinician has no way to know what type of metal was used. We describe the radiographic "shadow sign," in which superimposed titanium rods and screws remain radiolucent enough that the contour of the underlying components can be seen on a lateral radiograph, whereas superimposed stainless steel rods and screws are completely radiopaque. This technique was evaluated using a retrospective, randomized, and blinded radiographic comparison of titanium and stainless steel spinal instrumentation. The objective was to determine whether the "shadow sign" can reliably differentiate titanium from stainless steel spinal instrumentation. Lateral radiographs from 16 cases of posterior spinal instrumentation (6 titanium, 6 stainless steel, and 2 replicates of each to assess intraobserver reliability) were randomly selected from a database of cases performed for pediatric scoliosis in a university setting from 2005 to 2009. The cases were randomized then shown to 19 orthopaedic surgery residents, 1 spine fellow, and 2 spine attendings. After the "shadow sign" was described, the surgeons were asked to determine what type of metal each implant was made of. The κ value for both stainless steel and titanium versus the gold standard was 0.83 [standard error (SE) = 0.053], indicating excellent agreement. The κ value for agreement between raters was 0.71 (SE = 0.016) and the κ value for agreement within raters was 0.70 (SE = 0.016), both of which indicated substantial agreement. The "shadow sign" can help a clinician differentiate titanium from stainless steel spinal instrumentation based on radiographic appearance alone. Furthermore, our study reveals that the level of experience in diagnosing spinal lateral radiographs also enhances the use of

    Full Text Available Introduction: In this study, we aimed to compare the spinal anesthesia technique with combined femoral-sciatic block technique in patients undergoing lower limb surgery. Methods: In this study, after obtaining the approval of the Dicle University Faculty of Medicine Ethics Committee, scheduled for elective lower extremity surgery, the ASA 1-2 groups, between the ages of 18-65, 60 patients were enrolled. Study was planned as a prospective, randomized and controlled. Patients were randomly divided into 2 groups as the spinal anesthesia (Group S and combined sciatic-femoral nerve block (Group CSF to be. Results: Demographic data similar between the groups (p> 0.05. The implementation period of the technique was long in the Group CSF compared with in the Group S (p <0.001. Surgery delivery time was shorter in the Group S compared with in the Group CSF (p <0.001. The time of motor block occurrence was longer in the Group CSF compared with in the Group S (p <0.001. The duration of motor block was long in the Group CSF compared with in the Group S (p <0.001. Conclusion: The each of two methods is safe and effective in lower extremity orthopedic surgery, but the application of peripheral nerve block to provide the long-term advantages such as postoperative analgesia and reducing postoperative analgesic consumption.

    Complications of adult spinal deformity surgery are problematic in osteoporotic individuals. We compared outcomes between Japanese patients treated perioperatively with teriparatide vs. low-dose bisphosphonates. Fifty-eight osteoporotic adult Japanese female patients were enrolled and assigned to perioperative teriparatide (33 patients) and bisphosphonate (25 patients) groups in non-blinded fashion. Pre- and post-operative X-ray and computed tomography imaging were used to assess outcome, and rates were compared between the groups and according to age. Pain scores and Oswestry Disability Indices (ODI) were calculated before and 2 years after surgery. Adjacent vertebral fractures and implant failure, fusion failure, and poor pain and ODI outcomes were significantly more common in the bisphosphonates group than the teriparatide group. Perioperative administration of teriparatide is more effective than that of low-dose bisphosphonates in preventing complications and maintaining fusion rates in osteoporotic Japanese females with spinal deformities undergoing surgery.

    Postoperative ileus (POI) is a common complication after spine surgery, with particularly high rates after adult spinal deformity surgery (ASD). Few investigations have been conducted, however, on predictors of POI following ASD. The objective of this investigation was to determine risk factors for POI in patients undergoing ASD. We also sought to determine the association between POI and in-hospital mortality, length of stay, and total charges. Data were obtained from the National/Nationwide Inpatient Sample, years 2010 - 2014. ASD patients aged ≥26 years-old were selected using ICD-9-CM codes. Multiple logistic and linear regression were utilized. In total, 59,410 patients were included in the analysis. 7.4% of patients experienced POI. On adjusted analysis, the following variables were associated with increased risk of POI: male sex (OR 1.43, CI 1.10 - 1.85), anterior surgical approach (OR 1.78, CI 1.22 - 2.60), 9+ levels fused (OR 1.84, CI 1.24 - 2.73), electrolyte disorders (OR 2.70, CI 2.15 - 3.39), and pathologic weight loss (OR 1.94, CI 1.08 - 3.46). POI was associated with significantly longer length of stay (+39%, CI 29% - 51%) and higher total charges (+23%, CI 14% - 31%). Risk factors for POI were identified. Patients suffering from ileus exhibited 2.9 days longer length of stay and ∼$80,000 higher total charges. These results may be applied clinically to identify patients at risk of POI and to consider addressing modifiable risk factors preoperatively. Future studies should be conducted with additional data to develop models capable of accurately predicting and preventing POI. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Introduction: The return to work of patients who undergo spinal surgery poses important medical and social challenge. Objectives: 1 To establish whether patients who undergo spinal stenosis surgery later return to work. 2 To establish the patient's attitude towards employment. 3 To assess the quality of life of the patients and its influence on their attitude to work. Materials and Methods: The study population consisted of 58 patients aged from 21 to 80 years (the mean age was 52.33±14.12. There were 29 women (50% and 29 men (50% in the group. The patients' quality of life was measured by the use of the WHOQOL-BREF instrument. Individual interviews were conducted 3 to 8 months (a mean of 5.72 months ±1.6 after the surgery. Results: 1 Although 13 patients (22.3% returned to work, 44 (75.9% did not, these being manual workers of vocational secondary education. 2 Almost half of the patients (27 patients, i.e. 44% intend to apply for disability pension, 16 patients (27.6% consider themselves unfit to work, 22 patients (37.9% do not feel like working again. 3 The quality of life of the patients decreased. Domain scores for the WHOQOL-BREF are transformed to a 0-100 scale. The mean physical health amounted to 60.67 (±16.31, the mean psychological health was 58.78 (±16.01, while the mean social relations with family and friends were 59.91 (±20.69, and the mean environment 59.62 (±12.48. Conclusions: 1 A total of 75% of the patients operated for lumbar spinal stenosis do not return to their preoperative work. Difficulties in returning to work and decreased quality of life are associated with female sex, lower-level education, hard physical work and low income. 2 Physical health, psychological health, social relations and environment decreased to the mean of approximately 60. 3 The quality of life of the patients who did return to work was similar to that of healthy people.

    Full Text Available OBJECTIVE: Pulmonary embolism (PE is an important complication of major orthopedic surgery. The aim of this study was to evaluate the incidence of venous thromboembolism (VTE and factors influencing the development of VTE in patients undergoing major orthopedic surgery in a university hospital. METHODS: Patients who underwent major orthopedic surgery (hip arthroplasty, knee arthroplasty, or femur fracture repair between February of 2006 and June of 2012 were retrospectively included in the study. The incidences of PE and deep vein thrombosis (DVT were evaluated, as were the factors influencing their development, such as type of operation, age, and comorbidities. RESULTS: We reviewed the medical records of 1,306 patients. The proportions of knee arthroplasty, hip arthroplasty, and femur fracture repair were 63.4%, 29.9%, and 6.7%, respectively. The cumulative incidence of PE and DVT in patients undergoing major orthopedic surgery was 1.99% and 2.22%, respectively. Most of the patients presented with PE and DVT (61.5% and 72.4%, respectively within the first 72 h after surgery. Patients undergoing femur fracture repair, those aged ≥ 65 years, and bedridden patients were at a higher risk for developing VTE. CONCLUSIONS: Our results show that VTE was a significant complication of major orthopedic surgery, despite the use of thromboprophylaxis. Clinicians should be aware of VTE, especially during the perioperative period and in bedridden, elderly patients (≥ 65 years of age.

    Extramedullary hematopoiesis (EMH) refers to hematopoiesis outside of the medulla of the bone. Chronic anemia states such as thalassemia can cause hematopoietic tissue to expand in certain locations. We report a case of spinal cord compression due to recurrent spinal epidural EMH, which was treated with a combination of surgery and radiotherapy. Pakistan has one of the highest incidence and prevalence of thalassemia in the world. We describe published literature on diagnosis and management of such cases. An 18-year-old male presented with bilateral lower limb paresis. He was a known case of homozygous beta thalassemia major. He had undergone surgery for spinal cord compression due to EMH 4 months prior to presentation. Symptom resolution was followed by deterioration 5 days later. He was operated again at our hospital with complete resection of the mass. He underwent local radiotherapy to prevent recurrence. At 2 years follow-up, he showed complete resolution of symptoms. Follow-up imaging demonstrated no residual mass. The possibility of EMH should be considered in every patient with ineffective erythropoiesis as a cause of spinal cord compression. Treatment of such cases is usually done with blood transfusions, which can reduce the hematopoietic drive for EMH. Other options include surgery, hydroxyurea, radiotherapy, or a combination of these on a case to case basis.

    Spinal fusion surgery causes severe postoperative pain, hampering reconvalescense. We investigated the efficacy of patient-controlled epidural analgesia (PCEA) in a prospective, double-blind, randomized, controlled comparison with patient-controlled IV analgesia (PCIA). After lumbar anterior-posterior fusion receiving an epidural catheter intraoperatively, 72 patients were given either PCEA (ropivacaine 0.125% and sufentanil 1.0 microg/mL at 14 mL/h; bolus: 5 mL; lockout time: 15 min) and IV placebo or PCIA (morphine 2.0 mg/mL; bolus: 3 mg; lockout time: 15 min) and epidural placebo. Pain levels (visual analog scale 0-10), functional capabilities (turning in bed, standing, and walking), analgesic consumption, and side effects were evaluated until 72 h after surgery. Fourteen patients were excluded by predetermined criteria, leaving 58 patients for data analysis. Pain levels at rest and during mobilization were significantly lower in the PCEA when compared with that in the PCIA group throughout the study period (P turn in bed was achieved earlier in the PCEA group (P Patients in the PCEA group were significantly more satisfied with pain therapy (P patient satisfaction when compared with PCIA after spinal fusion surgery.

    Full Text Available We present a rare case of spinal epidural hematoma (SEH after thoracolumbar posterior fusion without decompression surgery for a thoracic vertebral fracture. A 42-year-old man was hospitalized for a thoracic vertebral fracture caused by being sandwiched against his back on broken concrete block. Computed tomography revealed a T12 dislocation fracture of AO type B2, multiple bilateral rib fractures, and a right hemopneumothorax. Four days after the injury, in order to promote early orthostasis and to improve respiratory status, we performed thoracolumbar posterior fusion surgery without decompression; the patient had back pain but no neurological deficits. Three hours after surgery, he complained of acute pain and severe weakness of his bilateral lower extremities; with allodynia below the level of his umbilicus, postoperative SEH was diagnosed. We performed immediate revision surgery. After removal of the hematoma, his symptoms improved gradually, and he was discharged ambulatory one month after revision surgery. Through experience of this case, we should strongly consider the possibility of preexisting SEH before surgery, even in patients with no neurological deficits. We should also consider perioperative coagulopathy in patients with multiple trauma, as in this case.

    There are no guidelines for when surgeons should allow patients to return to sports and athletic activities after spinal fusion for adolescent idiopathic scoliosis (AIS). Current recommendations are based on anecdotal reports and a survey performed more than a decade ago in the era of first/second-generation posterior implants. To identify current recommendations for return to sports and athletic activities after surgery for AIS. Questionnaire-based survey. Adolescent idiopathic scoliosis after corrective surgery. Type and time to return to sports. A survey was administered to members of the Spinal Deformity Study Group. The survey consisted of surgeon demographic information, six clinical case scenarios, three different construct types (hooks, pedicle screws, hybrid), and questions regarding the influence of lowest instrumented vertebra (LIV) and postoperative physical therapy. Twenty-three surgeons completed the survey, and respondents were all experienced expert deformity surgeons. Pedicle screw instrumentation allows earlier return to noncontact and contact sports, with most patients allowed to return to running by 3 months, both noncontact and contact sports by 6 months, and collision sports by 12 months postoperatively. For all construct types, approximately 20% never allow return to collision sports, whereas all surgeons allow eventual return to contact and noncontact sports regardless of construct type. In addition to construct type, we found progressively distal LIV resulted in more surgeons never allowing return to collision sports, with 12% for selective thoracic fusion to T12/L1 versus 33% for posterior spinal fusion to L4. Most respondents also did not recommend formal postoperative physical therapy (78%). Of all surgeons surveyed, there was only one reported instrumentation failure/pullout without neurologic deficit after a patient went snowboarding 2 weeks postoperatively. Modern posterior instrumentation allows surgeons to recommend earlier return

    Full Text Available ABSTRACT OBJECTIVE: To identify the characteristics of patients with spinal cord injury (SCI undergoing surgery. METHODS: Previously, 321 patients with SCI were selected. Clinical and socio-demographic variables were collected. RESULTS: A total of 211 patients were submitted to surgery. Fall and injuries in the upper cervical and lumbosacral regions were associated with conservative treatment. Patients with lesions in the lower cervical spine, worse neurological status, and unstable injuries were associated with surgery. Individuals undergoing surgery were associated with complications after treatment. The authors assessed whether age influenced the characteristics of patients submitted to surgery. Subjects with <60 years of age were associated with motorcycle accidents and the morphologies of injury were fracture-dislocation. Elderly individuals were associated to fall, SCI in the lower cervical spine and the morphology of injury was listhesis. Subsequently, the authors analyzed the gender characteristics in these patients. Women who suffered car accidents were associated to surgery. Women were associated with paraparesis and the morphologic diagnosis was fracture-explosion, especially in the thoracolumbar transition and lumbosacral regions. Men who presented traumatic brain injury and thoracic trauma were related to surgery. These individuals had a worse neurological status and were associated to complications. Men and the cervical region were most affected, thereby, these subjects were analyzed separately (n= 92. The presence of complications increased the length of hospital stay. The simultaneous presence of morphological diagnosis, worst neurological status, tetraplegia, sensory, and motor alterations were associated with complications. Pneumonia and chest trauma were associated with mortality. CONCLUSION: These factors enable investments in prevention, rehabilitation, and treatment.

    Spinal surgery presents a challenge for both neurosurgery and orthopaedic surgery. Due to the heterogeneous differentiation potential of mesenchymal stem cells, there is much interest in the treatment of spine surgery. Animal and human trials focussing on the efficacy of mesenchymal stem cells in spinal cord injury, spine fusion and disc degeneration were included in this systematic review. Published articles up to January 2016 from MEDLINE, PubMed and Ovid were used by searching for specific terms. Of the 2595 articles found, 53 met the selection criteria and were included for analysis (16 on spinal cord injury, 28 on intervertebral disc repair and 9 on spinal fusion). Numerous studies reported better results when the mesenchymal stem cells were used in co-culture with other cells or used in scaffolds. Mesenchymal stem cells were also found to have an immune-modulatory role, which can improve surgical outcome. This systematic review suggests that mesenchymal stem cells can be used safely and effectively for these spinal surgery treatments. Whilst, in certain studies, mesenchymal stem cells did not necessarily show improved results from existing treatments, they provide an alternative option. This can reduce morbidity that arises from current surgical treatment. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

    Metastatic epidural spinal cord compression (MESCC) is a disabling consequence of disease progression. Surgery can restore/preserve physical function, improving access to treatments that increase duration of survival; however, advanced patient age may deter oncologists and surgeons from considering surgical management. Evaluate the duration of ambulation and survival in elderly patients following surgical decompression of MESCC. Retrospective file review of a prospective database, under IRB waiver of informed consent, of consecutive patients treated in an academic tertiary care medical center from 8/2008-3/2015. Patients ≥65 years presenting neurological and/or radiological signs of cord compression due to metastatic disease, who underwent surgical decompression. Duration of ambulation and survival. Patients underwent urgent multidisciplinary evaluation and surgery. Ambulation and survival were compared with age, pre- and postoperative neurological (American Spinal Injury Association [ASIA] Impairment Scale [AIS]) and performance status (Karnofsky Performance Status [KPS], and Tokuhashi Score using Kruskal-Wallis and Wilcoxon signed-rank tests, Pearson correlation coefficient, Cox regression model, log rank analysis, and Kaplan Meir analysis. 40 patients were included (21 male, 54%; mean age 74 years, range 65-87). Surgery was performed a mean 3.8 days after onset of motor symptoms. Mean duration of ambulation and survival were 474 (range 0-1662) and 525 days (range 11-1662), respectively; 53% of patients (21/40) survived and 43% (17/40) retained ambulation for ≥1 year. There was no significant relationship between survival and ambulation for patients aged 65-69, 70-79, or 80-89, although Kaplan Meier analysis suggested stratification. There was a significant relationship between duration of ambulation and pre- and postoperative AIS (p=0.0342, p=0.0358, respectively) and postoperative KPS (p=0.0221). Tokuhashi score was not significantly related to duration of

    OBJECTIVE A previous multilevel fusion mass encountered during revision spinal deformity surgery may obscure anatomical landmarks, making instrumentation unworkable or incurring substantial blood loss and operative time. This study introduced a surgical technique of multiple-hook fixation for fixating previous multilevel fusion masses in revision spinal deformity surgeries and then evaluated its outcomes. METHODS Patients with a previous multilevel fusion mass who underwent revision corrective surgery down to the lumbosacral junction were retrospectively studied. Multiple hooks were used to fixate the fusion mass and linked to distal pedicle screws in the lumbosacral-pelvic complex. Radiological and clinical outcomes were evaluated. RESULTS The charts of 8 consecutive patients with spinal deformity were retrospectively reviewed (7 women, 1 man; mean age 56 years). The primary diagnoses included flat-back deformity (6 cases), thoracolumbar kyphoscoliosis (1 case), and lumbar spondylosis secondary to a previous scoliosis fusion (1 case). The mean follow-up duration was 30.1 months. Operations were performed at T3/4-ilium (4 cases), T7-ilium (1 case), T6-S1 (1 case), T12-S1 (1 case), and T9-L5 (1 case). Of 8 patients, 7 had sagittal imbalance preoperatively, and their mean C-7 plumb line improved from 10.8 ± 2.9 cm preoperatively to 5.3 ± 3.6 cm at final follow-up (p = 0.003). The mean lumbar lordosis of these patients at final follow-up was significantly greater than that preoperatively (35.2° ± 12.6° vs 16.8° ± 11.8°, respectively; p = 0.005). Two perioperative complications included osteotomy-related leg weakness in 1 patient and a stitch abscess in another. CONCLUSIONS The multiple-hook technique provides a viable alternative option for fixating a previous multilevel fusion mass in revision spinal deformity surgery.

    Thirty-five patients (ASA II-III) aged 12 to 17 years, diagnosed as having osteogenic sarcoma and Ewing's sarcoma localizing in the femur and tibia, were examined. Surgery was performed as sectoral resection of the affected bone along with knee joint endoprosthesis. Surgical intervention was made under combined spinal and epidural anesthesia (CSEA) with sedation, by using the methods for exact dosing of propofol (6-4 mg/kg x h). During intervention, a child's respiration remains is kept spontaneous with oxygen insufflation through a nasal catheter. CSEA was performed in two-segmental fashion. The epidural space was first catheterized. After administration of a test dose, 0.5% marcaine spinal was injected into dermatomas below the subarachnoidal space, depending on body weight (3.0-4.0 ml). Sensory blockade developed following 3-5 min and lasted 90-120 min, thereafter a local anesthetic (bupivacaine) or its mixture plus promedole was epidurally administered. ??Anesthesia was effective in all cases, motor blockade. During surgery, there was a moderate arterial hypotension that did not require the use of vasopressors. The acid-alkali balance suggested the adequacy of spontaneous respiration. The only significant complication we observed was atony of the bladder that requires its catheterization till the following day. An epidural catheter makes it possible to effect adequate postoperative analgesia.

    Purpose of the study. The delay in diagnosis of spinal tumors is not rare. The chief complaint may include pain, walking disability and spinal or limb deformities. The purpose of our study is to analyze the spinal deformities associated with non osseous intra-spinal tumors, to assess the complications of treatment, and to set out a preventive protocol. Methods. The incidence and pattern of spinal deformity was assessed before tumor treatment and ultimately after laminectomy or osteoplastic laminotomy (or lamino-plasty). Results. Among the 9 cases with preexisting spinal deformity, the curve magnitude increased after laminectomy in 4. A kyphotic, kyphoscoliotic or scoliotic deformity developed in 18 cases after surgery for tumor resection. Among these 18 patients, only one had bad an adequate osteoplastic laminotomy. The treatment of spinal deformities was surgical in 12 cases, and done by either posterior or anterior and posterior combined arthrodesis. Discussion. Spinal deformity may be the main complaint of a patient who has intraspinal tumor. Prevention of post-laminectomy spinal deformity is mandatory, and could be done by osteoplastic laminotomy and the use of a brace during a minimum period of 4 to 6 months after surgery. Conclusion. Diagnosis of intraspinal tumors in children and adolescents should be done early, and lamino-arthrectomy should be replaced by osteoplastic laminotomy. (authors)

    A case report. We report septic shock as postoperative complication following an instrumented posterior spinal arthrodesis on a patient with multiple body piercings. The management of this potentially catastrophic complication and outcome of treatment is been discussed. Body piercing has become increasingly more common because of change in culture or as a fashion statement. This has been associated with local or generalized ill effects including tissue injury, skin and systemic infections, and septic shock. There is no clear guideline pathway regarding removal and reinsertion of body piercings in patients who undergo major surgery. Complications following orthopedic or spinal procedures associated with body piercing have not been reported. We reviewed the medical notes and radiographs of an adolescent patient with Scheuermann kyphosis and multiple body piercings who underwent a posterior spinal arthrodesis and developed septic shock. Septic shock developed on postoperative day 2 after reinsertion of all piercings following the patient's request. The patient became systemically very unwell and required intensive medical management, as well as a total course of antibiotics of 3 months. The piercings remained in situ. She did not develop a wound infection despite the presence of bacteremia and spinal instrumentation. The patient had no new piercings subsequent to her deformity procedure. Two and a half years after spinal surgery she reported no medical problems, had a balanced spine with no loss of kyphosis correction and no evidence of nonunion or recurrence of deformity. The development of septic shock as a result of piercing reinsertion in the postoperative period has not been previously reported. This is an important consideration to prevent potentially life-threatening complications following major spinal surgery.

    A spinal cord subependymoma is an uncommon, indolent, benign spinal cord tumor. It is radiologically similar to a spinal cord ependymoma, but surgical findings and outcomes differ. Gross total resection of the tumor is not always feasible. The present study was done to determine the clinical, radiological and pathological characteristics of spinal cord subependymomas. We retrospectively reviewed the medical records of ten spinal cord subependymoma patients (M : F=4 : 6; median 38 years; range, 21-77) from four institutions. The most common symptoms were sensory changes and/or pain in eight patients, followed by motor weakness in six. The median duration of symptoms was 9.5 months. Preoperative radiological diagnosis was ependymoma in seven and astrocytoma in three. The tumors were located eccentrically in six and were not enhanced in six. Gross total resection of the tumor was achieved in five patients, whereas subtotal or partial resection was inevitable in the other five patients due to a poor dissection plane. Adjuvant radiotherapy was performed in two patients. Neurological deterioration occurred in two patients; transient weakness in one after subtotal resection and permanent weakness after gross total resection in the other. Recurrence or regrowth of the tumor was not observed during the median 31.5 months follow-up period (range, 8-89). Spinal cord subependymoma should be considered when the tumor is located eccentrically and is not dissected easily from the spinal cord. Considering the rather indolent nature of spinal cord subependymomas, subtotal removal without the risk of neurological deficit is another option.

    Spinal metastasis are getting more frequent. This raises the question of pain and neurological complications, which worsen the functional and survival prognosis of this oncological population patients. The surgical treatment must be the most complete as possible: to decompress and stabilize without delaying the management of the oncological disease. Minimal invasive surgery techniques are by definition, less harmful on musculocutaneous plan than opened ones, with a comparable efficiency demonstrated in degenerative and traumatic surgery. So they seem to be applicable and appropriate to this patient population. We detailed different minimal invasive techniques proposed in the management of spinal metastasis. For this, we used our experience developed in degenerative and traumatic pathologies, and we also referred to many authors, establishing a literature review thanks to Pubmed, Embase. Thirty eight articles were selected and allowed us to describe different techniques: percutaneous methods such as vertebro-/kyphoplasty and osteosynthesis, as well as mini-opened surgery, through a posterior or anterior way. We propose a surgical approach using these minimal invasive techniques, first according to the predominant symptom (pain or neurologic failure), then characteristics of the lesions (number, topography, type…) and the deformity degree. Whatever the technique, the main goal is to stabilize and decompress, in order to maintain a good quality of life for these fragile patients, without delaying the medical management of the oncological disease.

    Failed back surgery syndrome is a common clinical entity for which spinal cord stimulation has been found to be an effective mode of analgesia, but with variable success rates. To determine if focal stimulation of the dorsal columns with a transverse tripolar lead might achieve deeper penetration of the electrical stimulus into the spinal cord and therefore provide greater analgesia to the back. Case report. We describe a 42-year-old female with failed back surgery syndrome that had greater back pain than leg pain. The tripolar lead configuration was achieved by placing percutaneously an octapolar lead in the spinal midline followed by 2 adjacent quadripolar leads, advanced to the T7-T10 vertebral bodies. Tripolar stimulation pattern resulted in more than 70% pain relief in this patient during the screening trial, while stimulation of one or 2 electrodes only provided 20% pain relief. After implantation of a permanent tripolar electrode system with a single rechargeable battery, the pain relief was maintained for one year. This is case report describing a case of a patient with chronic low back pain with a diagnosis of failed back surgery syndrome in which transverse tripolar stimulation using an octapolar and 2 quadripolar leads appeared to be beneficial. The transverse tripolar system consists of a central cathode surrounded by anodes, using 3 leads. This arrangement may contribute to maximum dorsal column stimulation with minimal dorsal root stimulation and provide analgesia to the lower back.

    Iatrogenic paraplegia has been accompanying cardiovascular surgery since its beginning. As a result, surgeons have been developing many theories about the exact mechanisms of this devastating complication. Thus, the impact of single arteries that contribute to the spinal perfusion is one of the most discussed subjects in modern surgery. The subsequent decision of reattachment or the permanent disconnection of these intercostal arteries divides the surgical community. On the one hand, the anatomical or vascular approach pleads for the immediate reimplantation to reconstruct the anatomical situation. On the other hand, the decision of the permanent disconnection aims at avoiding stealing phenomenon away from the spinal vascular network. This spinal collateral network can be described as consisting of three components-the intraspinal and two paraspinal compartments-that feed the nutrient arteries of the spinal cord. The exact functional impact of the different compartments of the collateral network remains poorly understood. In this review, the function of the intraspinal compartment in the context of collateral network principle as an immediate emergency backup system is described. The exact structure and architectural principles of the intraspinal compartment are described. The critical parameters with regard to the risk of postoperative spinal cord ischaemia are the number of anterior radiculomedullary arteries (ARMAs) and the distance between them in relation to the longitudinal extent of aortic disease. The paraspinal network as a sleeping reserve is proposed as the long-term backup system. This sleeping reserve has to be activated by arteriogenic stimuli. These are presented briefly, and prior findings regarding arteriogenesis are discussed in the light of the collateral network concept. Finally, the role of preoperative visualization of the ARMAs in order to evaluate the risk of postoperative paraplegia is emphasized.

  16. What is the role of autologous blood transfusion in major spine surgery?

    Major spine surgery is associated with significant blood loss, which has numerous complications. Blood loss is therefore an important concern when undertaking any major spine surgery. Blood loss can be addressed by reducing intraoperative blood loss and replenishing perioperative blood loss. Reducing intraoperative blood loss helps maintain hemodynamic equilibrium and provides a clearer operative field during surgery. Homologous blood transfusion is still the mainstay for replenishing blood loss in major spine surgery across the world, despite its known adverse effects. These significant adverse effects can be seen in up to 20% of patients. Autologous blood transfusion avoids the risks associated with homologous blood transfusion and has been shown to be cost-effective. This article reviews the different methods of autologous transfusion and focuses on the use of intraoperative cell salvage in major spine surgery. Autologous blood transfusion is a proven alternative to homologous transfusion in major spine surgery, avoiding most, if not all of these adverse effects. However, autologous blood transfusion rates in major spine surgery remain low across the world. Autologous blood transfusion may obviate the need for homologous transfusion completely. We encourage spine surgeons to consider autologous blood transfusion wherever feasible.

    This retrospective case control study aimed to evaluate the feasibility of using Estimation of Physiological Ability and Surgical Stress (E-PASS) and Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) systems in patients undergoing spinal surgical procedures. Degenerative spine disease has increased in incidence in aging societies, as has the number of older adult patients undergoing spinal surgery. Many older adults are at a high surgical risk because of comorbidity and poor general health. We retrospectively reviewed 217 patients who had undergone spinal surgery at a single tertiary care. We investigated complications within 1 month after surgery. Criteria for both skin incision in E-PASS and operation magnitude in the POSSUM system were modified to fit spine surgery. We calculated the E-PASS and POSSUM scores for enrolled patients, and investigated the relationship between postoperative complications and both surgical risk scoring systems. To reinforce the predictive ability of the E-PASS system, we adjusted equations and developed modified E-PASS systems. The overall complication rate for spinal surgery was 22.6%. Forty-nine patients experienced 58 postoperative complications. Nineteen major complications, including hematoma, deep infection, pleural effusion, progression of weakness, pulmonary edema, esophageal injury, myocardial infarction, pneumonia, reoperation, renal failure, sepsis, and death, occurred in 17 patients. The area under the receiver operating characteristic curve (AUC) for predicted postoperative complications after spine surgery was 0.588 for E-PASS and 0.721 for POSSUM. For predicted major postoperative complications, the AUC increased to 0.619 for E-PASS and 0.842 for POSSUM. The AUC of the E-PASS system increased from 0.588 to 0.694 with the Modified E-PASS equation. The POSSUM system may be more useful than the E-PASS system for estimating postoperative surgical risk in patients undergoing

    Full Text Available Background and Aims: Rapid recovery is desirable after neurosurgery as it enables early post-operative neurological evaluation and prompt management of complications. Studies have been rare comparing the recovery characteristics in paediatric neurosurgical patients. Hence, this study was carried out to compare the effect of sevoflurane and desflurane anaesthesia on emergence and extubation in children undergoing spinal surgery. Methods: Sixty children, aged 1-12 years, undergoing elective surgery for lumbo-sacral spinal dysraphism were enrolled. Anaesthesia was induced with sevoflurane using a face mask. The children were then randomised to receive either sevoflurane or desflurane with oxygen and nitrous oxide, fentanyl (1 μg/kg/h and rocuronium. The anaesthetic depth was guided by bispectral index (BIS ® monitoring with a target BIS ® between 45 and 55. Perioperative data with regard to demographic profile, haemodynamics, emergence and extubation times, modified Aldrete score (MAS, pain (objective pain score, agitation (Cole′s agitation score, time to first analgesic and complications, thereof, were recorded. Statistical analysis was done using STATA 11.2 (StataCorp., College Station, TX, USA and data are presented as median (range or mean ± standard deviation. Results: The demographic profile, haemodynamics, MAS, pain and agitation scores and time to first analgesic were comparable in between the two groups (P > 0.05. The emergence time was shorter in desflurane group (2.75 [0.85-12] min as compared to sevoflurane (8 [2.5-14] min (P < 0.0001. The extubation time was also shorter in desflurane group (3 [0.8-10] min as compared to the sevoflurane group (5.5 [1.2-14] min (P = 0.0003. Conclusion: Desflurane provided earlier tracheal extubation and emergence as compared to sevoflurane in children undergoing surgery for lumbo-sacral spinal dysraphism.

    Twenty adult male patients undergoing anorectal surgery in the jackknife position under spinal anaesthesia were studied for the anaesthetic properties of 5 ml hypobaric 0.1% bupivacaine. The patients were positioned in the prone, jack-knife position with a pillow under the hips and with an operating table break angulation of 30 degrees with head down tilt of 20 degrees. In this position a 25-gauge Quincke spinal needle was inserted intrathecally through L3-4 and 5 ml solution, prepared by mixing 1 ml bupivacaine 0.5% with 4 ml of distilled water with a specific gravity of 1.001 at 20 degrees C, was given over 15-20 sec. Onset time, progression and upper level of sensory blockade evaluated by pin prick, and the extent of motor block (1 = full motor movement at ankle and knee joint, 2 = restricted motor movements, 3 = full motor block, no movements) were measured at one minute intervals for the first five minutes, then every five minutes for 30 min. The number of dermatomes blocked was also noted. The median level of cephalad sensory blockage was of L1, with a range from T10-L3. On average, nine dermatomes were blocked (range 7-12). Motor blockade was not observed in any patient. Changes in heart rate and blood pressure were minimal. The average duration of postoperative analgesia was 339.5 +/- 182.9 min. Post-spinal headache was not observed in any patients. In conclusion, 5 ml intrathecal hypobaric bupivacaine, 0.1%, provided excellent perioperative analgesia without motor blockade and haemodynamic stability in patients undergoing anorectal surgery in jackknife position.

    A pilot study was performed in patients with recurrent back pain after spinal fusion surgery to evaluate the ability of 18 F-NaF PET/CT imaging to correctly identify those requiring surgical intervention and to locate a site amenable to surgical intervention. In this prospective study 22 patients with recurrent back pain after spinal surgery and with equivocal findings on physical examination and CT were enrolled for evaluation with 18 F-NaF PET/CT. All PET/CT images were prospectively reviewed with the primary objective of identifying or ruling out the presence of lesions amenable to surgical intervention. The PET/CT results were then validated during surgical exploration or clinical follow-up of at least 15 months. Abnormal 18 F-NaF foci were found in 16 of the 22 patients, and surgical intervention was recommended. These foci were located at various sites: screws, cages, rods, fixation hardware, and bone grafts. In 6 of the 22 patients no foci requiring surgical intervention were found. Validation of the results by surgery (15 patients) or on clinical follow-up (7 patients) showed that 18 F-NaF PET/CT correctly predicted the presence of an abnormality requiring surgical intervention in 15 of 16 patients and was falsely positive in 1 of 16. In this initial investigation, 18 F-NaF PET/CT imaging showed potential utility for evaluation of recurrent symptoms after spinal fusion surgery by identifying those patients requiring surgical management.

    Spinal instrumentation has a high rate of surgical site infection (SSI), but results greatly vary depending on surveillance methodology, surgical procedures, or quality of follow-up. Our aim was to study true incidence of SSI in spinal surgery by significant data collection, and to compare it with the results obtained through the hospital information system. This work is a single center prospective cohort study that included all patients consecutively operated on for spinal instrumentation by posterior approach over a six-month period regardless the etiology. For all patients, a "high definition" prospective method of surveillance was performed by the infection control (IC) department during at least 12 months after surgery. Results were then compared with findings from automatic surveillance though the hospital information system (HIS). One hundred and fifty-four patients were included. We found no hardly difference between "high definition" and automatic surveillance through the HIS, even if HIS tended to under-estimate the infection rate: rate of surgical site infection was 2.60% and gross SSI incidence rate via the hospital information system was 1.95%. Smoking and alcohol consumption were significantly related to a SSI. Our SSI rates to reflect the true incidence of infectious complications in posterior instrumented adult spinal surgery in our hospital and these results were consistent with the lower levels of published infection rate. In-house surveillance by surgeons only is insufficiently sensitive. Further studies with more patients and a longer inclusion time are needed to conclude if SSI case detection through the HIS could be a relevant and effective alternative method.

    Full Text Available Purpose. Control of persistent pain following spinal surgery is an unmet clinical need. This study compared the efficacy and safety of buprenorphine transdermal system (BTDS to oral tramadol/acetaminophen (TA in Korean patients with persistent, moderate pain following spinal surgery. Methods. Open-label, interventional, randomized multicenter study. Adults with persistent postoperative pain (Numeric Rating Scale [NRS] ≥ 4 at 14–90 days postsurgery were enrolled. Patients received once-weekly BTDS (n=47; 5 μg/h titrated to 20 μg/h or twice-daily TA (n=40; tramadol 37.5 mg/acetaminophen 325 mg, one tablet titrated to 4 tablets for 6 weeks. The study compared pain reduction with BTDS versus TA at week 6. Quality of life (QoL, treatment satisfaction, medication compliance, and adverse events (AEs were assessed. Findings. At week 6, both groups reported significant pain reduction (mean NRS change: BTDS −2.02; TA −2.76, both P<0.0001 and improved QoL (mean EQ-5D index change: BTDS 0.10; TA 0.19, both P<0.05. The BTDS group achieved better medication compliance (97.8% versus 91.0%. Incidence of AEs (26.1% versus 20.0% and adverse drug reactions (20.3% versus 16.9% were comparable between groups. Implications. For patients with persistent pain following spinal surgery, BTDS is an alternative to TA for reducing pain and supports medication compliance.

    The O-arm ® navigation system allows intraoperative CT imaging that can facilitate highly accurate instrumentation surgery, but radiation exposure is higher than with X-ray radiography. This is a particular concern in pediatric surgery. The purpose of this study is to examine intraoperative radiation exposure in pediatric spinal scoliosis surgery using O-arm. The subjects were 38 consecutive patients (mean age 12.9 years, range 10-17) with scoliosis who underwent spinal surgery with posterior instrumentation using O-arm. The mean number of fused vertebral levels was 11.0 (6-15). O-arm was performed before and after screw insertion, using an original protocol for the cervical, thoracic, and lumbar spine doses. The average scanning range was 6.9 (5-9) intervertebral levels per scan, with 2-7 scans per patient (mean 4.0 scans). Using O-arm, the dose per scan was 92.5 (44-130) mGy, and the mean total dose was 401 (170-826) mGy. This dose was 80.2% of the mean preoperative CT dose of 460 (231-736) mGy (P = 0.11). The total exposure dose and number of scans using intraoperative O-arm correlated strongly and significantly with the number of fused levels; however, there was no correlation with the patient's height. As the fused range became wider, several scans were required for O-arm, and the total radiation exposure became roughly the same as that in preoperative CT. Use of O-arm in our original protocol can contribute to reduction in radiation exposure.

    The achondroplastic spinal canal is narrow due to short pedicles and a small interpedicular distance. Compression of neural structures passing through this canal is therefore regularly encountered but rarely described. Symptomatology, radiological evaluation, and treatment of 20 patients with achondroplasia who underwent decompression of the thoracic spinal cord are described and outcome is correlated with the size of the spinal canal and the thoracolumbar kyphotic angle. Scores from the modified Japanese Orthopaedic Association scale, Nurick scale, European Myelopathy scale, Cooper myelopathy scale for lower extremities, and Odom criteria before and after surgery were compared. Magnetic resonance imaging was evaluated to determine the size of the spinal canal, spinal cord compression, and presence of myelomalacia. The thoracolumbar kyphotic angle was measured using fluoroscopy. Patient symptomatology included deterioration of walking pattern, pain, cramps, spasms, and incontinence. Magnetic resonance images of all patients demonstrated spinal cord compression due to degenerative changes. Surgery resulted in a slight improvement on all the ranking scales. Surgery at the wrong level occurred in 15% of cases, but no serious complications occurred. The mean thoracolumbar kyphotic angle was 20°, and no correlation was established between this angle and outcome after surgery. No postoperative increase in this angle was reported. There was also no correlation between size of the spinal canal and outcome. Decompressive surgery of the thoracic spinal cord in patients with achondroplasia can be performed safely if anatomical details are taken into consideration. Spondylodesis did not appear essential. Special attention should be given to the method of surgery, identification of the level of interest, and follow-up of the thoracolumbar kyphotic angle.

    Patients receiving lumbar spinal fusion surgery often have persisting postoperative pain negatively affecting their daily life. These patients may be helped by interdisciplinary cognitive-behavioral therapy which is recognized as an effective intervention for improving beneficial pain coping behavior, thereby facilitating the rehabilitation process of patients with chronic pain. The purpose of this study was to describe the lived experience of patients recovering from lumbar spinal fusion surgery and to explore potential similarities and disparities in pain coping behavior between receivers and nonreceivers of interdisciplinary cognitive-behavioral group therapy. We conducted semistructured interviews with 10 patients; 5 receiving cognitive-behavioral therapy in connection with their lumbar spinal fusion surgery and 5 receiving usual care. We conducted a phenomenological analysis to reach our first aim and then conducted a comparative content analysis to reach our second aim. Patients' postoperative experience was characterized by the need to adapt to the limitations imposed by back discomfort (coexisting with the back), need for recognition and support from others regarding their pain, a relatively long rehabilitation period during which they "awaited the result of surgery", and ambivalence toward analgesics. The patients in both groups had similar negative perception of analgesics and tended to abstain from them to avoid addiction. Coping behavior apparently differed among receivers and nonreceivers of interdisciplinary cognitive-behavioral group therapy. Receivers prevented or minimized pain by resting before pain onset, whereas nonreceivers awaited pain onset before resting. The postoperative experience entailed ambivalence, causing uncertainty, worry and insecurity. This ambivalence was relieved when others recognized the patient's pain and offered support. Cognitive-behavioral therapy as part of rehabilitation may have encouraged beneficial pain coping

    Spinal fusion for idiopathic scoliosis is one of the most painful surgeries experienced by adolescents. Music therapy, utilizing music-assisted relaxation with controlled breathing and imagery, is a promising intervention for reducing pain and anxiety for these patients. It can be challenging to teach new coping strategies to post-operative patients who are already in pain. This study evaluated the effects of introducing music-assisted relaxation training to adolescents before surgery. Outcome measures were self-reported pain and anxiety, recorded on 0-10 numeric rating scale, and observed behavioral indicators of pain and relaxation. The training intervention was a 12-minute video about music-assisted relaxation with opportunities to practice before surgery. Forty-four participants between the ages of 10 and 19 were enrolled. Participants were randomly assigned to the experimental group that watched the video at the preoperative visit or to the control group that did not watch the video. All subjects received a music therapy session with a board certified music therapist on post-operative day 2 while out of bed for the first time. Pain and anxiety were significantly reduced from immediately pre-therapy to post-therapy (paired t-test; p). Copyright © 2016 American Society for Pain Management Nursing. Published by Elsevier Inc.

    The general radiologist frequently encounters studies demonstrating spinal instrumentation, either as part of the patient's postoperative evaluation or as incidental to a study performed for another purpose. There are various surgical approaches and devices used in spinal surgery with an increased understanding of spinal and spinal implant biomechanics drives development of modern fixation devices. It is, therefore, important that the radiologist can recognize commonly used devices and identify their potential complications demonstrated on imaging. The aim of part 1 of this review is to familiarize the reader with terms used to describe surgical approaches to the spine, review the function and normal appearances of commonly used instrumentations, and understand the importance of the different fixation techniques. The second part of this review will concentrate on the roles that the different imaging techniques play in assessing the instrumented spine and the recognition of complications that can potentially occur.

    During thoracoabdominal surgery in which segmental arteries are sacrificed over a large area, blood supply routes from collateral networks have received attention as a means of avoiding spinal cord injury. The aim of this study was to investigate spinal cord blood supply through a collateral network by directly measuring spinal cord blood flow and spinal cord perfusion pressure experimentally. In beagle dogs (n = 8), the thoracoabdominal aorta and segmental arteries L1-L7 were exposed, and a temporary bypass was created for distal perfusion. Next, a laser blood flow meter was placed on the spinal dura mater in the L5 region to measure the spinal cord blood flow. The following were measured simultaneously when the direct blood supply from segmental arteries L2-L7 to the spinal cord was stopped: mean systemic blood pressure, spinal cord perfusion pressure (blood pressure within the aortic clamp site), and spinal cord blood flow supplied via the collateral network. These variables were then investigated for evidence of correlations. Positive correlations were observed between mean systemic blood pressure and spinal cord blood flow during interruption of segmental artery flow both with (r = 0.844, P flow with and without distal perfusion (r = 0.803, P network from outside the interrupted segmental arteries, and high systemic blood pressure (∼1.33-fold higher) was needed to obtain the preclamping spinal cord blood flow, whereas 1.68-fold higher systemic blood pressure was needed when distal perfusion was halted. Spinal cord blood flow is positively correlated with mean systemic blood pressure and spinal cord perfusion pressure under spinal cord ischemia caused by clamping a wide range of segmental arteries. In open and endovascular thoracic and thoracoabdominal surgery, elevating mean systemic blood pressure is a simple and effective means of increasing spinal cord blood flow, and measuring spinal cord perfusion pressure seems to be useful for monitoring

    Prospective multicenter study of adult spinal deformity (ASD) surgery. To clarify the effect of ASD surgery on each health-related quality of life (HRQOL) subclass/domain. For patients with ASD, surgery offers superior radiological and HRQOL outcomes compared with nonoperative care. HRQOL may, however, be affected by surgical advantages related to corrective effects, yielding adequate spinopelvic alignment and stability or disadvantages because of long segment fusion. The study included 170 consecutive patients with ASD from a multicenter database with more than 2-year follow-up period. We analyzed each HRQOL domain/subclass (short form-36 items, Oswestry Disability Index, Scoliosis Research Society-22 [SRS-22] questionnaire), and radiographic parameters preoperatively and at 1 and 2 years postoperatively. We divided the patients into two groups each based on lowest instrumented vertebra (LIV; above L5 or S1 to ilium) or surgeon-determined preoperative pathology (idiopathic or degenerative). Improvement rate (%) was calculated as follows: 100 × |pre.-post.|/preoperative points (%) (+, advantages; -, disadvantages). The scores of all short form-36 items and SRS-22 subclasses improved at 1 and 2 years after surgery, regardless of LIV location and preoperative pathology. Personal care and lifting in Oswestry Disability Index were, however, not improved after 1 year. These disadvantages were correlated to sagittal modifiers of SRS-Schwab classification similar to other HRQOL. The degree of personal care disadvantage mainly depended on LIV location and preoperative pathology. Although personal care improved after 2 years postoperatively, no noticeable improvements in lifting were recorded. HRQOL subclass analysis indicated two disadvantages of ASD surgery, which were correlated to sagittal radiographic measures. Fusion to the sacrum or ilium greatly restricted the ability to stretch or bend, leading to limited daily activities for at least 1 year postoperatively

  14. Approaches to radiotherapy in metastatic spinal cord compression.

    Metastatic spinal cord compression is caused by the progression of metastatic lesions within the vicinity of the spinal cord. The consequences are very severe with loss of neurological function and severe pain. The standard treatment is surgical intervention followed by radiotherapy or radiotherapy alone. However, the majority of patients are treated with radiotherapy only due to contraindications to surgery and technical inoperability. Stereotactic body radiotherapy is a technology to deliver higher radiation dose to the radiotherapy target with the use of spatial coordinates. This modality has shown positive results in treating lesions in brain and lungs. Hence, it could prove beneficial in metastatic spinal cord compression. We designed and planned a trial to investigate this method in patients with metastatic spinal cord compression. The method was usable but the trial was stopped prematurely due to low accrual that made comparison with surgery impossible. Low accrual is a known problem for trials evaluating new approaches in radiotherapy. Target definition in radiotherapy of metastatic spinal cord compression is defined by patient history, examination and imaging. Functional imaging could provide information to guide target definition with the sparring of normal tissue e.g. spinal cord and hematopoietic tissue of the bone marrow. In future trials this may be used for dose escalation of spinal metastases. The trial showed that PET/MRI was feasible in this group of patients but did not change the radiotherapy target in the included patients. Neurological outcome is similar irrespective of course length and therefore single fraction radiotherapy is recommended for the majority of patients. In-field recurrence is a risk factor of both short and long fractionation schemes and re-irradiation have the potential risk of radiation-induced myelopathy. In a retrospective study of re-irradiation, we investigated the incidence of radiation-induced myelopathy. In our study

    To determine the suitability of amniotic membrane an bovine bone xenografts for the use in spinal surgery and anterior cranial for a generations. Fifteen patients with anterior cranial fossa defects and spinal bone fractures received bovine bone xenografts and 10 patients with meningomyeloceles received amniotic membranes (produced by the Malaysian National Tissue Bank) were analysed retrospectively. Clinical criterias like fever, signs of inflammation, breakdown of graft implant, non specific reaction to the nervous tissue were analysed haematological and radiologically. All patients who received the bovine grafts and amniotic membranes did not show any evidence of inflammation or fever. There were no graft implant breakdowns. There was no radiological or clinical evidence of specific or non specific reaction to the nervous tissue after 12-36 months followup Amniotic membranes and bovine xenografts may be used in the healing and reconstruction of spinal and cranial defects. Despite no evidence of rejection and infection after 36 months, a long term followup is still needed

    Cysticercosis usually affects the brain and is easily demonstrated by CT. Spinal cysticercosis is much rarer and is usually diagnosed only at surgery. Myelographic demonstration of multiple rounded filling defects, some of which were mobile, allowed diagnosis of spinal extramedullary cysticercosis in an unsuspected case. The literature on spinal cysticercosis is briefly reviewed. Diagnosis is important in view of the recent development of medical treatment.

