    2008-01-01

    Objective To investigate the management and outcome of cerebrospinal fluid leakage (CSFL) after cervical surgery. Methods Medical records of 642 patients who underwent cervical surgery between December 1999 and December 2005 at our hospital were retrospectively reviewed. Five patients complicated by CSFL after surgery were enrolled, of which 4 cases were complicated after ossified posterior longitudinal ligament or posterior vertebral osteophyte resection directly injuring the dura, and 1 case after posterior cervical double-door laminoplasty with out observed dural injury during surgery. Of the 5 CSFL cases, 4 cases occurred at 1-3 days after operation and 1 case at 9 days after operation. All 5 postoperative CSFL cases were treated through wound drainage removal, wound sutures, prophylactic antibiotics, and continuous subarachnoid drainage in the elevated head position.Results All 5 CSFL cases experienced leakage cessation within 1-3 days and wound healing within 4-8 days, and subarachnoid drainage lasted 11-16 days with an average volume of 320 mL (range, 150-410 mL). Four cases experienced headache, nausea and vomiting, 1 case suffered from somnolence and hyponatremia, and symptoms subsided after symptomatic treatment and intravenous fluid administration. All patients were followed up for an average of 32 months (range, 22-50 months). No occurrence of cerebrospinal fluid cyst or wound infection was observed. CSFL produced no significant negative effects upon neuromuscular function recovery.Conclusion Continuous subarachnoid cavity drainage in combination with elevated head position is a simple and safe non-surgical method in treatment of CSFL following cervical surgery.

    Full Text Available Chordomas are neoplasms that arise from notochord embryonic remnants, been the sacrococcygeal spine the main site of involvement; the cervical spine site is uncommon and it account for less than 10% of chordomas. Because of their slow growth, the diagnosis is delayed until they reach a large size, despite which they are locally aggressive tumours due to their relation to critical neurovascular structures and present a high rate of local recurrence. Radical surgery is the elective treatment and proton radiotherapy is used when residual tumour tissue and recurrences.Because of the uncommonness of this pathology, we report a case of a patient with cervical chordoma.

    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.

    Full Text Available Background : Intraoperative somatosensory evoked potential (SSEP monitoring during cervical spine surgery is not a universally accepted standard of care. Our retrospective study evaluated the efficacy and cost-effectiveness of intraoperative SSEP in a single surgeon′s practice. Materials and Methods : Intraoperative SSEP monitoring was performed on 210 consecutive patients who had cervical spine surgery: anterior cervical approach 140 and posterior approach 70. They were screened for degradation or loss of SSEP data. A cost analysis included annual medical costs for health and human services, durable goods and expendable commodities. Results : Temporary loss of the electrical wave during cauterization resolved upon discontinuation of the cautery. We had no loss of cortical wave with preservation of the popliteal potential. A drop in the amplitude of the cortical wave was observed in three patients. This drop was resolved after hemodynamic stabilization in the first patient, readjusting the bone graft in the second patient, and interrupting the surgery in the third patient. The additional cost for SSEP monitoring was $835 per case and the total cost of the surgery was $13,835 per case. By spending $31,546 per year on SSEP, our institution is saving a total cost ranging from $64,074 to $102,192 per patient injured per year. Conclusion : Intraoperative SSEP monitoring is a reliable and cost-effective method for preventing postoperative neurological deficit by the early detection of vascular or mechanical compromise, and the immediate alteration of the anesthetic or surgical technique.

  16. 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.

    OBJECTIVE Esophageal perforation is a rare but well-known complication of anterior cervical spine surgery. The authors performed a systematic review of the literature to evaluate symptomatology, direct causes, repair methods, and associated complications of esophageal injury. METHODS A PubMed search that adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines included relevant clinical studies and case reports (articles written in the English language that included humans as subjects) that reported patients who underwent anterior spinal surgery and sustained some form of esophageal perforation. Available data on clinical presentation, the surgical procedure performed, outcome measures, and other individual variables were abstracted from 1980 through 2015. RESULTS The PubMed search yielded 65 articles with 153 patients (mean age 44.7 years; range 14-85 years) who underwent anterior spinal surgery and sustained esophageal perforation, either during surgery or in a delayed fashion. The most common indications for initial anterior cervical spine surgery in these cases were vertebral fracture/dislocation (n = 77), spondylotic myelopathy (n = 15), and nucleus pulposus herniation (n = 10). The most commonly involved spinal levels were C5-6 (n = 51) and C6-7 (n = 39). The most common presenting symptoms included dysphagia (n =63), fever (n = 24), neck swelling (n = 23), and wound leakage (n = 18). The etiology of esophageal perforation included hardware failure (n = 31), hardware erosion (n = 23), and intraoperative injury (n = 14). The imaging modalities used to identify the esophageal perforations included modified contrast dye swallow studies, CT, endoscopy, plain radiography, and MRI. Esophageal repair was most commonly achieved using a modified muscle flap, as well as with primary closure. Outcomes measured in the literature were often defined by the time to oral intake following esophageal repair. Complications included

    2016-06-01

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    2010-01-01

    Full Text Available Idiopathic internal jugular phlebectasia, occurs either unilaterally or bilaterally affecting the internal jugular vein is a rare congenital variation often diagnosed during childhood. It usually presents with a benign swelling over the lateral side of neck on the affected side, seen on exertion. A-30-year old male was operated for anterior cervical dissectomy from right lateral approach and was diagnosed per-operatively as internal jugular phlebectasia.The surgery was abandoned at this stage on the advice of cardiothoracic surgeon to investigate the patient for the secondary etiological factors for internal jugular vein dilatation. The patient was reassured without any active intervention for the phlebectasia and cervical dissectomy was performed in the second surgery through the lateral approach from left side. This case is presented in view of rarity and suggested that during preoperative workup the nearby structures like carotid sheath should be evaluated by magnetic resonance imaging to avoid such per-operative surprises.

