    Surgical robotic systems have been available for almost twenty years. The first surgical robotic systems were designed as supportive systems for laparoscopic approaches in general surgery (the first procedure was a cholecystectomy in 1987). The da Vinci Robotic System is the most common system used for robotic surgery today. This system is widely used in urology, gynecology and other surgical disciplines, and recently there have been initial reports of its use in spine surgery, for transoral access and anterior approaches for lumbar inter-body fusion interventions. SpineAssist, which is widely used in spine surgery, and Renaissance Robotic Systems, which are considered the next generation of robotic systems, are now FDA approved. These robotic systems are designed for use as guidance systems in spine instrumentation, cement augmentations and biopsies. The aim is to increase surgical accuracy while reducing the intra-operative exposure to harmful radiation to the patient and operating team personnel during the intervention. We offer a review of the published literature related to the use of robotic systems in spine surgery and provide information on using robotic systems.

    Vitamin D is crucial for musculoskeletal health, maintenance, and function. Vitamin D insufficiency is common among patients undergoing spine surgery and the ideal vitamin D level for spine surgery has yet to be investigated. There is a high prevalence of hypovitaminosis D in patients with musculoskeletal pain regardless of surgical intervention. With the frequency and costs of spine surgery increasing, it is imperative that efforts are continued to reduce the impact on patients and healthcare services. Studies into vitamin D and its associations with orthopaedic surgery have yielded alarming findings with regards to the prevalence of vitamin D deficiency. Importantly, altered vitamin D status also contributes to a wide range of disease conditions. Therefore, future investigations are still essential for better understanding the relationship between vitamin D and spine surgery outcomes. Whilst further research is required to fully elucidate the extent of the effects of hypovitaminosis D has on surgical outcomes, it is strongly advisable to reduce the impacts by appropriate vitamin D supplementation of deficient and at-risk patients.

    Prospective study. Assess the contamination rates of sterile microscope drapes after spine surgery. The use of the operating microscope has become more prevalent in certain spine procedures, providing superior magnification, visualization, and illumination of the operative field. However, it may represent an additional source of bacterial contamination and increase the risk of developing a postoperative infection. This study included 25 surgical spine cases performed by a single spine surgeon that required the use of the operative microscope. Sterile culture swabs were used to obtain samples from 7 defined locations on the microscope drape after its use during the operation. The undraped technician's console was sampled in each case as a positive control, and an additional 25 microscope drapes were swabbed immediately after they were applied to the microscope to obtain negative controls. Swab samples were assessed for bacterial growth on 5% sheep blood Columbia agar plates using a semiquantitative technique. No growth was observed on any of the 25 negative control drapes. In contrast, 100% of preoperative and 96% of postoperative positive controls demonstrated obvious contamination. In the postoperative group, all 7 sites of evaluation were found to be contaminated with rates of 12% to 44%. Four of the 7 evaluated locations were found to have significant contamination rates compared with negative controls, including the shafts of the optic eyepieces on the main surgeon side (24%, P = 0.022), "forehead" portion on both the main surgeon (24%, P = 0.022) and assistant sides (28%, P = 0.010), and "overhead" portion of the drape (44%, P = 0.0002). Bacterial contamination of the operative microscope was found to be significant after spine surgery. Contamination was more common around the optic eyepieces, likely due to inadvertent touching of unsterile portions. Similarly, all regions above the eyepieces also have a propensity for contamination because of unknown contact

    Study Design Cross-sectional study. Objective To assess the current practices of spine surgeons performing ambulatory surgery in the United States. Methods An electronic survey was distributed to members of the International Society for the Advancement of Spine Surgery. Data were initially examined in a univariate manner; variables with a p value ambulatory spine surgery, and 49.1% were investors in an ambulatory surgery center. Surgeon investors in ambulatory surgery centers were more likely to perform procedures of increased complexity than noninvestors, though limited data precluded a statistical correlation. Surgeons in private practice were more likely to perform ambulatory surgery (94.3%; p = 0.0176), and nonacademic surgeons were both more likely to invest in ambulatory surgery centers (p = 0.0024) and perform surgery at least part of the time in a surgery center (p = 0.0039). Conclusions Though the numbers were too few to calculate statistical significance, there was a trend toward the performance of high-risk procedures on an ambulatory basis being undertaken by those with investment status in an ambulatory center. It is possible that this plays a role in the decision to perform these procedures in this setting versus that of a hospital, where a patient may have better access to care should a complication arise requiring emergent assessment and treatment by a physician. This decision should divest itself of financial incentives and focus entirely on patient safety.

    The main goal of improving pain and neurological deficit in the practice of spine surgery is changing for a more ambitious goal, namely to improve the overall quality of life and the future of patients through three major actions (1) preserving the vertebral anatomical structures; (2) preserving the paravertebral anatomical structures; and (3) preserving the functionality of the segment. Thus, three new concepts have emerged (a) minimal surgery; (b) minimal access surgery; and (c) motion preservation surgery. These concepts are covered in a new term, minimally invasive spine surgery (MISS) The term "MISS" is not about one or several particular surgical techniques, but a new way of thinking, a new philosophy. Although the development of minimally invasive spine surgery is recent, its application includes all spine segments and almost all the existing conditions, including deformities.Evidence-based medicine (EBM), a term coined by Alvan Feinstein in the 1960s (Feinstein A (1964) Annals of Internal Medicine 61: 564-579; Feinstein A (1964) Annals of Internal Medicine 61: 757-781; Feinstein A (1964) Annals of Internal Medicine 61: 944-965; Feinstein A (1964) Annals of Internal Medicine 61: 1162-1193.), emphasizes the possibility of combining art and science following the strict application of scientific methods in the treatment of patients (Feinstein A (1964) Annals of Internal Medicine 61: 944-965; Feinstein A (1964) Annals of Internal Medicine 61: 1162-1193.), which may represent the advantages of objectivity and rationality in the use of different treatments (Fig. 11). However, EBM has many obvious defects, especially in spine surgery it is almost impossible to develop double-blind protocols (Andersson G, Bridwell K, Danielsson A, et al (2007) Spine 32: S64-S65.). In most cases, the only evidence one can find in the literature is the lack of evidence (Resnick D (2007) Spine 32:S15-S19.), however, the lack of evidence does not mean its absence. Only then, with a

    Over the past few decades, spine disorders have become a major health concern and the number of spinal surgical procedures has been rising significantly. Several biotechnologies and biomaterials are often used in spine surgery to increase the effectiveness of the treatment. In the degenerative spine, when conservative treatment is ineffective the most recommended surgical procedure is decompression followed by spinal fusion. Success rates of spine fusion extensively rely on bone grafts peculiar properties. Autograft has been considered the gold standard to achieve a solid fusion but current research is focused on the development of new biomaterials. Osteoporosis is the main cause of vertebral compression fractures that are significantly associated with pain and disability, especially in the aging population. Vertebral augmentation is a minimally invasive approach in which cement is injected into the vertebral body to stabilize the fracture. New cements are being developed in the clinical scenario with reabsorbable properties and biomechanical features more similar to the native bone. The development of disc regeneration strategies such as nucleus pulposus restoration and annulus fibrosus repair may represent a minimally invasive procedure towards regeneration rather than fusion. Therefore, biomaterials and tissue engineering are fields of growing interest among both surgeons and manufacturing companies, with a major involvement in spine surgery. This review discusses current and novel biotechnologies and biomaterial used in spine surgery employing fusion, augmentation and regeneration.

    Study Design Retrospective evaluation of prospectively collected data. Objective To evaluate infection rates following intrawound vancomycin powder application during spine tumor surgery. Methods Patients ≥18 years old undergoing spine tumor surgery and receiving intrawound vancomycin powder at a single center between January 2008 and January 2015 were enrolled. Patient demographics (age, sex, body mass index [BMI]), tumor type (metastatic, primary) and location, surgical data (estimated blood loss [EBL], levels fused, type of decompression, length of surgery and hospitalization, discharge status from hospital), radiation therapy use, and infection rates (surgery to a minimum of 30 days postoperative) were evaluated. Results Forty patients (46 procedures) undergoing spine tumor surgery and intrawound vancomycin powder application were identified. Five were excluded because of death less than 30 days postoperatively, and 35 patients (41 procedures) were enrolled: 11 women and 24 men with an average age of 61.4 years (range 19 to 92) and average BMI of 27.3 (range 17.4 to 36.8). Three cases were primary spine tumors. Five were hematologic malignancies, and 27 were metastatic cancers. Twenty-one tumors were in the thoracic spine, 12 in the lumbar spine, and 8 in the cervical spine. Average EBL was 899 mL (range 25 to 3,500), average length of surgery was 241 minutes (range 78 to 495), and average hospital stay was 15.1 days (range 3 to 49). Two culture-proven infections (Staphylococcus aureus, Enterobacter cloacae) were noted in 41 procedures (4.9%). Ten patients (28.6%) had preoperative radiation only; 14 (40%) had postoperative radiation only, 5 (14.3%) had both preoperative and postoperative radiation, and 6 (17.1%) had no radiation. There were no associations between radiation treatment and postsurgical infections (p = 0.19). Conclusion In this first study evaluating intrawound vancomycin powder for spine tumor surgery, we report an infection rate

    Perioperative visual loss (POVL) is an uncommon, but devastating complication that remains primarily associated with spine and cardiac surgery. The incidence and mechanisms of visual loss after surgery remain difficult to determine. According to the American Society of Anesthesiologists Postoperative Visual Loss Registry, the most common causes of POVL in spine procedures are the two different forms of ischemic optic neuropathy: anterior ischemic optic neuropathy and posterior ischemic optic neuropathy, accounting for 89% of the cases. Retinal ischemia, cortical blindness, and posterior reversible encephalopathy are also observed, but in a small minority of cases. A recent multicenter case control study has identified risk factors associated with ischemic optic neuropathy for patients undergoing prone spinal fusion surgery. These include obesity, male sex, Wilson frame use, longer anesthetic duration, greater estimated blood loss, and decreased percent colloid administration. These risk factors are thought to contribute to the elevation of venous pressure and interstitial edema, resulting in damage to the optic nerve by compression of the vessels that feed the optic nerve, venous infarction or direct mechanical compression. This review will expand on these findings as well as the recently updated American Society of Anesthesiologists practice advisory on POVL. There are no effective treatment options for POVL and the diagnosis is often irreversible, so efforts must focus on prevention and risk factor modification. The role of crystalloids versus colloids and the use of α-2 agonists to decrease intraocular pressure during prone spine surgery will also be discussed as a potential preventative strategy.

    Study Design Historical controlled trial. Purpose To clarify the usefulness of cryotherapy after spine surgery. Overview of Literature Cryotherapy has generally been performed subsequent to surgery on joints and in this application its clinical effects are well understood. However, cryotherapy has yet to be used following spine surgery. Its clinical efficacy in this context is unknown. Methods Thirty six patients had undergone one level microendoscopic surgery. Sixteen were enrolled into the cooling group, with the remaining 20 making up the no postoperative cryotherapy control group. Cryotherapy was performed at 5℃ using an icing system. A silicone balloon catheter with a thermo sensor on the tip was placed in the surgical wound. The temperature in the wound was recorded every 30 minutes until the next morning. The relationship between the depth of the sensor and the temperature in the wound were investigated using simple linear regression analysis. Laboratory data, visual analogue scale (VAS) for wound pain and postoperative bleeding were investigated. Results The mean temperature in the surgical wound was 37.0 in the control group and 35.0℃ in the cooling group (p<0.001). There was a positive correlation between the depth of the thermo sensor and the temperature in the wound in the cooling group (y=0.91x+30.2, r=0.67, p=0.004). There were no significant differences between the groups in terms of laboratory data, VAS or postoperative bleeding. Conclusions The temperature in the wound was decreased significantly by spinal surgery cryotherapy. PMID:25558317

    The presence of postoperative visual loss is a well-known complication, and described in various reports, its low incidence (0.028-0.2%) makes it extremely rare. Two main causes have been determined: Posterior Ischemic Optic Neuropathy and central Retinal Artery Oclusion. The following is a case report of a 52-year-old patient that presented visual loss after elective spine surgery that had no complications that could initially explain this complication. Studies were performed and evaluations by ophthalmologists determined that the cause of Posterior Ischemic Optic Neuropathy due to multiple risk factors that the patient had previously and during the surgery. After 3 year follow-up the patient still has total visual loss and no other complications were reported.

    We are developing an augmented reality (AR) image guidance system in which information derived from medical images is overlaid onto a video view of the patient. The centerpiece of the system is a head-mounted display custom fitted with two miniature color video cameras that capture the stereo view of the scene. Medical graphics is overlaid onto the video view and appears firmly anchored in the scene, without perceivable time lag or jitter. We have been testing the system for different clinical applications. In this paper we discuss minimally invasive thoracoscopic spine surgery as a promising new orthopedic application. In the standard approach, the thoracoscope - a rigid endoscope - provides visual feedback for the minimally invasive procedure of removing a damaged disc and fusing the two neighboring vertebrae. The navigation challenges are twofold. From a global perspective, the correct vertebrae on the spine have to be located with the inserted instruments. From a local perspective, the actual spine procedure has to be performed precisely. Visual feedback from the thoracoscope provides only limited support for both of these tasks. In the augmented reality approach, we give the surgeon additional anatomical context for the navigation. Before the surgery, we derive a model of the patient's anatomy from a CT scan, and during surgery we track the location of the surgical instruments in relation to patient and model. With this information, we can help the surgeon in both the global and local navigation, providing a global map and 3D information beyond the local 2D view of the thoracoscope. Augmented reality visualization is a particularly intuitive method of displaying this information to the surgeon. To adapt our augmented reality system to this application, we had to add an external optical tracking system, which works now in combination with our head-mounted tracking camera. The surgeon's feedback to the initial phantom experiments is very positive.

    Spine surgery is associated with a significant risk of postoperative pulmonary embolism (PE) and/or deep vein thrombosis (DVT). The goal of this study was to determine which symptoms and risk factors were associated with spiral CT scans positive for PE and/or DVT in the postoperative spine surgery patient. We conducted a retrospective review of all spine patients who underwent a postoperative CT to rule out PE during the period of March 2004-February 2006. The type of surgical procedure, risk factors, symptoms prompting scan ordering, anticoagulation, and treatment were recorded. Logistic regression models were used to determine significant predictors of a positive CT in this patient population. Of the 3,331 patients that had spine surgery during the study period, 130 (3.9%) had a spiral CT scan to rule out PE and/or proximal DVT. Thirty-three of the 130 (25.4%) CT scans were positive for PE only, five (3.8%) for PE and DVT, and three (2.3%) for DVT only. Only 24.5% (32) patients had risk factors for thromboembolic disease, and of these, a history of PE and/or DVT was the only significant risk factor for a positive scan (p = 0.03). No presenting symptoms or demographic variables were noted to have a significant association with PE and/or DVT. The type of surgical procedure (i.e., anterior, posterior, and percutaneous) was not associated with an increased risk for PE and/or DVT. Patients who are undergoing spine surgery with a history of thromboembolic disease should be carefully monitored postoperatively and may benefit from more aggressive prophylaxis.

    Medical robotics incrementally appears compelling in nowadays surgical work. The research regarding an ideal interaction between physician and computer assistance has reached a first summit with the implementation of commercially available robots (Intuitive Surgical's® da Vinci®). Moreover, neurosurgery--and herein spine surgery--seems an ideal candidate for computer assisted surgery. After the adoption of pure navigational support from brain surgery to spine surgery a meanwhile commercially available miniature robot (Mazor Surgical Technologies' The Spine Assist®) assists in drilling thoracic and lumbar pedicle screws. Pilot studies on efficacy, implementation into neurosurgical operating room work flow proved the accuracy of the system and we shortly outline them. Current applications are promising, and future possible developments seem far beyond imagination. But still, medical robotics is in its infancy. Many of its advantages and disadvantages must be delicately sorted out as the patients safety is of highest priority. Medical robots may achieve a physician's supplement but not substitute.

    Study Design Literature review. Objective To identify and analyze the top 100 cited articles in cervical spine surgery. Methods The Thomson Reuters Web of Knowledge was searched for citations of all articles relevant to cervical spine surgery. The number of citations, authorship, year of publication, journal of publication, country of publication, and institution were recorded for each article. Results The most cited article was the classic from 1991 by Vernon and Mior that described the Neck Disability Index. The second most cited was Smith's 1958 article describing the anterior cervical diskectomy and fusion procedure. The third most cited article was Hilibrand's 1999 publication evaluating the incidence, prevalence, and radiographic progression of symptomatic adjacent segment disease following anterior cervical arthrodesis. The majority of the articles originated in the United States (65), and most were published in Spine (39). Most articles were published in the 1990s (34), and the three most common topics were cervical fusion (17), surgical complications (9), and biomechanics (9), respectively. Author Abumi had four articles in the top 100 list, and authors Goffin, Panjabi, and Hadley had three each. The Department of Orthopaedic Surgery at Hokkaido University in Sapporo, Japan, had five articles in the top 100 list. Conclusion This report identifies the top 100 articles in cervical spine surgery and acknowledges those individuals who have contributed the most to the advancement of the study of the cervical spine and the body of knowledge used to guide evidence-based clinical decision making in cervical spine surgery today.

    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.

    The aim of this study was to evaluate the effects of music therapy on anxiety, postoperative pain and physiological reactions to emotional and physical distress in patients undergoing spinal surgery. Surgery-related anxiety and pain are the greatest concern of surgical patients, especially for those undergoing major procedures. A quasi-experimental study design was conducted in a medical centre in Taiwan from April-July 2006. Sixty patients were recruited. The study group listened to selected music from the evening before surgery to the second day after surgery. The control group did not listen to music. Patients' levels of anxiety and pain were measured with visual analogue scales (VAS). Physiological measures, including heart rate, blood pressure and 24-hour urinalysis, were performed. The average age of the 60 patients was 62·18 (SD 18·76) years. The mean VAS score for degree of anxiety in the study group was 0·8-2·0, compared with 2·1-5·1 in the control group. The mean VAS score for degree of pain in the study group was 1·7-3·0, compared with 4·4-6·0 in the control group. The differences between the two groups in VAS scores for both anxiety (p = 0·018-0·001) and pain (p = 0·001) were statistically significant. One hour after surgery, the mean blood pressure was significantly lower in the study group than in the control group (p = 0·014), but no significant differences were found between the two groups in urine cortisol (p = 0·145-0·495), norepinephrine (p = 0·228-0·626) or epinephrine values (p = 0·074-0·619). Music therapy has some positive effects on levels of anxiety and pain in patients undergoing spinal surgery. Complementary music therapy can alleviate pain and anxiety in patients before and after spinal surgery. © 2011 Blackwell Publishing Ltd.

  1. Characteristics of Hemorrhagic Stroke following Spine and Joint Surgeries

    2017-01-01

    Hemorrhagic stroke can occur after spine and joint surgeries such as laminectomy, lumbar spinal fusion, tumor resection, and total joint arthroplasty. Although this kind of stroke rarely happens, it may cause severe consequences and high mortality rates. Typical clinical symptoms of hemorrhagic stroke after spine and joint surgeries include headache, vomiting, consciousness disturbance, and mental disorders. It can happen several hours after surgeries. Most bleeding sites are located in cerebellar hemisphere and temporal lobe. A cerebrospinal fluid (CSF) leakage caused by surgeries may be the key to intracranial hemorrhages happening. Early diagnosis and treatments are very important for patients to prevent the further progression of intracranial hemorrhages. Several patients need a hematoma evacuation and their prognosis is not optimistic. PMID:28164124

    Full Text Available Introduction: Hospital patient databases are typically used by administrative staff to estimate loss-profit ratios and to help with the allocation of hospital resources. These databases can also be very useful in following rehospitalization. This paper studies the recurrence of spine surgery patients in our hospital population based on administrative data analysis. Methods: Hospital data on 4,958 spine surgery patients operated between 2002 and 2009 were retrospectively reviewed. After sorting the cohort per ascending discharge date, the patient official name, consisting of first, middle and last names, was used as the variable determining duplicate cases in the SPSS statistical program, designating the first case in each group as primary. Yearly recurrence rate and change in procedure distribution were studied. In addition, hospital charges and length of stay were compared using the Wilcoxon-Mann-Whitney test. Results: Of 4,958 spine surgery patients 364 (7.3% were categorized as duplicate cases by SPSS. The number of primary cases from which duplicate cases emerged was 327 meaning that some patients had more than two spine surgeries. Among primary patients (N=327 the percentage of excision of intervertebral disk procedures was 33.3% and decreased to 15.1% in recurrent admissions of the same patients (N=364. This decrease was compensated by an increase in lumbar fusion procedures. On the other hand, the rate of cervical fusion remained the same. The difference in hospital charges between primary and duplicate patients was $2,234 for diskectomy, $6,319 for anterior cervical fusion, $8,942 for lumbar fusion – lateral technique, and $12,525 for lumbar fusion – posterior technique. Recurrent patients also stayed longer in hospital, up to 0.9 day in lumbar fusion – posterior technique patients. Conclusion: Spine surgery is associated with an increasing possibility of additional spine surgery with rising invasiveness and cost.

    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.

    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.

    Full Text Available It is now well established that psychosocial factors can adversely impact the outcome of spine surgery. This article discusses in detail one such recently-identified “risk” factor: demoralization. Several studies conducted by the author indicate that demoralization, an emotional construct distinct from depression, is associated with poorer pain reduction, less functional improvement and decreased satisfaction among spine surgery patients. However, there are indications that the adverse impact of risk factors such as demoralization can be mitigated by psychosocial “maximizing” factors—characteristics that propel the patient towards positive surgical results. One of these maximizing factors, patient activation, is discussed in depth. The patient activation measure (PAM, an inventory assessing the extent to which patients are active and engaged in their health care, is associated not only with improved spine surgery results, but with better outcomes across a broad range of medical conditions. Other maximizing factors are discussed in this article. The author concludes that the past research focus on psychosocial risk factors has limited the value of presurgical psychological screening, and that future research, as well as clinical assessment, should recognize that the importance of evaluating patients’ strengths as well as their vulnerabilities.

    Full Text Available OBJECTIVE Lumbar spinal surgeries have been performed with either spinal or general anaesthesia. In this study, we aimed to evaluate the superiority of either spinal or general anaesthesia on lumbar spine surgery. METHODS After approval of institutional ethical committee, we retrospectively analysed 270 patients (ASA I and II undergoing surgery of lumbar spine from 2009 to 2015 by one surgeon. Of these 150 patients underwent general anaesthesia with controlled ventilation, 120 patients were offered spinal anaesthesia with conscious sedation. Patient records were reviewed to obtain demographic features, type of anaesthesia, baseline heart rate, mean arterial pressure, intraoperative maximum heart rate, mean arterial pressure, duration of surgery, amount of intravenous fluids, intraoperative blood loss, incidence of perioperative complications such as bleeding, nausea, vomiting, hypotension, bradycardia, and postoperative analgesic consumption. RESULTS Patient characteristics including baseline/intraoperative mean arterial pressure and heart rate values did not differ between groups. However, the spinal anaesthesia group experienced significantly shorter durations in the operating room and had a lower incidence of nausea, vomiting. Analgesic consumptions in general anaesthesia group was significantly higher than in spinal anaesthesia group. CONCLUSION The present study revealed that spinal anaesthesia is a safe and effective alternative to general anaesthesia for patients undergoing single level or two level lumbar laminectomy, discectomy, or even instrumentation below L2 level and has the advantage of decreased nausea, antiemetic, analgesic requirements, and fewer complications. It also ensures better postoperative recovery when compared to general anaesthesia

    Cervical spine alignment interests appeared recently and relationships between the pelvis and the cervical spine have been reported but remain unclear. In this study, postoperative changes for cranial, cervical, lumbar and sagittal balance parameters have been measured in adult scoliosis surgery without major sagittal malalignment to appreciate the adaptation of the cervical spine. Twenty-nine consecutive patients with a surgical adult degenerative scoliosis treated with a T8-T11 to iliac fusion without PSO or multiple Ponte's osteotomies had preoperative and postoperative full spine EOS radiographies to measure spino-pelvic parameters. Correlation analysis between the different parameters was performed. Lower cervical, lordosis, lumbar lordosis and thoracic kyphosis were increased in postoperative as no changes were observed for upper cervical lordosis. C1-C7 CL highly correlated (0.85 in preoperative and 0.87 in postoperative) with C7 slope, which highly correlated itself with global balance parameters (0.74 in preoperative and 0.71 in postoperative for CAM-PL) underlining the relationship between cervical spine alignment and global malalignment. Modifications of lower CL are observed, as upper CL remains constant. If no correlation was found for LL, TK and CL changes, CL appears to be highly correlated with C7 slope, which highly correlated itself with sagittal global balance parameters. C7 slope appears as a base for CL influenced by the spine global alignment.

    There is a high prevalence of hypovitaminosis D in patients with back pain regardless of whether or not they require surgical intervention. Furthermore, the risk of hypovitaminosis D is not limited to individuals with traditional clinical risk factors. Vitamin D plays an essential role in bone formation, maintenance, and remodeling, as well as muscle function. Published data indicate that hypovitaminosis D could adversely affect bone formation and muscle function in multiple ways. The literature contains numerous reports of myopathy and/or musculoskeletal pain associated with hypovitaminosis D. In terms of spinal fusion outcomes, a patient may have a significant decrease in pain and the presence of de novo bone on an X-ray, yet their functional ability may remain severely limited. Hypovitaminosis D may be a contributing factor to the persistent postoperative pain experienced by these patients. Indeed, hypovitaminosis D is not asymptomatic, and symptoms can manifest themselves independent of the musculoskeletal pathological changes associated with conditions like osteomalacia. It appears that vitamin D status is routinely overlooked, and there is a need to raise awareness about its importance among all healthcare practitioners who treat spine patients.

    Full Text Available We describe an effective surgical technique in primary repair of the spinal dura during minimally invasive spine surgery (MISS. Objective. Minimally invasive spine surgery includes the treatment of intradural lesions, and proper closure of the dura is necessary. However, primary dural closure can be difficult due to the restricted space of MIS retractors and the availability of appropriate surgical instrumentation. Methods. We describe the use of a needle already used in the pediatric neurosurgical arena that can facilitate easier and safer closure of spinal dura through MISS retractors in two illustrative intradural cases. Results and Discussion. The primary dural closure technique is described and patient demographics are included. The instruments specifically used for the intradural closure through MIS retractor systems include (1 4-0 Surgilon braided nylon (Covidien, Dublin, Ireland with a CV-20 taper 1/2 circle, 10 mm diameter needle; (2 Scanlan (Saint Paul, MN, USA dura closure set. Conclusion. Successful primary dural repair can be performed on primary and incidental durotomies during minimally invasive spinal surgery. We describe the novel use of a 10 mm diameter needle to help surgeons safely and efficiently close the dura with more ease than previously described.

    Few data are available concerning clinical outcomes in patients with Parkinson disease who undergo elective thoracolumbar spine fusion surgery. The goal of this study is to elucidate complication and revision rates after posterior thoracolumbar fusion surgery in patients with Parkinson disease, with a focus on how Parkinson disease modifies these rates. The PearlDiver database (2005-2012) was queried for patients who underwent posterior approach thoracolumbar fusion from 2006 to 2011. Cohorts of patients with a previous diagnosis of Parkinson disease (n = 4816) and without (n = 280,702) were compared. Multivariate analysis that included various comorbidities and demographics was used to calculate effects of Parkinson disease on development of postoperative infection and major medical complications within 90 days and revision surgery within 1 year. For analyses, significance was set at P Parkinson disease was significantly associated with an increased risk for medical complications (adjusted odds ratio, 1.22; 95% confidence interval, 1.11-1.34; P Parkinson disease are more likely to require revision surgery and have higher rates of adverse medical events postoperatively. Patients with Parkinson disease should be appropriately selected to ensure favorable clinical outcomes. Copyright © 2016. Published by Elsevier Inc.

    This is the first reported series looking specifically at factors associated with deep surgical site infections (SSI) following pediatric cervical spine surgery. To identify risk factors present in pediatric patients who are at risk for SSI following cervical spine surgery. Level of evidence: level IV-retrospective case series. To date there are no studies regarding SSI in pediatric cervical spine surgery and thus no benchmark data or risk factors have been identified. Patients with acute deep SSIs occurring within 90 days of the index operation were identified. Patient and surgical characteristics were analyzed for possible predictors of SSI outcome using penalized likelihood logistic regression analysis. Characteristics analyzed included: age, diagnosis, comorbidity, levels fused, approach, implants used, allograft, halo, body mass index, revision, antibiotic dosing, and occipital plating. A total of 112 patients were included in the study at a mean age of 12.5 years (2 to 18 y). Comorbidities were present in 51 (46%) patients, 15 patients had a documented connective tissue disorder (CTD). The mean number of levels fused was 3.7 (2 to 7) and mean number of screws was 4.4 (2 to 11). Allograft was used alone in 48 patients, occipital plating in 28 patients, and a halo in 39 patients. Deep SSI occurred in 3 patients: two of which had a CTD (1 Trisomy 21, 1 Ehlers-Danlos) and 1 patient with postradiation cervical kyphosis. All were gram-positive infections requiring return to operating room with prolonged IV antibiotics. All patients recovered and fused with spinal implant retention. The incidence of deep SSI was 2.7%. It was determined that a CTD was the only significant predictor of SSI. Subjects with a CTD had 12 times the odds of SSI [odds ratio=12 (1.5, 137.0); P=0.02]. In our series of pediatric patients the incidence of a deep SSI was 2.7%. The only predictor of SSI was the presence of a CTD.

    Abstract Background: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy and safety of pregabalin for pain management following spine surgery. Methods: In September 2016, a systematic computer-based search was conducted in PubMed, EMBASE, Web of Science, and Cochrane Database of Systematic Reviews. RCTs of patients prepared for spine surgery that compared pregabalin with placebo were retrieved. The primary endpoint was the VAS score with rest or mobilization at 12 hours, 24 hours, and 48 hours and cumulative morphine consumption at 24 hours and 48 hours. The secondary outcomes were complications of nausea, sedation, dizziness, headache, and visual disturbances. After testing for publication bias and heterogeneity between studies, data were aggregated for random-effects models when necessary. Results: Ten clinical studies with 535 patients (pregabalin group = 294, control group = 241) were included in the meta-analysis. Pregabalin was associated with reduced pain scores at 12 hours, 24 hours, and 48 hours, corresponding to a reduction of 1.91 points (95% CI, –4.07 to 0.24 point) at 12 hours, 2.66 points (95% CI, –4.51 to –0.81 point) at 24 hours, and 4.33 points (95% confidence interval, –6.38 to –2.99 point) at 48 hours on a 100-point numeric rating scale. There was no significant difference between VAS scores with mobilization at 12 hours, 24 hours, or 48 hours. Similarly, pregabalin was associated with a reduction in cumulative morphine consumption at 24 hours (–7.07, 95% CI –9.84, –4.30) and 48 hours (–6.52, 95% CI –7.78, –5.25, P = 0.000). Furthermore, pregabalin can reduce the occurrence of nausea (RR 0.57, 95% CI 0.41, 0.79, P = 0.001, number needed to treat = 8.4). There were no significant differences in the occurrence of sedation, dizziness, headache, or visual disturbances. Conclusions: Preoperative use of pregabalin was

    We report a very rare case of negative pressure pulmonary edema (NPPE) that occurred immediately after anterior cervical discectomy and fusion (ACDF). The patient was a 25-year-old man who sustained a facet fracture-dislocation of C5 during a traffic accident. After ACDF, he developed NPPE and needed mechanical ventilation. Fortunately, he recovered fully within 24 hours. NPPE is a rare postoperative complication that may occur after cervical spine surgery. The aims of this report are to present information regarding the diagnosis and emergent treatment of NPPE, and to review the previous literature regarding this serious complication. PMID:25558327

    AIM To investigate the microvascular (skeletal muscle tissue oxygenation; SmO2) response to transfusion in patients undergoing elective complex spine surgery. METHODS After IRB approval and written informed consent, 20 patients aged 18 to 85 years of age undergoing > 3 level anterior and posterior spine fusion surgery were enrolled in the study. Patients were followed throughout the operative procedure, and for 12 h postoperatively. In addition to standard American Society of Anesthesiologists monitors, invasive measurements including central venous pressure, continual analysis of stroke volume (SV), cardiac output (CO), cardiac index (CI), and stroke volume variability (SVV) was performed. To measure skeletal muscle oxygen saturation (SmO2) during the study period, a non-invasive adhesive skin sensor based on Near Infrared Spectroscopy was placed over the deltoid muscle for continuous recording of optical spectra. All administration of fluids and blood products followed standard procedures at the Hospital for Special Surgery, without deviation from usual standards of care at the discretion of the Attending Anesthesiologist based on individual patient comorbidities, hemodynamic status, and laboratory data. Time stamps were collected for administration of colloids and blood products, to allow for analysis of SmO2 immediately before, during, and after administration of these fluids, and to allow for analysis of hemodynamic data around the same time points. Hemodynamic and oxygenation variables were collected continuously throughout the surgery, including heart rate, blood pressure, mean arterial pressure, SV, CO, CI, SVV, and SmO2. Bivariate analyses were conducted to examine the potential associations between the outcome of interest, SmO2, and each hemodynamic parameter measured using Pearson’s correlation coefficient, both for the overall cohort and within-patients individually. The association between receipt of packed red blood cells and SmO2 was performed by

    OBJECTIVE Depression is the most prevalent affective disorder in the US, and patients with spinal deformity are at increased risk. Postoperative delirium has been associated with inferior surgical outcomes, including morbidity and mortality. The relationship between depression and postoperative delirium in patients undergoing spine surgery is relatively unknown. The aim of this study was to determine if depression is an independent risk factor for the development of postoperative delirium in patients undergoing decompression and fusion for deformity. METHODS The medical records of 923 adult patients (age ≥ 18 years) undergoing elective spine surgery at a single major academic institution from 2005 through 2015 were reviewed. Of these patients, 255 (27.6%) patients had been diagnosed with depression by a board-certified psychiatrist and constituted the Depression group; the remaining 668 patients constituted the No-Depression group. Patient demographics, comorbidities, and intra- and postoperative complication rates were collected for each patient and compared between groups. The primary outcome investigated in this study was rate of postoperative delirium, according to DSM-V criteria, during initial hospital stay after surgery. The association between depression and postoperative delirium rate was assessed via multivariate logistic regression analysis. RESULTS Patient demographics and comorbidities other than depression were similar in the 2 groups. In the Depression group, 85.1% of the patients were taking an antidepressant prior to surgery. There were no significant between-group differences in intraoperative variables and rates of complications other than delirium. Postoperative complication rates were also similar between the cohorts, including rates of urinary tract infection, fever, deep and superficial surgical site infection, pulmonary embolism, deep vein thrombosis, urinary retention, and proportion of patients transferred to the intensive care unit.

    Perioperative vision loss is a rare complication of orthopaedic surgery and has been documented after spine, knee, hip, and shoulder procedures. It is associated with several ophthalmologic diagnoses, most commonly ischemic optic neuropathy. Although the pathophysiology remains unclear, current evidence suggests that systemic hemodynamic compromise and altered balance of intraocular perfusion contribute to the development of ischemic optic neuropathy. Although vision recovery has been reported, the prognosis of perioperative vision loss is poor, and no proven effective treatment is available. Perioperative vision loss is unpredictable and can occur in healthy patients. Associated risk factors include pediatric or elderly age, male sex, obesity, anemia, hypotension or hypertension, perioperative blood loss, prolonged surgical time, and prone positioning. Preventive strategies include avoiding direct pressure to the eye, elevating the head, optimizing perioperative hemodynamic status, and minimizing surgical time with staged surgical procedures as appropriate.

  1. The "fixateur interne" as a versatile implant for spine surgery.

    Science.gov (United States)

    Dick, W

    1987-11-01

    The "fixateur interne" is a new device for posterior spine surgery. It consists of long Schanz screws which are inserted from a posterior approach through the pedicles into the vertebral bodies, and of connecting threaded longitudinal rods, carrying mobile clamps which can be fixed in every position by nuts. The long leverarms of the Schanz screws facilitate manual reduction. They are removed at the end of operation. As the device is stable against flexion and rotation by itself, it does not act on the four-point bending principle. Thus, the fixation can be restricted to the immediately adjacent vertebrae of a lesion, leaving the rest of the spine mobile. In fracture treatment instrumentation is combined with a direct repair of the anterior loss of bone stock by a transpedicular bone grafting procedure from the same dorsal approach. This report presents and discusses 183 instrumentations in fresh fractures, posttraumatic deformities, degenerative diseases, tumors, and severe spondylolistheses. The main advantage is the short fixation area and the ease of after treatment.