  18. Back pain in patients with degenerative spine disease and intradural spinal tumor: what to treat? when to treat?

    Back pain is common in industrialized countries and one of the most frequent causes of work incapacity. Successful treatment is, therefore, not only important for improving the symptoms and the quality of life of these patients but also for socioeconomic reasons. Back pain is frequently caused by degenerative spine disease. Intradural spinal tumors are rare with an annual incidence of 2-4/1,00,000 and are mostly associated with neurological deficits and radicular and nocturnal pain. Back pain is not commonly described as a concomitant symptom, such that in patients with both a tumor and degenerative spine disease, any back pain is typically attributed to the degeneration rather than the tumor. The aim of the present retrospective investigation was to study and analyze the impact of microsurgery on back/neck pain in patients with intradural spinal tumor in the presence of degenerative spinal disease in adjacent spinal segments. Fifty-eight consecutive patients underwent microsurgical, intradural tumor surgery using a standardized protocol assisted by multimodal intraoperative neuromonitoring. Clinical symptoms, complications and surgery characteristics were documented. Standardized questionnaires were used to measure outcome from the surgeon's and the patient's perspectives (Spine Tango Registry and Core Outcome Measures Index). Follow-up included clinical and neuroradiological examinations 6 weeks, 3 months and 1 year postoperatively. Back/neck pain as a leading symptom and coexisting degenerative spine disease was present in 27/58 (47 %) of the tumor patients, and these comprised to group under study. Patients underwent tumor surgery only, without addressing the degenerative spinal disease. Remission rate after tumor removal was 85 %. There were no major surgical complications. Back/neck pain as the leading symptom was eradicated in 67 % of patients. There were 7 % of patients who required further invasive therapy for their degenerative spinal disease. Intradural

    OBJECT The aim of this study was to evaluate outcome in patients undergoing surgical treatment for intradural spinal tumor using a patient-oriented, self-rated, outcome instrument and a physician-based disease-specific instrument. METHODS Prospectively collected data from 63 patients with intradural spinal tumor were analyzed in relation to scores on the multidimensional patient-rated Core Outcome Measures Index (COMI) and the physician-rated modified McCormick Scale, before and at 3 and 12 months after surgery. RESULTS There was no statistically significant difference between the scores on the modified McCormick Scale preoperatively and at the 3-month follow-up, though there was a trend for improvement (p = 0.073); however, comparisons between the scores determined preoperatively and at the 12-month follow-up, as well as 3- versus 12-month follow-ups, showed a statistically significant improvement in each case (p 0.05) up to 12 months postoperatively. In contrast, the overall COMI score, "worst pain," quality of life, and social disability not only showed a significant reduction from before surgery to 3 months after surgery (p 0.05), but did show a significant improvement (p = 0.011) from 3 months to 12 months after surgery. At the 3- and 12-month follow-ups, 85.2% and 83.9% of patients, respectively, declared that the surgical procedure had helped/helped a lot; 95.1% and 95.2%, respectively, declared that they were satisfied/very satisfied with their care. CONCLUSIONS COMI is a feasible tool to use in the evaluation of baseline symptoms and outcome in patients undergoing surgery for intradural spinal tumor. COMI was able to detect changes in outcome at 3 months after surgery (before changes were apparent on the modified McCormick Scale) and on later postoperative follow-up. The COMI subdomains are valuable for monitoring the patient's reintegration into society and the work environment. The addition of an item that specifically covers neurological deficits may

    A retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database, a national representative database in Japan. The aim of this study was to examine seasonal variations in the risk of reoperation for surgical site infection (SSI) following spinal fusion surgery. Although higher rates of infection in the summer than in other seasons were thought to be caused by increasing inexperience of new staff, high temperature, and high humidity, no studies have examined seasonal variations in the risk of SSI following spinal fusion surgery in the country where medical staff rotation timing is not in summer season. In Japan, medical staff rotation starts in April. We retrospectively extracted the data of patients who were admitted between July 2010 and March 2013 from the DPC database. Patients were included if they were aged 20 years or older and underwent elective spinal fusion surgery. The primary outcome was reoperation for SSI during hospitalization. We performed multivariate analysis to clarify the risk factors of primary outcome with adjustment for patient background characteristics. We identified 47,252 eligible patients (23,659 male, 23,593 female). The mean age of the patients was 65.4 years (range, 20-101 yrs). Overall, reoperation for SSI occurred in 0.93% of the patients during hospitalization. The risk of reoperation for SSI was significantly higher in April (vs. February; odds ratio, 1.93; 95% confidence interval, 1.09-3.43, P = 0.03) as well as other known risk factors. In subgroup analysis with stratification for type of hospital, month of surgery was identified as an independent risk factor of reoperation for SSI among cases in an academic hospital, although there was no seasonal variation among those in a nonacademic hospital. This study showed that month of surgery is a risk factor of reoperation for SSI following elective spinal fusion surgery, nevertheless, in the country where medical staff rotation timing is not in

    Spinal angiolipomas are fairly infrequent benign tumours that are usually located in the epidural space of the thoracic column and represent 0.14% to 1.3% of all spinal tumours. Lumbar angiolipomas are extremely rare, representing only 9.6% of all spinal extradural angiolipomas. We report the case of a woman who complained of a lumbar pain of several months duration with no neurological focality and that had intensified in the last three days without her having had any injury or made a physical effort. The MR revealed an extradural mass L1-L2, on the posterior face of the medulla, decreasing the anteroposterior diameter of the canal. The patient symptoms improved after surgery. Total extirpation of the lesion is possible in most cases, and the prognosis is excellent even if the lesion is infiltrative. For this reason, excessively aggressive surgery is not necessary to obtain complete resection. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    2017-01-01

    Full Text Available Introduction: Lumbar decompressions and micro-discectomies are commonly performed non-complex spinal surgeries that do not involve the insertion of metalwork into the spine and are done for symptomatic disc prolapse and lumbar spinal stenosis, whereas complex-spinal surgery does require metalwork [1]. Studies of complex-spinal surgeries show that smoking has a significant negative impact on the outcome of the surgery [2] therefore, the cessation of smoking is advised prior to surgery [3]. There are evidences in the literature supportive as well as opposing this statement about continued smoking and poor outcome of decompressive spinal surgeries. Methods: We retrospectively reviewed 143 consecutive patients who have had either a micro-discectomy or a micro-decompression. Results: We found no statistical difference between smokers and non-smokers in the outcomes of lumbar decompression surgery. Both groups improved equally and significantly in terms of back pain, leg pain and functions. Out of 143 patients, only 2% more non-smokers had improved leg pain compared to smokers, 1% less non-smokers had improved back pain and 2% more non-smokers had an improved Oswestry Disability Index (ODI score. Discussion: We recommend that it is important to surgically treat both smokers and non-smokers in need of a lumbar spinal decompression.

    The increasing subspecialisation of general surgeons in their elective work may result in problems for the provision of expert care for emergency cases. There is very little evidence of the impact of subspecialism on outcomes following emergency major upper gastrointestinal surgery. This prospective study investigated whether elective subspecialism of general surgeon is associated with a difference in outcome following major emergency gastric surgery. Between February 1994 and June 2010, the data from all emergency major gastric procedures (defined as patients who underwent laparotomy within 12 hours of referral to the surgical service for bleeding gastroduodenal ulcer and/or undergoing major gastric resection) was prospectively recorded. The sub-specialty interest of operating surgeon was noted and related to post-operative outcomes. Over the study period, a total of 63 major gastric procedures were performed of which 23 (37%) were performed by specialist upper gastrointestinal (UGI) consultants. Surgery performed by a specialist UGI surgeon was associated with a significantly lower surgical complication (4% vs. 28% of cases; p=0.04) and in-patient mortality rate (22% vs. 50%; p=0.03). Major emergency gastric surgery has significantly better clinical outcomes when performed by a specialist UGI surgeon. These results have important implications for provision of an emergency general surgical service. Copyright© Acta Chirurgica Belgica.

    Postoperative urinary retention (POUR) is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%), 3 patients in Group II (5%) and 4 patients in Group III (6.7%) required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006). The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697). This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

    It is widely believed that the choice between isobaric bupivacaine and hyperbaric bupivacaine formulations alters the block characteristics for the conduct of surgery under spinal anesthesia. The aim of this study was to systematically review the comparative evidence regarding the effectiveness and safety of the 2 formulations when used for spinal anesthesia for adult noncesarean delivery surgery. Key electronic databases were searched for randomized controlled trials, excluding cesarean delivery surgeries under spinal anesthesia, without any language or date restrictions. The primary outcome measure for this review was the failure of spinal anesthesia. Two independent reviewers selected the studies and extracted the data. Results were expressed as relative risk (RR) or mean differences (MDs) with 95% confidence intervals (CIs). Seven hundred fifty-one studies were identified between 1946 and 2016. After screening, there were 16 randomized controlled clinical trials, including 724 participants, that provided data for the meta-analysis. The methodological reporting of most studies was poor, and appropriate judgment of their individual risk of bias elements was not possible. There was no difference between the 2 drugs regarding the need for conversion to general anesthesia (RR, 0.60; 95% CI, 0.08-4.41; P = .62; I = 0%), incidence of hypotension (RR, 1.15; 95% CI, 0.69-1.92; P = .58; I = 0%), nausea/vomiting (RR, 0.29; 95% CI, 0.06-1.32; P = .11; I = 7%), or onset of sensory block (MD = 1.7 minutes; 95% CI, -3.5 to 0.1; P = .07; I = 0%). The onset of motor block (MD = 4.6 minutes; 95% CI, 7.5-1.7; P = .002; I = 78%) was significantly faster with hyperbaric bupivacaine. Conversely, the duration of motor (MD = 45.2 minutes; 95% CI, 66.3-24.2; P bupivacaine. Both hyperbaric bupivacaine and isobaric bupivacaine provided effective anesthesia with no difference in the failure rate or adverse effects. The hyperbaric formulation allows for a relatively rapid motor block onset

    We report a case of a thalassemia major male patient with back pain associated to severe weakness in lower extremities resulting in the ability to ambulate only with assistance. An urgent magnetic resonance imaging (MRI) of  thoracic and lumbosacral spine was requested. A posterior intraspinal extradural mass lesion compressing the spinal cord at the level of thoracic T5-8 was present, suggesting an extramedullary hematopoietic centre, compressing the spinal cord. He was treated successfully with thalassemia major alone. The patient was treated with blood transfusion, dexamethasone, morphine and paracetamol, followed by radiotherapy in 10 fractions to the spine (daily fraction of 2Gy from T3 to T9, total dose 20 Gy). His pain and neurologic examination quickly improved. A new MRI of the spine, one week after radiotherapy, showed an improvement of the extramedullary hematopoietic mass compression. In conclusion, EMH should be considered in every patient with ineffective erythropoiesis and spinal cord symptoms. MRI is the most effective method of demonstrating EMH. The rapid recognition and treatment can dramatically alleviate symptoms. There is still considerable controversy regarding indications, benefits, and risks of each of modality of treatment due to the infrequency of this disorder.

    Extraparenchymal spinal cord hematoma has been described in veterinary medicine in association with neoplasia, intervertebral disk disease, and snake envenomation. There are rare reports of spontaneous extraparenchymal spinal cord hematoma formation with no known cause in human medicine. Multiple cases of spontaneous extraparenchymal spinal cord hematoma have not been described previously in veterinary medicine. To describe the signalment, clinical findings, magnetic resonance imaging (MRI) features, and surgical outcomes in histopathologically confirmed extraparenchymal spinal cord hematomas in dogs with no identified underlying etiology. Six dogs had MRI of the spinal cord, decompressive spinal surgery, and histopathologic confirmation of extraparenchymal spinal cord hematoma not associated with an underlying cause. Multi-institutional retrospective study. Six patients had spontaneous extraparenchymal spinal cord hematoma formation. MRI showed normal signal within the spinal cord parenchyma in all patients. All hematomas had T2-weighted hyperintensity and the majority (5/6) had no contrast enhancement. All dogs underwent surgical decompression and most patients (5/6) returned to normal or near normal neurologic function postoperatively. Follow-up of the patients (ranging between 921 and 1,446 days) showed no progression of neurologic clinical signs or any conditions associated with increased bleeding tendency. Before surgery and histopathology confirming extraparenchymal hematoma, the primary differential in most cases was neoplasia, based on the MRI findings. This retrospective study reminds clinicians of the importance of the combination of advanced imaging combined with histopathologic diagnosis. The prognosis for spontaneous spinal cord extraparenchymal hematoma with surgical decompression appears to be favorable in most cases.

    Purpose: A recent randomized clinical trial has demonstrated that direct decompressive surgery plus radiotherapy was superior to radiotherapy alone for the treatment of metastatic epidural spinal cord compression. The current study compared the cost-effectiveness of the two approaches. Methods and Materials: In the original clinical trial, clinical effectiveness was measured by ambulation and survival time until death. In this study, an incremental cost-effectiveness analysis was performed from a societal perspective. Costs related to treatment and posttreatment care were estimated and extended to the lifetime of the cohort. Weibull regression was applied to extrapolate outcomes in the presence of censored clinical effectiveness data. Results: From a societal perspective, the baseline incremental cost-effectiveness ratio (ICER) was found to be $60 per additional day of ambulation (all costs in 2003 Canadian dollars). Using probabilistic sensitivity analysis, 50% of all generated ICERs were lower than $57, and 95% were lower than $242 per additional day of ambulation. This analysis had a 95% CI of -$72.74 to 309.44, meaning that this intervention ranged from a financial savings of $72.74 to a cost of $309.44 per additional day of ambulation. Using survival as the measure of effectiveness resulted in an ICER of $30,940 per life-year gained. Conclusions: We found strong evidence that treatment of metastatic epidural spinal cord compression with surgery in addition to radiotherapy is cost-effective both in terms of cost per additional day of ambulation, and cost per life-year gained

    Paresthesias are relatively common during spinal needle insertion, however, the clinical significance of the paresthesia is unknown. A paresthesia may result from needle-to-nerve contact with a spinal nerve in the epidural space, or, with far lateral needle placement, may result from contact with a spinal nerve within the intervertebral foramen. However, it is also possible and perhaps more likely, that paresthesias occur when the spinal needle contacts a spinal nerve root within the subarachnoid space. This study was designed to test this latter hypothesis. Patients (n = 104) scheduled for surgery under spinal anesthesia were observed during spinal needle insertion. If a paresthesia occurred, the needle was fixed in place and the stylet removed to observe whether cerebrospinal fluid (CSF) flowed from the hub. The presence of CSF was considered proof that the needle had entered the subarachnoid space. Paresthesias occurred in 14/103 (13.6%) of patients; 1 patient experienced a paresthesia twice. All paresthesias were transient. Following a paresthesia, CSF was observed in the needle hub 86.7% (13/15) of the time. Our data suggest that the majority of transient paresthesias occur when the spinal needle enters the subarachnoid space and contacts a spinal nerve root. Therefore, when transient paresthesias occur during spinal needle placement it is appropriate to stop and assess for the presence of CSF in the needle hub, rather than withdraw and redirect the spinal needle away from the side of the paresthesia as some authors have suggested.

    The growing science and technology of various neurosurgical areas fosters subspecialization. The transmission of this expanding knowledge base to the neurosurgical resident becomes an increasing challenge. A survey of neurosurgical residency program directors was undertaken to evaluate their response to the budding subspecialization of spine surgery within general neurosurgery. A survey requesting background data, educational infrastructure and prevailing opinion was distributed to all 13 neurosurgical program directors in Canada. The responses were tabulated and results recorded. It is upon these results that conclusions and proposed directions are based. The current practice of the overwhelming majority of Canadian academic neurosurgical centers is to have neurosurgical spinal subspecialists working under the umbrella of the general neurosurgical division. A large percentage of neurosurgical program directors in Canada believe that the management of spinal disease, including both intradural procedures and instrumentation, is and should remain an integral part of general neurosurgical training. A consensus statement regarding the requirements of neurosurgical training in spinal disorders is the expressed desire of almost all program directors. A proposed direction and resolution is discussed.

    Full Text Available Pain intensity may be high in the postoperative period after spinal vertebral surgery. The aim of the study was to compare the effectiveness and cost of patient controlled analgesia (PCA with tramadol versus low dose tramadol-paracetamol on postoperative pain. A total of 60 patients were randomly divided into two groups. One group received 1.5 mg/kg tramadol (Group T while the other group received 0.75 mg/kg tramadol plus 1 g of paracetamol (Group P intravenously via a PCA device immediately after surgery and the patients were transferred to a recovery room, Tramadol was continuously infused at a rate of 0.5 mL/h in both groups, at a dose of 10 mg/mL in Group T and 5 mg/mL in Group P. The bolus and infusion programs were adjusted to administer a 1 mL bolus dose of tramadol with a lock time of 10 minutes. In Group P, 1 g of paracetamol was injected intravenously every 6 hours. The four-point nausea scale, numeric rating scale for pain assessment, Ramsey sedation scale, blood pressure, heart rate, respiration rate, peripheral oxygen saturation values and side effects were recorded at 0, 15 and 30 minutes, and at 1, 2, 4, 6, 12, 18 and 24 hours. The time to reach an Aldrete score of 9 was also recorded. A cost analysis for both groups was performed. In Group P, the numeric rating scale scores were significantly lower than that in Group T at 0 and 15 minutes. The number of side effects, additional analgesic requirement and the total dose of tramadol were lower in Group P than in Group T. However, the total cost of postoperative analgesics was significantly higher in Group P than in Group T (p < 0.001. We conclude that PCA using tramadol-paracetamol could be used safely for postoperative pain relief after spinal vertebral surgery, although at a higher cost than with tramadol alone.

    Full Text Available  Background: Calcium (Ca+2 plays an important role in many biophysiological mechanisms .The present study was carried out to assess alterations in total serum calcium level before and after operations in consider to the type of anesthesia. Materials and Methods: This descriptive study was conducted on 74 women who candidate for gynecological abdominal operations during one year at Al-zahra maternity Hospital in Rasht, Iran. The patients underwent General Anesthesia (GA (N=37 or Spinal Anesthesia (SA (N=37 randomly. Blood samples (2 cc, were obtained an hour before the anesthesia and two hours after that. The blood samples had been sent to the laboratory for analyzing .Total serum calcium level, magnesium (Mg and albumin level were measured by photometric methods. Inferential statistic was analyzed with the Vilkson non-parametric and Pearson's correlation test. P-values less than 0.05 have been considered as significant different. Results: There was a significant trend to decrease in calcium levels after all gynecological abdominal operations, but there was a significant correlation between General anesthesia (GA and reduction of serum calcium level (p=0.026 . Therefore, General Anesthesia (GA is accompanied by more calcium reduction than Spinal Anesthesia (SA. Conclusion: Serum Calcium levels tend to decrease after all gynecological abdominal surgeries, but General Anesthesia (GA is accompanied by more calcium reduction than Spinal one. It needs to further specific studies, to illustrate association between different methods of anesthesia and Ca+2 changes.

    Aim: To characterise the magnetic resonance imaging (MRI) appearance of patients with spinal accessory nerve (SAN) denervation. Material and methods: Twelve patients who had SAN denervation on electromyography (EMG) were included. The sternocleidomastoid and trapezius muscles and the SAN were assessed using MRI. Results: Trapezius muscle atrophy was seen in 11 (92%), and of those patients, T2/short tau inversion recovery (STIR) signal hyperintensity was also demonstrated in seven (58%). All three patients with prior neck surgery had scarring around the SAN, and one of these patients demonstrated a neuroma, which was confirmed surgically. Conclusion: Features of SAN neuropathy on MRI include atrophy and T2/STIR signal hyperintensity of the trapezius, and in patients who have had posterior triangle neck surgery, scarring may be seen around the nerve. - Highlights: • Spinal accessory nerve injury is most commonly the result of neck surgery. • MRI findings include trapezius muscle atrophy and T2 signal hyperintensity. • In cases of suspected injury, the course of the spinal accessory nerve should be assessed on MRI.

    The second half of the XXo century and especially the last 30 years have been the source of a great improvement for surgical treatment of spinal pathology essentially in 3 directions:--First, for the patient himself and his comfort by suppression for most of the cases of any post operative external support thanks to the rigidity, security and strength of segmental fixation given by the hooks, screws and rods systems, as well for posterior as anterior instrumentation. In addition, these new techniques allow the patient to return quickly to standing and walking activity and subsequently the surgery for adult people increased dramatically especially for all kind of degenerative diseases and more and more extended spinal deformities.--The second major improvement came from the real and new understanding of the 3 dimensions for all the physiology and pathology of the spine leading to practical applications for the design and surgical strategies for correction. The exploding expansion of the era of computer technology brought a lot of help in such understanding as well as for the development of spinal instrumentation.--Finally the impressive development of medical imaging with CT scan and less and less invasive techniques like MRI allow a much better vision of spinal cord and roots (a major concern for the spinal surgeon). All this occurs also because simultaneous revolution occurred in the field of anesthesia and intensive care especially post operatively, but also because the big progress for monitoring of vital function as well as neurological monitoring during surgery. The consequence of that was an improvement for the results concerning the patient for functional quality of life as well as for cosmesis. The subsequent failures resulting of these improvements came from various fields even if we exclude infection or neurological complications more and more controlled now.--At the level of the indications because of these lack of post operative external immobilization

    Bibliometric study of current literature. To catalog the most important minimally invasive spine (MIS) surgery articles using the amount of citations as a marker of relevance. MIS surgery is a relatively new tool used by spinal surgeons. There is a dynamic and evolving field of research related to MIS techniques, clinical outcomes, and basic science research. To date, there is no comprehensive review of the most cited articles related to MIS surgery. A systematic search was performed over three widely used literature databases: Web of Science, Scopus, and Google Scholar. There were four searches performed using the terms "minimally invasive spine surgery," "endoscopic spine surgery," "percutaneous spinal surgery," and "lateral interbody surgery." The amount of citations included was averaged amongst the three databases to rank each article. The query of the three databases was performed in November 2015. Fifty articles were selected based upon the amount of citations each averaged amongst the three databases. The most cited article was titled "Extreme Lateral Interbody Fusion (XLIF): a novel surgical technique for anterior lumbar interbody fusion" by Ozgur et al and was credited with 447, 239, and 279 citations in Google Scholar, Web of Science, and Scopus, respectively. Citations ranged from 27 to 239 for Web of Science, 60 to 279 for Scopus, and 104 to 462 for Google Scholar. There was a large variety of articles written spanning over 14 different topics with the majority dealing with clinical outcomes related to MIS surgery. The majority of the most cited articles were level III and level IV studies. This is likely due to the relatively recent nature of technological advances in the field. Furthermore level I and level II studies are required in MIS surgery in the years ahead. 5.

  16. Hemostatic function to regulate perioperative bleeding in patients undergoing spinal surgery: A prospective observational study.

    Atsushi Kimura

    Full Text Available Although bleeding is a common complication of surgery, routine laboratory tests have been demonstrated to have a low ability to predict perioperative bleeding. Better understanding of hemostatic function during surgery would lead to identification of high-risk patients for bleeding. Here, we aimed to elucidate hemostatic mechanisms to determine perioperative bleeding. We prospectively enrolled 104 patients undergoing cervical spinal surgery without bleeding diathesis. Blood sampling was performed just before the operation. Volumes of perioperative blood loss were compared with the results of detailed laboratory tests assessing primary hemostasis, secondary hemostasis, and fibrinolysis. Platelet aggregations induced by several agonists correlated with each other, and only two latent factors determined inter-individual difference. Platelet aggregability independently determined perioperative bleeding. We also identified low levels of plasminogen-activator inhibitor-1 (PAI-1 and α2-plasmin inhibitor to be independent risk factors for intraoperative and postoperative bleeding, respectively. Most important independent factor to determine postoperative bleeding was body weight. Of note, obese patients with low levels of PAI-1 became high-risk patients for bleeding during surgery. Our data suggest that bleeding after surgical procedure may be influenced by inter-individual differences of hemostatic function including platelet function and fibrinolysis, even in the patients without bleeding diathesis.

    Full Text Available We report a case of inadvertent hypothermia leading to severe hypotension resistant to high dose vasopressors, which responded to temperature correction in a patient undergoing spinal instrumentation surgery. A 60-year-old female developed severe hypotension during spinal instrumentation surgery. After review of all factors it was found to be secondary to hypothermia. The patient did not respond to high dose vasopressors. However, when normothermia was restored she recovered uneventfully. Patients undergoing lengthy spinal procedures in prone position are vulnerable to develop hypothermia and consequent cardiovascular depression so adequate measures should be taken to prevent hypothermia.

    To determine whether physiotherapy commenced within the first 4 weeks post-spinal surgery is safe and effective. Electronic databases CINAHL, MEDLINE, AMED, PubMed, Embase, and PEDro were searched from the earliest date possible through May 2015. An additional trial was identified through reference list scanning. Controlled trials evaluating comprehensive physiotherapy rehabilitation commenced within 4 weeks postoperatively compared with a control group receiving no physiotherapy, standard postoperative care, rest, less active physiotherapy, or sham physiotherapy after spinal surgery of a musculoskeletal etiology. Two reviewers independently applied inclusion and exclusion criteria, with disagreements discussed until consensus could be reached. Searching identified 3162 potentially relevant articles, of which 4 trials with 250 participants met the inclusion criteria. Data were extracted using a predefined data extraction form. Methodological quality of trials was assessed independently by 2 reviewers using the Downs and Black checklist. Pooled analyses were performed using a random-effects model with inverse variance methods to calculate risk differences and 95% confidence intervals (CIs) (dichotomous outcomes), and standardized mean differences (SMDs) and 95% CIs (continuous outcomes). When compared with no or sham physiotherapy, early comprehensive physiotherapy did not increase the risk of adverse events (risk difference, -.01; 95% CI, -.07 to .05; I(2)=0%). In addition, there is moderate-quality evidence demonstrating a reduction in pain by a moderate and significant amount at 12 weeks (SMD=-.38; 95% CI, -.66 to -.10; I(2)=0%) and at 12+ months (SMD=-.30; 95% CI, -.59 to -.02; I(2)=0%). Early comprehensive physiotherapy commenced within the first 4 weeks post-spinal surgery does not increase the potential for an adverse event and leads to a moderate, statistically significant reduction in pain when compared with a control group.

    Full Text Available ABSTRACT Purpose Postoperative urinary retention (POUR is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. Materials and Methods A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. Results There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%, 3 patients in Group II (5% and 4 patients in Group III (6.7% required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006. The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697. Conclusion This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

    Antifibrinolytics such as tranexamic acid reduce operative blood loss and blood product transfusion requirements in patients undergoing surgical correction of scoliosis. The factors involved in the unrelenting coagulopathy seen in scoliosis surgery are not well understood. One potential contributor is activation of the fibrinolytic system during a surgical procedure, likely related to clot dissolution and consumption of fibrinogen. The addition of tranexamic acid during a surgical procedure may mitigate the coagulopathy by impeding the derangement in D-dimer and fibrinogen kinetics. We retrospectively studied consecutive patients who had undergone surgical correction of adult spinal deformity between January 2010 and July 2016 at our institution. Intraoperative hemostatic data, surgical time, estimated blood loss, and transfusion records were analyzed for patients before and after the addition of tranexamic acid to our protocol. Each patient who received tranexamic acid and met inclusion criteria was cohort-matched with a patient who underwent a surgical procedure without tranexamic acid administration. There were 17 patients in the tranexamic acid cohort, with a mean age of 60.7 years, and 17 patients in the control cohort, with a mean age of 60.9 years. Estimated blood loss (932 ± 539 mL compared with 1,800 ± 1,029 mL; p = 0.005) and packed red blood-cell transfusions (1.5 ± 1.6 units compared with 4.0 ± 2.1 units; p = 0.001) were significantly lower in the tranexamic acid cohort. In all single-stage surgical procedures that met inclusion criteria, the rise of D-dimer was attenuated from 8.3 ± 5.0 μg/mL in the control cohort to 3.3 ± 3.2 μg/mL for the tranexamic acid cohort (p tranexamic acid cohort to 60.6 ± 35.1 mg/dL (p = 0.004). In patients undergoing spinal surgery, intravenous administration of tranexamic acid is effective at reducing intraoperative blood loss. Monitoring of D-dimer and fibrinogen during spinal surgery suggests that tranexamic acid

    During surgery for spinal deformities, accurate placement of pedicle screws may be guided by intraoperative cone-beam flat-detector CT. The purpose of this study was to identify appropriate paediatric imaging protocols aiming to reduce the radiation dose in line with the ALARA principle. Using O-arm registered (Medtronic, Inc.), three paediatric phantoms were employed to measure CTDI w doses with default and lowered exposure settings. Images from 126 scans were evaluated by two spinal surgeons and scores were compared (Kappa statistics). Effective doses were calculated. The recommended new low-dose 3-D spine protocols were then used in 15 children. The lowest acceptable exposure as judged by image quality for intraoperative use was 70 kVp/40 mAs, 70 kVp/80 mAs and 80 kVp/40 mAs for the 1-, 5- and 12-year-old-equivalent phantoms respectively (kappa = 0,70). Optimised dose settings reduced CTDI w doses 89-93%. The effective dose was 0.5 mSv (91-94,5% reduction). The optimised protocols were used clinically without problems. Radiation doses for intraoperative 3-D CT using a cone-beam flat-detector scanner could be reduced at least 89% compared to manufacturer settings and still be used to safely navigate pedicle screws.

    Virtual reality (VR)-based simulators offer numerous benefits and are very useful in assessing and training surgical skills. Virtual reality-based simulators are standard in some surgical subspecialties, but their actual use in spinal surgery remains unclear. Currently, only technical reviews of VR-based simulators are available for spinal surgery. Thus, we performed a systematic review that examined the existing research on VR-based simulators in spinal procedures. We also assessed the quality of current studies evaluating VR-based training in spinal surgery. Moreover, we wanted to provide a guide for future studies evaluating VR-based simulators in this field. This is a systematic review of the current scientific literature regarding VR-based simulation in spinal surgery. Five data sources were systematically searched to identify relevant peer-reviewed articles regarding virtual, mixed, or augmented reality-based simulators in spinal surgery. A qualitative data synthesis was performed with particular attention to evaluation approaches and outcomes. Additionally, all included studies were appraised for their quality using the Medical Education Research Study Quality Instrument (MERSQI) tool. The initial review identified 476 abstracts and 63 full texts were then assessed by two reviewers. Finally, 19 studies that examined simulators for the following procedures were selected: pedicle screw placement, vertebroplasty, posterior cervical laminectomy and foraminotomy, lumbar puncture, facet joint injection, and spinal needle insertion and placement. These studies had a low-to-medium methodological quality with a MERSQI mean score of 11.47 out of 18 (standard deviation=1.81). This review described the current state and applications of VR-based simulator training and assessment approaches in spinal procedures. Limitations, strengths, and future advancements of VR-based simulators for training and assessment in spinal surgery were explored. Higher-quality studies with

    Full Text Available Purpose. Transversus abdominis plane (TAP blocks have been shown to reduce pain and opioid requirements after abdominal surgery. The aim of the present case series was to demonstrate the use of TAP catheter injections of bupivacaine after major abdominal surgery. Methods. Fifteen patients scheduled for open colonic resection surgery were included. After induction of anesthesia, bilateral TAP catheters were placed, and all patients received a bolus dose of 20 mL bupivacaine 2.5 mg/mL with epinephrine 5 μg/mL through each catheter. Additional bolus doses were injected bilaterally 12, 24, and 36 hrs after the first injections. Supplemental pain treatment consisted of paracetamol, ibuprofen, and gabapentin. Intravenous morphine was used as rescue analgesic. Postoperative pain was rated on a numeric rating scale (NRS, 0–10 at regular predefined intervals after surgery, and consumption of intravenous morphine was recorded. Results. The TAP catheters were placed without any technical difficulties. NRS scores were ≤3 at rest and ≤5 during cough at 4, 8, 12, 18, 24, and 36 hrs after surgery. Cumulative consumption of intravenous morphine was 28 (23–48 mg (median, IQR within the first 48 postoperative hours. Conclusion. TAP catheter bolus injections can be used to prolong analgesia after major abdominal surgery.

    Despite widespread use of lumbar spinal fusion as a treatment for back pain, outcomes remain variable. Optimizing patient selection can help to reduce adverse outcomes. This literature review was conducted to better understand factors associated with optimal postoperative results after lumbar spinal fusion for chronic back pain and current tools used for evaluation. The PubMed database was searched for clinical trials related to psychosocial determinants of outcome after lumbar spinal fusion surgery; evaluation of commonly used patient subjective outcome measures; and perioperative cognitive, behavioral, and educational therapies. Reference lists of included studies were also searched by hand for additional studies meeting inclusion and exclusion criteria. Patients' perception of good health before surgery and low cardiovascular comorbidity predict improved postoperative physical functional capacity and greater patient satisfaction. Depression, tobacco use, and litigation predict poorer outcomes after lumbar fusion. Incorporation of cognitive-behavioral therapy perioperatively can address these psychosocial risk factors and improve outcomes. The 36-Item Short Form Health Survey, European Quality of Life five dimensions questionnaire, visual analog pain scale, brief pain inventory, and Oswestry Disability Index can provide specific feedback to track patient progress and are important to understand when evaluating the current literature. This review summarizes current information and explains commonly used assessment tools to guide clinicians in decision making when caring for patients with lower back pain. When determining a treatment algorithm, physicians must consider predictive psychosocial factors. Use of perioperative cognitive-behavioral therapy and patient education can improve outcomes after lumbar spinal fusion. Copyright © 2016 Elsevier Inc. All rights reserved.

    Previous studies show a limited alteration of gait at normal walking speed after spinal fusion surgery for adolescent idiopathic scoliosis (AIS), despite the presumed essential role of spinal mobility during gait. This study analyses how spinal fusion affects gait at more challenging walking speeds. More specifically, we investigated whether thoracic-pelvic rotations are reduced to a larger extent at higher gait speeds and whether compensatory mechanisms above and below the stiffened spine are present. 18 AIS patients underwent gait analysis at increasing walking speeds (0.45 to 2.22m/s) before and after spinal fusion. The range of motion (ROM) of the upper (thorax, thoracic-pelvic and pelvis) and lower body (hip, knee and ankle) was determined in all three planes. Spatiotemporal parameters of interest were stride length and cadence. Spinal fusion diminished transverse plane thoracic-pelvic ROM and this difference was more explicit at higher walking speeds. Transversal pelvis ROM was also decreased but this effect was not affected by speed. Lower body ROM, step length and cadence remained unaffected. Despite the reduction of upper body ROM after spine surgery during high speed gait, no altered spatiotemporal parameters or increased compensatory ROM above or below the fusion (i.e. in the shoulder girdle or lower extremities) was identified. Thus, it remains unclear how patients can cope so well with such major surgery. Future studies should focus on analyzing the kinematics of individual spinal levels above and below the fusion during gait to investigate possible compensatory mechanisms within the spine.

    Objective: To evaluate the diagnostic and clinical value of fast contrast-enhanced MR angiography (CE-MRA) with elliptic centric phase-encoding in spinal cord vascular malformations. Methods Fast three-dimensional contrast-enhanced MR angiography with elliptic centric phase-encoding and superconducting 1.5T system was applied prospectively in twenty-five consecutive patients with clinically suspected of spinal cord vascular malformations. All cases were performed with selective spinal digital subtraction angiography, including 18 cases treated by surgery and 2 of them with embolization before surgery, MR angiography follow up were undertaken in ten patients after surgery. Comparing fast contrast-enhanced MR angiography with DSA in diagnosing spinal cord vascular malformations included the origin of feeding artery, the feeding artery, the fistula or the nidus, the draining vein, and the vessel image quality based on the gold standard of selective spinal digital subtraction angiography. Results: Surgically proven diseases included spinal arteriovenous malformations(3 cases), spinal cord perimedullary arteriovenous fistulas (5 cases), spinal dural arteriovenous fistulas (8 cases), paravertebral arteriovenous fistulas (1 case), and spontaneous spinal epidural hematomas (2 eases). Comparing with DSA, the accuracy of MR angiography in diagnosing spinal cord vascular malformations; and detecting the origin of the feeding artery, the feeding artery, the shunt or the nidus and the draining vein were 93.8%, 92%, 96.2%, 100% and 100%, respectively. Overall the degree vascular enhencement were judged to be similar(P>0.05), but the vessel continuity of MRA was inferior to DSA (P<0.05). However, 9 cases of MRA showed no abnormal vascular malformation coinciding with those of surgery. Posttreatment MR angiography did not depict any abnormal vessels again. Conclusions: Fast three-dimensional contrast-enhanced MR angiography with elliptic centric phase-encoding may provide

    Full Text Available BACKGROUND: The NF-κB pathway and chemokine (C-C motif ligand 5 (CCL5 are involved in pain modulation; however, the precise mechanisms of their interactions in chronic neuropathic pain have yet to be established. METHODS: The present study examined the roles of spinal NF-κB and CCL5 in a neuropathic pain model after chronic constriction injury (CCI surgery. CCI-induced pain facilitation was evaluated using the Plantar and von Frey tests. The changes in NF-κB and CCL5 expression were analyzed by immunohistochemistry and Western blot analyses. RESULTS: Spinal NF-κB and CCL5 expression increased after CCI surgery. Repeated intrathecal infusions of pyrrolidine dithiocarbamate (PDTC, a NF-κB inhibitor decreased CCL5 expression, inhibited the activation of microglia and astrocytes, and attenuated CCI-induced allodynia and hyperalgesia. Intrathecal injection of a CCL5-neutralizing antibody attenuated CCI-induced pain facilitation and also suppressed spinal glial cell activation after CCI surgery. However, the CCL5-neutralizing antibody did not affect NF-κB expression. Furthermore, selective glial inhibitors, minocycline and fluorocitrate, attenuated the hyperalgesia induced by intrathecal CCL5. CONCLUSIONS: The inhibition of spinal CCL5 expression may provide a new method to prevent and treat nerve injury-induced neuropathic pain.

    Full Text Available Abstract Introduction Isolated long thoracic nerve injury causes paralysis of the serratus anterior muscle. Patients with serratus anterior palsy may present with periscapular pain, weakness, limitation of shoulder elevation and scapular winging. Case presentation We present the case of a 23-year-old woman who sustained isolated long thoracic nerve palsy during anterior spinal surgery which caused external compressive force on the nerve. Conclusion During positioning of patients into the lateral decubitus position, the course of the long thoracic nerve must be attended to carefully and the nerve should be protected from any external pressure.

    Lumbar spinal stenosis (LSS) is the most common lumbar degenerative disease, and sagittal imbalance is uncommon. Forward-bending posture, which is primarily caused by buckling of the ligamentum flavum, may be improved via simple decompression surgery. The objectives of this study were to identify the risk factors for sagittal imbalance and to describe the outcomes of simple decompression surgery. This is a retrospective nested case-control study PATIENT SAMPLE: This was a retrospective study that included 83 consecutive patients (M:F=46:37; mean age, 68.5±7.7 years) who underwent decompression surgery and a minimum of 12 months of follow-up. The primary end point was normalization of sagittal imbalance after decompression surgery. Sagittal imbalance was defined as a C7 sagittal vertical axis (SVA) ≥40 mm on a 36-inch-long lateral whole spine radiograph. Logistic regression analysis was used to identify the risk factors for sagittal imbalance. Bilateral decompression was performed via a unilateral approach with a tubular retractor. The SVA was measured on serial radiographs performed 1, 3, 6, and 12 months postoperatively. The prognostic factors for sagittal balance recovery were determined based on various clinical and radiological parameters. Sagittal imbalance was observed in 54% (45/83) of patients, and its risk factors were old age and a large mismatch between pelvic incidence and lumbar lordosis. The 1-year normalization rate was 73% after decompression surgery, and the median time to normalization was 1 to 3 months. Patients who did not experience SVA normalization exhibited low thoracic kyphosis (hazard ratio [HR], 1.04; 95% confidence interval [CI], 1.02-1.10) (pimbalance was observed in more than 50% of LSS patients, but this imbalance was correctable via simple decompression surgery in 70% of patients.

    2012-09-01

    Developments in oncological and medical therapies mean that life expectancy of patients with metastatic bone disease (MBD) is often measured in years. Complications of MBD may dramatically and irreversibly affect patient quality of life, making the careful assessment and appropriate management of these patients essential. The roles of orthopaedic and spinal surgeons in MBD generally fall into one of four categories: diagnostic, the prophylactic fixation of metastatic deposits at risk of impending fracture (preventative surgery), the stabilisation or reconstruction of bones affected by pathological fractures (reactive surgery), or the decompression and stabilisation of the vertebral column, spinal cord, and nerve roots. Several key principals should be adhered to whenever operating on skeletal metastases. Discussions should be held early with an appropriate multi-disciplinary team prior to intervention. Detailed pre-assessment is essential to gauge a patient's suitability for surgery - recovery from elective surgery must be shorter than the anticipated survival. Staging and biopsies provide prognostic information. Primary bone tumours must be ruled out in the case of a solitary bone lesion to avoid inappropriate intervention. Prophylactic surgical fixation of a lesion prior to a pathological fracture reduces morbidity and length of hospital stay. Regardless of a lesion or pathological fracture's location, all regions of the affected bone must be addressed, to reduce the risk of subsequent fracture. Surgical implants should allow full weight bearing or return to function immediately. Post-operative radiotherapy should be utilised in all cases to minimise disease progression. Spinal surgery should be considered for those with spinal pain due to potentially reversible spinal instability or neurological compromise. The opinion of a spinal surgeon should be sought early, as delays in referral directly correlate to worse functional recovery following intervention

    Non-traumatic extradural spinal haematoma is an uncommon condition that is usually associated with a poor outcome. It may present acutely with signs and symptoms of major neurological dysfunction secondary to cord compression, or subacutely over a number of days or weeks with fluctuating symptoms. The exact aetiology of this condition is incompletely understood, but it is believed that the blood is venous in origin, as distinct from the arterial origin of intracranial extradural haematomas. Causes of non-traumatic extradural spinal haematoma include anticoagulation, vasculitis such as systemic lupus erythematosus (SLE), and spinal arteriovenous malformations. Conditions that may mimic an acute spinal haematoma include extradural abscess and extradural metastatic infiltration. It is important to make a diagnosis of extradural compression because surgery may offer the best hope in restoring neurological function in these patients. Imaging modalities used for the investigation of extradural haematomas include myelography, CT myelography (CTM) and MRI with or without gadolinium enhancement. The MR appearances of acute extradural abscess and extradural tumour can mimic an extradural haematoma. In subacute haematoma, owing to the magnetic properties of blood degradation products, MR is more specific in diagnosing and ageing of the haematoma.

    SAMUEL MACHADO MARTINS

    Full Text Available ABSTRACT Objective: To investigate the relationship between preoperative vitamin D and albumin levels and postoperative quality of life in patients undergoing spinal surgery. Methods: Patients undergoing thoracic and lumbar spine surgery were evaluated in this prospective study. Their vitamin D and albumin levels were assessed before surgery and quality of life was measured by two questionnaires, Oswestry Disability Index (ODI and Scoliosis Research Society - 22 (SRS-22, one year after the procedure. Data on infection occurrence and healing time were collected. Preoperative nutritional values and patients’ quality of life were analyzed using the chi-square test and ANOVA for albumin and vitamin D, respectively. The relationship among nutritional status, healing time, and the occurrence of infection was evaluated by the Pearson correlation coefficient. Results: Forty-six patients were included and their mean nutritional values were 19.1 (6.6 ng/mL for vitamin D and 3.9 (0.6 g/dL for albumin [mean (standard deviation]. No association was found between vitamin D and quality of life of patients measured by ODI (p=0.534 and SRS-22 (p=0.739 questionnaires. There was also no association between albumin levels and quality of life measured by ODI (p=0.259 and SRS-22 (p=0.076 questionnaires. No correlation was found between the healing time or occurrence of infection and nutritional values. Conclusions: There was no association between vitamin D and albumin levels and the surgical result, according to the patient’s perception, besides the occurrence of complications with the surgical wound.

    Guillain-Barre Syndrome (GBS) is the most common disease resulting in acute diffuse flaccid paralysis. It is an autoimmune disease that can occur at any age. The clinical course is characterized by weakness in the arms and legs, areflexia and the progression of muscle weakness from the lower limbs to the upper limbs. The most common causes of GBS include infections, vaccinations, surgery and some medicines. We present the case of a 48 years old male patient, who developed GBS after undergoing surgery for renal calculus, under spinal anaesthesia. In this case report, we presented a rather rare case of GBS occurring following spinal anaesthesia. (author)

    Full Text Available Quadriplegia following spinal anaesthesia due to spinal epidural haematoma is a rare but critical complication that usually occurs within 24 hours to a few days of the procedure. I report a case of a 32 year old male who underwent Uretero - Renal Scopy (URS and double ‘J’ (DJ stenting for right ureteric calculus under spinal anaesthesia. The patient was on nonsteroidal anti - inflammatory agents (NSAIDS and oral Prednisolone for sero - negative rheumatoid arthritis. The preoperative investigations were normal. About four hours after surgery, the patient developed paraesthesia of lower limbs, a little later paraplegia and gradually quadriplegia within 12 to 15 hours of surgery. Magnetic Resonance Imaging (MRI revealed an extensive spinal epidural haematoma and cord oedema extending from C2 to L5 vertebrae. In consultation with neuro - surgeon, the patient was treated conservatively, while awaiting for the results of coagulation profile, which proved to be Haemophilia. By the end of 2nd and 3rd postoperative day, the upper limbs showed signs of recovery and within a week’s time, both the upper limbs regained normal power and tone. The lower limbs showed sensory as well as motor recovery by 3 rd week and about total recovery to normalcy by 6 weeks. Residual paresis remained in left lower limb. The patient was sent for physiotherapy and he recovered completely by 9 months

    Full Text Available Background and Aims: The study was undertaken to evaluate postoperative benefit in patients administered tablet gabapentin as premedication with the primary outcome determining the effect on duration of analgesia with total analgesic requirement and measurement of postoperative sedation scores as our secondary outcomes. Methods: The study was a prospective randomized observational study in sixty patients undergoing surgeries in spinal anesthesia (SA. Patients were randomly assigned into two groups. Group A (n = 30 patients received tablet gabapentin (600 mg while Group B (n = 30 received a placebo (Vitamin B complex orally 2 h before surgery. Postoperative pain was managed with intravenous tramadol 2 mg/kg. Postoperative monitoring and assessment included pain assessment every 2 h with Numeric Rating Scale (0–10 for 12 h and then at 24 h. Results: On comparison of intergroup data, the duration of analgesia was prolonged in Group A (288.79 ± 38.81 min as compared to Group B (218.67 ± 37.62 min with P (0.0001. Total opioid requirement was higher in placebo group as compared to the Group A (P = 0.025. Statistical difference in mean (standard deviation pain score at 24 h was statistically significant (P = 0.0002. Sedation scores were significantly higher in Group A at 2 and 4 h post-SA. Conclusion: Single dose of gabapentin administered 2 h before surgery provides better pain control as compared to placebo. It prolongs the duration of analgesia, reduces the total analgesic requirement during the postoperative period.