    Treatment-requiring diseases of the cervical spine in children are rare. The most common cases requiring medical assessment and treatment are acute torticollis and various accidents. A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

    Study Design Case report. Objective There is a paucity of literature describing the use of bone graft substitutes to achieve fusion in the pediatric cervical spine. The outcomes and complications involving the off-label use of bone morphogenetic protein (BMP)-2 in the pediatric cervical spine are not clearly defined. The purpose of this article is to report successful fusion without complications in two pediatric patients who had instrumented occipitocervical fusion using low-dose BMP-2. Methods A retrospective review of the medical records was performed, and the patients were followed for 5 years. Two patients under 10 years of age with upper cervical instability were treated with occipitocervical instrumented fusion using rigid occipitocervical fixation techniques along with conventionally available low-dose BMP-2. A Medline and PubMed literature search was conducted using the terms "bone morphogenetic protein," "BMP," "rh-BMP2," "bone graft substitutes," and "pediatric cervical spine." Results Solid occipitocervical fusion was achieved in both pediatric patients. There were no reported perioperative or follow-up complications. At 5-year follow-up, radiographs in both patients showed successful occipital cervical fusion without evidence of instrumentation failure or changes in the occipitocervical alignment. To date, there are few published reports on this topic. Complications and the appropriate dosage application in the pediatric posterior cervical spine remain unknown. Conclusions We describe two pediatric patients with upper cervical instability who achieved successful occipital cervical fusion without complication using off-label BMP-2. This report underscores the potential for BMP-2 to achieve successful arthrodesis of the posterior occipitocervical junction in pediatric patients. Use should be judicious as complications and long-term outcomes of pediatric BMP-2 use remain undefined in the existing literature. PMID:26835215

    Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

    2012-05-01

    Treacher Collins syndrome is a congenital syndrome with characteristic craniofacial malformations, which are well described in the literature. However, the presence of cervical spine dysmorphology in this syndrome has been minimally described. This study reviews cervical spine radiographs of 40 patients with Treacher Collins syndrome. In this sample, 7 of 40 patients displayed cervical spine anomalies, with 3 of these patients displaying multiple cervical spine anomalies. The patterns of spinal anomalies were variable, suggesting that the underlying genetic mutation has variable expressivity in cervical spine development as it does elsewhere in the craniofacial skeleton.

    Full Text Available A 28-year-old male presented with neck pain and dysesthesias in the right upper limb. On examination, he had a firm, well-defined midline posterior cervical mass discernible on palpation at the mid-cervical level. He had no neurological deficit. Neuroradiology revealed a variegated enhancing cervical mass is arising from C3 lamina. The mass extended into the right extradural space eroding the C3 lamina and posteriorly into the intermuscular plane. The tumor was excised totally. Histopathology of the tumor showed features of hemangiopericytoma (HPC. The patient underwent postoperative radiotherapy. Primary osseous spinal HPC are rare malignant extra-axial tumors that tend to recur and metastasize. Only two cases of primary osseous HPC have been reported earlier to involve the cervical spine.

  12. What you need to know about ossification of the posterior longitudinal ligament to optimize cervical spine surgery: A review.

    What are the risks, benefits, alternatives, and pitfalls for operating on cervical ossification of the posterior longitudinal ligament (OPLL)? To successfully diagnose OPLL, it is important to obtain Magnetic Resonance Images (MR). These studies, particularly the T2 weighted images, provide the best soft-tissue documentation of cord/root compression and intrinsic cord abnormalities (e.g. edema vs. myelomalacia) on sagittal, axial, and coronal views. Obtaining Computed Tomographic (CT) scans is also critical as they best demonstrate early OPLL, or hypertrophied posterior longitudinal ligament (HPLL: hypo-isodense with punctate ossification) or classic (frankly ossified) OPLL (hyperdense). Furthermore, CT scans reveal the "single layer" and "double layer" signs indicative of OPLL penetrating the dura. Documenting the full extent of OPLL with both MR and CT dictates whether anterior, posterior, or circumferential surgery is warranted. An adequate cervical lordosis allows for posterior cervical approaches (e.g. lamionplasty, laminectomy/fusion), which may facilitate addressing multiple levels while avoiding the risks of anterior procedures. However, without lordosis and with significant kyphosis, anterior surgery may be indicated. Rarely, this requires single/multilevel anterior cervical diskectomy/fusion (ACDF), as this approach typically fails to address retrovertebral OPLL; single or multilevel corpectomies are usually warranted. In short, successful OPLL surgery relies on careful patient selection (e.g. assess comorbidities), accurate MR/CT documentation of OPLL, and limiting the pros, cons, and complications of these complex procedures by choosing the optimal surgical approach. Performing OPLL surgery requires stringent anesthetic (awake intubation/positioning) and also the following intraoperative monitoring protocols: Somatosensory evoked potentials (SSEP), motor evoked potentials (MEP), and electromyography (EMG).

    Objective To investigate incidence,diagnosis and treatment strategy of delayed esophageal complications after anterior cervical spine surgery.Methods The clinical data of 2316 patients who had undergone anterior cervical spine surgery from January 2001 to December 2011 were analyzed.The delayed esophageal complications were defined as esophageal perforation,esophago-tracheal fistula,esophago-cutaneous fistula,diverticulum of esophagus,esophagopleural fistula and esophageal stenosis that occurred 2 weeks after spine surgery.Results Delayed esophageal complications occurred in 4 patients,and the incidence was 0.17%.Esophageal perforation occurred in 2 patients; the incidence was 0.09%.Case 1 was a 31-year-old man who was found to have esophageal diverticulum and perforation 7 years after anterior cervical spine surgery.Then he underwent removal of implant,excision of diverticulum,and repair of esophagus with sternohyoid muscle flap and omohyoid muscle flap.Case 2 was a 46-year-old man who was found to have esophageal diverticulum 3 years after cervical spine surgery.He also underwent removal of implant,excision of diverticulum,and repair of esophagus with sternohyoid muscle flap and omohyoid muscle flap.Case 3 was a 58-year-old woman who was found to have esophageal diverticulum 5 years after cervical spine surgery.She underwent removal of implant,excision of diverticulum,and repair of esophagus with sternocleidomastoid muscle flap.Case 4 was a 56-year-old woman who was found to have esophageal perforation 3 years after cervical spine surgery.She underwent removal of implant and repair of esophagus with sternocleidomastoid muscle flap.All 4 patients recovered after operation.Conclusion The incidence of delayed esophageal complications after anterior cervical spine surgery is low,and the diagnosis is difficult.X-ray,digestive tract radiography,and gastrointestinal endoscopy are the main diagnostic tools.Surgical treatment is the main and effective management

  15. Sport injuries of the cervical spine

    International Nuclear Information System (INIS)

    The article reports on injuries of the cervical spine occurring during sports activities. An attempt is made to reconstruct the movements which led to the cervical spine injuries in question. In two cases of accidents occuring during bathing, one football accident and a toboggan accident, the injuries concerned point to hyperextension of the cervical spine as cause of the injury. In another football accident and a riding accident, the changes observed allow us to conclude that the movement leading to the injury must have been a hyperflexion. One accident occurring while jumping on the trampolin resulted in an injury of the upper cervical spine pointing to the action of a compressive force on the cervical spine in addition to the force resulting in hyperflexion.