    Introduction Multilevel cervical myelopathy without surgical treatment is generally poor in the neurological deficit without surgical decompression. The two main surgical strategies used for the treatment of multilevel cervical myelopathy are anterior decompression via anterior corpectomy or posterior decompression via laminctomy/laminoplasty. Presentation of case We present the case of a 62 year-old lady, harboring rheumatoid artritis (RA) with gait disturbances, pain, and weakness in both arms. A C5 and C6 somatectomy, C4–C7 discectomy and, instrumentation and fusion with telescopic distractor “piston like”, anterior plate and expandable screws were performed. Two days later the patient complained dysfagia, and a cervical X-ray showed hardware dislocation. So a C4 somatectomy, telescopic extension of the construct up to C3 with expandible screws was performed. After one week the patient complained again soft dysfagia. New cervical X-ray showed the pull out of the cranial screws (C3). So the third surgery “one stage combined” an anterior decompression with fusion along with posterior instrumentation, and fusion was performed. Discussion There is a considerable controversy over which surgical approach will receive the best clinical outcome for the minimum cost in the compressive cervical myelopathy. However, the most important factors in patient selection for a particular procedure are the clinical symptoms and the radiographic alignment of the spine. the goals of surgery for cervical multilevel stenosis include the restoration of height, alignment, and stability. Conclusion We stress the importance of a careful patients selection, and invocated still the importance for 360° cervical fixation. PMID:25734320

    Full Text Available Objectives:To evaluate the accuracy and the operative complications of implanting pedicle screws in the thoracic and lumbar spine, using computer-assisted surgery compared to the implantation technique using fluoroscopy.Methods:A retrospective study was conducted at the Hospital Universitário Cajuru PUC-PR from January 2000 to January 2009. Two groups of patients undergoing implant pedicle screws were analyzed (n=80. Group I received implant pedicle screws through fluoroscopy technique and group II, through neuronavigation technique. The accuracy of positioning of pedicle screws was evaluated using rating scales.Results:The accuracy was higher in group II, where 77.5% of the screws were correctly positioned, whereas there were only 28.5% in group I (p=0.001. There was a reduction of 95% (CI: 80-97% in the risk of screws misplacement in group II. The average operation time was 312.2±78.1 minutes in group I and 270.3±41.4 in group II (p=0.004. Blood transfusion was needed in 28 patients in group I and 10 patients in group II (p=0.005, resulting in 64% risk reduction of blood transfusion in group II. Eight patients in group I underwent revision surgery whereas only one patient in the group II, that is, 75% of surgical revision risk reduction.Conclusion:The implantation technique of pedicle screws using neuronavigation is a more accurate method and has less operative complications compared with the technique that uses fluoroscopy.

    Full Text Available Background: Surgical treatment of adult lumbar spinal disorders is associated with a substantial risk of intraoperative and perioperative complications. There is no clearly defined medical literature on complication in lumbar spine surgery. Purpose of the study is to retrospectively evaluate intraoperative and perioperative complications who underwent various lumbar surgical procedures and to study the possible predisposing role of advanced age in increasing this rate. Materials and Methods: From 2007 to 2011 the number and type of complications were recorded and both univariate, (considering the patients′ age and a multivariate statistical analysis was conducted in order to establish a possible predisposing role. 133 were lumbar disc hernia treated with microdiscetomy, 88 were lumbar stenosis, treated in 36 cases with only decompression, 52 with decompression and instrumentation with a maximum of 2 levels. 26 patients showed a lumbar fracture treated with percutaneous or open screw fixation. 12 showed a scoliotic or kyphotic deformity treated with decompression, fusion and osteotomies with a maximum of 7.3 levels of fusion (range 5-14. 70 were spondylolisthesis treated with 1 or more level of fusion. In 34 cases a fusion till S1 was performed. Results: Of the 338 patients who underwent surgery, 55 showed one or more complications. Type of surgical treatment ( P = 0.004, open surgical approach (open P = 0.001 and operative time ( P = 0.001 increased the relative risk (RR of complication occurrence of 2.3, 3.8 and 5.1 respectively. Major complications are more often seen in complex surgical treatment for severe deformities, in revision surgery and in anterior approaches with an occurrence of 58.3%. Age greater than 65 years, despite an increased RR of perioperative complications (1.5, does not represent a predisposing risk factor to complications ( P = 0.006. Conclusion: Surgical decision-making and exclusion of patients is not justified only

    Study Design Multivariate analysis of prospectively collected registry data Objective Using multivariate analysis, to determine significant risk factors for medical complication after cervical spine surgery. Summary of Background Data Several studies have examined the occurrence of medical complication after spine surgery. However many of these studies have been done utilizing large national databases. While these allow for analysis of thousands of patients, potentially influential co-variates are not accounted for in these retrospective studies. Furthermore, the accuracy of these retrospective data collection in these databases has been called into question. Methods The Spine End Results Registry (2003–2004) is a collection prospectively collected data on all patients who underwent spine surgery at our two institutions. Extensive demographic and medical information were prospectively recorded as described previously by Mirza et al. Complications were defined in detail a priori and were prospectively recorded for at least 2 years after surgery. We analyzed risk factors for medical complication after lumbar spine surgery using univariate and multivariate analysis. Results We analayzed data from 582 patients who met out inclusion criteria. The cumulative incidences of complication after cervical spine surgery per organ system are as follows: cardiac – 8.4%, pulmonary – 13%, gastrointestinal – 3.9%, neurological – 7.4%, hematological – 10.8% and urologic complications – 9.2%. The occurrence of cardiac or respiratory complication after cervical spine surgery was significantly associated with death within 2 years (RR 4.32, 6.43 respectively). Relative risk values with 95% confidence intervals and p values are listed individually in Tables 2 and 3. Conclusion Risk factors identified in this study can be beneficial to clinicians and patients alike when considering surgical treatment of the cervical spine.

    Background Technical advancements in spine surgery have made possible the treatment of increasingly complex pathologies with less morbidity. Time constraints in surgeons' training have made it necessary to develop new training models for spine pathology. Objective To describe the application of a novel compound, Stratathane resin ST-504 derived polymer (SRSDP), that can be injected at different spinal target locations to mimic spinal epidural, subdural extra-axial, and intra-axial pathologies for the use in advanced surgical training. Material and Methods Fresh-frozen thoracolumbar and cervical spine segments of human and sheep cadavers were used to study the model. SRSDP is initially liquid after mixing, allowing it to be injected into target areas where it expands and solidifies, mimicking the entire spectrum of spinal pathologies. Results Different polymer concentrations have been codified to vary adhesiveness, texture, spread capability, deformability, and radiologic visibility. Polymer injection was performed under fluoroscopic guidance through pathology-specific injection sites that avoided compromising the surgical approach for subsequent excision of the artificial lesion. Inflation of a balloon catheter of the desired size was used to displace stiff cadaveric neurovascular structures to mimic pathology-related mass effect. Conclusion The traditional cadaveric training models principally only allow surgeons to practice the surgical approach. The complex spine pathology simulator is a novel educational tool that in a user-friendly, low-cost fashion allows trainees to practice advanced technical skills in the removal of complex spine pathology, potentially shortening some of the aspects of the learning curve of operative skills that may otherwise take many years to acquire.

    Purpose. The purpose of our study is to evaluate the level of evidence (LOE) of spine surgery publications in the Arab countries and compare it with standard international literature in spine surgery and to determine the stand of the Arab nations academic production with that of the global one. Methods. An online search using “PubMed” and “Google Scholar” was carried out, using search terms related to spine surgery such as “Spine surgery,” “Scoliosis,” “Herniated disc.” Each article was reviewed and graded by two reviewers using Oxford Centre for Evidence-Based Medicine (OCEBM) Levels of Evidence scale. Results. We have identified 434 articles that met the inclusion criteria; 56% were level IV studies. The most common study design was case reports (42%). The number of Arab countries with publications in spine surgery was 18 countries. The country with the highest rate of publications was Egypt (26%). The quantity of the published studies increased from 151 in (2000–2008) to 283 in (2009–2015). There is statistical significance between high and low LOE articles (p = 0.0007). Conclusion. We have observed that LOE has not changed significantly over the period of 15 years and that much of the publications are of a low LOE (levels III and IV). We, herein, emphasize the need for spine surgeons in the Arab countries to conduct studies of higher LOE. PMID:28316989

    Study Design Retrospective database analysis. Objective To assess the effect glycemic control has on perioperative morbidity and mortality in patients undergoing elective degenerative lumbar spine surgery. Summary of background data Diabetes Mellitus (DM) is a prevalent disease of glucose dysregulation that has been demonstrated to increase morbidity and mortality following spine surgery. However, there is limited understanding of whether glycemic control influences surgical outcomes in DM patients undergoing lumbar spine procedures for degenerative conditions. Methods The Nationwide Inpatient Sample was analyzed from 2002 to 2011. Hospitalizations were isolated based on International Classification of Diseases Ninth Revision, Clinical Modification procedural codes for lumbar spine surgery and diagnoses codes for degenerative conditions of the lumbar spine. Patients were then classified into three cohorts: controlled diabetics, uncontrolled diabetics and non-diabetics. Patient demographic data, acute complications and hospitalization outcomes were determined for each cohort. Results A total of 403,629 (15.7%) controlled diabetics and 19,421(0.75%) uncontrolled diabetics underwent degenerative lumbar spine surgery from 2002-2011. Relative to non-diabetics, uncontrolled diabetics had significantly increased odds of cardiac complications, deep venous thrombosis and post-operative shock; additionally, uncontrolled diabetics also had an increased mean length of stay (approximately 2.5 days), greater costs (1.3-fold) and a greater risk of inpatient mortality (odds ratio=2.6, 95% confidence interval=1.5-4.8, p degenerative lumbar spine surgery leads to increased risk of acute complications and poor outcomes. Patients with uncontrolled DM, or poor glucose control, may benefit from improving glycemic control prior to surgery. PMID:24983935

    Full Text Available This was a retrospective review of a consecutive series of patients with spinal disease in year 2000, who underwent posterior fusion and instrumentation with Harrington distraction and Cotrel-Dobousset system to evaluate causes of hardware failure. Many cases of clinical failure has been observed in spinal instrumentation used in spinal disorder like spondylolisthesis, fractures, deformities, … . Thirty six cases that were operated because of spinal disorders like spondylolisthesis, fractures, deformities, …, were included in this study. Seventeen of this cases had breakage of device. Factors like age at surgery, type of instrumentation, angles before and after surgery and …, were compared in two groups of patients. The most common instrument breakage was pedicle screw breakage. Pseudoarthrosis was the main factor that was presented in failure group (P value<0.001. Other important causes were, age of patient at surgery (P value=0.04, pedicle screw placement off center in the sagittal or coronal plane of the pedicle (P value=0.04. Instrumentation loads increased significantly as a direct result of variations in surgical technique that produce pseudoarthrosis, pedicle screw placement off center in the sagittal plane of the pedicle, or using less than 6 mm diameter screw. This factor can be prevented with meticulous surgical technique and using proper devices.

    Although many children with spina bifida and associated scoliosis or dislocated hips undergo spine or hip surgery, the benefits are uncertain. The purpose was to perform an evidence-based review on the benefits and risks of surgery for dislocated hips and scoliosis in spina bifida. I performed a Medline(®) and Embase(®) search from 1950 to 2009 for Level I to Level III studies investigating the benefits and risks of surgery for scoliosis and hip dislocation in patients with spina bifida. When available, I extracted types of surgery, complication rates, functional outcomes of seating, walking, and overall physical function. All treatment recommendations received a Grade of Recommendation: Grade A (consistent Level I studies); Grade B (consistent Level II and III studies); Grade C (consistent level IV and V studies); or Grade I (insufficient or contradictory studies). Combined anterior and posterior surgery had lower rates of nonunion for scoliosis. Although there may be some benefit in seating, overall physical function measured in a different and nonstandardized fashion was not much changed and major complication rates, including nonunion and infections for scoliosis surgery, exceed 50% in several studies. For dislocated hips, the impact on walking ability appears related to contracture (not dislocation). Surgery for hip dislocation did not improve walking ability. The literature provides no guidance on the best treatment for unilateral dislocation. The benefits of scoliosis surgery are uncertain (Grade I). Spine surgery, if performed, should be anterior and posterior (Grade B). An all-pedicle approach for scoliosis surgery may be effective (Level I). Hip reduction surgery did not improve walking (Grade B) but may be appropriate in low-level unilateral dislocation (Level I).

    A feasibility study was performed to determine the efficacy of computer assistance in endoscopic spine surgery. To assess a new method for computer assistance based on image guidance during thoracoscopic or any endoscopic spine procedure. To evaluate the reproducibility, the sensitivity and the reliability of the technique first in vitro and second in clinical use. The computer-based, image-guided surgery is now a routine tool used in open spine surgery. Exposure of the anatomy of the vertebra is needed for registration. This methodology is inapplicable in endoscopic approach. Fluoroscopic-based navigation combines the technology of image-guided surgery and C-arm fluoroscopy. The navigation is based on the fluoroscopic images acquired before surgery. This technology is applicable to endoscopic surgery but the navigation is based on fluoroscopic image. The computed tomography images are not exploited. There are no published data on a technique that allows image-guided surgery based on computed tomography and magnetic resonance imaging. A laboratory study was performed on a thoracic human spine. One vertebra was marked on the right lateral side of the body with five titanium marks. A percutaneous reference frame was specifically designed to be placed in the pedicle of the same marked vertebrae. The reference frame acted as a 3D localizer and a registration tool. The spine model was scanned including the reference frame. A standard Stealth station treatment guidance platform (Medtronic, Sofamor Danek, Memphis, TN) was used for simulation. The registration was obtained using the reference frame. Twenty navigation procedure trials were done and the error was recorded based on the distance between the anatomical point and the corresponding virtual one. Registration was always possible using the stealth station and a standard spine navigational software (spine 3, Medtronic Sofamor Danek, Memphis, TN). The mean error after registration given by the computer was 0.96 mm

    Systematic review. The aim of this study was to review the techniques, indications, and outcomes of minimally invasive surgery (MIS) and separation surgery with subsequent radiosurgery in the treatment of patients with metastatic spine disease. The utilization of MIS techniques in patients with spine metastases is a growing area within spinal oncology. Separation surgery represents a novel paradigm where radiosurgery provides long-term control after tumor is surgically separated from the neural elements. PubMed, Embase, and CINAHL databases were systematically queried for literature reporting MIS techniques or separation surgery in patients with metastatic spine disease. PRISMA guidelines were followed. Of the initial 983 articles found, 29 met inclusion criteria. Twenty-five articles discussed MIS techniques and were grouped according to the primary objective: percutaneous stabilization (8), tubular retractors (4), mini-open approach (8), and thoracoscopy/endoscopy (5). The remaining 4 studies reported separation surgery. Indications were similar across all studies and included patients with instability, refractory pain, or neurologic compromise. Intraoperative variables, outcomes, and complications were similar in MIS studies compared to traditional approaches, and some MIS studies showed a statistically significant improvement in outcomes. Studies of mini-open techniques had the strongest evidence for superiority. Low-quality evidence currently exists for MIS techniques and separation surgery in the treatment of metastatic spine disease. Given the early promising results, the next iteration of research should include higher-quality studies with sufficient power, and will be able to provide higher-level evidence on the outcomes of MIS approaches and separation surgery.

    The authors' goal was to determine whether the incidence of postoperative sore throat, hoarseness, and dysphagia associated with anterior spine surgery is reduced by maintaining endotracheal tube cuff pressure (ETCP) at 20 mm Hg during the period of neck retraction. Fifty-one patients scheduled for anterior cervical spine surgery were enrolled. After intubation, ETCP was adjusted to 20 mm Hg in all patients. Following placement of neck retractors, ETCP was measured. Patients were randomized to a control (no adjustment) or treatment group (ETCP adjusted to 20 mm Hg). A blinded observer questioned the patients about the presence of sore throat, dysphagia, and hoarseness at 1 hour, 24 hours, and 1 week postoperatively. No differences between groups at 1 hour postoperatively were demonstrated. At 24 hours, 51% of patients in the treatment group complained of sore throat compared with 74% of control patients (p predictors of postoperative throat discomfort following anterior cervical spine surgery in which neck retraction is performed: increased ETCP during neck retraction (sore throat), neck retraction time (dysphagia), and female sex (sore throat and hoarseness). The simple maneuver of decreasing ETCP to 20 mm Hg may be helpful in improving patient comfort following anterior cervical spine surgery.

    Aging frequently induces degenerative changes in the spine. Patients who suffer from lumbar degenerative disease tend to have lower back pain, neurological claudication, and neuropathy. Furthermore, incontinence may be an increasing issue as symptoms become severe. Lumbar spine fusion surgery is necessary if clinical symptoms continue to worsen or if the patient fails to respond to medication, physical therapy, or alternative treatments. However, this surgical procedure frequently induces adjacent segment disease (ASD), which is evidenced by the appearance of pathological changes in the upper and lower sections of the spinal surgical sites. In 1997, ISOBAR TTL dynamic rod stabilization was developed for application in spinal fusion surgery to prevent ASD-related complications. The device has proven effective in reducing pain in the lower back and legs, decreasing functional disability, improving quality of life, and retarding disc degeneration. However, the effectiveness of this intervention in decreasing the incidence of ASD requires further research investigation, and relevant literature and research in Taiwan is still lacking. This article discusses lumbar degenerative disease, its indications, the contraindications of lumbar spine fusion surgery using ISOBAR, and related postoperative nursing care. We hope this article provides proper and new knowledge to clinical nurses for the care of patients undergoing lumbar spine fusion surgery with ISOBAR.

    Gluteal compartment syndrome (GCS) is an extremely rare and potentially devasting disorder, most commonly caused by gluteal muscle compression in extend periods of immobilization. We report a 65-year-old obese man with hypertension, diabetes mellitus type 2 and hypercholesterolemia underwent lumbar spine surgery in knee-chest position because of degenerative lumbar stenosis. Perioperative hypotension occurred. After surgery, the patient developed increasing pain in the buttocks of both sides and oliguria with darkened urine. Stiffness, tenderness and painful swelling of patients gluteal muscles of both sides, high creatine phosphokinase level, myoglobulinuria and oliguria led to diagnosis of bilateral GCS, complicated by severe rhabdomyolysis (RM) and acute renal failure. In conclusion, obese patients with vascular risk factors and perioperative hypotension may be at risk for developing bilateral GCS and RM when performing prolonged lumbar spine surgery. Early diagnosis and treatment is important, as otherwise, the further course may be fatal.

    Full Text Available Abstract Background Independent of efficacy, information on safety of surgical procedures is essential for informed choices. We seek to develop standardized methodology for describing the safety of spinal operations and apply these methods to study lumbar surgery. We present a conceptual model for evaluating the safety of spine surgery and describe development of tools to measure principal components of this model: (1 specifying outcome by explicit criteria for adverse event definition, mode of ascertainment, cause, severity, or preventability, and (2 quantitatively measuring predictors such as patient factors, comorbidity, severity of degenerative spine disease, and invasiveness of spine surgery. Methods We created operational definitions for 176 adverse occurrences and established multiple mechanisms for reporting them. We developed new methods to quantify the severity of adverse occurrences, degeneration of lumbar spine, and invasiveness of spinal procedures. Using kappa statistics and intra-class correlation coefficients, we assessed agreement for the following: four reviewers independently coding etiology, preventability, and severity for 141 adverse occurrences, two observers coding lumbar spine degenerative changes in 10 selected cases, and two researchers coding invasiveness of surgery for 50 initial cases. Results During the first six months of prospective surveillance, rigorous daily medical record reviews identified 92.6% of the adverse occurrences we recorded, and voluntary reports by providers identified 38.5% (surgeons reported 18.3%, inpatient rounding team reported 23.1%, and conferences discussed 6.1%. Trained observers had fair agreement in classifying etiology of 141 adverse occurrences into 18 categories (kappa = 0.35, but agreement was substantial (kappa ≥ 0.61 for 4 specific categories: technical error, failure in communication, systems failure, and no error. Preventability assessment had moderate agreement (mean weighted

    2015-01-01

    Full Text Available Rheumatoid arthritis (RA is a chronic systemic inflammatory disease affecting a significant percentage of the population. The cervical spine is often affected in this disease and can present in the form of atlantoaxial instability (AAI, cranial settling (CS, or subaxial subluxation (SAS. Patients may present with symptoms and disability secondary to these entities but may also be neurologically intact. Cervical spine involvement in RA can pose a challenge to the clinician and the appropriate role of surgical intervention is controversial. The aim of this paper is to describe the pathology, pathophysiology, clinical manifestations, and diagnostic evaluation of rheumatoid arthritis in the cervical spine in order to provide a better understanding of the indications and options for surgery. Both the medical and surgical treatment options for RA have improved, so has the prognosis of the cervical spine disease. With the advent of disease modifying antirheumatic drugs (DMARDs, fewer patients are presenting with cervical spine manifestations of RA; however, those that do, now have improved surgical techniques available to them. We hope that, by reading this paper, the clinician is able to better evaluate patients with RA in the cervical spine and determine in which patients surgery is indicated.

    Full Text Available Aim. We discuss technical points, the safety, and efficacy of ultrasonic bone shaver in various spinal surgeries within our own series. Methods. Between June 2010 and January 2014, 307 patients with various spinal diseases were operated on with the use of an ultrasonic bone curette with microhook shaver (UBShaver. Patients’ data were recorded and analyzed retrospectively. The technique for the use of the device is described for each spine surgery procedure. Results. Among the 307 patients, 33 (10.7% cases had cervical disorder, 17 (5.5% thoracic disorder, 3 (0.9% foramen magnum disorder, and 254 (82.7% lumbar disorders. Various surgical techniques were performed either assisted or alone by UBShaver. The duration of the operations and the need for blood replacement were relatively low. The one-year follow-up with Neck Disability Index (NDI and Oswestry Disability Index (ODI scores were improved. We had 5 cases of dural tears (1.6% in patients with lumbar spinal disease. No neurological deficit was found in any patients. Conclusion. We recommend this device as an assistant tool in various spine surgeries and as a primary tool in foraminotomies. It is a safe device in spine surgery with very low complication rate.

    2007-01-01

    Progress in implant design and surface properties have improved long-term survival of total hip prosthesis and lowered the incidence of dislocation. New materials, particularly ceramics and metals, decrease the risk for implant loosening because they induce less particle disease than polyethylene debris. These new materials have been submitted to simulator studies before being released for clinical use. They have been used since a sufficient amount of time in clinical practice to consider them as being part of our current armamentarium. They enable the orthopaedic surgeon to tailor the optimal hip prosthesis to each patient's need, depending on his/her bone stock, activity level and life expectancy. Disk prostheses and the general concept of non fusion surgery in spine surgery seems attractive, since intervertebral fusion carries a number of drawbacks, particularly at the level of adjacent segments. However, the documented follow-up of non-fusion spine surgery is at present insufficient to consider a widespread use of these new technologies. Their own possible complications are largely unknown and they do not replace bone fusion in the most clear-cut accepted indications for spine surgery. The use of disk prostheses should therefore be strictly limited according to present knowledge.

    Full Text Available Introduction & Objective: By prevention of bleeding during spine surgery, we could provide suitable field for the surgeon and also reduce blood loss and the need for transfusion. The purpose of this study was to compare the effects of intravenous administration of propofol and isoflurane for anesthesia maintenance on the amount of blood loss and hemodynamic status during the surgery. Materials & Methods: In this clinical trial single blind study, 100 patients undergoing spinal surgery with ASA I were randomly assigned in two groups P and I; in group P we used intra-venous propofol (100-200 ?/kg/min plus nitrous oxide 50% (50 patients and in group I we applied isoflurane, (MAC 1.5-2 plus nitrous oxide 50% (50 patients for maintenance of an-esthesia. For determining and comparing blood loss in each group, total volume of blood loss during surgery was determined by weighting of blood on gausses and volume of blood in suction bottle. The amount of hemoglobin, the need for blood transfusion and satisfaction of surgeon from operative field during surgery were also assessed. Mean arterial pressure and heart rate were measured every 5 minutes intra operative and were compared in the two groups. The data was analyzed by SPSS and t-test. Results: The total volume of blood loss in propofol and isoflurane groups was 352.7± 303.5 and 450.48±321.8 ml, respectively. Total blood loss, and blood loss per min was significantly lower in the propofol group and isoflurane group (P=0.049, P=0.015. Surgeon satisfaction with bleeding of surgery field based on the Boezzart scale was higher in the propofol group. Decrease in hemoglobin concentration and hematocrit were less in the propofol group com-pared to the isoflurane group. Mean arterial pressure during surgery with the propofol group was 85.71±9.7 versus 80.25±8.04 mmHg in the isoflurane group, which was significantly lower in the isoflurane group (P=0.003.

    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.

The patient was treated with emergent external ventriculostomy following by a posterior fossa decompressive craniectomy. Cerebellar haemorrhages have to be suspected systematically when unexpected neurological signs occur after spine surgery since their rapid management lead to favourable outcomes. The present imaging findings allow us proposing that cerebellar haemorrhages result primarily from superior cerebellar venous stretching and tearing, and that cerebellar infarction and swelling occur secondarily.

    Postoperative metrics are increasingly important in determining standards of quality for physicians and hospitals. Although complications following spinal surgery have been described, procedural and patient variables have yet to be incorporated into a predictive model of adverse-event occurrence. We sought to develop a predictive model of complication occurrence after spine surgery. We used longitudinal prospective data from a national claims database and developed a predictive model incorporating complication type and frequency of occurrence following spine surgery procedures. We structured our model to assess the impact of features such as preoperative diagnosis, patient comorbidities, location in the spine, anterior versus posterior approach, whether fusion had been performed, whether instrumentation had been used, number of levels, and use of bone morphogenetic protein (BMP). We assessed a variety of adverse events. Prediction models were built using logistic regression with additive main effects and logistic regression with main effects as well as all 2 and 3-factor interactions. Least absolute shrinkage and selection operator (LASSO) regularization was used to select features. Competing approaches included boosted additive trees and the classification and regression trees (CART) algorithm. The final prediction performance was evaluated by estimating the area under a receiver operating characteristic curve (AUC) as predictions were applied to independent validation data and compared with the Charlson comorbidity score. The model was developed from 279,135 records of patients with a minimum duration of follow-up of 30 days. Preliminary assessment showed an adverse-event rate of 13.95%, well within norms reported in the literature. We used the first 80% of the records for training (to predict adverse events) and the remaining 20% of the records for validation. There was remarkable similarity among methods, with an AUC of 0.70 for predicting the occurrence of

    Cervical proprioception plays a key role in postural control, but its specific contribution is controversial. Postural impairment was shown in whiplash injuries without demonstrating the sole involvement of the cervical spine. The consequences of degenerative cervical spine diseases are underreported in posture-related scientific literature in spite of their high prevalence. No report has focused on the two different mechanisms underlying cervicobrachial pain: herniated discs and spondylosis. This study aimed to evaluate postural control of two groups of patients with degenerative cervical spine diseases with or without optokinetic stimulation before and after surgical treatment. Seventeen patients with radiculopathy were recruited and divided into two groups according to the spondylotic or discal origin of the nerve compression. All patients and a control population of 31 healthy individuals underwent a static posturographic test with 12 recordings; the first four recordings with the head in 0° position: eyes closed, eyes open without optokinetic stimulation, with clockwise and counter clockwise optokinetic stimulations. These four sensorial situations were repeated with the head rotated 30° to the left and to the right. Patients repeated these 12 recordings 6weeks postoperatively. None of the patients reported vertigo or balance disorders before or after surgery. Prior to surgery, in the eyes closed condition, the herniated disc group was more stable than the spondylosis group. After surgery, the contribution of visual input to postural control in a dynamic visual environment was reduced in both cervical spine diseases whereas in a stable visual environment visual contribution was reduced only in the spondylosis group. The relative importance of visual and proprioceptive inputs to postural control varies according to the type of pathology and surgery tends to reduce visual contribution mostly in the spondylosis group.

    A prospective study on postoperative meralgia paresthetica after posterior thoracolumbar spine surgery on the Relton-Hall frame. To assess the incidence of postoperative lateral femoral cutaneous nerve (LFCN) neuralgia and to investigate its risk factors and clinical outcomes. Postoperative meralgia paresthetica is a common complication of posterior thoracolumbar spine surgery. The injury mechanism is external compression to the LFCN near the anterior superior iliac spine in the prone position. A total of 252 patients were examined for signs of meralgia paresthetica before and after surgery. Patients with a LFCN injury were followed regularly until sensory impairment resolved. Several possible contributing factors were assessed to evaluate the correlations. Postoperative meralgia paresthetica was experienced by 60 patients (23.8%). Patients with an LFCN injury had a significantly greater body mass index (23.6 vs. 22.4 kg/m2) and a longer surgical time (3.7 vs. 3.2 hours). Overweight/obese patients had a significantly greater incidence (odds ratio, 1.83; 95% confidence interval, 1.02-3.29). Patients operated for degenerative spinal disorders also had a significantly higher incidence of LFCN injury (odds ratio, 2.81; 95% confidence interval, 1.53-5.13). Recovery took 10.5 days on average (range, 2 days to 2 months). Thirty-two patients (53%) recovered completely within the first week and every patient recovered within 2 months. Postoperative meralgia paresthetica is a common but benign complication of posterior thoracolumbar spine surgery. Degenerative spinal disorders, overweight/obesity, and longer surgical time are factors related to a higher incidence of LFCN injury. The clinical outcome is always excellent, and complete recovery can be expected within 2 months.

    This study is a retrospective consecutive case series analysis of 198 patients who underwent spine surgery between 2009 and 2010. The aim of this paper was to assess the efficacy and safeness of bed rest and lumbar drainage in treating postoperative CSF fistula. Postoperative cerebrospinal fluid (CSF) fistula is a well-known complication in spine surgery which lead to a significant change in length of hospitalization and possible postoperative complications. Management of CSF leaks has changed little over the past 20 years with no golden standard advocated from literature. Postoperative CSF fistulas were described in 16 of 198 patients (8%) who underwent spine surgery between 2009 and 2010. The choice of the therapeutic strategy was based on the clinical condition of the patients, taking into account the possibility to maintain the prone position continuously and the risk of morbidity due to prolonged bed rest. Six patients were treated conservatively (position prone for three weeks), ten patients were treated by positioning an external CSF lumbar drainage for ten days. The mean follow-up period was ten months. All patients healed their wound properly and no adverse events were recorded. Patients treated conservatively were cured in a mean period of 30 days, while patients treated with CSF drainage were cured in a mean period of 10 days. Lumbar drainage seems to be effective and safe both in preventing CSF fistula in cases of large dural tears and debilitated/irradiated patients and in treating CSF leaks.

    Many techniques have been proposed for surgical training as a learning process for young surgeons or for the simulation of complex procedures. Stereolithograpfy, a rapid prototyping technique, has been presented recently as an option for these purposes. We describe the case of a 12 years old boy, diagnosed with Ewing's sarcoma in the cervical spine. After a surgical simulation accomplished in the prototype, built by stereolithography, the patient was submitted to a C4 corpectomy and to a C4 and C3 laminectomy with anterior and posterior fixation, a non intercurrence procedure. This technique is an innovative and complementary tool in diagnosis and therapy. As a result, it is easier for the surgeon to understand the complexity of the case and plan the approach before any surgical procedure.

  15. Effect of buprenorphine on total intravenous anesthetic requirements during spine surgery.

    Buprenorphine is a partial mu receptor agonist and kappa/delta antagonist commonly used for the treatment of opioid dependence or as an analgesic. It has a long plasma half-life and a high binding affinity for opioid receptors. This affinity is so high, that the effects are not easily antagonized by competitive antagonists, such as naloxone. The high affinity also prevents binding of other opioids, at commonly used clinical doses, to receptor sites - preventing their analgesic and likely minimum alveolar concentration (MAC) reducing benefits. This case report contrasts the anesthetic requirements of a patient undergoing emergency cervical spine surgery while taking buprenorphine with anesthetic requirements of the same patient undergoing a similar procedure after weaning of buprenorphine. Use of intraoperative neurophysiological monitoring prevented use of paralytics and inhalational anesthetics during both cases, therefore total intravenous anesthesia (TIVA) was maintained with propofol and remifentanil infusions. During the initial surgery, intraoperative patient movement could not be controlled with very high doses of propofol and remifentanil. The patient stopped moving in response to surgical stimulation only after the addition of a ketamine. Buprenorphine-naloxone was discontinued postoperatively. Five days later the patient underwent a similar cervical spine surgery. She had drastically reduced anesthetic requirements during this case, suggesting buprenorphine's profound effect on anesthetic dosing. This case report elegantly illustrates that discontinuation of buprenorphine is likely warranted for patients who present for major spine surgery, which necessitates the avoidance of volatile anesthetic and paralytic agents. The addition of ketamine may be necessary in patients maintained on buprenorphine in order to ensure a motionless surgical field.

    The United States has the highest rate of lumbar spine surgery in the world, with rates increasing over 200% since 1990. Medicare spends over $1 billion annually on lumbar spine surgery. Despite surgical advances, up to 40% of patients report chronic pain and disability following surgery. Our work has demonstrated that fear of movement is a risk factor for increased pain and disability and decreased physical function in patients following lumbar spine surgery for degenerative conditions. Cognitive-behavioral therapy and self-management treatments have the potential to address psychosocial risk factors and improve outcomes after spine surgery, but are unavailable or insufficiently adapted for postoperative care. Our research team developed a cognitive-behavioral based self-management approach to postoperative rehabilitation (Changing Behavior through Physical Therapy (CBPT)). Pilot testing of the CBPT program demonstrated greater improvement in pain, disability, physical and mental health, and physical performance compared to education. The current study compares which of two treatments provided by telephone - a CBPT Program or an Education Program about postoperative recovery - are more effective for improving patient-centered outcomes in adults following lumbar spine surgery for degenerative conditions. A multi-center, comparative effectiveness trial will be conducted. Two hundred and sixty patients undergoing lumbar spine surgery for degenerative conditions will be recruited from two medical centers and community surgical practices. Participants will be randomly assigned to CBPT or Education at 6 weeks following surgery. Treatments consist of six weekly telephone sessions with a trained physical therapist. The primary outcome will be disability and secondary outcomes include pain, general health, and physical activity. Outcomes will be assessed preoperatively and at 6 weeks, 6 months and 12 months after surgery by an assessor masked to group allocation

    Background Spine surgery using computer-assisted navigation (CAN) has been proven to result in low screw misplacement rates, low incidence of radiation exposure and excellent operative field viewing versus the conventional intraoperative image intensifier (CⅢ). However, as we know, few previous studies have described the learning curve of CAN in spine surgery.Methods We performed two consecutive case cohort studies on pedicel screw accuracy and operative time of two spine surgeons with different experience backgrounds, A and B, in one institution during the same period. Lumbar pedicel screw cortical perforation rate and operative time of the same kind of operation using CAN were analyzed and compared using CⅢ for the two surgeons at initial, 6 months and 12 months of CAN usage.Results CAN spine surgery had an overall lower cortical perforation rate and less mean operative time compared with CⅢ for both surgeon A and B cohorts when total cases of four years were included. It missed being statistically significant,with 3.3% versus 4.7% (P=0.191) and 125.7 versus 132.3 minutes (P=0.428) for surgeon A and 3.6% versus 6.4%(P=0.058), and 183.2 versus 213.2 minutes (P=0.070) for surgeon B. in an attempt to demonstrate the learning curve,the cases after 6 months of the CAN system in each surgeon's cohort were compared. The perforation rate decreased by 2.4% (P=0.039) and 4.3% (P=0.003) and the operative time was reduced by 31.8 minutes (P=0.002) and 14.4 minutes (P=0.026) for the CAN groups of surgeons A and B, respectively. When only the cases performed after 12 months using the CAN system were considered, the perforation rate decreased by 3.9% (P=0.006) and 5.6% (P <0.001) and the operative time was reduced by 20.9 minutes (P <0.001) and 40.3 minutes (P <0.001) for the CAN groups of surgeon A and B, respectively.Conclusions In the long run, CAN spine surgery decreased the lumbar screw cortical perforation rate and operative time. The learning curve showed a

    To study the effect of spine surgery (SpS) on gastric function and the efficacy of relevant treatments. Sixty patients in the spine surgery group, 20 patients in the extremity surgery (ES) group and 20 healthy subjects in the control group were observed. Electrogastrography (EGG) was used to observe gastroelectric activity before and after operation. Twenty patients among the SpS group were examined with barium meal under actinoscopy to observe the gastric peristaltic waves before and after operation. The SpS group was randomly subdivided into 3 groups, and treated by Xiangsha Yangwei pill (XSYW), moxibustion and motilium respectively. At the same time, the EGG of various groups was observed and the change of preoperative and postoperative EGG were compared. The gastroelectric rhythm of SpS group was remarkably abnormal, both frequency and amplitude of EGG were significantly different from the other two groups (P 0.05). SpS could change the gastroelectric rhythm to cause the gastric functional disorder and induce gastroparesis, EGG can get satisfactory results in the diagnosis of these illnesses. XSYW, moxibustion and motilium all have significant effects on the gastric function after SpS.

    Few studies have examined gender differences in patient-oriented health-related quality of life before and after spine surgery. This study examined the influence of gender on baseline status and 1-year postoperative outcomes in a large series of patients undergoing surgery for different degenerative spinal disorders. The study included 1518 patients [812 men and 706 women; mean (SD) age 61.4 ± 16.2 years], with three different pathologies (disc herniation, degenerative spondylolisthesis, or spinal stenosis), treated with specified surgical approaches. Preoperatively and 12 months postoperatively, patients completed the multidimensional Core Outcome Measures Index (COMI). Medical history, surgical details and perioperative complications were documented with the Eurospine "Spine Tango" Surgery 2006 form. Preoperatively and for all three pathologies, women had significantly (p 0.05). 71.3 % males and 72.9 % females achieved the minimal clinically important change score (MCIC; 2.2 point reduction) for the COMI. Controlling for potential cofounders (preoperative COMI, ASA, complications, pathology), gender showed no significant association with the failure to achieve MCIC. This results show that women do not differ significantly from men regarding their postoperative outcome, even though they present with a worse preoperative status. The management of a patient's condition should not differ depending on their gender, since both men and women are able to improve to a similar extent.

    Full Text Available Background Context. Percutaneous balloon kyphoplasty is an established minimally invasive technique to treat painful vertebral compression fractures, especially in the context of osteoporosis with a minor complication rate. Purpose. To describe the heparin anticoagulation treatment of paraplegia following balloon kyphoplasty. Study Design. We report the first case of an anterior spinal artery syndrome with a postoperative reversible paraplegia following a minimally invasive spine surgery (balloon kyphoplasty without cement leakage. Methods. A 75-year-old female patient underwent balloon kyphoplasty for a fresh fracture of the first vertebra. Results. Postoperatively, the patient developed an acute anterior spinal artery syndrome with motor paraplegia of the lower extremities as well as loss of pain and temperature sensation with retained proprioception and vibratory sensation. Complete recovery occurred six hours after bolus therapy with 15.000 IU low-molecular heparin. Conclusion. Spine surgeons should consider vascular complications in patients with incomplete spinal cord syndromes after balloon kyphoplasty, not only after more invasive spine surgery. High-dose low-molecular heparin might help to reperfuse the Adamkiewicz artery.