  19. Plasma fibronectin in patients undergoing major surgery

    Plasma fibronectin in patients undergoing major surgery had been determined before and after operation. The study was done on 15 patients and 15 normal healthy individuals. The study revealed that patients subjected to major operation, their fibronectin level was normal before operation followed by reduction one day post-operation. After one week, fibronectin level raised again nearly to the pre-operations levels. The probable mechanisms of fibronectin in healing processes were discussed. Fibronectin (FN) is a family of structurally and immunologically related high molecular weight glycoproteins that are present in many cell surfaces, in extracellular fluids, in connective tissues and in most membranes. Interaction with certain discrete extracellular substances, such as a glucosaminoglycans (e.g. heparin), fibrin and collagen and with cell surface structure seem to account for many of its biological activities, among which are regulation of adhesion, spreading and locomotion (Mosesson and amrani, 1980). The concentration of Fn in human plasma decreases after extensive destruction such as that occurs in major surgery, burns or other trauma. This decrease has been generally though to be due to increased consumption of soluble plasma Fn in opsonization of particulate and soluble debris from circulation by the reticuloendothelial (RE) system. Fn rapidly appears in injury areas, in experimentally induced blisters, wounded and epithelium tissues (Petersen et al., 1985). Fn accumulates at times of increased vascular permeability and it is produced by cell of blood vessels in response to injury

  20. Radionuclide imaging of spinal infections

    The diagnosis of spinal infection, with or without implants, has been a challenge for physicians for many years. Spinal infections are now being recognised more frequently, owing to aging of the population and the increasing use of spinal-fusion surgery. The diagnosis in many cases is delayed, and this may result in permanent neurological damage or even death. Laboratory evidence of infection is variable. Conventional radiography and radionuclide bone imaging lack both sensitivity and specificity. Neither in vitro labelled leucocyte scintigraphy nor 99m Tc-anti-granulocyte antibody scintigraphy is especially useful, because of the frequency with which spinal infection presents as a non-specific photopenic area on these tests. Sequential bone/gallium imaging and 67 Ga-SPECT are currently the radionuclide procedures of choice for spinal osteomyelitis, but these tests lack specificity, suffer from poor spatial resolution and require several days to complete. [ 18 F]Fluoro-2-deoxy-D-glucose (FDG) PET is a promising technique for diagnosing spinal infection, and has several potential advantages over conventional radionuclide tests. The study is sensitive and is completed in a single session, and image quality is superior to that obtained with single-photon emitting tracers. The specificity of FDG-PET may also be superior to that of conventional tracers because degenerative bone disease and fractures usually do not produce intense FDG uptake; moreover, spinal implants do not affect FDG imaging. However, FDG-PET images have to be read with caution in patients with instrumented spinal-fusion surgery since non-specific accumulation of FDG around the fusion material is not uncommon. In the future, PET-CT will likely provide more precise localisation of abnormalities. FDG-PET may prove to be useful for monitoring response to treatment in patients with spinal osteomyelitis. Other tracers for diagnosing spinal osteomyelitis are also under investigation, including radiolabelled

    Spinal tumors are uncommon lesions but may cause significant morbidity in terms of limb dysfunction. In establishing the differential diagnosis for a spinal lesion, location is the most important feature, but the clinical presentation and the patient's age and gender are also important. Magnetic resonance (MR) imaging plays a central role in the imaging of spinal tumors, easily allowing tumors to be classified as extradural, intradural-extramedullary or intramedullary, which is very useful in tumor characterization. In the evaluation of lesions of the osseous spine both computed tomography (CT) and MR are important. We describe the most common spinal tumors in detail. In general, extradural lesions are the most common with metastasis being the most frequent. Intradural tumors are rare, and the majority is extramedullary, with meningiomas and nerve sheath tumors being the most frequent. Intramedullary tumors are uncommon spinal tumors. Astrocytomas and ependymomas comprise the majority of the intramedullary tumors. The most important tumors are documented with appropriate high quality CT or MR images and the characteristics of these tumors are also summarized in a comprehensive table. Finally we illustrate the use of the new World Health Organization (WHO) classification of neoplasms affecting the central nervous system

    OBJECTIVE The subspecialization of neurosurgical practice is an ongoing trend in modern neurosurgery. However, it remains unclear whether the degree of surgeon specialization is associated with improved patient outcomes. The authors hypothesized that a trend toward increased neurosurgeon specialization was associated with improved patient morbidity and mortality rates. METHODS The Nationwide Inpatient Sample (NIS) was used (1998-2009). Patients were included in a spinal analysis cohort for instrumented spine surgery involving the cervical spine ( International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 81.31-81.33, 81.01-81.03, 84.61-84.62, and 84.66) or lumbar spine (codes 81.04-81.08, 81.34-81.38, 84.64-84.65, and 84.68). A cranial analysis cohort consisted of patients receiving a parenchymal excision or lobectomy operation (codes 01.53 and 01.59). Surgeon specialization was measured using unique surgeon identifiers in the NIS and defined as the proportion of a surgeon's total practice dedicated to cranial or spinal cases. RESULTS A total of 46,029 and 231,875 patients were identified in the cranial and spinal analysis cohorts, respectively. On multivariate analysis in the cranial analysis cohort (after controlling for overall surgeon volume, patient demographic data/comorbidities, hospital characteristics, and admitting source), each percentage-point increase in a surgeon's cranial specialization (that is, the proportion of cranial cases) was associated with a 0.0060 reduction in the log odds of patient mortality (95% CI 0.0034-0.0086) and a 0.0042 reduction in the log odds of morbidity (95% CI 0.0032-0.0052). This resulted in a 15% difference in the predicted probability of mortality for neurosurgeons at the 75th versus the 25th percentile of cranial specialization. In the spinal analysis cohort, each percentage-point increase in a surgeon's spinal specialization was associated with a 0.0122 reduction in the log odds of

    Penetrating spinal injury (PSI), although an infrequent injury in the civilian population, is not an infrequent injury in military conflicts. Throughout military history, the role of surgery in the treatment of PSI has been controversial. The US is currently involved in 2 military campaigns, the hallmark of both being the widespread use of various explosive devices. The authors reviewed the evidence for or against the use of decompressive laminectomy to treat PSI to provide a triservice (US Army, Navy, and Air Force) consensus and treatment recommendations for military neurosurgeons and spine surgeons. A US National Library of Medicine PubMed database search that identified all literature dealing with acute management of PSI from military conflicts and civilian urban trauma centers in the post-Vietnam War period was undertaken. Nineteen retrospective case series (11 military and 8 civilian) met the study criteria. Eleven military articles covered a 20-year time span that included 782 patients who suffered either gunshot or blast-related projectile wounds. Four papers included sufficient data that analyzed the effectiveness of surgery compared with nonoperative management, 6 papers concluded that surgery was of no benefit, 2 papers indicated that surgery did have a role, and 3 papers made no comment. Eight civilian articles covered a 9-year time span that included 653 patients with spinal gunshot wounds. Two articles lacked any comparative data because of treatment bias. Two papers concluded that decompressive laminectomy had a beneficial role, 1 paper favored the removal of intracanal bullets between T-12 and L-4, and 5 papers indicated that surgery was of no benefit. Based on the authors' military and civilian PubMed literature search, most of the evidence suggests that decompressive laminectomy does not improve neurological function in patients with PSI. However, there are serious methodological shortcomings in both literature groups. For this and other reasons

    Medical records of 13 dogs with spinal meningiomas were reviewed. Breed predilections were not found. Males outnumbered females 9 to 4, and most of the dogs were middle-aged. All dogs had motor deficits of various degrees, and approximately half of the dogs had clinical signs of mild to moderate spinal pain. The remainder had histories of clinical signs suggestive of chronic discomfort. There was a prolonged (greater than 3 months) delay between the onset of signs and diagnosis, except in 3 dogs. The neurologic courses usually were progressive. Results of noncontrast spinal radiography were normal in 10 dogs; in 3 dogs, the lamina appeared scalloped. Results of myelography contributed to the correct diagnosis in 10 of 12 dogs; however, in 2 dogs, intradural/extramedullary tumors were thought to be intramedullary lesions. A preponderance of cervical meningiomas was found, accounting for 10 of 13 tumors. Lumbar meningiomas were found in the remaining 3 dogs. Surgery was performed in 9 of the dogs, six of which improved after surgery. Poor results were correlated with tumors that involved spinal cord segments of an intumescence, ventrally located tumors, iatrogenic trauma, and tumor invasion into adjacent neural parenchyma. Four of 13 spinal meningiomas were found to be invasive into the spinal cord itself

    Full Text Available This mini review describes the current surgical strategy for restoring function after traumatic spinal nerve root avulsion in brachial or lumbosacral plexus injury in man. As this lesion is a spinal cord or central nervous injury functional return depends on spinal cord nerve cell growth within the central nervous system. Basic science, clinical research and human application has demonstrated good and useful motor function after ventral root avulsion followed by spinal cord reimplantation. Recently, sensory return could be demonstrated following spinal cord surgery bypassing the injured primary sensory neuron. Experimental data showed that most of the recovery depended on new growth reinnervating peripheral receptors. Restored sensory function and the return of spinal reflex was demonstrated by electrophysiology and functional magnetic resonance imaging of human cortex. This spinal cord surgery is a unique treatment of central nervous system injury resulting in useful functional return. Further improvements will not depend on surgical improvements. Adjuvant therapy aiming at ameliorating the activity in retinoic acid elements in dorsal root ganglion neurons could be a new therapeutic avenue in restoring spinal cord circuits after nerve root avulsion injury.

    Disability is not a category of disease but rather relates to the physical, sensory, cognitive, and/or mental disorders that substantially limit one or more major life activities. These functional limitations have been found to be predictive of suicide, with psychiatric comorbidities increasing the risk for suicide. Enormous gaps exist in the understanding of the relationship between disability and suicide. We reviewed the current literature addressing the prevalence of and risk factors for suicide among persons with three major disabling conditions and identify priorities for future research. We performed a literature review investigating the relationship between three major disabilities (intellectual disability, spinal cord injury, multiple sclerosis) and suicide. To ensure thorough evaluation of the available literature, we searched PubMed, the Cochrane Library, and Google Scholar with terms including "suicide," "disability," "intellectual disability," "spinal cord injury," "multiple sclerosis," and permutations thereof. By this method we evaluated 110 articles and included 21 in the review. Suicide rates are significantly higher among persons with multiple sclerosis and spinal cord injury than in the general population. A more nuanced picture of suicide rates and risk factors exists for the intellectual disability population, in which it appears that rates of suicide risk factors are higher than among the general population while suicide rates may be lower. The highest rates of suicide are reported among study populations of persons with multiple sclerosis, followed by persons with spinal cord injury, and then individuals with intellectual disability. Suicide among persons with disabilities is a complex and pressing public health concern. Urgent research priorities include (1) valid estimates of suicide rates among persons with disabilities by age cohort; (2) assessment of the predictive importance of suicide risk factors; and (3) determination of best

    Full Text Available Background: Spinal anaesthesia is the preferred technique to fix fracture of the femur. Extreme pain does not allow ideal positioning for this procedure. Intravenous fentanyl and femoral nerve block are commonly used techniques to reduce the pain during position for spinal anaesthesia however; results are conflicting regarding superiority of femoral nerve block over intravenous fentanyl. Aims: We conducted this study to compare the analgesic effect provided by femoral nerve block (FNB and intra- venous (IV fentanyl prior to positioning for central neuraxial block in patients undergoing surgery for femur fracture. Patients and Methods: In this randomized prospective study 60 patients scheduled for fracture femur operation under spinal were included. Patients were distributed in two groups through computer generated random numbers table; Femoral nerve block group (FNB and Intravenous fentanyl group (FENT. In FNB group patients received FNB guided by a peripheral nerve stimulator (Stimuplex; B Braun, Melsungen, AG 5 minutes prior to positioning. 20mL, 1.5% lidocaine with adrenaline (1:200,000 was injected incrementally after a negative aspiration test. Patients in the fentanyl group received injection fentanyl 1 μg/kg IV 5 mins prior to positioning. Spinal block was performed and pain scores before and during positioning were recorded. Statistical analysis was done with Sigmaplot version-10 computer software. Student t-test was applied to compare the means and P < 0.05 was taken as significant. Results: VAS during positioning in group FNB: 0.57 ± 0.31 versus FENT 2.53 ± 1.61 (P = 0.0020. Time to perform spinal anesthesia in group FNB: 15.33 ± 1.64 min versus FENT 19.56 ± 3.09 min (P = 0.000049. Quality of patient positioning for spinal anesthesia in group FNB 2.67± 0.606 versus FENT 1.967 ± 0.85 (P = 0.000027. Patient acceptance was less in group FENT (P = 0.000031.

    Spinal anaesthesia (SA) and general anaesthesia (GA) are widely used techniques for vaginal surgery for pelvic floor disorders with inconclusive evidence of the superiority of either. We conducted a randomised controlled trial (RCT) to assess the feasibility of a full scale RCT aiming to examine the effect of anaesthetic mode for vaginal surgery on operative, patient reported and length of hospital stay (LOHS) outcomes. Patients undergoing vaginal surgery, recruited through a urogynaecology service in a University teaching hospital, were randomised to receive either GA or SA. Patients were followed up for 12 weeks postoperatively. Pain was measured on a visual analogue scale; nausea was assessed with a four-point verbal rating scale. Patient's subjective perception of treatment outcome, quality of life (QoL) and functional outcomes were assessed using the International Consultation on Incontinence Modular Questionnaire (ICIQ) on vaginal symptoms and the SF-36 questionnaire. Sixty women were randomised, 29 to GA and 31 to SA. The groups were similar in terms of age and type of vaginal surgery performed. No statistically significant differences were noted between the groups with regard to pain, nausea, quality of life (QoL), functional outcomes as well as length of stay in the postoperative recovery room, use of analgesia postoperatively and LOHS. This study has demonstrated that a full RCT is feasible and should focus on the length of hospital stay in a subgroup of patients undergoing vaginal surgery where SA may help to facilitate enhanced recovery or day surgery.

  14. Oriental Medical Treatment of Lumbar Spinal Stenosis

    Full Text Available Lumbar spinal stenosis results from the progressive combined narrowing of the central spinal canal, the neurorecesses, and the neuroforaminal canals. In the absence of prior surgery, tumor, or infection, the spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposis posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins, or a combination of two or more of the above factors. Patients with spinal stenosis become symptomatic when pain, motor weakness, paresthesia, or other neurologic compromise causes distress. In one case, we administrated oriental medical treatment with acupuncture treatment and herb-medicine. Oriental medical treatment showed desirable effect on lumbar spinal stenosis.

    During spine surgery, the spinal cord is electrophysiologically monitored via transcranial electrical stimulation of motor-evoked potentials (TES-MEPs) to prevent injury. Transcranial electrical stimulation of motor-evoked potential involves the use of either constant-current or constant-voltage stimulation; however, there are few comparative data available regarding their ability to adequately elicit compound motor action potentials. We hypothesized that the success rates of TES-MEP recordings would be similar between constant-current and constant-voltage stimulations in patients undergoing spine surgery. The objective of this study was to compare the success rates of TES-MEP recordings between constant-current and constant-voltage stimulation. This is a prospective, within-subject study. Data from 100 patients undergoing spinal surgery at the cervical, thoracic, or lumbar level were analyzed. The success rates of the TES-MEP recordings from each muscle were examined. Transcranial electrical stimulation with constant-current and constant-voltage stimulations at the C3 and C4 electrode positions (international "10-20" system) was applied to each patient. Compound muscle action potentials were bilaterally recorded from the abductor pollicis brevis (APB), deltoid (Del), abductor hallucis (AH), tibialis anterior (TA), gastrocnemius (GC), and quadriceps (Quad) muscles. The success rates of the TES-MEP recordings from the right Del, right APB, bilateral Quad, right TA, right GC, and bilateral AH muscles were significantly higher using constant-voltage stimulation than those using constant-current stimulation. The overall success rates with constant-voltage and constant-current stimulations were 86.3% and 68.8%, respectively (risk ratio 1.25 [95% confidence interval: 1.20-1.31]). The success rates of TES-MEP recordings were higher using constant-voltage stimulation compared with constant-current stimulation in patients undergoing spinal surgery. Copyright © 2017

    We hypothesized that cooling hyperbaric bupivacaine from 23 to 5 °C may limit the intrathecal spread of bupivacaine and therefore increase the success rate of unilateral spinal anesthesia and decrease the rate of hemodynamic complications. A hundred patients scheduled for elective unilateral inguinal hernia surgery were randomly allocated to receive 1.8 ml of 0.5 % hyperbaric bupivacaine intrathecally at either 5 °C (group I, n = 50) or at 23 °C (group II, n = 50). Following spinal block at the L2-3 interspace, the lateral decubitus position was maintained for 15 min. Unilateral spinal anesthesia was assessed and confirmed at 15 and 30 min. The levels of sensory and motor block on the operative side were evaluated until complete resolution. The rate of unilateral spinal anesthesia at 15 and 30 min was significantly higher in group I (p = 0.015 and 0.028, respectively). Hypotensive events and bradycardia were significantly rarer in group I (p = 0.014 and 0.037, respectively). The density and viscosity of the solution at 5 °C was significantly higher than at 23 °C (p < 0.0001). Compared with group II, sensory block peaked later in group I (17.4 vs 12.6 min) and at a lower level (T9 vs T7), and two-segment regression of sensory block (76.4 vs 84.3 min) and motor block recovery was shorter (157.6 vs 193.4 min) (p < 0.0001). Cooling of hyperbaric bupivacaine to 5 °C increased the density and viscosity of the solution and the success rate of unilateral spinal anesthesia, and decreased the hemodynamic complication rate.

    Low back pain is a global problem affecting one in 10 people. The management of low back pain varies from conservative to more invasive methods with a spectacular increase in the number of patients undergoing spinal fusion surgery during the last decade. Conventional radiological and radionuclide studies are often used in the assessment of persistent or recurring pain after spinal surgery with several advantages and limitations related to each technique. This article reviews the key contribution of integrated bone SPECT/CT in evaluating patients with persistent or recurring pain after spinal surgery, focusing on spinal fusion. Current literature supports the use of bone SPECT/CT as an adjunct imaging modality and problem-solving tool in evaluating patients with suspicion of pseudarthrosis, adjacent segment degeneration, and hardware failure. The role of bone SPECT/CT in post-operative orthopaedic scenarios is evolving, and this review highlights the need for further research on the role of bone SPECT/CT in these patients. (orig.)

    The aim of the study was to evaluate the presence of urinary incontinence in patients with chronic degenerative spinal disease and to identify factors affecting the occurrence and changes in urinary incontinence after surgery. The group evaluated comprised 214 patients undergoing surgery for degenerative spinal disease at our department between January 1 and December 31, 2008. The patients were categorised according to the type of their degenerative disease (cervical disc herniation, lumbar disc herniation, spinal stenosis, spinal instability or olisthesis) and the spine level involved (cervical or lumbar spine). The symptoms of urinary incontinence included leakage of urine and non-obstructive chronic urinary retention developing in association with the manifestation of vertebrogenic disorder. Patients with diseases known to increase the risk of incontinence were not included in the study. Based on a retrospective analysis of the patients' clinical notes, the occurrence of urinary incontinence in each type of degenerative spinal disease was assessed. The effect of gender, age, body mass index (BMI), neurological status and spinal disease type on the development of incontinence was statistically evaluated. The efficacy of surgical treatment was assessed on the basis of the patients' subjective complaints at the first follow-up one month after surgery. The data were evaluated by the statistical programme InSTAT (analysis of variance ANOVA, t-test). All tests were two-sided; a 0.05 level of statistical significance was used. Of the 214 patients with degenerative spinal disease, 27 (12.6%) had urinary incontinence. A higher risk of developing incontinence was found in women (p = 0.008) and in patients with radicular weakness (p = 0.023). The patients with urinary incontinence had their BMI significantly lower than patients without this disorder (p = 0.019). Age had no effect. The differences in the occurrence of urinary incontinence amongst the different types of

    We examined the effectiveness of tranexamic acid in preventing intraoperative blood loss during major cardiac surgery. Out of initial 81 patients undergoing major cardiac surgery (both coronary artery bypass and valve repair procedures) at our teaching hospital, sixty-seven patients were selected for this study. We compared estimated blood loss, decrease in percent hemoglobin and hematocrit following surgery between two groups of patients (none of them received any blood product during surgery), one group receiving no tranexamic acid (n=17) and another group receiving tranexamic acid (n=25). In the second study, we combined these patients with patients receiving modest amounts of blood products (1-2 unit) and compared these parameters between two groups of patients (25 patients received no tranexamic acid, 42 patients received tranexamic acid). In patients who received no blood product during surgery, those who received no tranexamic acid showed statistically significant (independent t-test two tailed at p tranexamic acid (mean: 987.2 mL, SD: 459.9, n=25). We observed similar results when the patients receiving no blood products and patients receiving modest amount of blood products were combined based on the use of tranexamic acid or not. No statistically significant difference was observed in percent reduced hemoglobin or hematocrit following surgery in any group of patients. We conclude that intraoperative antifibrinolytic therapy with tranexamic acid does not reduce intraoperative blood loss during major cardiac surgery which contradicts popular belief. © 2017 by the Association of Clinical Scientists, Inc.

    INTRODUCTION. Antimicrobial prophylaxis decreases the surgical infections, but its indiscriminate use to favors the increment of infection rates and the bacterial resistance is much more probable in presence of antibiotics. The aim of present research was to evaluate the results of antibiotic prophylaxis in the otorhinolaryngology elective major surgery. METHODS. A retrospective-descriptive research was made on the prophylactic use of antibiotics in this type of surgery in the Otorhinolaryngology Service of the ''Comandant Manuel Fajardo'' during 6 years (2001-2006). Sample included 661 patients and the following variables were studied: sex, age and therapeutic response criteria (satisfactory and non-satisfactory). According to the intervention complexity oral antibiotic or parenteral prophylaxis was administered carrying out a surgical hound site culture. RESULTS. There was a predominance of male sex (54,1%) and the 31 and 62 age group. The 41,90% of patients operated on required antibiotic prophylaxis. The was a 7,9% of surgical wound infections. The more frequent microorganisms were Pseudomonas aeruginosa, Enterobacter and Escherichia. In head and neck oncology surgeries infection average was high (42,3%). Torpid course was due to concurrence of infection risk factors. There were neither adverse events nor severe complications. CONCLUSIONS. In Otorhinolaryngology, antimicrobial prophylaxis works against a wide variety of microorganisms but not in the Oncology surgeries. (author)

    BACKGROUND Despite national emphasis on care coordination, little is known about how fragmentation affects cancer surgery outcomes. Our study examines a specific form of fragmentation in post-discharge care—readmission to a hospital different from the location of the operation—and evaluates its causes and consequences among patients readmitted after major cancer surgery. STUDY DESIGN We used the State Inpatient Database of California (2004 to 2011) to identify patients who had major cancer surgery and their subsequent readmissions. Logistic models were used to examine correlates of non-index readmissions and to assess associations between location of readmission and outcomes, measured by in-hospital mortality and repeated readmission. RESULTS Of 9,233 readmissions within 30 days of discharge after major cancer surgery, 20.0% occurred in non-index hospitals. Non-index readmissions were associated with emergency readmission (odds ratio [OR] = 2.63; 95% CI, 2.26–3.06), rural residence (OR = 1.81; 95% CI, 1.61–2.04), and extensive procedures (eg hepatectomy vs proctectomy; OR = 2.77; CI, 2.08–3.70). Mortality was higher during non-index readmissions than index readmissions independent of patient, procedure, and hospital factors (OR = 1.31; 95% CI, 1.03–1.66), but was mitigated by adjusting for conditions present at readmission (OR = 1.24; 95% CI, 0.98–1.58). Non-index readmission predicted higher odds of repeated readmission within 60 days of discharge from the first readmission (OR = 1.16; 95% CI, 1.02–1.32), independent of all covariates. CONCLUSIONS Non-index readmissions constitute a substantial proportion of all readmissions after major cancer surgery. They are associated with more repeated readmissions and can be caused by severe surgical complications and increased travel burden. Overcoming disadvantages of non-index readmissions represents an opportunity to improve outcomes for patients having major cancer surgery. PMID:27016905

    The diagnosis of spinal infection, with or without implants, has been a challenge for physicians for many years. Spinal infections are now being recognised more frequently, owing to aging of the population and the increasing use of spinal-fusion surgery. The diagnosis in many cases is delayed, and this may result in permanent neurological damage or even death. Laboratory evidence of infection is variable. Conventional radiography and radionuclide bone imaging lack both sensitivity and specificity. Neither in vitro labelled leucocyte scintigraphy nor {sup 99m}Tc-anti-granulocyte antibody scintigraphy is especially useful, because of the frequency with which spinal infection presents as a non-specific photopenic area on these tests. Sequential bone/gallium imaging and {sup 67}Ga-SPECT are currently the radionuclide procedures of choice for spinal osteomyelitis, but these tests lack specificity, suffer from poor spatial resolution and require several days to complete. [{sup 18}F]Fluoro-2-deoxy-D-glucose (FDG) PET is a promising technique for diagnosing spinal infection, and has several potential advantages over conventional radionuclide tests. The study is sensitive and is completed in a single session, and image quality is superior to that obtained with single-photon emitting tracers. The specificity of FDG-PET may also be superior to that of conventional tracers because degenerative bone disease and fractures usually do not produce intense FDG uptake; moreover, spinal implants do not affect FDG imaging. However, FDG-PET images have to be read with caution in patients with instrumented spinal-fusion surgery since non-specific accumulation of FDG around the fusion material is not uncommon. In the future, PET-CT will likely provide more precise localisation of abnormalities. FDG-PET may prove to be useful for monitoring response to treatment in patients with spinal osteomyelitis. Other tracers for diagnosing spinal osteomyelitis are also under investigation, including

    2017-07-01

    An increasing number of patients develop symptomatic spinal metastasis and increasing evidence supports the benefit of surgical decompression and spinal stabilization combined with radiation therapy. However, surgery for metastatic spinal disease is known to be associated with a risk of substantial intraoperative blood loss and perioperative allogenic blood transfusion. Anemia is known to increase morbidity and mortality in patients undergoing surgery, but studies also indicate that transfusion with allogenic red blood cells (RBC) may lead to worse outcomes. To reduce intraoperative bleeding preoperative embolization has been used in selected cases suspected for hypervascular spinal metastases, but no randomized trial has examined the effect. The final decision on whether preoperative embolization should be performed is based on the preoperative digital subtraction angiography (DSA) tumor blush, and as such considered the "gold standard" for determining the vascularity of spinal metastases. Reliability studies evaluating vascularity ratings of DSA tumor blush have not been published before. This PhD thesis is based on three studies with the following aims: I. To assess whether perioperative allogenic blood transfusions in patients undergoing surgical treatment for spinal metastases independently influence patient survival (Study 1). II. To assess whether preoperative transcatheter arterial embolization of spinal metastases reduces blood loss, the need for transfusion with allogenic RBC and surgery time in the surgical treatment of patients with symptomatic metastatic spinal cord compression (Study 2). III. To describe the vascularity of metastasis causing spinal cord compression (Study 2). IV. To evaluate inter- and intra-observer agreement in the assessment of the vascularity of spinal metastases using DSA tumor blush (Study 3). In conclusion the findings of this thesis demonstrate that preoperative embolization in patients with symptomatic spinal metastasis

    Full Text Available Myocardial injury after noncardiac surgery (MINS is a newly proposed concept that is common among adults undergoing noncardiac surgery and associated with substantial mortality. We analyzed whether MINS was a risk factor for weaning failure in critical patients who underwent major abdominal surgery.This retrospective study was conducted in the Department of Critical Care Medicine of Peking University People's Hospital. The subjects were all critically ill patients who underwent major abdominal surgery between January 2011 and December 2013. Clinical and laboratory parameters during the perioperative period were investigated. Backward stepwise regression analysis was performed to evaluate MINS relative to the rate of weaning failure. Age, hypertension, chronic renal disease, left ventricular ejection fraction before surgery, Acute Physiologic and Chronic Health Evaluation II score, pleural effusion, pneumonia, acute kidney injury, duration of mechanical ventilation before weaning and the level of albumin after surgery were treated as independent variables.This study included 381 patients, of whom 274 were successfully weaned. MINS was observed in 42.0% of the patients. The MINS incidence was significantly higher in patients who failed to be weaned compared to patients who were successfully weaned (56.1% versus 36.5%; P<0.001. Independent predictive factors of weaning failure were MINS, age, lower left ventricular ejection fraction before surgery and lower serum albumin level after surgery. The MINS odds ratio was 4.098 (95% confidence interval, 1.07 to 15.6; P = 0.04. The patients who were successfully weaned had shorter hospital stay lengths and a higher survival rate than those who failed to be weaned.MINS is a risk factor for weaning failure from mechanical ventilation in critical patients who have undergone major abdominal surgery, independent of age, lower left ventricular ejection fraction before surgery and lower serum albumin levels after

    Spinal kyphotic deformity occasionally results in gastroesophageal reflux disease (GERD). The effects of acid reflux on the esophagus in kyphotic patients are unclear, however, and it is unknown whether acid reflux, endoscopic GERD, and reflux-related symptoms improve following surgical spinal correction in these patients. Herein, we investigated the characteristics of GERD in kyphotic patients and the improvement in GERD following surgical correction. In 48 patients with severe kyphotic deformity scheduled for surgical spinal correction, we conducted esophagogastroduodenoscopy, 24-h pH monitoring and three questionnaire surveys, including the frequency scale for the symptoms of GERD (FSSG). We repeated these measurements after surgical correction and compared pre- and post-surgery values. Of 48 patients, 70.8% [95% CI: 55.9-83.0%, 34/48] had endoscopically evaluated esophageal mucosal injury. Regarding pH before surgery, 64.9% (CI: 47.5-79.8%, 24/37) had abnormal acid reflux (intraesophageal pH reflux decreased from 66.7% (95% CI: 41.0-86.7%) to 33.3% (95% CI: 13.3-59.0%) (P = 0.045). Surgical spinal correction in kyphosis patients improves not only kyphotic deformity-related disorders but also esophageal mucosal injury, abnormal acid reflux, and reflux-related symptoms. © 2015 Japan Gastroenterological Endoscopy Society.

    To understand statewide variation in preoperative cardiology consultation prior to major vascular surgery and to determine whether consultation was associated with differences in perioperative myocardial infarction (poMI). Medical consultation prior to major vascular surgery is obtained to reduce perioperative risk. Despite perceived benefit of preoperative consultation, evidence is lacking specifically for major vascular surgery on the effect of preoperative cardiac consultation. Patient and clinical data were obtained from a statewide vascular surgery registry between January 2012 and December 2014. Patients were risk stratified by revised cardiac risk index category and compared poMI between patients who did or did not receive a preoperative cardiology consultation. We then used logistic regression analysis to compare the rate of poMI across hospitals grouped into quartiles by rate of preoperative cardiology consultation. Our study population comprised 5191 patients undergoing open peripheral arterial bypass (n = 3037), open abdominal aortic aneurysm repair (n = 332), or endovascular aneurysm repair (n = 1822) at 29 hospitals. At the patient level, after risk-stratification by revised cardiac risk index category, there was no association between cardiac consultation and poMI. At the hospital level, preoperative cardiac consultation varied substantially between hospitals (6.9%-87.5%, P 66%) had a reduction in poMI (OR, 0.52; confidence interval: 0.28-0.98; P cardiology consultation for vascular surgery varies greatly between institutions, and does not appear to impact poMI at the patient level. However, reduction of poMI was noted at the hospitals with the highest rate of preoperative cardiology consultation as well as a variety of medical services, suggesting that other hospital culture effects play a role.

    Background. It is believed that the severely disturbed night-time sleep architecture after surgery is associated with increased cardiovascular morbidity with rebound of rapid eye movement (REM). The daytime sleep pattern of patients after major general surgery has not been investigated before. We...... nights after operation. Sleep was scored independently by two blinded observers and the recordings were reported as awake, light sleep (LS, stages I and II), slow wave sleep (SWS, stages III and IV), and REM sleep. Results. There was significantly increased REM sleep (P=0.046), LS (P=0.020), and reduced...... time awake (P=0.016) in the postoperative daytime period compared with the preoperative daytime period. Five patients had REM sleep during the daytime after surgery. Three of these patients did not have REM sleep during the preceding postoperative night. There was significantly reduced night-time REM...

  13. Structural and Functional Substitution of Deleted Primary Sensory Neurons by New Growth from Intrinsic Spinal Cord Nerve Cells: An Alternative Concept in Reconstruction of Spinal Cord Circuits

    Full Text Available In a recent clinical report, return of the tendon stretch reflex was demonstrated after spinal cord surgery in a case of total traumatic brachial plexus avulsion injury. Peripheral nerve grafts had been implanted into the spinal cord to reconnect to the peripheral nerves for motor and sensory function. The dorsal root ganglia (DRG containing the primary sensory nerve cells had been surgically removed in order for secondary or spinal cord sensory neurons to extend into the periphery and replace the deleted DRG neurons. The present experimental study uses a rat injury model first to corroborate the clinical finding of a re-established spinal reflex arch, and second, to elucidate some of the potential mechanisms underlying these findings by means of morphological, immunohistochemical, and electrophysiological assessments. Our findings indicate that, after spinal cord surgery, the central nervous system sensory system could replace the traumatically detached original peripheral sensory connections through new neurite growth from dendrites.

    Full Text Available ABSTRACT Objective: Selective dorsal rhizotomy (SDR used for spasticity treatment could worsen or develop spinal deformities. Our goal is to describe spinal deformities seen in patients with cerebral palsy (CP after being treated by SDR. Methods: Retrospective study of patients operated on (SDR between January/1999 and June/2012. Inclusion criteria: spinal Rx before SDR surgery, spinography, and assessment at follow-up. We evaluated several factors emphasizing level and type of SDR approach, spinal deformity and its treatment, final Risser, and follow-up duration. Results: We found 7 patients (6 males: mean age at SDR 7.56 years (4.08-11.16. Mean follow-up: 6.64 years (2.16-13, final age: 14.32 years (7.5-19. No patient had previous deformity. GMFCS: 2 patients level IV, 2 level III, 3 level II. Initial walking status: 2 community walkers, 2 household walkers, 2 functional walkers, 1 not ambulant, at the follow-up, 3 patients improved, and 4 kept their status. We found 4 TL/L laminotomies, 2 L/LS laminectomies, and 1 thoracic laminectomy. Six spinal deformities were observed: 2 sagittal, 3 mixed, and 1 scoliosis. There was no association among the type of deformity, final gait status, topographic type, GMFCS, age, or SDR approach. Three patients had surgery indication for spinal deformity at skeletal maturity, while those patients with smaller deformities were still immature (Risser 0 to 2/3 although with progressive curves. Conclusions: After SDR, patients should be periodically evaluated until they reach Risser 5. The development of a deformity does not compromise functional results but adds morbidity because it may require surgical treatment.

    Full Text Available We report Ogilvie′s syndrome following posterior spinal arthrodesis on a patient with thoracic and lumbar scoliosis associated with intraspinal anomalies. Postoperative paralytic ileus can commonly complicate scoliosis surgery. Ogilvie′s syndrome as a cause of abdominal distension and pain has not been reported following spinal deformity correction and can mimic post-surgical ileus. 12 year old female patient with double thoracic and lumbar scoliosis associated with Arnold-Chiari 1 malformation and syringomyelia. The patient underwent posterior spinal fusion from T 4 to L 3 with segmental pedicle screw instrumentation and autogenous iliac crest grafting. She developed abdominal distension and pain postoperatively and this deteriorated despite conservative management. Repeat ultrasounds and abdominal computer tomography scans ruled out mechanical obstruction. The clinical presentation and blood parameters excluded toxic megacolon and cecal volvulus. As the symptoms persisted, a laparotomy was performed on postoperative day 16, which demonstrated ragged tears of the colon and cecum. A right hemi-colectomy followed by ileocecal anastomosis was required. The pathological examination of surgical specimens excluded inflammatory bowel disease and vascular abnormalities. The patient made a good recovery following bowel surgery and at latest followup 3.2 years later she had no abdominal complaints and an excellent scoliosis correction. Ogilvie′s syndrome should be included in the differential diagnosis of postoperative ileus in patients developing prolonged unexplained abdominal distension and pain after scoliosis correction. Early diagnosis and instigation of conservative management can prevent major morbidity and mortality due to bowel ischemia and perforation.

    The aim of this paper is to describe and evaluate the benefits of epidural anesthesia in major surgery neonatal. We have performed a matched case-control (2:1) study of patients undergoing neonatal major surgery (NMSs) who received intra-and postoperative epidural anesthesia (EA) and controls with conventional general anesthesia. The matching criteria were age, weight and baseline pathology. EA was administered by caudal puncture and epidural catheter placed with ultrasound support. Levobupivacaine was selected as anesthetic drug. The time to extubation, intestinal transit time, type of analgesia and complications were studied. This study is based on 11 cases (2 esophageal atresia, 2 diaphragmatic hernias, 1 necrotizing enterocolitis, 3 intestinal atresia, 2 anorectal malformation and 1 bladder exstrophy) and 22 controls. We observed statistically significant differences in time to extubation (95% CI OR 12 1.99 to 72.35; Chi2 p = 0.004, Mann U Whytney p = 0.013) and intestinal transit time (Mann Whitney U p analgesia. Therefore we believe that the intra-and postoperative EA helps improve postoperative management in neonates and should be preferred in centers where this technique is available.

    To summarize the incidence and spectrum of spinal cord-related complications in patients of tuberculous meningitis. Reports from multiple countries were included. An extensive review of the literature, published in English, was carried out using Scopus, PubMed and Google Scholar databases. Tuberculous meningitis frequently affects the spinal cord and nerve roots. Initial evidence of spinal cord involvement came from post-mortem examination. Subsequent advancement in neuroimaging like conventional lumbar myelography, computed tomographic myelography and gadolinium-enhanced magnetic resonance-myelography have contributed immensely. Spinal involvement manifests in several forms, like tuberculous radiculomyelitis, spinal tuberculoma, myelitis, syringomyelia, vertebral tuberculosis and very rarely spinal tuberculous abscess. Frequently, tuberculous spinal arachnoiditis develops paradoxically. Infrequently, spinal cord involvement may even be asymptomatic. Spinal cord and spinal nerve involvement is demonstrated by diffuse enhancement of cord parenchyma, nerve roots and meninges on contrast-enhanced magnetic resonance imaging. High cerebrospinal fluid protein content is often a risk factor for arachnoiditis. The most important differential diagnosis of tuberculous arachnoiditis is meningeal carcinomatosis. Anti-tuberculosis therapy is the main stay of treatment for tuberculous meningitis. Higher doses of corticosteroids have been found effective. Surgery should be considered only when pathological confirmation is needed or there is significant spinal cord compression. The outcome in these patients has been unpredictable. Some reports observed excellent recovery and some reported unfavorable outcomes after surgical decompression and debridement. Tuberculous meningitis is frequently associated with disabling spinal cord and radicular complications. Available treatment options are far from satisfactory.

    Chan, Andrew K; Winkler, Ethan A; Jacques, Line

    2016-07-01

    OBJECTIVE Cervical spinal cord stimulation (cSCS) is used to treat pain of the cervical region and upper extremities. Case reports and small series have shown a relatively low risk of complication after cSCS, with only a single reported case of perioperative spinal cord injury in the literature. Catastrophic cSCS-associated spinal cord injury remains a concern as a result of underreporting. To aid in preoperative counseling, it is necessary to establish a minimum rate of spinal cord injury and surgical complication following cSCS. METHODS The Nationwide Inpatient Sample (NIS) is a stratified sample of 20% of all patient discharges from nonfederal hospitals in the United States. The authors identified discharges with a primary procedure code for spinal cord stimulation (ICD-9 03.93) associated with a primary diagnosis of cervical pathology from 2002 to 2011. They then analyzed short-term safety outcomes including the presence of spinal cord injury and neurological, medical, and general perioperative complications and compared outcomes using univariate analysis. RESULTS Between 2002 and 2011, there were 2053 discharges for cSCS. The spinal cord injury rate was 0.5%. The rates of any neurological, medical, and general perioperative complications were 1.1%, 1.4%, and 11.7%, respectively. There were no deaths. CONCLUSIONS In the largest series of cSCS, the risk of spinal cord injury was higher than previously reported (0.5%). Nonetheless, this procedure remains relatively safe, and physicians may use these data to corroborate the safety of cSCS in an appropriately selected patient population. This may become a key treatment option in an increasingly opioid-dependent, aging population.

    2015-12-01

    To evaluate the incidence and risk factors for adjacent segment pathology (ASP) after anterior cervical spinal surgery. Fourteen patients (12 male, mean age 47.1 years) who underwent single-level cervical disk arthroplasty (CDA group) and 28 case-matched patients (24 male, mean age 53.6 years) who underwent single-level anterior cervical discectomy and fusion (ACDF group) were included. Presence of radiologic ASP (RASP) was based on observed changes in anterior osteophytes, disks, and calcification of the anterior longitudinal ligament on lateral radiographs. The mean follow-up period was 43.4 months in the CDA group and 44.6 months in the ACDF group. At final follow-up, ASP was observed in 5 (35.7%) CDA patients and 16 (57.1%) ACDF patients (p = 0.272). The interval between surgery and ASP development was 33.8 months in the CDA group and 16.3 months in the ACDF group (p = 0.046). The ASP risk factor analysis indicated postoperative cervical angle at C3-7 being more lordotic in non-ASP patients in both groups. Restoration of lordosis occurred in the CDA group regardless of the presence of ASP, but heterotopic ossification development was associated with the presence of ASP in the CDA group. And the CDA group had significantly greater clinical improvements than those in the ACDF group when ASP was present. In both CDA and ACDF patients, RASP developed, but CDA was associated with a delay in ASP development. A good clinical outcome was expected in CDA group, even when ASP developed. Restoration of cervical lordosis was an important factor in anterior cervical spine surgery.

    Review of literature. To review and analyze the evolution of cervical spine surgery from ancient times to current practice. The aim is to present an accessible overview, primarily intended for a broad readership. Descriptive literature review and analysis of the development of cervical spine surgery from the prehistoric era until today. The first evidence for surgical treatment of spinal disorders dates back to approximately 1500 BC. Conservative approaches to treatment have been the hallmark for thousands of years, but over the past 50 years progress has been rapid. We illustrate how nations have added elements to this complex subject and how knowledge has surpassed borders and language barriers. Transferral of knowledge occurred from Babylon (Bagdad) to Old Egypt, to the Greek and Roman empires and finally via the Middle East (Bagdad and Damascus) back to Europe. Recent advances in the field of anesthesia, imaging and spinal instrumentation have changed long-standing nihilism in the treatment of cervical spine pathologies to the current practice of advanced reconstructive surgery of the cervical spine. A critical approach to the evaluation of benefits and complications of these advanced surgical techniques for treatment of cervical spine disorders is required. Advances in surgery now permit full mechanical reconstruction of the cervical spine. However, despite substantial experimental progress, spinal cord repair and restoration of lost functions remain a challenge. Modern surgeons are still looking for the best way to manage spine disorders.

    The optimal timing for surgery for patients with spinal cord injury without radiographic evidence of trauma (SCIWORET) remains unclear. This is especially true in the elderly, given that most studies are done with younger patients to avoid age-related comorbidities. We aimed to compare the efficacy of early (24 hours postinjury) surgery in patients with SCIWORET aged ≥65 years. We identified patients aged ≥65 years who underwent surgery for SCIWORET between January 1995 and February 2016. The primary outcome was a change in the Japanese Orthopaedic Association (JOA) score at discharge, with a recovery of >50% defined as a favorable neurologic outcome. Logistic regression analysis was performed, and model fit was assessed using the Hosmer-Lemeshow test. Eighty patients aged ≥65 years with SCIWORET underwent surgery were enrolled. Favorable neurologic outcomes were seen in 43.3% of those who underwent early surgery, but only in 18.0% of those who underwent late surgery. Logistic regression analysis, adjusted for age, sex, comorbidities (Charlson Comorbidity Index), and JOA score, revealed that early surgery independently predicted favorable outcomes (odds ratio, 4.06; 95% confidence interval, 1.25-13.20), with excellent calibration (Hosmer-Lemeshow, P = 0.857). The present study indicated that early surgery within 24 hours of injury for elderly patients with SCIWORET could lead to more favorable neurologic improvements. We believe that chronological age alone should not be considered sufficient justification to deny patients early surgical decompression for SCIWORET. Copyright © 2017 Elsevier Inc.

    Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml -1 mixed with 0.5 ml of fentanyl 50 μg ml -1 . Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery. The patient was reviewed 2 days postoperatively in ward. The thoracic spinal anesthetia was performed easily in the patient. Some discomfort which was readily treated with 1mg midazolam and 20 mg ketamine intravenously. There was no neurological deficit and hemodynamic parameters were in normal range intra and post-operatively and recovery was uneventful. We used a narrow gauze (26G) spinal needle which minimized the trauma to the patient and the chances of PDPH, which was more if 16 or 18G epidural needle had been used and could have increased further if there have been accidental dura puncture. Also using spinal anesthesia was economical although it should be done cautiously as we are giving spinal anesthesia above the level of termination of spinal cord.

      Abstracts The description of an experimental model of lumbar spinal stenosis on 20 rats. The experiment was symmetrical dissection of arc plates to the inside thin cortical layer plates, and then dissection of the latter. The middle part of the arc with the spinous processes of the vertebrae is separated from the rest of the arc, and articular processes. The separated middle part of the arc with yellow ligament is shifted in the ventral direction, reducing the size of the cavity of the spinal canal and fix the contacting bone edges with bone cement. Degenerative changes of the nerve roots were evaluated histologically by endoneural and epineural changes using a 7-point scale of G. Byrond and others. In the studied group of animals 7 days after spinal canal stenosis simulations appeared degenerative changes of nerve fibers, but the degree is low, and there is virtually no endoneural inflammation. The epineurium determined expressed or gross changes, indicating epineural inflammatory processes. After 1 month. There appeared dystrophic and degenerative changes of nerve fibers of the overwhelming majority (over 75%. At a later date (3 months, endoneural change remained practically the same as in the 1th month after surgery, epineural violations were preserved, there were groups and single fibroblasts as a sign of epineural fibrosis, as well as portions of connective tissue neoplasms and hyalinosis.   Keywords: lumbar spinal stenosis, an experimental model.

  9. Predictive Value of C-Reactive Protein for Major Complications after Major Abdominal Surgery: A Systematic Review and Pooled-Analysis.

    Jennifer Straatman

    Full Text Available Early diagnosis and treatment of complications after major abdominal surgery can decrease associated morbidity and mortality. Postoperative CRP levels have shown a strong correlation with complications. Aim of this systematic review and pooled-analysis was to assess postoperative values of CRP as a marker for major complications and construct a prediction model.A systematic review was performed for CRP levels as a predictor for complications after major abdominal surgery (MAS. Raw data was obtained from seven studies, including 1427 patients. A logit regression model assessed the probability of major complications as a function of CRP levels on the third postoperative day. Two practical cut-offs are proposed: an optimal cut-off for safe discharge in a fast track protocol and another for early identification of patients with increased risk for major complications.A prediction model was calculated for major complications as a function of CRP levels on the third postoperative day. Based on the model several cut-offs for CRP are proposed. For instance, a two cut-off system may be applied, consisting of a safe discharge criterion with CRP levels below 75 mg/L, with a negative predictive value of 97.2%. A second cut-off is set at 215 mg/L (probability 20% and serves as a predictor of complications, indicating additional CT-scan imaging.The present study provides insight in the interpretation of CRP levels after major abdominal surgery, proposing a prediction model for major complications as a function of CRP on postoperative day 3. Cut-offs for CRP may be implemented for safe early-discharge in a fast-track protocol and, secondly as a threshold for additional examinations, such as CT-scan imaging, even in absence of clinical signs, to confirm or exclude major complications. The prediction model allows for setting a cut-off at the discretion of individual surgeons or surgical departments.

    Spinal cord injury arising during anaesthetic practice is a rare event, but one that carries a significant burden in terms of morbidity and mortality. In this article, we will review the pathophysiology of spinal cord injury. We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. The most serious causes of spinal cord injury - vertebral canal haematoma, spinal epidural abscess, meningitis and adhesive arachnoiditis - will be discussed in turn. For each condition, we draw attention to practical, evidence-based measures clinicians can undertake to reduce their incidence, or mitigate their severity. Finally, we will discuss transient neurological symptoms. Some cases of spinal cord injury during anaesthesia can be ascribed to anaesthesia itself, arising as a direct consequence of its conduct. The injury to a spinal nerve root by inaccurate and/or incautious needling during spinal anaesthesia is an obvious example. But in many cases, spinal cord injury during anaesthesia is not caused by, related to, or even associated with, the conduct of the anaesthetic. Surgical factors, whether direct (e.g. spinal nerve root damage due to incorrect pedicle screw placement) or indirect (e.g. cord ischaemia following aortic surgery) are responsible for a significant proportion of spinal cord injuries that occur concurrently with the delivery of regional or general anaesthesia. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

    Unilateral spinal anesthesia has its advantages, especially in patients undergoing outpatient basis surgeries. Low dose, slow speed of administration, and the lateral positioning make easier the unilateral distribution in spinal anesthesia. Isobaric, hyperbaric, and hypobaric solutions of bupivacaine were compared in the unilateral spinal anesthesia in patients undergoing outpatient basis orthopedic surgeries. One hundred and fifty patients were randomly divided in three groups to receive 5 mg of 0.5% isobaric bupivacaine (Iso Group), 5 mg of 0.5% hyperbaric bupivacaine (Hyper Group), or 5 mg of 0.15% hypobaric bupivacaine (Hypo Group). The solutions were administered in the L3-L4 space with the patient in the lateral decubitus and remaining in this position for 20 minutes. Sensitive anesthesia was evaluated by the pin prick test. Motor blockade was determined by the modified Bromage scale. Both blockades were compared with the opposite side and among themselves. There was a significant difference between the side of the surgery and the opposite side in all three groups at 20 minutes, but the frequency of unilateral spinal anesthesia was greater with the hyperbaric and hypobaric solutions. Sensitive and motor blockades were observed in 14 patients in the Iso Group, 38 patients in the Hyper Group, and 40 patients in the Hypo Group. Patients did not develop any hemodynamic changes. Postpuncture headache and transitory neurological symptoms were not observed. Spinal anesthesia with hypobaric and hyperbaric solutions present a higher frequency of unilateral anesthesia. After 20 minutes, isobaric bupivacaine mobilized into cerebrospinal fluid (CSF) resulted in unilateral spinal anesthesia in only 28% of the patients.