    A 48-year-old man presented to the emergency department with complain of severe neck pain and anterior chest pain. Intermittent fever in the recent 2 days was also noted. There is a track maker over his left side of neck. The laboratory examination showed leukocytosis and high C-reactive protein level. Urine drug screen was positive for opiate. Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment. PMID:26298050

    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.

    We investigated the effect of preoperative patient demographics and operative factors on mortality in the 30day postoperative period after spine surgery. Postoperative mortality from surgical interventions has significantly decreased with progressive improvement in surgical techniques and patient selection. Well-studied preoperative risk factors include age, obesity, emphysema, clotting disorders, renal failure, and cardiovascular disease. However, the prognostic implications of such risk factors after spine surgery specifically remain unknown. The medical records of all consecutive patients undergoing spine surgery from 2008-2010 at our institution were reviewed. Patient demographics, comorbidities, indication for operation, surgical details, postoperative complications, and mortalities were collected. The association between preoperative demographics or surgical details and postoperative mortality was assessed via logistic regression analysis. All 1344 consecutive patients (1153 elective, 191 emergency) met inclusion criteria for the study; 19 (1.4%) patients died in the 30days following surgery. Multivariable logistic regression found several predictive factors of mortality for all spine surgery patients: operation in the cervical area (odds ratio [OR]: 7.279, 95% confidence interval [CI]: 1.37-42.83, p=0.02), postoperative sepsis (OR: 5.75, 95% CI: 1.16-26.38, p=0.03), operation for neoplastic (OR: 7.68, 95% CI: 1.53-42.71, p=0.01) or traumatic (OR: 13.76, 95% CI: 2.40-88.68, p=0.03) etiology, and age as defined as a continuous variable (OR: 1.05, 95% CI: 1.01-1.10, p=0.03). This study demonstrates predictive factors to help identify and evaluate patients who are at higher risk for mortality from spinal surgery, and potentially devise methods to reduce this risk.

    Full Text Available Cervical kyphosis in diastrophic dysplasia (DTD is a very dangerous deformity which may lead to compression of neural structures resulting in tetraplegia or even. Treatment of this deformity is usually surgical, but no long-term follow-up studies are presented in the literature. Authors present a case of two children with DTD who underwent anterior corpectomy due to severe cervical kyphosis. The kyphotic deformity was corrected and the normal spinal canal width was restored. The effects of the correction remained stable for respectively 6 and 10 years of the follow-up period. The unique follow-up confirms that this type of intervention leads to an effective and long lasting results. Significant cervical kyphosis in patients suffering from DTD may be treated surgically using anterior approach even in young children with a favorable and lasting results.

  8. Cervical spine injury in child abuse: report of two cases

    International Nuclear Information System (INIS)

    Pediatric cervical spine injuries have rarely been reported in the setting of child abuse. We report two cases of unsuspected lower cervical spine fracture-dislocation in twin infant girls who had no physical examination findings to suggest cervical spine injury. Classic radio-graphic findings of child abuse were noted at multiple other sites in the axial and appendicular skeleton. Magnetic resonance (MR) imaging proved to be valuable in both the initial evaluation of the extent of cervical spine injury and in following postoperative changes. The unexpected yet devastating findings in these two cases further substantiate the importance of routine evaluation of the cervical spine in cases of suspected child abuse. (orig.)

    Study Design Retrospective population-based observational study. Objective To assess the growth of cervical spine surgery performed in an outpatient setting. Methods A retrospective study was conducted using the United States Healthcare Cost and Utilization Project's State Inpatient and Ambulatory Surgery Databases for California, New York, Florida, and Maryland from 2005 to 2009. Current Procedural Terminology, fourth revision (CPT-4) and International Classification of Diseases, ninth revision Clinical Modification (ICD-9-CM) codes were used to identify operations for degenerative cervical spine diseases in adults (age > 20 years). Disposition and complication rates were examined. Results There was an increase in cervical spine surgeries performed in an ambulatory setting during the study period. Anterior cervical diskectomy and fusion accounted for 68% of outpatient procedures; posterior decompression made up 21%. Younger patients predominantly underwent anterior fusion procedures, and patients in the eighth and ninth decades of life had more posterior decompressions. Charlson comorbidity index and complication rates were substantially lower for ambulatory cases when compared with inpatients. The majority (>99%) of patients were discharged home following ambulatory surgery. Conclusions Recently, the number of cervical spine surgeries has increased in general, and more of these procedures are being performed in an ambulatory setting. The majority (>99%) of patients are discharged home but the nature of analyzing administrative data limits accurate assessment of postoperative complications and thus patient safety. This increase in outpatient cervical spine surgery necessitates further discussion of its safety.