  2. C5 Nerve root palsies following cervical spine surgery: A review

    Directory of Open Access Journals (Sweden)

    Nancy E Epstein

    2015-01-01

    Full Text Available Background: Cervical C5 nerve root palsies may occur in between 0% and 30% of routine anterior or posterior cervical spine operations. They are largely attributed to traction injuries/increased cord migration following anterior/posterior decompressions. Of interest, almost all studies cite spontaneous resolution of these deficits without surgery with 3-24 postoperative months. Methods: Different studies cite various frequencies for C5 root palsies following anterior or posterior cervical spine surgery. In their combined anterior/posterior series involving C4-C5 level  decompressions, Libelski et al. cited up to a 12% incidence of C5 palsies. In Gu et al. series, C5 root palsies occurred in 3.1% of double-door laminoplasty, 4.5% of open-door laminoplasty, and 11.3% of laminectomy. Miller et al. observed an intermediate 6.9% frequency of C5 palsies followed by posterior cervical decompressions and fusions (PCDF. Results: Gu et al. also identified multiple risk factors for developing C5 palsies following posterior surgery; male gender, ossification of the posterior longitudinal ligament (OPLL, narrower foramina, laminectomy, and marked dorsal spinal cord drift. Miller et al. also identified an average $1918 increased cost for physical/occupational therapy for patients with C5 palsies. Conclusions: The incidence of C5 root deficits for anterior/posterior cervical surgery at C4-C5 was 12% in one series, and ranged up to 11.3% for laminectomies, while others cited 0-30%. Although identification of preoperative risk factors for C5 root deficits may help educate patients regarding these risks, there is no clear method for their avoidance at this time.

    Patient-controlled analgesia (PCA) is regularly used to manage pain following major surgery. The fentanyl hydrochloride iontophoretic transdermal system (ITS) was developed to overcome some of the limitations of intravenous (IV) PCA. The small, self-adhesive, needle-free disposable system is applied to the skin on the upper arm or chest and is controlled by patients clicking a button on the device. The authors identified patients who were underwent spinal surgery from 2 prior multicenter, randomized studies and analyzed their data. Of the 1296 patients in the original trials, 170 underwent spine surgery procedures: 90 were randomized to the fentanyl ITS (40 mcg/activation) and 80 to IV PCA morphine (1 mg/dose). More patients treated with the fentanyl ITS rated their method of pain control as "excellent" across all time points, but differences did not reach statistical significance. However, investigators' ratings of "excellent" satisfaction with study treatment were significantly higher for the fentanyl ITS. Discontinuation rates and overall adverse event rates were similar between groups. The only significant difference was that patients treated with the fentanyl ITS had a higher rate of application site reactions than infusion site reactions in the IV PCA morphine group; the reactions were typically mild-to-moderate erythema that resolved shortly after removal of the fentanyl ITS device and did not require further treatment. Ratings of satisfaction with pain control method were consistently higher for the fentanyl ITS than the IV PCA morphine. The 2 groups had a similar safety profile. These results suggest that the fentanyl ITS appears to be a safe, efficacious alternative to IV PCA in spine surgery patients.

    MIGUEL ÁNGEL ANDRADE-RAMOS

    Full Text Available ABSTRACT Objective: To describe our experience on a case series treated with minimal invasive techniques in spine surgery, with short-term follow-up and identify complications. Methods: A prospective analysis was performed on 116 patients operated on by the same team from September 2015 to June 2016. Evaluating the short-term follow-up we registered the surgical time, bleeding, complications, hospital stay, pre- and postoperatively neurological status, as well as scales of disability and quality of life. Demographic and surgical procedure data were analyzed with SPSS version 20 program. Results: A total of 116 patients with a mean age of 49.7 + 15.7 (21-85 years underwent surgery being 76 (65% with lumbar conditions and 37 (32% with cervical conditions. The most common procedures were tubular discectomies (31, tubular bilateral decompression (17, lumbar MI-TLIFs (7, and anterior cervical discectomy and fusion (35. The mean blood loss was 50.6 cc, the hospital stay was 1.7 day, pre- and postoperative pain VAS were 7.4 % and 2.3%, respectively, pre- and postoperative Oswestry (ODI were 64.6% and 13.1%, respectively, pre- and postoperative SF-36 of 37.8% and 90.3%. There were no major complications, except for a surgical wound infection in diabetic patient and three incidental durotomies, one of these being a contained fistula, treated conservatively. Conclusions: The current tendency towards minimally invasive surgery has been justified on multiple studies in neoplastic and degenerative diseases, with the preservation of the structures that support the spine biomechanics. The benefits should not replace the primary objectives of surgery and its usefulness depends on the skills of the surgeon, pathology and the adequate selection of the techniques. We found that the tubular access allows developing techniques such as discectomy, corpectomy and fusion without limiting exposure, avoiding manipulation of adjacent structures, reducing complications and

    Full Text Available We present a rare complication of endoscopic staple repair of a pharyngeal diverticulum related to prior anterior cervical spine surgery. A 70-year-old male developed a symptomatic pharyngeal diverticulum 2 years after an anterior cervical fusion that was repaired via endoscopic stapler-assisted diverticulectomy. He initially had improvement of his symptoms after the stapler-assisted approach. Three years later, the patient presented with dysphagia and was found to have erosion of the cervical hardware into the pharyngeal lumen at the site of the prior repair. We present the first reported case of late hardware erosion into a pharyngeal diverticulum after endoscopic stapler repair.

    Meta-analyses are powerful tools that can synthesize existing research, inform clinical practice, and support evidence-based care. These studies have become increasingly popular in the spine surgery literature, but the rigor with which they are being conducted has not yet been evaluated. Our primary objectives were to evaluate the methodological quality (credibility) of spine surgery meta-analyses and to propose strategies to improve future research. Our secondary objectives were to evaluate completeness of reporting and identify factors associated with higher credibility and completeness of reporting. This study is based on a systematic survey of meta-analyses. We evaluated credibility according to the Users' Guide to the Medical Literature and completeness of reporting according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. We systematically searched MEDLINE, EMBASE, and The Cochrane Library, and two reviewers independently assessed eligibility, credibility, and completeness of reporting. We used multivariable linear regression to evaluate potential associations. Interrater agreement was quantified using kappa and intraclass correlation (ICC) coefficients. We identified 132 eligible meta-analyses of spine surgery interventions. The mean credibility score was 3 of 7 (standard deviation [SD], 1.4; ICC, 0.86), with agreement for each item ranging from 0.54 (moderate) to 0.83 (almost perfect). Clinical questions were judged as sensible in 125 (95%), searches were exhaustive in 102 (77%), and risk of bias assessments were undertaken in 91 (69%). Seven (5%) meta-analyses addressed possible explanations for heterogeneity using a priori subgroup hypotheses and 24 (18%) presented results that were immediately clinically applicable. Investigators undertook duplicate assessments of eligibility, risk of bias, and data extraction in 46 (35%) and rated overall confidence in the evidence in 24 (18%).

    Aim of this prospective randomized trial was to analyze the effectiveness of MESNA in chemical dissection of peridural fibrosis in patients who underwent revision lumbar spine surgery. Between January 2003 and October 2006, 30 patients who underwent revision lumbar spine surgery were enrolled in the study. Patients were randomly assigned to one of two groups: a study group (A) and a control group (B). Once peridural fibrosis was exposed, MESNA (Uromixetan MESNA, 50 mg/ml) was intraoperatively applied on the fibrous tissue (Group A) to ease tissue dissection and enter the canal. In patients of Group B, saline solution was used. Surgical time, preoperative and 1 week postoperative hemoglobin (Hb), length of hospitalization (days), and incidence of perioperative complications were evaluated. The blinded surgeon assigned the surgeries to one of four categories as none, minimal, moderate, and severe basing on intraoperative difficulty in dissecting the fibrous tissue and intraoperative bleeding. Statistical analysis used chi-square analysis to evaluate the difference in surgery difficulty and the incidence of intraoperative complications between the two groups. The analysis of surgical time and hemoglobin levels was performed using a one-sample Wilcoxon test and Mann–Whitney U test. Patients in whom MESNA was used intraoperatively (Group A) presented better intraoperative and perioperative parameters with respect to the control group. Average surgical time and decrease in Hb postoperatively were more in the saline group (B) respect to MESNA (A) (P = 0.004 and P = 0.001, respectively), while no difference in average hospital stay was reported between the two groups. Surgeon-blinded intraoperative report on surgical difficulty showed a significant difference between the two groups (P < 0.05). Postoperatively, no complications directly attributable to the use of MESNA were experienced. The incidence of dural tears and intraoperative bleeding from epidural veins

    OBJECTIVE Prior studies have shown obesity to be associated with higher complication rates but equivalent clinical outcomes following lumbar spine surgery. These findings have been reproducible across lumbar spine surgery in general and for lumbar fusion specifically. Nevertheless, surgeons seem inclined to limit the extent of surgery, perhaps opting for decompression alone rather than decompression plus fusion, in obese patients. The purpose of this study was to ascertain any difference in clinical improvement or complication rates between obese and nonobese patients following decompression alone compared with decompression plus fusion for lumbar spinal stenosis (LSS). METHODS The Quality Outcomes Database (QOD), formerly known as the National Neurosurgery Quality and Outcomes Database (N(2)QOD), was queried for patients who had undergone decompression plus fusion (D+F group) versus decompression alone (D+0 group) for LSS and were stratified by a body mass index (BMI) ≥ 30 kg/m(2) (obese) or obese cohort, 844 patients had decompression alone and 337 had decompression plus fusion. There were no significant differences in the Oswestry Disability Index score or in leg pain improvement at 12 months when comparing decompression with fusion to decompression without fusion in either obese or nonobese cohorts. However, absolute improvement in back pain was less in the obese group when decompression alone had been performed. Blood loss and operative time were lowest in the nonobese D+0 cohort and were higher in obese patients with or without fusion. Obese patients had a longer hospital stay (4.1 days) than the nonobese patients (3.3 days) when fusion had been performed. In-hospital stay was similar in both obese and nonobese D+0 cohorts. No significant differences were seen in 30-day readmission rates among the 4 cohorts. CONCLUSIONS Consistent with the prior literature, equivalent clinical outcomes were found among obese and non-obese patients treated for LSS. In

    Full Text Available Autologous Blood Transfusion (ABT is the safest type of blood transfusion for the operator and the patient. The preoperative donation technique had already been reduced the homologous blood requirements successfully. Homologous Blood Transfusion (HBT brings more risks in complications such as transmission of diseases, anaphylactic reactions, haemolitic reactions etc. This was a parallel study, comparing one group receiving ABT and a second group receiving HBT where in both groups were performed spine surgery. The parameter used was the hemoglobin(Hb and hematocrit(Ht content preoperatively (after donation of ABT and after transfusion, total days in hospitalization after surgery. Another purpose of this study was also to achieve understandings in using ABT by considering the total patients who finally required additional HBT. There were 74 patients with diagnosis of spine fracture, tuberculous spondylitis, scoliosis, spinal stenosis and spondylolisthesis. In the ABT group the average age was 33,9 ± 14 years old and the HBT group was 29,1 ± 11,5 years old. Both groups consisted of 21 males and 16 females. Body weight of the ABT group was 55,3 ± 11,1 kg and the HBT group 52,8 ± 9,7 kg. Amount of donations preoperatively in ABT was 798,6 ± 170 cc. There were 12 patients (32,4% where the donated blood amount preoperatively did not match up the requests. There were eight patients (21,6% in the ABT group that required additional HBT of about 550 cc. Three patients (8,1% of the ABT group received transfusion that did not match the indications (blood loss < 15% of the total blood volume. The Hb and Ht content preoperatively (after donation of the ABT group significantly was less than the HBT group (p= 0,001. Hb content after transfusion in the ABT group was not significantly less than the HBT group (p = 0,30. Hospitalization days after surgery were significantly higher in the HBT group (p = 0,000. In conclusions : there was 21,6% of the ABT group

    The Spine End Results Registry (2003-2004) is a registry of prospectively collected data of all patients undergoing spinal surgery at the University of Washington Medical Center and Harborview Medical Center. Insurance data were prospectively collected and used in multivariate analysis to determine risk of perioperative complications. Given the negative financial impact of surgical site infections (SSIs) and the higher overall complication rates of patients with a Medicaid payer status, we hypothesized that a Medicaid payer status would have a significantly higher SSI rate. The medical literature demonstrates lesser outcomes and increased complication rates in patients who have public insurance than those who have private insurance. No one has shown that patients with a Medicaid payer status compared with Medicare and privately insured patients have a significantly increased SSI rate for spine surgery. The prospectively collected Spine End Results Registry provided data for analysis. SSI was defined as treatment requiring operative debridement. Demographic, social, medical, and the surgical severity index risk factors were assessed against the exposure of payer status for the surgical procedure. The population included Medicare (N = 354), Medicaid (N = 334), the Veterans' Administration (N = 39), private insurers (N = 603), and self-pay (N = 42). Those patients whose insurer was Medicaid had a 2.06 odds (95% confidence interval: 1.19-3.58, P = 0.01) of having a SSI compared with the privately insured. The study highlights the increased cost of spine surgical procedures for patients with a Medicaid payer status with the passage of the Patient Protection and Affordable Care Act of 2010. The Patient Protection and Affordable Care Act of 2010 provisions could cause a reduction in reimbursement to the hospital for taking care of patients with Medicaid insurance due to their higher complication rates and higher costs. This very issue could inadvertently lead to access

    The spine contains intervertebral discs and the interspinous and longitudinal ligaments. These structures are elastomeric or viscoelastic in their mechanical properties and serve to allow and control the movement of the bony elements of the spine. The use of metallic or hard polymeric devices to replace the intervertebral discs and the creation of fusion masses to replace discs and/or vertebral bodies changes the load transfer characteristics of the spine and the range of motion of segments of the spine. The purpose of the study was to survey the literature, regulatory information available on the Web, and industry-reported device development found on the Web to ascertain the usage and outcomes of the use of polyurethane polymers in the design and clinical use of devices for spine surgery. A systematic review of the available information from all sources concerning the subject materials' usage in spinal devices was conducted. A search of the peer-reviewed literature combining spinal surgery with polyurethane or specific types and trade names of medical polyurethanes was performed. Additionally, information available on the Food and Drug Administration Web site and for corporate Web sites was reviewed in an attempt to identify pertinent information. The review captured devices that are in testing or have entered clinical practice that use elastomeric polyurethane polymers as disc replacements, dynamic stabilization of spinal movement, or motion limitation to relieve nerve root compression and pain and as complete a listing as possible of such devices that have been designed or tested but appear to no longer be pursued. This review summarizes the available information about the uses to which polyurethanes have been tested or are being used in spinal surgery. The use of polyurethanes in medicine has expanded as modifications to the stability of the polymers in the physiological environment have been improved. The potential for the use of elastomeric materials to more

    Upper airway obstruction is one of the life-threatening events in cervical spine surgery. The risk is particularly great during the period immediately after operation. We present the case of a 56-year-old female with breast cancer and metastasis to the cervical spine. The surgical procedure involved C2-C3 laminectomy, posterior fixation (C0-C5), and C2 neurectomy. Tracheal extubation was carried out in the intensive care unit, and upper airway obstruction immediately followed. Emergency cricothyrotomy was performed under well-managed ventilation with a laryngeal mask after several failed intubation attempts. Over-flexion of the cervical spine fixation and severe prevertebral soft tissue swelling were the most probable causes of upper airway obstruction. With a well-adjusted angle for fixation of the cervical spine under fluoroscopic guidance before the procedure, such a surgical mishap could be avoided. Reintubation with a fiberscope might be considered first, and sustaining intubation for 2-3 days postoperatively could be safer in such high risk patients.

    Study Design Retrospective case series. Purpose To examine the efficacy of TachoSil for vessel injury in 6 patients who underwent anterior lumbar fusion surgery (ALF). Overview of Literature ALF for the lumbar spine has a high rate of success, although intraoperative concerns and iatrogenic complications are known, and injury of a major vessel is sometimes a complication. The efficacy of TachoSil, a fibrin-based hemostat, has been reported for several types of surgery; however, use of TachoSil for ALF surgery has not been described. Here, we report on the efficacy of TachoSil in 6 patients, who underwent ALF after vascular surgeons having difficulty in repairing vessels. Methods Two man and 4 women with average age of 50.8±10.9 (mean±standard deviation) were diagnosed with a vertebral tumor (2 patients), L4 degenerative spondylolisthesis (2 patients), and L5 spondylolytic spondylolisthesis (2 patients) and underwent ALF. The blood vessels injured included the common iliac vein in 2 patients and a branch of a segmental artery from the aorta in 4 patients. We consulted a vascular surgeon to suture or repair the vessels during surgery, and although the vascular surgeon attempted to address the injuries, suturing or repair was not possible in these cases. For this reason, we used TachoSil to repair the injury in the vessels walls or to stop the bleeding. Results Time to pressure hemostasis using TachoSil was 34±12 minutes, and total blood loss was 1,488±1,711 mL. Nevertheless, all vessel injuries were controlled by the use of TachoSil. Conclusions We recommend the use of TachoSil for vessel injuries that vascular surgeons cannot suture or repair during ALF surgery. PMID:27790323

    Study Design Retrospective case series. Objective To determine the effect of obesity on the resource utilization and cost in 3270 consecutive patients undergoing elective noninstrumented decompressive surgeries for degenerative spine disease at Mayo Clinic Rochester between 2005 and 2012. Methods Groups were assessed for baseline differences (age, gender, and American Society of Anesthesiologists [ASA] classification, procedure type, and number of operative levels). Outcome variables included the transfusion requirements during surgery, the total anesthesia and surgical times, intensive care unit (ICU) admissions, standardized costs, as well as the ICU and hospital length of stay (LOS). Regression analysis was used to evaluate for strength of association between obesity and outcome variables. Results Baseline differences between the groups (nonobese: n = 1,853; obese: n = 1,417) were found with respect to age, ASA class, gender, procedure type, and number of operative levels. After correcting for differences, we found significant associations between obesity and surgical (p degenerative spine disease.

    Intraoperative neurophysiological monitoring during spine surgery is usually acomplished avoiding muscle relaxants. A case of intraoperative sugammadex partial reversal of the neuromuscular blockade allowing adequate monitoring during spine surgery is presented. A 38 year-old man was scheduled for discectomy and vertebral arthrodesis throughout anterior and posterior approaches. Anesthesia consisted of total intravenous anesthesia plus rocuronium. Intraoperatively monitoring was needed, and the muscle relaxant reverted twice with low dose sugammadex in order to obtain adequate responses. The doses of sugammadex used were conservatively selected (0.1mg/kg boluses increases, total dose needed 0.4mg/kg). Both motor evoqued potentials, and electromyographic responses were deemed adequate by the neurophysiologist. If muscle relaxation was needed in the context described, this approach could be useful to prevent neurological sequelae. This is the first study using very low dose sugammadex to reverse rocuronium intraoperatively and to re-establish the neuromuscular blockade.

    In our department, first-generation cephem (CEZ) are generally administered for 2 days as antimicrobial prophylaxis (AMP) for spinal surgery. However, the incidence of surgical site infection (SSI) has recently increased, particularly cases involving coagulase-negative Staphylococci (CNS) as an etiologic agent. The objective was to elucidate the problems with the current AMP and the risk factors of SSI through a retrospective investigation of affected cases. The subjects were patients who underwent spine surgery at our department between August 2007 and June 2013. The subjects were divided into those who developed SSI (S group) and who did not develop SSI (non-SSI (N) group), patients who developed CNS infection in the S group was subdivided as C group, and the risk factors were investigated. The significance of each factor was analyzed using cross tabulation, and multivariate logistic regression analyses were performed with 22 of the investigation factors as explanatory variables. The incidence of SSI was 2.55%, and the etiologic agent was CNS in 17 patients. Upon comparison between the S and N groups, the presence of 3 or more underlying diseases and blood loss were extracted as significant risk factors. Upon comparison between the C and N groups, emergency surgery and intra- and postoperative steroid administration were extracted as significant risk factors, in addition to the presence of 3 or more underlying diseases and blood loss. The effect of the current AMP using first generation cephem is limited, and reconsideration of the protocol may be necessary.

    Full Text Available Background: Lateral cutaneous femoral nerve (LCFN injury or Meralgia paraesthetica (MP results in restriction of activity. Compression of the nerve by disc hernia, retroperitoneal tumors, and external pressure around the anterior superior iliac spine is common. However, it is not commonly observed after lumbar spinal surgery in prone position. Study design: In this prospective study of 110 patients who underwent elective lumbar spinal surgery, managed from January 2002 to June 2002, the incidence, possible risk factors, etiopathogenesis and management of MP were analyzed. Results: There were 66 males and 44 females. The age of the patients ranged from 15 to 81 years (mean 46.9 yrs.. Thirteen patients (12% suffered from MP. It is more common in thinner individuals due to pressure injury to the nerve at its exit point. Ninety-two per cent of the patients were asymptomatic at follow-up after 6 months. In 7 out of 13 patients, patchy sensory loss on clinical examination was seen at 6 months. Conclusion: MP after posterior lumbar spinal surgery is uncommon. Smaller bolsters may avoid some of the vulnerable pressure points, as the surface area available is relatively smaller. The posts of the Hall-Relton frame over the anterior superior iliac crest should be adequately padded. The condition is usually self-limiting. Surgical division or decompression of the LCFN is reserved for persistent or severe MP.

  19. Design and Fabrication of a Precision Template for Spine Surgery Using Selective Laser Melting (SLM

    2016-07-01

    Full Text Available In order to meet the clinical requirements of spine surgery, this paper proposes the fabrication of the customized template for spine surgery through computer-aided design. A 3D metal printing-selective laser melting (SLM technique was employed to directly fabricate the 316L stainless steel template, and the metal template with tiny locating holes was used as an auxiliary tool to insert spinal screws inside the patient’s body. To guarantee accurate fabrication of the template for cervical vertebra operation, the contact face was placed upwards to improve the joint quality between the template and the cervical vertebra. The joint surface of the printed template had a roughness of Ra = 13 ± 2 μm. After abrasive blasting, the surface roughness was Ra = 7 ± 0.5 μm. The surgical metal template was bound with the 3D-printed Acrylonitrile Butadiene Styrene (ABS plastic model. The micro-hardness values determined at the cross-sections of SLM-processed samples varied from HV0.3 250 to HV0.3 280, and the measured tensile strength was in the range of 450 MPa to 560 MPa, which showed that the template had requisite strength. Finally, the metal template was clinically used in the patient’s surgical operation, and the screws were inserted precisely as the result of using the auxiliary template. The geometrical parameters of the template hole (e.g., diameter and wall thickness were optimized, and measures were taken to optimize the key geometrical units (e.g., hole units in metal 3D printing. Compared to the traditional technology of screw insertion, the use of the surgical metal template enabled the screws to be inserted more easily and accurately during spinal surgery. However, the design of the high-quality template should fully take into account the clinical demands of surgeons, as well as the advice of the designing engineers and operating technicians.

    The past several years have demonstrated an increased recognition of operative videos as an important adjunct for resident education. Currently lacking, however, are effective methods to record video for the purposes of illustrating the techniques of minimally invasive (MIS) and complex spine surgery. We describe here our experiences developing and using a shoulder-mounted camera system for recording surgical video. Our requirements for an effective camera system included wireless portability to allow for movement around the operating room, camera mount location for comfort and loupes/headlight usage, battery life for long operative days, and sterile control of on/off recording. With this in mind, we created a shoulder-mounted camera system utilizing a GoPro™ HERO3+, its Smart Remote (GoPro, Inc., San Mateo, California), a high-capacity external battery pack, and a commercially available shoulder-mount harness. This shoulder-mounted system was more comfortable to wear for long periods of time in comparison to existing head-mounted and loupe-mounted systems. Without requiring any wired connections, the surgeon was free to move around the room as needed. Over the past several years, we have recorded numerous MIS and complex spine surgeries for the purposes of surgical video creation for resident education. Surgical videos serve as a platform to distribute important operative nuances in rich multimedia. Effective and practical camera system setups are needed to encourage the continued creation of videos to illustrate the surgical maneuvers in minimally invasive and complex spinal surgery. We describe here a novel portable shoulder-mounted camera system setup specifically designed to be worn and used for long periods of time in the operating room.

    Purpose: Localization of target anatomy and critical structures defined in preoperative MR images can be achieved by means of multi-modality deformable registration to intraoperative CT. We propose a symmetric diffeomorphic deformable registration algorithm incorporating a modality independent neighborhood descriptor (MIND) and a robust Huber metric for MR-to-CT registration. Method: The method, called MIND Demons, solves for the deformation field between two images by optimizing an energy functional that incorporates both the forward and inverse deformations, smoothness on the velocity fields and the diffeomorphisms, a modality-insensitive similarity function suitable to multi-modality images, and constraints on geodesics in Lagrangian coordinates. Direct optimization (without relying on an exponential map of stationary velocity fields used in conventional diffeomorphic Demons) is carried out using a Gauss-Newton method for fast convergence. Registration performance and sensitivity to registration parameters were analyzed in simulation, in phantom experiments, and clinical studies emulating application in image-guided spine surgery, and results were compared to conventional mutual information (MI) free-form deformation (FFD), local MI (LMI) FFD, and normalized MI (NMI) Demons. Result: The method yielded sub-voxel invertibility (0.006 mm) and nonsingular spatial Jacobians with capability to preserve local orientation and topology. It demonstrated improved registration accuracy in comparison to the reference methods, with mean target registration error (TRE) of 1.5 mm compared to 10.9, 2.3, and 4.6 mm for MI FFD, LMI FFD, and NMI Demons methods, respectively. Validation in clinical studies demonstrated realistic deformation with sub-voxel TRE in cases of cervical, thoracic, and lumbar spine. Conclusions: A modality-independent deformable registration method has been developed to estimate a viscoelastic diffeomorphic map between preoperative MR and intraoperative CT

    OBJECT The rate of 30-day readmissions is rapidly gaining significance as a quality metric and is increasingly used to evaluate performance. An analysis of the present 30-day readmission rate in the spine literature is needed to aid the development of policies to decrease the frequency of readmissions. The authors examine 2 questions: 1) What is the 30-day readmission rate as reported in the spine literature? 2) What study factors impact the rate of 30-day readmissions? METHODS This study was registered with Prospera (CRD42014015319), and 4 electronic databases (PubMed, Cochrane Library, Web of Science, and Google Scholar) were searched for articles. A systematic review and meta-analysis was performed to assess the current 30-day readmission rate in spine surgery. Thirteen studies met inclusion criteria. The readmission rate as well as data source, time from enrollment, sample size, demographics, procedure type and spine level, risk factors for readmission, and causes of readmission were extrapolated from each study. RESULTS The pooled 30-day readmission rate was 5.5% (95% CI 4.2%-7.4%). Studies from single institutions reported the highest 30-day readmission rate at 6.6% (95% CI 3.8%-11.1%), while multicenter studies reported the lowest at 4.7% (95% CI 2.3%-9.7%). Time from enrollment had no statistically significant effect on the 30-day readmission rate. Studies including all spinal levels had a higher 30-day readmission rate (6.1%, 95% CI 4.1%-8.9%) than exclusively lumbar studies (4.6%, 95% CI 2.5%-8.2%); however, the difference between the 2 rates was not statistically significant (p = 0.43). The most frequently reported risk factors associated with an increased odds of 30-day readmission on multivariate analysis were an American Society of Anesthesiology score of 4+, operative duration, and Medicare/Medicaid insurance. The most common cause of readmission was wound complication (39.3%). CONCLUSIONS The 30-day readmission rate following spinal surgery is

    2015-01-01

    Full Text Available This study evaluates the safety and effectiveness of computed tomography- (CT- assisted endoscopic surgery in the treatment of infectious spondylodiscitis of the thoracic and upper lumbar spine in immunocompromised patients. From October 2006 to March 2014, a total of 41 patients with infectious spondylodiscitis underwent percutaneous endoscopic surgery under local anesthesia, and 13 lesions from 13 patients on the thoracic or upper lumbar spine were selected for evaluation. A CT-guided catheter was placed before percutaneous endoscopic surgery as a guide to avoid injury to visceral organs, major vessels, and the spinal cord. All 13 patients had quick pain relief after endoscopic surgery without complications. The bacterial culture rate was 77%. Inflammatory parameters returned to normal after adequate antibiotic treatment. Postoperative radiographs showed no significant kyphotic deformity when compared with preoperative films. As of the last follow-up visit, no recurrent infections were noted. Traditional transthoracic or diaphragmatic surgery with or without posterior instrumentation is associated with high rates of morbidity and mortality, especially in elderly patients, patients with multiple comorbidities, or immunocompromised patients. Percutaneous endoscopic surgery assisted by a CT-guided catheter provides a safe and effective alternative treatment for infectious spondylodiscitis of the thoracic and upper lumbar spine.

    The effect of corrective spine surgery on standing stability in adult spinal deformity (ASD) has not been fully documented. To compare pre- and postoperative standing balance and posture in patients with ASD. This study is a prospective case series. Standing balance before and after corrective spine surgery was compared in 35 consecutive female patients with ASD (65.6±6.9 years, body mass index 22.3±2.7 kg/m(2), Cobb angle 50.2±19.2°, C7 plumb line 9.3±5.6 cm, and pelvic incidence-lumbar lordosis mismatch 40.8±23.3°). The Scoliosis Research Society Patient Questionnaire, the Oswestry Disability Index, and force-plate analysis were used to evaluate the patient outcomes. We reviewed patient charts and X-rays and compared standing balance before and after corrective spine surgery. All subjects were assessed by force-plate analysis using optical markers while standing naturally on a custom-built force platform. The spinal tilt, pelvic obliquity, pelvic tilt, and joint angle were calculated. The lower leg lean volume was obtained by whole-body dual X-ray absorptiometry to assess muscle strength. ASD patients showed significant differences between the left and right sides in ground reaction force (dGRFs), hip (dHip), and knee angle (dKnee) while standing (dGRF 15.1±8.7%, dHip 7.1±6.6°, dKnee 5.9±5.5°). The recorded center-of-gravity (CoG) area was not improved after surgery, whereas the dGRF, dHip, and dKnee all decreased. The spinal tilt, pelvic obliquity, and pelvic tilt were all significantly improved after surgery. We found significant correlations between the radiographic trunk shift and the postoperative coronal CoG distance and recorded CoG area, and between the sagittal CoG distance and the age and the lean volume of the lower extremities (trunk shift R=0.33, 0.45; age R=0.32; lean volume R=0.31). Corrective spinal surgery improved the spinal alignment and joint angles in patients with ASD but did not improve the standing stability. A correlation

    To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. Retrospective analysis of 583 surgically-treated patients. Early "major" complications were defined as those that may lead to permanent detrimental effects or require further significant intervention. A balanced risk score was built using multiple logistic regression. Ninety-two early major complications occurred in 76 patients (13%). Age > 60 years and surgery of three or more levels proved to be significant independent risk factors in the multivariate analysis. The balanced scoring system was defined as: 0 points (no risk factor), 2 points (1 factor) or 4 points (2 factors). The incidence of early major complications in each category was 7% (0 points), 15% (2 points) and 29% (4 points) respectively. This balanced scoring system, based on two risk factors, represents an important tool for both surgical indication and for patient counseling before surgery.

    Somatosensory profiling in affected and non-affected body regions can strengthen our insight regarding the underlying pain mechanisms, which can be valuable in treatment decision making and to improve outcomes, in patients with degenerative lumbar spine disorders pre-surgery. The aim was to describe somatosensory profiles in patients with degenerative lumbar spine disorders, to identify the proportion with altered somatosensory profile, and to analyze demographic characteristics, self-reported function, pain, and health pre- and 3 months post-surgery. In this prospective cohort study in a Spine Clinic, 105 patients scheduled for surgery for spinal stenosis, disc herniation, degenerative disc disease, or spondylolisthesis were consecutively recruited. Exclusion criteria were; indication for acute surgery or previous surgery at the same spinal level or severe grade of pathology. Quantitative sensory testing (QST) and self-reported function, pain, and health was measured pre- and 3 months post-surgery. The somatosensory profile included cold detection threshold, warmth detection threshold, cold pain threshold, heat pain threshold and pressure pain threshold in affected and non-affected body regions. On a group level, the patients' somatosensory profiles were within the 95% confidence interval (CI) from normative reference data means. On an individual level, an altered somatosensory profile was defined as having two or more body regions (including a non-affected region) with QST values outside of normal ranges for reference data. The 23 patients (22%) with altered somatosensory profiles, with mostly loss of function, were older (P = 0.031), more often female (P = 0.005), had higher back and leg pain (P = 0.016, 0.020), lower mental health component summary score (SF-36 MCS) (P = 0.004) and larger pain distribution (P = 0.047), compared to others in the cohort. Post-surgery there was a tendency to worse pain, function and health in the group with

    Full Text Available Abstract The recent article published in the Journal by Lindley and colleagues (Patient Saf. Surg. 2011, 5:33 reported the successful surgical treatment of a persistent thoracic pain following a T7-8 microdiscectomy, truly performed at the ‘level immediately above’. The wrong level in spine surgery is a multi-factorial matter and several strategies have been designed and adopted to try decreasing its occurrence. We think that three of these factors are crucial: global strategy, attention, precision in level identification; and the actors we identified are the surgeon, the assistant nurse and the (neuroradiologist respectively. Basing upon our experience, the role of the radiologist pre- and intraoperatively and the importance of the assistant nurse are briefly described.

    Vertebroplasty and kyphoplasty are commonly used minimally invasive methods to treat vertebral compression fractures. Novice surgeons gather surgical skills in different ways, mainly by "learning by doing" or training on models, specimens or simulators. Currently, a new training modality, an augmented reality simulator for minimally invasive spine surgeries, is going to be developed. An important step in investigating this simulator is the accurate establishment of artificial tissues. Especially vertebrae and muscles, reproducing a comparable haptical feedback during tool insertion, are necessary. Two artificial tissues were developed to imitate natural muscle tissue. The axial insertion force was used as validation parameter. It appropriates the mechanical properties of artificial and natural muscles. Validation was performed on insertion measurement data from fifteen artificial muscle tissues compared to human muscles measurement data. Based on the resulting forces during needle insertion into human muscles, a suitable material composition for manufacturing artificial muscles was found.

    Full Text Available Abstract OBJECTIVE To identify and describe the instruments used to assess patients' expectations toward spine surgery. METHOD An integrative review was carried out in the databases PubMed, CINAHL, LILACS and PsycINFO. RESULTS A total of 4,402 publications were identified, of which 25 met the selection criteria. Of the studies selected, only three used tools that had confirmed validity and reliability to be applied; in five studies, clinical scores were used, and were modified for the assessment of patients' expectations, and in 17 studies the researchers developed scales without an adequate description of the method used for their development and validation. CONCLUSION The assessment of patients' expectations has been methodologically conducted in different ways. Until the completion of this integrative review, only two valid and reliable instruments had been used in three of the selected studies.

    Conclusions: MIS surgery provides an opportunity for early pain relief in patients with discitis, osteomyelitis, spondylodiscitis, and/or epidural abscess by directly addressing the primary cause of pain. MIS surgery for discitis provides a higher diagnostic yield to direct antibiotic treatment. MIS surgery results in good long-term recovery.

    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.

    Achieving solid osseous fusion across the lumbosacral junction has historically been, and continues to be, a challenge in spine surgery. Robust pelvic fixation plays an integral role in achieving this goal. The goals of this review are to describe the history of and indications for spinopelvic fixation, examine conventional spinopelvic fixation techniques, and review the newer S2-alar-iliac technique and its outcomes in adult and pediatric patients with spinal deformity. Since the introduction of Harrington rods in the 1960s, spinal instrumentation has evolved substantially. Indications for spinopelvic fixation as a means to achieve lumbosacral arthrodesis include a long arthrodesis (five or more vertebral levels) or use of three-column osteotomies in the lower thoracic or lumbar spine, surgical treatment of high-grade spondylolisthesis, and correction of lumbar deformity and pelvic obliquity. A variety of techniques have been described over the years, including Galveston iliac rods, Jackson intrasacral rods, the Kostuik transiliac bar, iliac screws, and S2-alar-iliac screws. Modern iliac screws and S2-alar-iliac screws are associated with relatively low rates of pseudarthrosis. S2-alar-iliac screws have the advantages of less implant prominence and inline placement with proximal spinal anchors. Collectively, these techniques provide powerful methods for obtaining control of the pelvis in facilitating lumbosacral arthrodesis.

    Analysis of the National Inpatient Sample database from 2000 to 2008. To identify whether metabolic syndrome is an independent risk factor for increased major perioperative complications, cost, length of stay, and nonroutine discharge. Metabolic syndrome is a combination of medical disorders that has been shown to increase the health risk of the general population. No study has analyzed its impact in the perioperative spine surgery setting. We obtained the National Inpatient Sample from the Hospital Cost and Utilization Project for each year between 2000 and 2008. All patients undergoing primary posterior lumbar spine fusion were identified and separated into groups with and without metabolic syndrome. Patient demographics and health care system-related parameters were compared. The outcomes of major complications, nonroutine discharge, length of hospital stay, and hospitalization charges were assessed for both groups. Regression analysis was performed to identify whether the presence of metabolic syndrome was an independent risk factor for each outcome. An estimated 1,152,747 primary posterior lumbar spine fusions were performed between 2000 and 2008 in the United States. The prevalence of metabolic syndrome as well as the comorbidities of the patients increased significantly over time. Patients with metabolic syndrome had significantly longer length of stay, higher hospital charges, higher rates of nonroutine discharges, and increased rates of major life-threatening complications than patients without metabolic syndrome. Patients with metabolic syndrome undergoing primary posterior lumbar spinal fusion represent an increasing financial burden on the health care system. Clinicians should recognize that metabolic syndrome represents a risk factor for increased perioperative morbidity.