    Full Text Available Waleed Al Taweel, Raouf SeyamDepartment of Urology, King Faisal Specialist Hospital and Research Center, Riyadh, Saudi ArabiaAbstract: Neurogenic bladder dysfunction due to spinal cord injury poses a significant threat to the well-being of patients. Incontinence, renal impairment, urinary tract infection, stones, and poor quality of life are some complications of this condition. The majority of patients will require management to ensure low pressure reservoir function of the bladder, complete emptying, and dryness. Management typically begins with anticholinergic medications and clean intermittent catheterization. Patients who fail this treatment because of inefficacy or intolerability are candidates for a spectrum of more invasive procedures. Endoscopic managements to relieve the bladder outlet resistance include sphincterotomy, botulinum toxin injection, and stent insertion. In contrast, patients with incompetent sphincters are candidates for transobturator tape insertion, sling surgery, or artificial sphincter implantation. Coordinated bladder emptying is possible with neuromodulation in selected patients. Bladder augmentation, usually with an intestinal segment, and urinary diversion are the last resort. Tissue engineering is promising in experimental settings; however, its role in clinical bladder management is still evolving. In this review, we summarize the current literature pertaining to the pathology and management of neurogenic bladder dysfunction in patients with spinal cord injury.Keywords: neurogenic bladder, spinal cord injury, urodynamics, intestine, intermittent catheterization

    Central neuraxial blocks (CNB: epidural, spinal and their combinations) and other spinal pain procedures can cause serious harm to the spinal cord in patients on antihaemostatic drugs or who have other risk-factors for bleeding in the spinal canal. The purpose of this narrative review is to provide a practise advisory on how to reduce risk of spinal cord injury from spinal haematoma (SH) during CNBs and other spinal pain procedures. Scandinavian guidelines from 2010 are part of the background for this practise advisory. We searched recent guidelines, PubMed (MEDLINE), SCOPUS and EMBASE for new and relevant randomised controlled trials (RCT), case-reports and original articles concerning benefits of neuraxial blocks, risks of SH due to anti-haemostatic drugs, patient-related risk factors, especially renal impairment with delayed excretion of antihaemostatic drugs, and specific risk factors related to the neuraxial pain procedures. Epidural and spinal analgesic techniques, as well as their combination provide superior analgesia and reduce the risk of postoperative and obstetric morbidity and mortality. Spinal pain procedure can be highly effective for cancer patients, less so for chronic non-cancer patients. We did not identify any RCT with SH as outcome. We evaluated risks and recommend precautions for SH when patients are treated with antiplatelet, anticoagulant, or fibrinolytic drugs, when patients' comorbidities may increase risks, and when procedure-specific risk factors are present. Inserting and withdrawing epidural catheters appear to have similar risks for initiating a SH. Invasive neuraxial pain procedures, e.g. spinal cord stimulation, have higher risks of bleeding than traditional neuraxial blocks. We recommend robust monitoring routines and treatment protocol to ensure early diagnosis and effective treatment of SH should this rare but potentially serious complication occur. When neuraxial analgesia is considered for a patient on anti

    In clinical practice, the level of sensory block in spinal anesthesia in opium abusers is lower than that in non-abusers because of adaptive changes caused by opium use. The aim of this study was to investigate the level of sensory block resulting from the intrathecal administration of 0.5% bupivacaine in opium abuser patients undergoing lower extremity and lower abdominal surgeries. A total of 100 patients who were candidates of elective lower extremity orthopedic and lower abdominal surgeries were recruited and assigned to two groups based on their history of opium addiction (Case or control). Both groups underwent the same anesthesia procedure and pinprick test was used to assess the level of anesthesia. No statistically significant difference was observed between groups regarding age, duration of the surgery, and type of surgery. The frequency of addiction was higher in males than in females. The level of sensory block at three minutes was significantly lower in the opium abuser group (P = 0.006). The mean time to achieve T10 sensory block was 10.33 ± 5.79 minutes in the opium abusers and 6.89 ± 3.88 minutes in the controls (P = 0.001). The level of the highest sensory block was lower in the opium abuser group (P = 0.002). The findings of this study suggested that after induction of spinal anesthesia with intrathecal administration of bupivacaine, chronic opium abusers would have a lower level of sensory block in comparison with patients without a history of opium abuse.

    In a prospective, double-blinded, randomized trial, we evaluated the efficacy of IV (a) dexamethasone 8 mg, (b) ondansetron 8 mg, and (c) dexamethasone 8 mg plus ondansetron 4 mg for the prevention of postoperative nausea, vomiting (PONV), and pruritus in 130 (ASA physical status I to III) patients undergoing elective major orthopedic surgery after spinal anesthesia with hyperbaric 0.5% bupivacaine and intrathecal morphine. After spinal anesthesia, patients were randomized to one of three groups. Failure of PONV prophylaxis in the 24-h postoperative period occurred more frequently in patients who received dexamethasone alone (29 of 40; 73%) compared with those who received either ondansetron alone (23 of 47; 49%) (P = 0.02) or dexamethasone plus ondansetron together (19 of 43; 44%)(P = 0.01). There was no difference in the incidence of failure of prophylaxis of pruritus (70%, 72%, and 70% in dexamethasone 8 mg, ondansetron 8 mg, and dexamethasone 8 mg plus ondansetron 4 mg, respectively) (P > 0.1) in the 24-h postoperative period. We conclude that the administration of dexamethasone 8 mg with ondansetron 4 mg has no added benefit compared with ondansetron 8 mg alone in the prophylaxis of PONV and pruritus. IMPLICATIONS: Postoperative nausea and vomiting (PONV) and pruritus are common side effects after spinal opioid administration. In this study, dexamethasone 8 mg plus ondansetron 4 mg was as effective as ondansetron 8 mg. The administration of dexamethasone alone was associated with a frequent incidence of PONV, demonstrating a lack of efficacy. This has important cost implications.

    For spinal surgery navigational system images are usually acquired before surgery with patients positioned supine. The aim of this study was to evaluate prospectively navigated procedures in spinal surgery with data acquisition by intraoperative computed tomography (iCT). CT data of 38 patients [thoracolumbar instability (n = 24), C1/2 instability (n = 6), cervicothoracic stabilization (n = 7), disk herniation (n = 1)] were acquired after positioning the patient in prone position. A sliding gantry 24 detector row CT was used for image acquisition. Data were imported to the frameless infrared-based neuronavigation station. A postprocedural CT was obtained to assess the extent of decompression and the accuracy of instrumentation. Intraoperative registration revealed computed accuracy 2 mm in 9/158 screws (5.6%), allowing immediate correction in five screws without any damage to vessels or nerves. There were three transient complications with clinical improvement in all patients. Intraoperative CT in combination with neuronavigation provides high accuracy of screw placement and thus safety for patients undergoing spinal stabilization. The procedure is rapid and easy to perform and - by replacing pre- and postoperative imaging-is not associated with additional exposure to radiation. (orig.)

    Full Text Available Abstract Background Degenerative spinal stenosis and instability requiring multilevel spine surgery has been associated with large blood losses. Factors that affect perioperative blood loss include time of surgery, surgical procedure, patient height, combined anterior/posterior approaches, number of levels fused, blood salvage techniques, and the use of anti-fibrinolytic medications. This study was done to evaluate the efficacy of tranexamic acid in reducing blood loss in spine surgery. Methods This retrospective case control study includes 97 patients who had to undergo surgery because of degenerative lumbar spinal stenosis and instability. All operations included spinal decompression, interbody fusion and posterior instrumentation (4-5 segments. Forty-six patients received 1 g tranexamic acid intravenous, preoperative and six hours and twelve hours postoperative; 51 patients without tranexamic acid administration were evaluated as a control group. Based on the records, the intra- and postoperative blood losses were measured by evaluating the drainage and cell saver systems 6, 12 and 24 hours post operation. Additionally, hemoglobin concentration and platelet concentration were reviewed. Furthermore, the number of red cell transfusions given and complications associated with tranexamic acid were assessed. Results The postoperative hemoglobin concentration demonstrated a statistically significant difference with a p value of 0.0130 showing superiority for tranexamic acid use (tranexamic acid group: 11.08 g/dl, SD: 1.68; control group: 10.29 g/dl, SD: 1.39. The intraoperative cell saver volume and drainage volume after 24 h demonstrated a significant difference as well, which indicates a less blood loss in the tranexamic acid group than the control group. The postoperative drainage volume at12 hours showed no significant differences; nor did the platelet concentration Allogenic blood transfusion (two red cell units was needed for eight patients

    Most malignancies are diagnosed in older adults who are potentially susceptible to aging-related health conditions; however, the manifestation of geriatric syndromes during surgical cancer treatment is not well quantified. Accordingly, we sought to assess the prevalence and ramifications of geriatric events during major surgery for cancer. Using Nationwide Inpatient Sample data from 2009 to 2011, we examined hospital admissions for major cancer surgery among elderly patients (ie, age ≥ 65 years) and a referent group age 55 to 64 years. From these observations, we identified geriatric events that included delirium, dehydration, falls and fractures, failure to thrive, and pressure ulcers. We then estimated the collective prevalence of these events according to age, comorbidity, and cancer site and further explored their relationship with other hospital-based outcomes. Within a weighted sample of 939,150 patients, we identified at least one event in 9.2% of patients. Geriatric events were most common among patients age ≥ 75 years, with a Charlson comorbidity score ≥ 2, and who were undergoing surgery for cancer of the bladder, ovary, colon and/or rectum, pancreas, or stomach (P geriatric event had a greater likelihood of concurrent complications (odds ratio [OR], 3.73; 95% CI, 3.55 to 3.92), prolonged hospitalization (OR, 5.47; 95% CI, 5.16 to 5.80), incurring high cost (OR, 4.97; 95% CI, 4.58 to 5.39), inpatient mortality (OR, 3.22; 95% CI, 2.94 to 3.53), and a discharge disposition other than home (OR, 3.64; 95% CI, 3.46 to 3.84). Many older patients who receive cancer-directed surgery experience a geriatric event, particularly those who undergo major abdominal surgery. These events are linked to operative morbidity, prolonged hospitalization, and more expensive health care. As our population ages, efforts focused on addressing conditions and complications that are more common in older adults will be essential to delivering high-quality cancer care. © 2016 by

    2016-01-01

    The incidence of Malignant Spinal Cord Compression (MSCC) is thought to be increasing in the UK due to an aging population and improving cancer survivorship. The impact of such a diagnosis requires emergency treatment. In 2008 the National Institute of Clinical Excellence produced guidelines on the management of MSCC which includes a recommendation to assess spinal instability. However, a lack of guidelines to assess spinal instability in oncology patients is widely acknowledged. This can result in variations in the management of care for such patients. A spinal instability assessment can influence optimum patient care (bed rest or encouraged mobilisation) and inform the best definitive treatment modality (surgery or radiotherapy) for an individual patient. The aim of this systematic review is to attempt to identify a consensus definition of spinal instability and methods by which it can be classified. - Highlights: • A lack of guidance on metastatic spinal instability results in variations of care. • Definitions and assessments for spinal instability are explored in this review. • A Spinal Instability Neoplastic Scoring (SINS) system has been identified. • SINS could potentially be adopted to optimise and standardise patient care.

    Full Text Available Abstract Meeting patients' nutritional requirements and preventing malnutrition is a challenge following major surgical procedures. The role of ghrelin in nutritional recovery after non-gastrointestinal major surgery is unknown. We used coronary artery bypass grafting (CABG as an example of anticipated good recovery post major surgery. Seventeen patients undergoing CABG (mean ± SEM: 70.1 ± 2.2 yrs, BMI 29.1 ± 1.4 kg/m2, 15 male underwent fasting and postprandial (45 mins after standard test breakfast blood sampling pre-operatively (day 0, post-operatively (day 6 and at follow-up (day 40. Changes in food intake, biochemical and anthropometric markers of nutritional status were recorded. A comparison was made to 17 matched healthy controls (70.6 ± 2.3 yrs, BMI 28.4 ± 1.3 kg/m2. We observed significantly increased post-operative and follow-up fasting ghrelin concentrations compared with pre-operatively (pre-op. 402 ± 42 pmol/L vs post-op. 642 ± 97 pmol/L vs follow-up 603 ± 94 pmol/L (ANOVA p p Our data support the hypothesis that prolonged changes in fasting and postprandial plasma ghrelin concentrations are associated with impaired nutritional recovery after CABG. These findings reinforce the need to investigate ghrelin in other patients groups undergoing major surgery.

    Systematic review. The purpose of this review was to attempt to answer the following 2 clinical questions: (1) Does minimal access tubular assisted spine surgery (MAS) decrease the rate of complications in posterior thoracolumbar decompression and/or fusion surgery compared with traditional open techniques? (2) What strategies to reduce the risk of complications in MAS have been shown to be effective? The objective of minimal access spine surgery is to reduce damage to surrounding tissues while accomplishing the same goals as conventional surgery. Patient demand and marketing for MAS is driven by the perception of better outcomes, although the purported advantages remain unproven. Whether the risk of complications is affected by minimal access techniques is unknown. A systematic review of the English language literature was undertaken for articles published between 1990 and July 2009. Electronic databases and reference lists of key articles were searched to identify published studies that compared the rate of complications after MAS to a control group that underwent open surgery. Single-arm studies were excluded. Two independent reviewers assessed the strength of literature using GRADE criteria assessing quality, quantity, and consistency of results. Disagreements were resolved by consensus. From the 361 articles identified, 13 met a priori criteria and were included for review. All of the studies evaluated only lumbar spine surgery. The single large randomized study showed less favorable results for MAS discectomy, but no significant difference in complication rates. The quality of the other studies, particularly for fusion surgery, was low. Overall, the rates of reoperation, dural tear, cerebrospinal fluid leak, nerve injury, and infection occurred in similar proportions between MAS and open surgery. Blood loss was reduced in MAS fusion; however, the quality of those studies was very low. Operation time and hospital length of stay was variable across studies

    In recent years, spinal surgery has incorporated the many advantages of navigation techniques to facilitate the placement of pedicle screws during osteosynthesis, mainly for degenerative diseases. However, spinal intradural tumors are not clearly visible by intraoperative fluoroscopy or computed tomography scans, thereby making navigation necessary. To evaluate the use of spinal navigation for the removal of intradural and spinal cord tumors using spinal magnetic resonance imaging (MRI) merged with intraoperative 3-dimensional (3-D) fluoro images. After fixing the patient reference frame on the spinous process, the 3-D fluoro images were obtained in the surgical room. Using this image as the reference, the preoperative volumetric MRI images and intraoperative 3-D fluoro images were merged using automated software or manually. From January to July 2016, we performed 10 navigated procedures for intradural spinal tumors by merging MRI and 3-D fluoro images. Nine patients had an intradural extramedullary tumor, 6 had neurinomas, and 3 had meningiomas; 1 patient had an intramedullary spinal cord metastasis. The surgically demonstrated benefits of spinal navigation for the removal of intradural tumors include the decreased risk of surgery at the wrong spinal level, a minimal length of skin incision and muscle strip, and a reduction in bone removal extension. Furthermore, this technique offers the advantage of opening the dura as much as is necessary and, in the case of intrinsic spinal cord tumors, it allows the tumor to be centered. Otherwise, this would not be visible, thus enabling the precise level and the posterior midline sulcus to be determined when performing a mielotomy.

The neuronal organization of the dorsal horn is still poorly understood, although recent studies have defined several distinct populations among the interneurons, which account for most of its constituent neurons. All primary afferents, and the great majority of neurons in laminae I–III are glutamatergic, and a major factor limiting our understanding of the synaptic circuitry has been the difficulty i...

  8. Transient long thoracic nerve injury during posterior spinal fusion for adolescent idiopathic scoliosis: A report of two cases

    Directory of Open Access Journals (Sweden)

    Athanasios I Tsirikos

    2013-01-01

    Full Text Available We present the transient long thoracic nerve (LTN injury during instrumented posterior spinal arthrodesis for idiopathic scoliosis. The suspected mechanism of injury, postoperative course and final outcome is discussed. The LTN is susceptible to injury due to its long and relatively superficial course across the thoracic wall through direct trauma or tension. Radical mastectomies with resection of axillary lymph nodes, first rib resection to treat thoracic outlet syndrome and cardiac surgery can be complicated with LTN injury. LTN injury producing scapular winging has not been reported in association with spinal deformity surgery. We reviewed the medical notes and spinal radiographs of two adolescent patients with idiopathic scoliosis who underwent posterior spinal arthrodesis and developed LTN neuropraxia. Scoliosis surgery was uneventful and intraoperative spinal cord monitoring was stable throughout the procedure. Postoperative neurological examination was otherwise normal, but both patients developed winging of the scapula at 4 and 6 days after spinal arthrodesis, which did not affect shoulder function. Both patients made a good recovery and the scapular winging resolved spontaneously 8 and 11 months following surgery with no residual morbidity. We believe that this LTN was due to positioning of our patients with their head flexed, tilted and rotated toward the contralateral side while the arm was abducted and extended. The use of heavy retractors may have also applied compression or tension to the nerve in one of our patients contributing to the development of neuropraxia. This is an important consideration during spinal deformity surgery to prevent potentially permanent injury to the nerve, which can produce severe shoulder dysfunction and persistent pain.

  9. Pediatric spinal infections

    Full Text Available The infections of the spinal axis in children are rare when compared with adults. They encompass a large spectrum of diseases ranging from relatively benign diskitis to spinal osteomyleitis and to the rapidly progressive, rare, and potentially devastating spinal epidural, subdural, and intramedullary spinal cord infections. We present a comprehensive review of the literature pertaining to these uncommon entities, in light of our experience from northern India. The most prevalent pediatric spinal infection in Indian scenario is tuberculosis, where an extradural involvement is more common than intradural. The craniovertebral junction is not an uncommon site of involvement in children of our milieu. The majority of pyogenic infections of pediatric spine are associated with congenital neuro-ectodermal defects such as congenital dermal sinus. The clinico-radiological findings of various spinal infections commonly overlap. Hence the endemicity of certain pathogens should be given due consideration, while considering the differential diagnosis. However, early suspicion, rapid diagnosis, and prompt treatment are the key factors in avoiding neurological morbidity and deformity in a growing child.

    Patient-reported outcomes (PRO) represent an important measure of cancer therapy effect. For patients with metastatic epidural spinal cord compression (MESCC), hybrid therapy using separation surgery and stereotactic radiosurgery preserves neurologic function and provides tumor control. There is currently a paucity of data reporting PRO after such combined modality therapy for MESCC. Delineation of hybrid surgery-radiosurgery therapy effect on PRO validates the hybrid approach as an effective therapy resulting in meaningful symptom relief. Brief Pain Inventory (BPI) and MD Anderson Symptom Inventory-Spine Tumor (MDASI-SP), PROs validated in the cancer population, were prospectively collected. Patients with MESCC who underwent separation surgery followed by stereotactic radiosurgery were included. Separation surgery included a posterolateral approach without extensive cytoreductive tumor excision. A median postoperative radiosurgery dose of 2700 cGy was delivered. The change in PRO 3 months after the hybrid therapy represented the primary study outcome. Preoperative and postoperative evaluations were analyzed using the Wilcoxon signed-rank test for matched pairs. One hundred eleven patients were included. Hybrid therapy resulted in a significant reduction in the BPI items "worst" and "right now" pain ( P < .0001), and in all BPI constructs (severity, interference with daily activities, and pain experience, P < .001). The MDASI-SP demonstrated reduction in spine-specific pain severity and interference with general activity ( P < .001), along with decreased symptom interference ( P < .001). Validated PRO instruments showed that in patients with MESCC, hybrid therapy with separation surgery and radiosurgery results in a significant decrease in pain severity and symptom interference. These prospective data confirm the benefit of hybrid therapy for treatment of MESCC and should facilitate referral of patients with MESCC for surgical evaluation.

    Assessment of dehydration in the preoperative setting is of potential clinical value. The present study uses urine analysis and plasma volume kinetics, which have both been validated against induced changes in body water in volunteers, to study the incidence and severity of dehydration before open abdominal surgery begins. Thirty patients (mean age 64 years) had their urine analysed before major elective open abdominal surgery for colour, specific weight, osmolality and creatinine. The results were scored and the mean taken to represent a 'dehydration index'. Thereafter, the patients received an infusion of 5 ml/kg of Ringer's acetate intravenously for over 15 min. Blood was sampled for 70 min and the blood haemoglobin concentration used to estimate the plasma volume kinetics. Distribution of fluid occurred more slowly (P dehydrated as compared with euhydrated patients. The dehydration index indicated that the fluid deficit in these patients corresponded to 2.5% of the body weight, whereas the deficit in the others was 1%. In contrast, the 11 patients who later developed postoperative nausea and vomiting had a very short elimination half-life, only 9 min (median, P dehydration before major surgery was modest as evidenced both by urine sampling and volume kinetic analysis. © 2014 The Acta Anaesthesiologica Scandinavica Foundation.

    The clinical significance of pathologies of the spinal dura is often unclear and their management controversial. To classify spinal dural pathologies analogous to vascular aneurysms, present their symptoms and surgical results. Among 1519 patients with spinal space-occupying lesions, 66 patients demonstrated dural pathologies. Neuroradiological and surgical features were reviewed and clinical data analyzed. Saccular dural diverticula (type I, n = 28) caused by defects of both dural layers, dissections between dural layers (type II, n = 29) due to defects of the inner layer, and dural ectasias (type III, n = 9) related to structural changes of the dura were distinguished. For all types, symptoms consisted of local pain followed by signs of radiculopathy or myelopathy, while one patient with dural ectasia presented a low-pressure syndrome and 10 patients with dural dissections additional spinal cord herniation. Type I and type II pathologies required occlusion of their dural defects via extradural (type I) or intradural (type II) approaches. For type III pathologies of the dural sac no surgery was recommended. Favorable results were obtained in all 14 patients with type I and 13 of 15 patients with type II pathologies undergoing surgery. The majority of dural pathologies involving root sleeves remain asymptomatic, while those of the dural sac commonly lead to pain and neurological symptoms. Type I and type II pathologies were treated with good long-term results occluding their dural defects, while ectasias of the dural sac (type III) were managed conservatively.

    Full Text Available In humans, spinal cord lesions induce not only major motor and neurovegetative deficits but also severe neuropathic pain which is mostly resistant to classical analgesics. Better treatments can be expected from precise characterization of underlying physiopathological mechanisms. This led us to thoroughly investigate (i mechanical and thermal sensory alterations, (ii responses to acute treatments with drugs having patent or potential anti-allodynic properties and (iii the spinal/ganglion expression of transcripts encoding markers of neuronal injury, microglia and astrocyte activation in rats that underwent complete spinal cord transection (SCT. SCT was performed at thoracic T8-T9 level under deep isoflurane anaesthesia, and SCT rats were examined for up to two months post surgery. SCT induced a marked hyper-reflexia at hindpaws and strong mechanical and cold allodynia in a limited (6 cm2 cutaneous territory just rostral to the lesion site. At this level, pressure threshold value to trigger nocifensive reactions to locally applied von Frey filaments was 100-fold lower in SCT- versus sham-operated rats. A marked up-regulation of mRNAs encoding ATF3 (neuronal injury and glial activation markers (OX-42, GFAP, P2×4, P2×7, TLR4 was observed in spinal cord and/or dorsal root ganglia at T6-T11 levels from day 2 up to day 60 post surgery. Transcripts encoding the proinflammatory cytokines IL-1β, IL-6 and TNF-α were also markedly but differentially up-regulated at T6-T11 levels in SCT rats. Acute treatment with ketamine (50 mg/kg i.p., morphine (3-10 mg/kg s.c. and tapentadol (10-20 mg/kg i.p. significantly increased pressure threshold to trigger nocifensive reaction in the von Frey filaments test, whereas amitriptyline, pregabalin, gabapentin and clonazepam were ineffective. Because all SCT rats developed long lasting, reproducible and stable allodynia, which could be alleviated by drugs effective in humans, thoracic cord transection might be a

    Full Text Available Solitary epidural space metastasis of a malignant tumor is rare. We encountered a 79-year-old male patient with solitary metastatic epidural tumor who developed paraplegia and dysuria. The patient had undergone total gastrectomy for gastric cancer followed by chemotherapy 8 months priorly. The whole body was examined for suspected metastatic spinal tumor, but no metastases of the spine or important organs were observed, and a solitary mass was present in the thoracic spinal epidural space. The mass was excised for diagnosis and treatment and was histopathologically diagnosed as metastasis from gastric cancer. No solitary metastatic epidural tumor from gastric cancer has been reported in English. Among the Japanese, 3 cases have been reported, in which the outcome was poor in all cases and no definite diagnosis could be made before surgery in any case. Our patient developed concomitant pneumonia after surgery and died shortly after the surgery. When a patient has a past medical history of malignant tumor, the possibility of a solitary metastatic tumor in the epidural space should be considered.

    Observational. To estimate the radiation dose imparted to patients during typical thoracolumbar spinal surgical scenarios. Minimally invasive techniques continue to become more common in spine surgery. Computer-assisted navigation systems coupled with intraoperative cone-beam computed tomography (CT) represent one such method used to aid in instrumented spinal procedures. Some studies indicate that cone-beam CT technology delivers a relatively low dose of radiation to patients compared with other x-ray-based imaging modalities. The goal of this study was to estimate the radiation exposure to the patient imparted during typical posterior thoracolumbar instrumented spinal procedures, using intraoperative cone-beam CT and to place these values in the context of standard CT doses. Cone-beam CT scans were obtained using Medtronic O-arm (Medtronic, Minneapolis, MN). Thermoluminescence dosimeters were placed in a linear array on a foam-plastic thoracolumbar spine model centered above the radiation source for O-arm presets of lumbar scans for small or large patients. In-air dosimeter measurements were converted to skin surface measurements, using published conversion factors. Dose-length product was calculated from these values. Effective dose was estimated using published effective dose to dose-length product conversion factors. Calculated dosages for many full-length procedures using the small-patient setting fell within the range of published effective doses of abdominal CT scans (1-31 mSv). Calculated dosages for many full-length procedures using the large-patient setting fell within the range of published effective doses of abdominal CT scans when the number of scans did not exceed 3. We have demonstrated that single cone-beam CT scans and most full-length posterior instrumented spinal procedures using O-arm in standard mode would likely impart a radiation dose within the range of those imparted by a single standard CT scan of the abdomen. Radiation dose increases

    Prospective, multi-centre, multi-specialty medical notes review and patient interview. The consenting process is an important communication tool which also carries medico-legal implications. While written consent is a pre-requisite before spinal surgery in the UK, the standard and effectiveness of the process have not been assessed previously. This study assesses standard of written consent for elective lumbar decompressive surgery for degenerative disc disease across different regions and specialties in the UK; level of patient recall of the consent content; and identifies factors which affect patient recall. Consent forms of 153 in-patients from 4 centres a, b, c, d were reviewed. Written documentation of intended benefits, alternative treatments and operative risks was assessed. Of them, 108 patients were interviewed within 24 h before or after surgeries to assess recall. The written documentation rates of the operative risks showed significant inter-centre variations in haemorrhage and sphincter disturbance (P = 0.000), but not for others. Analysis of pooled data showed variations in written documentation of risks (P recall of these risks, there was no inter-centre variation. Patients' recall of paralysis as a risk was highest (50.9%) and that of recurrence was lowest (6.5%). Patients recalled risks better than those ≥65, significantly so for infection (29.9 vs 9.7%, P = 0.027). Patients consented >14 days compared to recall for paralysis (65.2 vs 43.7%) and recurrence (17.4 vs 2.8%). Patient recall was independent of consenter grade. Overall, the standard of written consent for elective lumbar spinal decompressive surgery was sub-optimal, which was partly reflected in the poor patient recall. While consenter seniority did not affect patient recall, younger age and longer consent-to-surgery time improved it.

    Background and Aims: Preemptive analgesia is an antinociceptive treatment that prevents establishment of altered processing of afferent input. Pregabalin has been claimed to be more effective in preventing neuropathic component of acute nociceptive pain of surgery. We conducted a study to compare the effect of oral gabapentin and pregabalin with control group for post-operative analgesia Materials and Methods: A total of 90 ASA grade I and II patients posted for elective gynecological surgeries were randomized into 3 groups (group A, B and C of 30 patients each). One hour before entering into the operation theatre the blinded drug selected for the study was given with a sip of water. Group A- received identical placebo capsule, Group B- received 600mg of gabapentin capsule and Group C — received 150 mg of pregabalin capsule. Spinal anesthesia was performed at L3-L4 interspace and a volume of 3.5 ml of 0.5% bupivacaine heavy injected over 30sec through a 25 G spinal needle. VAS score at first rescue analgesia, mean time of onset of analgesia, level of sensory block at 5min and 10 min interval, onset of motor block, total duration of analgesia and total requirement of rescue analgesia were observed as primary outcome. Hemodynamics and side effects were recorded as secondary outcome in all patients. Results: A significantly longer mean duration of effective analgesia in group C was observed compared with other groups (P < 0.001). The mean duration of effective analgesia in group C was 535.16 ± 32.86 min versus 151.83 ± 16.21 minutes in group A and 302.00 ± 24.26 minutes in group B. The mean numbers of doses of rescue analgesia in the first 24 hours in group A, B and C was 4.7 ± 0.65, 4.1 ±0.66 and 3.9±0.614. (P value <0.001). Conclusion: We conclude that preemptive use of gabapentin 600mg and pregabalin 150 mg orally significantly reduces the postoperative rescue analgesic requirement and increases the duration of postoperative analgesia in patients undergoing

    We describe an unusual case of osteosarcoma in a Jehovah's Witness patient who underwent chemotherapy and major surgery without the need for blood transfusion. This 16-year-old girl presented with osteosarcoma of the right proximal tibia requiring proximal tibia resection, followed by endoprosthesis replacement. She was successfully treated with neoadjuvant chemotherapy and surgery with the support of haematinics, granulocyte colony-stimulating factor, recombinant erythropoietin and intraoperative normovolaemic haemodilution. This case illustrates the importance of maintaining effective, open communication and exploring acceptable therapeutic alternative in the management of these patients, whilst still respecting their beliefs.

    Full Text Available Spinal schwannomas are benign tumors arising from spinal nerve root sheaths. It is a primary spinal tumor which are rare in children. We report a case of a 12 year old girl who presented with weakness of all limbs and unable to walk. Imaging studies demonstrated an extradural spinal tumor at cervical spine. The patient was operated and tumor was totally removed. The postoperative course was uneventful. Histology confirmed the diagnosis of schwannoma. After surgery there was improvement in signs and symptoms. After two months of operation, child could able to walk normally.

    Full Text Available OBJECTIVES: Patients with Type I neurofibromatosis scoliosis with intra-canal rib head protrusion are extremely rare. Current knowledge regarding the diagnosis and treatment for this situation are insufficient. The purpose of this study is to share our experience in the diagnosis and surgical treatments for such unique deformities. METHODS: Six patients with Type I neurofibromatosis scoliosis with rib head dislocation into the spinal canal were diagnosed at our institution. Posterior instrumentation and spinal fusion without intra-canal rib head resection via a posterior-only approach was performed for deformity correction and rib head extraction. The efficacy and outcomes of the surgery were evaluated by measurements before, immediately and 24 months after the surgery using the following parameters: coronal spinal Cobb angle, apex rotation and kyphosis of the spine and the intra-canal rib head position. Post-operative complications, surgery time and blood loss were also evaluated. RESULTS: Patients were followed up for at least 24 months post-operatively. The three dimensional spinal deformity was significantly improved and the intra-canal rib head was significantly extracted from the canal immediately after the surgery. At follow-up 24 months after surgery, solid fusions were achieved along the fusion segments, and the deformity corrections and rib head positions were well maintained. There were no surgery-related complications any time after the surgery. CONCLUSIONS: Systematic examinations are needed to identify patients with Type I neurofibromatosis scoliosis with rib head dislocation into the canal who can be treated by posterior-only spinal fusion without rib head resection.

    The authors describe a new procedure to detect the tiny dural hole in patients with superficial siderosis (SS) and CSF leakage using a coronary angioscope system for spinal endoscopy and selective CT myelography using a spinal drainage tube. Under fluoroscopy, surgeons inserted the coronary angioscope into the spinal subarachnoid space, similar to the procedure of spinal drainage, and slowly advanced it to the cervical spine. The angioscope clearly showed the small dural hole and injured arachnoid membrane. One week later, the spinal drainage tube was inserted, and the tip of the drainage tube was located just below the level of the dural defect found by the spinal endoscopic examination. This selective CT myelography clarifies the location of the dural defect. During surgery, the small dural hole could be easily located, and it was securely sutured. It is sometimes difficult to detect the actual location of the small dural hole even with thin-slice MRI or dynamic CT myelography in patients with SS. The use of a coronary angioscope for the spinal endoscopy combined with selective CT myelography may provide an effective examination to assess dural closure of the spinal dural defect with SS in cases without obvious dural defects on conventional imaging.

    Approximately 20% of children develop persistent pain after major surgery. Sleep disruption has been implicated as a predictor of children's acute postsurgical pain. However, perioperative sleep patterns have not been longitudinally assessed, and the role of sleep in persistence of postsurgical pain has not been explored. We aimed to examine sleep patterns over 4 months in children having major surgery, and temporal relationships between daily sleep and pain. Sixty children age 10 to 18 (mean = 14.7) years having major surgery completed 7 days of actigraphy sleep monitoring (sleep duration, efficiency), twice daily electronic diaries (sleep quality, pain intensity, medication use), and validated questionnaires at presurgery, 2 weeks, and 4 months postsurgery. Generalized linear models, controlling for age, sex, naps, and medication, showed sleep quality (β [B] = -.88, P sleep quality was significantly associated with greater next day pain intensity (B = -.15, P = .005). Sleep duration and efficiency were not associated with subsequent pain; daytime pain was not associated with subsequent sleep. Findings suggest sleep quality may be an important target for intervention after surgery in children; research is needed to understand how other sleep parameters may relate to recovery. This study assessed longitudinal sleep patterns over 4 months after major pediatric surgery using actigraphy, diaries, and validated measures. Sleep quality and efficiency were significantly reduced at 2 weeks. Poorer sleep quality was associated with greater next day pain intensity suggesting that sleep quality may be an important target for intervention. Copyright © 2017 American Pain Society.

    In the last years, there has been a change in the aetiology of spinal cord injury. There has been an increase in the number of elderly patients with spinal cord injuries caused by diseases or medical procedures. The aim of this study is to investigate the frequency of the occurrence of iatrogenic spinal cord injury in our unit. The secondary aim is to study what variables can be associated with a higher risk of iatrogenesis. A retrospective, descriptive, observational study of patients with acute spinal cord injury admitted from June 2009 to May 2014 was conducted. The information collected included the patient age, aetiology, neurological level and grade of injury when admitted and when discharged, cardiovascular risk factors, a previous history of depression and any prior treatment with anticoagulant or antiplatelet drugs. We applied a logistic regression. The grade of statistical significance was established as Pinjury was the thoracic level (48%). The main aetiology of spinal cord injury caused by iatrogenesis was surgery for degenerative spine disease, in patients under the age of 30 were treated with intrathecal chemotherapy. Iatrogenic spinal cord injury is a frequent complication. A statistically significant association between a patient history of depression and iatrogenic spinal cord injury was found as well as with anticoagulant and antiplatelet drug use prior to iatrogenic spinal cord injury.

    Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml?1 mixed with 0.5 ml of fentanyl 50 ?g ml?1.

  5. Continuous spinal anesthesia.

    Moore, James M

    2009-01-01

    Continuous spinal anesthesia (CSA) is an underutilized technique in modern anesthesia practice. Compared with other techniques of neuraxial anesthesia, CSA allows incremental dosing of an intrathecal local anesthetic for an indefinite duration, whereas traditional single-shot spinal anesthesia usually involves larger doses, a finite, unpredictable duration, and greater potential for detrimental hemodynamic effects including hypotension, and epidural anesthesia via a catheter may produce lesser motor block and suboptimal anesthesia in sacral nerve root distributions. This review compares CSA with other anesthetic techniques and also describes the history of CSA, its clinical applications, concerns regarding neurotoxicity, and other pharmacologic implications of its use. CSA has seen a waxing and waning of its popularity in clinical practice since its initial description in 1907. After case reports of cauda equina syndrome were reported with the use of spinal microcatheters for CSA, these microcatheters were withdrawn from clinical practice in the United States but continued to be used in Europe with no further neurologic sequelae. Because only large-bore catheters may be used in the United States, CSA is usually reserved for elderly patients out of concern for the risk of postdural puncture headache in younger patients. However, even in younger patients, sometimes the unique clinical benefits and hemodynamic stability involved in CSA outweigh concerns regarding postdural puncture headache. Clinical scenarios in which CSA may be of particular benefit include patients with severe aortic stenosis undergoing lower extremity surgery and obstetric patients with complex heart disease. CSA is an underutilized technique in modern anesthesia practice. Perhaps more accurately termed fractional spinal anesthesia, CSA involves intermittent dosing of local anesthetic solution via an intrathecal catheter. Where traditional spinal anesthesia involves a single injection with a

    Treatment of elderly cancer patients has gained importance. One question regarding the treatment of metastatic spinal cord compression (MSCC) is whether elderly patients benefit from surgery in addition to radiotherapy? In attempting to answer this question, we performed a matched-pair analysis comparing surgery followed by radiotherapy to radiotherapy alone. Data from 42 elderly (age > 65 years) patients receiving surgery plus radiotherapy (S + RT) were matched to 84 patients (1:2) receiving radiotherapy alone (RT). Groups were matched for ten potential prognostic factors and compared regarding motor function, local control, and survival. Additional matched-pair analyses were performed for the subgroups of patients receiving direct decompressive surgery plus stabilization of involved vertebrae (DDSS, n = 81) and receiving laminectomy (LE, n = 45). Improvement of motor function occurred in 21% after S + RT and 24% after RT (p = 0.39). The 1-year local control rates were 81% and 91% (p = 0.44), while the 1-year survival rates were 46% and 39% (p = 0.71). In the matched-pair analysis of patients receiving DDSS, improvement of motor function occurred in 22% after DDSS + RT and 24% after RT alone (p = 0.92). The 1-year local control rates were 95% and 89% (p = 0.62), and the 1-year survival rates were 54% and 43% (p = 0.30). In the matched-pair analysis of patients receiving LE, improvement of motor function occurred in 20% after LE + RT and 23% after RT alone (p = 0.06). The 1-year local control rates were 50% and 92% (p = 0.33). The 1-year survival rates were 32% and 32% (p = 0.55). Elderly patients with MSCC did not benefit from surgery in addition to radiotherapy regarding functional outcome, local control of MSCC, or survival. (orig.)

    , thereby improving or normalizing flexion-relaxation and increasing lumbar flexion ROM. At 1 year after discharge from the program, a structured interview was used to obtain socioeconomic outcomes. At pre-rehabilitation, the no surgery group patients demonstrated significantly better performance than both surgery groups on absolute SEMG at maximum voluntary flexion and on true lumbar flexion ROM. Both surgery groups were less likely to achieve flexion-relaxation than the no surgery patients. The fusion patients had reduced gross lumbar flexion ROM and greater pain during bending compared with the no surgery patients, and reduced true lumbar flexion ROM compared with the discectomy patients. At post-rehabilitation, all groups improved substantially on all measures. When post-rehabilitation measures were compared with the pain-free control group, with gross and true lumbar ROM corrected by 8° per spinal segment fused, there were no differences between any of the patient groups and the pain-free control subjects on spinal ROM and only small differences in SEMG. The three groups had comparable socioeconomic outcomes at 1 year post-treatment in work retention, health-care utilization, new injury, and new surgery. Despite the fact that the patients with prior surgery demonstrated greater pretreatment SEMG and ROM deficits, functional restoration treatment, combined with SEMG-assisted stretching training, was successful in improving all these measures by post-treatment. After treatment, both groups demonstrated ROM within anticipated limits, and the majority of patients in all three groups successfully achieved flexion-relaxation. In a chronic disabling occupational lumbar spinal disorder cohort, surgery patients were nearly equal to nonoperated patients in responding to interdisciplinary functional restoration rehabilitation on measures investigated in this study, achieving close to normal performance measures associated with pain-free controls. The responsiveness and final

    2018-05-01

    As a tertiary referral centre of spinal surgery, the Royal National Orthopaedic Hospital (RNOH) handles hundreds of spinal cases a year, often with complex pathology and complex care needs. Despite this, issues were raised at the RNOH following lack of sufficient documentation of preoperative and postoperative clinical findings in spinal patients undergoing major surgery. This is not in keeping with guidelines provided by the Royal College of Surgeons. The authors believe that a standardised clerking pro forma for surgical spinal patients admitted to RNOH would improve the quality of care provided. Therefore, the use of a standard clerking pro forma for all surgical spinal patients could be a useful tool enabling improvements in patients care and safety in keeping with General Medical Council/National Institute for Health and Care Excellence guidelines. An audit (with closure of loop) looking into the quality of the preoperative and postoperative clinical documentation for surgical spinal patients was carried out at the RNOH in 2016 (retrospective case note audit comparing preintervention and postintervention documentation standards). Our standardised pro forma allows clinicians to best utilise their time and standardises examination to be compared in a temporal manner during the patients admission and care. It is the authors understanding that this work is a unique study looking at the quality of the admission clerking for surgical spinal patients. Evidently, there remains work to be done for the widespread utilisation of the pro forma. Early results suggest that such a pro forma can significantly improve the documentation in admission clerking with improvements in the quality of care for patients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    2006-05-01

    Full Text Available Background:Postoperative pain is an important surgical problem. Recent studies in pain pathophysiology have led to the hypothesis that with perioperative administration of analgesics (pre-emptive analgesia it may be possible to prevent or reduce postoperative pain. This study was planned to investigate the efficacy of pre-emptive analgesia on postoperative pain after major gynecologic abdominal surgeries. Methods: In this prospective, double-blinded, randomized, and placebocontrolled trial, 60 ASA physical status I and II patients undergoing major abdominal gynecologic surgeries were randomized to receive 45 mL of bupivacaine 0.375% or 45mL of normal saline; 30 mL and 15 mL of the treatment solution was administered into the peritoneal cavity and incision, respectively, before wound closure. The pain score of the patients was evaluated by the visual analogue scale (VAS on awakening, and at 6, 12, and 24h after surgery. Time to first analgesia request and total analgesic requirements in the first 24h were recorded. Results: Pain scores were significantly higher in the placebo group than in the bupivacaine group on awakening (5.98±1.01 v.s 1.05±1.05; p<0.001, and at 6h after surgery (5.37±0.85 vs. 2.51±1.02; p<0.001. First request to analgesia was significantly longer in the bupivacaine patients than in the placebo group (5.87±3.04 h vs.1.35±0.36; p<0.001.Meperidine consumption over 24h was 96.00 ±17.53 mg in the placebo group compared with 23.28 ±14.89 mg in the bupivacaine patients (p<0.001.Conclusion:A combination of intraperitoneal and incisional bupivacaine infiltration at the end of abdominal gynecologic surgeries reduces postoperative pain on awakening and for 6 hours after surgery, and provides significant opioidsparing analgesia for 24 h after gynecologic abdominal surgeries.

    The purpose of this study was to examine mental health treatment use among Vietnam Veterans with posttraumatic stress disorder and determine whether undergoing major surgery interrupted mental health treatment or increased the risk of psychiatric hospitalization. Using retrospective data from Veterans Health Administration's electronic medical record system, a total of 3320 Vietnam-era surgery patients with preoperative posttraumatic stress disorder were identified and matched 1:4 with non-surgical patients with posttraumatic stress disorder. The receipt of surgery was associated with a decline in overall mental health treatment and posttraumatic stress disorder-specific treatment 1 month following surgery but not during any subsequent month thereafter. Additionally, surgery was not associated with psychiatric admission. © The Author(s) 2014.

    The aim of this study was to investigate whether an increased frequency of gastro-oesophageal reflux (GOR) is more common in large-sized, deep-chested dogs undergoing spinal surgery in sternal recumbency than in small-sized, barrelchested dogs. Prospective, cohort study. Nineteen small-sized, barrel-chested dogs (group B) and 26 large-sized, deep-chested dogs (group D). All animals were premedicated with intramuscular (IM) acepromazine (0.05 mg kg -1 ) and pethidine (3 mg kg -1 ) IM. Anaesthesia was induced with intravenous sodium thiopental and maintained with halothane in oxygen. Lower oesophageal pH was monitored continuously after induction of anaesthesia. Gastro-oesophageal reflux was considered to have occurred whenever pH values > 7.5 or < 4 were recorded. If GOR was detected during anaesthesia, measures were taken to avoid aspiration of gastric contents into the lungs and to prevent the development of oesophagitis/oesophageal stricture. The frequency of GOR during anaesthesia was significantly higher in group D (6/26 dogs; 23.07%) than in group B (0/19 dogs; 0%) (p = 0.032). Signs indicative of aspiration pneumonia, oesophagitis or oesophageal stricture were not reported in any of the GOR cases. In large-sized, deep-chested dogs undergoing spinal surgery in sternal recumbency, it would seem prudent to consider measures aimed at preventing GOR and its potentially devastating consequences (oesophagitis/oesophageal stricture, aspiration pneumonia).

    We receive a large number of patients with spinal cord injury (SCI) due to penetrating gunshot wounds (GSW) at our national rehabilitation center. Although many patients are labeled American Spinal Injury Association (ASIA) B sensory incomplete because of sensory sparing, especially deep anal pressure, with purported prognostic value, we have not observed a clinical difference from patients labeled ASIA A complete. We hypothesized that sensory sparing, if meaningful, should reduce the occurrence of pressure ulcers. To determine if ASIA classifications A and B are important distinctions for patients with SCIs secondary to civilian gunshot wounds. A retrospective chart review was performed on all patients with civilian gunshot-induced SCI transferred to Rancho Los Amigos Rehabilitation Center between 1999 and 2014. Outcome measures were occurrence of pressure ulcers and surgical intervention for pressure ulcers. We included a total of 487 patients who sustained civilian gunshot wounds to the spine and were provided care at Rancho Los Amigos Rehabilitation Center from 2001 to 2014. Occurrence of pressure ulcers and surgical intervention for pressure ulcers among patients who suffered civilian-induced gunshot wounds to the spine. Retrospective chart review identified 487 SCIs due to gunshot wounds that were treated at Rancho Los Amigos from 2001 to 2014. Injury characteristics including ASIA classification, pressure ulcers, and pressure ulcer surgeries were recorded. Comprehensive surgical data were obtained for all patients. Chart reviews and telephone interviews were performed to determine the occurrence of any pressure ulcers and pressure ulcer surgeries. Statistical analysis was performed to compare data by spinal region and ASIA grade. There were no conflicts of interest from any of the authors, and there was no funding obtained for this study. There was no statistical difference for cervical ASIA A versus ASIA B for the occurrence of pressure ulcers or the

    Patients with pre-existing cervical spinal canal stenosis (CSCS) may have minimal or no symptoms. However, performing preventive decompression is controversial as the incidence of CSCS leading to severe cord injury is unknown. Hence, this study aims to revisit the threshold for surgery in "silent" CSCS by reviewing the neurologic outcomes of patients with undiagnosed CSCS who sustained a cervical spinal cord injury (CSCI). Two groups of subjects were recruited for analysis. Firstly, patients with trauma-induced CSCI without fracture or dislocation were included. Pre-existing CSCS was diagnosed by MRI measurements. The second group consisted of asymptomatic subjects recruited from the general population who also had MRIs performed. Canal sizes were compared between this control group and the patient group. Within the patient group, neurological assessments and outcomes by Frankel classification were performed in patients treated surgically or conservatively. 32 patients with CSCS were recruited. The mean spinal canal sagittal diameter (disc-level) of all CSCS cases was 5.3 ± 1.4 mm (1.3-8.2). In comparison, the diameter was 10.5 ± 1.7 mm (6.6-14.6) in the 47 asymptomatic individuals recruited from the general population. Decompression was performed in 17 patients and conservative treatment in 15. Mean follow-up was 19.3 ± 17.0 months (6-84). At the final follow-up, 3 patients (9.3%) returned to their pre-injury Frankel grade, whereas 26 patients (83.3%) lost one or more neurological grade. Three patients (9.3%) died. Majority of patients with "silent" CSCS who sustained cervical cord injuries did not return to their pre-injury neurological status. All of these subjects have pre-existing canal stenosis hence the risk of cord injury. Given the poor neurological outcome of CSCS, a lower threshold for surgery could be indicated to avoid these disastrous injuries. However, before making any conclusive recommendation we must first identify the prevalence of

    The vascular supply of the thoracic spinal cord depends on the thoracolumbar segmental arteries. Because of the small size and ventral course of these arteries in relation to the dorsal root ganglion and ventral root, they cannot be reliably identified during surgery by anatomic or morphologic criteria. Sacrificing them will most likely result in paraplegia. The goal of this study was to evaluate a novel method of intraoperative testing of a nerve root's contribution to the blood supply of the thoracic spinal cord. This is a clinical retrospective study of 49 patients diagnosed with thoracic spine tumors. Temporary nerve root clipping combined with motor-evoked potential (MEP) and somatosensory-evoked potential (SSEP) monitoring was performed; additionally, postoperative clinical evaluation was done and reported in all cases. All cases were monitored by SSEP and MEPs. The nerve root to be sacrificed was temporarily clipped using standard aneurysm clips, and SSEP/MEP were assessed before and after clipping. Four nerve roots were sacrificed in four cases, three nerve roots in eight cases, and two nerve roots in 22 cases. Nerve roots were sacrificed bilaterally in 12 cases. Most patients (47/49) had no changes in MEP/SSEP and had no neurological deficit postoperatively. One case of a spinal sarcoma demonstrated changes in MEP after temporary clipping of the left T11 nerve root. The nerve was not sacrificed, and the patient was neurologically intact after surgery. In another case of a sarcoma, MEPs changed in the lower limbs after ligation of left T9 nerve root. It was felt that it was a global event because of anesthesia. Postoperatively, the patient had complete paraplegia but recovered almost completely after 6 months. Temporary nerve root clipping combined with MEP and SSEP monitoring may enhance the impact of neuromonitoring in the intraoperative management of patients with thoracic spine tumors and favorably influence neurological outcome.