    The surgical treatment of cervical kyphotic deformity remains challenging. As a surgical method that is safer and avoids major complications, the authors present a procedure of single-stage anterior and posterior fusion to correct cervical kyphosis using anterior interbody fusion cages without plating, as illustrated by three consecutive cases. Case 1 was a 78-year-old woman who presented with a dropped head caused by degeneration of her cervical spine. Case 2 was a 54-year-old woman with athetoid cerebral palsy. She presented with cervical myelopathy and cervical kyphosis. Case 3 was a 71-year-old woman with cervical kyphotic deformity following a laminectomy. All three patients underwent anterior release and interbody fusion with cages and posterior fusion with cervical lateral mass screw (LMS) fixation. Postoperative radiographs showed that correction of kyphosis was 39° in case 1, 43° in case 2, and 39° in case 3. In all three cases, improvement of symptoms was established without major perioperative complications, solid fusion was achieved, and no loss of correction was observed at a minimum follow-up of 61 months. We also report that preoperative total spine sagittal malalignment was improved after corrective surgery for cervical kyphosis and was maintained at the latest follow-up in all three cases. The combination of anterior fusion cages and LMS is considered a safe and effective procedure in cases of severe cervical kyphotic deformity. Preoperative total spine sagittal malalignment improved, accompanied by correction of cervical kyphosis, and was maintained at last follow-up in all three cases. PMID:26119893

  18. Laryngeal dislocation after ventral fusion of the cervical spine

    Directory of Open Access Journals (Sweden)

    Jenny Krauel

    2013-01-01

    Full Text Available We report on a 70-year-old patient who underwent ventral fusion of the cervical spine (C3/4 and C4/5 for spinal canal stenosis performed by the neurosurgery department. The patient suffered an exceedingly rare complication of the surgery - laryngeal dislocation. Had the deformed laryngeal structures been overlooked and the patient extubated as usual after surgery, reintubation would have been impossible due to the associated swelling, which might have had disastrous consequences. Leftward dislocation of the larynx became apparent post-operatively, but prior to extubation. Extubation was therefore postponed and a subsequent computed tomography (CT scan revealed entrapment of laryngeal structures within the osteosynthesis. A trial of repositioning using microlaryngoscopy performed by otolaryngology (ears, nose and throat specialists failed, making open surgical revision necessary. At surgery, the entrapped laryngeal tissue was successfully mobilised. Laryngeal oedema developed despite prompt repositioning; thus, necessitating tracheotomy and long-term ventilation. Laryngeal dislocation may be an unusual cause of post-operative neck swelling after anterior cervical spine surgery and should be considered in the differential diagnosis if surgical site haematoma and other causes have been ruled out. Imaging studies including CT of the neck may be needed before extubation to confirm the suspicion and should be promptly obtained to facilitate specific treatment.

    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.

    Fungal osteomyelitis is a rare infection that usually develops in immunocompromised patients. Additionally, involvement of the cervical spine by Candida albicans is extremely rare; only three previous cases of Candida vertebral osteomyelitis have been reported in the literature. The diagnosis may be delayed due to nonspecific radiologic findings and a slow progression. We report the CT, MRI, bone scan, and PET-CT findings in a patient who developed Candida osteomyelitis, which was initially misdiagnosed as metastasis, at the atlas and axis following treatment for nasopharyngeal cancer.

    Background A simple, safe and effective therapeutic strategy for traumatic instability of the subaxial cervical spine, as well as its prognostic assessment, is still controversial.Methods The therapeutic options for 83 patients of traumatic instability of the subaxial cervical spine, whose average age was 35 years, were determined, according to the Allen-Ferguson classification, general health and concomitant traumatic conditions, neurological function, position of compression materials, concomitant traumatic disc herniation/damage, concomitant locked-facet dislocation, the involved numbers and position, and the patients' economic conditions. An anterior, posterior or combination approach was used to decompress and reconstruct the cervical spine. No operations with an anterior-posterior-anterior approach were performed.Results The average follow-up was three years and nine months. Distraction-flexion and compression-flexion were the most frequent injury subtypes. There were 46, 28 and 9 cases of anterior, posterior and combination operations, respectively. The average score of the Japanese Orthopaedics Association, visual analog scale and American Spinal Cord Injury Association (ASIA) motor index improved from 11.2, 7.8 and 53.5, respectively, before operation, to 15.3, 2.6 and 67.8, respectively, at final follow-up. For incomplete spinal cord injury (SCI), the average ASIA neurological function scale was improved by 1-2 levels. Patients with complete SCI had no neurological recovery, but recovery of nerve root function occurred to different extents. After surgery, radiological parameters improved to different extents. Fusion was achieved in all patients and 12 developed complications.Conclusions The best surgical strategy should be determined by the type of subaxial cervical injury, patients' general health, local pathological anatomy and neurological function.

    Full Text Available These days, as a consequence of the improvement in technology and increase in the use of motor vehicles, spine injuries have become common. Spine traumas, which often occur after motor vehicle accidents, are observed mostly in cervical regions, particularly in the subaxial cervical region, which is also known as the subcervical region, and neurological damage occurs in 70% of the patients. Despite still being controversial, the common ranging for neurological evaluation is the American Spinal Injury Association ranging, which includes the motor and sensory loss and accordingly, the impairment rate. In subaxial cervical traumas, acute neurological deterioration is an indication and therefore requires urgent surgical treatment. The choice of anterior or posterior approach substantially depends on the traumatization mechanism, affected tissues, and neurological deterioration occurring after. The state of patient and instability are the most two important factors affecting the treatment decision. Although the anterior approach is accepted as a routinely available and easily applicable surgical technique, it lacks in the burst fractures involving the three colons, which shows a stabilization disorder. The anterior plate screw technique and posterior lateral mass screw application applied in our clinic are reviewed in literature and are discussed in two cases. Although the best clinical results are achieved in cases where only anterior surgery is performed and in cases where instability is excessive, in unstable compression and blow-out fractures, even if neurological deficit and three colon involvement are not observed in the patient, the requirement of posterior fusion is observed.

Methods A retrospective analysis was performed on 416 cases treated with anterior cervical surgery from June 2006 to August 2011. Results In these cases 29 postoperative complications associated with surgery were found, with an incidence of 6.97%,of which 6 cases were throat pain, 4 cases were aggravated spinal cord injuries,5 cases were laryngeal, recurrent laryngeal nerve injuries,2 cases were esophageal fistula,2 cases were cerebrospinal fluid leakage,2 cases were saliva leakage,3 cases were respiratory tract block,4 cases were complications in the vessels area that supply the iliac bone. One patient with respiratory tract block and one patient cerebrospinal fluid leakage died,but then the rest were recovered gradually. Conclusion Various early postoperative complications may occur in the anterior cervical spine surgery. Adequate preoperative preparation, thorough understanding of anatomy related to the anterior approach,skilled surgical technique and perfect postoperative management may prevent the complications in anterior cervical spine surgery.