    A paucity of data exist studying outcomes of patients with syringomyelia undergoing spinal deformity correction. The literature does not stratify patients by syrinx size, which is likely a major contributor to outcomes. The study aimed to compare differences in outcomes between patients with large (≥4 mm) and small syrinxes (4 mm] and 17 with small syrinx [SS, <4 mm]). The outcome measures were radiographic, operative, and neurophysiological measures. We retrospectively reviewed 28 patients with syringomyelia who underwent spine deformity surgery with 2-year follow-up. Demographic, surgical, and radiographic data were collected and compared preoperatively and at 2 years. The LS group (11 patients) trended toward more left-sided thoracic curves (36% vs. 18%, p=.38) and was more likely to have had a Chiari decompression (45% vs. 12%, p=.08). The LS patients had larger preoperative major curves (LS=66° vs. SS=57°, p=.05), more thoracic kyphosis (LS=42°, SS=24°, p<.01), and greater rib prominences (LS=16°, SS=13°, p=.04). The LS patients had more levels fused (LS=12.2, SS=11.2, p=.05), higher estimated blood loss (EBL) (LS=1068 cc, SS=832 cc, p=.04), and a trend toward less percent correction of the major curve (LS=57%, SS=65%, p=.18). Four of 11 LS patients (36%) did not have somatosensory evoked potentials, and one of these also did not have motor evoked potentials. Neuromonitoring changes occurred in 3 of 11 (27%) LS patients and in none of the SS patients, with no postoperative deficits. Outcomes of patients with syringomyelia undergoing spine deformity surgery are dependent on the size of the syrinx. Those with large syringomyelia are fused longer with more EBL and less correction. Spine surgeons should be aware that these patients are more likely to have less reliable neuromonitoring, with a higher chance of experiencing a change. Copyright © 2017 Elsevier Inc.

    Image-guided spine surgery (IGSS) is associated with reduced co-morbidity and improved surgical outcome. However, precise localization of target anatomy and adjacent nerves and vessels relative to planning information (e.g., device trajectories) can be challenged by anatomical deformation. Rigid registration alone fails to account for deformation associated with changes in spine curvature, and conventional deformable registration fails to account for rigidity of the vertebrae, causing unrealistic distortions in the registered image that can confound high-precision surgery. We developed and evaluated a deformable registration method capable of preserving rigidity of bones while resolving the deformation of surrounding soft tissue. The method aligns preoperative CT to intraoperative cone-beam CT (CBCT) using free-form deformation (FFD) with constraints on rigid body motion imposed according to a simple intensity threshold of bone intensities. The constraints enforced three properties of a rigid transformation-namely, constraints on affinity (AC), orthogonality (OC), and properness (PC). The method also incorporated an injectivity constraint (IC) to preserve topology. Physical experiments involving phantoms, an ovine spine, and a human cadaver as well as digital simulations were performed to evaluate the sensitivity to registration parameters, preservation of rigid body morphology, and overall registration accuracy of constrained FFD in comparison to conventional unconstrained FFD (uFFD) and Demons registration. FFD with orthogonality and injectivity constraints (denoted FFD+OC+IC) demonstrated improved performance compared to uFFD and Demons. Affinity and properness constraints offered little or no additional improvement. The FFD+OC+IC method preserved rigid body morphology at near-ideal values of zero dilatation (D = 0.05, compared to 0.39 and 0.56 for uFFD and Demons, respectively) and shear (S = 0.08, compared to 0.36 and 0.44 for uFFD and Demons, respectively

    2014-01-01

    Thoracoscopic surgery or video-assisted thoracic surgery (VATS) of the thoracic and lumbar spine has greatly evolved since it appeared less than 20 years ago. Nowadays, it is indicated in a large number of processes and injuries. The aim of this article, in its 2 parts, is to review the current status of VATS in treatment of the thoracic and lumbar spine in its entire spectrum. After reviewing the current literature, we develop each of the large groups of indications where VATS is used, one by one. This first part contains a description of general thoracoscopic surgical technique including the necessary prerequisites, transdiaphragmatic approach, techniques and instrumentation used in spine reconstruction, as well as a review of treatment and specific techniques in the management of spinal fractures. 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 fractures and deformities, as well as the reconstruction of injured spinal segments and decompression of the spinal canal in any etiological processes if the lesion placement is favourable to antero-lateral approach. Good clinical results of thoracoscopic surgery are supported by the growing experience reflected in a large number of articles. The degree of complications in thoracoscopic surgery is comparable to open surgery, with benefits in morbidity of the approach and subsequent patient recovery.

    Demonstrating the value of spine care requires adequate outcomes assessment. Long-term outcomes are best measured as overall improvement in quality of life (QOL) after surgical intervention. Present registries often require parallel data entry, introducing inefficiencies and limiting compliance. The authors detail the methodology of constructing an integrated electronic health record (EHR) system to collect QOL metrics and demonstrate the effect of data collection on routine clinical workflow. A streamlined approach to collecting QOL data can capture patient data without requiring dual data entry and without increasing clinic visit times. Through extensive literature review, a combination of QOL assessments was selected, consisting of the Patient Health Questionnaire-2 and -9, Oswestry Disability Index, Neck Disability Index, and visual analog scale for pain. These metrics were used to provide assessment of QOL following spine surgery and were incorporated into standard clinic workflow by a multidisciplinary team of surgeons, advanced practice providers, and health care information technology specialists. A clinical dashboard tracking more than 25 patient variables was developed. Clinic flow was assessed and opportunities for improvement reviewed. Duration of clinic visits before and after initiation of QOL measure capture was recorded, with assessment of mean clinic visit times for the 12 months before and the 12 months after implementation. The integrated QOL capture was instituted for 3 spine surgeons in a tertiary care academic center. In the 12-month period prior to initiating collection of QOL data, 806 new patient visits were completed with an average visit time of 127.9 ± 51.5 minutes. In the 12 months after implementation, 1013 new patient visits were recorded, with 791 providing QOL measures with an average visit time of 117.0 ± 45.7 minutes. Initially the primary means of collecting patient outcome data was via paper form, with gradual transition to

    Full Text Available OBJECTIVE A comparative study to evaluate the efficacy of dexmedetomidine as a hypotensive agent in comparison to esmolol in Spine surgeries. METHODS 60 patients ASA I or II scheduled for routine spine surgeries were equally randomly assigned to receive either dexmedetomidine or esmolol. In DEX group, patients received loading dose of 1 μg/kg dexmedetomidine diluted in 10 mL 0.9% saline infused over 10 min. before induction of anaesthesia, followed by continuous infusion of 0.5 μg/kg/h. In E group, patients received esmolol as a loading dose 1 mg/kg as 10 mL total vol. in saline infused over 1 min. followed by continuous infusion of 0.5 mg/kg/h. In both groups, aim was to maintain MAP within 55-65 mmHg. All patients were premedicated with IV glycopyrrolate 5 μg/Kg, IV midazolam 0.05 mg/kg and fentanyl 2 μg/kg. Patients received standard anaesthetic technique with propofol 2 mg/kg. Anaesthesia was maintained with O2, N2O, sevoflurane at 2 MAC and atracurium 0.1 mg/kg. Surgical field was assessed using Average Category Scale and average blood loss was calculated. Hemodynamic variables (MAP and HR; intraoperative fentanyl consumption; Emergence time and total recovery from anaesthesia (Aldrete score ≥9 were recorded. Sedation score was determined at 15, 30, 60 min. after tracheal extubation and time to first analgesic request was recorded. RESULTS Both DEX group and E group reached the desired MAP (55-65 mmHg with no intergroup differences in MAP or HR. The average category scale for quality of the surgical field in the range of MAP (55-65 mmHg were <=2 with no significant differences between group scores during hypotensive period. The induction propofol dose was significantly lower in DEX group than E group (1.63±0.19 mg/kg versus (2.00±0.05 mg/kg respectively (P<0.000.

    Full Text Available Incidental durotomy is a common complication of lumbar spine operations for degenerative disorders. Its incidence varies depending on several risk factors and regarding the intra and postoperative management, there is no consensus. Our objective was to report our experience with incidental durotomy in patients who were operated on for lumbar disc herniation, lumbar spinal stenosis and revision surgeries. Between 2009 and 2012, 1259 patients were operated on for degenerative lumbar disorders. For primary operations, the surgical approach was mino-open, interlamar, uni- or bilateral, as for recurrences, the removal of the compressive element was intended: the epidural scar and the disc fragment. 863 patients (67,7% were operated on for lumbar disc herniation, 344 patients (27,3% were operated on for lumbar spinal stenosis and 52 patients (5% were operated for recurrences. The operations were performed by neurosurgeons with the same professional degree but with different operative volume. Unintentional durotomy occurred in 20 (2,3% of the patients with herniated disc, in 14 (4,07% of the patients with lumbar spinal stenosis and in 12 (23% of the patients who were operated on for recurrences. The most frequent risk factors were: obesity, revised surgery and the physician’s low operative volume. Intraoperative dural fissures were repaired through suture (8 cases, by applying muscle, fat graft or by applying curaspon, tachosil. There existed 4 CSF fistulas which were repaired at reoperation. Incidental dural fissures during operations for degenerative lumbar disorders must be recognized and immediately repaired to prevent complications such as CSF fistula, osteodiscitis and increased medical costs. Preventing, identifying and treating unintentional durotomies can be best achieved by respecting a neat surgical technique and a standardized treatment protocol.

  6. Unusual spine anatomy contributing to wrong level spine surgery: a case report and recommendations for decreasing the risk of preventable 'never events'

    Directory of Open Access Journals (Sweden)

    Lindley Emily M

    2011-12-01

    Full Text Available Abstract Background Wrong site surgery is one of five surgical "Never Events," which include performing surgery on the incorrect side or incorrect site, performing the wrong procedure, performing surgery on the wrong patient, unintended retention of a foreign object in a patient, and intraoperative/immediate postoperative death in an ASA Class I patient. In the spine, wrong site surgery occurs when a procedure is performed on an unintended vertebral level. Despite the efforts of national safety protocols, literature suggests that the risk for wrong level spine surgery remains problematic. Case Presentation A 34-year-old male was referred to us to evaluate his persistent thoracic pain following right-sided microdiscectomy at T7-8 at an outside institution. Postoperative imaging showed the continued presence of a herniated disc at T7-8 and evidence of a microdiscectomy at the level immediately above. The possibility that wrong level surgery had occurred was discussed with the patient and revision surgery was planned. During surgery, the site of the previous laminectomy was clearly visualized; however, we also experienced confusion when verifying the level of the previous surgery. We ultimately used the previous laminectomy site as a landmark for identifying and treating the correct pathologic level. Postoperative consultation with Musculoskeletal Radiology revealed the patient had two abnormalities in his spinal anatomy that made intraoperative counting of levels inaccurate, including a pair of cervical ribs at C7 and the absence of a pair of thoracic ribs. Conclusion This case highlights the importance of strict adherence to a preoperative method of vertebral labeling that focuses on the landmarks used to label a pathologic disc space, rather than simply relying on the reference to a particular level. That is, by designating the pathological level as the disc space associated with the fourth rib up from the last rib-bearing vertebrae, rather than

    Full Text Available Low back pain (LBP is a common medical problem with high morbidity and healthcare costs. The optimal management strategy, including the role of surgical intervention, remains controversial. The Spine Patient Outcomes Research Trials were randomized controlled studies conducted to assess the effectiveness of surgery for three of the most common conditions implicated in LBP: Intervertebral disc herniation, degenerative spondylolisthesis, and spinal stenosis. Despite challenges in data interpretation related to patient cross over, these studies support the efficacy of surgery as treatment for these three common conditions.

    Registration is a critical and important process in maintaining the accuracy of CT-based image-guided surgery. The aim of this study was to evaluate the effects of the area of intraoperative data sampling and number of sampling points on the accuracy of surface-based registration in a CT-based spinal-navigation system, using an optical three-dimensional localizer. A cadaveric dry-bone phantom of the lumbar spine was used. To evaluate registration accuracy, three alumina ceramic balls were attached to the anterior and lateral aspects of the vertebral body. CT images of the phantom were obtained (1-mm slice thickness, at1-mm intervals) using a helical CT scanner. Twenty surface points were digitized from five zones defined on the basis of anatomical classification on the posterior aspects of the target vertebra. A total of 20 sets of sampling data were obtained. Evaluation of registration accuracy accounted for positional and rotational errors. Of the five zones, the area that was the largest and easiest to expose surgically and to digitize surface points was the lamina. The lamina was defined as standard zone. On this zone, the effect of the number of sampling points on the positional and rotational accuracy of registration was evaluated. And the effects of the additional area selected for intraoperative data sampling on the registration accuracy were evaluated. Using 20 surface points on the posterior side of the lamina, positional error was 0.96 mm +/- 0.24 mm root-mean-square (RMS) and rotational error was 0.91 degrees +/- 0.38 degrees RMS. The use of 20 surface points on the lamina usually allows surgeons to carry out sufficiently accurate registration to conduct computer-aided spine surgery. In the case of severe spondylosis, however, it might be difficult to digitize the surface points from the lamina, due to a hypertrophic facet joint or the deformity of the lamina and noisy sampling data. In such cases, registration accuracy can be improved by combining use

    Multifidus muscle injury and atrophy are common after posterior lumbar spine surgery and are associated with low back pain and functional disability. In theory, muscle-splitting and retraction with a self-retaining retractor are considered to be the major surgical factors. The effects and mechanisms of retraction have been well studied, but the exact effect and possible mechanism of injury and atrophy after muscle-splitting still lack experimental evidence. New Zealand White rabbits were divided into two groups. In group S, through a skin and lumbodorsal fascial incision, the bilateral multifidus muscles were dissected from the osseous structures in the standard fashion, while in group C, only a skin and lumbodorsal fascial incision was made. In each group, the multifidus muscle was evaluated by magnetic resonance imaging (MRI) and by histological analysis at three and forty-eight hours and at one, three, six, twelve, and twenty-four weeks after surgery. In group C, there was no injury or atrophy of the multifidus muscle after surgery. In group S, the mean T2-weighted signal intensity ratios of gross multifidus to psoas on fat-suppressed T2-weighted cross-sectional MRI scans peaked on week 3 and returned to baseline on week 24. Necrosis and inflammation of the multifidus muscle were evident and became more severe at one week. Fibrotic change was mainly seen at three and six weeks after surgery, and fatty degeneration mainly occurred at twelve and twenty-four weeks. Decreased acetylcholine activity and granular degeneration of the neuromuscular junction were observed at all follow-up times, and the numbers of degenerating neuromuscular junctions increased significantly with time after surgery. The splitting approach is an important cause of multifidus muscle injury and atrophy in posterior lumbar spine surgery. Denervation and disuse may be important factors in multifidus muscle atrophy in the splitting approach. This study provides a basis for the prevention of

    In the last decade, costs of U.S. healthcare expenditures have been soaring, with billions of dollars spent on hospital readmissions. Identifying causes and risk factors can reduce soaring readmission rates and help lower healthcare costs. The aim of this is to determine if post-operative delirium in the elderly is an independent risk factor for 30-day hospital readmission after spine surgery. The medical records of 453 consecutive elderly (≥65years old) patients undergoing spine surgery at Duke University Medical Center from 2008 to 2010 were reviewed. We identified 17 (3.75%) patients who experienced post-operative delirium according to DSM-V criteria. Patient demographics, comorbidities, and post-operative complication rates were collected for each patient. Elderly patients experiencing post-operative delirium had an increased length of hospital stay (10.47days vs. 5.70days, p=0.009). Complication rates were similar between the cohorts with the post-operative delirium patients having increased UTI and superficial surgical site infections. In total, 12.14% of patients were re-admitted within 30-days of discharge, with post-operative delirium patients experiencing approximately a 4-fold increase in 30-day readmission rates (Delirium: 41.18% vs. No Delirium: 11.01%, p=0.002). In a multivariate logistic regression analysis, post-operative delirium is an independent predictor of 30-day readmission after spine surgery in the elderly (p=0.03). Elderly patients experiencing post-operative delirium after spine surgery is an independent risk factor for unplanned readmission within 30-days of discharge. Preventable measures and early awareness of post-operative delirium in the elderly may help reduce readmission rates.

    2008-10-01

    Full Text Available Abstract During the recent years improved operation techniques and administrative procedures have been developed for early rehabilitation. At the same time preoperative lifestyle intervention (prehabilitation has revealed a large potential for additional risk reduction. The aim was to assess the quality of life and to estimate the cost-effectiveness of standard care versus an integrated programme including prehabilitation and early rehabilitation. Methods The analyses were based on the results from 60 patients undergoing lumbar fusion for degenerative lumbar disease; 28 patients were randomised to the integrated programme and 32 to the standard care programme. Data on cost and health related quality of life was collected preoperatively, during hospitalisation and postoperatively. The cost was estimated from multiplication of the resource consumption and price per unit. Results Overall there was no difference in health related quality of life scores. The patients from the integrated programme obtained their postoperative milestones sooner, returned to work and soaked less primary care after discharge. The integrated programme was 1,625€ (direct costs 494€ + indirect costs 1,131€ less costly per patient compared to the standard care programme. Conclusion The integrated programme of prehabilitation and early rehabilitation in spine surgery is more cost-effective compared to standard care programme alone.

    Surgical simulators provide a safe environment where novice surgeons can acquire their surgical skills. Although the number of patients with diseases of the musculoskeletal system is growing, the development of orthopedic simulators is still in it's infancy. The aim of this work was to identify simulation-based assessment parameters for a novel simulator in minimally invasive spine surgery. Apart from parameters targeting the duration and the surgeon's economy of motion during percutaneous bone access, parameters characterizing the movement smoothness were also examined with respect to their suitability. The results indicated, that the overall duration, the number of instrument movements, the number of velocity peaks and the Movement Arrest Period Ratio are the most promising predictors of expertise. Targeting performance improvement, the overall duration (p = 0.001), the number of instrument movements (p = 0.003) and the traveled instrument path length (p = 0.009) detected significant differences between subsequent trials. Using these parameters, a study can be designed targeting the validity and reliability of the simulation-based assessment.

    Delgado-López, Pedro David; Castilla-Díez, José Manuel

    2017-07-24

    Obesity (BMI>30Kg/m(2)) is a pandemic with severe medical and financial implications. There is growing evidence that relates certain metabolic processes within the adipose tissue, preferentially abdominal fat, with a low-intensity chronic inflammatory state mediated by adipokines and other substances that favor disk disease and chronic low back pain. Obesity greatly conditions both the preoperative evaluation and the spinal surgical technique itself. Some meta-analyses have confirmed an increase of complications following lumbar spine surgery (mainly infections and venous thrombosis) in obese subjects. However, functional outcomes after lumbar spine surgery are favorable although inferior to the non-obese population, acknowledging that obese patients present with worse baseline function levels and the prognosis of conservatively treated obese cohorts is much worse. The impact of preoperative weight loss in spine surgery has not been prospectively studied in these patients. Copyright © 2017 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    Case report. To report the beneficial effects of kyphoplasty, cement augmentation and extension of posterior instrumentation in a patient with recurrent adjacent segment osteoporotic vertebral body fracture. A 72-year-old lady underwent multiple revision spine surgeries for recurrent adjacent segment osteoporotic vertebral body fracture. The patient underwent four surgeries in 6 years: (1) in 2005, posterior lumbar interbody fusion with stabilization (L4-S1) was done; (2) in August 2010, implants from L4-S1 were removed and revised, transforaminal lumbar interbody fusion was done at L2/L3 and L3/L4 along with pedicle screw stabilization from T12-S1; (3) in September 2011, revision surgery was attempted, wherein a kyphoplasty was done at T12 and the stabilization was extended to T4; (4) again in October 2011, a revision surgery was attempted, wherein a kyphoplasty was done at T5 along with stabilization using pedicular screws in the T2 and T3 vertebrae and lateral mass screws in the C6 vertebra. To current date, the patient is stable with good sagittal and coronal balance and walking pain free without support. The current case demonstrates the need for posterior spinal reconstruction in osteoporotic vertebral collapse. Cement augmentation and extension of posterior instrumentation are both viable techniques that could be used to improve stabilization in the elderly spine.

    DepoDur, an extended-release epidural morphine, has been used effectively for postoperative pain control following many orthopaedic and general surgery procedures and has provided prolonged analgesia when compared with Duramorph. The goal of this article was to compare the safety and analgesic efficacy of DepoDur versus Duramorph after lumbar spine surgery. A prospective, randomized, double-blind clinical study was completed at a single extended-stay ambulatory surgery center. All patients over 18 undergoing posterior lumbar spine fusions were considered for the study. Sixty patients were randomly assigned to a control or treatment group. The control group received DepoDur before surgery, while the treatment group received Duramorph. Although results show no significant differences between the two groups in postoperative visual analog pain scale scores, use of pain medication, and adverse events, subjects receiving DepoDur were less likely to receive Naloxone and oxygen supplementation, experience nausea or fever, and were more likely to experience hypotension. DepoDur proved to be safe and effective, offering similar prolonged analgesic activity when compared with Duramorph.

    The hyoid bone is used as a landmark in anterior upper cervical spine operations and is supposed to represent the level of C3 body. However, this correspondence between hyoid bone position and cervical level is not static and changes during surgery (extension after anesthesia). To find the cervical level corresponding to the position of hyoid bone before and after anesthesia and to evaluate the adequacy of its usage as a surgical landmark. A retrospective study. One hundred twenty-eight patients with degenerative cervical diseases who had undergone anterior cervical discectomy and fusion. Radiologic measure. For each patient, preanesthesia neutral, preanesthesia extension, and postanesthesia induction extension C-spine lateral image were obtained. The level of cervical vertebra that midline of hyoid bone indicated was measured by radiological method. A cervical vertebra was divided into three segments, consisting of upper half, lower half, and disc space, and each of these segments was considered as one level. The differences between pre- and postanesthesia induction hyoid positions were classified as minimal change (one level or less) and significant change (two levels or greater). Relationship between positional change of hyoid bone to gender, obesity, and age were respectively investigated. There were 20 cases of one-level distal displacement of the hyoid bone, 40 cases of two-level distal displacement, 34 cases of three-level distal displacement, 16 cases of 4-level distal displacement, and two cases of five-level distal displacement. In eight cases, there was no level change, and in the remaining 8 cases, the hyoid bone had been displaced proximally. There were 34 cases of minimal change. The remaining 94 cases (73.4%) had significant changes. No respective relationship was found between sex, obesity, age and pre-and postanesthesia induction positional change of hyoid bone. Among the 128 cases studied, 73.4% hyoid bone positions had changed by more than one

    Full Text Available Background : Often conventional Inhalational agents are used for maintenance of anaesthesia in spine surgery. This study was undertaken to compare propofol with isoflurane anaesthesia with regard to haemodynamic stability, early emergence, postoperative nausea and vomiting (PONV and early assessment of neurological functions. Patients & Methods: Eighty ASA grade I &II adult patients were randomly allocated into two groups. Patients in study group received inj propofol for induction as well as for maintenance along with N 2O+O2 and the control group patients received inj thiopentone for induction and N 2 O+O 2 +isoflurane for maintenance. BIS monitoring was used for titrating the anaesthetic dose adjustments in all patients. All patients received fentanyl boluses for intraoperative analgesia and atracurium as muscle relaxant. Statistical data containing haemodynamic parameters, PONV, emergence time, dose of drug consumed & quality of surgical field were recorded and compared using student t′ test and Chi square test. Results: The haemodynamic stability was coparable in both the groups. The quality of surgical field were better in study group. Though there was no significant difference in the recovery profile (8.3% Vs 9.02% between both the groups, the postoperative nausea and vomiting was less in propofol group than isoflurane group (25%Vs60%. The anaesthesia cost was nearly double for propofol than isoflurane anaesthesia. Conclusion: Haemodynamic stability was comparable in both the groups. There was no significant difference in the recovery time between intravenous and inhalational group. Patients in propofol group were clear headed at awakening and were better oriented to place than inhalational group.

    The treatment of pain continues to gain in saliency as a component of defining best practice in medical care. Music therapy is an integrative treatment modality that impacts patient outcomes in the treatment of spinal pain. At Mount Sinai Beth Israel, we conducted a mixed-methods study addressing the effects of music therapy interventions on the recovery of patients after spine surgery. The study combined standard medical approaches and integrative music therapy. Sixty patients (35 female, 25 male) ranging in age from 40 to 55 years underwent anterior, posterior, or anterior-posterior spinal fusion and were randomly assigned to either music therapy plus standard care (medical and nursing care with scheduled pharmacologic pain intervention) or standard care only. Measurements for both groups were completed before and after the intervention. Music therapy involved the use of patient-preferred live music that supported tension release/relaxation through incentive-based clinical improvisation, singing, and/or rhythmic drumming or through active visualization supported by live music that encompasses tension resolution. The control and music groups showed significant differences in degree and direction of change in the visual analog scale (VAS) pain ratings from before to after intervention (P = .01). VAS pain levels increased slightly in the control group (to 5.87 from 5.20) but decreased by more than 1 point in the music group (to 5.09 from 6.20). The control and music therapy groups did not differ in the rate of change in scores on Hospital Anxiety and Depression Scale (HADS) Anxiety (P = .62), HADS Depression (P = .85), or Tampa Scale for Kinesiophobia (P = .93). Both groups had slight increases in HADS Anxiety, comparable decreases in HADS Depression, and minimal changes in fear-related movement (Tampa scale).

    Systematic review. To identify risk factors and preventive methods for wound complications and instrumentation failure after metastatic spine surgery. We focused on two postoperative complications of metastatic spine tumor surgery: wound complications and instrumentation failure and preventive measures. We performed a systematic review of the literature from 1980 to 2015. The articles were analyzed for the presence of documented infection and/or wound complications and instrumentation failure. Forty articles met our inclusion criteria for wound complications and prevention. There is very low level of evidence that preoperative radiation, preoperative neurological deficit, revision procedures, and posterior approaches can contribute to wound complications (infections, wound dehiscence). There is very low level of evidence that plastic surgery soft tissue reconstruction, intrawound vancomycin powder, and percutaneous pedicle screws may prevent postoperative wound complications. Fourteen articles met our inclusion criteria for instrumentation failure. There is very low level of evidence that constructs greater than six levels, positive sagittal balance, preoperative radiation, and history of chest wall resection can contribute to implant failures. • For patients undergoing revision metastatic spine tumor surgery, plastic surgery should perform the soft tissue reconstruction (strong recommendation/very low quality of evidence).• For patients undergoing metastatic spine tumor surgery, plastic surgery may perform immediate soft tissue reconstruction (weak recommendation/very low quality of evidence).• For patients undergoing metastatic spine tumor surgery, intrawound vancomycin can be applied to decrease the risk of postoperative wound infections (weak recommendation/very low quality of evidence).• For patients undergoing metastatic spine tumor surgery, percutaneous pedicle screws can be placed to decrease the risk of postoperative wound complications (weak

    OBJECTIVE Patients undergoing spinal surgery are at risk for developing venous thromboembolism (VTE). The authors sought to identify risk factors for VTE in these patients. METHODS The American College of Surgeons National Surgical Quality Improvement Project database for the years 2006-2010 was reviewed for patients who had undergone spinal surgery according to their primary Current Procedural Terminology code(s). Clinical factors were analyzed to identify associations with VTE. RESULTS Patients who underwent spinal surgery (n = 22,434) were identified. The rate of VTE in the cohort was 1.1% (pulmonary embolism 0.4%; deep vein thrombosis 0.8%). Multivariate binary logistic regression analysis revealed 13 factors associated with VTE. Preoperative factors included dependent functional status, paraplegia, quadriplegia, disseminated cancer, inpatient status, hypertension, history of transient ischemic attack, sepsis, and African American race. Operative factors included surgery duration > 4 hours, emergency presentation, and American Society of Anesthesiologists Class III-V, whereas postoperative sepsis was the only significant postoperative factor. A risk score was developed based on the number of factors present in each patient. Patients with a score of ≥ 7 had a 100-fold increased risk of developing VTE over patients with a score of 0. The receiver-operating-characteristic curve of the risk score generated an area under the curve of 0.756 (95% CI 0.726-0.787). CONCLUSIONS A risk score based on race, preoperative comorbidities, and operative characteristics of patients undergoing spinal surgery predicts the postoperative VTE rate. Many of these risks can be identified before surgery. Future protocols should focus on VTE prevention in patients who are predisposed to it.

The aim of this meta-analysis is to compare the efficacy of epidural analgesia (EA and intravenous patient-controlled analgesia (IV-PCA following major spine surgery. We searched electronic databases, including the PubMed, EMBASE, Ovid and Cochrane databases, for randomized controlled trials (RCTs published before June 2016. The quality of the included trials was assessed using the Cochrane risk-of-bias tool. Random effects models were used to estimate the standardized mean differences (SMDs and relative risks (RRs, with the corresponding 95% confidence intervals (CI. Subgroup analyses stratified by the type of epidural-infused medication and epidural delivery were also performed. A total of 17 trials matched the inclusion criteria and were chosen for the following meta-analysis. Overall, EA provided significantly superior analgesia, higher patient satisfaction and decreased overall opioid consumption compared with IV-PCA following major spine surgery. Additionally, no differences were found in the side effects associated with these two methods of analgesia. Egger’s and Begg’s tests showed no significant publication bias. We suggest that EA is superior to IV-PCA for pain management after major spine surgery. More large-scale, high-quality trials are needed to verify these findings.

    Purpose. To extend the functionality of radiographic / fluoroscopic imaging systems already within standard spine surgery workflow to: 1) provide guidance of surgical device analogous to an external tracking system; and 2) provide intraoperative quality assurance (QA) of the surgical product. Methods. Using fast, robust 3D-2D registration in combination with 3D models of known components (surgical devices), the 3D pose determination was solved to relate known components to 2D projection images and 3D preoperative CT in near-real-time. Exact and parametric models of the components were used as input to the algorithm to evaluate the effects of model fidelity. The proposed algorithm employs the covariance matrix adaptation evolution strategy (CMA-ES) to maximize gradient correlation (GC) between measured projections and simulated forward projections of components. Geometric accuracy was evaluated in a spine phantom in terms of target registration error at the tool tip (TREx), and angular deviation (TREΦ) from planned trajectory. Results. Transpedicle surgical devices (probe tool and spine screws) were successfully guided with TREx30° (easily accommodated on a mobile C-arm). QA of the surgical product based on 3D-2D registration demonstrated the detection of pedicle screw breach with TRExConclusions. 3D-2D registration combined with 3D models of known surgical components provides a novel method for near-real-time guidance and quality assurance using a mobile C-arm without external trackers or fiducial markers. Ongoing work includes determination of optimal views based on component shape and trajectory, improved robustness to anatomical deformation, and expanded preclinical testing in spine and intracranial surgeries.

    Parthiban Chandra JKB

    2008-05-01

    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.

    Objective. The purpose of this study was to evaluate a new questionnaire to assess outcomes related to the midline anterior lumbar approach and to identify risk factors for negative patient responses. Methods. A retrospective review of 58 patients who underwent anterior lumbar surgery at a single institution for either degenerative disc disease or spondylolisthesis in 2009 was performed. The outcome measures included our newly developed Anterior Lumbar Surgery Questionnaire (ALSQ), ODI, and EQ-5D. Results. There were 58 patients available for followup, 27 women and 31 men. The average age at surgery was 50.8 years, with an average followup of 2.92 years. The average change in ODI was 34.94 (22.7) and EQ-5D was 0.28 (0.29). The rate of complications with the anterior approach was 10.3% and there was one male patient (3.2%) with retrograde ejaculation. Determination of the effectiveness of the new ALSQ revealed that it significantly correlated to the EQ-5D and ODI (P < 0.05). Smoking was associated with a negative response on thirteen questions. BMP use was not associated with a negative response on any sexual function questions. Conclusions. Our new Anterior Lumbar Surgery Questionnaire determines patient perceived complications related to the midline anterior lumbar surgical approach. PMID:25610657

    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 Background: The selection, neurodiagnostic evaluation, and surgical management of patients with cervical ossification of the posterior longitudinal ligament (OPLL remain controversial. Whether for prophylaxis or treatment, the decision to perform anterior vs. posterior vs. circumferential cervical OPLL surgery is complex. MR and CT Documentation of OPLL: Together, MR and CT cervical studies best document the full extent of OPLL. While MR provides the optimal soft-tissue overview (e.g. hyperintense signals reflecting edema/myelomalacia in the cord, CT′s directly demonstrate the ossification of OPLL often "missed" by MR (e.g. documents the single or double layer signs of dural penetration. Patient Selection: Patients with mild myelopathy/cord compression rarely require surgery, while those with moderate/severe myelopathy/cord compression often warrant anterior, posterior, or circumferential approaches. Operative Approaches: Anterior corpectomies/fusions, warranted in patients with OPLL and kyphosis/loss of lordosis, also increase the risks of cerebrospinal fluid (CSF leaks (e.g. single/double layer sign, and vascular injuries (e.g. carotid, vertebral. Alternatively, with an adequate lordosis, posterior procedures (e.g. often with fusions, may provide adequate multilevel decompression while minimizing risk of anterior surgery. Occasionally, combined pathologies may warrant circumferential approaches. Anesthetic and Intraoperative Monitoring Protocols: The utility of awake nasotracheal fiberoptic intubation/awake positioning, intraoperative somatosensory/motor evoked potential, and electromyographic monitoring, and the requirement for total intravenous anesthesia (TIVA for OPLL surgery is also discussed. Conclusion: Anterior, posterior, or circumferential surgery may be warranted to treat patients with cervical OPLL, and must be based on careful patient selection, and both MR and CT documentation of the full extent of OPLL.

    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.

    Intraoperative x-ray radiography/fluoroscopy is commonly used to assess the placement of surgical devices in the operating room (e.g. spine pedicle screws), but qualitative interpretation can fail to reliably detect suboptimal delivery and/or breach of adjacent critical structures. We present a 3D-2D image registration method wherein intraoperative radiographs are leveraged in combination with prior knowledge of the patient and surgical components for quantitative assessment of device placement and more rigorous quality assurance (QA) of the surgical product. The algorithm is based on known-component registration (KC-Reg) in which patient-specific preoperative CT and parametric component models are used. The registration performs optimization of gradient similarity, removes the need for offline geometric calibration of the C-arm, and simultaneously solves for multiple component bodies, thereby allowing QA in a single step (e.g. spinal construct with 4-20 screws). Performance was tested in a spine phantom, and first clinical results are reported for QA of transpedicle screws delivered in a patient undergoing thoracolumbar spine surgery. Simultaneous registration of ten pedicle screws (five contralateral pairs) demonstrated mean target registration error (TRE) of 1.1  ±  0.1 mm at the screw tip and 0.7  ±  0.4° in angulation when a prior geometric calibration was used. The calibration-free formulation, with the aid of component collision constraints, achieved TRE of 1.4  ±  0.6 mm. In all cases, a statistically significant improvement (p  <  0.05) was observed for the simultaneous solutions in comparison to previously reported sequential solution of individual components. Initial application in clinical data in spine surgery demonstrated TRE of 2.7  ±  2.6 mm and 1.5  ±  0.8°. The KC-Reg algorithm offers an independent check and quantitative QA of the surgical product using radiographic/fluoroscopic views

    Purpose: Deformable registration of preoperative and intraoperative images facilitates accurate localization of target and critical anatomy in image-guided spine surgery. However, conventional deformable registration fails to preserve the morphology of rigid bone anatomy and can impart distortions that confound high-precision intervention. We propose a constrained registration method that preserves rigid morphology while allowing deformation of surrounding soft tissues. Method: The registration method aligns preoperative 3D CT to intraoperative cone-beam CT (CBCT) using free-form deformation (FFD) with penalties on rigid body motion imposed according to a simple intensity threshold. The penalties enforced 3 properties of a rigid transformation - namely, constraints on affinity (AC), orthogonality (OC), and properness (PC). The method also incorporated an injectivity constraint (IC) to preserve topology. Physical experiments (involving phantoms, an ovine spine, and a human cadaver) as well as digital simulations were performed to evaluate the sensitivity to registration parameters, preservation of rigid body morphology, and overall registration accuracy of constrained FFD in comparison to conventional unconstrained FFD (denoted uFFD) and Demons registration. Result: FFD with orthogonality and injectivity constraints (denoted FFD+OC+IC) demonstrated improved performance compared to uFFD and Demons. Affinity and properness constraints offered little or no additional improvement. The FFD+OC+IC method preserved rigid body morphology at near-ideal values of zero dilatation (D = 0.05, compared to 0.39 and 0.56 for uFFD and Demons, respectively) and shear (S = 0.08, compared to 0.36 and 0.44 for uFFD and Demons, respectively). Target registration error (TRE) was similarly improved for FFD+OC+IC (0.7 mm), compared to 1.4 and 1.8 mm for uFFD and Demons. Results were validated in human cadaver studies using CT and CBCT images, with FFD+OC+IC providing excellent preservation

    Intraoperative spinal cord monitoring consists in a subcontinuous evaluation of spinal cord sensory-motor functions and allows the reduction the incidence of neurological complications resulting from spinal surgery. A combination of techniques is used: somatosensory evoked potentials (SSEP), motor evoked potentials (MEP), neurogenic motor evoked potentials (NMEP), D waves, and pedicular screw testing. In absence of intraoperative neurophysiological testing, the intraoperative wake-up test is a true form of monitoring even if its latency long and its precision variable. A 2011 survey of 117 French spinal surgeons showed that only 36% had neurophysiological monitoring available (public healthcare facilities, 42%; private facilities, 27%). Monitoring can be performed by a neurophysiologist in the operating room, remotely using a network, or directly by the surgeon. Intraoperative alerts allow real-time diagnosis of impending neurological injury. Use of spinal electrodes, moved along the medullary canal, can determine the lesion level (NMEP, D waves). The response to a monitoring alert should take into account the phase of the surgical intervention and does not systematically lead to interruption of the intervention. Multimodal intraoperative monitoring, in presence of a neurophysiologist, in collaboration with the anesthesiologist, is the most reliable technique available. However, no monitoring technique can predict a delayed-onset paraplegia that appears after the end of surgery. In cases of preexisting neurological deficit, monitoring contributes little. Monitoring of the L1-L4 spinal roots also shows low reliability. Therefore, monitoring has no indication in discal and degenerative surgery of the spinal surgery. However, testing pedicular screws can be useful. All in all, thoracic and thoracolumbar vertebral deviations, with normal preoperative neurological examination are currently the essential indication for spinal cord monitoring. Its absence in this

    A myriad of negative bodily health effects related to tobacco smoking is known while its detrimental effects on the spine in particular are less defined. The goal of the current study is to compare long-term outcome between smokers and non-smokers after non-instrumented lumbar spine surgery. Prospective observational study on n=172 consecutive patients undergoing non-instrumented spine surgery for lumbar disc herniation (LDH) or lumbar spinal stenosis (LSS) with a follow-up (FU) of 4.5 years. Patients were dichotomized according to their smoking status at the time of surgery. Back pain and health-related quality of life (HRQoL) were assessed using the visual analogue scale (VAS) and the Short-Form (SF)-12. Any subsequent lumbar spine surgeries since the index surgery were registered. Logistic regression analysis was used to estimate the effect size of the relationship between smoking and the responder status to surgery in terms of pain and HRQoL-metrics. Complete FU data was available for n=29 (55%) smokers and n=75 (63%) non-smokers. At discharge, 1 month, 1 year and 4.5 years, smokers were as likely as non-smokers to achieve a favourable response to surgery in terms of VAS back pain and the SF-12 mental and physical component scale metric. A subgroup analysis on active smokers throughout the entire study interval did not find an inferior responder rate than in never-smokers. A trend for additional lumbar spine surgery performed in 17.2% of the smoking and 8.2% of the non-smoking patients during FU was observed (OR 2.39, 95% CI 0.67-8.57, p=0.179). Up to 4.5 years following non-instrumented lumbar spine surgery, there was no difference in the pain or HRQoL-responder status of smokers and non-smokers. Smokers may be more likely to undergo re-do surgery in the long term, but more data is needed to confirm this statistical trend. Copyright © 2016 Elsevier B.V. All rights reserved.