    Major complications following aesthetic breast surgery are uncommon and thus assessment of risk factors is challenging. To determine the incidence and risk factors of major complications following aesthetic breast surgery and concomitant procedures. A prospective cohort of patients who enrolled into the CosmetAssure (Birmingham, AL) insurance program and underwent aesthetic breast surgery between 2008 and 2013 was identified. Major complications (requiring reoperation, readmission, or emergency room visit) within 30 days of surgery were recorded. Risk factors including age, smoking, body mass index (BMI), diabetes, type of surgical facility, and combined procedures were evaluated. Among women, augmentation was the most common breast procedure (n = 41,651, 58.6%) followed by augmentation-mastopexy, mastopexy, and reduction. Overall, major complications occurred in 1.46% with hematoma (0.99%) and infection (0.25%) being most common. Augmentation-mastopexy had a higher risk of complications, particularly infection (relative risk [RR] 1.74, P procedures. Age was the only significant predictor for hematomas (RR 1.01, P procedures or abdominoplasty performed alone. Among men, correction of gynecomastia was the most common breast procedure (n = 1613, 64.6%) with a complication rate of 1.80% and smoking as a risk factor (RR 2.73, P = 0.03). Incidence of major complications after breast cosmetic surgical procedures is low. Risk factors for major complications include increasing age and BMI. Combining abdominoplasty with any breast procedure increases the risk of major complications. 2. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    Delayed paraplegia due to spinal cord ischemia/reperfusion injury (IRI) remains one of the most severe complications of thoracoabdominal aneurysm surgery, for which effective prevention and treatment is still lacking. The current study investigates whether spinal cord stimulation (SCS) postconditioning has neuroprotective effects against spinal cord IRI. Ninety-six New Zealand white male rabbits were randomly divided into four groups as follows: a sham group and three experimental groups (C group, 2 Hz group, and 50 Hz group) n = 24/group. Spinal cord ischemia was induced by transient infrarenal aortic balloon occlusion for 28 min, after which rabbits in group C underwent no additional intervention, while rabbits in the other two experimental groups underwent 2 Hz or 50 Hz epidural SCS for 30 min at the onset of reperfusion and then daily until sacrifice. Hind limb neurologic function of rabbits was assessed using Jacob scale. Lumbar spinal cords were harvested immediately after sacrifice for histological examination and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. The number of viable α-motor neurons in ventral horn was counted and TUNEL-positive rate of α-motor neurons was calculated. Spinal cord IRI was caused by transient infrarenal aorta occlusion for 28 min. Both 2 Hz and 50 Hz SCS postconditioning had neuroprotective effects, particularly the 2 Hz SCS postconditioning. Comparing to C group and 50 Hz group, rabbits in the 2 Hz group demonstrated better hind limb motor function and a lower rate of TUNEL-positive α-motor neuron after eight hours, one day, three days, and seven days of spinal cord reperfusion. More viable α-motor neurons were preserved after one and three days of spinal cord reperfusion in 2 Hz group rabbits than in C group and 50 Hz group rabbits. SCS postconditioning at 2 Hz protected the spinal cord from IRI. © 2018 International Neuromodulation Society.

    An 11-year-old spayed female Siberian Husky was evaluated because of a 2-week history of progressive paraparesis. Results of neurologic examination were consistent with a T3-L3 myelopathy. There were no abnormalities on CBC, and hypercalcemia was noted on serum biochemical analysis. Several hypoechoic splenic nodules were evident on abdominal ultrasonography, and results of fine-needle aspiration cytology were consistent with splenic extramedullary hematopoiesis (EMH). Two compressive, extradural masses in the dorsal epidural space of the thoracolumbar region of the spinal cord were seen on MRI images. A dorsal laminectomy was performed to remove the extradural spinal masses. Results of histologic examination of tissue samples were consistent with EMH. Following surgery, clinical signs of paraparesis resolved, and there was no recurrence of the masses 24 months after surgery. Extramedullary hematopoesis should be considered as a differential diagnosis in dogs in which results of diagnostic imaging indicate a epidural mass. In human patients, spinal EMH usually occurs secondary to an underlying hematologic disease, but it can also occur spontaneously. Treatment options reported for humans include surgical decompression, radiation therapy, chemotherapy, and blood transfusion. The dog of this report responded favorably to surgical decompression and was clinically normal 2 years after surgery.

    Subarachnoid hemorrhage (SAH) of spinal origin is uncommon in clinical practice, and spinal schwannomas associated with SAH are even more rarely reported. We report an unusual case of spinal SAH mimicking meningitis with normal brain computed tomography (CT)/magnetic resonance imaging (MRI) and negative CT angiography. Cerebrospinal fluid examination results were consistent with the manifestation of SAH. Spinal MRI performed subsequently showed an intradural extramedullary mass. The patient received surgery and was finally diagnosed with spinal cord schwannoma. A retrospective chart review of the patient was performed. We describe a case of SAH due to spinal cord schwannoma. Our case highlights the importance of careful history taking and complete evaluation. We emphasize that spinal causes should always be ruled out in patients with angionegative SAH and that schwannoma should be considered in the differential diagnosis of SAH etiologies even though rare.

    Full Text Available Background: Motor vehicle crashes and falls account for most of the spine fractures with subsequent serious disability. Aim: To define the incidence, causes, and outcome of spinal fractures. Materials and Methods: Data were collected retrospectively from trauma registry database of all traumatic spinal injuries admitted to the section of trauma surgery in Qatar from November 2007 to December 2009. Results: Among 3712 patients who were admitted to the section of trauma surgery, 442 (12% injured patients had spinal fractures with a mean age of 33.2 ± 12 years. The male to female ratio was 11.6:1. Motor vehicle crashes (36.5% and falls from height (19.3% were the leading causes of cervical injury (P = 0.001. The injury severity score ranged between 4 and 75. Nineteen percent of cases with cervical injury had thoracic injury as well (P = 0.04. Lumber injury was associated with thoracic injury in 27% of cases (P < 0.001. Combined thoracic and lumber injuries were associated with cervical injury in 33% of cases (P < 0.001. The total percent of injuries associated with neurological deficit was 5.4%. Fifty-three cases were managed surgically for spine fractures; 14 of them had associated neurological deficits. Overall mortalityrate was 5%. Conclusions: Spine fractures are not uncommon in Qatar. Cervical and thoracic spine injuries carry the highest incidence of associated neurological deficit and injuries at other spinal levels. Young males are the most exposed population that deserves more emphasis on injury prevention programs in the working sites and in enforcement of traffic laws.

    The object of this study was to investigate correlations between sagittal spinopelvic alignment and improvements in clinical and quality-of-life (QOL) outcomes after lumbar decompression surgery for lumbar spinal canal stenosis (LCS) without coronal imbalance. The authors retrospectively reviewed data from consecutive patients treated for LCS with decompression surgery in the period from 2009 through 2011. They examined correlations between preoperative or postoperative sagittal vertical axis (SVA) and radiological parameters, clinical outcomes, and health-related (HR)QOL scores in patients divided according to SVA. Clinical outcomes were assessed according to Japanese Orthopaedic Association (JOA) and visual analog scale (VAS) scores. Health-related QOL was evaluated using the Roland-Morris Disability Questionnaire (RMDQ) and the JOA Back Pain Evaluation Questionnaire (JOABPEQ). One hundred nine patients were eligible for inclusion in the study. Compared to patients with normal sagittal alignment prior to surgery (Group A: SVA imbalance (Group B: SVA ≥ 50 mm) had significantly smaller lumbar lordosis and thoracic kyphosis angles and larger pelvic tilt. In Group B, there was a significant decrease in postoperative SVA compared with the preoperative SVA (76.3 ± 29.7 mm vs. 54.3 ± 39.8 mm, p = 0.004). The patients in Group B with severe preoperative sagittal imbalance (SVA > 80 mm) had residual sagittal imbalance after surgery (82.8 ± 41.6 mm). There were no significant differences in clinical and HRQOL outcomes between Groups A and B. Compared to patients with normal postoperative SVA (Group C: SVA imbalance. Decompression surgery improved the SVA value in patients with preoperative sagittal imbalance; however, the patients with severe preoperative sagittal imbalance (SVA > 80 mm) had residual imbalance after decompression surgery. Both clinical and HRQOL outcomes were negatively affected by postoperative residual sagittal imbalance.

  6. Analysis of Patients with Myelopathy due to Benign Intradural Spinal Tumors with Concomitant Lumbar Degenerative Diseases Misdiagnosed and Erroneously Treated with Lumbar Surgery.

    When a cervical or thoracic benign intradural spinal tumor (BIST) coexists with lumbar degenerative diseases (LDD), diagnosis can be difficult. Symptoms of BIST-myelopathy can be mistaken as being related to LDD. Worse, an unnecessary lumbar surgery could be performed. This study was conducted to analyze cases in which an erroneous lumbar surgery was undertaken in the wake of failure to identify BIST-associated myelopathy. Cases were found in a hospital database. Patients who underwent surgery for LDD first and then another surgery for BIST removal within a short interval were studied. Issues investigated included why the BISTs were missed, how they were found later, and how the patients reacted to the unnecessary lumbar procedures. Over 10 years, 167 patients received both surgeries for LDD and a cervical or thoracic BIST. In 7 patients, lumbar surgery preceded tumor removal by a short interval. Mistakes shared by the physicians included failure to detect myelopathy and a BIST, and a hasty decision for lumbar surgery, which soon turned out to be futile. Although the BISTs were subsequently found and removed, 5 patients believed that the lumbar surgery was unnecessary, with 4 patients expressing regrets and 1 patient threatening to take legal action against the initial surgeon. Concomitant symptomatic LDD and BIST-associated myelopathy pose a diagnostic challenge. Spine specialists should refrain from reflexively linking leg symptoms and impaired ability to walk to LDD. Comprehensive patient evaluation is fundamental to avoid misdiagnosis and wrong lumbar surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

  7. Symptomatic spinal cord deformity secondary to a redundant intramedullary shunt catheter

    Right arm pain, motor and sensory loss in the right arm and right facial numbness recurred in a 27 year old quadraplegic shortly after a posttraumatic spinal cord cyst (PTSCC) was shunted via a catheter into the adjacent subarachnoid space. Although shunt malfunction was clinically suspected, metrizamide computed tomography (MCT) suggested that redundancy of the catheter had caused deformity of the spinal cord. This hypothesis was confirmed at surgery when intraoperative spinal sonography (IOSS) showed that the spinal cord deformity at C 1 -C 2 disappeared when the catheter was withdrawn. This case shows that new or recurrent spinal cord symptoms may be due to a mechanical deformity of the cord rather than shunt malfunction, that restricting the length of the shunt catheter which is used to decompress PTSCCs is important, and that IOSS is an indispensible tool for visualizing the changes in spinal cord morphology during shunting procedures.

  9. Lumbar Spinal Stenosis: Who Should Be Fused? An Updated Review

    Science.gov (United States)

    Hasankhani, Ebrahim Ghayem; Ashjazadeh, Amir

    2014-01-01

    Lumbar spinal stenosis (LSS) is mostly caused by osteoarthritis (spondylosis). Clinically, the symptoms of patients with LSS can be categorized into two groups; regional (low back pain, stiffness, and so on) or radicular (spinal stenosis mainly presenting as neurogenic claudication). Both of these symptoms usually improve with appropriate conservative treatment, but in refractory cases, surgical intervention is occasionally indicated. In the patients who primarily complain of radiculopathy with an underlying biomechanically stable spine, a decompression surgery alone using a less invasive technique may be sufficient. Preoperatively, with the presence of indicators such as failed back surgery syndrome (revision surgery), degenerative instability, considerable essential deformity, symptomatic spondylolysis, refractory degenerative disc disease, and adjacent segment disease, lumbar fusion is probably recommended. Intraoperatively, in cases with extensive decompression associated with a wide disc space or insufficient bone stock, fusion is preferred. Instrumentation improves the fusion rate, but it is not necessarily associated with improved recovery rate and better functional outcome. PMID:25187873

    2008-05-01

    A 46-year-old man, with a history of atopic dermatitis and bronchial asthma, underwent surgery for an inguinal hernia. Forty-three minutes subsequent to spinal anesthesia, the patient complained suddenly of dyspnea with wheezing. Blood pressure decreased and skin eruption was observed on his chest. Postoperative laboratory tests revealed high IgE concentration, and a skin test confirmed an allergy to latex. The patient's allergic reaction was easily overlooked because of his history of bronchial asthma and the possibility that the hypotension was caused by the high spinal anesthesia. Latex allergy should be considered in any suspicious case presenting with these symptoms during surgery. After recovery, a skin test should be used to confirm the allergy to avoid repeated allergic episodes.

  11. Hypobaric spinal anesthesia in the operative management of orthopedic emergencies in geriatric patients.

    Sidi, A; Pollak, D; Floman, Y; Davidson, J T

    1984-07-01

    Hypobaric spinal anesthesia was administered to 40 patients undergoing lower limb surgery. Twenty-nine of the patients were debilitated geriatric patients who presented with orthopedic emergencies, in most cases a fractured hip. Hypobaric spinal anesthesia was found to be a simple and safe procedure that provided adequate analgesia. Due to its inherent nature, hypobaric spinal anesthesia does not necessitate positioning of the patient on the injured, painful side (unlike hyperbaric spinal or epidural anesthesia) and, therefore, facilitates a smooth and painless transfer of the patient to the operating table. Complications encountered were similar to those following hyperbaric anesthesia.

    1995-01-01

    Purpose: In assessing effectiveness of radiation therapy (RT) in metastatic spinal cord compression (MSCC), we performed a prospective trial in which patients with this complication were generally treated with RT plus steroids, and surgery was reserved for selected cases. Methods and Materials: Two hundred seventy-five consecutive patients with MSCC entered this protocol. Twenty (7%) underwent surgery plus RT, another 255 received RT alone. Of all eligible patients, 25 (10%) early deaths and 21 (8%) entering a feasibility study of RT without steroids, were not evaluable. Of the 209 evaluable cases, 110 were females and 99 males, and median age was 62 years. Median follow-up was 49 months (range, 13 to 88) and treatment consisted of 30 Gy RT (using two different schedules) together with steroids (standard or high doses, depending on motor deficit severity). Response was assessed according to back pain and motor and bladder function before and after therapy. Results: Back pain total response rate was 82% (complete or partial response or stable pain, 54, 17, or 11%, respectively). About three-fourths of the patients (76%) achieved full recovery or preservation of walking ability and 44% with sphincter dysfunction improved. Early diagnosis was the most important response predictor so that a large majority of patients able to walk and with good bladder function maintained these capacities. When diagnosis was late, tumors with favorable histologies (i.e., myeloma, breast, and prostate carcinomas) above all responded to RT. Duration of response was also influenced by histology. Favorable histologies are associated to higher median response (myeloma, breast, and prostate carcinomas, 16, 12, and 10 months, respectively). Median survival time was 6 months, with a 28% probability of survival for 1 year. Survival time was longer for patients able to walk before and/or after RT, those with favourable histologies, and females. There was agreement between patient survival and

    Full Text Available Spine is the primary bone site affected by systemic metastasis. Although there are scales that attempt to manage these patients, their real applicability is unknown. The Tokuhashi Scoring System (TSS is a widely used prognostic tool. At the time of treatment, the data necessary to complete TSS may be incomplete, making its application impossible. Objective To evaluate the number of TSS scores completed by the time the clinical therapeutic decision was made. Methods From July 2010 to January 2012, we selected patients who were diagnosed with spinal metastases. Results Sixty spinal metastasis patients (21 female, 39 male were evaluated between July 2010 and January 2012. At the time of the treatment decision, only 25% of the patients had completed the TSS items. Conclusion In the majority of patients with vertebral metastasis, TSS variables cannot be applied.

    Case report. To describe an iatrogenic aortic injury by pedicle screw instrumentation during posterior reconstructive surgery of spinal deformity. Iatrogenic major vascular injuries during anterior instrumentation procedures have been reported by several authors, but there have been few reports regarding iatrogenic major vascular injuries during posterior instrumentation procedures. A 57-year-old woman with thoracolumbar kyphosis due to osteoporotic T12 vertebral fracture underwent posterior correction and fusion (T10-L2), using segmental pedicle screw construct concomitant with T12 pedicle subtraction osteotomy. Postoperative routine plain radiographs and computed tomography myelography demonstrated a misplaced left T10 pedicle screw, which was in contact with the posteromedial aspect of the thoracic aorta, and suspected penetration of the aortic wall. The patient underwent removal of the pedicle screw, and repair of the penetrated aortic wall through a simultaneous anterior-posterior approach. The patient tolerated the procedure well without neurologic sequelae, and was discharged several days after removal of a left tube thoracostomy. Plain radiographs demonstrated solid fusion at the osteotomy site and no loosening of hardware. Preoperative neurologic symptoms improved completely at 18-months follow-up. Use of pedicle screw instrumentation has the potential to cause major vascular injury during posterior spinal surgery, and measures to prevent this complication must be taken. Timely diagnosis and treatment are essential to prevent both early and delayed complications and death.

    2000-01-01

    Objective: To analyze the technique and to evaluate the safety and value of preoperative trans-arterial embolization of hypervascular spinal tumors. Methods: Eighteen patients with hypervascular spinal tumors underwent trans-arterial embolization before surgery. They arose intradural in six patients and extradural in 12. Thirty-one arteries were embolized with polyvinyl alcohol (PVA) particles (150-500 μm), of which 18 with additional pieces of gelatin sponge for proximal pedicular embolization. The criteria for judging the effectiveness of embolization were the completeness of tumor removal and estimated blood loss during surgery. Results: Tumor embolization with total occlusion was obtained in eight patients, second to total in seven, subtotal in one, and partial in two. There were no symptomatic complications associated with embolization. Tumors were totally removed in 17 patients and nearly totally removed in one. The average estimated blood loss during surgery was 1100 ml (range, 200-6000 ml) for all 18 patients, and 1540 ml in patients with extradural tumors. Conclusions: Preoperative embolization of hypervascular spinal tumors is safe and effective. It can make complete resection of a tumor possible and can make an unresectable tumor resectable. Superselection or flow control is necessary to achieve effective devascularization and avoid complications

    Sandrasegaran, Kumaresan; Maglinte, Dean D.T.

    2005-01-01

    To recognize and document the small bowel reactions following major abdominal surgery is an important key for a correct diagnosis. Usually, plain abdominal radiography is the initial imaging examination requested in the immediate postoperative period, whereas gastrointestinal contrast studies are used to look for specific complications. In some countries, especially in Europe, sonography is widely employed to evaluate any acute affection of the abdomen. CT is commonly used to assess postoperative abdominal complications; in our institution also CT enteroclysis is often performed, to provide additional important informations. Radiologist should be able to diagnose less common types of obstruction, such as afferent loop, closed loop, strangulating obstruction as well as internal hernia. This knowledge may assume a critical importance for surgeons to decide on therapy. In this article, we focus our attention on the imaging (particularly CT) in small bowel complications following abdominal surgery

    2002-01-01

    Purpose: Spinal meningeal Gd-DTPA enhancement after cranial surgery is a known observation of a not well understood underlying mechanism. This paper demonstrates that this MRI finding is a normal meningeal reaction to subarachnoid hemorrhage, which should not be mistaken for metastatic spread. Material and methods: Three pediatric patients were examined by MRI for metastatic spread of malignant infratentorial tumors along the spinal canal two to nine days after the removal of the primary cerebral lesion. The findings were compared with a control group that underwent cranial surgery (cyst resection or fenestration of the posterior cranial fossa) without major bleeding into the subarachnoid space. Unenhanced and enhanced sequences were obtained to prove that the high singal within the CSF is caused by an abnormal Gd-DTPA uptake and not by methemoglobin. Results: Meningeal enhancement was observed in all patients with intraoperative bleeding resembling subarachnoid masses on enhanced T 1 -weighted images. This was not present in any patient of the control group. This finding lasts for approximately two weeks. Conclusion: The meningeal enhancement renders immediate postoperative studies inconclusive for the detection of metastatic spread. Consequently, the obligatory tumor staging along the spinal canal should ideally be done prior to the resection of a cerebral tumor. (orig.) [de

    The results of radiation therapy for metastatic spinal tumors were evaluated in terms of pain relief, improvement of neurological impairment, and survival. Between 1986 and 1995, 52 symptomatic patients with metastatic spinal tumors treated with radiation therapy were evaluated. The patients all received irradiation of megavoltage energy. Therapeutic efficacy was evaluated in terms of pain relief and improvement of neurological impairment. Pain relief was observed in 29 (61.7%) of 47 patients with pain. Therapy was effective for 17 (70.8%) of 24 patients without neurological impairment, and efficacy was detected in 12 (52.2%) of 23 patients with neurological impairment. Improvement of neurological symptoms was obtained in seven (25.0%) of 28 patients with neurological impairment. Radiation therapy was effective for pain relief in patients with metastatic spinal tumors. In patients with neurological impairment, less pain relief was observed than in those without impairment. Improvement of neurological impairment was restricted, but radiation therapy was thought to be effective in some cases in the early stage of neurological deterioration. Radiation therapy for metastatic spinal tumors contraindicated for surgery was considered effective for improvement of patients' activities of daily living. (author)

    It has been reported that rat L5/6 lumbar discs are innervated mainly by L2 dorsal root ganglion neurons. We previously reported that L2 spinal nerve infiltration was effective for discogenic low back pain (DLBP) patients, although the diagnosis was based only on the results of physical examination, plain films, and magnetic resonance imaging (MRI). The purpose of the current study was to evaluate L2 spinal nerve block for DLBP patients retrospectively based on MRI findings and surgical results. A total of 62 patients with only LBP and no accompanying radicular pain were investigated. Patients had only one level of disc degeneration on MRI. When pain was provoked during discography, we performed surgery at the next stage (40 patients). In all, 22 patients were excluded owing to negative discography results. Of the 40 patients, we evaluated 25 strictly selected patients suffering from DLBP. DLBP was diagnosed when the patient experienced pain relief at least 2 years after anterior lumbar interbody fusion. Fifteen patients who did not show pain relief after surgery were used for the non-DLBP group. L2 spinal nerve infiltration using 1.5 ml of lidocaine was performed in all 40 patients before surgery. The visual analogue scale (VAS) score after L2 spinal nerve infiltration was recorded, and an association of L2 spinal nerve infiltration and DLBP was explored. Low back pain scores assessed using the VAS score, the Japanese Orthopedic Association score, and the Oswestry Disability Index score in the two groups were not significantly different. L2 spinal nerve infiltration was effective for 27 patients but not effective for 13 patients; the VAS score after 15 min and 2 h improved in the DLBP group compared with that of the non-DLBP group (P<0.05). L2 spinal nerve infiltration was more effective in DLBP patients (21 patients, 84%) than in the non-DLBP group (6 patients, 40%) (P<0.05). In the current study, L2 spinal nerve infiltration was effective in 84% of selected DLBP

    Spinal epidural abscesses are an uncommon cause of spinal cord injury but, depending on the size and presence of neurological deficits, urgent neurosurgical intervention may be required. We present a unique case of a patient presenting with a spinal epidural collection several days after a fall. While a spinal epidural hematoma was suspected based on the patient's history and MRI findings, a spinal epidural abscess was found during surgery. The patient underwent laminectomy and instrumented fusion with successful treatment of her infection.

    A 54-year-old woman presented a midline clival tumor manifesting as right abducens palsy in May 1997. Magnetic resonance (MR) imaging revealed a midline clival tumor. She underwent surgery twice with the transsphenoidal approach and gamma knife surgery for residual tumor. The histological diagnosis was chordoma. MR imaging revealed that the tumor had extended to the right cerebellopontine angle, with spinal seeding in February 2002. She underwent partial removal of the right cerebellopontine angle tumor. The histological diagnosis was chordoma with slight nuclear atypism. She died 5 years and 5 months after the first gamma knife surgery. Autopsy revealed multiple areas of spinal seeding. Histological examination confirmed malignant transformation with unique epithelial characteristics, possibly caused by gamma knife surgery. (author)

  6. Obesity is independently associated with spinal anesthesia outcomes: a prospective observational study.

    Full Text Available The influence of body-mass index (BMI on spinal anesthesia is still controversial, with discrepant results reported in previous studies. To compare spinal anesthesia in obese and non-obese subjects, the anesthesia profiles in patients who underwent spinal anesthesia using intrathecal hyperbaric bupivacaine were compared. A total of 209 patients undergoing elective total knee replacement arthroplasty (TKRA surgery under spinal anesthesia were divided into an NO (non-obese group (BMI < 30 kg/m2, n = 141 and an O (obese group (BMI ≥ 30 kg/m2, n = 68. Anesthesia was deemed successful if a bilateral T12 sensory block occurred within 15 minutes of intrathecal drug administration, and if the level of sensory block was higher than T12 when the surgery ended. Logistic regression analysis with multiple variables known to influence spinal anesthesia was performed to identify which parameters independently determined the spinal anesthesia outcome. Similar doses of bupivacaine were administered to the NO and O groups. The incidence of anesthesia failure was significantly lower in the O group [n = 43 (30.5% in the NO group vs. n = 10 (18.9% in the O group, p = 0.014]. The independent predictors for successful anesthesia in all patients were dose of hyperbaric bupivacaine [odds ratio (OR 2.12, 95% CI: 1.64-2.73] and obese status (BMI ≥ 30 kg/m2, OR 2.86, 95% CI: 1.25-6.52. Time to first report of postoperative pain and time to first self-void were significantly longer in the O group. These results suggest that the duration of block with hyperbaric bupivacaine is prolonged in obese patients and obesity is independently associated with spinal anesthesia outcomes, as is bupivacaine dosage. A further study enrolling patients with morbid obesity and using a fixed bupivacaine dosage is required to confirm the effect of obesity on spinal anesthesia.

    Full Text Available Abstract Background This review summarizes what is known about the pathological processes (e.g. structural and functional changes, by which spinal curvatures develop and evolve into spinal deformities. Methods Comprehensive review of articles (English language only published on 'scoliosis,' whose content yielded data on the pathological changes associated with spinal curvatures. Medline, Science Citation Index and other searches yielded > 10,000 titles each of which was surveyed for content related to 'pathology' and related terms such as 'etiology,' 'inheritance,' 'pathomechanism,' 'signs and symptoms.' Additional resources included all books published on 'scoliosis' and available through the Arizona Health Sciences Library, Interlibrary Loan, or through direct contact with the authors or publishers. Results A lateral curvature of the spine–'scoliosis'–can develop in association with postural imbalance due to genetic defects and injury as well as pain and scarring from trauma or surgery. Irrespective of the factor that triggers its appearance, a sustained postural imbalance can result, over time, in establishment of a state of continuous asymmetric loading relative to the spinal axis. Recent studies support the longstanding hypothesis that spinal deformity results directly from such postural imbalance, irrespective of the primary trigger, because the dynamics of growth within vertebrae are altered by continuous asymmetric mechanical loading. These data suggest that, as long as growth potential remains, evolution of a spinal curvature into a spinal deformity can be prevented by reversing the state of continuous asymmetric loading. Conclusion Spinal curvatures can routinely be diagnosed in early stages, before pathological deformity of the vertebral elements is induced in response to asymmetric loading. Current clinical approaches involve 'watching and waiting' while mild reversible spinal curvatures develop into spinal deformities with

    Full Text Available Background: Pedicle screw instrumentation has been widely used for spinal stabilisation following spinal injury with variable results. The controversial points associated with spinal injury are effects of canal compromise and decompression on neurological status. Methods: Thirty four patients of unstable thoraco-lumbar fracture with or without neuro-deficit were treated by decompression and stabilisation with VSP system and followed up for 22 - 39 months (mean 29 months. The results were evaluated by neurological recovery (ASIA score, pain relief, loss of surgical correction and functional rehabilitation (FIM score. Results: We achieved a mean post-operative correction of the kyphotic deformity by 14 degrees and an average gain of 30.2% in the canal diameter by decompression. However no correlation was established between degree of canal compromise before or after the surgery with the final neurological outcome. Conclusion: Although the infrastructure for spinal injury management in developing countries is inadequate in many aspects, we find that it is still possible to achieve results, which are comparable with standard literature by adequate decompression and stabilisation followed by appropriate rehabilitation according to the social and cultural demands of the patients.

    Lumbar spine surgery is typically performed under general anesthesia, although spinal anesthesia can also be used. Given the prevalence of lumbar spine surgery, small differences in cost between the two anesthetic techniques have the potential to make a large impact on overall healthcare costs. We sought to perform a cost comparison analysis of spinal versus general anesthesia for lumbar spine operations. Following Institutional Review Board approval, a retrospective cohort study was performed from 2009-2012 on consecutive patients undergoing non-instrumented, elective lumbar spine surgery for spondylosis by a single surgeon. Each patient was evaluated for both types of anesthesia, with the decision for anesthetic method being made based on a combination of physical status, anatomical considerations, and ultimately a consensus agreement between patient, surgeon, and anesthesiologist. Patient demographics and clinical characteristics were compared between the two groups. Operating room costs were calculated whilst blinded to clinical outcomes and reported in percentage difference. General anesthesia (n=319) and spinal anesthesia (n=81) patients had significantly different median operative times of 175 ± 39.08 and 158 ± 32.75 minutes, respectively (plumbar spine surgery. It has the potential to reduce operative times, costs, and possibly, complications. Further prospective evaluation will help to validate these findings. Copyright © 2014 Elsevier Ltd.

    To compare measurements of motor evoked potential latency stimulated either magnetically (mMEP) or electrically (eMEP) and central motor conduction time (CMCT) made pre-operatively in conscious patients using transcranial and intra-operatively using electrical cortical stimulation before and after successful instrumentation for the treatment of adolescent idiopathic scoliosis. A group initially of 51 patients with adolescent idiopathic scoliosis aged 12-19 years was evaluated pre-operatively in the outpatients' department with transcranial magnetic stimulation. The neurophysiological data were then compared statistically with intra-operative responses elicited by transcranial electrical stimulation both before and after successful surgical intervention. MEPs were measured as the cortically evoked compound action potentials of Abductor hallucis. Minimum F-waves were measured using conventional nerve conduction methods and the lower motor neuron conduction time was calculated and this was subtracted from MEP latency to give CMCT. Pre-operative testing was well tolerated in our paediatric/adolescent patients. No neurological injury occurred in any patient in this series. There was no significant difference in the values of mMEP and eMEP latencies seen pre-operatively in conscious patients and intra-operatively in patients under anaesthetic. The calculated quantities mCMCT and eCMCT showed the same statistical correlations as the quantities mMEP and eMEP latency. The congruency of mMEP and eMEP and of mCMCT and eCMCT suggests that these measurements may be used comparatively and semi-quantitatively for the comparison of pre-, intra-, and post-operative spinal cord function in spinal deformity surgery.

    As a consumer-driven industry, cosmetic plastic surgery is subject to ebbs and flows as the economy changes. There have been many predictions about the short, intermediate, and long-term impact on cosmetic plastic surgery as a result of difficulties in the current economic climate, but no studies published in the literature have quantified a direct correlation. The authors investigate a possible correlation between cosmetic surgery volume and the economic trends of the three major US stock market indices. A volume analysis for the time period from January 1992 to October 2008 was performed (n = 7360 patients, n = 8205 procedures). Four cosmetic procedures-forehead lift (FL), rhytidectomy (Rh), breast augmentation (BA), and liposuction (Li)-were chosen; breast reduction (BRd), breast reconstruction (BRc), and carpal tunnel release (CTR) were selected for comparison. Case volumes for each procedure and fiscal quarter were compared to the trends of the S&P 500, Dow Jones (DOW), and NASDAQ (NASD) indices. Pearson correlation statistics were used to evaluate a relationship between the market index trends and surgical volume. P values indices. FL (n =312) only correlated to the NASD (P = .021) and did not reach significance with the S&P 500 (P = .077) or DOW (P = .14). BRd and BRc demonstrated a direct correlation to two of the three stock market indices, whereas CTR showed an inverse (ie, negative) correlation to two of the three indices. This study, to our knowledge, is the first to suggest a direct correlation of four cosmetic and two reconstructive plastic surgery procedures to the three major US stock market indices and further emphasizes the importance of a broad-based plastic surgery practice in times of economic recession.

    The blood-spinal cord barrier (BSCB) is a specialized protective barrier that regulates the movement of molecules between blood vessels and the spinal cord parenchyma. Analogous to the blood-brain barrier (BBB), the BSCB plays a crucial role in maintaining the homeostasis and internal environmental stability of the central nervous system (CNS). After spinal cord injury (SCI), BSCB disruption leads to inflammatory cell invasion such as neutrophils and macrophages, contributing to permanent neurological disability. In this review, we focus on the major proteins mediating the BSCB disruption or BSCB repair after SCI. This review is composed of three parts. Section 1. SCI and the BSCB of the review describes critical events involved in the pathophysiology of SCI and their correlation with BSCB integrity/disruption. Section 2. Major proteins involved in BSCB disruption in SCI focuses on the actions of matrix metalloproteinases (MMPs), tumor necrosis factor alpha (TNF-α), heme oxygenase-1 (HO-1), angiopoietins (Angs), bradykinin, nitric oxide (NO), and endothelins (ETs) in BSCB disruption and repair. Section 3. Therapeutic approaches discusses the major therapeutic compounds utilized to date for the prevention of BSCB disruption in animal model of SCI through modulation of several proteins.

    The aim of this study was to compare the clinical effects and characteristics of hyperbaric and hypobaric levobupivacaine for unilateral spinal anaesthesia. Sixty patients were randomly allocated into two groups to receive either 7.5 mg (1.5 ml) hyperbaric levobupivacaine 0.5% or 7.5 mg (4 ml) hypobaric levobupivacaine 0.1875% for elective arthroscopic surgery of the knee under spinal anaesthesia. The level and duration of sensory block, intensity and duration of motor block were recorded. Unilateral sensory block was observed in 27 patients (90%) in the hyperbaric group and 24 patients (80%) in the hypobaric group in the lateral position. After 15 minutes, patients were turned to supine to redistribute the spinal block toward the non-operative side, but spinal anaesthesia was still unilateral in 18 patients (60%) in the hyperbaric group and 10 patients (33%) in the hypobaric group (P = 0.038). Time to readiness for home discharge and complete recovery of sensory block were similar in both groups. In the hyperbaric group, the motor block scores were higher on the operative side during first 10 minutes than they were in the hypobaric group (P hyperbaric group (P = 0.01). Hyperbaric and hypobaric levobupivacaine both provided satisfactory unilateral spinal anaesthesia with good haemodynamic stability for arthroscopic surgery, but with more frequent unilateral spinal anaesthesia in the hyperbaric group.

    Because neither the degree of constriction of the spinal canal considered to be symptomatic for lumbar spinal stenosis nor the relationship between the clinical appearance and the degree of a radiologically verified constriction is clear, a correlation of patient's disability level and radiographic constriction of the lumbar spinal canal is of interest. The aim of this study was to establish a relationship between the degree of radiologically established anatomical stenosis and the severity of self-assessed Oswestry Disability Index in patients undergoing surgery for degenerative lumbar spinal stenosis. Sixty-three consecutive patients with degenerative lumbar spinal stenosis who were scheduled for elective surgery were enrolled in the study. All patients underwent preoperative magnetic resonance imaging and completed a self-assessment Oswestry Disability Index questionnaire. Quantitative image evaluation for lumbar spinal stenosis included the dural sac cross-sectional area, and qualitative evaluation of the lateral recess and foraminal stenosis were also performed. Every patient subsequently answered the national translation of the Oswestry Disability Index questionnaire and the percentage disability was calculated. Statistical analysis of the data was performed to seek a relationship between radiological stenosis and percentage disability recorded by the Oswestry Disability Index. Upon radiological assessment, 27 of the 63 patients evaluated had severe and 33 patients had moderate central dural sac stenosis; 11 had grade 3 and 27 had grade 2 nerve root compromise in the lateral recess; 22 had grade 3 and 37 had grade 2 foraminal stenosis. On the basis of the percentage disability score, of the 63 patients, 10 patients demonstrated mild disability, 13 patients moderate disability, 25 patients severe disability, 12 patients were crippled and three patients were bedridden. Radiologically, eight patients with severe central stenosis and nine patients with moderate

    A descriptive and prospective study on the practice of ambulatory major surgery to eliminate benign tumours of the thyroid gland, was carried out in the General Surgery Service of 'Dr. Joaquin Castillo Duany' Teaching Clinical Surgical Hospital in Santiago de Cuba during the years 1996-2008, both included, through a previous clinical evaluation of 74 patients in the Endocrinology Outpatient Department, where it was decided that they could definitely have a surgical treatment. The female sex, the age groups from 31 to 45 years, the hemithyroidectomy as surgical technique, acupuncture as analgesic procedure and the follicular adenoma as cytohistological result prevailed in the case material. Mild complications occurred in 5 members of the sample, but recovery was absolute in all, so that even 72 of them were discharged before the 24 hours. Due to its good acceptance, this surgical method is beneficial for patient and hospital institutions.(author)

    Spinal cord stimulation (SCS) is now established as the primary treatment for failed back surgery syndrome (FBSS). Commonly, patients with chronic pain and FBSS often report symptoms of anxiety and depression resulting from this condition. These factors can modulate and amplify the pain experience, therefore, further challenging treatment success. This study examined the efficacy of SCS on alleviating the symptoms of anxiety and depression associated with chronic pain as well as pain intensity in a group of patients with FBSS. A convenience sample (n = 26) was selected for participation. Questionnaires [Hospital Anxiety and Depression Scale (HADS) and Brief Pain Inventory Short Form (BPI-SF)] were completed and examined pre and post spinal cord implant. Analysis of the data 1 year following SCS indicates that there was a statistical significant improvement in the symptoms of depression and anxiety reported as well as pain intensity in all participants (p anxiety and depression scores on the HADS were significantly lower compared to baseline (p anxiety and depression with an associated reduction in opioid consumption.

    From September 1987 through May 1989, magnetic resonance imaging (MRI) has been performed in 58 patients with myelopathy and 9 patients with spinal cord injuries. This study was designed to determine the rate of spinal cord stricture and changes of signal intensities. Increased signal intensity on T2-weighted images was more frequently observed than decreased intensity on T1-weighted images in the group of myelopathy (19/58 vs 10/58). In the group of spinal cord injuries, however, there was no significant difference in the incidence between increased intensity on T2-weighted images (4/9) and decreased intensity on T1-weighted images (7/9). Twelve patients with chronic compressive spinal myelopathy tended to have an increased intensity on T2-weighted images. In such cases, although JOA scores were low before surgery, signal intensity returned to that without marked signal changes. In chronic compressive cervical myelopathy, the degree of preoperative compression was the same as the postoperative JOA scores. Regarding cervical spinal injury, there was a good correlation between the size of low signal area and the degree of paralysis. (N.K.)

    Full Text Available Spinal epidermoid cysts, whether congenital or iatrogenic, are relatively uncommon in the spinal cord. When they occur, the typical location is in the subdural, extramedullary space of the lumbo-sacral region. We describe an unusual presentation in a 3-year-old male child which mimicked astrocytoma clinicoradiologically. The child developed sudden onset of inability in walking and weakness of both lower limbs after a fall. There was a dramatic reversal of symptoms after surgery. Histopathology revealed an epidermoid cyst of the spine. On the first follow-up visit at 3 months, the child was asymptomatic.

  3. Spinal SIRT1 activation attenuates neuropathic pain in mice.

    Directory of Open Access Journals (Sweden)

    Haijun Shao

    Full Text Available Abnormal histone acetylation occurs during neuropathic pain through an epigenetic mechanism. Silent information regulator 1 (sir2 or SIRT1, a NAD-dependent deacetylase, plays complex systemic roles in a variety of processes through deacetylating acetylated histone and other specific substrates. But the role of SIRT1 in neuropathic pain is not well established yet. The present study was intended to detect SIRT1 content and activity, nicotinamide (NAM and nicotinamide adenine dinucleotide (NAD in the spinal cord using immunoblotting or mass spectroscopy over time in mice following chronic constriction injury (CCI or sham surgery. In addition, the effect of intrathecal injection of NAD or resveratrol on thermal hyperalgesia and mechanical allodynia was evaluated in CCI mice. Finally, we investigated whether SIRT1 inhibitor EX-527 could reverse the anti-nociceptive effect of NAD or resveratrol. It was found that spinal SIRT1 expression, deacetylase activity and NAD/NAM decreased significantly 1, 3, 7, 14 and 21 days after CCI surgery as compared with sham group. In addition, daily intrathecal injection of 5 µl 800 mM NAD 1 h before and 1 day after CCI surgery or single intrathecal injection of 5 µl 90 mM resveratrol 1 h before CCI surgery produced a transient inhibitory effect on thermal hyperalgesia and mechanical allodynia in CCI mice. Finally, an intrathecal injection of 5 µl 1.2 mM EX-527 1 h before NAD or resveratrol administration reversed the anti-nociceptive effect of NAD or resveratrol. These data indicate that the reduction in SIRT1 deacetylase activity may be a factor contributing to the development of neuropathic pain in CCI mice. Our findings suggest that the enhancement of spinal NAD/NAM and/or SIRT1 activity may be a potentially promising strategy for the prevention or treatment of neuropathic pain.

    Background: Extramedullary hematopoiesis (EMH) occurs in many disorders, including thalassemias and other hemoglobinopathies, and commonly presents in the spleen and liver. We present a case of spinal cord compression in a patient with beta-thalassemia intermedia, and review the literature and available treatment options. Patient and Methods: A 35-year-old black female with beta-thalassemia intermedia presented with a 3-week history of back pain and lower extremity weakness. Neurologic examination was consistent with spinal cord compression, and gadolinium enhanced magnetic resonance imaging (MRI) confirmed this diagnosis. She was given intravenous steroids and radiotherapy was begun in 200 cGy fractions to a total dose of 2000 cGy. Results: At the completion of radiotherapy the patient was ambulatory with mild residual weakness. MRI scans 16 months later showed smaller, but persistent masses, and she remains asymptomatic 5 years from her diagnosis. Conclusion: Recognition of spinal cord EMH requires prompt physical examination and MRI for accurate diagnosis. EMH can be managed with radiation, surgery, transfusions, or a combination of these therapies. Radiation in conservative doses of (750-3500 cGy) is non-invasive, avoids the surgical risks of potentially severe hemorrhage and incomplete resection, and has a high complete remission rate in the majority of patients.

    Postoperative hematomas are one of the most frequent complications following aesthetic surgery. Identifying risk factors for hematoma has been limited by underpowered studies from single institution experiences. To examine the incidence and identify independent risk factors for postoperative hematomas following cosmetic surgery utilizing a prospective, multicenter database. A prospectively enrolled cohort of patients who underwent aesthetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Primary outcome was occurrence of major hematomas requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis was used to identify potential risk factors for hematomas including age, gender, body mass index (BMI), smoking, diabetes, type of surgical facility, procedure by body region, and combined procedures. Of 129,007 patients, 1180 (0.91%) had a major hematoma. Mean age (42.0 ± 13.0 years vs 40.9 ± 13.9 years, P hematomas. Males suffered more hematomas than females (1.4% vs 0.9%, P Hematoma rates were higher in patients undergoing combined procedures compared to single procedures (1.1% vs 0.8%, P hematoma included age (Relative Risk [RR] 1.01), male gender (RR 1.98), the procedure being performed in a hospital setting rather than an office-based setting (RR 1.68), combined procedures (RR 1.35), and breast procedures rather than the body/extremity and face procedures (RR 1.81). Major hematoma is the most common complication following aesthetic surgery. Male patients and those undergoing breast or combined procedures have a significantly higher risk of developing hematomas. 2. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

    A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used. (author)

    The pain associated with spinal puncture is severe, and the memory of this uncomfortable procedure often deters patients from undergoing the procedure again. Therefore, it is important to make the patient as comfortable as possible when this procedure is performed. We administrated a low-dose (1-2.5 mg) of midazolam intravenously several minutes before conducting a spinal-tap in 200 patients undergoing elective surgery of the lower limb. The dose of midazolam used was based on the patient's age and weight, and we investigated remaining of a memory concerning the spinal-tap procedure and side effects of midazolam at the end of surgery. Memory of the spinal-tap procedure remained in 14.0%, 1.9%, and 32.7% of the patients who had received benzodiazepine preoperatively and in 25.0%, 40.0%, and 60.9% of the patients who hadn't received benzodiazepine preoperatively in the age group or =70 years, respectively. No patient experienced severe respiratory depression, but an excessive sedation or restlessness was experienced in 1.6%, 4.8%, and 5.2% of the patients. In the patients aged memory concerning the spinal-tap procedure; however, it is important to note that the number of side effects associated with this procedure increases in patients aged > or =60 years.

    Full Text Available Background: Superior mesenteric artery (SMA syndrome has been reported as an uncommon condition of external vascular compression of the SMA particularly after rapid weight loss, body casts, or after corrective surgery for spinal deformities, usually within the first few weeks after surgery. Methods: This is a retrospective report of a case of a non-verbal autistic female patient who started to develop SMA syndrome at the age of 16, 4 years after posterior spinal fusion surgery for scoliosis. She was treated conservatively by increasing oral caloric intake, which resulted in increased body weight and relief of symptoms. Results: Seen at 10 years’ follow up, the patient is doing well, and is functional within the limits of her suboptimal cognitive and verbal conditions. She maintains good trunk balance with solid spinal fusion and intact instrumentation at latest follow up. Conclusion: Spinal surgeons should maintain a high index of suspicion for diagnosis of SMA syndrome even years after scoliosis surgery, especially for patients with communication problems, like the case we present here. Appropriate conservative measures can succeed in relieving the symptoms, increasing body weight, and preventing complications including the risk of death.

    Purpose: To perform a review of the 40-year University of Florida experience treating spinal and paraspinal Ewing tumors. Patients and Methods: A total of 27 patients were treated between 1965 and 2007. For local management, 21 patients were treated with radiotherapy (RT) alone and 6 with surgery plus RT. All patients with metastatic disease were treated with RT alone. The risk profiles of each group were otherwise similar. The median age was 17 years, and the most frequent subsite was the sacral spine (n = 9). The median potential follow-up was 16 years. Results: The 5-year actuarial overall survival, cause-specific survival, and local control rate was 62%, 62%, and 90%, respectively. For the nonmetastatic subset (n = 22), the 5-year overall survival, cause-specific survival, and local control rate was 71%, 71%, and 89%, respectively. The local control rate was 84% for patients treated with RT alone vs. 100% for those treated with surgery plus RT. Patients who were >14 years old and those who were treated with intensive therapy demonstrated superior local control. Of 9 patients in our series with Frankel C or greater neurologic deficits at presentation, 7 experienced a full recovery with treatment. Of the 27 patients, 37% experienced Common Toxicity Criteria Grade 3 or greater toxicity, including 2 deaths from sepsis. Conclusion: Aggressive management of spinal and paraspinal Ewing tumors with RT with or without surgery results in high toxicity but excellent local control and neurologic outcomes. Efforts should be focused on identifying disease amenable to combined modality local therapy and improving RT techniques.