    Criteria for return to sports and athletic activities after cervical spine surgery are unclear. There is limited literature regarding the outcomes and optimal criteria. Determining return to play criteria remains a challenge and continues to depend on the experience and good judgment of the treating surgeon. There is strong consensus in the literature, despite lack of evidence-based data, that athletes after single-level anterior cervical discectomy and fusion (ACDF) may safely return to collision and high-velocity sports. The athlete should be counseled and managed on a case-by-case basis, taking into consideration the type of sport, player-specific variables, and type of surgery performed. PMID:27543397

    Visualization of the lower cervical spine with a lateral radiograph poses a challenge secondary to encroachment of the shoulders. Applying traction to the arms or taping the shoulders down provides adequate visualization in most patients, but imaging the mid- to lower cervical levels presents a significant challenge in patients with stout necks. We present a variation of the lateral radiograph that is 30º oblique from horizontal and 30º cephalad from neutral and used in a series of patients with stout necks that require anterior instrumentation of the lower cervical spine. We reviewed intraoperative images of 2 patients who underwent anterior cervical spine surgery at our institution, and assessed type of procedure, body mass index, and outcome scores. Our variation provided improved visualization relative to a lateral view and was used intraoperatively to confirm correct-level hardware placement in both patients. PMID:26866322

    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 Aims and Objectives: The alignment of upper and lower cervical spine is presumed to be closely interrelated and the knowledge of this is mandatory when performing occipito-cervical and upper cervical fusions. The aim of this study was to establish standard values for upper and lower cervical spine alignment in the Indian population. Materials and Methods: Five hundred eighteen asymptomatic volunteers (261 males and 257 females between 12 and 80 years of age underwent lateral radiography with their neck in the neutral position. Angles for occipital to 2nd cervical (Oc-C2, 1st to 2nd cervical (C1-C2 and sagittal alignment of 2nd to 7th cervical vertebrae (C2-C7 were measured. Statistical analyses were performed using a statistical package SPSS 10 for windows and the students ′t′ test. Results: The mean Oc-C2, C1-C2 and C2--C7 angles were 14.66 + 9.5°, 25.6 + 7.9° and 16.8 + 12.7° in male, while same angles in female were 15.59 + 8.26°, 26.9 + 6.8° and 9.11 + 10.4° respectively. Weak statistically significant negative correlation was observed between the measured angles of the upper (Oc-C2 and C1-C2 and lower (C2-C7 cervical spines, which means if the lordosis of the occiput and upper cervical spine increases (if the Oc-C2 angle increases, the alignment of lower cervical spine becomes kyphotic and vice versa. This negative correlation was stronger between the Oc-C2 and C2-C7 angles than between the C1-C2 and C2-C7 angles. Conclusions: Relationship between alignment of the upper and the lower cervical spine should be taken into consideration when performing cervical fusion.

    Full Text Available Animals are commonly used to model the human spine for in vitro and in vivo experiments. Many studies have investigated similarities and differences between animals and humans in the lumbar and thoracic vertebrae. However, a quantitative anatomic comparison of calf, pig, and human cervical spines has not been reported.To compare fundamental structural similarities and differences in vertebral bodies from the cervical spines of commonly used experimental animal models and humans.Anatomical morphometric analysis was performed on cervical vertebra specimens harvested from humans and two common large animals (i.e., calves and pigs.Multiple morphometric parameters were directly measured from cervical spine specimens of twelve pigs, twelve calves and twelve human adult cadavers. The following anatomical parameters were measured: vertebral body width (VBW, vertebral body depth (VBD, vertebral body height (VBH, spinal canal width (SCW, spinal canal depth (SCD, pedicle width (PW, pedicle depth (PD, pedicle inclination (PI, dens width (DW, dens depth (DD, total vertebral width (TVW, and total vertebral depth (TVD.The atlantoaxial (C1-2 joint in pigs is similar to that in humans and could serve as a human substitute. The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4-C6. The width and depth of the calf odontoid process were larger than those in humans. VBW and VBD of calf cervical vertebrae were larger than those in humans, but the spinal canal was smaller. Calf C7 was relatively similar to human C7, thus, it may be a good substitute.Pig cervical vertebrae were more suitable human substitutions than calf cervical vertebrae, especially with respect to C1, C2, and C7. The biomechanical properties of nerve vascular anatomy and various segment functions in pig and calf cervical vertebrae must be considered when selecting an animal model for research on the spine.

  1. Cervical spine injuries in the pediatric and adolescent athlete.

    Science.gov (United States)

    Herman, Martin J

    2006-01-01

    Injuries of the cervical spine in the pediatric and adolescent athlete are less common than other musculoskeletal injuries. Although many of these injuries are relatively minor, serious and potentially unstable or progressive spinal injury must be excluded. Important anatomic differences between the child younger than 10 years and older children and adolescents influence the types of injuries sustained and make assessment of the child's cervical spine sometimes difficult for practitioners accustomed to treating adolescent and adult athletes. Stable soft-tissue injuries of the cervical spine are the most common injuries that occur in all athletes. These injuries are responsive to symptomatic treatment and aggressive rehabilitation. Stingers are injuries of the brachial plexus and upper cervical roots that result from stretching or compressive forces associated with collision sports. Rapid return of sensory and motor dysfunction of a single upper extremity characterizes this entity; long-term disability is rare. Cervical cord neurapraxia (CCN) with transient quadriplegia is most commonly seen in football players. Most athletes fully recover. Cervical canal stenosis as defined by a Pavlov/Torg ratio of less than or equal to 0.8 is predictive of recurrent CCN. Young athletes sustain CCN secondary to hypermobility of the immature cervical spine. Return to play after these injuries is controversial. The athlete with Down syndrome and potential cervical hypermobility requires a careful cervical and neurologic evaluation prior to clearance for participation in sports. PMID:16958497

    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.