    Patients undergoing spinal surgeries may develop postoperative visual loss. We present a case of total bilateral visual loss in a patient who, despite having clinical and surgical risk factors for organic lesion, evolved with visual disturbance due to conversion disorder. A male patient, 39 years old, 71kg, 1.72 m, ASA I, admitted to undergo fusion and discectomy at L4-L5 and L5-S1. Venoclysis, cardioscopy, oximetry, NIBP; induction with remifentanil, propofol and rocuronium; intubation with ETT (8.0mm) followed by capnography and urinary catheterization for diuresis. Maintenance with full target-controlled intravenous anesthesia. During fixation and laminectomy, the patient developed severe bleeding and hypovolemic shock. After 30minutes, hemostasis and hemodynamic stability was achieved with infusion of norepinephrine, volume expansion, and blood products. In the ICU, the patient developed mental confusion, weakness in the limbs, and bilateral visual loss. It was not possible to identify clinical, laboratory or image findings of organic lesion. He evolved with episodes of anxiety, emotional lability, and language impairment; the hypothesis of conversion syndrome with visual component was raised after psychiatric evaluation. The patient had complete resolution of symptoms after visual education and introduction of low doses of antipsychotic, antidepressant, and benzodiazepine. Other symptoms also regressed, and the patient was discharged 12 days after surgery. After 60 days, the patient had no more symptoms. Conversion disorders may have different signs and symptoms of non-organic origin, including visual component. It is noteworthy that the occurrence of this type of visual dysfunction in the postoperative period of spinal surgery is a rare event and should be remembered as a differential diagnosis.

    Pneumocephalus is a collection of air within in the intracranial cavity, most commonly seen following traumatic injury or cranial surgeries. Esophageal injury and cerebrospinal fluid (CSF) leak are rare complications that may occur following anterior cervical discectomy and fusion (ACDF). We present a novel case of pneumocephalus arising from unrestricted leakage of CSF via coincident esophageal injury and durotomy in a patient who underwent an ACDF after trauma. A 21-year-old man presented to an outside hospital with C5/C6 subluxation, complete spinal cord injury, and quadriplegia from a motor vehicle accident. He underwent an ACDF, during which a CSF leak was observed. He was then transferred to our institution for rehabilitation and tracheostomy placement 1 week after the ACDF surgery. Following the tracheostomy, the patient developed intractable fevers and nonspecific symptoms. A CT scan demonstrated frontal pneumocephalus without mass effect. Air was found in the retropharyngeal space. There were no accumulations of CSF in the neck. Extravasation of contrast around instrumentation at C5/C6 on a cine esophagogram demonstrated an esophageal perforation at that level. Pneumocephalus may form when large volumes of CSF escape from the intracranial space and air is drawn into the space by the negative pressure. In this unusual case, the esophageal perforation promoted the formation of the pneumocephalus. Treatment included closure of both defects, disrupting the suspected communication between the intracranial space and the esophagus. Published by Elsevier Ltd.

    Retrospective analysis of prospectively collected data. The aim of this study was to determine whether 1-year patient-reported outcomes (PROs) can accurately assess effective care for patients undergoing surgery for degenerative lumbar spine disease. Prospective longitudinal PROs registries provide a means to accurately assess outcomes and determine the relative effectiveness of various spine treatments. Obtaining long-term PROs can be costly and challenging. Patients enrolled into a prospective registry who underwent lumbar spine surgery for degenerative disease were included. Baseline, 1-year, and 2-year Oswestry Disability Index (ODI) scores were captured. Previously published minimum clinically important difference (MCID) for ODI (14.9) was used. Multivariable linear regression model was created to derive model-estimated 2-year ODI scores. Absolute differences between 1-year and 2-year ODI were compared to absolute differences between 2-year and model-estimated 2-year ODI. Concordance rates in achieving MCID at 1-year and 2-year and predictive values were calculated. A total of 868 patients were analyzed. One-year ODI scores differed from 2-year scores by an absolute difference of 9.7 ± 8.9 points and predictive model-estimated 2-year scores differed from actual 2-year scores by 8.8 ± 7.3 points. The model-estimated 2-year ODI was significantly different than actual 1-year ODI in assessing actual 2-year ODI for all procedures (P = 0.001) except for primary (P = 0.932) and revision microdiscectomy (P = 0.978) and primary laminectomy (P = 0.267). The discordance rates of achieving or not achieving MCID for ODI ranged from 8% to 27%. Concordance rate was about 90% for primary and revision microdiscectomy. The positive and negative predictive value of 1-year ODI to predict 2-year ODI was 83% and 67% for all procedures and 92% and 67% for primary and 100% and 86% for revision microdiscectomy respectively.

  16. Bariatric bypasses contribute to loss of bone mineral density but reduce axial back pain in morbidly obese patients considering spine surgery

    Science.gov (United States)

    Epstein, Nancy E.

    2017-01-01

    Background: Many spine surgeons recommend stringent weight loss, including bariatric bypass procedures, prior to “elective” spine surgery (should not be for axial back pain alone) in morbidly obese patients (defined by a body mass index (BMI) of >40 mg/kg2 or >35 mg/kg2 with two or more major comorbidities) to reduce their greater risk for major perioperative complications. Although bypasses typically lead to marked weight reduction and even reduced axial back pain, they also promote unrecognized and often insufficiently treated vitamin D deficiency and loss of bone mineral density. Methods: Morbidly obese patients who are under consideration for “elective” spine operations (other than for back pain alone) are often told to lose weight. Some choose to undergo bariatric bypass procedures, but are unaware of the potential risks/complications of these procedures. Results: Within the first 2 years following most bariatric bypass procedures, patients experience not only marked loss of weight and muscle mass, but also significant vitamin D deficiency and loss of bone mineral density, increasing their susceptibility to fractures. Nevertheless, some patients also experience a sufficient reduction of axial back pain to avoid spinal surgery. Conclusions: Morbidly obese patients under consideration for “elective” spine surgery may undergo bariatric bypass procedures that lead to a significant reduction of vitamin D levels and loss of bone mineral density. However, potential benefits may include a sufficient reduction of axial back pain to avoid surgery in a select subset of patients altogether. PMID:28217392

    Localization of target vertebrae is an essential step in minimally invasive spine surgery, with conventional methods relying on "level counting" - i.e., manual counting of vertebrae under fluoroscopy starting from readily identifiable anatomy (e.g., the sacrum). The approach requires an undesirable level of radiation, time, and is prone to counting errors due to the similar appearance of vertebrae in projection images; wrong-level surgery occurs in 1 of every ~3000 cases. This paper proposes a method to automatically localize target vertebrae in x-ray projections using 3D-2D registration between preoperative CT (in which vertebrae are preoperatively labeled) and intraoperative fluoroscopy. The registration uses an intensity-based approach with a gradient-based similarity metric and the CMA-ES algorithm for optimization. Digitally reconstructed radiographs (DRRs) and a robust similarity metric are computed on GPU to accelerate the process. Evaluation in clinical CT data included 5,000 PA and LAT projections randomly perturbed to simulate human variability in setup of mobile intraoperative C-arm. The method demonstrated 100% success for PA view (projection error: 0.42mm) and 99.8% success for LAT view (projection error: 0.37mm). Initial implementation on GPU provided automatic target localization within about 3 sec, with further improvement underway via multi-GPU. The ability to automatically label vertebrae in fluoroscopy promises to streamline surgical workflow, improve patient safety, and reduce wrong-site surgeries, especially in large patients for whom manual methods are time consuming and error prone.

    To evaluate the degree to which conservative care and failure were specifically defined in studies comparing nonoperative treatment versus surgery for low back pain (LBP) conditions in adults. A comprehensive literature search was conducted by an experienced librarian using MEDLINE (PubMed), Embase, Google Scholar, and CENTRAL from January 2003 to June 2014. Endnote bibliographic management application was used to remove duplicates and organize the citations. Prospective, randomized, or cohort trials comparing surgery versus conservative intervention for patients with LBP conditions. Study selection was conducted by 2 independent reviewers. Three independent reviewers extracted data from each article using a structured data extraction form. Data extracted included type of study, participant characteristics, sample size, description, and duration of conservative care and whether failed conservative care criterion was defined. A total of 852 unique records were screened for eligibility; of those, 72 articles were identified for further full-text review. Thirty-four full texts were excluded based on the exclusion criteria, and 38 articles, representing 20 unique studies, were included for qualitative synthesis. Fifteen of the 20 studies defined the duration of conservative care. Only 3 studies defined the dosage of physical therapy sessions, including total number of visits and visit duration. Two studies described medication usage, including the duration and type. No studies specifically defined what constituted failed conservative therapy. This literature review suggests conservative care is poorly defined in randomized trials, which can lead to ambiguity of research procedures and unclear guidelines for clinicians. Future studies should increase transparency and explicitly define conservative care. Copyright © 2016 American Congress of Rehabilitation Medicine. All rights reserved.

    Study for feasibility of commercially available action cameras in recording video of spine. Recent innovation of the wearable action camera with high-definition video recording enables surgeons to use camera in the operation at ease without high costs. The purpose of this study is to compare the feasibility, safety, and efficacy of commercially available action cameras in recording video of spine surgery. There are early reports of medical professionals using Google Glass throughout the hospital, Panasonic HX-A100 action camera, and GoPro. This study is the first report for spine surgery. Three commercially available cameras were tested: GoPro Hero 4 Silver, Google Glass, and Panasonic HX-A100 action camera. Typical spine surgery was selected for video recording; posterior lumbar laminectomy and fusion. Three cameras were used by one surgeon and video was recorded throughout the operation. The comparison was made on the perspective of human factor, specification, and video quality. The most convenient and lightweight device for wearing and holding throughout the long operation time was Google Glass. The image quality; all devices except Google Glass supported HD format and GoPro has unique 2.7K or 4K resolution. Quality of video resolution was best in GoPro. Field of view, GoPro can adjust point of interest, field of view according to the surgery. Narrow FOV option was the best for recording in GoPro to share the video clip. Google Glass has potentials by using application programs. Connectivity such as Wi-Fi and Bluetooth enables video streaming for audience, but only Google Glass has two-way communication feature in device. Action cameras have the potential to improve patient safety, operator comfort, and procedure efficiency in the field of spinal surgery and broadcasting a surgery with development of the device and applied program in the future.

    Medicine has experienced greater scientific and technological advances in the last 50 years than in the rest of human history. The article describes relevant events, revises concepts and advantages and clinical applications, summarizes published clinical results, and presents some personal reflections without giving dogmatic conclusions about robotic surgery. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) defines robotic surgery as a surgical procedure using technology to aid the interaction between surgeon and patient. The objective of the surgical robot is to correct human deficiencies and improve surgical skills. The capacity of repeating tasks with precision and reproducibility has been the base of the robot´s success. Robotic technology offers objective and measurable advantages: - Improving maneuverability and physical capacity during surgery. - Correcting bad postural habits and tremor. - Allowing depth perception (3D images). - Magnifying strength and movement limits. - Offering a platform for sensors, cameras, and instruments. Endoscopic surgery transformed conceptually the way of practicing surgery. Nevertheless in the last decade, robotic assisted surgery has become the next paradigm of our era.

    The WHO describes health as physical, mental and social well being. Ever since the establishment of plastic surgery aesthetic surgery has been an integral part of this medical specialty. It aims at reconstructing subjective well-being by employing plastic surgical procedures as described in the educational code and regulations for specialists of plastic surgery. This code confirms that plastic surgery comprises cosmetic procedures for the entire body that have to be applied in respect of psychological exploration and selection criteria. A wide variety of opinions resulting from very different motivations shows how difficult it is to differentiate aesthetic surgery as a therapeutic procedure from beauty surgery as a primarily economic service. Jurisdiction, guidelines for professional conduct and ethical codes have tried to solve this question. Regardless of the intention and ability of the health insurances, it has currently been established that the moral and legal evaluation of advertisements for medical procedures depends on their purpose: advertising with the intent of luring patients into cosmetic procedures that do not aim to reconstruct a subjective physical disorder does not comply with a medical indication. If, however, the initiative originates with the patient requesting the amelioration of a subjective disorder of his body, a medical indication can be assumed.

    Full Text Available Solitary plasmacytoma of bone is a rare malignant tumor mostly involving the axial skeleton. The tumor occurs in middle- aged or elderly people (mean age: 55 years and has a high risk of progression to multiple myeloma. Radiotherapy is the preferred treatment for this disease. We report a case of recurrent solitary plasmacytoma of the fourth lumbar vertebra in a 35-year-old male. The patient suffered from intractable pain due to a pathologic fracture and instability. We performed two-stage posterior and anterior surgical procedures on him. Our method was useful for immediate pain relief and early return to activity, spinal decompression and biomechanical stabilization of the involved vertebra. Afterward, the patient underwent radiotherapy as the adjuvant therapy. The patient is asymptomatic without any recurrenceafter a one-year follow up. We recommend surgery as an appropriate option for patients with intractable pain as a result of pathologic fracture, vertebral instability, neurological compromise, failure of radiotherapy or a combination of these disorders.

    Although spinal infections have always been present recently their incidence has increased, in partly fostered by the advances in medicine (i.e. compromised 10 immunity, chronic diseases, increasingly complex spinal procedures...) and increased life expectancy. Using PubMed for this systematic review, the main spine infections types will be addressed focusing in the minimally invasive surgical techniques that can be used in their treatment. Spontaneous and iatrogenic pyogenic and non-pyogenic spine infections can be treated in many different ways depending on their extension and 15 location as well as on their causative microorganisms. The indications of percutaneous image-guided, endoscopic and microsurgical treatment techniques will be updated. In spine infections minimally invasive surgical techniques show a great potential as to be safe, effective, with low surgical morbidity and fast patients' recovery.

    As the life span and proportion of people over 65 years increase, the incidence of degenerative lumbar spine stenosis grows proportionally. Various parameters of the spinopelvic relationships are used to predict surgical treatment outcomes in patients with degenerative spine diseases. There are no unified protocols for evaluation, in terms of the sagittal balance, of surgical treatment outcomes in elderly patients. To study the impact of sagittal balance parameters on the life quality of elderly and senile patients after surgery for degenerative stenosis of the lumbar spine. The study included 109 patients. Decompression was performed in the first group of 53 patients. Decompression and stabilization were performed in the second group of 27 patients. In the third group of 29 patients, XLIF indirect decompression, scoliosis correction, reconstruction of disturbed spinopelvic relationships, and stabilization were carried out. We evaluated the following sagittal balance parameters: pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), lumbar lordosis (LL), and PI minus LL (PI-LL). The quality of life indicators were assessed using VAS, ODI, and SF36 scores. In the first group, there were not statistically significant differences for PT≤20° and PT>20°. A statistically significant change in the PI-LL parameter (p=0.0263) was in the first group. A decrease in PI-LL was accompanied by regression of pain (p20° as well as PI-LL≤10° and PI-LL>10 in the postoperative period. In the third group, postoperative improvement in PT (p=0.0002) and PI-LL (p=0.0008) parameters was accompanied by a decrease in pain in the legs (p=0.0002) and lumbar spine (p=0.0001). Improvement in the quality of life indicators in 48.6% of cases was achieved by decompression only; the sagittal balance parameters had no significant impact on quality of life. In 24.8% of cases, improvement in the quality of life indicators was achieved by decompression and stabilization because the dominant

    Proficiency in minimally invasive surgery requires intensive and continuous training, as it is technically challenging for unnatural visual and haptic perceptions. Robotic and computer sciences are producing innovations to augment the surgeon's skills to achieve accuracy and high precision during complex surgery. This article reviews the current use of robotically assisted surgery, focusing on technology as well as main applications in digestive surgery, and future perspectives. The PubMed database was interrogated to retrieve evidence-based data on surgical applications. Internal and external consulting with key opinion leaders, renowned robotics laboratories and robotic platform manufacturers was used to produce state-of-the art business intelligence around robotically assisted surgery. Selected digestive procedures (oesophagectomy, gastric bypass, pancreatic and liver resections, rectal resection for cancer) might benefit from robotic assistance, although the current level of evidence is insufficient to support widespread adoption. The surgical robotic market is growing, and a variety of projects have recently been launched at both academic and corporate levels to develop lightweight, miniaturized surgical robotic prototypes. The magnified view, and improved ergonomics and dexterity offered by robotic platforms, might facilitate the uptake of minimally invasive procedures. Image guidance to complement robotically assisted procedures, through the concepts of augmented reality, could well represent a major revolution to increase safety and deal with difficulties associated with the new minimally invasive approaches. © 2015 BJS Society Ltd.

    Retrospective database analysis. The impact of the 2008-2009 economic downtown on elective lumbar spine surgery is unknown. Our objective was to investigate the effect of the economic downturn on the overall trends of elective lumbar spine surgery in the United States. The Nationwide Inpatient Sample (NIS) was used in conjunction with US Census and macroeconomic data to determine historical trends. The economic downturn was defined as 2008 to 2009. Codes from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), were used in order to identify appropriate procedures. Confidence intervals were determined using subgroup analysis techniques. From 2003 to 2012, there was a 19.8% and 26.1% decrease in the number of lumbar discectomies and laminectomies, respectively. Over the same time period, there was a 56.4% increase in the number of lumbar spinal fusions. The trend of elective lumbar spine surgeries per 100 000 persons in the US population remained consistent from 2008 to 2009. The number of procedures decreased by 4.5% from 2010 to 2011, 7.6% from 2011 to 2012, and 3.1% from 2012 to 2013. The R(2) value between the number of surgeries and the S&P 500 Index was statistically significant (P ≤ .05). The economic downturn did not affect elective lumbar fusions, which increased in total from 2003 to 2013. The relationship between the S&P 500 Index and surgical trends suggests that during recessions, individuals may utilize other means, such as insurance, to cover procedural costs and reduce out-of-pocket expenditures, accounting for no impact of the economic downturn on surgical trends. These findings can assist multiple stakeholders in better understanding the interconnectedness of macroeconomics, policy, and elective lumbar spine surgery trends.

    Full Text Available Background: Although fibrin sealants (FSs and fibrin glues (FGs are predominantly utilized to strengthen repairs of cerebrospinal fluid (CSF fistulas (deliberate/traumatic during spinal surgery, they are also increasingly utilized to achieve hemostasis. Here, we investigated whether adding Tisseel (Baxter International Inc., Westlake Village, CA, USA, utilized to address increased bleeding during multilevel lumbar laminectomies with non-instrumented fusions, would reduce or equalize the time to drain removal and length of stay (LOS without contributing to infections or prolonging time to fusion. Methods: Prospectively, 39 patients underwent multilevel laminectomies and 1-2 level non-instrumented (in situ fusions to address stenosis/olisthesis; 22 who demonstrated increased intraoperative bleeding received Tisseel, while 17 without such bleeding did not. Results: The 22 receiving versus 17 not receiving Tisseel, with similar clinical parameters, underwent comparable average multilevel laminectomies (4.36 and 4.25 and 1-2 level fusions (1.4 vs. 1.29 levels. As anticipated, for those receiving Tisseel, the average intraoperative estimated blood loss (EBL, total postoperative blood loss, and total perioperative transfusion requirements [red blood cells (RBC, fresh frozen plasma (FFP, platelets] were higher. However, Tisseel had the added benefit of equalizing the time to postoperative drain removal [e.g. 3.41 days (with vs. 3.38 days (without] and LOS [e.g. 5.86 days (with vs. 5.82 days (without] without increasing the infection rates (e.g. one superficial infection per group or average times to fusion (e.g. 5.9 vs. 5.5 months. Conclusions: Adding Tisseel for increased bleeding during multilevel laminectomies/in situ fusions contributed to hemostasis by equalizing the average times to drain removal/LOS compared to patients without increased bleeding and not requiring Tisseel.

    Modern medicine, which is evidence-based and overly scientific, has forgotten its artistic component, which is very important for surgery in general and for geriatric surgery in particular. The surgeon treating an old patient must be a politician more than a technician, more an artist than a scientist. Like Leonardo da Vinci, he or she must use scientific knowledge with intelligence and sensitivity, transforming the elderly patient's last days of life into a beautiful and harmonious painting and not into something like an atomic power station which, while no doubt useful, is deprived of beauty and sometimes very dangerous.

    Of patients who have undergone lateral approaches to the thoracic spine, surgical site postoperative pain appears to be greater among those who have undergone transection and removal of a rib segment than those who have not. Therefore, techniques that conserve anatomical position and minimize tissue disruption would theoretically result in less pain and a quicker recovery. Herein, we describe a rib-sparing osteoplastic technique used when rib segments need to be displaced in order to create an unobscured corridor to the operative target. Our approach minimizes soft tissue disruption and restores the anatomical function of the rib. Based on our experience, these patients report less pain, mobilize earlier, and are discharged sooner than those who have had rib segments sacrificed as part of a lateral approach to the spine.

      Spine fusion technique has been the most frequently used technique in the treatment of degenerative spinal diseases. However, various related complications force doctors to look for other substitutions. The proposing and application of non-fusion technique has changed the concept of traditional spine surgery. A great number of early and present researches have revealed good results, nevertheless, the results vary due to the deficiency of high-quality clinical researches. The definite conclusion can hardly be drawn, while the technique should be used cautiously.

    Kaulhausen Thomas

    2011-10-01

    Full Text Available Abstract Background Fusion of lumbar spine segments is a well-established therapy for many pathologies. The procedure changes the biomechanics of the spine. Initial clinical benefits may be outweighed by ensuing damage to the adjacent segments. Various surgical devices and techniques have been developed to prevent this deterioration. "Topping off" systems combine rigid fusion with a flexible pedicle screw system to prevent adjacent segment disease (ASD. To date, there is no convincing evidence that these devices provide any patient benefits. Methods/Design The study is designed as a randomized, therapy-controlled trial in a clinical care setting at a university hospital. Patients presenting to the outpatient clinic with degenerative disc disease or spondylolisthesis will be assessed against study inclusion and exclusion criteria. After randomization, the control group will undergo conventional fusion. The intervention group will undergo fusion with a supplemental flexible pedicle screw system to protect the adjacent segment ("topping off". Follow-up examination will take place immediately after treatment during hospital stay, after 6 weeks, and then after 6, 12, 24 and 36 months. Subsequently, ongoing assessments will be performed annually. Outcome measurements will include quality of life and pain assessments using questionnaires (SF-36™, ODI, COMI. In addition, clinical and radiologic ASD, work-related disability, and duration of work disability will be assessed. Inpatient and 6-month mortality, surgery-related data (e.g., intraoperative complications, blood loss, length of incision, surgical duration, postoperative complications, adverse events, and serious adverse events will be documented and monitored throughout the study. Cost-effectiveness analysis will also be provided. Discussion New hybrid systems might improve the outcome of lumbar spine fusion.

    Arts, Mark P; Rettig, Thijs C D; de Vries, Jessica; Wolfs, Jasper F C; in't Veld, Bas A

    2013-09-25

    In anterior cervical spine surgery a retractor is obligatory to approach the spine. Previous studies showed an increase of endotracheal tube cuff pressure after placement of a retractor. It is known that high endotracheal tube cuff pressure increases the incidence of postoperative dysphagia, hoarseness, and sore throat. However, until now no evidence supports the fact whether adjusting the endotracheal tube cuff pressure during anterior cervical spine surgery will prevent this comorbidity. We present the design of a randomized controlled trial to determine whether adjusting endotracheal tube cuff pressure after placement of a retractor during anterior cervical spine surgery will prevent postoperative dysphagia. 177 patients (aged 18-90 years) scheduled for anterior cervical spine surgery on 1 or more levels will be included. After intubation, endotracheal tube cuff pressure is manually inflated to 20 mm Hg in all patients. Patients will be randomized into two groups. In the control group endotracheal tube cuff pressure is not adjusted after retractor placement. In the intervention group endotracheal tube cuff pressure after retractor placement is maintained at 20 mm Hg and air is withdrawn when cuff pressure exceeds 20 mm Hg. Endotracheal tube cuff pressure is measured after intubation, before and after placement and removal of the retractor. Again air is inflated if cuff pressure sets below 20 mmHg after removal of the retractor. The primary outcome measure is postoperative dysphagia. Other outcome measures are postoperative hoarseness, postoperative sore throat, degree of dysphagia, length of hospital stay, and pneumonia. The study is a single centre double blind randomized trial in which patients and research nurses will be kept blinded for the allocated treatment during the follow-up period of 2 months. Postoperative dysphagia occurs frequently after anterior cervical spine surgery. This may be related to high endotracheal tube cuff pressure. Whether

    Percutaneous endoscopic spine surgery differs from other minimally invasive spinal techniques because of use of the spinal endoscope. With the development and improvement of endoscopic optical technology, endoscopic surgical techniques and instrumentation, central, paracentral, foraminal and far lateral lumbar disc herniation can now be treated by endoscopic techniques. Endoscopic systems are also used for posterior interlaminar lumbar decompression, anterior and posterior cervical discectomy. Some unilevel lumbar stenosis may be treated by the endoscopic techniques as well. Although the surgical indications for endoscopic techniques are evolving, there are many potential complications, such as nerve root injury, durotomy, infection, retro-peritoneal cavity injury, cauda equine injury, great vessel injury, muscular hematoma, re-herniation, piriformis syndrome, and/or epidural hematoma. So, the endoscopic spine surgery can only be practiced after the completion of learning curve which could be improved through training, mentorship and clinic surgical experience. Surgical training, including didactic lectures, hands on cadaveric training, and surgical observation, should all be essential for surgical education and instruction. Appropriate preoperative planning and strictly controlled indications of percutaneous endoscopic spine surgery are necessary and important for optimal outcomes.

    Full Text Available BACKGROUND: Spine surgeries may involve uncontrolled bleeding, resulting primarily from large vein and persists even after the wound is closed. Proper patient positioning, use of hypotensive anaesthesia regimen and normothermia reduces blood loss, additional measures to reduce bleeding & transfusion requirement must be considered in spine surgery. MATERIALS AND METHODS: Forty patients of both sexes between the age group 21 to 60 years belonging to ASA I to III who were scheduled for spine stabilization surgeries was enrolled for the study were randomized into two groups with 20 in each. Anaesthetic technique was standardized. Group T received Tranexamic acid bolus of 10 mg/kg i.v. over 15 min. after patient positioning followed maintenance infusion of 1mg/kg/hr. And Group N Equivalent volume of Normal saline. Intra-operative blood losses was measured by weighing sponges, measuring suction drainage and estimates of blood loss on the surgical drapes and gowns by the attending anesthesiologist. Post-operative blood losses were assessed by measuring wound drainage until drains withdrawal. Investigations like Hb, Platelet, PT and APTT were done pre and post-operatively. Patients were assessed postoperatively daily for any clinical evidence of deep venous thrombosis.

    Surgical removal of a symptomatic herniated lumbar disc is performed either with or without the support of a microscope. Up to the time of writing, the literature has reported similar clinical outcomes for the two procedures. Five hundred consecutive patients, operated upon for primary single-level lumbar disc herniation in our University Spine Center between 2003-2011, with (n=275), or without (n=225), the aid of a microscope were included. Data were retrospectively analyzed, comparing the primary endpoint of clinical outcome and the secondary endpoints of complications, surgical time and length of hospitalization. Clinical outcomes and reoperation rates were comparable in both groups. Surgical time was significantly shorter with a mean time of 47minutes without use of the microscope compared to the mean time of 87minutes (plumbar disc herniation is associated with similar clinical outcomes and reoperation rates. Open sequestrectomy is associated with shorter operation times. Microdiscectomy is associated with shorter hospitalization stays.

  14. Reversible coma and Duret hemorrhage after intracranial hypotension from remote lumbar spine surgery: case report.

    Bonow, Robert H; Bales, James W; Morton, Ryan P; Levitt, Michael R; Zhang, Fangyi

    2016-03-01

    Intracranial hypotension is a rare condition caused by spontaneous or iatrogenic CSF leaks that alter normal CSF dynamics. Symptoms range from mild headaches to transtentorial herniation, coma, and death. Duret hemorrhages have been reported to occur in some patients with this condition and are traditionally believed to be associated with a poor neurological outcome. A 73-year-old man with a remote history of spinal fusion presented with syncope and was found to have small subdural hematomas on head CT studies. He was managed nonoperatively and discharged with a Glasgow Coma Scale score of 15, only to return 3 days later with obtundation, fixed downward gaze, anisocoria, and absent cranial nerve reflexes. A CT scan showed Duret hemorrhages and subtle enlargement of the subdural hematomas, though the hematomas remained too small to account for his poor clinical condition. Magnetic resonance imaging of the spine revealed a large lumbar pseudomeningocele in the area of prior fusion. His condition dramatically improved when he was placed in the Trendelenburg position and underwent repair of the pseudomeningocele. He was kept flat for 7 days and was ultimately discharged in good condition. On long-term follow-up, his only identifiable deficit was diplopia due to an internuclear ophthalmoplegia. Intracranial hypotension is a rare condition that can cause profound morbidity, including tonsillar herniation and brainstem hemorrhage. With proper identification and treatment of the CSF leak, patients can make functional recoveries.

    Recovery from spine surgery is oriented toward restoring functional health outcomes while reducing resource use. Optimal pain management is a key to reaching these objectives. We compared outcomes of spine surgery patients who received standard pain management including intravenous (IV) acetaminophen (APAP) vs. oral APAP. We performed a retrospective analysis of the Premier database (January 2012 to September 2015) comparing spine surgery patients who received pain management with IV APAP to those who received oral APAP, with no exclusions based on additional pain management. We performed multivariable logistic regression for the discharge and all cause 30-day readmission to the same hospital outcomes and instrumental variable regressions using the quarterly rate of IV APAP use for all hospitalizations by hospital as the instrument in two-stage least squares regressions for length of stay (LOS), hospitalization costs, and average daily morphine equivalent dose (MED) outcomes. Models adjusted for age, gender, race, admission type, 3M All Patient Refined Diagnosis Related Group severity of illness and risk of mortality, hospital size, and indicators for whether the hospital was an academic center and whether it was urban or rural. We identified 112,586 spine surgery patients with 51,835 (46%) having received IV APAP. Subjects averaged 57 and 59 years of age respectively in the IV APAP and oral APAP cohorts and were predominantly non-Hispanic Caucasians and female. In our adjusted models, IV APAP was associated with 0.68 days shorter LOS (95% CI: -0.76 to -0.59, p < .0001), $1175 lower hospitalization costs (95% CI: -$1611 to -$739, p < .0001), 13 mg lower average daily MED (95% CI: -14 mg to -12 mg, p < .0001), 34% lower risk of discharge to a skilled nursing facility (95% CI: 0.63 to 0.69, p < .0001), and 13% less risk of 30-day readmission (95% CI: 0.73 to 1.03). Compared to oral APAP, managing post-spine-surgery pain with IV APAP is

    A multi-stage image-based 3D-2D registration method is presented that maps annotations in a 3D image (e.g. point labels annotating individual vertebrae in preoperative CT) to an intraoperative radiograph in which the patient has undergone non-rigid anatomical deformation due to changes in patient positioning or due to the intervention itself. The proposed method (termed msLevelCheck) extends a previous rigid registration solution (LevelCheck) to provide an accurate mapping of vertebral labels in the presence of spinal deformation. The method employs a multi-stage series of rigid 3D-2D registrations performed on sets of automatically determined and increasingly localized sub-images, with the final stage achieving a rigid mapping for each label to yield a locally rigid yet globally deformable solution. The method was evaluated first in a phantom study in which a CT image of the spine was acquired followed by a series of 7 mobile radiographs with increasing degree of deformation applied. Second, the method was validated using a clinical data set of patients exhibiting strong spinal deformation during thoracolumbar spine surgery. Registration accuracy was assessed using projection distance error (PDE) and failure rate (PDE  >  20 mm—i.e. label registered outside vertebra). The msLevelCheck method was able to register all vertebrae accurately for all cases of deformation in the phantom study, improving the maximum PDE of the rigid method from 22.4 mm to 3.9 mm. The clinical study demonstrated the feasibility of the approach in real patient data by accurately registering all vertebral labels in each case, eliminating all instances of failure encountered in the conventional rigid method. The multi-stage approach demonstrated accurate mapping of vertebral labels in the presence of strong spinal deformation. The msLevelCheck method maintains other advantageous aspects of the original LevelCheck method (e.g. compatibility with standard clinical workflow, large

    OBJECTIVE Prospective longitudinal outcomes registries are at the center of evidence-driven health care reform. Obtaining real-world outcomes data at 12 months can be costly and challenging. In the present study, the authors analyzed whether 3-month outcome measurements sufficiently represent 12-month outcomes for patients with degenerative lumbar disease undergoing surgery. METHODS Data from 3073 patients undergoing elective spine surgery for degenerative lumbar disease were entered into a prospective multicenter registry (N(2)QOD). Baseline, 3-month, and 12-month follow-up Oswestry Disability Index (ODI) scores were recorded. The absolute differences between actual 12- and 3-month ODI scores was evaluated. Additionally, the authors analyzed the absolute difference between actual 12-month ODI scores and a model-predicted 12-month ODI score (the model used patients' baseline characteristics and actual 3-month scores). The minimal clinically important difference (MCID) for ODI of 12.8 points and the substantial clinical benefit (SCB) for ODI of 18.8 points were used based on the previously published values. The concordance rate of achieving MCID and SCB for ODI at 3-and 12-months was computed. RESULTS The 3-month ODI scores differed from 12-month scores by an absolute difference of 11.9 ± 10.8, and predictive modeling estimations of 12-month ODI scores differed from actual 12-month scores by a mean (± SD) of 10.7 ± 9.0 points (p = 0.001). Sixty-four percent of patients (n = 1982) achieved an MCID for ODI at 3 months in comparison with 67% of patients (n = 2088) by 12 months; 51% (n = 1731) and 61% (n = 1860) of patients achieved SCB for ODI at 3 months and 12 months, respectively. Almost 20% of patients had ODI scores that varied at least 20 points (the point span of an ODI functional category) between actual 3- and 12-month values. In the aggregate analysis of achieving MCID, 77% of patients were concordant and 23% were discordant in achieving or not achieving

    Spinal disorders affect mainly older people and cause pain, paralysis and/or deformities of the trunk and/or extremities, which could eventually disturb locomotive functions. For ensuring safe and high-quality treatment of spinal disorders, in 1987, the Tohoku University Spine Society (TUSS) was established by orthopedic departments in Tohoku University School of Medicine and its affiliated hospitals in and around Miyagi Prefecture. All spine surgeries have been enrolled in the TUSS Spine Registry since 1988. Using the data from this registration system between 1988 and 2012, we demonstrate here the longitudinal changes in surgical trends for spinal disorders in Japan that has rushed into the most advanced "aging society" in the world. In total, data on 56,744 surgeries were retrieved. The number of spinal surgeries has annually increased approximately 4-fold. There was a particular increase among patients aged ≥ 70 years and those aged ≥ 80 years, with a 20- to 90-fold increase. Nearly 90% of the spinal operations were performed for degenerative disorders, with their number increasing approximately 5-fold from 705 to 3,448. The most common disease for surgery was lumbar spinal stenosis (LSS) (35.9%), followed by lumbar disc herniation (27.7%) and cervical myelopathy (19.8%). In 2012, approximately half of the patients with LSS and cervical myelopathy were ≥ 70 years of age. In conclusion, the number of spinal operations markedly increased during the 25-year period, particularly among older patients. As Japan has a notably aged population, the present study could provide a near-future model for countries with aging population.