    This is a case-control study. The present study aimed to compare the cross-sectional areas of the psoas major and multifidus muscles between elderly patients with adult spinal deformity (ASD) and age-matched and body weight-matched controls, and to evaluate the associations between the cross-sectional areas of these muscles and the severity of spinal deformity. The study included 49 female kyphosis patients with mild scoliosis (Cobb angle muscles were calculated using preoperative L4/L5 axial computed tomography images. In group D, the following spinopelvic parameters were assessed: sagittal vertical axis, pelvic tilt, pelvic incidence, lumbar lordosis, and thoracic kyphosis. The relationships between the muscle cross-sectional areas and spinopelvic parameters were evaluated. The cross-sectional area of the multifidus muscle was lower in group D than in group C. However, the cross-sectional area of the psoas major muscle was not different between the 2 groups. In multiple regression analysis, the cross-sectional area of the multifidus muscle was significantly associated with all spinopelvic parameters. The cross-sectional area of the multifidus muscle might be lower in elderly patients with ASD than in controls. In the elderly population, the severity of sagittal spinal deformity might be correlated with the cross-sectional area of the multifidus muscle. Therefore, muscle imbalances between the flexors and extensors of the spine could participate in the pathology of ASD.

  15. Maladaptive spinal plasticity opposes spinal learning and recovery in spinal cord injury

    2012-10-01

    Full Text Available Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI. Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. The mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain pathways in the spinal cord may emerge with certain patterns of activity, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after spinal cord injury. We review these basic phenomena, discuss the cellular and molecular mechanisms, and discuss implications of these findings for improved rehabilitative therapies after spinal cord injury.

  16. RNAseq Analyses Identify Tumor Necrosis Factor-Mediated Inflammation as a Major Abnormality in ALS Spinal Cord.

    Directory of Open Access Journals (Sweden)

    David G Brohawn

    Full Text Available ALS is a rapidly progressive, devastating neurodegenerative illness of adults that produces disabling weakness and spasticity arising from death of lower and upper motor neurons. No meaningful therapies exist to slow ALS progression, and molecular insights into pathogenesis and progression are sorely needed. In that context, we used high-depth, next generation RNA sequencing (RNAseq, Illumina to define gene network abnormalities in RNA samples depleted of rRNA and isolated from cervical spinal cord sections of 7 ALS and 8 CTL samples. We aligned >50 million 2X150 bp paired-end sequences/sample to the hg19 human genome and applied three different algorithms (Cuffdiff2, DEseq2, EdgeR for identification of differentially expressed genes (DEG's. Ingenuity Pathways Analysis (IPA and Weighted Gene Co-expression Network Analysis (WGCNA identified inflammatory processes as significantly elevated in our ALS samples, with tumor necrosis factor (TNF found to be a major pathway regulator (IPA and TNFα-induced protein 2 (TNFAIP2 as a major network "hub" gene (WGCNA. Using the oPOSSUM algorithm, we analyzed transcription factors (TF controlling expression of the nine DEG/hub genes in the ALS samples and identified TF's involved in inflammation (NFkB, REL, NFkB1 and macrophage function (NR1H2::RXRA heterodimer. Transient expression in human iPSC-derived motor neurons of TNFAIP2 (also a DEG identified by all three algorithms reduced cell viability and induced caspase 3/7 activation. Using high-density RNAseq, multiple algorithms for DEG identification, and an unsupervised gene co-expression network approach, we identified significant elevation of inflammatory processes in ALS spinal cord with TNF as a major regulatory molecule. Overexpression of the DEG TNFAIP2 in human motor neurons, the population most vulnerable to die in ALS, increased cell death and caspase 3/7 activation. We propose that therapies targeted to reduce inflammatory TNFα signaling may be

    This study sought to observe the effect of the combination of edaravone and neural stem cell (NSC) transplantation on the repair of complete spinal cord transection in rats. Eighty adult female Sprague-Dawley (SD) rats were used to establish the injury model of complete spinal cord transection at T9. Animals were divided randomly into four groups (N = 20 each): control, edaravone, transplantation, and edaravone + transplantation. The recovery of spinal function was evaluated with the Basso, Beattie, Bresnahan (BBB) rating scale on days 1, 3, and 7 each week after the surgery. After 8 weeks, the BBB scores of the control, edaravone, transplantation, and combination groups were 4.21 ± 0.11, 8.46 ± 0.1, 8.54 ± 0.13, and 11.21 ± 0.14, respectively. At 8 weeks after surgery, the spinal cord was collected; the survival and transportation of transplanted cells were observed with PKH-26 labeling, and the regeneration and distribution of spinal nerve fibers with fluorescent-gold (FG) retrograde tracing. Five rats died due to the injury. PKH-26-labeled NSCs had migrated into the spinal cord. A few intact nerve fibers and pyramidal neurons passed the injured area in the transplantation and combination groups. The numbers of PKH-26-labeled cells and FG-labeled nerve fibers were in the order: combination group > edaravone group and transplantation group > control group (P edaravone can enhance the survival and differentiation of NSCs in injured areas; edaravone with NSC transplantation can improve the effectiveness of spinal cord injury repair in rats.

    Postoperative pneumonia (POP) is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC) surgery. Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016. We individually traced each OC patient for a period to discharge from the hospital or 45 days after surgery, whichever occur later. The incidence of POP after major OC surgery with free flap construction or major OC surgery was 11.6% or 4.5%, respectively. Patient-related risk factors for POP were male sex, T stage, N stage, clinical stage and preoperative serum albumin level. Among the investigated procedure-related variables, incision grade, mandibulectomy, free flap reconstruction, tracheotomy, intraoperative blood loss, and the length of the operation were shown to be associated with the development of POP. Postoperative hospital stay was also significantly related to increased incidence of POP. Using a multivariable logistic regression model, we identified male sex, preoperative serum albumin level, operation time and postoperative hospital stay as independent risk factors for POP. Several perioperative risk factors can be identified that are associated with POP. At-risk oral cancer patients should be subjected to intensified postoperative pulmonary care.

    A 25-year-old woman presented with a four-year history of progressive right-lower-extremity weakness and atrophy and a left hemisensory deficit was found. Metrizamide-enhanced spinal CT scan showed an intramedullary lesion at the level of T1-T2; this had expanded the cord in fusiform fashion but showed no evidence of a cystic component. Surgical resection was performed and the pathological diagnosis was cavernous hemangioma. Two and one-half years later, her left hemisensory deficit was worsening and a spinal MRI showed high signal intensity mass in the region of the previous surgery consistent with chronic hematoma which was re-evacuated with some improvement in the patient's neurological condition.

    Meningitis after neurosurgery can result in severe morbidity and high mortality. Incidence varies among regions and limited data are focused on meningitis after major craniotomy. This retrospective cohort study aimed to determine the incidence, risk factors and microbiological spectrum of postcraniotomy meningitis in a large clinical center of Neurosurgery in China. Patients who underwent neurosurgeries at the Department of Neurosurgery in Huashan Hospital, the largest neurosurgery center in Asia and the Pacific, between 1st January and 31st December, 2008 were selected. Individuals with only shunts, burr holes, stereotactic surgery, transsphenoidal or spinal surgery were excluded. The complete medical records of each case were reviewed, and data on risk factors were extracted and evaluated for meningitis. A total of 65 meningitides were identified among 755 cases in the study, with an incidence of 8.60%. The risk of meningitis was increased by the presence of diabetes mellitus (odds ratio [OR], 6.27; P = 0.009), the use of external ventricular drainage (OR, 4.30; P = 0.003) and the use of lumbar drainage (OR, 17.23; PMeningitis remains an important source of morbidity and mortality after major craniotomy. Diabetic patients or those with cerebral spinal fluid shunts carry significant high risk of infection. Thus, identification of the risk factors as soon as possible will help physicians to improve patient care.

    Full Text Available Objective: To demonstrate the feasibility of using da Vinci robotic surgical system to perform spinal surgery. Methods: Magnetic resonance imaging (MRI of a 29-year-old female patient complaining right pelvic pain for 1 month revealed a 17x8x10 cm non-homogeneous dumbbell shape encapsulated mass with cystic change located in the pelvic cavity and caused an anterior displacement of urinary bladder and colon. Results: There was no systemic complication and pain decrease 24 hours after surgery and during 2 years of follow up. The patient started a diet 6 hours after the surgery and was discharged 72 hours after the surgery. The pathological diagnosis of the tumor was schwannoma. Conclusions: Giant dumbbell shape presacral schwannomas are rare tumours and their surgical treatment is challenging because of the complex anatomy of the presacral. Clinical application of da Vinci robotic surgical system in the spinal surgical field is currently confined to the treatment of some specific diseases or procedures. However, robotic surgery is expected to play a practical future role as it is minimally invasive. The advent of robotic technology will prove to be a boon to the neurosurgeon.

    To examine implementing an enhanced recovery after surgery (ERAS) protocol for women undergoing major gynecologic surgery at an academic institution and compare surgical outcomes before and after implementation. Two ERAS protocols were developed: a full pathway using regional anesthesia for open procedures and a light pathway without regional anesthesia for vaginal and minimally invasive procedures. Enhanced recovery after surgery pathways included extensive preoperative counseling, carbohydrate loading and oral fluids before surgery, multimodal analgesia with avoidance of intravenous opioids, intraoperative goal-directed fluid resuscitation, and immediate postoperative feeding and ambulation. A before-and-after study design was used to compare clinical outcomes, costs, and patient satisfaction. Complications and risk-adjusted length of stay were drawn from the American College of Surgeons' National Surgical Quality Improvement Program database. On the ERAS full protocol, 136 patients were compared with 211 historical controls and the median length of stay was reduced (2.0 compared with 3.0 days; P=.007) despite an increase in National Surgical Quality Improvement Program-predicted length of stay (2.5 compared with 2.0 days; P=.009). Reductions were seen in median intraoperative morphine equivalents (0.3 compared with 12.7 mg; Pcontrols and demonstrated decreased intraoperative and postoperative morphine equivalents (0.0 compared with 13.0 mg; Pcontrol, nurses keeping patients informed, and staff teamwork; 30-day total hospital costs were significantly decreased in both ERAS groups. Implementation of ERAS protocols in gynecologic surgery was associated with a substantial decrease in intravenous fluids and morphine administration coupled with reduction in length of stay for open procedures combined with improved patient satisfaction and decreased hospital costs.

    2018-01-01

    Background Postoperative pressure ulcers are important indicators of perioperative care quality, and are serious and expensive complications during critical care. This study aimed to identify perioperative risk factors for postoperative pressure ulcers. Methods This retrospective case-control study evaluated 2,498 patients who underwent major surgery. Forty-three patients developed postoperative pressure ulcers and were matched to 86 control patients based on age, sex, surgery, and comorbidities. Results The pressure ulcer group had lower baseline hemoglobin and albumin levels, compared to the control group. The pressure ulcer group also had higher values for lactate levels, blood loss, and number of packed red blood cell (pRBC) units. Univariate analysis revealed that pressure ulcer development was associated with preoperative hemoglobin levels, albumin levels, lactate levels, intraoperative blood loss, number of pRBC units, Acute Physiologic and Chronic Health Evaluation II score, Braden scale score, postoperative ventilator care, and patient restraint. In the multiple logistic regression analysis, only preoperative low albumin levels (odds ratio [OR]: 0.21, 95% CI: 0.05–0.82; P pressure ulcer development. A receiver operating characteristic curve was used to assess the predictive power of the logistic regression model, and the area under the curve was 0.88 (95% CI: 0.79–0.97; P pressure ulcer development after surgery.

    In malignant brain tumours which may disseminate staging, usually by cranial and spinal MRI is necessary. If MRI is performed in the postoperative period pitfalls should be considered. Nonspecific subdural contrast enhancement on spinal staging MRI is rarely reported after resection of posterior fossa tumours, which may be mistaken for dissemination of malignancy. We investigated the frequency of spinal subdural enhancement after posterior cranial fossa neurosurgery in children. We reviewed 53 postoperative spinal MRI studies performed for staging of paediatric malignant brain tumours, mainly infratentorial primitive neuroectodermal tumours 2-40 days after surgery. There was contrast enhancement in the spinal subdural space in seven cases. This was not seen in any of eight patients who had been operated upon for a supratentorial tumour. After resection of 45 posterior cranial fossa tumours the frequency of subdural enhancement was 15.5%. MRI showing subdural enhancement was obtained up to 25 days postoperatively. No patient with subdural enhancement had cerebrospinal fluid (CSF) examinations positive for tumour cells or developed dissemination of disease in the CSF. Because the characteristic appearances of subdural contrast enhancement, appropriate interpretation is possible; diagnosis of neoplastic meningitis should rarely be impeded. Because of the striking similarity to that in patients with a low CSF-pressure syndrome and in view of the fact that only resection of tumours of the posterior cranial fossa, usually associated with obstructive hydrocephalus, was followed by this type of enhancement one might suggest that rapid changes in CSF pressure are implicated, rather the effects of blood introduced into the spinal canal at surgery.

    In malignant brain tumours which may disseminate staging, usually by cranial and spinal MRI is necessary. If MRI is performed in the postoperative period pitfalls should be considered. Nonspecific subdural contrast enhancement on spinal staging MRI is rarely reported after resection of posterior fossa tumours, which may be mistaken for dissemination of malignancy. We investigated the frequency of spinal subdural enhancement after posterior cranial fossa neurosurgery in children. We reviewed 53 postoperative spinal MRI studies performed for staging of paediatric malignant brain tumours, mainly infratentorial primitive neuroectodermal tumours 2-40 days after surgery. There was contrast enhancement in the spinal subdural space in seven cases. This was not seen in any of eight patients who had been operated upon for a supratentorial tumour.

    Synaptic plasticity within the spinal cord has great potential to facilitate recovery of function after spinal cord injury (SCI). Spinal plasticity can be induced in an activity-dependent manner even without input from the brain after complete SCI. A mechanistic basis for these effects is provided by research demonstrating that spinal synapses have many of the same plasticity mechanisms that are known to underlie learning and memory in the brain. In addition, the lumbar spinal cord can sustain several forms of learning and memory, including limb-position training. However, not all spinal plasticity promotes recovery of function. Central sensitization of nociceptive (pain) pathways in the spinal cord may emerge in response to various noxious inputs, demonstrating that plasticity within the spinal cord may contribute to maladaptive pain states. In this review we discuss interactions between adaptive and maladaptive forms of activity-dependent plasticity in the spinal cord below the level of SCI. The literature demonstrates that activity-dependent plasticity within the spinal cord must be carefully tuned to promote adaptive spinal training. Prior work from our group has shown that stimulation that is delivered in a limb position-dependent manner or on a fixed interval can induce adaptive plasticity that promotes future spinal cord learning and reduces nociceptive hyper-reactivity. On the other hand, stimulation that is delivered in an unsynchronized fashion, such as randomized electrical stimulation or peripheral skin injuries, can generate maladaptive spinal plasticity that undermines future spinal cord learning, reduces recovery of locomotor function, and promotes nociceptive hyper-reactivity after SCI. We review these basic phenomena, how these findings relate to the broader spinal plasticity literature, discuss the cellular and molecular mechanisms, and finally discuss implications of these and other findings for improved rehabilitative therapies after SCI.

    Hospital readmission after surgery results in a substantial economic burden, and several recent studies have investigated the impact of race and ethnicity on hospital readmission rates, with the goal to identify hospitals and patients with high readmission risk. This single-institution, retrospective cohort study assesses the impact of race, along with other risk factors, on 30-day readmission rates following spinal surgery. This study is a single-institution retrospective cohort study with accrual from January 1, 2008, to December 31, 2010. Inclusion criteria included adult patients who underwent anterior and/or posterior spinal surgery. The primary aim of this study was to assess the impact of patient race and other risk factors for postoperative hospital readmission within 30days following spine surgery. A total of 1346 patients (654 male, 692 female) were included in the study. Overall, 159 patients (11.8%) were readmitted in the 30days following their surgery. Multivariate logistic regression found significant risk factors for 30-day readmission, including Black race (OR: 2.20, C.I. 95% (1.04, 4.64)) and total length of stay greater than 7days (OR: 4.73, C.I. 95% (1.72, 12.98)). Cervical surgery was associated with decreased odds of readmission (OR: 0.27, C.I. 95% (0.08, 0.91)). Our study demonstrates that race and length of hospital stay influence the incidence of 30-day readmission rates after spinal surgery. Studies such as ours will aid in identifying patients with postoperative readmission risk and help elucidate the underlying factors that may be contributing to disparities in readmission after surgery.

    OBJECTIVE Postoperative delirium is common in elderly patients undergoing spine surgery and is associated with a longer and more costly hospital course, functional decline, postoperative institutionalization, and higher likelihood of death within 6 months of discharge. Preoperative cognitive impairment may be a risk factor for the development of postoperative delirium. The aim of this study was to investigate the relationship between baseline cognitive impairment and postoperative delirium in geriatric patients undergoing surgery for degenerative scoliosis. METHODS Elderly patients 65 years and older undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Preoperative cognition was assessed using the validated Saint Louis University Mental Status (SLUMS) examination. SLUMS comprises 11 questions, with a maximum score of 30 points. Mild cognitive impairment was defined as a SLUMS score between 21 and 26 points, while severe cognitive impairment was defined as a SLUMS score of ≤ 20 points. Normal cognition was defined as a SLUMS score of ≥ 27 points. Delirium was assessed daily using the Confusion Assessment Method (CAM) and rated as absent or present on the basis of CAM. The incidence of delirium was compared in patients with and without baseline cognitive impairment. RESULTS Twenty-two patients (18%) developed delirium postoperatively. Baseline demographics, including age, sex, comorbidities, and perioperative variables, were similar in patients with and without delirium. The length of in-hospital stay (mean 5.33 days vs 5.48 days) and 30-day hospital readmission rates (12.28% vs 12%) were similar between patients with and without delirium, respectively. Patients with preoperative cognitive impairment (i.e., a lower SLUMS score) had a higher incidence of postoperative delirium. One- and 2-year patient reported outcomes scores were similar in patients with and without delirium. CONCLUSIONS

    Tumors of the spine in children are rare, and further clinical description is necessary. This study investigated epidemiology, interventions, and outcomes of pediatric patients with spine and spinal cord tumors. The National Inpatient Sample and Kids' Inpatient Database were used for the study. Outcomes were studied, and bivariate significant trends were analyzed in a multivariate setting. Analysis of 2870 patients between 2000 and 2009 found a median age of diagnosis of 11 years (Tables 1 and 2). Most were white (65.2%) and had private insurance (62.3%), and 46.8% of procedures were emergent operations. Treatment occurred at teaching (93.6%) and non-children's hospitals (81.1%). Overall mortality rate was 1.7%, non-routine discharges occurred at a rate 19.9%, complications at 21.1%, and average total charges were $66,087. A majority of patients (87.5%) had no intervention, and of those patients receiving treatment, 78.2% underwent surgery and 23.1% had radiotherapy. Treatment with surgery alone increased significantly over time (p spine and spinal cord tumors in children. Notably, a higher mortality rate is evident over time in addition to an increase in the proportion of patients undergoing surgery. The high percentage of emergent operations suggests a weak recognition of spine tumors in children and should prompt a call for increased awareness of this cancer. In spite of these findings, lack of tumor type identification was a limitation to this study.

    Full Text Available Abstract Introduction Encephalocele is a rare congenital abnormality of the central nervous system, where brain tissue protrudes from a defect in the skull. Some anomalies are associated with encephalocele. However, the association of spinal teratoma and encephalocele has not been reported in the English literature. Case presentation We report the case of an Iranian girl with a history of encephalocele surgery, who, at the age of four years, developed an intramedullary spinal teratoma, and discuss the pathogenesis of this association. Conclusion To the best of our knowledge, this is the first report of an association between encephalocele and spinal teratoma.

    We describe a case of rachipagus parasitic twin with spinal cord malformations (lipomyelomeningocele and tethered cord) in a 7-month-old Ethiopian infant. The parasitic mass had a well-formed foot, ankle and lower leg and a small sinus that resembled an anus. Magnetic resonance imaging scans revealed spinal malformations including a distal syringohydromyelia. The mass was successfully resected and the dural attachment was closed. Histopathological examination confirmed the diagnosis. Postoperatively, the child had unchanged, intact neurological function in both lower limbs. Almost all rachipagus parasitic twins are associated with spinal malformations. They should, therefore, be operated on by surgeons experienced in myelomeningocele surgery.

    In modern Minimally Invasive Spine Surgery (MISS), lack of visualization and haptic feedback information are the main obstacles. The spinal cord is a part of the central nervous system (CNS). It is a continuation of the brain stem, carries motor and sensory messages between CNS and the rest of body, and mediates numerous spinal reflexes. Spinal cord and spinal nerves are of great importance but vulnerable, once injured it may result in severe consequences to patients, e.g. paralysis. Raman Spectroscopy has been proved to be an effective and powerful tool in biological and biomedical applications as it works in a rapid, non-invasive and label-free way. It can provide molecular vibrational features of tissue samples and reflect content and proportion of protein, nucleic acids lipids etc. Due to the distinct chemical compositions spinal nerves have, we proposed that spinal nerves can be identified from other types of tissues by using Raman spectroscopy. Ex vivo experiments were first done on samples taken from swine backbones. Comparative spectral data of swine spinal cord, spinal nerves and adjacent tissues (i.e. membrane layer of the spinal cord, muscle, bone and fatty tissue) are obtained by a Raman micro-spectroscopic system and the peak assignment is done. Then the average spectra of all categories of samples are averaged and normalized to the same scale to see the difference against each other. The results verified the feasibility of spinal cord and spinal nerves identification by using Raman spectroscopy. Besides, a fiber-optic Raman sensing system including a miniature Raman sensor for future study is also introduced. This Raman sensor can be embedded into surgical tools for MISS.

    Full Text Available Background: Although adhesive arachnoiditis of the spinal cord can cause progressive symptoms associated with syringomyelia or myelomalacia, its surgical resolution based on the imaging diagnosis is not well characterized. This study aims to describe the use of imaging for the diagnosis of focal adhesive arachnoiditis of the spinal cord and its surgical resolution using microsurgical arachnoidolysis. Materials and Methods: Four consecutive patients with symptomatic syringomyelia or myelomalacia caused by focal adhesive arachnoiditis underwent microsurgical arachnoidolysis. Comprehensive imaging evaluation using constructive interference in steady-state (CISS magnetic resonance imaging (MRI or myelographic MR imaging using true fast imaging with steady-state precession (TrueFISP sequences was included before surgery to determine the surgical indication. Results: In all four patients a focal adhesion was identified at the cervical or thoracic level of the spinal cord, a consequence of infection or trauma. Three patients showed modest or minor improvement in neurological function, and one patient was unchanged after surgery. The syringomyelia or myelomalacia resolved after surgery and no recurrence was noted within the follow-up period, which ranged from 5 months to 30 months. Conclusions: MRI diagnosis of focal adhesive arachnoiditis is critical to determine the surgical indication. Microsurgical arachnoidolysis appears to be a straightforward method for stabilizing the progressive symptoms, though the procedure is technically demanding.

    Background and purpose - Routine outcome measurement has been shown to improve performance in several fields of healthcare. National spine surgery registries have been initiated in 5 Nordic countries. However, there is no agreement on which outcomes are essential to measure for adolescent and young adult patients with a spinal deformity. The aim of this study was to develop a core outcome set (COS) that will facilitate benchmarking within and between the 5 countries of the Nordic Spinal Deformity Society (NSDS) and other registries worldwide. Material and methods - From August 2015 to September 2016, 7 representatives (panelists) of the national spinal surgery registries from each of the NSDS countries participated in a modified Delphi study. With a systematic literature review as a basis and the International Classification of Functioning, Disability and Health framework as guidance, 4 consensus rounds were held. Consensus was defined as agreement between at least 5 of the 7 representatives. Data were analyzed qualitatively and quantitatively. Results - Consensus was reached on the inclusion of 13 core outcome domains: "satisfaction with overall outcome of surgery", "satisfaction with cosmetic result of surgery", "pain interference", physical functioning", "health-related quality of life", "recreation and leisure", "pulmonary fatigue", "change in deformity", "self-image", "pain intensity", "physical function", "complications", and "re-operation". Panelists agreed that the SRS-22r, EQ-5D, and a pulmonary fatigue questionnaire (yet to be developed) are the most appropriate set of patient-reported measurement instruments that cover these outcome domains. Interpretation - We have identified a COS for a large subgroup of spinal deformity patients for implementation and validation in the NSDS countries. This is the first study to further develop a COS in a global perspective.

    Full Text Available Postoperative pneumonia (POP is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC surgery.Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016. We individually traced each OC patient for a period to discharge from the hospital or 45 days after surgery, whichever occur later.The incidence of POP after major OC surgery with free flap construction or major OC surgery was 11.6% or 4.5%, respectively. Patient-related risk factors for POP were male sex, T stage, N stage, clinical stage and preoperative serum albumin level. Among the investigated procedure-related variables, incision grade, mandibulectomy, free flap reconstruction, tracheotomy, intraoperative blood loss, and the length of the operation were shown to be associated with the development of POP. Postoperative hospital stay was also significantly related to increased incidence of POP. Using a multivariable logistic regression model, we identified male sex, preoperative serum albumin level, operation time and postoperative hospital stay as independent risk factors for POP.Several perioperative risk factors can be identified that are associated with POP. At-risk oral cancer patients should be subjected to intensified postoperative pulmonary care.

    Full Text Available Background. The study of the influence of various factors on the course of recovery of neurological disorders in children with spinal cord injuries is an important and relevant problem. The main causes of thoracic and lumbar injuries of the spine in children are road accidents and catatraumas. Anatomical and physiological features of the spine and spinal cord in children have a significant influence on the nature of spinal cord injury, clinical manifestations of the injury, and method of treatment. The degree of spinal canal deformity at the level of the damaged segment is directly proportional to the severity of the neurological disorder. The time between injury to when surgery is performed will strongly influence the nature and course of recovery of motor functions. Aim. To assess the influence of different factors in pediatric patients with complicated injuries of the spine at the thoracic and thoracolumbar levels on the recovery of neurological disorders. Materials and methods. The analysis of results of the surgical treatment of 36 children (24 boys and 12 girls aged 3-17 years with damage to the spine and spinal cord in the thoracic spine and thoracolumbar junction, accompanied with neurological deficit in the form of central or peripheral paresis and paralysis, was performed. All patients underwent surgical intervention depending on the type and extent of damage. Clinical methods (i.e., detailed neurological examination as well as X-ray, CT, and MRI were used as diagnostic methods. Results. The study revealed that the most severe damage concerning neurological disorders in children with spinal cord injury occurs in the thoracic spine. The extent of neurological changes depends not only on the level of damage to the spinal column but also on the magnitude of spinal canal stenosis. Surgery performed in the first hours of the injury leads to a more rapid and full recovery of the neurological deficit. Conclusion. Therefore, this study found

  5. The Lesioned Spinal Cord Is a “New” Spinal Cord: Evidence from Functional Changes after Spinal Injury in Lamprey

    2017-01-01

    Finding a treatment for spinal cord injury (SCI) focuses on reconnecting the spinal cord by promoting regeneration across the lesion site. However, while regeneration is necessary for recovery, on its own it may not be sufficient. This presumably reflects the requirement for regenerated inputs to interact appropriately with the spinal cord, making sub-lesion network properties an additional influence on recovery. This review summarizes work we have done in the lamprey, a model system for SCI research. We have compared locomotor behavior (swimming) and the properties of descending inputs, locomotor networks, and sensory inputs in unlesioned animals and animals that have received complete spinal cord lesions. In the majority (∼90%) of animals swimming parameters after lesioning recovered to match those in unlesioned animals. Synaptic inputs from individual regenerated axons also matched the properties in unlesioned animals, although this was associated with changes in release parameters. This suggests against any compensation at these synapses for the reduced descending drive that will occur given that regeneration is always incomplete. Compensation instead seems to occur through diverse changes in cellular and synaptic properties in locomotor networks and proprioceptive systems below, but also above, the lesion site. Recovery of locomotor performance is thus not simply the reconnection of the two sides of the spinal cord, but reflects a distributed and varied range of spinal cord changes. While locomotor network changes are insufficient on their own for recovery, they may facilitate locomotor outputs by compensating for the reduction in descending drive. Potentiated sensory feedback may in turn be a necessary adaptation that monitors and adjusts the output from the “new” locomotor network. Rather than a single aspect, changes in different components of the motor system and their interactions may be needed after SCI. If these are general features, and where

    This study evaluates the effect of prophylactic granisetron on the incidence of postoperative shivering after spinal anaesthesia in children. Eighty children, American Society of Anesthesiologists physical status I to II and aged two to five years were scheduled for surgery of the lower limb under spinal anaesthesia. The children were randomised to receive 10 µg/kg granisetron diluted in 10 ml saline 0.9% intravenously (group 1, n=40) or placebo (10 ml 0.9% saline, group 2, n=40) to be given over five minutes just before spinal puncture. Shivering, core temperature and the levels of motor and sensory block were assessed. No patients shivered in group 1. However, six patients shivered in Group 2 (P=0.025). There were no significant differences in the other measured variables between the groups. Granisetron is an effective agent to prevent shivering after spinal anaesthesia in children from two to five years of age.

    Background. Magnetic resonance imaging (MRI) is the recommended primary investigation method for metastatic spinal cord compression (MSCC). Initiating treatment before the development of motor deficits is essential to preserve neurological function. However, the relationship between MRI-assessed grades of spinal metastatic disease and neurological status has not been widely investigated. Purpose. To analyze the association between neurological function and MRI-based assessment of the extent of spinal metastases using two different grading systems. Material and Methods. A total of 284 patients admitted to our institution for initial radiotherapy or surgery for symptomatic spinal metastases were included in the study. Motor and sensory deficits were categorized according to the Frankel classification system. Pre-treatment MRI evaluations of the entire spine were scored for the extent of spinal metastases, presence and severity of spinal cord compression, and nerve root compression. Two MRI-based scales were used to evaluate the degree of cord compression and spinal canal narrowing and relate these findings to neurological function. Results. Of the patients included in the study, 28 were non-ambulatory, 49 were ambulatory with minor motor deficits, and 207 had normal motor function. Spinal cord compression was present in all patients with Frankel scores of B or C, 23 of 35 patients with a Frankel score of D (66%), and 48 of 152 patients with a Frankel score of E (32%). The percentage of patients with severe spinal canal narrowing increased with increasing Frankel grades. The grading according to the scales showed a significant association with the symptoms according to the Frankel scale (P < 0.001). Conclusion. In patients with neurological dysfunction, the presence and severity of impairment was associated with the epidural tumor burden. A significant number of patients had radiological spinal cord compression and normal motor function (occult MSCC)

    Full Text Available Spinal muscular atrophy (SMA is a major genetic cause of death in childhood characterized by marked muscle weakness. To investigate mechanisms underlying motor impairment in SMA, we examined the spinal and neuromuscular circuitry governing hindlimb ambulatory behavior in SMA model mice (SMNΔ7. In the neuromuscular circuitry, we found that nearly all neuromuscular junctions (NMJs in hindlimb muscles of SMNΔ7 mice remained fully innervated at the disease end stage and were capable of eliciting muscle contraction, despite a modest reduction in quantal content. In the spinal circuitry, we observed a ∼28% loss of synapses onto spinal motoneurons in the lateral column of lumbar segments 3-5, and a significant reduction in proprioceptive sensory neurons, which may contribute to the 50% reduction in vesicular glutamate transporter 1(VGLUT1-positive synapses onto SMNΔ7 motoneurons. In addition, there was an increase in the association of activated microglia with SMNΔ7 motoneurons. Together, our results present a novel concept that synaptic defects occur at multiple levels of the spinal and neuromuscular circuitry in SMNΔ7 mice, and that proprioceptive spinal synapses could be a potential target for SMA therapy.

    Indications for surgery for symptomatic spinal metastases have become better defined in recent years, and suitable outcome measures have been established against a changing backdrop of patient characteristics, tumor behavior, and oncologic treatments. Nonetheless, variations still exist in the local management of patients with spinal metastases. In this study, we aimed to review global trends and habits in the surgical treatment of symptomatic spinal metastases, and to examine how these have changed over the last 25 years. In this cohort study of consecutive patients undergoing surgery for symptomatic spinal metastases, data were collected using a secure Internet database from 22 centers across 3 continents. All patients were invited to participate in the study, except those unable or unwilling to give consent. There was a higher incidence of colonic, liver, and lung carcinoma metastases in Asian countries, and more frequent presentation of breast, prostate, melanoma metastases in the West. Trends in surgical technique were broadly similar across the centers. Overall survival rates after surgery were 53% at 1 year, 31% at 2 years, and 10% at 5 years after surgery (standard error 0.013 for all). Survival improved over successive time periods, with longer survival in patients who underwent surgery in 2011-2016 compared with those who underwent surgery in earlier time periods. Surgical habits have been fairly consistent among countries worldwide and over time. However, patient survival has improved in later years, perhaps due to medical advances in the treatment of cancer, improved patient selection, and operating earlier in the course of disease.

    Full Text Available Spinal metastasis of differentiated thyroid cancer can have a favorable prognosis if radical surgery is performed. We encountered a case of spinal metastasis involving three anterior vertebral bodies at the posterior element fusion level and successfully achieved adequate stability by radical surgery involving only the anterior elements. A 67-year-old woman who had numbness and muscle weakness in the lower limbs caused by metastatic spinal tumor at the posterior element fusion level of L1–L3 vertebrae was treated with radical surgery of only the anterior element to gain stability. Similar situations may occur in cases involving other malignant tumor metastases or spinal primary tumors. If such a case occurs, this method could be useful in preventing metastasis to the posterior element.

    Major surgery as well as endotoxin-induced sepsis is accompanied by lymphocytopenia in peripheral blood. The purpose of this study was to investigate the redistribution of lymphocyte subpopulations and adhesion/activation molecules on lymphocytes.

    Thirty-four patients with intramedullary space-occupying lesions or cord compression syndromes were examined with a resistive and two different superconductive magnetic resonance (MR) imaging units. Studies were done primarily by the spin-echo (SE) technique and in the majority of patients different pulse sequences were used. Images with short echo-time (TE) and short recovery-time (TR) were best for demonstration of spinal cord anatomy, for depicting cystic portions in intramedullary tumours and for showing syringomyelia. Solid intramedullary tumours showed normal cord signal intensity. Images with prolonged TE and TR predominantly enhanced CSF signal intensity and, to a more considerable extent, solid intramedullary tumours. Thus, the diameter of the subarachnoid space and the presence of a solid intramedullary tumour, not concomittant with a significant enlargement of the spinal cord, could only be recognized on these prolonged SE images. Major advantages of MR in comparison to CT are that the spinal cord can be imaged in the sagittal plane and that beam hardening artifacts do not occur; in comparison to myelography the cord can be imaged directly by MR. Partial volume is a major limitation of MR, not only in the preferably applied sagittal plane. The choice of slice thickness adequate to the diameter of the lesion and straight positioning of the patient for sagittal single slice midline images are fundamental for reliable MR investigations. Another limitation to MR is that cortical bone gives no signal. The actual diameter of the spinal canal therefore cannot be correctly appreciated and consequently it was difficult or impossible to assess spinal stenosis. (orig.)

    Antibiotics are always considered for surgical site infection (SSI) in adolescent idiopathic scoliosis (AIS) surgery. However, the use of antibiotics often causes the antibiotic resistance of pathogens and side effects. Thus, it is necessary to explore natural products as drug candidates. Chitin Oligosaccharide (COS) has anti-inflammation and anti-bacteria functions. The effects of COS on surgical infection in AIS surgery were investigated. A total of 312 AIS patients were evenly and randomly assigned into control group (CG, each patient took one-gram alternative Azithromycin/Erythromycin/Cloxacillin/Aztreonam/Ceftazidime or combined daily), experiment group (EG, each patient took 20 mg COS and half-dose antibiotics daily), and placebo group (PG, each patient took 20 mg placebo and half-dose antibiotics daily). The average follow-up was one month, and infection severity and side effects were analyzed. The effects of COS on isolated pathogens were analyzed. SSI rates were 2%, 3% and 8% for spine wounds and 1%, 2% and 7% for iliac wound in CG, EG and PG ( p antibiotics ( p antibiotics dose and antibiotics-caused side effects in AIS patients with spinal fusion surgery by improving antioxidant and anti-inflammatory activities. COS should be developed as potential adjuvant for antibiotics therapies.

    Surgical management of patients with multilevel CSM aims to decompress the spinal cord and restore the normal sagittal alignment. The literature lacks of high level evidences about the best surgical approach. Posterior decompression and stabilization in lordosis allows spinal cord back shift, leading to indirect decompression of the anterior spinal cord. The purpose of this study was to investigate the efficacy of posterior decompression and stabilization in lordosis for multilevel CSM. 36 out of 40 patients were clinically assessed at a mean follow-up of 5, 7 years. Outcome measures included EMS, mJOA Score, NDI and SF-12. Patients were asked whether surgery met their expectations and if they would undergo the same surgery again. Bone graft fusion, instrumental failure and cervical curvature were evaluated. Spinal cord back shift was measured and correlation with EMS and mJOA score recovery rate was analyzed. All scores showed a significative improvement (p 0.05). Ninety percent of patients would undergo the same surgery again. There was no deterioration of the cervical alignment, posterior grafted bones had completely fused and there were no instrument failures. The mean spinal cord back shift was 3.9 mm (range 2.5-4.5 mm). EMS and mJOA recovery rates were significantly correlated with the postoperative posterior cord migration (P lordosis is a valuable procedure for patients affected by multilevel CSM, leading to significant clinical improvement thanks to the spinal cord back shift. Postoperative lordotic alignment of the cervical spine is a key factor for successful treatment.

    Many orthopedic articles describe advances in surgical techniques and implants used in pediatric scoliosis surgery. However, even though postoperative spine imaging constitutes a large portion of outpatient musculoskeletal pediatric radiology, few, if any, radiology articles discuss this topic. There has been interval advancement over the last decades of the orthopedic procedures used in the treatment of spinal scoliosis in adolescents with idiopathic scoliosis. The goal of treatment in these patients is to stop the progression of the curve by blocking the spinal growth and correcting the deformity as much as possible. To that end, the authors in this paper discuss postoperative imaging findings of Harrington rods, Luque rods, Luque-Galveston implants and segmental spinal fusion systems. Regarding early onset scoliosis, the guiding principles used for adolescent idiopathic scoliosis do not apply to a growing spine because they would impede lung development. As a result, other devices have been developed to correct the curve and to allow spinal growth. These include spine-based growing rods, vertically expandable prosthetic titanium rods (requiring repetitive surgeries) and magnetically controlled growing rods (with a magnetic locking/unlocking system). Other more recent systems are Shilla and thoracoscopic anterior vertebral body tethering, which allow guided growth of the spine without repetitive interventions. In this paper, we review the radiologic appearances of different orthopedic implants and techniques used to treat adolescent idiopathic scoliosis and early onset scoliosis. Moreover, we present the imaging findings of the most frequent postoperative complications. (orig.)

    Spinal disorders, particularly low back pain, are among the most common reasons for general practitioner (GP) consultation and can sometimes be a source of professional friction. Despite their frequency and published guidelines, many patients are still mistakenly referred by their GP to specialists for spinal surgery consultation which can create colleague relationship problems, suboptimal or unnessary delayed care, as well as the financial implications for patients. To assess the management of GP lumbar spine referrals made to 4 neurosurgeons from 3 neurosurgical teams specialized in spinal surgery. All patient's medical records relating to 672 primary consultants over a period of two months (January and February 2015) at three institutions were retrospectively reviewed. Medical referral letters, clinical evidence and imaging data were analyzed and the patients were classified according the accuracy of surgical assessment. The final decisions of the surgeons were also considered. Of the 672 patients analyzed, 198 (29.5%) were considered unsuitable for surgical assessment: no spinal pathology=10.6%, no surgical conditions=35.4%, suboptimal medical treatment=31.3%, suboptimal radiology=18.2% and asymptomatic patients=4.5%. Unnecessary referrals to our consultation centers highlight the gap between the reason for the consultation and the indications for spinal surgery. Compliance with the guidelines, the creation of effective multidisciplinary teams, as well as the "hands on" involvement of surgeons in primary and continuing education of physicians are the best basis for a reduction in inappropriate referrals and effective patient care management.

    Ischemic tolerance is an endogenous neuroprotective phenomenon induced by sublethal ischemia. Ischemic preconditioning (IPC), the first discovered form of ischemic tolerance, is widely seen in many species and in various organs including the brain and the spinal cord. Ischemic tolerance of the spinal cord is less familiar among neurosurgeons, although it has been reported from the viewpoint of preventing ischemic spinal cord injury during aortic surgery. It is important for neurosurgeons to have opportunities to see patients with spinal cord ischemia, and to understand ischemic tolerance of the spinal cord as well as the brain. IPC has a strong neuroprotective effect in animal models of ischemia; however, clinical application of IPC for ischemic brain and spinal diseases is difficult because they cannot be predicted. In addition, one drawback of preconditioning stimuli is that they are also capable of producing injury with only minor changes to their intensity or duration. Numerous methods to induce ischemic tolerance have been discovered that vary in their timing and the site at which short-term ischemia occurs. These methods include ischemic postconditioning (IPoC), remote ischemic preconditioning (RIPC), remote ischemic perconditioning (RIPerC) and remote ischemic postconditioning (RIPoC), which has had a great impact on clinical approaches to treatment of ischemic brain and spinal cord injury. Especially RIPerC and RIPoC to induce spinal cord tolerance are considered clinically useful, however the evidence supporting these methods is currently insufficient; further experimental or clinical research in this area is thus necessary.

    Full Text Available Spinal cord injury is a major trauma, with its short and long term effects and consequences to the patient, his friends and family. Spinal cord injury is addressed in the developed countries with standard trauma care system commencing immediately after injury and continuing to the specialized rehabilitation units. Rehabilitation is important to those with spinal injury for both functional and psychosocial reintegration. It has been an emerging concept in Nepal, which has been evident with the establishment of the various hospitals with rehabilitation units, rehabilitation centres and physical therapy units in different institutions. However, the spinal cord injury rehabilitation setting and scenario is different in Nepal from those in the developed countries since spinal cord injury rehabilitation care has not been adequately incorporated into the health care delivery system nor its importance has been realized within the medical community of Nepal. To name few, lack of human resource for the rehabilitation care, awareness among the medical personnel and general population, adequate scientific research evidence regarding situation of spinal injury and exorbitant health care policy are the important hurdles that has led to the current situation. Hence, it is our responsibility to address these apparent barriers to successful implementation and functioning of rehabilitation so that those with spinal injury would benefit from enhanced quality of life. Keywords: rehabilitation; spinal injury.

    Paraplegia secondary to spinal cord ischemia-reperfusion injury remains a devastating complication of thoracoabdominal aortic intervention. The complex interactions between injured neurons and activated leukocytes have limited the understanding of neuron-specific injury. We hypothesize that spinal cord neuron cell cultures subjected to oxygen-glucose deprivation (OGD) would simulate ischemia-reperfusion injury, which could be attenuated by specific alpha-2a agonism in an Akt-dependent fashion. Spinal cords from perinatal mice were harvested, and neurons cultured in vitro for 7-10 d. Cells were pretreated with 1 μM dexmedetomidine (Dex) and subjected to OGD in an anoxic chamber. Viability was determined by MTT assay. Deoxyuridine-triphosphate nick-end labeling staining and lactate dehydrogenase (LDH) assay were used for apoptosis and necrosis identification, respectively. Western blot was used for protein analysis. Vehicle control cells were only 59% viable after 1 h of OGD. Pretreatment with Dex significantly preserves neuronal viability with 88% viable (P control cells by 50% (P neuron cell culture, OGD mimics neuronal metabolic derangement responsible for paraplegia after aortic surgery.

    Major upper abdominal surgery is often associated with reduced health-related quality of life and reduced survival. Patients with upper abdominal malignancies often suffer from cachexia, represented by preoperative weight loss and sarcopenia (low skeletal muscle mass) and this might affect both health-related quality of life and survival. We aimed to investigate how health-related quality of life is affected by cachexia and how health-related quality of life relates to long-term survival after major upper abdominal surgery. From 2001 to 2006, 447 patients were included in a Norwegian multicenter randomized controlled trial in major upper abdominal surgery. In this study, six years later, these patients were analyzed as a single prospective cohort and survival data were retrieved from the National Population Registry. Cachexia was derived from patient-reported preoperative weight loss and sarcopenia as assessed from computed tomography images taken within three months preoperatively. In the original trial, self-reported health-related quality of life was assessed preoperatively at trial enrollment and eight weeks postoperatively with the health-related quality of life questionnaire Short Form 36. A majority of the patients experienced improved mental health-related quality of life and, to a lesser extent, deteriorated physical health-related quality of life following surgery. There was a significant association between preoperative weight loss and reduced physical health-related quality of life. No association between sarcopenia and health-related quality of life was observed. Overall survival was significantly associated with physical health-related quality of life both pre- and postoperatively, and with postoperative mental health-related quality of life. The association between health-related quality of life and survival was particularly strong for postoperative physical health-related quality of life.

    Orthopedics and trauma surgery are subject to continuous medical advancement. The correct and performance-based case allocation by German diagnosis-related groups (G-DRG) is a major challenge. This article analyzes and assesses current developments in orthopedics and trauma surgery in the areas of coding of diagnoses and medical procedures and the development of the 2012 G-DRG system. The relevant diagnoses, medical procedures and G-DRGs in the versions 2011 and 2012 were analyzed based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Changes were made for the International Classification of Diseases (ICD) coding of complex cases with medical complications, the procedure coding for spinal surgery and for hand and foot surgery. The G-DRG structures were modified for endoprosthetic surgery on ankle, shoulder and elbow joints. The definition of modular structured endoprostheses was clarified. The G-DRG system for orthopedic and trauma surgery appears to be largely consolidated. The current phase of the evolution of the G-DRG system is primarily aimed at developing most exact descriptions and definitions of the content and mutual delimitation of operation and procedures coding (OPS). This is an essential prerequisite for a correct and performance-based case allocation in the G-DRG system.

    Full Text Available Abstract Background Approximately 70,000 patients/year undergo surgery for repair of a fractured hip in the United Kingdom. This is associated with 30-day mortality of 9% and survivors have a considerable length of acute hospital stay postoperatively (median 26 days. Use of oesophageal Doppler monitoring to guide intra-operative fluid administration in hip fracture repair has previously been associated with a reduction in hospital stay of 4-5 days. Most hip fracture surgery is now performed under spinal anaesthesia. Oesophageal Doppler monitoring may be unreliable in the presence of spinal anaesthesia and most patients would not tolerate the probes. An alternative method of guiding fluid administration (minimally-invasive arterial pulse contour analysis has been shown to reduce length of stay in high-risk surgical patients but has never been studied in hip fracture surgery. Methods Single-centre randomised controlled parallel group trial. Randomisation by website using computer generated concealed tables. Setting: University hospital in UK. Participants: 128 patients with acute primary hip fracture listed for operative repair under spinal anaesthesia and aged > 65 years. Intervention: Stroke volume guided intra-operative fluid management. Continuous measurement of SV recorded by a calibrated cardiac output monitor (LiDCOplus. Maintenance fluid and 250 ml colloid boluses given to achieve sustained 10% increases in stroke volume. Control group: fluid administration at the responsible (blinded anaesthetist's discretion. The intervention terminates at the end of the surgical procedure and post-operative fluid management is at the responsible anaesthetist's discretion. Primary outcome: length of acute hospital stay is determined by a blinded team of clinicians. Secondary outcomes include number of complications and total cost of care.