A review of 6,774 consecutive cervical spine multidetector CT (MDCT) scans obtained during 6.2 years revealed 33 ankylosed spines studied for suspected acute cervical spine injury complicating AS. Of these, 20 patients also underwent MRI. On MRI, of these 20 patients, 19 had a total of 29 cervical and upper thoracic spine fractures. Of 20 transverse fractures traversing both anterior and posterior columns, 7 were transdiskal and exhibited less bone marrow edema than did those traversing vertebral bodies. One Jefferson's, 1 atlas posterior arch (Jefferson's on MDCT), 2 odontoid process, and 5 non-contiguous spinous process fractures were detectable. MRI showed 2 fractures that were undetected by MDCT, and conversely, MDCT detected 6 fractures not seen on MRI; 16 patients had spinal cord findings ranging from impingement and contusion to complete transection. Magnetic resonance imaging can visualize unstable fractures of the cervical and upper thoracic spine. Paravertebral hemorrhages and any ligamentous injuries should alert radiologists to seek transverse fractures. Multiple fractures are common and often complicated by spinal cord injuries. Diagnostic images can be obtained with a flexible multipurpose coil if the use of standard spine array coil is impossible due to a rigid collar or excessive kyphosis. (orig.)

    Full Text Available Gout is clinically characterized by episodes of monoarthritis, but if not treated properly, it can lead to a chronic polyarthritis, which may eventually mimic rheumatoid arthritis (RA. We present the case of a 59-year-old man, with a history of symmetrical polyarthritis of the large and small joints with later development of subcutaneous nodules, which was initially misdiagnosed as RA, being treated with prednisone and methotrexate for a long period of time. He complained of occipital pain and paresthesia in his left upper limb, and computed tomography (CT and magnetic resonance imaging (MRI revealed the presence of an expansive formation in the cervical spine with compression of the medulla. He was admitted for spinal decompressive surgery and the biopsy specimen demonstrated a gouty tophus. Chronic gout can mimic RA and rarely involves the axial skeleton, and thus its correct diagnosis and the implementation of adequate therapy can halt the development of such damaging complications.

    We present the case of a 44-year-old man who complained of cervical pain. He was treated with physiotherapy and analgetics. Because of persistent pain, computed tomography (CT) scan and MRI were performed. They revealed an osteolytic destruction of the fourth cervical vertebra. The patient was treated surgically for removal of the tumor and stabilization of his cervical spine. Histology of the osteolytic material led to the diagnosis of an eosinophilic granuloma of the cervical spine. This case report describes the incidence, clinical significance, background and therapy of an eosinophilic granuloma of the spine. PMID:15120180

    2001-10-01

    Full Text Available The anterior retropharyngeal approach (ARPA accesses anteriorly situated lesions from the clivus to C3, in patients with a short neck, Klippel Feil anomaly or those in whom the C2-3 and C3-4 disc spaces are situated higher in relation to the hyoid bone and the angle of mandible where it is difficult to approach this region using the conventional anterior approach, due to the superomedial obliquity of the trajectory. The ARPA avoids the potentially contaminated oropharyngeal cavity providing for a simultaneous arthrodesis and instrumentation during the primary surgical procedure. Experience of five patients with high cervical extradural compression, who underwent surgery using this approach between 1994 and 1999, is presented. The surgical procedures included excision of ossified posterior longitudinal ligament (n=2; excision of prolapsed disc and osteophytes (n=2; and excision of a vertebral body neoplasm (n=1. Following the procedure, vertebral arthrodesis was achieved using an iliac graft in all the patients. Only one patient with vertebral body neoplasm required an additional anterior cervical plating procedure for stabilisation the construct. The complications included transient respiratory insufficiency and neurological deterioration in two patients; and, pharyngeal fistula and donor site infection in one patient.

  11. The rheumatoid cervical spine: Signs of instability on plain cervical radiographs

    Energy Technology Data Exchange (ETDEWEB)

    Roche, Clare J.; Eyes, Brian E.; Whitehouse, Graham H

    2002-04-01

    The cervical spine is a common focus of destruction from rheumatoid arthritis, second only to the metacarpophalangeal joints. Joint, bone and ligament damage in the cervical spine leads to subluxations which can cause cervical cord compression resulting in paralysis and even sudden death. Because many patients with significant subluxations are asymptomatic, the radiologist plays a key role in recognizing the clinically important clues to instability on plain radiographs of the cervical spine-often difficult in rheumatoid arthritis when the bony landmarks are osteoporotic or eroded. This review focuses on the signs of instability on plain radiographs of the cervical spine, using diagrams and clinical examples to illustrate methods of identifying significant subluxations in rheumatoid arthritis.

    Lehman, Ronald A; Kang, Daniel Gene; Wagner, Scott Cameron

    2015-04-01

    Osteoporosis is a burgeoning clinical problem that is characterized by decreased bone strength and density. It predisposes patients to fragility fractures and debilitating spine deformities. Several complications are associated with spine surgery in patients with osteoporosis, and there is currently no treatment algorithm to guide the spine surgeon. A multidisciplinary approach to treatment of patients with osteoporosis and spine deformity or fracture is encouraged, and preoperative planning is crucial for successful surgical outcomes. Several surgical techniques have been developed to treat osteoporosis-related deformities, including posterior instrumentation with fusion. However, achieving fixation and fusion in these patients can be difficult secondary to poor bone stock. Augmentation methods to improve pedicle screw fixation have evolved, including instrumentation at multiple levels, bioactive cement augmentation, and fenestrated or expandable pedicle screws, but their impact on clinical outcomes remains unknown. Management of osteoporosis in patients undergoing spine surgery is challenging, but with appropriate patient selection, medical optimization, and surgical techniques, these patients can experience pain relief, deformity correction, and improved function.