    Retrospective database review. To evaluate whether microscope use during spine procedures is associated with increased operating room times or increased risk of infection. Operating microscopes are commonly used in spine procedures. It is debated whether the use of an operating microscope increases operating room time or confers increased risk of infection. The American College of Surgeons National Surgical Quality Improvement Program database, which includes data from more than 370 participating hospitals, was used to identify patients undergoing elective spinal procedures with and without the use of an operating microscope for the years 2011 and 2012. Bivariate and multivariate linear regressions were used to test the association between microscope use and operating room times. Bivariate and multivariate logistic regressions were similarly conducted to test the association between microscope use and infection occurrence within 30 days of surgery. A total of 23,670 elective spine procedures were identified, of which 2226 (9.4%) used an operating microscope. The average patient age was 55.1±14.4 years. The average operative time (incision to closure) was 125.7±82.0 minutes.Microscope use was associated with minor increases in preoperative room time (+2.9 min, P=0.013), operative time (+13.2 min, Pmicroscope and nonmicroscope groups for occurrence of any infection, superficial surgical site infection, deep surgical site infection, organ space infection, or sepsis/septic shock, regardless of surgery type. We did not find operating room times or infection risk to be significant deterrents for use of an operating microscope during spine surgery. 3.

    The rapid growth of spine degenerative surgery has led to unrelenting efforts to define and prevent possible complications, the incidence of which is probably higher than that reported and varies according to the region of the spine involved (cervical and thoracolumbar) and the severity of the surgery. Several issues are becoming progressively clearer, such as complication rates in primary versus revision spinal surgery, complications in the elderly, the contribution of minimally invasive surgery to the reduction of complication rate. In this paper the most common surgical complications in degenerative spinal surgery are outlined and discussed.

  1. The role of C2-C7 and O-C2 angle in the development of dysphagia after cervical spine surgery.

    Dysphagia is a known complication of cervical surgery and may be prolonged or occasionally serious. A previous study showed that dysphagia after occipitocervical fusion was caused by oropharyngeal stenosis resulting from O-C2 (upper cervical lordosis) fixation in a flexed position. However, there have been few reports analyzing the association between the C2-C7 angle (middle-lower cervical lordosis) and postoperative dysphagia. The aim of this study was to analyze the relationship between cervical lordosis and the development of dysphagia after anterior and posterior cervical spine surgery (AC and PC). Three hundred fifty-four patients were reviewed in this retrospective clinical study, including 172 patients who underwent the AC procedure and 182 patients who had the PC procedure between June 2007 and May 2010. The presence and duration of postoperative dysphagia were recorded via face-to-face questioning or telephone interview performed at least 1 year after the procedure. Plain cervical radiographs before and after surgery were collected. The O-C2 angle and the C2-C7 angle were measured. Changes in the O-C2 angle and the C2-C7 angle were defined as dO-C2 angle = postoperative O-C2 angle - preoperative O-C2 angle and dC2-C7 angle = postoperative C2-C7 angle - preoperative C2-C7 angle. The association between postoperative dysphagia with dO-C2 angle and dC2-C7 angle was studied. Results showed that 12.8 % of AC and 9.4 % of PC patients reported dysphagia after cervical surgery. The dC2-C7 angle has considerable impact on postoperative dysphagia. When the dC2-C7 angle is greater than 5°, the chance of developing postoperative dysphagia is significantly greater. The dO-C2 angle, age, gender, BMI, operative time, blood loss, procedure type, revision surgery, most cephalic operative level, and number of operative levels did not significantly influence the incidence of postoperative dysphagia. No relationship was found between the dC2-C7 angle and the degree of

    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

    Surgery can only maintain its role in a highly competitive environment if results are continuously improved, accompanied by further reduction of the interventional trauma for patients and with justifiable costs. Significant impulse to achieve this goal was expected from minimally invasive surgery and, in particular, robotic surgery; however, a real breakthrough has not yet been achieved. Accordingly, the new strategic approach of cognitive surgery is required to optimize the provision of surgical treatment. A full scale integration of all modules utilized in the operating room (OR) into a comprehensive network and the development of systems with technical cognition are needed to upgrade the current technical environment passively controlled by the surgeon into an active collaborative support system (surgery 4.0). Only then can the true potential of minimally invasive surgery and robotic surgery be exploited.

    Perioperative surgical site infection (SSI) after pediatric spine fusion is a recognized complication with rates between 0.5% and 1.6% in adolescent idiopathic scoliosis and up to 22% in "high risk" patients. Significant variation in the approach to infection prophylaxis has been well documented. The purpose of this initiative is to develop a consensus-based "Best Practice" Guideline (BPG), informed by both the available evidence in the literature and expert opinion, for high-risk pediatric patients undergoing spine fusion. For the purpose of this effort, high risk was defined as anything other than a primary fusion in a patient with idiopathic scoliosis without significant comorbidities. The ultimate goal of this initiative is to decrease the wide variability in SSI prevention strategies in this area, ultimately leading to improved patient outcomes and reduced health care costs. An expert panel composed of 20 pediatric spine surgeons and 3 infectious disease specialists from North America, selected for their extensive experience in the field of pediatric spine surgery, was developed. Using the Delphi process and iterative rounds using a nominal group technique, participants in this panel were as follows: (1) surveyed for current practices; (2) presented with a detailed systematic review of the relevant literature; (3) given the opportunity to voice opinion collectively; and (4) asked to vote regarding preferences privately. Round 1 was conducted using an electronic survey. Initial results were compiled and discussed face-to-face. Round 2 was conducted using the Audience Response System, allowing participants to vote for (strongly support or support) or against inclusion of each intervention. Agreement >80% was considered consensus. Interventions without consensus were discussed and revised, if feasible. Repeat voting for consensus was performed. Consensus was reached to support 14 SSI prevention strategies and all participants agreed to implement the BPG in their

    The presence of diplopia is an undesirable result following strabismus surgery. There are a variety of scenarios where diplopia exists prior to strabismus surgery, and, after surgery, has either been alleviated or decreased to a magnitude amenable to prism correction. In other cases, the patient does not experience diplopia prior to the strabismus surgery, but there exists a definite risk of diplopia after the surgery. In the current review, I examine the literature to help determine the incidence of diplopia after strabismus surgery.

    Several articles have described the use of screw insertion guides during primary spine surgery; however, the use of such a guide during revision surgeries has not been described. The purpose of this study is to describe the utility of a custom screw insertion (CSI) guide assembled using a novel method and a full-scale, color-coded 3D plaster (FCTP) model for safe and accurate revision surgery. The authors applied the CSI guide and the FCTP model in 3 cases. In the first case, a patient with multiple failed cervical spine surgeries underwent occipitocervicothoracic fusion. After a successful result for this patient, the authors applied the CSI guide in 2 other patients who underwent revision lumbar fusion surgeries to confirm the accuracy and the efficacy of the CSI guides in such cases. The models and guides were fabricated using rapid prototyping technology. The effectiveness of these methods was examined. The FCTP model was designed using CT data. During model assembly, implants inserted during previous surgery were removed virtually, and for the cervical spine, vertebral arteries were colored red for planning. The CSI guide was designed with 5 or 6 arms to fit the bone surface precisely after removing artifacts. Surgery was performed by referring to the FCTP model. Because the actual structure of the bone surface was almost identical to that of the FCTP model, surgical exposure around the complex bone shape proceeded smoothly. The CSI guides were positioned accurately to aid the successful insertion of a pedicle screw into the C-2 vertebra in the case of cervical revision surgery, and 4 pedicle screws for lumbar vertebrae in the 2 other patients. Postoperative CT scans showed that all screw positions closely matched those predicted during the preoperative planning. In conclusion, the FCTP models and the novel CSI guides were effective for safe and accurate revision surgery of the spine.

    Adjacent segment disease (ASD) occurs with a probability of 30% in the lumbar spine following spinal fusion surgery. Usually advanced degenerative changes happen cranially to the fused lumbar segment. Thus, secondary spinal instability, stenosis, spodylolisthesis, foraminal stenosis can lead to the recurrence of the pain not always amenable to conservative measures. A typical surgical solution to treat ASD consists of posterior revision surgery including decompression, change or extension of the instrumentation and fusion to the rostral level. It results in a larger operation with considerable risk of complications. We present a typical case of ASD treated surgically with a new minimally invasive method not yet performed in Hungary. We use anterolateral abdominal muscle splitting approach to reach the lumbar spine through the retroperitoneum. A discectomy is performed by retracting the psoas muscle dorsally. The intervertebral bony fusion is achieved by implanting a cage with large volume that is stuffed with autologous bone or tricalcium phosphate. A cage with large volume results in excellent annulus fibrosus tension, immediate stability and provides large surface for bony fusion. A stand-alone cage construct can be supplemented with lateral screw/rod/plate fixation. The advantage of the new technique for the treatment of ASD includes minimal blood loss, short operation time, significantly less postoperative pain and much lower complication rate.

  8. A lumbar disc surgery predictive score card.

    A lumbar disc surgery predictive score card or questionnaire has been developed to assess potential candidates for excision of a herniated lumbar disc who have not previously undergone lumbar spine surgery. It is not designed to encompass patients who are being considered for other types of lumbar spine surgery, such as decompressive laminectomy or fusion. In an effort to make the "score card" usable by almost all physicians who are involved in lumbar disc surgery, only studies which have broad acceptance and are generally employed are included. Studies which have less widespread use such as electromyogram, discogram, venogram, special psychologic studies (MMPI, pain drawings) have been purposely excluded.

    The incidence of surgical site infection (SSI) following posterior cervical surgery has been reported as high as 18% in the literature. Few large studies have specifically examined posterior cervical procedures. The study aims to examine the incidence, timing, and risk factors for SSI following posterior cervical surgery. This is a retrospective cohort study of prospectively collected data in a national surgical outcomes database. The sample includes patients who underwent posterior cervical spine surgery between 2005 and 2012 identified in the American College of Surgeons National Surgical Quality Improvement Project (ACS NSQIP) Participant Use Data File. The 30-day rate of postoperative SSI, timing of diagnosis, and associated risk factors were determined. The ACS NSQIP was used to identify 5,441 patients who underwent posterior cervical spine surgery by Current Procedural Terminology codes from 2005 to 2012. Thirty-day readmission data were obtained for 2011-2012. The incidence and timing of SSI were determined. Multivariable logistic regression analysis was then performed to identify significant risk factors. Of the 5,441 patients identified as having undergone posterior cervical surgery, 3,724 had a posterior cervical decompression, 1,310 had a posterior cervical fusion, and 407 underwent cervical laminoplasty. Surgical site infection within 30 days was identified in 160 patients (2.94%), with 80 of those cases being superficial SSI. There was no significant difference in SSI rate among the three procedure groups. The average time for diagnosis of SSI was over 2 weeks. In 2011-2012, 36.9% of patients with SSI were readmitted within 30 days. Several significant predictors of SSI were identified in univariate analysis, including body mass index (BMI) >35, chronic steroid use, albumin 35 (odds ratio [OR]=1.78, p=.003), chronic steroid use (OR=1.73, p=.049), and operative time >197 minutes (OR=2.08, p=.005), were identified in multivariable analysis.

    OBJECTIVE Primary osteosarcoma of the spine is a rare osseous neoplasm. While previously reported retrospective studies have demonstrated that overall patient survival is impacted mostly by en bloc resection and chemotherapy, the continued management of residual disease remains to be elucidated. This systematic review was designed to address the role of revision surgery and multimodal adjuvant therapy in cases in which en bloc excision is not initially achieved. METHODS A systematic literature search spanning the years 1966 to 2015 was performed on PubMed, Medline, EMBASE, and Web of Science to identify reports describing outcomes of patients who underwent biopsy alone, neurological decompression, or intralesional resection for osteosarcoma of the spine. Studies were reviewed qualitatively, and the clinical course of individual patients was aggregated for quantitative meta-analysis. RESULTS A total of 16 studies were identified for inclusion in the systematic review, of which 8 case reports were summarized qualitatively. These studies strongly support the role of chemotherapy for overall survival and moderately support adjuvant radiation therapy for local control. The meta-analysis revealed a statistically significant benefit in overall survival for performing revision tumor debulking (p = 0.01) and also for chemotherapy at relapse (p osteosarcoma of the spine is neoadjuvant chemotherapy followed by en bloc marginal resection, this objective is not always achievable given anatomical constraints and other limitations at the time of initial clinical presentation. This systematic review supports the continued aggressive use of revision surgery and multimodal adjuvant therapy when possible to improve outcomes in patients who initially undergo subtotal debulking of osteosarcoma. A limitation of this systematic review is that lesions amenable to subsequent resection or tumors inherently more sensitive to adjuvants would exaggerate a therapeutic effect of these

    In the past, the interaction between dentoalveolar surgery and restorative dentistry has been limited to the removal of teeth with pulp and/or periradicular disease or those that were unrestorable. However, with the increasing dental awareness of the population and the retention of teeth into later life, the interaction between dentoalveolar surgery and restorative dentistry is becoming a fundamental aspect of clinical practice. Indeed, endodontic and implant surgery are core activities that facilitate the retention of a functional dentition.

    In the plastic surgery patient population, outpatient surgery is cost effective and will continue to grow as the preferred arena for performing surgery in healthy patients. Although there is a widespread myth that outpatient surgery centers may suffer from increased infection rates due to lax infection control, the data presented from American Association for Accreditation of Ambulatory Surgery Facilities-accredited facilities prove the contrary. There is a lack of data investigating infection prevention in the perioperative period in plastic surgery patients. As data collection becomes more refined, tracking the postoperative care environment should offer additional opportunities to lower the incidence of postoperative infections.

  1. New progress of non-fusion technique in spine surgery%脊柱非融合技术新进展

    2013-01-01

      Spinal fusion has been the golden standard in the treatment of spinal degenerative disease. However, varied related complications make surgeons look for alternative methods. The proposal and application of the concept of non-fusion technique have made a great effect on the development of spine surgery, which includes prosthetic disc nucleus replacement, total disc replacement, pedicle fixation-based dynamic stabilization devices, interspinous process spacers and facet joint replacement devices. This article has retrospectively summarized the latest research. Prosthetic disc nucleus replacement is not recommended due to the early complications. Total disc replacement can be used to restore the intervertebral height to some extent so as to avoid complications related to spine fusion operation, whereas high-quality clinical research is lacked. Pedicle fixation-based dynamic stabilization devices have been focused on, including the Graf ligament system and Dynesys system, and earlier research has shown good clinical results. However, recently more attention is paid to the complications, and the research conclusions vary, furthermore, even are opposite. Until now the definite conclusion can hardly be drawn. Interspinous process spacers mainly include X-STOP and Wallis, which can lower the occurrence rate of adjacent segment degeneration to some extent. However, the latest research has pointed many complications, and interspinous process spacers should be used carefully. As to facet joint replacement devices, the lack of laboratory research and the difficulties in revision have limited their usages.

    A substantial proportion of individuals who undergo surgical procedures to relieve spine pain continue to report significant pain and dysfunction after recovery. Psychopathology and patient expectations have been linked to poor results, leading to an increasing reliance on presurgical psychological screening (PPS) as part of the surgical diagnostic process. The original Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) and the MMPI-2 (Butcher, Graham, Ben-Porath, Tellegen, & Dahlstrom, 2001) were among the measures most commonly used in PPS evaluations and research. This study focuses on the newest version of the test, the MMPI-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011; Tellegen & Ben-Porath, 2008/2011) as a predictor of outcomes for spine surgery candidates. Using a sample of 172 men and 210 women who underwent a PPS, we examined the ability of MMPI-2-RF scale scores to predict early surgical outcomes independent of other presurgical risk factors identified by other means, as well as patients' presurgical expectations. MMPI-2-RF results accounted for up to 11% of additional variance in measures of early postoperative functioning. MMPI-2-RF scales that assess for emotional/internalizing problems, specifically Demoralization, measures of somatoform dysfunction, and interpersonal problems contributed most to the prediction of diminished outcome. 2015 APA, all rights reserved

    Purpose: In image-guided spine surgery, mapping 3D preoperative images to 2D intraoperative images via 3D-2D registration can provide valuable assistance in target localization. However, the presence of surgical instrumentation, hardware implants, and soft-tissue resection/displacement causes mismatches in image content, confounding existing registration methods. Manual/semi-automatic methods to mask such extraneous content is time consuming, user-dependent, error prone, and disruptive to clinical workflow. We developed and evaluated 2 novel similarity metrics within a robust registration framework to overcome such challenges in target localization. Methods: An IRB-approved retrospective study in 19 spine surgery patients included 19 preoperative 3D CT images and 50 intraoperative mobile radiographs in cervical, thoracic, and lumbar spine regions. A neuroradiologist provided truth definition of vertebral positions in CT and radiography. 3D-2D registration was performed using the CMA-ES optimizer with 4 gradient-based image similarity metrics: (1) gradient information (GI); (2) gradient correlation (GC); (3) a novel variant referred to as gradient orientation (GO); and (4) a second variant referred to as truncated gradient correlation (TGC). Registration accuracy was evaluated in terms of the projection distance error (PDE) of the vertebral levels. Results: Conventional similarity metrics were susceptible to gross registration error and failure modes associated with the presence of surgical instrumentation: for GI, the median PDE and interquartile range was 33.0±43.6 mm; similarly for GC, PDE = 23.0±92.6 mm respectively. The robust metrics GO and TGC, on the other hand, demonstrated major improvement in PDE (7.6 ±9.4 mm and 8.1± 18.1 mm, respectively) and elimination of gross failure modes. Conclusion: The proposed GO and TGC similarity measures improve registration accuracy and robustness to gross failure in the presence of strong image content mismatch. Such

    The use of prophylactic antibiotics in orthopaedic surgery has been proven effective in reducing surgical site infections after hip and knee arthroplasty, spine procedures, and open reduction and internal fixation of fractures. To maximize the beneficial effect of prophylactic antibiotics, while minimizing any adverse effects, the correct antimicrobial agent must be selected, the drug must be administered just before incision, and the duration of administration should not exceed 24 hours.

    OBJECTIVE Quality and outcomes registry platforms lie at the center of many emerging evidence-driven reform models. Specifically, clinical registry data are progressively informing health care decision-making. In this analysis, the authors used data from a national prospective outcomes registry (the Quality Outcomes Database) to develop a predictive model for 12-month postoperative pain, disability, and quality of life (QOL) in patients undergoing elective lumbar spine surgery. METHODS Included in this analysis were 7618 patients who had completed 12 months of follow-up. The authors prospectively assessed baseline and 12-month patient-reported outcomes (PROs) via telephone interviews. The PROs assessed were those ascertained using the Oswestry Disability Index (ODI), EQ-5D, and numeric rating scale (NRS) for back pain (BP) and leg pain (LP). Variables analyzed for the predictive model included age, gender, body mass index, race, education level, history of prior surgery, smoking status, comorbid conditions, American Society of Anesthesiologists (ASA) score, symptom duration, indication for surgery, number of levels surgically treated, history of fusion surgery, surgical approach, receipt of workers' compensation, liability insurance, insurance status, and ambulatory ability. To create a predictive model, each 12-month PRO was treated as an ordinal dependent variable and a separate proportional-odds ordinal logistic regression model was fitted for each PRO. RESULTS There was a significant improvement in all PROs (p < 0.0001) at 12 months following lumbar spine surgery. The most important predictors of overall disability, QOL, and pain outcomes following lumbar spine surgery were employment status, baseline NRS-BP scores, psychological distress, baseline ODI scores, level of education, workers' compensation status, symptom duration, race, baseline NRS-LP scores, ASA score, age, predominant symptom, smoking status, and insurance status.

    Full Text Available Surgical site infections (SSIs after spinal surgery are a serious complication that can be minimized with prophylaxis. Vancomycin is a common agent used in the prevention of SSI. Given that vancomycin is renally cleared, its use requires careful observation in dialysis-dependent patients due to toxicity at supratherapeutic levels. Since minimum inhibitory concentrations (MICs for vancomycin have increased due to the emergence of resistant pathogens, the use of vancomycin in such patients is further complicated. Local instillation of vancomycin powder is thought to provide additional protection against SSI and have lower systemic absorption. We present a patient with end-stage renal disease that developed progressively debilitating cervical spondylotic myelopathy necessitating multilevel laminectomy and instrumented fusion. Prior to closure, 1 gram of vancomycin powder was sprinkled into the surgical incision. Postoperative serum vancomycin levels were well below those associated with nephrotoxicity and ototoxicity. Based on this experience, we reviewed the relevant guidelines that were designed to prevent postoperative infections in such dialysis-dependent patients. Intrawound application of vancomycin may be a legitimate and safe option for SSI prophylaxis in patients with renal failure on dialysis.

    Full Text Available Varicella-zoster virus and herpes simplex virus types 1 and 2 are neurotropic viruses that can be reactivated after a surgical or stressful intervention. Although such cases are uncommon, consequences can be debilitating, and variable treatment responses merit consideration. We describe a 41-year-old male with a history of varicella-mediated skin eruptions, who presented with continuing right arm pain, burning, and numbness in a C6 dermatomal distribution following a C5-6 anterior cervical discectomy and fusion and epidural steroid injections. The operative course was uncomplicated and he was discharged home on postoperative day 1. Approximately ten days after surgery, the patient presented to the emergency department complaining of severe pain in his right upper extremity and a vesicular rash from his elbow to his second digit. He was started on Acyclovir and discharged home. On outpatient follow-up, his rash had resolved though his pain continued. The patient was started on a neuromodulating agent for chronic pain. This case adds to the limited literature regarding this rare complication, brings attention to the symptoms for proper diagnosis and treatment, and emphasizes the importance of prompt antiviral therapy. We suggest adding a neuromodulating agent to prevent long-term sequelae and resolve acute symptoms.

    2012-09-01

    Full Text Available Abstract Background To report to the orthopedic community a case of vertebral fracture and adjacent vertebral subluxation through the upper instrumented vertebra after thoracolumbar fusion with augmentation of the cranial level. Methods This report reviewed the patient`s medical record, her imaging studies and related literature. The possible factors contributing to this fracture are hypothesized. Results A 70-year-old woman underwent decompressive surgery and posterolateral fusion for adult lumbar scoliosis. We used pedicular screws from T10 to S1 and iliac screw at the right side, augmented with cement at T10, T11, L1, L5 and S1; and prophylactic vertebroplasty at T9 to avoid the "topping-off syndrome". Thirty days after discharge, without recognizable inciting trauma, the patient complained of pain in the lower thoracic area. The exam revealed overall neurological deficit below the level of fracture. CT scan and MRI demonstrated a T10 vertebral collapse and T9 vertebral subluxation with morphologic features of flexion-distraction fracture through the upper edge of the screw. At this point, the authors performed posterior decompression at T9 to T10 and extended posterolateral arthrodesis from T2 to T10. To our knowledge, this is an unreported fracture. Conclusions Augmentation of the cranial level in a long thoracolumbar fusion has been developed to avoid the junctional kyphosis and compression fractures at that level. We alert the orthopedic community that this augmentation may lead to further and more severe fractures, although this opinion requires investigation for confirmation.

    Purpose: A flat-panel detector based mobile isocentric C-arm for cone-beam CT (CBCT) has been developed to allow intraoperative 3D imaging with sub-millimeter spatial resolution and soft-tissue visibility. Image quality and radiation dose were evaluated in spinal surgery, commonly relying on lower-performance image intensifier based mobile C-arms. Scan protocols were developed for task-specific imaging at minimum dose, in-room exposure was evaluated, and integration of the imaging system with a surgical guidance system was demonstrated in preclinical studies of minimally invasive spine surgery. Methods: Radiation dose was assessed as a function of kilovolt (peak) (80-120 kVp) and milliampere second using thoracic and lumbar spine dosimetry phantoms. In-room radiation exposure was measured throughout the operating room for various CBCT scan protocols. Image quality was assessed using tissue-equivalent inserts in chest and abdomen phantoms to evaluate bone and soft-tissue contrast-to-noise ratio as a function of dose, and task-specific protocols (i.e., visualization of bone or soft-tissues) were defined. Results were applied in preclinical studies using a cadaveric torso simulating minimally invasive, transpedicular surgery. Results: Task-specific CBCT protocols identified include: thoracic bone visualization (100 kVp; 60 mAs; 1.8 mGy); lumbar bone visualization (100 kVp; 130 mAs; 3.2 mGy); thoracic soft-tissue visualization (100 kVp; 230 mAs; 4.3 mGy); and lumbar soft-tissue visualization (120 kVp; 460 mAs; 10.6 mGy) - each at (0.3 x 0.3 x 0.9 mm{sup 3}) voxel size. Alternative lower-dose, lower-resolution soft-tissue visualization protocols were identified (100 kVp; 230 mAs; 5.1 mGy) for the lumbar region at (0.3 x 0.3 x 1.5 mm{sup 3}) voxel size. Half-scan orbit of the C-arm (x-ray tube traversing under the table) was dosimetrically advantageous (prepatient attenuation) with a nonuniform dose distribution ({approx}2 x higher at the entrance side than at isocenter

    2015-01-01

    Full Text Available Introduction. Plastic surgery is a medical specialty dealing with corrections of defects, improvements in appearance and restoration of lost function. Ancient Times. The first recorded account of reconstructive plastic surgery was found in ancient Indian Sanskrit texts, which described reconstructive surgeries of the nose and ears. In ancient Greece and Rome, many medicine men performed simple plastic cosmetic surgeries to repair damaged parts of the body caused by war mutilation, punishment or humiliation. In the Middle Ages, the development of all medical braches, including plastic surgery was hindered. New age. The interest in surgical reconstruction of mutilated body parts was renewed in the XVIII century by a great number of enthusiastic and charismatic surgeons, who mastered surgical disciplines and became true artists that created new forms. Modern Era. In the XX century, plastic surgery developed as a modern branch in medicine including many types of reconstructive surgery, hand, head and neck surgery, microsurgery and replantation, treatment of burns and their sequelae, and esthetic surgery. Contemporary and future plastic surgery will continue to evolve and improve with regenerative medicine and tissue engineering resulting in a lot of benefits to be gained by patients in reconstruction after body trauma, oncology amputation, and for congenital disfigurement and dysfunction.

    (400 N) was applied and then the hybrid loading condition was applied to measure the ROM and COR in the sagittal plane. The more the nonlinearity was included in the model the closer the motion behavior of the device was to that of the intact spine. Furthermore, our results showed that the nonlinearity of the semi-rigid rod was a more sensitive factor than the nonlinearity of the spinal ligaments on biomechanical behavior of the lumbar spine after surgery. Therefore, for better understanding of the surgical effectiveness of the spinal device, more realistic material properties such as nonlinearity of the device and anatomic elements should be considered. In particular, the nonlinear properties of the semi-rigid rod were considered more than the nonlinearity of spinal ligaments.

    In image-guided spine surgery, robust three-dimensional to two-dimensional (3D-2D) registration of preoperative computed tomography (CT) and intraoperative radiographs can be challenged by the image content mismatch associated with the presence of surgical instrumentation and implants as well as soft-tissue resection or deformation. This work investigates image similarity metrics in 3D-2D registration offering improved robustness against mismatch, thereby improving performance and reducing or eliminating the need for manual masking. The performance of four gradient-based image similarity metrics (gradient information (GI), gradient correlation (GC), gradient information with linear scaling (GS), and gradient orientation (GO)) with a multi-start optimization strategy was evaluated in an institutional review board-approved retrospective clinical study using 51 preoperative CT images and 115 intraoperative mobile radiographs. Registrations were tested with and without polygonal masks as a function of the number of multistarts employed during optimization. Registration accuracy was evaluated in terms of the projection distance error (PDE) and assessment of failure modes (PDE  >  30 mm) that could impede reliable vertebral level localization. With manual polygonal masking and 200 multistarts, the GC and GO metrics exhibited robust performance with 0% gross failures and median PDE  registration to fail at a rate of  >14% however, GO maintained robustness with a 0% gross failure rate. Overall, the GI, GC, and GS metrics were susceptible to registration errors associated with content mismatch, but GO provided robust registration (median PDE  =  5.5 mm, 2.6 mm IQR) without manual masking and with an improved runtime (29.3 s). The GO metric improved the registration accuracy and robustness in the presence of strong image content mismatch. This capability could offer valuable assistance and decision support in spine level localization in a

    Vertical growth of the cervical spine, of the mandibula and the upper maxilla are normally anatomically and physiologically correlated. At a very early age the relationships are established between the cervical spine and the angle of the mandibula which is normally level with C2's antero-inferior angle. A parallelism can be noticed between the rhythms of the vertical growth of the cervical spine and the changes of the maxillary in relation to the skull. So relationships are gradually established between the palate level, the top of the odontoid, and the foramen magnum. These relationships are well objectivized on a lateral teleradiography by Delaire' analysis. Lateral teleradiography of the situation of the angle of the mandibula, in relation to the basis of the C2 body should be systematic. It provides much information concerning the growth potential of the condylar unit, and makes possible a differential diagnosis between true or false posterior vertical insufficiency (PVI) and true or false posterior vertical excess (PVE) and to recognize clinical types of skeletal class II and class III of vertical origin.

    Background: Scoliosis surgery has undergone a dramatic evolution over the past 20 years with the advent of new surgical techniques and sophisticated instrumentation. Surgeons have realized scoliosis is a complex multiplanar deformity that requires thorough knowledge of spinal anatomy and pathophysiology in order to manage patients afflicted by it. Nonoperative modalities such as bracing and casting still play roles in the treatment of scoliosis; however, it is the operative treatment that has revolutionized the treatment of this deformity that affects millions worldwide. As part of the evolution of scoliosis surgery, newer implants have resulted in improved outcomes with respect to deformity correction, reliability of fixation, and paucity of complications. Each technique and implant has its own set of unique complications, and the surgeon must appreciate these when planning surgery. Materials and methods: Various surgical techniques and types of instrumentation typically used in scoliosis surgery are briefly discussed. Though scoliosis surgery is associated with a wide variety of complications, only those that directly involve the hardware are discussed. The current literature is reviewed and several illustrative cases of patients treated for scoliosis at the Connecticut Children's Medical Center and the Newington Children's Hospital in Connecticut are briefly presented. Conclusion: Spine surgeons and radiologists should be familiar with the different types of instrumentation in the treatment of scoliosis. Furthermore, they should recognize the clinical and roentgenographic signs of hardware failure as part of prompt and effective treatment of such complications. (orig.)

    Musculoskeletal surgery is associated with a high risk of venous thrombosis and pulmonary embolism. The introduction of direct oral anticoagulants (DOAK) has broadened the possibilities for prevention of venous thromboembolism in the course of orthopedic and trauma surgery. Addressing this recent development, the Austrian Societies of Orthopedics and Orthopedic Surgery (ÖGO), Trauma Surgery (ÖGU), Hematology and Oncology (OeGHO) and of Anaesthesiology, Reanimation und Intensive Care Medicine (ÖGARI) have taken the initiative to create Austrian guidelines for the prevention of thromboembolism after total hip and knee replacement, hip fracture surgery, interventions at the spine and cases of minor orthopedic and traumatic surgery. Furthermore, the pharmacology of the DOAK and the pivotal trial data for each of the three currently available substances - apixaban, dabigatran, and rivaroxaban - are briefly presented. Separate chapters are dedicated to "anticoagulation and neuroaxial anesthesia" and "bridging".

    Surgery of Crohns disease is an important part of the general treatment algorithm. The role of surgery is changing with the development of conservative procedures. The recent years have seen the return to early treatment of patients with Crohns disease. Given the character of the disease and its intestinal symptoms, a specific approach to these patients is necessary, especially regarding the correct choice of surgery. The paper focuses on the luminal damage of the small and large intestine including complications of the disease. We describe the individual indications for a surgical solution, including the choice of anastomosis or multiple / repeated surgeries.

    2007-04-01

    Bariatric surgery as a means to treat obesity is becoming increasingly common in the United States. An early form of bariatric surgery, the jejunoileal bypass, had to be abandoned in 1980 due to numerous complications, including hyperoxaluria and kidney stones. Current bariatric procedures have not been systematically evaluated to determine if they cause hyperoxaluria. Presented here are data showing that hyperoxaluria is the major metabolic abnormality in patients with bariatric surgery who form kidney stones. Further studies are needed to assess the prevalence of hyperoxaluria in all patients with bariatric surgery.

    Surgery centers have been accepted as a cost effective, patient friendly vehicle for delivery of quality ambulatory care. Hospitals and physician groups also have made them the vehicles for coming together. Surgery centers allow hospitals and physicians to align incentives and share benefits. It is one of the few types of health care businesses physicians can own without anti-fraud and abuse violation. As a result, many surgery center ventures are now jointly owned by hospitals and physician groups. This article outlines common structures that have been used successfully to allow both to own and govern surgery centers.

    Haemorrhage after thyroid surgery is rare, but if it occurs it is a life-threatening condition necessitating emergency surgery. The aim of this study was to evaluate prevalence and risk factors of haemorrhage after thyroid surgery. A retrospective analysis was undertaken in a group of 8931 consecutive patients with various thyroid diseases treated in 2004-2013 at our institution. Potential risk factors for postoperative haemorrhage after thyroid surgery were analysed using logistic regression model. Haemorrhage after thyroid operation necessitating emergency surgery occurred in 40 (0.45%) of 8931 patients. None of the patients died within the perioperative period. Bleeding occurred within first 24 hours following surgery in 38 (95%) patients, and in the remaining 2 (5%) patients in more than 24 hours after initial surgery. The following risk factors for bleeding after thyroid operation were identified: male sex (OR 3.618; 1.762-7.430; p or = 70 years (OR 3.052; 1.275-7.304; p = 0.012), surgery for hyperthyroidism (OR 2.873; 1.511-5.462; p = 0.001), smoking (OR 2.855; 1.502-5.428; p = 0.001), subtotal thyroidectomy in contrast to total thyroidectomy or lobectomy (OR 2.853; 1.356-6.004; p=0.006), and thyroid operation undertaken by resident in training in general surgery (OR 2.596; 1.393-4.837; p = 0.003). Haemorrhage after thyroid operation necessitating emergency surgical intervention occurs most frequently within first 24 hour following surgery. Hence, for safety reasons a minimum of 24-hour hospital stay is recommended in all patients with risk factors for postoperative bleeding after thyroid operation. Quality monitoring of thyroid surgery should include also risk factors for postoperative bleeding.

    Posterior reversible encephalopathy syndrome (PRES) usually manifests with severe headaches, seizures, and visual disturbances due to uncontrollable hypertension. A patient (age in the early 60s) with a history of renal cell cancer presented with lower-extremity weakness and paresthesias. Magnetic resonance imaging (MRI) of the thoracic spine revealed a T8 vertebral body metastatic lesion with cord compression at that level. The patient underwent preoperative embolization of the tumor followed by posterior resection and placement of percutaneous pedicle screws and rods. Postoperatively, the patient experienced decreased visual acuity bilaterally. Abnormal MRI findings consisted of T2 hyperintense lesions and fluid-attenuated inversion recovery changes in both occipital lobes, consistent with the unique brain imaging pattern associated with PRES. The patient’s blood pressure was normal and stable from the first day of hospitalization. The patient was kept on high-dose steroid therapy, which was started intraoperatively, and improved within 48 hours after symptom onset. PMID:26858804

  10. Best evidence in multimodal pain management in spine surgery and means of assessing postoperative pain and functional outcomes.

    2015-06-01

    Multimodal approaches to pain management have arisen with the goal of improving postoperative pain and reducing opioid analgesic use. We performed a comprehensive literature review to determine grades of recommendation for commonly used agents in multimodal pain management and provide a best practice guideline. To evaluate common drugs used in multimodal treatment of pain, a search was performed on English language publications on Medline (PubMed; National Library of Medicine, Bethesda, MD, USA). Manuscripts were rated as Level I-V according to the North American Spine Society's (NASS) standardized levels of evidence tables. Grades of recommendation were assigned for each drug based on the NASS Clinical Guidelines for Multidisciplinary Spine Care. There is good (Grade A) evidence gabapentinoids, acetaminophen, neuraxial blockade and extended-release local anesthetics reduce postoperative pain and narcotic requirements. There is fair (Grade B) evidence that preemptive analgesia and nonsteroidal anti-inflammatory drugs (NSAID) result in reduced postoperative pain. There is insufficient and/or conflicting (Grade I) evidence that muscle relaxants and ketamine provide a significant reduction in postoperative pain or narcotic usage. There is fair (Grade B) evidence that short-term use of NSAID result in no long-term reduction in bone healing or fusion rates. Comprehensive assessment of the effectiveness of perioperative pain control can be accomplished through the use of validated measures. Multimodal pain management protocols have consistently been demonstrated to allow for improved pain control with less reliance on opioids. There is good quality evidence that supports many of the common agents utilized in multimodal therapy, however, there is a lack of evidence regarding optimal postoperative protocols or pathways.

    Minimally invasive surgery has revolutionized gynecological interventions over the past 30 years. The introduction of the da Vinci robotic surgery in 2005 has resulted in large changes in surgical management. The robotic platform allows less experienced laparoscopic surgeons to perform more complex procedures. It can be utilized mainly in general gynecology and reproductive gynecology. The robot is being increasingly used for procedures such as hysterectomy, myomectomy, adnexal surgery, and tubal anastomosis. In urogynecology, the robot is being utilized for sacrocolopexy as well. In the field of gynecologic oncology, the robot is being increasingly used for hysterectomy and lymphadenectomy in oncologic diseases. Despite the rapid and widespread adaption of robotic surgery in gynecology, there are no randomized trials comparing its efficacy and safety to other traditional surgical approaches. This article presents the development, technical aspects and indications of robotic surgery in gynecology, based on the previously published reviews. Robotic surgery can be highly advantageous with the right amount of training, along with appropriate patient selection. Patients will have less blood loss, less post-operative pain, faster recovery, and fewer complications compared to open surgery and laparoscopy. However, until larger randomized control trials are completed which report long-term outcomes, robotic surgery cannot be stated to have priority over other surgical methods.