    With an increasing ability to diagnose and treat the neurological complications, surveillance of the state of the spinal cord has now assumed great importance. Magnetic resonance imaging (MRI), or computerized tomography (CT) with myelography if MRI is contra-indicated is the method of choice and can demonstrate the pathology with great clarity. In most patients, midline sagittal T1W images are sufficient for screening purposes and for monitoring the success of treatment. Operative, imaging and postmortem studies have shown that the two main changes that occur are: (a) atrophic and (b) cystic - the microcystic and myxoid gel changes of myelomalacia, focal cysts and the larger, more expansive, syringomyelia. As yet, there is no standardization of terminology to describe the various pathological and radiological states. This is critical as only one condition, syringomyelia, is currently amenable to definitive surgery and without conformity, comparisons of incidence in different populations and assessment of the results of surgery are impossible. The published small studies of predominantly symptomatic patients at varying stages of chronicity give differing incidences of changes. Preliminary results of a surveillance MRI study of the spinal cord changes in 153 patients who had had a spinal cord injury over 20 years previously are presented. Altrophy was present in 62%, myelomalacia in 54%, syringomyelia in 22%, focal cysts in 9% and disruption in 7%. (orig./VHE) [de

    Dramatic increases in the average life expectancy have led to increases in the variety of degenerative changes and deformities observed in the aging spine. The elderly population can present challenges for spine surgeons, not only because of increased comorbidities, but also because of the quality of their bones. Pedicle screws are the implants used most commonly in spinal surgery for fixation, but their efficacy depends directly on bone quality. Although polymethyl methacrylate (PMMA)-augmented screws represent an alternative for patients with osteoporotic vertebrae, their use has raised some concerns because of the possible association between cement leakages (CLs) and other morbidities. To analyze potential complications related to the use of cement-augmented screws for spinal fusion and to investigate the effectiveness of using these screws in the treatment of patients with low bone quality. A retrospective single-center study. This study included 313 consecutive patients who underwent spinal fusion using a total of 1,780 cement-augmented screws. We analyzed potential complications related to the use of cement-augmented screws, including CL, vascular injury, infection, screw extraction problems, revision surgery, and instrument failure. There are no financial conflicts of interest to report. A total of 1,043 vertebrae were instrumented. Cement leakage was observed in 650 vertebrae (62.3%). There were no major clinical complications related to CL, but two patients (0.6%) had radicular pain related to CL at the S1 foramina. Of the 13 patients (4.1%) who developed deep infections requiring surgical debridement, two with chronic infections had possible spondylitis that required instrument removal. All patients responded well to antibiotic therapy. Revision surgery was performed in 56 patients (17.9%), most of whom had long construction. A total of 180 screws were removed as a result of revision. There were no problems with screw extraction. These results

    2008-08-01

    Full Text Available Abstract Background Spinal fusion surgery is currently recommended when curve magnitude exceeds 40–45 degrees. Early attempts at spinal fusion surgery which were aimed to leave the patients with a mild residual deformity, failed to meet such expectations. These aims have since been revised to the more modest goals of preventing progression, restoring 'acceptability' of the clinical deformity and reducing curvature. In view of the fact that there is no evidence that health related signs and symptoms of scoliosis can be altered by spinal fusion in the long-term, a clear medical indication for this treatment cannot be derived. Knowledge concerning the rate of complications of scoliosis surgery may enable us to establish a cost/benefit relation of this intervention and to improve the standard of the information and advice given to patients. It is also hoped that this study will help to answer questions in relation to the limiting choice between the risks of surgery and the "wait and see – observation only until surgery might be recommended", strategy widely used. The purpose of this review is to present the actual data available on the rate of complications in scoliosis surgery. Materials and methods Search strategy for identification of studies; Pub Med and the SOSORT scoliosis library, limited to English language and bibliographies of all reviewed articles. The search strategy included the terms; 'scoliosis'; 'rate of complications'; 'spine surgery'; 'scoliosis surgery'; 'spondylodesis'; 'spinal instrumentation' and 'spine fusion'. Results The electronic search carried out on the 1st February 2008 with the key words "scoliosis", "surgery", "complications" revealed 2590 titles, which not necessarily attributed to our quest for the term "rate of complications". 287 titles were found when the term "rate of complications" was used as a key word. Rates of complication varied between 0 and 89% depending on the aetiology of the entity investigated

    Full Text Available Background. Malnutrition has serious implications for recovery after surgery. Early detection of malnutrition with nutritional support minimizes postoperative complications. Nutritional assessment tools need to be simple and suitable for use in everyday practice. In our study we wanted to determine, how many patients might benefit from nutritional support.Methods. From April to August 1999 fifty consecutively admitted patients predicted to major abdominal surgery have been examined. We used Mini nutritional assessment (MNA, Buzby’s nutrition risk index (NRI, blood albumin level and weight loss in the last 3 months period prior to the examination, to assess nutritional status.Results. We examined 50 patients (27 males and 23 females, age 76.5 ± 16.5 and confirmed malnutrition in 40% of patients with MNA and serum albumin level. The increased risk for nutrition-associated complications was confirmed by NRI and weight loss in 44%.Conclusions. A confident diagnosis of malnutrition and increased risk for nutrition-associated complications can be established by using a combination of simple methods like MNA, NRI, weight loss and serum albumin level. Almost half of the patients admitted for major abdominal surgery in General hospital Celje suffer from malnutrition and they may benefit with early nutritional intervention.

    The authors report a case of functional improvement of the paralyzed diaphragm in high cervical quadriplegia via phrenic nerve neurotization using a functional spinal accessory nerve. Complete spinal cord injury at the C-2 level was diagnosed in a 44-year-old man. Left diaphragm activity was decreased, and the right diaphragm was completely paralyzed. When the level of metabolism or activity (for example, fever, sitting, or speech) slightly increased, dyspnea occurred. The patient underwent neurotization of the right phrenic nerve with the trapezius branch of the right spinal accessory nerve at 11 months postinjury. Four weeks after surgery, training of the synchronous activities of the trapezius muscle and inspiration was conducted. Six months after surgery, motion was observed in the previously paralyzed right diaphragm. The lung function evaluation indicated improvements in vital capacity and tidal volume. This patient was able to sit in a wheelchair and conduct outdoor activities without assisted ventilation 12 months after surgery.

    Early mobilization after major abdominal surgery decreases postoperative complications and length of stay, and has become a key component of enhanced recovery pathways. However, objective measures of patient movement after surgery are limited. Real-time location systems (RTLS), typically used for asset tracking, provide a novel approach to monitoring in-hospital patient activity. The current study investigates the feasibility of using RTLS to objectively track postoperative patient mobilization. The real-time location system employs a meshed network of infrared and RFID sensors and detectors that sample device locations every 3 s resulting in over 1 million data points per day. RTLS tracking was evaluated systematically in three phases: (1) sensitivity and specificity of the tracking device using simulated patient scenarios, (2) retrospective passive movement analysis of patient-linked equipment, and (3) prospective observational analysis of a patient-attached tracking device. RTLS tracking detected a simulated movement out of a room with sensitivity of 91% and specificity 100%. Specificity decreased to 75% if time out of room was less than 3 min. All RTLS-tagged patient-linked equipment was identified for 18 patients, but measurable patient movement associated with equipment was detected for only 2 patients (11%) with 1-8 out-of-room walks per day. Ten patients were prospectively monitored using RTLS badges following major abdominal surgery. Patient movement was recorded using patient diaries, direct observation, and an accelerometer. Sensitivity and specificity of RTLS patient tracking were both 100% in detecting out-of-room ambulation and correlated well with direct observation and patient-reported ambulation. Real-time location systems are a novel technology capable of objectively and accurately monitoring patient movement and provide an innovative approach to promoting early mobilization after surgery.

    Full Text Available Objective: Regional anesthesia is preferred more than general anesthesia in major lower extremity surgery. In our study, we aimed to investigate the relationship incidence of complications between regional anesthesia and general anesthesia in major surgery. Method: A total of 372 patients who underwent total hip or knee replacement from 1 January 2009 to 31 December 2012 were evaluated retrospectively in the study. The number of patients undergoing general anesthesia and regional anesthesia was respectively 118 and 254. If the patient has a history of more than one hip or knee replacements we were included only the first operation in the study. Postoperative complications were investigated over the course of 30 days. Patients' age, sex, type of operation (unilateral, bilateral, whether additional disease, postoperative complications were evaluated. Results: There were no difference for patients' age, sex and in terms of additional diseases. 92 patients general anesthesia and 135 patients regional anesthesia were performed to the patients who underwent total hip replacement, and 26 general anesthesia and 119 regional anesthesia is applied to patients who underwent total knee replacement (p=0.001. Postoperative complications are examined none of patients had no cardiac attack. Pulmonary embolism and death were found 7 in general anesthesia and 2 in regional anesthesia. Surgical site infection was found in 9 patients undergoing general anesthesia and 7 patients undergoing regional anesthesia and difference was statistically significant. Conclusion: In our clinic, regional and general anesthesia in patients undergoing major lower limb surgery applications observe significant difference in terms of complications during the postoperative period of 1 month.

    Navigation technology is used for training in various medical specialties, not least image-guided spinal interventions. Navigation practice is an important educational component that allows residents to understand how surgical instruments interact with complex anatomy and to learn basic surgical skills such as the tridimensional mental interpretation of bidimensional data. Inexpensive surgical simulators for spinal surgery, however, are lacking. We therefore designed a low-cost spinal surgery simulator (Spine MovDigSys 01) to allow 3-dimensional navigation via 2-dimensional images without altering or limiting the surgeon's natural movement. A training system was developed with an anatomical lumbar model and 2 webcams to passively digitize surgical instruments under MATLAB software control. A proof-of-concept recognition task (vertebral body cannulation) and a pilot test of the system with 12 neuro- and orthopedic surgeons were performed to obtain feedback on the system. Position, orientation, and kinematic variables were determined and the lateral, posteroanterior, and anteroposterior views obtained. The system was tested with a proof-of-concept experimental task. Operator metrics including time of execution (t), intracorporeal length (d), insertion angle (α), average speed (v¯), and acceleration (a) were obtained accurately. These metrics were converted into assessment metrics such as smoothness of operation and linearity of insertion. Results from initial testing are shown and the system advantages and disadvantages described. This low-cost spinal surgery training system digitized the position and orientation of the instruments and allowed image-guided navigation, the generation of metrics, and graphic recording of the instrumental route. Spine MovDigSys 01 is useful for development of basic, noninnate skills and allows the novice apprentice to quickly and economically move beyond the basics. Copyright © 2016 Elsevier Inc.

    Although sagittal spinal balance plays an important role in spinal deformity surgery, its role in decompression surgery for lumbar canal stenosis is not well understood. To investigate the hypothesis that sagittal spinal balance also plays a role in decompression surgery for lumbar canal stenosis, a prospective cohort study analyzing the correlation between preoperative lumbar lordosis and outcome was performed. A cohort of 85 consecutive patients who underwent decompression for lumbar canal stenosis during the period 2007-2011 was analyzed. Standing lumbar x-rays and 36-item short form health survey questionnaires were obtained before and up to 2 years after surgery. Correlations between lumbar lordosis and 2 parameters of the 36-item short form health survey (average physical score and bodily pain score) were statistically analyzed using linear mixed effects models. There was a significant correlation between preoperative lumbar lordosis and the 2 outcome parameters at postoperative, 6-month, 1-year, and 2-year time points. A 10° increase of lumbar lordosis was associated with a 5-point improvement in average physical scores. This correlation was not present in preoperative scores. This study showed that preoperative lumbar lordosis significantly influences the outcome of decompression surgery on lumbar canal stenosis. Copyright © 2017 Elsevier Inc. All rights reserved.

    2012-01-01

    The interpretation of spinal images fixed with metallic hardware forms an increasing bulk of daily practice in a busy imaging department. Radiologists are required to be familiar with the instrumentation and operative options used in spinal fixation and fusion procedures, especially in his or her institute. This is critical in evaluating the position of implants and potential complications associated with the operative approaches and spinal fixation devices used. Thus, the radiologist can play an important role in patient care and outcome. This review outlines the advantages and disadvantages of commonly used imaging methods and reports on the best yield for each modality and how to overcome the problematic issues associated with the presence of metallic hardware during imaging. Baseline radiographs are essential as they are the baseline point for evaluation of future studies should patients develop symptoms suggesting possible complications. They may justify further imaging workup with computed tomography, magnetic resonance and/or nuclear medicine studies as the evaluation of a patient with a spinal implant involves a multi-modality approach. This review describes imaging features of potential complications associated with spinal fusion surgery as well as the instrumentation used. This basic knowledge aims to help radiologists approach everyday practice in clinical imaging. PMID:22761979

    Full Text Available Introduction: Despite the vast number of surveys, no consensus has been reached on the optimum timing of spinal decompression surgery. This systematic review and meta-analysis aimed to compare the effects of early and late spinal decompression surgery on neurologic improvement and post-surgical complications in patients with traumatic spinal cord injuries.Methods: Two independent reviewers carried out an extended search in electronic databases. Data of neurological outcome and post-surgery complication were extracted. Finally, pooled relative risk (RR with a 95% confidence interval (CI was reported for comparing of efficacy of early and late surgical decompression.Results: Eventually 22 studies were included. The pooled RR was 0.77 (95% CI: 0.68-0.89 for at least one grade neurological improvement, and 0.84 (95% CI: 0.77-0.92 for at least two grade improvement. Pooled RR for surgical decompression performed within 12 hours after the injury was 0.26 (95% CI: 0.13-0.52; p<0.001, while it was 0.75 (95% CI: 0.63-0.90; p=0.002 when the procedure was performed within 24 hours, and 0.93 (95% CI: 0.76-1.14; p=0.48 when it was carried out in the first 72 hours after the injury. Surgical decompression performed within 24 hours after injury was found to be associated with significantly lower rates of post-surgical complications (RR=0.77; 95% CI: 0.68-0.86; p<0.001.Conclusion: The findings of this study indicate that early spinal decompression surgery can improve neurologic recovery and is associated with less post-surgical complications. The optimum efficacy is observed when the procedure is performed within 12 hours of the injury.

    The aim of this retrospective study was to evaluate the clinical outcome of patients with spinal dural arteriovenous fistulas (SDAVFs) that were treated with surgery, catheter embolization, or surgery after incomplete embolization. The study included 21 consecutive patients with SDAVFs of the thoracic, lumbar, or sacral spine who were treated in our institution from 1994 to 2007. Thirteen patients were treated with catheter embolization alone. Four patients underwent hemilaminectomy and intradural interruption of the fistula. Four patients were treated by endovascular techniques followed by surgery. The clinical outcome was assessed using the modified Aminoff-Logue scale (ALS) for myelopathy and the modified Rankin scale (MRS) for general quality of life. Patient age ranged from 44 to 77 years (mean 64.7 years). Surgical as well as endovascular treatment resulted in a significant improvement in ALS (-62.5% and -31.4%, respectively, p<0.05) and a tendency toward improved MRS (-50% and -32%, respectively) scores. Patients that underwent surgery after endovascular treatment due to incomplete occlusion of the fistula showed only a tendency for improvement in the ALS score (-16.7%), whereas the MRS score was not affected. We conclude that both endovascular and surgical treatment of SDAVFs resulted in a good and lasting clinical outcome in the majority of cases. In specific situations, when a secondary neurosurgical approach was required after endovascular treatment to achieve complete occlusion of the SDAVF, the clinical outcome was rather poor. The best first line treatment modality for each individual patient should be determined by an interdisciplinary team. (orig.)

    To assess the ability of the recently developed adult spinal deformity frailty index (ASD-FI) to predict odds of perioperative complications, odds of reoperation, and length of hospital stay after adult spinal deformity (ASD) surgery using a database other than the one used to create the index. We used the ASD-FI to calculate frailty scores for 266 ASD patients who had minimum postoperative follow-up of 2 years in the European Spine Study Group (ESSG) database. Patients were enrolled from 2012 through 2013. Using ASD-FI scores, we categorized patients as not frail (NF) ( 0.5 points). Multivariable logistic regression, adjusted for preoperative and surgical factors such as operative time and blood loss, was performed to determine the relationship between ASD-FI category and odds of major complications, odds of reoperation, and length of hospital stay. We categorized 135 patients (51%) as NF, 90 patients (34%) as frail, and 41 patients (15%) as SF. Overall mean ASD-FI score was 0.29 (range 0-0.8). The adjusted odds of experiencing a major intraoperative or postoperative complication (OR 4.5, 95% CI 2.0-10) or having a reoperation (OR 3.9, 95% CI 1.7-8.9) were higher for SF patients compared with NF patients. Mean hospital stay was 2.1 times longer (95% CI 1.8-2.4) for SF patients compared with NF patients. Greater patient frailty, as measured by the ASD-FI, is associated with longer hospital stays and greater odds of major complications and reoperation.

    Objectives The Korean Resource Based Relative Value Scale (K-RBRVS) was introduced in 2001 as an alternative of the previous medical fee schedule. Unfortunately, most neurosurgeons are unfamiliar with the details of the K-RBRVS and how it affects the reimbursement rates for the surgical procedures we perform. We summarize the K-RBRVS in brief, and discuss on how the relative value (RV) of the spinal neurosurgical procedures have changed since the introduction in 2001. Methods We analyzed the change of spinal procedure RVs since 2001, and compared it with the change of values in the brain neurosurgical procedures. RVs of 88 neurospinal procedures on the list of K-RBRVS were analyzed, while 24 procedures added during annual revisions were excluded. Results During the past 15 years, RVs for spinal procedures have increased 62.8%, which is not so different with the cumulative increase of consumer prices during this time period or the increase rate of 92.3% for brain surgeries. When comparing the change of RVs in more complex procedures between spinal and brain neurosurgery, the increase rate was 125.3% and 133%, respectively. Conclusion More effort of the society of spinal surgeons seems to be needed to get adequate reimbursement, as there have been some discrimination compared to brain surgeons in the increase of RVs. And considering the relative underestimation of spinal neurosurgeons’ labor, more objective measures of neurospinal surgeons’ work and productivity should be developed for impartial reimbursement.

    Full Text Available Object. We arranged a mini-invasive surgical approach for implantation of paddle electrodes for SCS under spinal anesthesia obtaining the best paddle electrode placement and minimizing patients’ discomfort. We describe our technique supported by neurophysiological intraoperative monitoring and clinical results. Methods. 16 patients, affected by neuropathic pain underwent the implantation of paddle electrodes for spinal cord stimulation in lateral decubitus under spinal anesthesia. The paddle was introduced after flavectomy and each patient confirmed the correct distribution of paresthesias induced by intraoperative test stimulation. VAS and patients’ satisfaction rate were recorded during the followup and compared to preoperative values. Results. No patients reported discomfort during the procedure. In all cases, paresthesias coverage of the total painful region was achieved, allowing the best final electrode positioning. At the last followup (mean 36.7 months, 87.5% of the implanted patients had a good rate of satisfaction with a mean VAS score improvement of 70.5%. Conclusions. Spinal cord stimulation under spinal anesthesia allows an optimal positioning of the paddle electrodes without any discomfort for patients or neurosurgeons. The best intraoperative positioning allows a better postoperative control of pain, avoiding the risk of blind placements of the paddle or further surgery for their replacement.

    Purpose Stereotactic radiotherapy using the Cyberknife has become a key treatment in the multidisciplinary management of secondary tumours, as well as primary benign or malignant tumours located within or adjacent to vertebral bodies and the spinal cord. The aim of this treatment is to improve local control and clinical response, including previously irradiated cases. Patients and methods In this study, we present the first patients treated with Cyberknife between December 2006 and December 2007 for spinal or para spinal tumours. The primary aim was to assess the feasibility and tolerance of stereotactic radiotherapy using the Cyberknife. Secondary aims were to establish the short-term local control, to calculate the local progression-free survival and overall survival. Clinical examination and imaging procedures were performed every three months. Response was assessed according to RECIST criteria. Results During that period, 16 patients were treated with Cyberknife. Thirteen patients had been pre-treated, three of whom had received spinal cord doses considered to be maximal. Three patients did not receive previous irradiation. The median age was 59 (36-74). The most frequent symptoms were pain (n = 8) and motor weakness (n = 4). The median dose was 30 Gy (16-50). The median number of fractions was 3 (1-5). No patient developed acute myelitis. Three patients developed acute reaction. Overall survival at 18 months was 72.4%, with a mean survival of 18.2 months (95% CI: 15.4-20.9). Local progression-free survival at 18 months was 58.4%, with a mean value of 16.9 months (95% CI: 13.6-20.2). Conclusion The use of stereotactic radiotherapy with Cyberknife represents a major progress in the management of para spinal tumours. The main advantages are better sparing of the spinal cord and the possibility of increasing the dose to the tumour target volume. (authors)

    Full Text Available BACKGROUND: Meningitis after neurosurgery can result in severe morbidity and high mortality. Incidence varies among regions and limited data are focused on meningitis after major craniotomy. AIM: This retrospective cohort study aimed to determine the incidence, risk factors and microbiological spectrum of postcraniotomy meningitis in a large clinical center of Neurosurgery in China. METHODS: Patients who underwent neurosurgeries at the Department of Neurosurgery in Huashan Hospital, the largest neurosurgery center in Asia and the Pacific, between 1st January and 31st December, 2008 were selected. Individuals with only shunts, burr holes, stereotactic surgery, transsphenoidal or spinal surgery were excluded. The complete medical records of each case were reviewed, and data on risk factors were extracted and evaluated for meningitis. RESULTS: A total of 65 meningitides were identified among 755 cases in the study, with an incidence of 8.60%. The risk of meningitis was increased by the presence of diabetes mellitus (odds ratio [OR], 6.27; P = 0.009, the use of external ventricular drainage (OR, 4.30; P = 0.003 and the use of lumbar drainage (OR, 17.23; P<0.001. The isolated microorganisms included Acinetobacter baumannii, Enterococcus sp, Streptococcus intermedius and Klebsiella pneumonia. CONCLUSIONS: Meningitis remains an important source of morbidity and mortality after major craniotomy. Diabetic patients or those with cerebral spinal fluid shunts carry significant high risk of infection. Thus, identification of the risk factors as soon as possible will help physicians to improve patient care.

    Ischemic/reperfusion (I/R) injury of the spinal cord is a serious complication that can result from thoracoabdominal aortic surgery. To investigate the neuroprotective effect of curcumin against I/R injury in a rabbit model. A total of 36 rabbits were randomly divided into three groups: sham, I/R, and curcumin-treated group. Rabbits were subject to 30-min aortic occlusion to induce transient spinal cord ischemia. Neurological function was observed after reperfusion and spinal cord segment (L3-L5) was collected for histopathological evaluation. Malondialdehyde (MDA) and total superoxide dismutase (SOD) activity were also assayed. Rabbits in I/R group were induced to paraplegia. While after 48-hour treatment, compared with I/R group, curcumin significantly improved neurological function, reduced cell apoptosis and MDA levels as well as increased SOD activity (P curcumin, at least in an animal model, can attenuate transient spinal cord ischemic injury potentially via reducing oxidative damage, which may provide a novel approach in the treatment of spinal cord ischemic injury.

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those with moderate or severe brain injury, the socioeconomic costs are significant. Since most of the spinal trauma patients survive their injuries, almost one out of 1000 inhabitants in the USA are currently being cared for partial or complete paralysis. Little controversy exists regarding the need for accurate and emergent imaging assessment of the traumatized spine in order to evaluate spinal stability and integrity of neural elements. Because clinicians fear missing occult spine injuries, they obtain radiographs for nearly all patients who present with blunt trauma. We are influenced on one side by fear of litigation and the possible devastating medical, psychologic and financial consequences of cervical spine injury, and on the other side by pressure to reduce health care costs. A set of clinical and/or anamnestic criteria, however, can be very useful in identifying patients who have an extremely low probability of injury and who consequently have no need for imaging studies. Multidetector (or multislice) computed tomography (MDCT) is the preferred primary imaging modality in blunt spinal trauma patients who do need imaging. Not only is CT more accurate in diagnosing spinal injury, it also reduces imaging time and patient manipulation. Evidence-based research has established that MDCT improves patient outcome and saves money in comparison to plain film. This review discusses the use, advantages and disadvantages of the different imaging techniques used in spinal trauma patients and the criteria used in selecting patients who do not need imaging. Finally an overview of different types of spinal injuries is given

    Objective: The spine is the most common location for bone metastases. Since cure is not possible, local control and relief of symptoms is the basis for treatment, which is grounded on the use of conventional radiotherapy. Recently, spinal radiosurgery has been proposed for the local control of spinal metastases, whether as primary or salvage treatment. Consequently, we carried out a literature review in order to analyze the indications, efficacy, and safety of radiosurgery in the treatment of spinal metastases. Methods: We have reviewed the literature using the PubMed gateway with data from the Medline library on studies related to the use of radiosurgery in treatment of bone metastases in spine. The studies were reviewed by all the authors and classified as to level of evidence, using the criterion defined by Wright. Results: The indications found for radiosurgery were primary control of epidural metastases (evidence level II), myeloma (level III), and metastases known to be poor responders to conventional radiotherapy – melanoma and renal cell carcinoma (level III). Spinal radiosurgery was also proposed for salvage treatment after conventional radiotherapy (level II). There is also some evidence as to the safety and efficacy of radiosurgery in cases of extramedullar and intramedullar intradural metastatic tumors (level III) and after spinal decompression and stabilization surgery. Conclusion: Radiosurgery can be used in primary or salvage treatment of spinal metastases, improving local disease control and patient symptoms. It should also be considered as initial treatment for radioresistant tumors, such as melanoma and renal cell carcinoma. (author)

    We present a rare and interesting case of hemorrhagic lumbar facet cysts accompanying a spinal subdural hematoma at the same level suggesting a possible mechanism by which spinal subdural hematomas can arise. A 71-year-old man presented with persistent sciatic pain and intermittent claudication. Magnetic resonance imaging demonstrated a multilocular mass lesion that showed high signal intensity in both T1- and T2-weighted images, and was located both inside and outside of the spinal canal. Computed tomographic myelography showed a cap-shaped block of the dural tube at L5 and computed tomography with L5-S facet arthrography demonstrated cystic masses. The patient was diagnosed with lumbar radiculopathy caused by hemorrhagic facet cysts, and then progressed to surgical treatment. Surgery revealed that the cysts contained blood clots, and intraoperative findings that the inside of the dural tube appeared blackish and that the dural tube was tensely ballooned after removal of the cysts led us to explorative durotomy. The durotomy demonstrated concentrated old blood pooling both in the dorsal and ventral subdural space, and these spaces were subsequently drained. After surgery, his sciatic pain and intermittent claudication resolved. There was no evidence of cyst mass recurrence at 2 years of follow-up. We propose a newly described mechanism for the formation of spinal subdural hematomas. We recommend surgeons be alert to epidural lesions causing repeated acute compression of the dural tube, which can cause spinal subdural hematoma, and consider the possible coexistence of these lesions in diagnosis and strategic surgical decisions.

    Spinal epidural hematoma (SEH) is a rare postoperative complication but can result in catastrophic neurological deficits requiring immediate surgical evacuation of the hematoma. Knowing the risk factors for postoperative SEH can help surgeons stratify patients. Therefore, to identify possible risk factors for postoperative SEH, we reviewed 6 clinical cases and examined the relation between postoperative hypertension and the risk of developing SEH. A retrospective review was conducted of 1282 consecutive patients who underwent spinal surgery at a single institution between 2010 and 2015. Of this cohort, 6 patients developed symptomatic SEH and underwent emergency hematoma evacuation. The 6 SEH patients were evaluated for previously described risk factors of postoperative hematoma formation. In particular, postoperative blood pressure measurements were reviewed. The incidence of postoperative symptomatic SEH was 0.468%. Two patients developed SEH secondary to a nonfunctional surgical drain in the early postoperative period (5 or 12 h post-surgery). Preoperative and postoperative hypertension was observed in 4 patients who developed SEH at greater than or equal to 48 h following surgery. Our findings suggest that rigorous postoperative blood pressure control may decrease the risk of SEH. © 2017 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    Spinal cord injury (SCI) is a highly devastating injury with a variety of complications; among them are neurogenic bladder, bowel, and sexual dysfunction. We aimed to evaluate the effect of sacral anterior root stimulation with sacral deafferentation (SARS-SDAF) on neurogenic bladder and sexual dysfunction in a large well-defined spinal cord injury cohort. In the manner of cross-sectional study, subjects undergone SARS-SDAF between September 1986 and July 2011 answered a questionnaire concerning conditions before and after surgery in the department of Neuro-Urology, Bad Wildungen, Germany. In total 287 of 587 subjects were analyzed. Median age was 49 years (range 19-80), median time from SCI to surgery was 10 years (range 0-49), and from surgery to follow-up 13 years (range 1-25). Of the analyzed subjects, 100% of both gender used SARS for bladder emptying. On the visual analogue scale (VAS) ranging from 0 to 10 (best), satisfaction with SARS-SDAF was 10 concerning bladder emptying, however 5 and 8 regarding sexual performance, for female and male users, respectively. Baseline and follow-up comparison showed a decline in self-intermittent catheterization (p < 0.0001), partial catheterization by attendant (p = 0.0125), complete catheterization and suprapubic catheterization (p < 0.0001), transurethral catheterization (p < 0.0011), and fewer cases of involuntary urine leakage (p < 0.0001). The SARS-SDAF is a beneficial multi-potential treatment method with simultaneous positive effect on multi-organ dysfunction among SCI subjects.

    Full Text Available Introduction: Intra-articular (IA local anesthetics are often used for the management and prevention of pain after arthroscopic knee surgery. Clonidine prolongs the duration of local anesthetics. In this study, analgesic effect of intra-articular administration of levobupivacaine and clonidine was compared with ropivacaine and clonidine in knee joint arthroscopic surgery under spinal anesthesia. Method: 88 patients, aged between 15 to 55 years, ASA I and II undergoing knee arthroscopy under spinal anesthesia were assigned into two equal groups (n = 44 in a randomized double blind protocol. Patients in Group L received 10 ml of 0.50% levobupivacaine and 1 mcg/kg clonidine and Group R received 10 ml of 0.75% ropivacaine and 1 mcg/kg of clonidine through intra-articular route at the end of the procedure. In the post-operative period, pain intensity was assessed by VAS (Visual Analogue Scale Score recorded at 1 st , 5 th , 8 th , 12 th , 18 th post-operative hours. Duration of analgesia, total rescue analgesic dose in first 18 hours and any side effects were also recorded. Result: Group L experienced significantly longer duration of effective postoperative analgesia and lesser rescue analgesic compared to group R. Group R had higher mean VAS score at 5 th and 12 th post-operative hours (P < 0.05. No side effects were observed among the groups. Conclusion: Intra-articular administration of levobupivacaine and clonidine give better post-operative pain relief by increasing duration of analgesia, and decreasing need of rescue analgesic compared to intra-articular ropivacaine and clonidine.

    Full Text Available Abstract Background Interspinous distraction devices (IPDD are indicated as stand-alone devices for the treatment of spinal stenosis. The purpose of this study is to evaluate the results of patients undergoing surgery for spinal stenosis with a combination of unilateral microdecompression and interspinous distraction device insertion. Methods This is a prospective clinical and radiological study of minimum 2 years follow-up. Twenty-two patients (average age 64.5 years with low-back pain and unilateral sciatica underwent decompressive surgery for lumbar spinal stenosis. Visual Analogue Scale, Oswestry Disability Index and walking capacity plus radiologic measurements of posterior disc height of the involved level and lumbar lordosis Cobb angle were documented both preoperatively and postoperatively. One-sided posterior subarticular and foraminal decompression was conducted followed by dynamic stabilization of the diseased level with an IPDD (X-STOP. Results The average follow-up time was 27.4 months. Visual Analogue Scale and Oswestry Disability Index improved statistically significantly (p Conclusions The described surgical technique using unilateral microdecompression and IPDD insertion is a clinically effective and radiologically viable treatment method for symptoms of spinal stenosis resistant to non-operative treatment.

    According to the literature, patients with neuromuscular scoliosis have a higher rate of infection after spinal fusion. No randomized controlled trials have been completed to assess the optimal treatment and related outcomes for patients with infections after posterior spinal fusion. In this article, we examine the data and report a case in which a vacuum-assisted closure (VAC) device was used as definitive treatment for a deep wound infection after posterior spinal fusion and instrumentation in a patient with neuromuscular scoliosis. Our patient, a 17-year-old adolescent girl with progressive neuromuscular scoliosis, underwent posterior spinal fusion with instrumentation and bone graft from T2 to sacrum without complication. One month after surgery, she presented with a draining wound. She underwent repeat surgical irrigation and debridement with subsequent use of a wound VAC. The wound VAC was used for more than 2 months, until skin closure was complete. The deep polymicrobial wound infection was treated successfully and definitively with a wound VAC. This case report suggests that good long-term outcomes can be achieved with use of a wound VAC for definitive closure, with possible avoidance of other secondary surgeries requiring skin grafts or flaps for wound closure.

    To determine the frequency of wound infection and neurological injuries in patients with idiopathic scoliosis who underwent posterior spinal fusion without use of drains. Study Design: Case series. Place and Duration of Study: Department of Orthopaedics, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, from February 2007 to June 2010. Methodology: Patients who underwent similar technique of posterior spinal fusion instrumentation for the correction of scoliosis without use of drain were included. Wound Demographics, wound healing, complications and duration of hospital stay were considered and described as frequency and mean values. Results: The average age at the time of surgery was 12.80 +- 1.30 years, duration of surgery was 3.80 +- 0.86 hours, hospital stay was 3.84 +- 0.78 days and patients were followed-up over the last 30 months. There was no incidence of any neurological complication and deep infection. However, only 2 (4.16%) cases with superficial skin infection were treated with dressing and antibiotics with full recovery. Conclusion: The wound healing is adequate without using drain for patients with idiopathic scoliosis who underwent posterior spinal fusion and instrumentation when good wash, watertight closure technique and appropriate antibiotics coverage is provided.

    Full Text Available Background: Stainless steel wiring remains the most popular technique for primary sternal closure. Recently, a multifilament cable wiring system (Pioneer Surgical Technology Inc., Marquette, MI, USA was introduced for sternal closure and has gained wide acceptance due to its superior resistance to tension. We aimed to compare conventional steel wiring to multifilament cable fixation for sternal closure in patients undergoing major cardiac surgery. Methods: Data were collected retrospectively on 1,354 patients who underwent sternal closure after major cardiac surgery, using either the multifilament cable wiring system or conventional steel wires between January 2009 and October 2010. The surgical outcomes of these two groups of patients were compared using propensity score matching based on 18 baseline patient characteristics. Results: Propensity score matching yielded 392 pairs of patients in the two groups whose baseline profiles showed no significant differences. No significant differences between the two groups were observed in the rates of early mortality (2.0% vs. 1.3%, p=0.578, major wound complications requiring reconstruction (1.3% vs. 1.3%, p>0.99, minor wound complications (3.6% vs. 2.0%, p=0.279, or mediastinitis (0.8% vs. 1.0%, p=1.00. Patients in the multifilament cable group had fewer sternal bleeding events than those in the conventional wire group, but this tendency was not statistically significant (4.3% vs. 7.4%, p=0.068. Conclusion: The surgical outcomes of sternal closure using multifilament cable wires were comparable to those observed when conventional steel wires were used. Therefore, the multifilament cable wiring system may be considered a viable option for sternal closure in patients undergoing major cardiac surgery.

    A 57-year-old man complained of severe lower back pain and radicular pain in both legs for 1 week after falling from a ladder. Magnetic resonance imaging (MRI) of the spine showed a subdural hematoma (SDH), which was surgically removed. The patient had no back pain or the radicular leg pain at 2 weeks post-surgery. However, he complained of diffuse headaches upon follow-up. Brain computed tomography (CT) and MRI revealed an intracranial SDH, which was immediately removed by surgery. During his 1-year follow-up, he reported that the pain had resolved without recurrence. Simultaneous spinal and intracranial SDH are rare and no standard treatment exists for this condition. This case suggests that it is possible that an intracranial SDH can migrate into the cerebrospinal fluid (CSF) space through an arachnoid tear. CSF circulation allows the intracranial SDH to enter subarachnoid spaces encasing the spinal cord. In order to prevent irreversible damage, surgical intervention should be considered for case of spinal SDH with progressive neurological deficits.

    Pre-existing cognitive impairment (CI) is emerging as a predictor of poor post-operative outcomes in elderly patients. Little is known about impaired preoperative cognition and outcomes after elective spine surgery in this patient population. The purpose of this study was to assess the prevalence of neuro CI in elderly patients undergoing deformity surgery and its impact on postoperative outcomes. Elderly subjects undergoing elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Pre-operative baseline cognition was assessed using the Saint Louis Mental Status (SLUMS) test. SLUMS consists of 11 questions, which can give a maximum of 30 points. Mild CI was defined as a SLUMS score between 21-26 points, while severe CI was defined as a SLUMS score of ≤20 points. Normal cognition was defined as a SLUMS score of ≥27 points. Complication rates, duration of hospital stay, and 30-day readmission rates were compared between patients with and without baseline CI. Eighty-two subjects were included in this study, with mean age of 73.26±6.08 years. Fifty-seven patients (70%) had impaired cognition at baseline. The impaired cognition group had the following outcomes: increased incidence of one or more postoperative complications (39% vs. 20%), higher incidence of delirium (20% vs. 8%), and higher rate of discharge institutionalization at skilled nursing or acute rehab facilities (54% vs. 30%). The length of hospital stay and 30-day hospital readmission rates were similar between both cohorts (5.33 vs. 5.48 days and 12.28% vs. 12%, respectively). CI is highly prevalent in elderly patients undergoing surgery for adult degenerative scoliosis. Impaired cognition before surgery was associated with higher rates of post-operative delirium, complications, and discharge institutionalization. CI assessments should be considered in the pre-operative evaluations of elderly patients prior to surgery.

    Full Text Available Line Jacques, Michael Safaee Department of Neurological Surgery, University of California, San Francisco, San Francisco, CA, USA Abstract: This paper is a review of some of the current research focused on using existing epidural spinal cord stimulation technologies in establishing the effectiveness in the recovery of independent standing, ambulation, or intentional movement of spinal cord injury patients. From a clinician’s perspective, the results have been intriguing, from a restorative perspective they are promising, and from a patient’s perspective they are hopeful. The outcomes, although still in the experimental phase, show some proof of theory and support further research. From a high volume university based clinician’s perspective, the resources needed to integrate this type of restorative care into a busy clinical practice are highly challenging without a well-structured and resource rich institutional restorative program. Patient selection is profoundly critical due to the extraordinary resources needed, and the level of motivation required to participate in such an intense and arduous rehabilitation process. Establishing an algorithmic approach to patient selection and treatment will be paramount to effectively utilize scarce resources and optimize outcomes. Further research is warranted, and the development of dedicated technological hardware and software for this therapeutic treatment versus using traditional spinal cord stimulation devices may yield more robust and efficacious outcomes.

    Full Text Available Abstract Background Lumbar spinal stenosis is one of the most common causes of low back pain among older adults and can cause significant disability. Despite its prevalence, treatment of spinal stenosis symptoms remains controversial. Epidural steroid injections are used with increasing frequency as a less invasive, potentially safer, and more cost-effective treatment than surgery. However, there is a lack of data to judge the effectiveness and safety of epidural steroid injections for spinal stenosis. We describe our prospective, double-blind, randomized controlled trial that tests the hypothesis that epidural injections with steroids plus local anesthetic are more effective than epidural injections of local anesthetic alone in improving pain and function among older adults with lumbar spinal stenosis. Methods We will recruit up to 400 patients with lumbar central canal spinal stenosis from at least 9 clinical sites over 2 years. Patients with spinal instability who require surgical fusion, a history of prior lumbar surgery, or prior epidural steroid injection within the past 6 months are excluded. Participants are randomly assigned to receive either ESI with local anesthetic or the control intervention (epidural injections with local anesthetic alone. Subjects receive up to 2 injections prior to the primary endpoint at 6 weeks, at which time they may choose to crossover to the other intervention. Participants complete validated, standardized measures of pain, functional disability, and health-related quality of life at baseline and at 3 weeks, 6 weeks, and 3, 6, and 12 months after randomization. The primary outcomes are Roland-Morris Disability Questionnaire and a numerical rating scale measure of pain intensity at 6 weeks. In order to better understand their safety, we also measure cortisol, HbA1c, fasting blood glucose, weight, and blood pressure at baseline, and at 3 and 6 weeks post-injection. We also obtain data on resource utilization

    Full Text Available Achondroplasia was first described in 1878 and is the most common form of human skeletal dysplasia. Spinal manifestations include thoracolumbar kyphosis, foramen magnum, and spinal stenosis. Progressive kyphosis can result in spinal cord compression and paraplegia due to the reduced size of spinal canal. The deficits are typically progressive, presenting as an insidious onset of paresthesia, followed by the inability to walk and then by urinary incontinence. Paraplegia can be the result of direct pressure on the cord by bone or the injury to the anterior spinal vessels by a protruding bone. Surgical treatment consists of posterior instrumentation, fusion with total wide laminectomy at stenosis levels, and anterior interbody support. Pedicle screws are preferred for spinal instrumentation because wires and hooks may induce spinal cord injury due to the narrow spinal canal. Pedicle lengths are significantly shorter, and 20–25 mm long screws are appropriate for lower thoracic and lumbar pedicles in adult achondroplastic There is no information about the appropriate length of screws for the upper thoracic pedicles. Tracheal injury due to inappropriate pedicle screw length is a rare complication. We report an extremely rare case of tracheal tear due to posterior instrumentation and its management in the early postoperative period.

    Full Text Available Objectives: This study aimed to investigate the long-term risk of stroke in adult patients with spinal deformity. Specifically, the study addressed the possible protective effect of surgery for spinal deformity against stroke. Methods: Using the National Health Insurance Research Database (NHIRD, a monopolistic national database in Taiwan, this retrospective cohort study analyzed the incidence of stroke in patients with adult spinal deformity (ASD in a 11-year period. A total of 13,503 patients, between 55 and 75 years old, were identified for the diagnosis of ASD. The patients were grouped into two: the surgical group (n = 10,439 who received spinal fusion surgery, and the control group (n = 2124 who received other medical treatment. The incidence rates of all subsequent cerebrovascular accidents, including ischemic and hemorrhagic strokes, were calculated. Hazard ratios for stroke were calculated use a full cohort and a propensity score matched cohort. Adjustments for co-morbidities that may predispose to stroke, including hypertension, diabetes mellitus, arrhythmia and coronary heart disease were conducted. Kaplan-Meier and Cox regression analyses were performed to compare the risk of stroke between the two groups. Results: During the total observation period of 50,450 person-years, the incidence rate of stroke in the surgical group (15.55 per 1000 person-years was significantly lower than that of the control group (20.89 per 1000 person-years, p < 0.001. Stroke was more likely to occur in the control group than in the surgical group (crude hazard ratio 1.34, p < 0.001; adjusted HR 1.28, p < 0.001, by a propensity score matched model. Conclusions: In this national cohort of more than 13,000 ASD patients covering 10 years, stroke was approximately 25% less likely to happen in patients who underwent spinal fusion surgery than those who received medical management. Therefore, spinal fusion surgery may provide a protective effect against stroke

    Failed back surgery syndrome (FBSS) is a term used to define an unsatisfactory outcome of a patient who underwent spinal surgery, irrespective of type or intervention area, with persistent pain in the lumbosacral region with or without it radiating to the leg. The possible reasons and risk factors that would lead to FBSS can be found in distinct phases: in problems already present in the patient before a surgical approach, such as spinal instability, during surgery (for example, from a mistake by the surgeon), or in the postintervention phase in relation to infections or biomechanical alterations. This article reviews the current literature on FBSS and tries to give a new hypothesis to understand the reasons for this clinical problem. The dysfunction of the diaphragm muscle is a component that is not taken into account when trying to understand the reasons for this syndrome, as there is no existing literature on the subject. The diaphragm is involved in chronic lower back and sacroiliac pain and plays an important role in the management of pain perception.

    a comprehensive assessment of the water balance on the basis of daily, cumulative balance and 10% of the body weight gain and their role in the development of early complications after major abdominal surgery. A retrospective study of the perioperative period in 150 patients who underwent major abdomi- nal surgery was performed. The physical condition of the patients corresponded to ASA 3 class. The average age was 46 (38-62) years. The following stages ofresearch: an analysis of daily balance and cumulative balance in complicated and uncomplicated group and their role in the development of complications; the timing of development ofcomplications and possible relationship with fluid overload and the development of complications; changes in the level of albumin within 10 days of the postoperative period. The analysis of complications didn't show significant differences between complicated and uncomplicated groups according to the water balance during the surgery and by the end of the first day. When constructing the area under the ROC curve (A UROC) low resolution ofthe balance in intraoperative period and the first day and the balance on the second day to predict complications was shown. Significant diferences according to the cumulative balance was observed from the third day of the postoperative period Also with the third day of the postoperative period there is a good resolution for prediction ofpostoperative complications according to the cumulative balance with the cut-offpoint > of 50,7 ml/kg. the excessive infusion therapy is a predictor of adverse outcome in patients after major abdominal surgery. Therefore, after 3 days of postoperative period it is important to maintain mechanisms for the excretion of excess fluid or limitations of infusion therapy.

    OBJECTIVE Proximal junctional kyphosis (PJK) is a well-recognized, yet incompletely defined, complication of adult spinal deformity surgery. There is no standardized definition for PJK, but most studies describe PJK as an increase in the proximal junctional angle (PJA) of greater than 10°-20°. Ligament augmentation is a novel strategy for PJK reduction that provides strength to the upper instrumented vertebra (UIV) and adjacent segments while also reducing junctional stress at those levels. METHODS In this study, ligament augmentation was used in a consecutive series of adult spinal deformity patients at a single institution. Patient demographics, including age; sex; indication for surgery; revision surgery; surgical approach; and use of 3-column osteotomies, vertebroplasty, or hook fixation at the UIV, were collected. The PJA was measured preoperatively and at last follow-up using 36-inch radiographs. Data on change in PJA and need for revision surgery were collected. Univariate and multivariate analyses were performed to identify factors associated with change in PJA and proximal junctional failure (PJF), defined as PJK requiring surgical correction. RESULTS A total of 200 consecutive patients were included: 100 patients before implementation of ligament augmentation and 100 patients after implementation of this technique. The mean age of the ligament augmentation cohort was 66 years, and 67% of patients were women. Over half of these cases (51%) were revision surgeries, with 38% involving a combined anterior or lateral and posterior approach. The mean change in PJA was 6° in the ligament augmentation group compared with 14° in the control group (p historical cohort, ligament augmentation is associated with a significant decrease in PJK and PJF. These data support the implementation of ligament augmentation in surgery for adult spinal deformity, particularly in patients with a high risk of developing PJK and PJF.

    The clinical course of spinal cord tumors in 24 non-operated patients who were followed by MRI for more than 1 year was investigated retrospectively. Only 7 patients were positive in neurological symptoms. 7 patients had multiple tumors, and the histopathologic diagnosis in 16 patients was neurinoma. The MRI findings changed in 4 patients, and follow-up MR images showed rapid growth of 2 neurinomas. The clinical manifestations did not change in 17 patients, but they improved in 3 patients whose symptoms were not caused by tumors and improved after temporary worsening caused by tumor growth in 2 patients. They worsened in 2 patients with intramedullary tumors associated with neurological symptoms. The diameter of the spinal cord of the patients with intramedullary tumors increased, making the spinal cord susceptible to both anterior and posterior compression. Finally, the clinical course of the patients with spinal cord tumors did not deteriorate rapidly, except in the patients with intramedullary tumor associated with neurological manifestations. We concluded that when spinal cord tumors that are asymptomatic or associated with minor symptoms are diagnosed as neurinoma or neurofibroma based on the MRI findings, early surgery should not be performed and followed by meticulous follow-up.

    The surgical strategy for spinal meningiomas usually consists of laminectomy, initial tumour debulking, identification of the interface between tumour and spinal cord, resection of the dura including the matrix of the tumour, and duroplasty. The objective of this study was to investigate whether a less invasive surgical strategy consisting of hemilaminectomy or laminectomy, tumour removal and coagulation of the tumour matrix allows comparable surgical and clinical results to be obtained, especially without an increase of the recurrence rate as reported in the literature. Between 1990 and 2005, 61 patients (11 men, 50 women) underwent surgery for spinal meningioma. All patients were treated microsurgically by a posterior approach. In 56 of the 61 patients, the above outlined - less invasive - surgical technique with tumour removal and coagulation of the tumour matrix was performed. In 5 patients, dura resection and duroplasty was additionally performed. Electrophysiological monitoring was routinely used since 1996. Recurrence was defined as new onset or worsening of symptoms and radiological confirmation of tumour growth. The pre-and post-operative clinical status was measured by the Frankel grading system. Pre-operatively, 40 patients were in Frankel grade D, 13 patients in grade C, 6 patients in grade E and 1 patient each in grade A and B. Following surgery no patient presented a permanent worsening of clinical symptoms. All patients who initially presented with a Frankel grades A-C (n = 15) recovered to a better grade at the time of follow-up. Patients who presented with Frankel grade D remained in stable condition (n = 27) or recovered to a better neurological status (n = 13). Two patients experienced a temporary worsening of their symptoms, but subsequently improved to a better state than pre-operatively.