    2007-07-01

    The goal of the present study was to determine the dynamic sagittal flexibility coefficients, including coupling coefficients, throughout the human cervical spine using rear impacts. A biofidelic whole cervical spine model (n=6) with muscle force replication and surrogate head was rear impacted at 5 g peak horizontal accelerations of the T1 vertebra within a bench-top mini-sled. The dynamic main and coupling sagittal flexibility coefficients were calculated at each spinal level, head/C1 to C7/T1. The average flexibility coefficients were statistically compared (p<0.05) throughout the cervical spine. To validate the coefficients, the average computed displacement peaks, obtained using the average flexibility matrices and the measured load vectors, were statistically compared to the measured displacement peaks. The computed and measured displacement peaks showed good overall agreement, thus validating the computed flexibility coefficients. These peaks could not be statistically differentiated, with the exception of extension rotation at head/C1 and posterior shear translation at C7/T1. Head/C1 was significantly more flexible than all other spinal levels. The cervical spine was generally more flexible in posterior shear, as compared to axial compression. The coupling coefficients indicated that extension moment caused coupled posterior shear translation while posterior shear force caused coupled extension rotation. The present results may be used towards the designs of anthropometric test dummies and mathematical models that better simulate the cervical spine response during dynamic loading. PMID:17140545

    35 healthy adults and 137 patients after cervical spine injury were examined by functional CT. The range of axial rotation at the level occiput/atlas, atlas/axis and the segment below were measured in all subjects. A rotation occiput/atlas of more than 7/sup 0/, and C1/C2 more than 54/sup 0/ could refer to segmental hypermobility, a rotation at the segment C1/C2 less than 29/sup 0/ to hypomobility. According to the postulated normal values based upon a 98% confidence level, out of 137 patients examined after cervical spine injury and with therapy-resistant neck pain, 45 showed signs of segmental hypermobility of the upper cervical spine, 17 showed hyper- or hypomobility at different levels, 10 patients presented segmental hypomobility at C1/C2 level alone. In all patients, according to the clinical assessment, functional pathology was suspected in the upper cervical spine. Surgical correction of rotatory instability should be considered as a possible therapeutic procedure after successful diagnostic stabilisation of the cervical spine by minerva cast.

    2016-01-01

    Background. There is a lack of scientific evidence in the literature on the involvement of the cervical spine in mTBI; however, its involvement is clinically accepted. Objective. This paper reviews evidence for the involvement of the cervical spine in mTBI symptoms, the mechanisms of injury, and the efficacy of therapy for cervical spine with concussion-related symptoms. Methods. A keyword search was conducted on PubMed, ICL, SportDiscus, PEDro, CINAHL, and Cochrane Library databases for articles published since 1990. The reference lists of articles meeting the criteria (original data articles, literature reviews, and clinical guidelines) were also searched in the same databases. Results. 4,854 records were screened and 43 articles were retained. Those articles were used to describe different subjects such as mTBI's signs and symptoms, mechanisms of injury, and treatments of the cervical spine. Conclusions. The hypothesis of cervical spine involvement in post-mTBI symptoms and in PCS (postconcussion syndrome) is supported by increasing evidence and is widely accepted clinically. For the management and treatment of mTBIs, few articles were available in the literature, and relevant studies showed interesting results about manual therapy and exercises as efficient tools for health care practitioners.

  18. Cervical spine trauma: Radiologic manifestations and imaging algorithms

    International Nuclear Information System (INIS)

    Cervical spine trauma is very critical injury that is incurred most frequently in automobile accidents, mining incidents, and war. Injuries of the cervical spine produce neurologic damage in approximately 40% of cases, whereas injuries of the thoracolumbar junction produce neurologic damage in 4% and injuries of the thoracic spine do so in 10%. Radiology has a fundamental role in the recognition and follow-up of patients. Radiologists should be quite familiar with the imaging algorithms and various radiologic manifestations of cervical spine injuries. In this paper, techniques of examining severely injured patients as well as those with slight or questionable injuries are demonstrated. Indications and limitations of various diagnostic procedures (plain film radiography, tomography, CT, and MR imaging) are discussed. A systematic plan for the study of the cervical spine with an emphasis on joints, bones, ligaments and soft tissues (JO-B-LI-ST) is introduced. Mechanisms of injury and the stability or instability of the injuries are presented. Plain radiography as well as other imaging modalities are used to demonstrate the most important forms of injuries at various levels. Follow-up of some of the treated cases is shown. The late complications of spinal cord damage in closed injuries and open wounds (urinary stones, myositis, ossificans, contractures, fractures, disuse atrophy, and bone infections) are presented at the end

    2004-07-01

    Objective: The objective of this study was to evaluate the diagnostic value of prevertebral soft tissue swelling in cervical spine injuries. Materials and methods: A group of 107 consecutive patients with suspected injuries of the cervical vertebrae were reviewed retrospectively to identify the presence of prevertebral soft tissue swelling and to investigate the association of prevertebral soft tissue swelling with the types and degrees of cervical spine injuries. Results: Prevertebral soft tissue swelling occurred in 47 (43.9%) patients. Of the 47 patients, 38 were found with bony injury and nine were without. The statistic difference was significant (P<0.05). No correlation was demonstrated between soft tissue swelling and either the injured level of the cervical vertebrae or the degree of the spinal cord injury (P>0.05). Anterior element injuries in the cervical vertebrae had widening of the prevertebral soft tissue more than posterior element injuries (P<0.05). Conclusion: The diagnostic value of prevertebral soft tissue swelling for cervical spine injuries is significant, but the absence of this sign does not mean that further image evaluation can be spared.

    Study Design Interobserver and intraobserver reliability study. Objective The aim of this study is to validate a new classification system of external cervical spine immobilization devices by measuring the interobserver and intraobserver agreement. Methods A classification system, with five main categories, based on the anatomical regions on which the device supports, was created. A total of 28 independent observers classified 50 photographs of different devices, designed to immobilize the cervical spine according to the new proposed classification system. At least 2 weeks later, the same devices were classified again in a new random order. Before and after the classification, all the participants answered questions about the usefulness of the proposed classification. Results The mean interobserver and intraobserver agreement Fleiss' kappa was 0.88 and 0.91, respectively. Both are, according to the interpretation described by Landis and Koch, "almost perfect." A majority of the participators answered that they needed a classification (89%) and considered the classification to be clear (96%). All the participants considered the classification to be useful in clinical practice. Conclusion This study showed that the new classification of external cervical spine immobilizers, based on anatomical support areas, has an excellent interobserver and intraobserver agreement. Furthermore, the study participants considered the proposed classification to be clear and useful in clinical practice. As the majority of patients with cervical spine injuries are treated with external immobilization devices, this new classification system can improve the closed treatment of cervical spine injuries in daily clinical practice. Furthermore, it makes reproducible comparisons between groups possible, which are essential for further evolution of evidence-based spine care. PMID:24436704