    A 3D-2D image registration method is presented that exploits knowledge of interventional devices (e.g. K-wires or spine screws—referred to as ‘known components’) to extend the functionality of intraoperative radiography/fluoroscopy by providing quantitative measurement and quality assurance (QA) of the surgical product. The known-component registration (KC-Reg) algorithm uses robust 3D-2D registration combined with 3D component models of surgical devices known to be present in intraoperative 2D radiographs. Component models were investigated that vary in fidelity from simple parametric models (e.g. approximation of a screw as a simple cylinder, referred to as ‘parametrically-known’ component [pKC] registration) to precise models based on device-specific CAD drawings (referred to as ‘exactly-known’ component [eKC] registration). 3D-2D registration from three intraoperative radiographs was solved using the covariance matrix adaptation evolution strategy (CMA-ES) to maximize image-gradient similarity, relating device placement relative to 3D preoperative CT of the patient. Spine phantom and cadaver studies were conducted to evaluate registration accuracy and demonstrate QA of the surgical product by verification of the type of devices delivered and conformance within the ‘acceptance window’ of the spinal pedicle. Pedicle screws were successfully registered to radiographs acquired from a mobile C-arm, providing TRE 1-4 mm and  registration. Using advanced pKC models, screws that did not match the device models specified in the surgical plan were detected with an accuracy of  >99%. Visualization of registered devices relative to surgical planning and the pedicle acceptance window provided potentially valuable QA of the surgical product and reliable detection of pedicle screw breach. 3D-2D registration combined with 3D models of known surgical devices offers a novel method for intraoperative QA. The method provides a near-real-time independent

    2015-01-01

    Cost effectiveness has been demonstrated for traditional lumbar discectomy, lumbar laminectomy as well as for instrumented and noninstrumented arthrodesis. While emerging evidence suggests that minimally invasive spine surgery reduces morbidity, duration of hospitalization, and accelerates return to activites of daily living, data regarding cost effectiveness of these novel techniques is limited. The current study analyzes all available data on minimally invasive techniques for lumbar discectomy, decompression, short-segment fusion and deformity surgery. In general, minimally invasive spine procedures appear to hold promise in quicker patient recovery times and earlier return to work. Thus, minimally invasive lumbar spine surgery appears to have the potential to be a cost-effective intervention. Moreover, novel less invasive procedures are less destabilizing and may therefore be utilized in certain indications that traditionally required arthrodesis procedures. However, there is a lack of studies analyzing the economic impact of minimally invasive spine surgery. Future studies are necessary to confirm the durability and further define indications for minimally invasive lumbar spine procedures. PMID:25793159

    Deltoid muscle weakness due to C-5 nerve root injury following cervical spine surgery is an uncommon but potentially debilitating complication. Symptoms can manifest upon emergence from anesthesia or days to weeks following surgery. There is conflicting evidence regarding the efficacy of spontaneous electromyography (spEMG) monitoring in detecting evolving C-5 nerve root compromise. By contrast, transcranial electrical stimulation-induced motor evoked potential (tceMEP) monitoring has been shown to be highly sensitive and specific in identifying impending C-5 injury. In this study the authors sought to 1) determine the frequency of immediate versus delayed-onset C-5 nerve root injury following cervical spine surgery, 2) identify risk factors associated with the development of C-5 palsies, and 3) determine whether tceMEP and spEMG neuromonitoring can help to identify acutely evolving C-5 injury as well as predict delayed-onset deltoid muscle paresis. The authors retrospectively reviewed the neuromonitoring and surgical records of all patients who had undergone cervical spine surgery involving the C-4 and/or C-5 level in the period from 2006 to 2008. Real-time tceMEP and spEMG monitoring from the deltoid muscle was performed as part of a multimodal neuromonitoring protocol during all surgeries. Charts were reviewed to identify patients who had experienced significant changes in tceMEPs and/or episodes of neurotonic spEMG activity during surgery, as well as those who had shown new-onset deltoid weakness either immediately upon emergence from the anesthesia or in a delayed fashion. Two hundred twenty-nine patients undergoing 235 cervical spine surgeries involving the C4-5 level served as the study cohort. The overall incidence of perioperative C-5 nerve root injury was 5.1%. The incidence was greatest (50%) in cases with dual corpectomies at the C-4 and C-5 spinal levels. All patients who emerged from anesthesia with deltoid weakness had significant and unresolved

    National Health Service (NHS) statistics in the United Kingdom demonstrate an increase in clinical negligence claims over the past 30 years. Reasons for this include elements of a cultural shift in attitudes toward the medical profession and the growth of the legal services industry. This issue affects medical and surgical health providers worldwide.The authors analyzed 2117 NHS Litigation Authority (NHSLA) orthopedic surgery claims between 1995 and 2001 with respect to these clinical areas: emergency department, outpatient care, surgery (elective or trauma operations), and inpatient care. The authors focused on the costs of settling and defending claims, costs attributable to clinical areas, common causes of claims, and claims relating to elective or trauma surgery. Numbers of claims and legal costs increased most notably in surgery (elective and trauma) and in the emergency department. However, claims are being defended more robustly. The annual cost for a successful defense has remained relatively stable, showing a slight decline. The common causes of claims are postoperative complication; wrong, delayed, or failure of diagnosis; inadequate consent; and wrong-site surgery. Certain surgical specialties (eg, spine and lower-limb surgery) have the most claims made during elective surgery, whereas upper-limb surgery has the most claims made during trauma surgery.The authors recommend that individual trusts liaise with orthopedic surgeons to devise strategies to address areas highlighted in our study. Despite differences in health care systems worldwide, the underlying issues are common. With improved understanding, physicians can deliver the service they promise their patients.

    Physical therapy and orthopedic surgery are important components in the treatment of ankylosing spondylitis (AS). Supervised physical therapy is more effective that individual or unsupervised exercise in improving symptoms, but controlled trials suggest than combined inpatient and outpatient therapy provides the greatest improvement. Recommendations for exercise are universal, but the best types and sequence of therapies are not known. Total hip replacement is the surgery most commonly performed for AS, with good long-term implant survival. Heterotopic ossification may occur no more frequently after hip replacement in patients with AS than in patients with other diseases. Corrective spinal surgery is rarely performed and requires specialized centers and experienced surgeons. PMID:22543536

    2014-04-01

    Trephination of the equine sinuses is a common surgical procedure in sedated standing horses. Standing sinus flap surgery has become increasingly popular in equine referral hospitals and offers several advantages over sinusotomy performed under general anesthesia, including reduced patient-associated risks and costs; less intraoperative hemorrhage, allowing better visualization of the operative site; and allows surgeons to take their time. Other minimally invasive surgical procedures include sinoscopic surgery, balloon sinuplasty, and transnasal laser sinonasal fenestration. Despite the procedure used, appropriate indications for surgery, good patient selection, and familiarity with regional anatomy and surgical techniques are imperative for good results.

    Donald A. Ross

    2014-01-01

    Full Text Available The object of the study was to review the author’s large series of minimally invasive spine surgeries for complication rates. The author reviewed a personal operative database for minimally access spine surgeries done through nonexpandable tubular retractors for extradural, nonfusion procedures. Consecutive cases (n=1231 were reviewed for complications. There were no wound infections. Durotomy occurred in 33 cases (2.7% overall or 3.4% of lumbar cases. There were no external or symptomatic internal cerebrospinal fluid leaks or pseudomeningoceles requiring additional treatment. The only motor injuries were 3 C5 root palsies, 2 of which resolved. Minimally invasive spine surgery performed through tubular retractors can result in a low wound infection rate when compared to open surgery. Durotomy is no more common than open procedures and does not often result in the need for secondary procedures. New neurologic deficits are uncommon, with most observed at the C5 root. Minimally invasive spine surgery, even without benefits such as less pain or shorter hospital stays, can result in considerably lower complication rates than open surgery.

    2016-12-01

    Neonatal surgery is recognized as an independent discipline in general surgery, requiring the expertise of pediatric surgeons to optimize outcomes in infants with surgical conditions. Survival following neonatal surgery has improved dramatically in the past 60 years. Improvements in pediatric surgical outcomes are in part attributable to improved understanding of neonatal physiology, specialized pediatric anesthesia, neonatal critical care including sophisticated cardiopulmonary support, utilization of parenteral nutrition and adjustments in fluid management, refinement of surgical technique, and advances in surgical technology including minimally invasive options. Nevertheless, short and long-term complications following neonatal surgery continue to have profound and sometimes lasting effects on individual patients, families, and society.

    Full Text Available Cosmetic surgery is one of the two branches of plastic surgery. The characteristic of non-necessity of this surgical speciality implies an increased severity in the evaluation of the risk-benefit balance. Therefore, great care must be taken in providing all the information necessary in order to obtain valid consent to the intervention. We analyzed judgments concerning cosmetic surgery found in national legal databases. A document of National Bioethics Committee (CNB was also analyzed. Conclusion: The receipt of valid, informed consent is of absolute importance not only to legitimise the medical-surgical act, but it also represents the key element in the question concerning the existence of an obligation to achieve certain results/use of certain methods in the cosmetic surgery.

    Over the past few decades, robotic surgery has developed from a futuristic dream to a real, widely used technology. Today, robotic platforms are used for a range of procedures and have added a new facet to the development and implementation of minimally invasive surgeries. The potential advantages are enormous, but the current progress is impeded by high costs and limited technology. However, recent advances in haptic feedback systems and single-port surgical techniques demonstrate a clear role for robotics and are likely to improve surgical outcomes. Although robotic surgeries have become the gold standard for a number of procedures, the research in colorectal surgery is not definitive and more work needs to be done to prove its safety and efficacy to both surgeons and patients.

    Changes in cosmetic surgery will be driven by several key forces. The patient's self-image, and perceived place in society, will continue to drive patients to the cosmetic surgeon as well as to demand newer and better treatments. Technological advances, especially those based on an enhanced understanding of cellular and tissue physiology, promise enhanced tools other than the scalpel for the surgeon. Conceptual advances in our understanding of beauty and patient psychology will lead to a more integrative approach to cosmetic surgery.

    Objective To investigate the effect of parecoxib sodium on vein analgesia after orthopaedic lumbar spine surgery. Methods 60 cases underwent selective orthopaedic lumbar spine surgery under general anesthesia were randomly divided equally into two groups. Group A received intravenous parecoxib sodium 40 mg,and group B received intravenous NS 2 mL instead of parecoxib sodium at 30 min before the end of operation. All the patients received PCIA immediately after surgery. Pain intensity was measured by visual analog scale( VAS )score at the time of awaking and 2 ,4 ,8 ,24 ,48 h after operation. The total consumption of sufentanil, the valid number of pressing PCA pump were recorded at 24,48 h after operation. Meanwhile, the score of Ramsay sedation scale and the adverse effects were observed after operation. Results There were significant differences in the VAS score, valid number of pressing PCA pump and sufentanil consumption between the two groups( P 0.05),镇痛期间各种不良反应发生率比较差异无统计学意义(P>0.05).结论 静脉注射帕瑞昔布钠40 mg用于腰椎内固定手术术后镇痛可以增强舒芬太尼PCA镇痛效果.

    Full Text Available Kathleen T Berg, Andrew R Harrison, Michael S LeeDepartment of Ophthalmology, University of Minnesota, Minneapolis, MN, USAAbstract: Incidence estimates for perioperative vision loss (POVL after nonocular surgery range from 0.013% for all surgeries up to 0.2% following spine surgery. The most common neuro-ophthalmologic causes of POVL are the ischemic optic neuropathies (ION, either anterior (AION or posterior (PION. We identified 111 case reports of AION following nonocular surgery in the literature, with most occurring after cardiac surgery, and 165 case reports of PION following nonocular surgery, with most occurring after spine surgery or radical neck dissection. There were an additional 526 cases of ION that did not specify if the diagnosis was AION or PION. We also identified 933 case reports of central retinal artery occlusion (CRAO, 33 cases of pituitary apoplexy, and 245 cases of cortical blindness following nonocular surgery. The incidence of POVL following ocular surgery appears to be much lower than that seen following nonocular surgery. We identified five cases in the literature of direct optic nerve trauma, 47 cases of AION, and five cases of PION following ocular surgery. The specific pathogenesis and risk factors underlying these neuro-ophthalmic complications remain unknown, and physicians should be alert to the potential for loss of vision in the postoperative period.Keywords: perioperative, postoperative, vision loss, ocular surgery, nonocular surgery

    2014-01-01

    The impact of bariatric surgery beyond its effect on weight loss has entailed a change in the way of regarding it. The term metabolic surgery has become more popular to designate those interventions that aim at resolving diseases that have been traditionally considered as of exclusive medical management, such as type 2 diabetes mellitus (T2D). Recommendations for metabolic surgery have been largely addressed and discussed in worldwide meetings, but no definitive consensus has been reached yet. Rates of diabetes remission after metabolic surgery have been one of the most debated hot topics, with heterogeneity being a current concern. This review aims to identify and clarify controversies regarding metabolic surgery, by focusing on a critical analysis of T2D remission rates achieved with different bariatric procedures, and using different criteria for its definition. Indications for metabolic surgery for patients with T2D who are not morbidly obese are also discussed. Copyright © 2013 SEEN. Published by Elsevier Espana. All rights reserved.

    Full Text Available Approximately 60% of all patients with epilepsy suffer from focal epilepsy syndromes. In about 15% of these patients, the seizures are not adequately controlled with antiepileptic drugs; such patients are potential candidates for surgical treatment and the major proportion is in the pediatric group (18 years old or less. Epilepsy surgery in children who have been carefully chosen can result in either seizure freedom or a marked (>90% reduction in seizures in approximately two-thirds of children with intractable seizures. Advances in structural and functional neuroimaging, neurosurgery, and neuroanaesthesia have improved the outcomes of surgery for children with intractable epilepsy. Early surgery improves the quality of life and cognitive and developmental outcome and allows the child to lead a normal life. Surgically remediable epilepsies should be identified early and include temporal lobe epilepsy with hippocampal sclerosis, lesional temporal and extratemporal epilepsy, hemispherical epilepsy, and gelastic epilepsy with hypothalamic hamartoma. These syndromes have both acquired and congenital etiologies and can be treated by resective or disconnective surgery. Palliative procedures are performed in children with diffuse and multifocal epilepsies who are not candidates for resective surgery. The palliative procedures include corpus callosotomy and vagal nerve stimulation while deep brain stimulation in epilepsy is still under evaluation. For children with "surgically remediable epilepsy," surgery should be offered as a procedure of choice rather than as a treatment of last resort.

    Full Text Available FDA approved Da Vinci Surgical System in 2005 for gynecological surgery. It has been rapidly adopted and it has already assumed an important position at various centers where this is available. It comprises of three components: A surgeon′s console, a patient-side cart with four robotic arms and a high-definition three-dimensional (3D vision system. In this review we have discussed various robotic-assisted laparoscopic benign gynecological procedures like myomectomy, hysterectomy, endometriosis, tubal anastomosis and sacrocolpopexy. A PubMed search was done and relevant published studies were reviewed. Surgeries that can have future applications are also mentioned. At present most studies do not give significant advantage over conventional laparoscopic surgery in benign gynecological disease. However robotics do give an edge in more complex surgeries. The conversion rate to open surgery is lesser with robotic assistance when compared to laparoscopy. For myomectomy surgery, Endo wrist movement of robotic instrument allows better and precise suturing than conventional straight stick laparoscopy. The robotic platform is a logical step forward to laparoscopy and if cost considerations are addressed may become popular among gynecological surgeons world over.

    Laser surgery provides good exposure with clear operating fields and satisfactory preliminary functional results. In contrast to conventional excision, it was found that matrix metalloproteinases and the tissue inhibitors of metalloproteinases -1 mRNA expression is higher, myofibroblasts appeared and disappeared slower in laser excision wounds. It has been suggested that the better anatomical and functional results achieved following laser cordectomy may be explained by the fact that such procedures result in better, more rapid healing processes to recover vocal cord for early glottic tumors and better. In this paper, the role of photobiomodulation in laser surgery will be discussed by the cultured monolayer normal human skin fibroblast model of the photobiomodulation of marginal irradiation of high intensity laser beam, the photobiomodulation related to the irradiated tissue, the biological information model of photobiomodulation and the animal models of laser surgery. Although high intensity laser beam is so intense that it destroys the irradiated cells or tissue, its marginal irradiation intensity is so low that there is photobiomodulation on non-damage cells to modulate the regeneration of partly damaged tissue so that the surgery of laser of different parameters results in different post-surgical recovery. It was concluded that photobiomodulation might play an important role in the long-term effects of laser surgery, which might be used to design laser surgery.

    In the past few years, stem cells have become the focusof research by regenerative medicine professionals andtissue engineers. Embryonic stem cells, although capableof differentiating into cell lineages of all three germlayers, are limited in their utilization due to ethical issues.In contrast, the autologous harvest and subsequenttransplantation of adult stem cells from bone marrow,adipose tissue or blood have been experimentally utilizedin the treatment of a wide variety of diseases rangingfrom myocardial infarction to Alzheimer's disease. Thephysiologic consequences of stem cell transplantationand its impact on functional recovery have been studiedin countless animal models and select clinical trials.Unfortunately, the bench to bedside translation of thisresearch has been slow. Nonetheless, stem cell therapyhas received the attention of spinal surgeons due to itspotential benefits in the treatment of neural damage,muscle trauma, disk degeneration and its potentialcontribution to bone fusion.

    2017-01-01

    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.

    With the improvement of the instrument and development of the technique, the same curative effects can be achieved in modern percutaneous endoscopic spine surgery as in traditional open surgery in the treatment of lumbar disc herniation. And the occurrence rate of complications is obviously reduced. The percutaneous endoscopic technique can be performed via the interlaminar approach and the transforaminal approach. Lumbar spinal stenosis and joint bone cyst are effectively treated with percutaneous endoscopic spinal canal decompression. Good curative results will be obtained in percutaneous endoscopic cervical discectomy and cervical intervertebral foramen dissection via anterior and posterior approaches for cervical disc herniation, cervical foraminal stenosis and so on. With unique advantages and higher treatment effectiveness, the percutaneous endoscopic technique is also effective in the treatment of chronic cervical and lumbar pain.

    2016-01-01

    Robotic surgery is the most dynamic development in the sector of minimally invasive operations currently. It should not be viewed as an alternative to laparoscopy, but as the next step in a process of technological evolution. The advancement of robotic surgery, in terms of the introduction of the Da Vinci Xi, permits the variable use of optical devices in all four trocars. Due to the new geometry of the "patient cart," an operation can be performed in all spatial directions without re-docking. Longer instruments and the markedly narrower mechanical elements of the "patient cart" provide greater flexibility as well as access similar to those of traditional laparoscopy. Currently, robotic surgery is used for a variety of indications in the treatment of benign gynecological diseases as well as malignant ones. Interdisciplinary cooperation and cooperation over large geographical distances have been rendered possible by telemedicine, and will ensure comprehensive patient care in the future by highly specialized surgery teams. In addition, the second operation console and the operation simulator constitute a new dimension in advanced surgical training. The disadvantages of robotic surgery remain the high costs of acquisition and maintenance as well as the laborious training of medical personnel before they are confident with using the technology.

    Surgery has consistently been demonstrated to be the most effective long-term therapy for the treatment of obesity. However, despite excellent outcomes with current procedures, most patients with obesity- and weight-related comorbidities who meet criteria for surgical treatment choose not to pursue surgery out of fear of operative risks and complications or concerns about high costs. Novel minimally invasive procedures and devices may offer alternative solutions for patients who are hesitant to pursue standard surgical approaches. These procedures may be used for primary treatment of obesity, early intervention for patients approaching morbid obesity, temporary management prior to bariatric surgery, or revision of bypass surgery associated with weight regain. Novel bariatric procedures can in general be divided into four categories: endoluminal space-occupying devices, gastric suturing and restrictive devices, absorption-limiting devices, and neural-hormonal modulating devices. Many of these are only approved as short-term interventions, but these devices may be effective for patients desiring low-risk procedures or a transient effect. We will see the expansion of indications and alternatives for metabolic surgery as these techniques gain approval.

    Percutaneous methods can be used to perform many surgical procedures on the soft tissues and bones of the forefoot, thereby providing treatment options for all the disorders and deformities seen at this site. Theoretical advantages of percutaneous surgery include lower morbidity rates and faster recovery with immediate weight bearing. Disadvantages are the requirement for specific equipment, specific requirements for post-operative management, and lengthy learning curve. At present, percutaneous hallux valgus correction is mainly achieved with chevron osteotomy of the first metatarsal, for which internal fixation and a minimally invasive approach (2 cm incision) seem reliable and reproducible. This procedure is currently the focus of research and evaluation. Percutaneous surgery for hallux rigidus is simple and provides similar outcomes to those of open surgery. Lateral metatarsal malalignment and toe deformities are good indications for percutaneous treatment, which produces results similar to those of conventional surgery with lower morbidity rates. Finally, fifth ray abnormalities are currently the ideal indication for percutaneous surgery, given the simplicity of the procedure and post-operative course, high reliability, and very low rate of iatrogenic complications. The most commonly performed percutaneous techniques are described herein, with their current indications, main outcomes, and recent developments.

    For the year 2015, almost 19,000 published references can be found in PubMed when entering the search term "cardiac surgery". The last year has been again characterized by lively discussions in the fields where classic cardiac surgery and modern interventional techniques overlap. Lacking evidence in the field of coronary revascularization with either percutaneous coronary intervention or bypass surgery has been added. As in the years before, CABG remains the gold standard for the revascularization of complex stable triple-vessel disease. Plenty of new information has been presented comparing the conventional to transcatheter aortic valve implantation (TAVI) demonstrating similar short- and mid-term outcomes at high and low risk, but even a survival advantage with transfemoral TAVI at intermediate risk. In addition, there were many relevant and interesting other contributions from the purely operative arena. This review article will summarize the most pertinent publications in the fields of coronary revascularization, surgical treatment of valve disease, heart failure (i.e., transplantation and ventricular assist devices), and aortic surgery. While the article does not have the expectation of being complete and cannot be free of individual interpretation, it provides a condensed summary that is intended to give the reader "solid ground" for up-to-date decision-making in cardiac surgery.

    To analyze critically the effectiveness and value of bibliometric indicators in journals of Surgery or Cardiovacular Surgery in the context of the postgraduate programs of CAPES Medicine III. A sampling with 16 academic programs and one professional master of Medicine III, encompassing the General and Digestive System Surgery, Cardiovascular Surgery and Multidisciplinary courses with such contents, was evaluated. Thomson Reuters/ISI (JCR), Elsevier/Scopus (SJR), and also Scielo databases were used. Only in seven programs, the teachers had an average of Qualis A1 articles greater than the others strata. Eleven journals in the surgical area are in stratum A1 (5%) and it reaches 25% in Cardiovascular Surgery. Among the six journals with the largest number of publications Qualis A1 in area Medicine III, five are from non-specific areas. The Acta Cirúrgica Brasileira represented 58% of the publications in the stratum A2. There are some obstacles in the Qualis classification with little uniformity among the Medicine areas I, II and III. A permanent committee should be set to update the Qualis, composed by the three medical areas. It should be considered using other index databases and the unification of the Qualis criteria for journals in medicine. Rating criteria of multi and transdisciplinary journals need to be reviewed. It is essential an institutional financial support for national journals chosen by peers aiming to provide a full computerization process and a professional reviewer of the English language, in order to increase the impact factor.

    Morbid obesity is defined as obesity with body mass index (BMI) > or = 40 kg/m2 with secondary serious diseases. Conservative treatment generally fails to produce long-term weight loss in these patients, since several bariatric surgical techniques have been developed which are based on gastric restriction and/or gastric malabsorption resulting in permanent weight loss over years. Preoperative evaluation might detect suitable patients and reduce both non-surgical and surgical complications. Postoperative follow-up in a multidisciplinary program, including specialists in various fields of medicine, e.g. surgery, internal medicine, radiology, paediatrics and nutritional surveillance are mandatory in the treatment of patients after obesity surgery. Bariatric surgery results in a major weight loss, with amelioration of most obesity-associated conditions. The most serious side effect of some surgical procedere is malnutrition.

    Surgical robotics was first utilized to facilitate neurosurgical biopsies in 1985, and it has since found application in orthopedics, urology, gynecology, and cardiothoracic, general, and vascular surgery. Surgical assistance systems provide intelligent, versatile tools that augment the physician's ability to treat patients by eliminating hand tremor and enabling dexterous operation inside the patient's body. Surgical robotics systems have enabled surgeons to treat otherwise untreatable conditions while also reducing morbidity and error rates, shortening operative times, reducing radiation exposure, and improving overall workflow. These capabilities have begun to be realized in two important realms of aortic vascular surgery, namely, flexible robotics for exclusion of complex aortic aneurysms using branched endografts, and robot-assisted laparoscopic aortic surgery for occlusive and aneurysmal disease.

    Antimicrobial prophylaxis in surgery refers to a very brief course of an antimicrobial agent initiated just before the start of the procedure. The efficacy of antimicrobials to prevent postoperative infection at the site of surgery (incisional superficial, incisional deep, or organ/space infection) has been demonstrated for many surgical procedures. Nevertheless, the majority of studies centering on the quality of preoperative prophylaxis have found that a high percentage of the antimicrobials used are inappropriate for this purpose. This work discusses the scientific basis for antimicrobial prophylaxis, provides general recommendations for its correct use and specific recommendations for various types of surgery. The guidelines for surgical antimicrobial prophylaxis are based on results from well-designed studies, whenever possible. These guidelines are focussed on reducing the incidence of infection at the surgical site while minimizing the contribution of preoperative administration of antimicrobials to the development of bacterial resistance.

    Full Text Available Guy SalletDepartment of Opthamology, Aalsters Stedelijk Ziekenhuis, BelgiumAbstract: A cataract surgery technique is described in which incisions, continuous circular capsulorhexis and hydrodissection are made without the use of any viscoelastics. Two small incisions are created through which the different parts of the procedure can take place, maintaining a stable anterior chamber under continuous irrigation. Subsequent bimanual phacoemulsification can be done through these microincisions. At the end of the procedure, an intraocular lens can be inserted through the self-sealing incision under continuous irrigation. 50 consecutive cataract patients were operated on without the use of viscoelastics and then compared with a group of 50 patients who had been helped with viscoelastics. No difference in outcome, endothelial cell count or pachymetry was noted between the two groups. No intraoperative complication was encountered. Viscoless cataract surgery was a safe procedure with potential advantages.Keywords: ophthalmic visco-surgical device, viscoless cataract surgery, microincision

    2006-09-01

    Advances in computer technology have aided in the diagnostic and clinical management of complex congenital craniofacial deformities. The use of stereolithographic models has begun to replace traditional milled models in the treatment of craniofacial deformities. Research has shown that stereolithography models are highly accurate and provide added information in treatment planning for the correction of craniofacial deformities. These include the added visualization of the complex craniofacial anatomy and preoperative surgical planning with a highly accurate three-dimensional model. While the stereolithographic process has had a beneficial impact on the field of craniofacial surgery, the added cost of the procedure continues to be a hindrance to its widespread acceptance in clinical practice. With improved technology and accessibility the utilization of stereolithography in craniofacial surgery is expected to increase. This review will highlight the development and current usage of stereolithography in craniofacial surgery and provide illustration of it use.

    Surgery occupies a priority place within the organization of health services. In the IMSS around 1.4 million surgeries are performed annually and 3934 take place each day. A great part of the resources goes to obstetric interventions, since 222,928 caesarean sections were performed in 2004, and along with curettages, tubal occlusions and hysterectomies, they sum 37.6% of the surgeries performed in 2004. Abdominal deliveries (caesarean sections) were done in 39% of the pregnancies delivered in the IMSS and 8.3% were done in adolescents. Simple surgical interventions were also important. Cholecystectomies were 6 times more frequent in women aged 20 to 59 years old than in men the same age. Among the main interventions we also describe hernioplasty, appendicectomies, amygdalectomies, rhinoplasties, biopsies and circumcisions. Scarce data on complications are registered and no data is available for infections of surgical wounds. Surgical procedures are more frequent in women and in certain specialities.

    Objectives: To evaluate the related factors of dysphagia following anterior cervical spine surgery. Methods: 135 cases undergoing anterior cervical spine surgery from August 2008 to July 2010 were followed up. There were 82 males and 53 females, with a mean age of 58.2 years (range, 32 to 80 years). Of these 135 patients, 58 had cervical spondylotic myelopathy(CSM), 32 had cervical radiculopathy, 18 had cervical myeloradiculopathy, 27 had ossification posterior longitudinal ligament (OPLL). All cases were treated by the same surgical group including anterior cervical discectomy and fusion(ACDF), and/or anterior cervical compec-tomy and fusion(ACCF), and total disc replacement(TDR). 135 patients were reviewed retrospectively on their postoperative dysphagia. All cases with dysphgia accepted Methylprednisolone intravenously and correspondant therapy. Results: 135 cases were followed up, and 36(26.7%) of them had postoperative dysphagia, including 11 males and 25 females. The age of patients with dysphagia ranged from 42 to 80 years, average age was 59.6. The rest age ranged from 32 to 76, the average age was 52.3, which was more significant compared to the former(P0.05). There was no statistical significance in the surgical time, blood loss or hospital day(P>0.05). After 6 month follow-up, 35 cases (97.2%) had dysphagia cured or improved. While 1 case had improvement at 1 year follow-up. Conclusions: Female, elder, titanium plating and multiple surgical level numbers may be associated with postoperative dysphagia. As a result, clinicians should pay more attention to this complication and make proper intervention.%目的:探讨颈椎前路手术后发生吞咽困难的相关因素.方法:随访2008年8月~2010年7月收治的颈椎前路手术患者135例,其中男82例,女53例;年龄32~80岁,平均58.2岁;诊断为脊髓型颈椎病58例,神经根型颈椎病32例,混合型颈椎病18例,后纵韧带骨化症27例.入院后均由同一组医师治疗,手术方

    Robotic surgeries have developed in the general thoracic field over the past decade, and publications on robotic surgery outcomes have accumulated. However, controversy remains about the application of robotic surgery, with a lack of well-established evidence. Robotic surgery has several advantages such as natural movement of the surgeon's hands when manipulating the robotic arms and instruments controlled by computer-assisted systems. Most studies have reported the feasibility and safety of robotic surgery based on acceptable morbidity and mortality compared to open or video-assisted thoracic surgery (VATS). Furthermore, there are accumulated data to indicate longer operation times and shorter hospital stay in robotic surgery. However, randomized controlled trials between robotic and open or VATS procedures are needed to clarify the advantage of robotic surgery. In this review, we focused the literature about robotic surgery used to treat lung cancer and mediastinal tumor.

    Full Text Available The management of congenital cataract is very different to the treatment of a routine age-related cataract. In adults, surgery may be delayed for years without affecting the visual outcome. In infants, if the cataract is not removed during the first year of life, the vision will never be fully regained after surgery. In adults, if the aphakia is not corrected immediately, it can be corrected later. In young children, if the aphakia is not corrected, the vision will never develop normally.

    More than the number of real novelties, trends and preliminary results characterise the annual development in surgery. The wealth and diversity of topics to be covered require arbitrary choices, therefore not necessarily complete. The constant development of choledocolithiasis management, dominated by minimal invasive technology, treatments of unusual nature of two frequent proctological conditions, fistulae and haemorrhoids, the increasing importance of metabolic bariatric surgery, as well as the strict rules of effective melanoma treatment, represent as many directions in which the operating procedure, although unseen, continue to gain quality and security.

    Amphibian surgery has been especially described in research. Since the last decade, interest for captive amphibians has increased, so have the indications for surgical intervention. Clinicians should not hesitate to advocate such manipulations. Amphibian surgeries have no overwhelming obstacles. These patients heal well and tolerate blood loss more than higher vertebrates. Most procedures described in reptiles (mostly lizards) can be undertaken in most amphibians if equipment can be matched to the patients' size. In general, the most difficult aspect would be the provision of adequate anesthesia.

    Surgery is the gold standard treatment for patients with thyroid cancer or nodules suspicious for cancer. Open conventional approach is the standard surgical approach. However, a visible neck incision could be a concern for most young female patients, especially for patients with a history of healing with keloid or hypertrophic scars. Robotic remote access approaches have evolved into a safe and feasible approach in selected patients, providing a hidden scar with good patient satisfaction.

    The prevalence of obesity in the United States has reached epidemic proportions. With more than 30 million Americans clinically obese, the younger population has also been affected. Surgical therapy should be offered to the severely obese patient who is refractory to nonsurgical therapy, as established by the 1991 NIH Consensus Conference on Gastrointestinal Surgery for Severe Obesity. Surgery is currently the most effective therapy for weight loss. It is far more effective than any other treatment modality, both in terms of the amount of weight loss and in terms of durability in maintaining weight loss.

    Introduction of robotic surgery in the first decade of the 21 century was one of the biggest breakthroughs in surgery since the introduction of anesthesia. For the first time in history the surgeon was placed remotely from the patient and was able to operate with the device that has more degrees of freedom than human hand. Initially developed for the US Military in order to allow surgeons to be removed from the battlefield, surgical robots quickly made a leap to the mainstream medicine. One of the first surgical uses for the robot was cardiac surgery but it is urology and prostate surgery that gave it a widespread popularity Gynecologic surgeons caught on very quickly and it is estimated that 31% of hysterectomies done in the United States in 2012 will be done robotically. With over half a million hysterectomies done each year in the US alone, gynecologic surgery is one of the main driving forces behind the growth of robotic surgery Other applications in gynecology include myomectomy oophorectomy and ovarian cystectomy resection of endometriosis and lymphadenectomy Advantages of the surgical robot are clearly seen in myomectomy The wrist motion allows for better more precise suturing than conventional "straight stick" laparoscopy The strength of the arms allow for better pulling of the suture and the third arm for holding the suture on tension. Other advantage of the robot is scaling of the movements when big movement on the outside translates to very fine movement on the inside. This enables much more precise surgery and may be important in the procedures like tubal anastomosis and implantation of the ureter Three-dimensional vision provides excellent depth of field perception. It is important for surgeons who are switching from open surgeries and preliminary evidence shows that it may allow for better identification of lesions like endometriosis. Another big advantage of robotics is that the surgeon sits comfortably with his/her arms and head supported. This

    The diagnosis-related-groups (DRG) is the cost-based system for hospital reimbursement. However, the proceeds does not coincide with the costs. Aim of the study was to identify the profit, which we could gained with 147, 155, 158, 162, 165, 198 gastrointestinal surgery DRG. 30 consecutive patients, undergone to surgery in Clinica Chirurgica of L'Aquila University, had been studied. We had calculated the daily costs of medical and nursing practice, diagnostic tests, drugs, hospitalization, surgical instruments for every patient's therapy. The DRG-proceeds had been correlated with the DRG-costs. The "major gastrointestinal surgery" had not profit (147 DRG: anterior resection of rectum = -354428 Pounds, Miles = -94020 Pounds; 155 DRG: total gastrectomy = -1920641 Pounds). On the contrary, "minimal surgery" had good profits (158 DRG: hemorroidectomy with local anestesia = 1469605 Pounds;162 DRG: sutureless groin hernioplasty = 1561200 Pounds; 198 DRG: videolaparochole-cystectomy: 1208807 Pounds). The study seems to demonstrate the disparity of the reimbursement system related to DRG. However, the surgeons, as managers, must employ warily the resources for producing DRG.

  7. Decreasing strabismus surgery

    Science.gov (United States)

    Arora, A; Williams, B; Arora, A K; McNamara, R; Yates, J; Fielder, A

    2005-01-01

    Aim: To determine whether there has been a consistent change across countries and healthcare systems in the frequency of strabismus surgery in children over the past decade. Methods: Retrospective analysis of data on all strabismus surgery performed in NHS hospitals in England and Wales, on children aged 0–16 years between 1989 and 2000, and between 1994 and 2000 in Ontario (Canada) hospitals. These were compared with published data for Scotland, 1989–2000. Results: Between 1989 and 1999–2000 the number of strabismus procedures performed on children, 0–16 years, in England decreased by 41.2% from 15 083 to 8869. Combined medial rectus recession with lateral rectus resection decreased from 5538 to 3013 (45.6%) in the same period. Bimedial recessions increased from 489 to 762, oblique tenotomies from 43 to 121, and the use of adjustable sutures from 29 to 44, in 2000. In Ontario, operations for squint decreased from 2280 to 1685 (26.1%) among 0–16 year olds between 1994 and 2000. Conclusion: The clinical impression of decrease in the frequency of paediatric strabismus surgery is confirmed. In the authors’ opinion this cannot be fully explained by a decrease in births or by the method of healthcare funding. Two factors that might have contributed are better conservative strabismus management and increased subspecialisation that has improved the quality of surgery and the need for re-operation. This finding has a significant impact upon surgical services and also on the training of ophthalmologists. PMID:15774914

  8. Robotics in gynecologic surgery.

    Frick, A C; Falcone, T

    2009-06-01

    Robotic surgery has evolved from an investigational surgical approach to a clinically useful adjunct in multiple surgical specialties over the past decade. Advocates of robotic-assisted gynecologic surgery revere the system's wristed instrumentation, ergonomic positioning, and three-dimensional high-definition vision system as significant improvements over laparoscopic equipment's four degrees of freedom and two-dimensional laparoscope that demand the surgeon stand throughout a procedure. The cost, lack of haptic feedback, and the bulky size of the equipment make robotics less attractive to others. Studies evaluating outcomes in robotic-assisted gynecologic surgery are limited. Multiple small retrospective studies demonstrate the safety and feasibility of robotic hysterectomy. With increased surgeon experience, operative times are similar to, or shorter than, laparoscopic cases. Robotic assistance can facilitate suturing in laparoscopic myomectomies, and is associated with decreased blood loss and a shorter hospital stay, although may require longer operative times. Robotic assistance has also been applied to multiple procedures in the subspecialties of infertility, urogynecology and gynecologic oncology with good success and relatively low morbidity. However, further research is warranted to better evaluate the relative benefits and costs of robotic assisted gynecologic surgery.