    Occasionally, the outcome from laminoplasty for cervical spondylosis is disappointing despite an adequate operation. Before surgery, it is difficult to diagnose the pathological extent of the involvement of the spinal cord. The purpose of this study is to determine the efficacy of magnetic resonance imaging (MRI) and of the motor evoked potentials (MEPs) for the indication of the surgery and prognosis. Retrospectively, we investigated the MEPs and the MRI of 31 patients in surgery for cervical myelopathy, involving 21 with cervical spondylosis and 10 with ossification of the posterior longitudinal ligamentum, and compared the findings from those with a poor outcome (n=3l) with the findings from those with a good outcome (n=32). The MEPs from the thenar muscle and the tibialis anterior were evoked by transcranial magnetic brain stimulation. In the poor-outcome patients, the spinal canal was narrow and lumbar spinal canal stenosis was seen in 5 cases which required lumbar laminectomy. Before operation, the MEPs from the thenar muscle could not be evoked in 5 cases while there was a remarkably prolonged central motor conduction time in the other 26 cases. MRI revealed the deformed spinal cord in the involved area, and the signal intensity of the involved spinal cord in the T2 weighted image was remarkably high. The signal intensity ratio was significantly higher in the poor-outcome patients than in the good-outcome patients. This study suggested that a high signal intensity in the T2 weighted image and a prolonged conduction time or absence of MEPs largely corresponded to the clinical and other investigative features of myelopathy responsible for a poor outcome.

    An unusual case is reported in which a patient sustained a third-degree burn of the plantar surface of the right foot as the result of contact with a heating radiator. This occurred when the patient fell asleep in his hospital bed after knee surgery. Spinal anaesthesia is easy to perform, and the risk factors, though present, are not serious. Such accidents are not infrequent and care should be taken to prevent them.

    The duration of spinal anesthesia with bupivacaine is often too long for day surgery. A recent study of patients presenting for transurethral surgery suggested that the addition of a small amount of lidocaine to intrathecal hyperbaric bupivacaine could shorten the duration of the sensory and moto...... blocks. In this prospective, randomized double-blind study we investigated these findings in patients undergoing unilateral knee arthroscopy....

    Addition of fentanyl to hyperbaric bupivacaine spinal anesthesia prolonged the duration of sensory block. This study seeks to test the hypothesis that adding fentanyl to small dose hypobaric spinal anesthesia will improve intraoperative patients and surgeon satisfaction without delay in recovery. Patients (n = 80) subjected to minor cystoscopic surgery were randomly assigned to have spinal anesthesia with either 5 mg bupivacaine 0.1% or 5 mg bupivacaine 0.1% mixed with 20 micrograms fentanyl. The main outcome measures included intraoperative patient and endoscopist satisfaction, sedative/analgesic supplementation, postoperative side effects and time to ambulation. Patients in the bupivacaine group needed more analgesic supplementation. Analgesia was more adequate in the bupivacaine-fentanyl group. Pruritus was the main side effect in the bupivacaine fentanyl group. Ambulation and discharge of patients were nearly the same in both groups. Spinal anesthesia with small dose (5 mg) hypobaric (0.1%) bupivacaine mixed with fentanyl (20 micrograms) produced adequate anesthesia for short cystoscopic procedures with minimal side effects and without delay in ambulation.

    The practice of neurosurgery requires fundamental knowledge base. Residency training programs and continuing medical education courses are designed to teach relevant neurosurgical principles. Nevertheless, knowledge gaps exist for neurosurgeons and may be different between cohorts of neurosurgeons. The Self-Assessment in Neurological Surgery (SANS) General Examination and Spine Examination are online educational tools for lifelong learning and maintenance of certification. This study examines the gaps in knowledge of spinal neurosurgeons and general neurosurgeons taking SANS. From 2008 to 2010, a total of 165 spinal neurosurgeons completed the 243 available questions of the SANS Spine Examination. Over that same time frame, 993 general neurosurgeons completed the SANS General Spine Examination. Mean scores were calculated and assessed according to 18 major neurosurgical knowledge disciplines. Statistical analysis was carried out to evaluate for significant knowledge gaps among all users and significant differences in performance between spinal neurosurgeons and their general neurosurgeon counterparts. The mean overall examination score was 87.4% ± 7.5% for spinal neurosurgeons and 71.5% ± 8.9% for general neurosurgeons (P neurosurgeons (n = 165) answered questions incorrectly 15% or greater of the time in five of the categories. The categories of lower performance for spinal neurosurgeons were cerebrovascular, anesthesia and critical care, general clinical, tumor, and trauma. For general neurosurgeons (n = 993), the five knowledge categories with lowest performance were cerebrovascular, epilepsy, peripheral nerve, trauma, and radiosurgery. Although spinal neurosurgeons and general neurosurgeons shared some areas of decreased performance including trauma and cerebrovascular, spine neurosurgeons relatively underperformed in general clinical, anesthesia and critical care, and tumor. The SANS Spine Examination demonstrated knowledge gaps in specific categories for

    Full Text Available During perinatal development, corticospinal tract (CST projections into the spinal cord help refine spinal circuitry. Although the normal developmental processes that are controlled by the arrival of corticospinal input are becoming clear, little is known about how perinatal cortical damage impacts specific aspects of spinal circuit development, particularly the inhibitory microcircuitry that regulates spinal reflex circuits. In this study, we sought to determine how ischemic cortical damage impacts the synaptic attributes of a well-characterized population of inhibitory, GABAergic interneurons, called GABApre neurons, which modulates the efficiency of proprioceptive sensory terminals in the sensorimotor reflex circuit. We found that putative GABApre interneurons receive CST input and, using an established mouse model of perinatal stroke, that cortical ischemic injury results in a reduction of CST density within the intermediate region of the spinal cord, where these interneurons reside. Importantly, CST alterations were restricted to the side contralateral to the injury. Within the synaptic terminals of the GABApre interneurons, we observed a dramatic upregulation of the 65-isoform of the GABA synthetic enzyme glutamic acid decarboxylase (GAD65. In accordance with the CST density reduction, GAD65 was elevated on the side of the spinal cord contralateral to cortical injury. This effect was not seen for other GABApre synaptic markers or in animals that received sham surgery. Our data reveal a novel effect of perinatal stroke that involves severe deficits in the architecture of descending spinal pathways, which in turn appear to promote molecular alterations in a specific spinal GABAergic circuit.

    Full Text Available Degree of hernia size influence on final result of PLME in 34 patients with discogenic neurocompressive lumbar spinal syndrome was detected. In medical center "Endoscopic Neurosurgery" from 2006 to 2010 we examined and treated 34 patients with hernia size from 6 to 8 mm by CT data. Patients were from 19 to 49 years of age. Average age was 35.9 ± 1.5 years. Males – 16 (47.1%, females – 18 (52.9%. Disease duration – 5.53 ± 0.44 months with duration of last exacerbation – 1.87 ± 0.21 months. Duration of conservative therapy is 4.6 ± 2.1 weeks. During survey and objec¬tive examination we determined pain syndrome intensity, pain location, degree of spinal static – dynamic function disorder. Neurological examination determined severity of sensory and motor disorders. Pain syndrome intensity, quality of life in patients before and after surgery, surgery effectiveness were determined by common scales: VAS, OSWESTRY, Roland - Morris, McNab. Before PLME we evaluated preoperative spondylograms performed with functional load. Height of intervertebral fissure was determined by these images. By SCT and MRI data we measured hernia size, its shape and location as well as intervertebral disk dehydration degree. For PLME performance we used neodymium laser with aluminum garnet (Dorinyer Fibertom Medilas 4060 with wave-length of 1.06 micrometers. In the next period of observation after PLME its effectiveness was 79%, and in 3-5 years - 76%. At the same time it must be emphasized that 75% of patients with discogenic neurocompressive lumbar spinal syndrome significantly and for a long time improved their life quality avoiding more traumatic surgery. Satisfactory results with PLM use in the nearest future could be obtained in 79% of patients, in the remote term - in 76% of patients with large hernia size.

    The peri-operative cytokine response was studied in 13 infants and young children undergoing major surgery. All children were anaesthetized with a combined general and epidural anaesthetic technique, followed by post-operative epidural analgesia with bupivacaine and fentanyl. Blood samples were...... taken before and after surgery, 24 h post-operatively, and finally, when the children were mobilized and had regained gastrointestinal function. Plasma samples were analysed for tumour necrosis factor-alpha, interleukin-1 alpha, interleukin-1 beta, interleukin-6, interferon-gamma, interleukin-10...... and the interleukin-1 receptor antagonist. The cytokine responses were highly variable. Overall, no significant changes between pre- and post-operative plasma concentrations were found.

    Spinal dural arterio-venous fistula (SDAVF) is an uncommon and easily misdiagnosed vascular malformation. We aimed to report the diagnosis and management of a case with SDAVF. A 62-year-old man suffered from acute paraparesis about 15 months before this study. He underwent a neurosurgical procedure for herniated discs of the cervical spine at that time but there was no relief and the symptoms worsened despite the surgery. Neurologically, he had spastic paraparesis and decreased vibration sensation of the lower limbs. Spinal magnetic resonance imaging (MRI) revealed intra-medullary hyper-intensity lesion at T8 to T10 levels and tubular-like signal void structures in the corresponding posterior sub-arachnoid space. Further trans-arterial angiography through right T6 intercostal artery catheterization revealed engorged veins, thereby confirming the diagnosis of SDAVF. The patient was treated via endovascular embolization (18% Onyx, EV3TM MIT, Bonn, Germany) through spinal angiography and the results showed a marked decrease in engorged veins. After a 4-month follow-up, the patient was symptomatic but stable. Follow-up MRI showed a complete disappearance of the hyper-intensity change of the spinal cord. Spinal MR angiography did not reveal any recurrence of SDAVF. This case study demonstrated the easily misdiagnosed state of SDAVF. Serial neuroimage studies including spinal MRI, endovascular embolization through spinal angiography and MR angiography can be useful tools for its diagnostic confirmation, management and follow-up study.

    Introduction: The review evaluates the up-to-date evidence for the treatment of spinal deformities, including scoliosis and hyperkyphosis in adolescents and adults. Material and Methods: The PubMed database was searched for review articles, prospective controlled trials and randomized controlled trials related to the treatment of spinal deformities. Articles on syndromic scoliosis were excluded and so were the articles on hyperkyphosis of the spine with causes other than Scheuermann’s disease and osteoporosis. Articles on conservative and surgical treatments of idiopathic scoliosis, adult scoliosis and hyperkyphosis were also included. For retrospective papers, only studies with a follow up period exceeding 10 years were included. Results: The review showed that early-onset idiopathic scoliosis has a worse outcome than late-onset idiopathic scoliosis, which is rather benign. Patients with AIS function well as adults; they have no more health problems when compared to patients without scoliosis, other than a slight increase in back pain and aesthetic concern. Conservative treatment of adolescent idiopathic scoliosis (AIS) using physiotherapeutic scoliosis-specific exercises (PSSE), specifically PSSR and rigid bracing was supported by level I evidence. Yet to date, there is no high quality evidence (RCT`s) demonstrating that surgical treatment is superior to conservative treatment for the management of AIS. For adult scoliosis, there are only a few studies on the effectiveness of PSSEs and a conclusion cannot as yet be drawn. For hyperkyphosis, there is no high-quality evidence for physiotherapy, bracing or surgery for the treatment of adolescents and adults. However, bracing has been found to reduce thoracic hyperkyphosis, ranging from 55 to 80° in adolescents. In patients over the age of 60, bracing improves the balance score, and reduces spinal deformity and pain. Surgery is indicated in adolescents and adults in the presence of progression of kyphosis

    Fatalities or injuries following motorized and non-motorized vehicle accidents (MNMVA) are reported by police or health care systems. However, limited data exist for spinal injuries. Using an epidemiological database of road accidents occurring in a defined geographic area, we measured the incidence of major spinal trauma (MST, Abbreviated Injury Scale [AIS] score 2 or more), spinal cord injury (SCI, AIS score 4 or more), and associated lesions over a 10-year period (1997-2006). Among the 97,341 victims included, 21,623 (22.2%) suffered spinal trauma, but only 1523 (1.6%) and 144 (0.2%) sustained an MST or SCI, respectively, and among those 10% and 43% died, respectively, before reaching hospital facilities. Men were more likely to have SCI and die. Cervical injuries were more frequently observed for SCI (58%) than for MST (39%; p spinal trauma, and SCI after MNMVA.

  4. Diagnosis and management of traumatic cervical central spinal cord injury: A review.

    2015-01-01

    The classical clinical presentation, neuroradiographic features, and conservative vs. surgical management of traumatic cervical central spinal cord (CSS) injury remain controversial. CSS injuries, occurring in approximately 9.2% of all cord injuries, are usually attributed to significant hyperextension trauma combined with congenital/acquired cervical stenosis/spondylosis. Patients typically present with greater motor deficits in the upper vs. lower extremities accompanied by patchy sensory loss. T2-weighted magnetic resonance (MR) scans usually show hyperintense T2 intramedullary signals reflecting acute edema along with ligamentous injury, while noncontrast computed tomography (CT) studies typically show no attendant bony pathology (e.g. no fracture, dislocation). CSS constitute only a small percentage of all traumatic spinal cord injuries. Aarabi et al. found CSS patients averaged 58.3 years of age, 83% were male and 52.4% involved accidents/falls in patients with narrowed spinal canals (average 5.6 mm); their average American Spinal Injury Association (ASIA) motor score was 63.8, and most pathology was at the C3-C4 and C4-C5 levels (71%). Surgery was performed within 24 h (9 patients), 24-48 h (10 patients), or after 48 h (23 patients). In the Brodell et al. study of 16,134 patients with CSS, 39.7% had surgery. In the Gu et al. series, those with CSS and stenosis/ossification of the posterior longitudinal ligament (OPLL) exhibited better outcomes following laminoplasty. Recognizing the unique features of CSS is critical, as the clinical, neuroradiological, and management strategies (e.g. conservative vs. surgical management: early vs. late) differ from those utilized for other spinal cord trauma. Increased T2-weighted MR images best document CSS, while CT studies confirm the absence of fracture/dislocation.

    We measured the cross-sectional area (CSA) of the psoas major muscles of 48 male patients under 50 years of age with unilateral sciatica caused by a single-level lumbar disc herniation. Patients who had multi-level disc lesions, lumbar canal stenosis, spondylolisthesis, scoliosis>5deg, or a history of lumbar surgery or hip joint disease were excluded. Mean age at surgery was 33 years old. Two orthopedic surgeons measured the CSA independently and blindly on magnetic resonance images in which the spinal canal had been blacked out. The CSA ratio (pain-positive side/pain-negative side) was 0.99 at L3/4, 0.98 at L4/5, and 1.00 at L5/S. There was a statistically significant difference between the CSA of the psoas major muscle on the painful side and the unaffected side at L4/5 (p=0.02). There was no correlation between the CSA ratio and the angle in the straight leg raising test, the duration of symptoms, or the size of the disc herniation. The atrophy of the psoas major muscle observed on the pain-positive side in lumbar disc herniation patients may be attributable to disuse of the affected leg. (author)

    Objectives. The aim of the current study was to mimic mechanical impacts on the spinal cord by manifesting the effects of dorsoventral (DVMP) and lateral (LMP) mechanical pressure on neural activity to address points to be considered during surgery for different purposes, including spinal cord decompression. Approaches. Spinal cords of anesthetized rats were compressed at T13. Different characteristics of axons, including vulnerability, excitability, and conduction velocity (CV), in response to promptness, severity, and duration of pressure were assessed by spinal cord evoked potentials (SCEPs). Real-time SCEPs recorded at L4-5 revealed N1, N2, and N3 peaks that were used to represent the activity of injured sensory afferents, interneurons, and MN fibers. The averaged SCEP recordings were fitted by trust-region algorithm to find the equivalent Gaussian and polynomial equations. Main results. The pyramidal and extrapyramidal pathways possessed CVs of 3-11 and 16-80 m s-1, respectively. DVMP decreased the excitability of myelinated neural fibers in antidromic and orthodromic pathways. The excitability of fibers in extrapyramidal and pyramidal pathways of lateral corticospinal (LCS) and anterior corticospinal (ACS) tracts decreased following LMP. A significant drop in the amplitude of N3 and its conduction velocity (CV) revealed higher susceptibility of less-myelinated fibers to both DVMP and LMP. The best parametric fitting model for triplet healthy spinal cord CAP was a six-term Gaussian equation (G6) that fell into a five-term equation (G5) at the complete compression stage. Significance. The spinal cord is more susceptible to dorsoventral than lateral mechanical pressures, and this should be considered in spinal cord operations. SCEPs have shown promising capabilities for evaluating the severity of SCI and thus can be applied for diagnostic or prognostic intraoperative monitoring (IOM).

    Spinal sagittal imbalance is a widely acknowledged problem, but there is insufficient knowledge regarding its occurrence. In some patients with lumbar disc herniation (LDH), their symptom is similar to spinal sagittal imbalance. The aim of this study is to illustrate the spinopelvic sagittal characteristics and identity the role of spinal musculature in the mechanism of sagittal imbalance in patients with LDH. Twenty-five adults with spinal sagittal imbalance who initially came to our clinic for treatment of LDH, followed by posterior discectomy were reviewed. The horizontal distance between C7 plumb line-sagittal vertical axis (C7PL-SVA) greater than 5 cm anteriorly with forward bending posture is considered as spinal sagittal imbalance. Radiographic parameters including thoracic kyphotic angle (TK), lumbar lordotic angle (LL), pelvic tilting angle (PT), sacral slope angle (SS) and an electromyography(EMG) index 'the largest recruitment order' were recorded and compared. All patients restored coronal and sagittal balance immediately after lumbar discectomy. The mean C7PL-SVA and trunk shift value decreased from (11.6 ± 6.6 cm, and 2.9 ± 6.1 cm) preoperatively to (-0.5 ± 2.6 cm and 0.2 ± 0.5 cm) postoperatively, while preoperative LL and SS increased from (25.3° ± 14.0° and 25.6° ± 9.5°) to (42.4° ± 10.2° and 30.4° ± 8.7°) after surgery (P imbalance caused by LDH is one type of compensatory sagittal imbalance. Compensatory mechanism of spinal sagittal imbalance mainly includes a loss of lumbar lordosis, an increase of thoracic kyphosis and pelvis tilt. Spinal musculature plays an important role in spinal sagittal imbalance in patients with LDH.

    There has been a marked increase in spine surgery in the 21st century, but there are no reports providing quantitative and qualitative analyses of research by Korean spine surgeons. The study goal was to assess the status of Korean spinal surgery and research. The number of spine surgeries was obtained from the Korean National Health Insurance Service. Research articles published by Korean spine surgeons were reviewed by using the Medline/PubMed online database. The number of spine surgeries in Korea increased markedly from 92,390 in 2004 to 164,291 in 2013. During the 2000-2014 period, 1982 articles were published by Korean spine surgeons. The annual number of articles increased from 20 articles in 2000 to 293 articles in 2014. There was a positive correlation between the annual spine surgery and article numbers (particles with Oxford levels of evidence 1, 2, and 3. The mean five-year impact factor (IF) for article quality was 1.79. There was no positive correlation between the annual IF and article numbers. Most articles (65.9%) were authored by neurosurgical spine surgeons. But spinal deformity-related topics were dominant among articles authored by orthopedics. The results show a clear quantitative increase in Korean spinal surgery and research over the last 15years. The lack of a correlation between annual IF and published article numbers indicate that Korean spine surgeons should endeavor to increase research value. Copyright © 2016 Elsevier Ltd.

    Background To evaluate the effect of spondylolisthesis on lumbar lordosis on the OSI (Jackson; Orthopaedic Systems Inc.) frame. Restoration of lumbar lordosis is important for maintaining sagittal balance. Physiologic lumbar lordosis has to be gained by intraoperative prone positioning with a hip extension and posterior instrumentation technique. There are some debates about changing lumbar lordosis on the OSI frame after an intraoperative prone position. We evaluated the effect of spondylolisthesis on lumbar lordosis after an intraoperative prone position. Methods Sixty-seven patients, who underwent spinal fusion at the Department of Orthopaedic Surgery of Gwangmyeong Sungae Hospital between May 2007 and February 2012, were included in this study. The study compared lumbar lordosis on preoperative upright, intraoperative prone and postoperative upright lateral X-rays between the simple stenosis (SS) group and spondylolisthesis group. The average age of patients was 67.86 years old. The average preoperative lordosis was 43.5° (± 14.9°), average intraoperative lordosis was 48.8° (± 13.2°), average postoperative lordosis was 46.5° (± 16.1°) and the average change on the frame was 5.3° (± 10.6°). Results Among all patients, 24 patients were diagnosed with simple spinal stenosis, 43 patients with spondylolisthesis (29 degenerative spondylolisthesis and 14 isthmic spondylolisthesis). Between the SS group and spondylolisthesis group, preoperative lordosis, intraoperative lordosis and postoperative lordosis were significantly larger in the spondylolisthesis group. The ratio of patients with increased lordosis on the OSI frame compared to preoperative lordosis was significantly higher in the spondylolisthesis group. The risk of increased lordosis on frame was significantly higher in the spondylolisthesis group (odds ratio, 3.325; 95% confidence interval, 1.101 to 10.039; p = 0.033). Conclusions Intraoperative lumbar lordosis on the OSI frame with a prone

    OBJECTIVE Surgically created lesions of the spinal cord dorsal root entry zone (DREZ) to relieve central pain after spinal cord injury (SCI) have historically been performed at and cephalad to, but not below, the level of SCI. This study was initiated to investigate the validity of 3 proposed concepts regarding the DREZ in SCI central pain: 1) The spinal cord DREZ caudal to the level of SCI can be a primary generator of SCI below-level central pain. 2) Neuronal transmission from a DREZ that generates SCI below-level central pain to brain pain centers can be primarily through sympathetic nervous system (SNS) pathways. 3) Perceived SCI below-level central pain follows a unique somatotopic map of DREZ pain-generators. METHODS Three unique patients with both intractable SCI below-level central pain and complete spinal cord transection at the level of SCI were identified. All 3 patients had previously undergone surgical intervention to their spinal cords-only cephalad to the level of spinal cord transection-with either DREZ microcoagulation or cyst shunting, in failed attempts to relieve their SCI below-level central pain. Subsequent to these surgeries, DREZ lesioning of the spinal cord solely caudal to the level of complete spinal cord transection was performed using electrical intramedullary guidance. The follow-up period ranged from 1 1/2 to 11 years. RESULTS All 3 patients in this study had complete or near-complete relief of all below-level neuropathic pain. The analyzed electrical data confirmed and enhanced a previously proposed somatotopic map of SCI below-level DREZ pain generators. CONCLUSIONS The results of this study support the following hypotheses. 1) The spinal cord DREZ caudal to the level of SCI can be a primary generator of SCI below-level central pain. 2) Neuronal transmission from a DREZ that generates SCI below-level central pain to brain pain centers can be primarily through SNS pathways. 3) Perceived SCI below-level central pain follows a unique

    Full Text Available Remote cerebellar hemorrhage after cranial and spinal surgeries is a well-documented entity, so far concomitant supra- and infra-tentorial hemorrhage after spine surgery has rarely been reported in the literature. A 57-year-old woman presented with intractable low back pain and severely impaired mobility. One year ago, she underwent lumbar laminectomy and fusion with posterior spinal instrumentation between L2 and S1. She developed adjacent segment disease at the upper level of the instrumented vertebra. She had a revision surgery and underwent posterior laminectomy and fusion with bilateral transpedicular instrumentation between T10 and S1. She had severe headache, somnolence, and left hemiparesia 48 h after the surgery. Her emergent head computed tomography depicted intra-parenchymal hemorrhage in the right parietal lobe accompanying with subarachnoid hemorrhage, bilateral symmetrical cerebellar hemorrhages and pneumocephalus. She was treated nonsurgically and she got better despite some residual deficits. Symptoms including constant headache, nausea, vomiting, impaired consciousness, new onset seizure, and focal neurological deficit after spine surgeries should raise suspicion for intracranial intra-parenchymal hemorrhage.

    Noncontiguous double-level unstable spinal injuries (NDUSI) are uncommon and have not been well described. In this study, we aimed to better understand the patterns of NDUSI, in order to recommend proper diagnostic and treatment methods, as well as to raise awareness among traumatologists about the possibility of these uncommon injuries. A total of 710 consecutive patients with spine fractures were treated for >9 years since 2007 at a single regional trauma center. Of them, 18 patients with NDUSI were reviewed retrospectively. The incidence of NDUSI was 2.5 % of all spine fractures. In 17 of 18 patients (94.7 %), NDUSI was caused by a high-energy trauma. Nine patients (50.0 %) exhibited complete neurological deficit. Spinal cord injury occurred in the cranial injured region in all American Spinal Injury Association grade A cases. In one case, a second fracture was overlooked at the initial examination. NDUSI are common in cases of high-energy trauma and should be taken into consideration at the initial examination. A second fracture may be easily overlooked because of the high frequency of concomitant severe spinal cord injury in the cranial injured region and/or loss of consciousness due to associated injuries. To avoid overlooking injuries, full spine computed tomography is useful at the initial examination. Operative reduction and internal fixation with instrumentation through a posterior approach is recommendable for cases of NDUSI. In elderly patients, a very rapid stabilizing surgery should be planned before aspiration pneumonia occurs or the pulmonary condition worsens.

    The authors present a new posterior correction technique consisting of simultaneous double-rod rotation using 2 contoured rods and polyaxial pedicle screws with or without Nesplon tapes. The purpose of this study is to introduce the basic principles and surgical procedures of this new posterior surgery for correction of adolescent idiopathic scoliosis. Through gradual rotation of the concave-side rod by 2 rod holders, the convex-side rod simultaneously rotates with the the concave-side rod. This procedure does not involve any force pushing down the spinal column around the apex. Since this procedure consists of upward pushing and lateral translation of the spinal column with simultaneous double-rod rotation maneuvers, it is simple and can obtain thoracic kyphosis as well as favorable scoliosis correction. This technique is applicable not only to a thoracic single curve but also to double major curves in cases of adolescent idiopathic scoliosis.

    Opossums are born in an immature, fetal-like state, making it possible to lesion their spinal cord early in development without intrauterine surgery. When the thoracic spinal cord of the North American opossum, Didelphis virginiana, is transected on postnatal day 5, and injections of Fast Blue (FB) are made caudal to the lesion site 30-40 days or 6 months later, neurons are labeled in all of the spinal and supraspinal areas that are labeled after comparable injections in age-matched, unlesioned controls. Double-labeling studies document that regeneration of cut axons contributes to growth of axons through the lesion site and behavioral studies show that animals lesioned on postnatal day 5 use their hindlimbs in normal appearing locomotion as adults. The critical period for developmental plasticity of descending spinal axons extends to postnatal day 26, although axons which grow through the lesion site become fewer in number and more restricted as to origin with increasing age. Animals lesioned between postnatal day 12 and 26 use the hindlimbs better than animals lesioned as adults, but hindlimb function is markedly abnormal and uncoordinated with that of the forelimbs. We conclude that restoration of anatomical continuity occurs after transection of the spinal cord in developing opossums, that descending axons grow through the lesion site, that regeneration of cut axons contributes to such growth, and that animals lesioned early enough in development have relatively normal motor function as adults.

    Purpose: To identify the prognostic factors for spinal cord astrocytoma and determine the effects of surgery and radiotherapy on outcome. Methods and Materials: This retrospective study reviewed the cases of consecutive patients with spinal cord astrocytoma treated at Mayo Clinic Rochester between 1962 and 2005. Results: A total of 136 consecutive patients were identified. Of these 136 patients, 69 had pilocytic and 67 had infiltrative astrocytoma. The median follow-up for living patients was 8.2 years (range, 0.08-37.6), and the median survival for deceased patients was 1.15 years (range, 0.01-39.9). The extent of surgery included incisional biopsy only (59%), subtotal resection (25%), and gross total resection (16%). Patients with pilocytic tumors survived significantly longer than those with infiltrative astrocytomas (median overall survival, 39.9 vs. 1.85 years; p < 0.001). Patients who underwent resection had a worse, although nonsignificant, median survival than those who underwent biopsy only (pilocytic, 18.1 vs. 39.9 years, p = 0.07; infiltrative, 19 vs. 30 months, p = 0.14). Postoperative radiotherapy, delivered in 75% of cases, gave no significant survival benefit for those with pilocytic tumors (39.9 vs. 18.1 years, p = 0.33) but did for those with infiltrative astrocytomas (24 vs. 3 months; Wilcoxon p = 0.006). On multivariate analysis, pilocytic histologic type, diagnosis after 1984, longer symptom duration, younger age, minimal surgical extent, and postoperative radiotherapy predicted better outcome. Conclusion: The results of our study have shown that histologic type is the most important prognostic variable affecting the outcome of spinal cord astrocytomas. Surgical resection was associated with shorter survival and thus remains an unproven treatment. Postoperative radiotherapy significantly improved survival for patients with infiltrative astrocytomas but not for those with pilocytic tumors

    Spinal cord injuries (SCI) lead to major disabilities affecting > 2.5 million people worldwide. Major shortcomings in clinical translation result from multiple factors, including species differences, development of moderately predictive animal models, and differences in methodologies between preclinical and clinical studies. To overcome these obstacles, we first conducted a comparative neuroanatomical analysis of the spinal cord between mice, Microcebus murinus (a nonhuman primate), and humans. Next, we developed and characterized a new model of lateral spinal cord hemisection in M. murinus. Over a 3-month period after SCI, we carried out a detailed, longitudinal, behavioral follow-up associated with in vivo magnetic resonance imaging ( 1 H-MRI) monitoring. Then, we compared lesion extension and tissue alteration using 3 methods: in vivo 1 H-MRI, ex vivo 1 H-MRI, and classical histology. The general organization and glial cell distribution/morphology in the spinal cord of M. murinus closely resembles that of humans. Animals assessed at different stages following lateral hemisection of the spinal cord presented specific motor deficits and spinal cord tissue alterations. We also found a close correlation between 1 H-MRI signal and microglia reactivity and/or associated post-trauma phenomena. Spinal cord hemisection in M. murinus provides a reliable new nonhuman primate model that can be used to promote translational research on SCI and represents a novel and more affordable alternative to larger primates.

    A retrospective multicenter study. Routine cervical spine surgeries are typically associated with low complication rates, but serious complications can occur. Intraoperative death is a very rare complication and there is no literature on its incidence. The purpose of this study was to determine the intraoperative mortality rates and associated risk factors in patients undergoing cervical spine surgery. Twenty-one surgical centers from the AOSpine North America Clinical Research Network participated in the study. Medical records of patients who received cervical spine surgery from January 1, 2005, to December 31, 2011, were reviewed to identify occurrence of intraoperative death. A total of 258 patients across 21 centers met the inclusion criteria. Most of the surgeries were done using the anterior approach (53.9%), followed by posterior (39.1%) and circumferential (7%). Average patient age was 57.1 ± 13.2 years, and there were more male patients (54.7% male and 45.3% female). There was no case of intraoperative death. Death during cervical spine surgery is a very rare complication. In our multicenter study, there was a 0% mortality rate. Using an adequate surgical approach for patient diagnosis and comorbidities may be the reason how the occurrence of this catastrophic adverse event was prevented in our patient population.

    Full Text Available Antibiotics are always considered for surgical site infection (SSI in adolescent idiopathic scoliosis (AIS surgery. However, the use of antibiotics often causes the antibiotic resistance of pathogens and side effects. Thus, it is necessary to explore natural products as drug candidates. Chitin Oligosaccharide (COS has anti-inflammation and anti-bacteria functions. The effects of COS on surgical infection in AIS surgery were investigated. A total of 312 AIS patients were evenly and randomly assigned into control group (CG, each patient took one-gram alternative Azithromycin/Erythromycin/Cloxacillin/Aztreonam/Ceftazidime or combined daily, experiment group (EG, each patient took 20 mg COS and half-dose antibiotics daily, and placebo group (PG, each patient took 20 mg placebo and half-dose antibiotics daily. The average follow-up was one month, and infection severity and side effects were analyzed. The effects of COS on isolated pathogens were analyzed. SSI rates were 2%, 3% and 8% for spine wounds and 1%, 2% and 7% for iliac wound in CG, EG and PG (p < 0.05, respectively. COS reduces the side effects caused by antibiotics (p < 0.05. COS improved biochemical indexes and reduced the levels of interleukin (IL-6 and tumor necrosis factor (TNF alpha. COS reduced the antibiotics dose and antibiotics-caused side effects in AIS patients with spinal fusion surgery by improving antioxidant and anti-inflammatory activities. COS should be developed as potential adjuvant for antibiotics therapies.

    2013-07-01

    The increasing incidence of spinal metastasis, a result of improved systemic therapies for cancer, has spurred a search for an alternative method for the surgical treatment of lumbar metastases. The authors report a single-stage posterior-only approach for resecting any pathological lumbar vertebral segment and reconstructing with a medium to large expandable cage while preserving all neurological structures. The authors conducted a retrospective consecutive case review of 11 patients (5 women, 6 men) with spinal metastases treated at 1 institution with single-stage posterior-only vertebral column resection and reconstruction with an expandable cage and pedicle screw fixation. For all patients, the indications for operative intervention were spinal cord compression, cauda equina compression, and/or spinal instability. Neurological status was classified according to the American Spinal Injury Association impairment scale, and functional outcomes were analyzed by using a visual analog scale for pain. For all patients, a circumferential vertebral column resection was achieved, and full decompression was performed with a posterior-only approach. Each cage was augmented by posterior pedicle screw fixation extending 2 levels above and below the resected level. No patient required a separate anterior procedure. Average estimated blood loss and duration of each surgery were 1618 ml (range 900-4000 ml) and 6.6 hours (range 4.5-9 hours), respectively. The mean follow-up time was 14 months (range 10-24 months). The median survival time after surgery was 17.7 months. Delayed hardware failure occurred for 1 patient. Preoperatively, 2 patients had intractable pain with intact lower-extremity strength and 8 patients had severe intractable pain, lower-extremity paresis, and were unable to walk; 4 of whom regained the ability to walk after surgery. Two patients who were paraplegic before decompression recovered substantial function but remained wheelchair bound, and 2 patients

    Full Text Available Subarachnoid hemorrhage (SAH is an uncommon complication of systemic lupus erythematosus (SLE. Solitary association of fatal spinal SAH as a complication of SLE, has not been encountered much in literature although coexisting acute cerebral and spinal SAH have been associated with SLE. We present a 39-year old female with initial diagnosis of SLE eight years ago who suddenly developed a productive cough, acute abdomen and paralysis of the lower limbs. Magnetic resonance imaging of the spine revealed thoracic spinal SAH with varying degrees of thoracic spinal cord compression. The hemorrhage was total evacuated via surgery. She regained normal function of her lower limbers after the operation with no further neurological complications. One of the rare but fatal complications of SLE is solitary spinal SAH without cranial involvement. The best and most appropriate management of this kind of presentation is surgical decompression of the hematoma with total hemostasis. The cause of hemorrhage should be identified intra-operatively and treated appropriately.

    Although spinal cord stimulation (SCS) is a widely used treatment for chronic neuropathic pain secondary to spinal surgery, little is known about the underlying physiological mechanisms. The primary aim of this study is to investigate the neural substrate underlying short-term SCS by means of 1 H MR spectroscopy with short echo time, in 20 patients with failed back surgery syndrome. Marked increase of γ-aminobutyric acid (GABA) and decrease in glucose in the ipsilateral thalamus were found between baseline situation without SCS and after 9' of SCS, indicating the key role of the ipsilateral thalamus as a mediator of chronic neuropathic pain. In addition, this study also showed a progressive decrease in glucose in the ipsilateral thalamus over time, which is in line with the findings of previous studies reporting deactivation in the ipsilateral thalamic region. The observation of GABA increase and glucose decrease over time in the ipsilateral thalamus may be the causal mechanism of the pain relief due to SCS or an epiphenomenon. (orig.)

    Lumbar spondylolysis and spondylolisthesis are common spinal disorders that most of the times are incidental findings or respond favorably to conservative treatment. In a small percentage of the patients, surgical intervention becomes necessary. Because too much attention has been paid to novel surgical techniques and new modern spinal implants, some of fundamental concepts have been forgotten. Identifying that small but important number of patients with lumbar spondylolysis or spondylolisthesis who would really benefit from lumbar surgery is one of those forgotten concepts. In this paper, we have developed an algorithmic approach to determine who is a good candidate for surgery due to lumbar spondylolysis or spondylolisthesis. PMID:25558333

    Full Text Available Beyazit ZencirciKahramanmaras, TurkeyBackground: Chronic renal failure is strongly associated with poor pregnancy outcome. Women dependent on hemodialysis before conception rarely achieve a successful live birth.Case presentation: A 31-year-old multiparous Turkish woman was scheduled for cesarean section under spinal anesthesia at 37 weeks and five days’ gestation because of hemorrhage due to secondary placenta previa. Spinal anesthesia with 8 mg of hyperbaric bupivacaine was successfully performed. Invasive blood pressure, central venous pressure, and heart rate were stable during the surgery. The mother returned to regular hemodialysis on the first postoperative day.Conclusion: Pregnancy is uncommon in women with chronic renal failure requiring chronic dialysis. Rates of maternal hypertension, pre-eclampsia, anemia, and infection in the pregnant chronic dialysis patient are high. However, our findings suggest that with careful, close, and effective monitoring preoperatively and intraoperatively, spinal anesthesia can be safely performed for cesarean section in patients undergoing hemodialysis.Keywords: chronic renal failure, pregnancy, spinal anesthesia, hemodialysis, placenta previa

    Experimental study. The aim of this study is to develop a modified model of spinal cord ischemia in rabbits. Shenzhen Key Laboratory of Spine Surgery, Shenzhen, China. In total, 20 New Zealand rabbits were divided into the following four groups according to the level of ligation of bilateral lumbar arteries: (1) group A, sham group, no ligation, n=5; (2) group B, ligation of bilateral lumbar arteries at three levels (L2-L4, n=5); (3) group C, ligation of bilateral lumbar arteries at four levels (L2-L5, n=5); and (4) group D, ligation of bilateral lumbar arteries at five levels (L1-L5, n=5). The latency of motor-evoked potentials was measured intraoperatively and the modified Tarlov grades were scored, followed by a histological observation of spinal cord, on the seventh day after surgery. All 10 rabbits in Group A and Group B were electrophysiologically, neurologically and histologically normal. In Group C, moderate spinal cord ischemia injury was found in three of five rabbits: they had prolonged latency of motor-evoked potentials and neuronal karyopyknosis in the anterior horn of spinal cord, and the average Tarlov score was 4.2±0.8. In Group D, severe spinal cord ischemia injury was recorded in all the five rabbits: the latency of motor-evoked potential prolonged in one rabbit, whereas the waveform disappeared in four rabbits; loss of neurons and vacuolation of gray matter were seen in spinal cord sections, and the average Tarlov score was 0.6±0.9. Selective ligation of lumbar arteries was a modified method to induce feasible and reproducible model of spinal cord ischemia in rabbits.

    Full Text Available Traumatic spinal cord injury (SCI is a detrimental condition that causes loss of sensory and motor function in an individual. Many complex secondary injury cascades occur after SCI and they offer great potential for therapeutic targeting. In this study, we investigated the response of endogenous neural progenitor cells, astrocytes, and microglia to a localized thoracic SCI throughout the neuroaxis. Twenty-five adult female Sprague-Dawley rats underwent mild-contusion thoracic SCI (n = 9, sham surgery (n = 8, or no surgery (n = 8. Spinal cord and brain tissues were fixed and cut at six regions of the neuroaxis. Immunohistochemistry showed increased reactivity of neural progenitor cell marker nestin in the central canal at all levels of the spinal cord. Increased reactivity of astrocyte-specific marker glial fibrillary acidic protein was found only at the lesion epicenter. The number of activated microglia was significantly increased at the lesion site, and activated microglia extended to the lumbar enlargement. Phagocytic microglia and macrophages were significantly increased only at the lesion site. There were no changes in nestin, glial fibrillary acidic protein, microglia and macrophage response in the third ventricle of rats subjected to mild-contusion thoracic SCI compared to the sham surgery or no surgery. These findings indicate that neural progenitor cells, astrocytes and microglia respond differently to a localized SCI, presumably due to differences in inflammatory signaling. These different cellular responses may have implications in the way that neural progenitor cells can be manipulated for neuroregeneration after SCI. This needs to be further investigated.

    To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

    Full Text Available Gerrit Haaker, Albert Fujak Department of Orthopaedic Surgery, Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany Abstract: Spinal muscular atrophy (SMA is a hereditary neuromuscular disease of lower motor neurons that is caused by a defective "survival motor neuron" (SMN protein that is mainly associated with proximal progressive muscle weakness and atrophy. Although SMA involves a wide range of disease severity and a high mortality and morbidity rate, recent advances in multidisciplinary supportive care have enhanced quality of life and life expectancy. Active research for possible treatment options has become possible since the disease-causing gene defect was identified in 1995. Nevertheless, a causal therapy is not available at present, and therapeutic management of SMA remains challenging; the prolonged survival is increasing, especially orthopedic, respiratory and nutritive problems. This review focuses on orthopedic management of the disease, with discussion of key aspects that include scoliosis, muscular contractures, hip joint disorders, fractures, technical devices, and a comparative approach of conservative and surgical treatment. Also emphasized are associated complications including respiratory involvement, perioperative care and anesthesia, nutrition problems, and rehabilitation. The SMA disease course can be greatly improved with adequate therapy with established orthopedic procedures in a multidisciplinary therapeutic approach.

    Full Text Available The aim of this study was to assess the effect of spinal block with low dose of bupivacaine and sufentanil on patients with low cardiac output who underwent lower limb surgery. Fifteen patients who had ejection fraction less than 40% (group 1 were compared with 65 cases with ejection fraction more than 40% (group 2 in our study. Our subjects underwent spinal block with 7.5 mg hyperbaric bupivacaine 0.5% and 5 µg sufentanil. We recorded early events such as hypotension, bradycardia, vasopressor need and ST segment change in our cases. The average mean arterial pressure decreased 13% (110 mmHg to 95.7 mmHg in group 1 and 20% (160 mmHg to 128 mmHg in group 2 (P<0.001. Hypotension due to spinal anesthesia was observed in none of our subjects in both groups and none of our cases need to vasopressor support. All patients remained alert, and no ST segment changes were observed in two groups. In our study none of subjects complained of pain intraoperatively. The subjects were without complaints during the spinal anesthetic in both groups. Spinal block with low dose local anesthetic and sufentanil was a safe and effective method for lower limb surgery in patients with low ejection fraction.

    Full Text Available Charcot's spine is a long-term complication of spinal cord injury. The lesion is often localized at the caudal end of long fusion constructs and distal to the level of paraplegia. However, cases are rare and the literature relevant to the management of Charcot's arthropathy is limited. This paper reviews the clinical features, diagnosis, and surgical management of post-traumatic spinal neuroarthropathy in the current literature. We present a rare case of adjacent level Charcot's lesion of the lumbar spine in a paraplegic patient, primarily treated for traumatic spinal cord lesion 39 years before current surgery. We have performed end-to-end apposition of bone after 3 column resection of the lesion, 3D correction of the deformity, and posterior instrumentation using a four-rod construct. Although the natural course of the disease remains unclear, surgery is always favorable and remains the primary treatment modality. Posterior long-segment spinal fusion with a four-rod construct is the mainstay of treatment to prevent further morbidity. Our technique eliminated the need for more extensive anterior surgery while preserving distal motion

    Haemodilution and auto-transfusion were carried out in 103 consecutive patients having major orthopaedic surgery. The records of 99 patients were available for retrospective assessment of this technique. Fifty-six per cent of the patients did not require any homologous blood transfusion. Homologous blood transfusion was given to 44% of the patients, who used up 99 units of blood in their entire hospital stay. There was no morbidity such as transfusion reaction, infection, decrease in platelets or re-operation for bleeding associated with the procedure, although there was one death secondary to myocardial infarction. This technique offered an alternative method to reduce the use of homologous blood transfusion in major orthopaedic operations.

    OBJECTIVE Although the vertical expandable prosthetic titanium rib (VEPTR) and growing rod instrumentation (GRI) encourage spinal growth via regular lengthening, they can create different results because of their different fixation patterns and mechanisms in correcting scoliosis. Previous studies have focused comparisons on coronal plane deformity with minimal attention to the sagittal profile. In this retrospective study, the authors aimed to compare the evolution of the sagittal spinal profile in early-onset scoliosis (EOS) treated with VEPTR versus GRI. METHODS The data for 11 patients with VEPTR and 22 with GRI were reviewed. All patients had more than 2 years' follow-up with more than 2 lengthening procedures. Radiographic measurements were performed before and after the index surgery and at the latest follow-up. The complications in both groups were recorded. RESULTS Patients in both groups had similar diagnoses, age at the index surgery, and number of lengthening procedures. The changes in the major coronal Cobb angle and T1-S1 spinal height were not significantly different between the 2 groups. Compared with the GRI group, the VEPTR group had less correction in thoracic kyphosis (23% ± 12% vs 44% ± 16%, p GRI: 8° ± 5°, p = 0.569), the incidence of proximal junctional kyphosis was relatively lower in the VEPTR group (VEPTR: 18.2% vs GRI: 22.7%). No significant changes in the spinopelvic parameters were observed, while the sagittal vertical axis showed a tendency toward a neutral position in both groups. The overall complication rate was higher in the VEPTR group than in the GRI group (72.7% vs 54.5%). CONCLUSIONS The VEPTR had coronal correction and spinal growth results similar to those with GRI. In the sagittal plane, however, the VEPTR was not comparable to the GRI in controlling thoracic kyphosis. Thus, for hyperkyphotic EOS patients, GRI is recommended over VEPTR.

    Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three-column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68-year-old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side. Resect the unilateral facet joint, and retain contralateral structure integrity. Protect the spinal cord, nerve root. Clear sequestrum, necrotic tissue, abscess of paravertebral and intervertebral space. Specially designed titanium mesh cages or bone blocks were implanted into interbody. Fix both side rods and compress both sides to make the mesh cages and bone blocks tight. Reconstruct posterior column structure with allogeneic bone and autologous bone. Using this technique, the procedures of debridement, spinal cord decompression, deformity correction, bone grafting

    Infectious complications occur frequently after major abdominal surgery and have a major influence on patient outcome and hospital costs. A marker that can rule out postoperative infectious complications (PICs) could aid patient selection for safe and early hospital discharge. C-reactive protein (CRP) is a widely available, fast, and cheap marker that might be of value in detecting PIC. Present meta-analysis evaluates the diagnostic value of CRP to rule out PIC following major abdominal surgery, aiding patient selection for early discharge. A systematic literature search of Medline, PubMed, and Cochrane was performed identifying all prospective studies evaluating the diagnostic value of CRP after abdominal surgery. Meta-analysis was performed according to the PRISMA statement. Twenty-two studies were included for qualitative analysis of which 16 studies were eligible for meta-analysis, representing 2215 patients. Most studies analyzed the value of CRP in colorectal surgery (eight studies). The pooled negative predictive value (NPV) improved each day after surgery up to 90% at postoperative day (POD) 3 for a pooled CRP cutoff of 159 mg/L (range 92-200). Maximum predictive values for PICs were reached on POD 5 for a pooled CRP cutoff of 114 mg/L (range 48-150): a pooled sensitivity of 86% (95% confidence interval (CI) 79-91%), specificity of 86% (95% CI 75-92%), and a positive predictive value of 64% (95% CI 49-77%). The pooled sensitivity and specificity were significantly higher on POD 5 than on other PODs (p < 0.001). Infectious complications after major abdominal surgery are very unlikely in patients with a CRP below 159 mg/L on POD 3. This can aid patient selection for safe and early hospital discharge and prevent overuse of imaging.

    An underestimated evaluation of systemic organs in cases with spinal fractures might jeopardize the intervention for treatment and future complications with an increased morbidity and mortality are almost warranted. In the present study, a retrospective analysis of spinal fracture cases associated with systemic trauma was performed to assess surgical success. A retrospective analysis of patients with thoracolumbar fractures who were admitted to the emergency unit between September 2012 and September 2014 was used for the study. The cases were categorized according to age, sex, reason of trauma, associated trauma, neurological condition and treatment details and results were analysed using SPSS 14.0 for Windows. The most common reason of trauma is detected as falls in 101 cases (64.3%). Radiological evaluation of spinal fractures revealed a compression fracture in 106 cases (67.5%) and other fractures in 51 cases (32.5%). Surgical treatment for spinal fracture was performed in 60.5% of the cases and conservative approach was preferred in 39.5% cases. In non-compressive spinal fractures, an associated pathology like head trauma, lower extremity fracture or neurological deficit was found to be higher in incidence (p systemic condition which might be associated with decreased morbidity and mortality.