  14. Cataract Surgery in Uveitis

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Cataract surgery in uveitic eyes is often challenging and can result in intraoperative and postoperative complications. Most uveitic patients enjoy good vision despite potentially sight-threatening complications, including cataract development. In those patients who develop cataracts, successful surgery stems from educated patient selection, careful surgical technique, and aggressive preoperative and postoperative control of inflammation. With improved understanding of the disease processes, pre- and perioperative control of inflammation, modern surgical techniques, availability of biocompatible intraocular lens material and design, surgical experience in performing complicated cataract surgeries, and efficient management of postoperative complications have led to much better outcome. Preoperative factors include proper patient selection and counseling and preoperative control of inflammation. Meticulous and careful cataract surgery in uveitic cataract is essential in optimizing the postoperative outcome. Management of postoperative complications, especially inflammation and glaucoma, earlier rather than later, has also contributed to improved outcomes. This manuscript is review of the existing literature and highlights the management pearls in tackling complicated cataract based on medline search of literature and experience of the authors.

Clinical studies evaluating apical surgery with placement of a root-end filling were included. Studies on apical surgery with orthograde root canal filling or about apicectomy alone without root-end filling were excluded, as were experimental and animal studies. Only studies with ≥ ten patients with a minimum six month follow-up period and clearly defined radiographic and clinical healing criteria, with healing reported for at least two categories of a specific prognostic factor were accepted. Studies reporting in English, German, French, Spanish, Italian, Portuguese and Scandinavian languages were included. All studies were assessed separately by two of the three authors, with disagreements resolved by discussion. Prognostic factors were divided into patient related, tooth-related or treatment-related factors. The reported percentages of healed teeth were pooled per category. The statistical method of Mantel-Haenszel was applied to estimate the odds ratios and their 95% confidence intervals. Homogeneity was assessed using Woolf's test. With regard to tooth-related factors, the following were identified as predictors of healing: absence of preoperative pain or signs, good density of the root canal filling and a periapical lesion size of ≤ 5 mm. With regard to treatment-related factors, teeth treated with the use of an endoscope tended to have higher healed rates than teeth treated without the use of an endoscope. Although the clinician may be able to control treatment

    As bariatric surgery has become more popular, more patients are undergoing body contouring surgery after massive weight loss. Many of the surgical procedures performed on the massive weight loss patient are complex and labor-intensive. Therefore, the plastic surgery unit needs to be prepared for a patient's demand. Little literature is available on how frequently patients who have undergone gastric bypass surgery receive body contouring surgery. Two hundred fifty-two subjects (out of 425 who were mailed the questionnaire) who had undergone gastric bypass surgery between 2003 and 2009 completed the questionnaire, which obtained information on body image satisfaction and frequency of body contouring surgery after massive weight loss. Of all patients, 74% desire a body contouring surgery after gastric bypass surgery. Fifty-three patients (21%) have undergone a total of 61 body contouring procedures. The most common were abdominoplasties (59%), followed by lower body lifts (20%). In contrast to a positive judgment of the general aspect of the body image satisfaction after massive weight loss, both genders are unsatisfied with body areas like abdomen/waist, breast, and thighs. Paralleling the increasing use of bariatric surgery, there is a high demand for body contouring surgery. A huge disparity exists between the number of subjects who desire a body contouring surgery and those who actually received it.

    Full Text Available Introduction: Excessive bleeding presents a risk for the patient in cardiovascular surgery. Local haemostatic agents are of great value to reduce bleeding and related complications. TachoSil (Nycomed, Linz, Austria is a sterile, haemostatic agent that consists of an equine collagen patchcoated with human fibrinogen and thrombin. This study evaluated the safety and efficacy of TachoSil compared to conventional technique.Methods: Forty-two patients scheduled for open heart surgeries, were entered to this study from August 2010 to May 2011. After primary haemostatic measures, patients divided in two groups based on surgeon’s judgment. Group A: 20 patients for whom TachoSil was applied and group B: 22 patients that conventional method using Surgicel (13 patients or wait and see method (9 cases, were performed in order to control the bleeding. In group A, 10 patients were male with mean age of 56.95±15.67 years and in group B, 9 cases were male with mean age of 49.95±14.41 years. In case group 70% (14/20 of the surgeries were redo surgeries versus 100% (22/22 in control group.Results: Baseline characteristics were similar in both groups. In TachoSil group 75% of patients required transfusion versus 90.90% in group B (P=0.03.Most transfusions consisted of packed red blood cell; 2±1.13 units in group A versus 3.11±1.44 in group B (P=0.01, however there were no significant differences between two groups regarding the mean total volume of intra and post-operative bleeding. Re-exploration was required in 10% in group A versus 13.63% in group B (P=0.67.Conclusion: TachoSil may act as a superior alternative in different types of cardiac surgery in order to control the bleeding and therefore reducing transfusion requirement.

    The purpose of this report is to increase awareness of intraoperative burns during standard procedures, to discuss their possible causes and warning signs and to provide recommendations for prevention and procedures to follow after their occurrence. A total of 19 patients associated with intraoperative burn accidents were treated surgically and analyzed after a mean follow-up of 5 +/- 3.5 months. Review included retrospective patient chart analysis, clinical examination, and technical device and equipment testing. A total of 15 patients recently underwent cardiac surgery, and 4 pediatric patients recovered after standard surgical procedures. A total of 15 patients had superficial and 4 presented with deep dermal or full-thickness burns. The average injured TBSA was 2.1 +/- 1% (range, 0.5-4%). Delay between primary surgery and consultation of plastic surgeons was 4.5 +/- 3.4 days. A total of 44% required surgery, including débridment, skin grafting or musculocutaneous gluteus maximus flaps, and the remaining patients were treated conservatively. Successful durable soft-tissue coverage of the burn region was achieved in 18 patients, and 1 patient died after a course of pneumonia. Technical analysis demonstrated one malfunctioning electrosurgical device, one incorrect positioned neutral electrode, three incidents occurred after moisture under the negative electrode, eight burns occurred during surgery while fluid or blood created alternate current pathways, five accidents were chemical burns after skin preparation with Betadine solution, and in one case, the cause was not clear. The surgical team should pay more attention to the probability of burns during surgery. Early patient examination and immediate involvement of plastic and burn surgeons may prevent further complications or ease handling after the occurrence.

  9. Advances in mucogingival surgery.

    Science.gov (United States)

    Prato, G P

    2000-01-01

    The term Mucogingival Surgery was proposed by Friedman in 1957 to indicate any surgery "designed to preserve attached gingiva, to remove frena or muscle attachment, and to increase the depth of the vestibule". The aim of this type of surgery was to maintain an adequate amount of attached gingiva and to prevent continuous loss of attachment. This philosophy was supported by many horizontal observations in humans that confirmed the need for a certain band of attached gingiva to maintain periodontal tissue in a healthy state. Subsequently, clinical and experimental studies by Wennström and Lindhe (1983) demonstrated that as long as plaque buildup is kept under careful control there is no minimum width of keratinised gingiva necessary to prevent the development of periodontal disease. These observations reduce the importance of Mucogingival Surgery. Surgical techniques are used mostly to solve aesthetic problems, since the term "Periodontal Plastic Surgery" has been suggested to indicate surgical procedures performed to correct or eliminate anatomical, developmental or traumatic deformities of the gingiva or alveolar mucosa. More recently the Consensus Report of the American Academy of Periodontology (1996) defines Mucogingival Therapy as "non surgical and surgical correction of the defects in morphology, position and/or amount of soft tissue and underlying bone". This assigns importance to non-surgical therapy and to the bone condition because of its influence on the morphology of the defects. In this respect the Mucogingival Therapy includes: Root coverage procedures, Gingival augmentation, Augmentation of the edentulous ridge, Removing of the aberrant frenulum, Prevention of ridge collapse associated with tooth extraction, Crown lengthening, Teeth that are not likely to erupt, Loss of interdental papilla which presents an aesthetic and/or phonetic problem.

    2012-07-01

    Robotic surgery is gaining widespread popularity due to advantages such as reduced blood loss, reduced postoperative pain, shorter hospital stay and better visualisation of fine structures. Robots are being used in urological, cardiac, thoracic, orthopaedic, gynaecological and general surgery. Robotic surgery received US Food and Drug Administration approval for use in gynaecological surgery in 2005. The various gynaecological robotic operations being performed are myomectomy, total and supracervical hysterectomy, ovarian cystectomy, sacral colpopexy, tubal reanastomosis, lymph node dissection, surgery of retroperitoneal ectopic pregnancy, Moskowitz procedure and endometriosis surgery. The anaesthetic considerations include difficult access to the patient intraoperatively, steep Trendelenburg position, long surgical duration and the impact of pneumoperitoneum. We highlight the complications encountered in these surgeries and methods to prevent these complications. Robotic gynaecological surgery can be safely performed after considering the physiological effects of the steep Trendelenburg position and of pneumoperitoneum. The benefits of the surgical procedure should be weighed against the risks in patients with underlying cardiorespiratory problems.

    At the beginning of the 20th century, the development of safer anesthesia, antiseptic techniques, and meticulous surgical dissection led to a substantial decrease in operative risk. In turn, the scope of surgery expanded to include elective procedures performed with the intention of improving the quality of life of patients. Between 1908 and 1912, Harvey Cushing performed 3 dorsal rhizotomies to improve the quality of life of 3 patients with debilitating neuralgia: a 54-year-old man with "lightning" radicular pain from tabes dorsalis, a 12-year-old boy cutaneous hyperesthesia and spasticity in his hemiplegic arm, and a 61-year-old man with postamputation neuropathic pain. Symptomatic improvement was seen postoperatively in the first 2 cases, although the third patient continued to have severe pain. Cushing also removed a prominent spinous process from each of 2 patients with debilitating headaches; both patients, however, experienced only minimal postoperative improvement. These cases, which have not been previously published, highlight Cushing's views on the role of surgery and illustrate the broader movement that occurred in surgery at the time, whereby elective procedures for quality of life became performed and accepted.

    PROXIMAL JUNCTIONAL KYPHOSIS (PJK) IS DEFINED AS: 1) Proximal junction sagittal Cobb angle >≥10°, and 2) Proximal junction sagittal Cobb angle of at least 10° greater than the pre-operative measurement PJK is a common complication which develops in 39% of adults following surgery for spinal deformity. The pathogenesis, risk factors and prevention of this complication are unclear. Of 54 consecutive adults treated with spinal deformity surgery (age≥59.3±10.1 years), 19 of 54 (35%) developed PJK. The average follow-up was 26.8 months (range 12 - 42). Radiographic parameters were measured at the pre-operative, early postoperative (4-6 weeks), and final follow-up visits. Sagittal alignment was measured by the ratio between the C7-plumbline and the sacral-femoral distance. Binary logistic regression model with predictor variables included: Age, BMI, C7-plumbline, and whether lumbar lordosis, thoracic kyphosis and sacral slope were present Patients who developed PJK and those without PJK presented with comparable age, BMI, pelvic incidence and sagittal imbalance before surgery. They also presented with comparable sacral slope and lumbar lordosis. The average magnitude of thoracic kyphosis was significantly larger than the lumbar lordosis in the proximal junctional kyphosis group, both at baseline and in the early postoperative period, as represented by [(-lumbar )lordosis - (thoracic kyphosis)]; no- PJK versus PJK; 6.6°±23.2° versus -6.6°±14.2°; p≥0.012. This was not effectively addressed with surgery in the PJK group [(-LL-TK): 6.2°±13.1° vs. -5.2°±9.6°; p≥0.004]. This group also presented with signs of pelvic retroversion with a sacral slope of 29.3°±8.2° pre-operatively that was unchanged after surgery (30.4°±8.5° postoperatively). Logistic regression determined that the magnitude of thoracic kyphosis and sagittal balance (C7-plumbline) was the most important predictor of proximal junctional kyphosis.

    Training of the hand surgeon HAND SURGEON A CONCEPT: The hand surgeon is supposed to be in charge of all the hand lesions regarding, skeleton, muscles, tendons, nerves and vessels. He has to be able to insure reparation and coverage of all of them. So he is involved in all the structures, which insure integrity and function of the hand. PURPOSE AND WAYS OF TRAINING: To obtain the asked ability, the hand surgeon training has to be global and sustained by two underlying surgical specialities: orthopedic surgery and plastic and reconstructive surgery. From 2000 after many years of dealings, a Right to the Title in Hand Surgery was born. This Right to the Title wants to be the formal recognition of the specific training of the hand surgeon. For the well-recognized ancient hand surgeons they need to be confirmed by one's peers. Now a day the hand surgeon has to satisfy to this specific training: Passed the complete training and exam of the Orthopedic or Plastic surgery board. Spent at least 6 months as resident in the other underlying specialty. Passed a microsurgery examination. Passed one of the four national Hand Surgery diplomas (DIU/Inter-Universitary Diploma). The examinations have been harmonized. A common formation is delivered regarding hand surgery, the way of examination is the same and the formation is 2 years long. The final exam is presented in front of board of examiners where a teacher of one of the other three national diplomas is present. Spent at least 2 years in a formative hand surgery unit, listed by the French College of Hand Surgeons, as senior surgeon. Those requirements are heavy to assume and need a heavy personal involvement. That seems to be necessary to have an ability level as high as possible. Emergency surgery practice is absolutely necessary in this training. All the 17 university formative hand surgery units listed by the French College of Hand Surgeons are members of the FESUM (European Federation of the Emergency Hand Units

    Transoral robotic surgery (TORS) is a technique used to treat oral, throat, and skull base cancers using a minimally invasive robotic approach through the mouth and throat. The TORS procedure allows deeper access and dissection of suspicious lesions and neoplastic growths in the oral cavity and those that extend from the throat to the base of the skull. Robotic surgery allows the surgeon to operate in tight spaces without a large open incision. This article discusses symptoms and risk factors of oral, throat, and skull base cancers; types of procedures that can be performed using the TORS approach; specialized instrumentation; patient selection; surgical advantages and disadvantages; patient benefits; and the role of the surgical team in preparing to intraoperatively care for the TORS patient.

    Cosmetic eyelid surgery is becoming increasingly popular. It can rejuvenate the patient's appearance with relatively minor side effects. Its risk/benefit ratio is one of the best in facial cosmetic surgery. However, the patient does not always accurately assess the aesthetic appearance of his or her eyelids. This underscores the importance of clinical examination in order to determine the patient's wishes, and then make an accurate diagnosis and potential surgical plan. We currently oppose, in general, surgical techniques involving tissue removal (skin-muscle and/or fat) in favor of those involving tissue repositioning and grafting (autologous fat pearl transposition, obtained by liposuction, and lipostructure). Furthermore, the place of adjuvant therapies to blepharoplasty is steadily increasing. They mainly include surface treatments (peels and lasers), dermal fillers and anti-wrinkle botulinum toxin injections. They are also increasingly used in isolation in novel ways. In all cases, a perfect knowledge of anatomy and relevant skills and experience remain necessary.

  5. Cataract Surgery Tool

    Science.gov (United States)

    1977-01-01

    The NASA-McGannon cataract surgery tool is a tiny cutter-pump which liquefies and pumps the cataract lens material from the eye. Inserted through a small incision in the cornea, the tool can be used on the hardest cataract lens. The cutter is driven by a turbine which operates at about 200,000 revolutions per minute. Incorporated in the mechanism are two passages for saline solutions, one to maintain constant pressure within the eye, the other for removal of the fragmented lens material and fluids. Three years of effort have produced a design, now being clinically evaluated, with excellent potential for improved cataract surgery. The use of this tool is expected to reduce the patient's hospital stay and recovery period significantly.

    The purpose of this article was to provide the literature regarding the psychological stress in the peri-operative period of adult patients undergoing operations under general anesthesia. The articles were obtained by surveying the papers published and catalogued in the Medline Pubmed interface database, Lilacs and the Biblioteca Virtual de Saúde (BVS) since 1984, crossing the headings stress, surgery, general anesthesia, psychology. Over 800 articles related to stress and surgery were analyzed with regards to their relevance to the considered subject. Eighteen articles were related to psychological stress. Their results confirmed the presence of psychological and physical stress, during the peri-operative period as well as relation between stress and de clinical post-operative recovery. There is a gap regarding in the peri-operative period. More studies on psychological influence on stress may benefit patients and help professionals during the surgical treatment.

    2003-12-01

    A renaissance in cardiac surgery has begun. The early clinical experience with computer-enhanced telemanipulation systems outlines the limitations of this approach despite some procedural success. Technologic advancements, such as the use of nitinol U-clips (Coalescent Surgical Inc., Sunnyvale, CA) instead of sutures requiring manual knot tying, have been shown to decrease operative times significantly. It is expected that with further refinements and development of adjunct technologies, the technique of computer-enhanced endoscopic cardiac surgery will evolve and may prove to be beneficial for many patients. Robotic technology has provided benefits to cardiac surgery. With improved optics and instrumentation, incisions are smaller. The ergometric movements and simulated three-dimensional optics project hand-eye coordination for the surgeon. The placement of the wristlike articulations at the end of the instruments moves the pivoting action to the plane of the mitral annulus. This improves dexterity in tight spaces and allows for ambidextrous suture placement. Sutures can be placed more accurately because of tremor filtration and high-resolution video magnification. Furthermore, the robotic system may have potential as an educational tool. In the near future, surgical vision and training systems might be able to model most surgical procedures through immersive technology. Thus, a "flight simulator" concept emerges where surgeons may be able to practice and perform the operation without a patient. Already, effective curricula for training teams in robotic surgery exist. Nevertheless, certain constraints continue to limit the advancement to a totally endoscopic computer-enhanced mitral valve operation. The current size of the instruments, intrathoracic instrument collisions, and extrathoracic "elbow" conflicts still can limit dexterity. When smaller instruments are developed, these restraints may be resolved. Furthermore, a working port incision is still required for

    The port-access technique for cardiac surgery was recently developed at Stanford University in California as a less invasive method to perform some cardiac operations. The port-access system has been described in detail elsewhere. It is based on femoral arterial and venous access for cardiopulmonary bypass (CPB) and on the adoption of a specially designed triple-lumen catheter described originally by Peters, and subsequently modified and developed in the definitive configuration called the endoaortic clamp.

    If (a revision of) a conventional endodontic treatment is not possible or not successful, apical endodontic surgery can be indicated. The contemporary indications, the better retrograde preparation techniques with ultrasonic retro-tips, and the better visualisation of the operation area with an operation microscope can lead to higher success percentages. Moreover, the current developments in the field of compatible filling materials are promising. Also the application of lasers is promising, but has still to prove its clinical usefulness.

    2010-05-01

    In the therapeutic approach to complex glaucomas different initial situations were considered: pre-existing glaucoma, induction of glaucoma after vitreoretinal surgery and antiglaucomatous procedures. In pre-existing glaucoma and after filtering surgery maintenance of the filtering bleb requires a vitreoretinal approach for conjunctiva preservation with techniques such as pneumatic retinopexy or small gauge vitrectomy. After vitreoretinal surgery an increase in intraocular pressure (IOP) is common. Secondary glaucoma may occur after scleral buckling and after vitrectomy with or without gas or silicone oil tamponade as well as after application of steroids. Angle closure glaucoma after scleral buckling develops because of congestion and anterior rotation of the ciliary body. Vitreous tamponades with expansive or saturated gases may cause angle-closure glaucoma with or without pupillary blockage and may critically shorten ocular perfusion. Postoperative checks, immediate action and a ban on boarding aircraft over the period of intraocular gas tamponade prevent permanent damage to the eye. The majority of secondary glaucomas can effectively be controlled by topical medication and adequate postoperative posture of the patient. Besides the temporary use of systemic antiglaucomatous medication or laser therapy, very rarely in cases of massive swelling or overfill, a direct intervention, such as partial gas or silicone oil removal is required. A prophylactic inferior peripheral iridectomy prevents pupillary blockage in aphakic eyes with intraocular tamponade. In cases of heavy silicone oil use, the peripheral iridectomy is placed in the superior position. Nd:YAG laser application will regulate IOP in cases of occlusion. Secondary glaucoma due to silicone oil emulsification overload is treated by trabecular meshwork aspiration and lavage. In refractory glaucoma repetitive cyclophotocoagulation and drainage implants represent an approved method for long-term IOP regulation

    2012-02-03

    OBJECTIVES: To describe the profound alterations in host immunity that are produced by major surgery as demonstrated by experimental and clinical studies, and to evaluate the benefits of therapeutic strategies aimed at attenuating perioperative immune dysfunction. DATA SOURCES: A review of the English-language literature was conducted, incorporating searches of the MEDLINE, EMBASE, and Cochrane collaboration databases to identify laboratory and clinical studies investigating the cellular response to surgery. STUDY SELECTION: Original articles and case reports describing immune dysfunction secondary to surgical trauma were included. DATA EXTRACTION: The results were compiled to show outcomes of different studies and were compared. DATA SYNTHESIS: Current evidence indicates that the early systemic inflammatory response syndrome observed after major surgery that is characterized by proinflammatory cytokine release, microcirculatory disturbance, and cell-mediated immune dysfunction is followed by a compensatory anti-inflammatory response syndrome, which predisposes the patient to opportunistic infection, multiple organ dysfunction syndrome, and death. Because there are currently no effective treatment options for multiple organ dysfunction syndrome, measures to prevent its onset should be initiated at an early stage. Accumulating experimental evidence suggests that targeted therapeutic strategies involving immunomodulatory agents such as interferon gamma, granulocyte colony-stimulating factor, the prostaglandin E(2) antagonist, indomethacin, and pentoxifylline may be used for the treatment of systemic inflammatory response syndrome to prevent the onset of multiple organ dysfunction syndrome. CONCLUSIONS: Surgical trauma produces profound immunological dysfunction. Therapeutic strategies directed at restoring immune homeostasis should aim to redress the physiological proinflammatory-anti-inflammatory cell imbalance associated with major surgery.

    The indication of bariatric surgery as therapeutic procedure for morbid obese patients requires the application of selection criteria which deal with the degree of obesity, associated complications and previous failure of conventional therapy. Alcohol or drug addiction and concomitant serious disease are contraindications for bariatric surgery. Before operation, a full assessment is needed to identify possible eating behaviour disturbances and associated comorbidity such as cardiovascular disease, sleep apnoea, metabolic and psychiatric alterations which might induce intra and postoperative complications. Surgical techniques can be classified as restrictive, malabsortive and mixed procedures. Gastroplasty and adjustable gastric banding are restrictive techniques, which are indicated in obese patients with body mass index less than 45 kg/m2. Mixed techniques are the most used procedures. They include gastric by-pass which causes a reduction of 60-70% of weight excess, biliopancreatic diversion and duodenal switch which can eliminate a 75% of body weight excess. Following bariatric surgery a dramatic improvement in associated comorbidity can be demonstrated, specially in what refers to diabetes, hypertension, dislipidaemia and apnoea. Postoperative mortality is around 1-2%. Peritonitis and venous thromboembolism are the most serious complications. Postoperative follow-up should be lifelong and requires a progressive nutrition planning and vitamin supplementation.

    Full Text Available Abstract Minimally invasive surgery (MIS can be considered as the greatest surgical innovation over the past thirty years. It revolutionized surgical practice with well-proven advantages over traditional open surgery: reduced surgical trauma and incision-related complications, such as surgical-site infections, postoperative pain and hernia, reduced hospital stay, and improved cosmetic outcome. Nonetheless, proficiency in MIS can be technically challenging as conventional laparoscopy is associated with several limitations as the two-dimensional (2D monitor reduction in-depth perception, camera instability, limited range of motion and steep learning curves. The surgeon has a low force feedback which allows simple gestures, respect for tissues and more effective treatment of complications.Since 1980s several computer sciences and robotics projects have been set up to overcome the difficulties encountered with conventional laparoscopy, to augment the surgeon's skills, achieve accuracy and high precision during complex surgery and facilitate widespread of MIS. Surgical instruments are guided by haptic interfaces that replicate and filter hand movements. Robotically assisted technology offers advantages that include improved three- dimensional stereoscopic vision, wristed instruments that improve dexterity, and tremor canceling software that improves surgical precision.

    The objectives of this study were to assess the applicability of patents and publications as metrics of surgical technology and innovation; evaluate the historical relationship between patents and publications; develop a methodology that can be used to determine the rate of innovation growth in any given health care technology. The study of health care innovation represents an emerging academic field, yet it is limited by a lack of valid scientific methods for quantitative analysis. This article explores and cross-validates 2 innovation metrics using surgical technology as an exemplar. Electronic patenting databases and the MEDLINE database were searched between 1980 and 2010 for "surgeon" OR "surgical" OR "surgery." Resulting patent codes were grouped into technology clusters. Growth curves were plotted for these technology clusters to establish the rate and characteristics of growth. The initial search retrieved 52,046 patents and 1,801,075 publications. The top performing technology cluster of the last 30 years was minimally invasive surgery. Robotic surgery, surgical staplers, and image guidance were the most emergent technology clusters. When examining the growth curves for these clusters they were found to follow an S-shaped pattern of growth, with the emergent technologies lying on the exponential phases of their respective growth curves. In addition, publication and patent counts were closely correlated in areas of technology expansion. This article demonstrates the utility of publically available patent and publication data to quantify innovations within surgical technology and proposes a novel methodology for assessing and forecasting areas of technological innovation.

    The impact of health and disease has led many artists to depict these themes for thousands of years. Specifically, epilepsy has been the subject of many famous works, likely because of the dramatic and misunderstood nature of the clinical presentation. It often evokes religious and even mythical processes. Epilepsy surgical treatment has revolutionized the care of selected patients and is a relatively recent advance. Epilepsy surgery has been depicted in very few artistic works. The first portrait showing a potential surgical treatment for patients with epilepsy was painted in the 12th century. During the Renaissance, Bosch famously provided artistic commentary on traditional beliefs in "The stone of madness". Several of these works demonstrate a surgeon extracting a stone from a patient's head, at one time believed to be the source of all "folly", including epileptic seizures, psychosis, intellectual disability, depression, and a variety of other illnesses. There are some contemporary art pieces including themes around epilepsy surgery, all of them depicting ancient Inca Empire procedures such as trepanning. This article reviews the most relevant artistic works related with epilepsy surgery and also its historical context at the time the work was produced. We also present a painting from the Mexican artist Eduardo Urbano Merino that represents the patient's journey through refractory epilepsy, investigations, and ultimately recovery. Through this work, the artist intends to communicate hope and reassurance to patients going through this difficult process.

    2017-02-01

    Early onset scoliosis can be both a disfiguring as well as a life threatening condition. When more conservative treatments fail, pediatric spinal surgeons are forced to consider operative interventions. Traditionally, these interventions have involved the insertion of a variety of implants into the patient with a limited number of anchor points controlling the spine. In the past, these pediatric patients have had multiple surgeries for elective lengthening of these devices to facilitate their growth while attempting to control the scoliosis. These patients often experience a physical and emotional toll from their multiple repeated surgeries. Growing spine techniques have also had a noted high complication rate due to implant dislodgement and infections. Recently, the development of non-invasively, self-lengthening growing rods has occurred. These devices have the potential to allow for the devices to be lengthened magnetically in a conscious patient in the surgeon's office. Areas covered: This review summarized previously published articles in the English literature using a key word search in PubMed for: 'magnetically controlled growing rods', 'Magec rods', 'magnetic growing rods' and 'growing rods'. Expert commentary: Magnetically controlled growing rods have an advantage over growing rods in lengthening the growing spine in the absence of repetitive surgeries.

    Obesity is a source of major morbidity and mortality and is a growing concern worldwide. Maternal obesity is associated with increased maternal and fetal risks during pregnancy. Bariatric surgery has emerged as one of the most sustainable treatments for severe obesity and its comorbidities. Patients who have undergone bariatric surgery often experience drastic improvements in hypertension and diabetes. It is not surprising, therefore, that the incidence of bariatric surgery is increasing, particularly in women of childbearing age. In fact, many women undergoing bariatric surgery plan to become pregnant in the future. Bariatric surgery may have a beneficial effect on rates of fetal macrosomia, gestational diabetes, hypertension, and preeclampsia. Conversely, studies have showed that bariatric surgery may increase the risk of small for gestational age infants and preterm birth. Given its rising incidence, it is important that physicians be able to thoroughly and accurately counsel and treat patients who plan to, or do, become pregnant after bariatric surgery.

    Back pain is experienced by up to of 85% of the United States population. Most often it resolves with minimal to no medical treatment. For those whose pain endures, worsens, or becomes protracted, conservative care is typically first attempted. Individuals who continue to experience significant back pain are often considered for surgical procedures, the results of which are not uniformly positive. The consequences of failed surgical intervention can be quite devastating, and psychosocial factors have been found to predict poor outcome. The literature on psychosocial risk factors for failed back surgery is reviewed first, identifying psychological dysfunction in the domains of emotions, cognitions, behavior, and interpersonal processes as increasing the risk for failed back surgery. Empirical findings with the MMPI-2 Restructured Form (MMPI-2-RF) are presented next, including descriptive analyses with a sample of 1341 individuals assessed as part of a pre-surgical psychological screening. Correlations between MMPI-2-RF scale scores and measures of the primary risk factors identified in this review are reported for a smaller sample of 197 pre-surgical candidates. Interpretive implications of the MMPI-2-RF findings are discussed along with suggestions for further research in this area.

    Study Design Prospective cohort study. Objectives To analyze the effectiveness and practicality of using cancellous bone substitute with platelet-rich plasma (PRP) in posterolateral arthrodesis. Methods Twenty consecutive patients underwent posterolateral arthrodesis with implantation of cancellous bone substitute soaked with PRP obtained directly in the operating theater on the right hemifield and cancellous bone substitute soaked with saline solution on the right. Results Computed tomography scans at 6 and 12 months after surgery were performed in all patients. Bone density was investigated by comparative analysis of region of interest. The data were analyzed with repeated-measures variance analyses with value of density after 6 months and value of density after 12 months, using age, levels of arthrodesis, and platelet count as covariates. The data demonstrated increased bone density using PRP and heterologous cancellous block resulting in an enhanced fusion rate during the first 6 months after surgery. Conclusions PRP used with cancellous bone substitute increases the rate of fusion and bone density joining osteoinductive and osteoconductive effect.

    Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

    Injuries of the axial skeleton are an important field of work within orthopaedic surgery and traumatology. Most lesions following trauma may be diagnosed by means of conventional plain radiography, computed tomography or magnetic resonance imaging. However, for some aspects SPECT/ CT can be helpful even in a trauma setting. In particular, the combination of highly sensitive but nonspecific scintigraphy with nonsensitive but highly specific computed tomography makes it particularly useful in anatomically complex regions such as the pelvis and spine. From a trauma surgeon's point of view, the four main indications for nuclear medicine imaging are the detection of (occult) fractures, and the imaging of inflammatory bone and joint diseases, chronic diseases and postoperative complications such as instability of instrumentation or implants. The aim of the present review was to give an overview of the adoption of SPECT/CT in a clinical setting. (orig.)

    Full Text Available Introduction. The systems of energy in surgery are applied in order to achieve better and more effective performing of procedures. Whereas various energy sources, including electricity, ultrasound, laser and argon gas, may be used, the fundamental principle involves tissue necrosis and hemostasis by heating. Electro Surgery. Electro Surgery is a surgical technique by which surgical procedures are performed by focused heating of the tissue using devices based on high-frequency currents. It represents one of the most frequently used energy systems in laparoscopy. Ultrasound Energy. The basic principle of operation of the ultrasound surgical instruments is the usage of low-frequency mechanic vibrations (ultrasound energy within the range of 20-60 kHz for cutting and coagulation of tissue. Laser. Laser is the abbreviation for Light Amplification by Stimulated Emission of Radiation, aimed at increasing light by stimulated emission of radiation and it is the name of the instrument which generates coherent beam of light. Argon Plasma Coagulation. It has been in use since 1991 for endoscopic hemostasis. It uses highfrequency electric current and ionized gas argon. The successful application of devices depends on the type of surgical procedure, training of the surgeon and his knowledge about the device. Surgeons do not agree on the choice of device which would be optimal for a certain procedure. Conclusion. The whole team in the operating room must have the basic knowledge of the way an energy system works so as to provide a safe and effective treatment of patients. The advantages and shortcomings of different systems of energy have to be taken into account while we use a special mode.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Minor surgery is small surgery or localized example cut ulcers and boils, cyst excision, and suturing. Somethings that need to be considered in the preparation of the surgery is minor tools, operating rooms and operating tables, lighting, maintenance of tools and equipment, sterilization and desinfection equipment, preparation of patients and anesthesia. In general cysts is walled chamber that consist of fluid, cells and the remaining cells. Cysts are formed not due to inflammation although then be inflamed. Lining of the cysts wall is composed of fibrous tissue and usually coated epithelial cells or endothelial. Cysts formed by dilated glands and closed channels, glands, blood vessels, lymph channels or layers of the epidermis. Contents of the cysts wall consists of the results is serum, lymph, sweat sebum, epithelial cells, the stratum corneum, and hair. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    Colorectal pediatric surgery is a diverse field that encompasses many different procedures. The pullthrough for Hirschsprung disease, the posterior sagittal anorectoplasty for anorectal malformations including complex cloaca reconstructions and the ileal pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis present some of the most technically challenging procedures pediatric surgeons undertake. Many children prevail successfully following these surgical interventions, however, a small number of patients suffer from complications following these procedures. Anticipated postoperative problems are discussed along with medical and surgical strategies for managing these complications. Copyright © 2016 Elsevier Inc. All rights reserved.

    Orthopedic surgery in rabbits poses several unique parameters for the veterinary surgeon. It is imperative for the veterinarian to be knowledgeable about the anatomic features of the surgical repair site and to become familiar with a rabbit's pain and discomfort often associated with orthopedic injuries. Handling the perioperative and postoperative pain and potential GI disturbances are crucial for a successful outcome of the surgical case. This article is designed to help the veterinary surgeon prepare for the orthopedic surgical procedure and the peripheral physiologic needs of the rabbit from presentation through recovery.

    Minimally invasive surgery has been shown to offer many advantages to general surgical patients but has not been widely adopted for colorectal disease. Initial fears surrounding the oncological safety of laparoscopic colectomies have largely subsided but the technical challenges still remain. Surgical robots or telemanipulators present the laparoscopic surgeon with unrivaled dexterity and vision, which may allow colonic resections to be completed with greater ease. Although initial studies suggest promising results using currently available systems, it will take further time for patient benefits to be proven, therefore justifying the greater expense of operating with this new technology.

    Temporomandibular joint (TMJ) disorders are a common disease and may be responsible for major functional and painful repercussions. Treatment is not consensual. The literature highlights the role of conservative treatments (physiotherapy, analgesics, splints) in a first attempt. Minimally invasive surgical techniques (arthroscopy, arthrocentesis) have developed rapidly in recent decades. They have proven effective and reliable, especially in patients suffering from irreducible or reducible anterior disc dislocation or presenting with arthopathies. The goal of our work was to make an update about disk surgery. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Despite the extensive use of robotics in the adult population, the use of robotics in pediatrics has not been well accepted. There is still a lack of awareness from pediatric surgeons on how to use the robotic equipment, its advantages and indications. Benefit is still controversial. Dexterity and better visualization of the surgical field are one of the strong values. Conversely, cost and a lack of small instruments prevent the use of robotics in the smaller patients. The aim of this manuscript is to present the controversies about the use of robotics in pediatric surgery.

  18. Anesthesia for thoracoscopic surgery

    Full Text Available Anesthesia for thoracoscopy is based on one lung ventilation. Lung separators in the airway are essential tools. An anatomical shunt as a result of the continued perfusion of a non-ventilated lung is the principal intraoperative concern. The combination of equipment, technique and process increase risks of hypoxia and dynamic hyperinflation, in turn, potential factors in the development of an unusual form of pulmonary edema. Analgesia management is modelled on that shown effective and therapeutic for thoracotomy. Perioperative management needs to reflect the concern for these complex, and complicating, processes to the morbidity of thoracoscopic surgery.

    Abstract Background: Mucormycosis is a rare, aggressive, and life-threatening infection that is caused by organisms belonging to the order Mucorales. It is usually acquired through direct means and virtually always affects immunocompromised patients with the port of entry reflecting the site of infection, in this case, cutaneous. Unlike other mucormycoses, patients affected by Apophysomyces elegans (A elegans) are known to be immunocompetent. This locally aggressive disease penetrates through different tissue plains invading adjacent muscles, fascia, and even bone causing extensive morbidity and may prove fatal if treated inadequately. Cutaneous mucormycosis is associated with disruption of cutaneous barriers such as trauma. However, rarely, it may be iatrogenic. No cases have been previously reported postcosmetic surgery, especially one that is so commonly performed, lipofilling. Case Report: The patient is a, previously healthy, 41-year-old middle-eastern female who was admitted to the plastic surgery department 17 days after undergoing cosmetic surgery. She suffered from extensive tissue inflammation and necrosis in both gluteal regions. Following admission, she was initially started on empirical antimicrobial therapy which was changed to an antifungal agent, voriconazole, when preliminary microbiological results showed filamentous fungi. This was discontinued and liposomal amphotericin B was commenced when further mycological analysis identified A elegans. Furthermore, she underwent a total of 10 sessions of extensive debridement to the extent that portions of the sacrum and left femoral head became exposed. Her clinical status and wounds improved with the appropriate management and she remained an inpatient for 62 days. Subsequently, she had defects in both gluteal regions which required reconstructive surgery. Conclusion: A elegans is an uncommon cause of iatrogenic cutaneous mucormycosis. A high index of clinical suspicion is required, especially in the