  5. Comparison of Three Prehospital Cervical Spine Protocols for Missed Injuries

    2014-07-01

    Full Text Available Introduction: We wanted to compare 3 existing emergency medical services (EMS immobilization protocols: the Prehospital Trauma Life Support (PHTLS, mechanism-based; the Domeier protocol (parallels the National Emergency X-Radiography Utilization Study [NEXUS] criteria; and the Hankins’ criteria (immobilization for patients 65 years, those with altered consciousness, focal neurologic deficit, distracting injury, or midline or paraspinal tenderness.To determine the proportion of patients who would require cervical immobilization per protocol and the number of missed cervical spine injuries, had each protocol been followed with 100% compliance. Methods: This was a cross-sectional study of patients ≥18 years transported by EMS post-traumatic mechanism to an inner city emergency department. Demographic and clinical/historical data obtained by physicians were recorded prior to radiologic imaging. Medical record review ascertained cervical spine injuries. Both physicians and EMS were blinded to the objective of the study. Results: Of 498 participants, 58% were male and mean age was 48 years. The following participants would have required cervical spine immobilization based on the respective protocol: PHTLS, 95.4% (95% CI: 93.1-96.9%; Domeier, 68.7% (95% CI: 64.5-72.6%; Hankins, 81.5% (95% CI: 77.9-84.7%. There were 18 cervical spine injuries: 12 vertebral fractures, 2 subluxations/dislocations and 4 spinal cord injuries. Compliance with each of the 3 protocols would have led to appropriate cervical spine immobilization of all injured patients. In practice, 2 injuries were missed when the PHTLS criteria were mis-applied. Conclusion: Although physician-determined presence of cervical spine immobilization criteria cannot be generalized to the findings obtained by EMS personnel, our findings suggest that the mechanism-based PHTLS criteria may result in unnecessary cervical spine immobilization without apparent benefit to injured patients.

    Cervical spine as a complicated part in the human body, the form of its movement is diverse. The movements of the segments of vertebrae are three-dimensional, and it is reflected in the changes of the angle between two joint and the displacement in different directions. Under normal conditions, cervical can flex, extend, lateral flex and rotate. For there is no relative motion between measuring marks fixed on one segment of cervical vertebra, the cervical vertebrae with three marked points can be seen as a body. Body's motion in space can be decomposed into translational movement and rotational movement around a base point .This study concerns the calculation of dimensional coordinate of the marked points pasted to the human body's cervical spine by an optical method. Afterward, these measures will allow the calculation of motion parameters for every spine segment. For this study, we choose a three-dimensional measurement method based on binocular stereo vision. The object with marked points is placed in front of the CCD camera. Through each shot, we will get there two parallax images taken from different cameras. According to the principle of binocular vision we can be realized three-dimensional measurements. Cameras are erected parallelly. This paper describes the layout of experimental system and a mathematical model to get the coordinates.

    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.

    Surgical site infection (SSI) after spinal deformity surgery is a complication in the pediatric population resulting in high morbidity and cost. Despite modern surgical techniques and preventative strategies, the incidence remains substantial, especially in the neuromuscular population. This review focuses on recent advancements in identification of risk factors, prevention, diagnosis, and treatment strategies for acute and delayed pediatric spine infections. It reviews recent literature, including the best practice guidelines for infection prevention in high-risk patients. Targets of additional research are highlighted to assess efficacy of current practices to further reduce risk of SSI in pediatric patients with spinal deformity. PMID:26772947

    Full Text Available Background: Cervical pedicle screw fixation is challenging due to the small osseous morphometrics and the close proximity of neurovascular elements. Computer navigation has been reported to improve the accuracy of pedicle screw placement. There are very few studies assessing its efficacy in the presence of deformity. Also cervical pedicle screw insertion in children has not been described before. We evaluated the safety and accuracy of Iso-C 3D-navigated pedicle screws in the deformed cervical spine. Materials and Methods: Thirty-three patients including 15 children formed the study group. One hundred and forty-five cervical pedicle screws were inserted using Iso-C 3D-based computer navigation in patients undergoing cervical spine stabilization for craniovertebral junction anomalies, cervico-thoracic deformities and cervical instabilities due to trauma, post-surgery and degenerative disorders. The accuracy and containment of screw placement was assessed from postoperative computerized tomography scans. Results: One hundred and thirty (89.7% screws were well contained inside the pedicles. Nine (6.1% Type A and six (4.2% Type B pedicle breaches were observed. In 136 levels, the screws were inserted in the classical description of pedicle screw application and in nine deformed vertebra, the screws were inserted in a non-classical fashion, taking purchase of the best bone stock. None of them had a critical breach. No patient had any neurovascular complications. Conclusion: Iso-C navigation improves the safety and accuracy of pedicle screw insertion and is not only successful in achieving secure pedicle fixation but also in identifying the best available bone stock for three-column bone fixation in altered anatomy. The advantages conferred by cervical pedicle screws can be extended to the pediatric population also.

    Spinal involvement is a common presentation of multiple myeloma (MM); however, the cervical spine is the least common site of myelomatous involvement. Few studies evaluate the results of percutaneous vertebroplasty (PV) in the treatment of MM of the spine. The purpose of this series is to report on the use of PV in the treatment of MM of the cervical spine and to review the literature. From January 1994 to October 2007, four patients (three men and one woman; mean age, 45 years) who underwent five PV for painful MM in the cervical spine were retrospectively reviewed. The pain was estimated by the patient on a verbal analogic scale. Clinical follow-up was available for all patients (mean, 27.5 months; range, 1-96 months). The mean volume of cement injected per vertebral body was 2.3 {+-} 0.8 mL (range, 1.0-4.0 mL) with a mean vertebral filling of 55.0 {+-} 12.0% (range, 40.0-75.0%). Analgesic efficacy was achieved in all patients. One patient had a spinal instability due to a progression of spinal deformity noted on follow-up radiographs, without clinical symptoms. Cement leakage was detected in three (60%) of the five treated vertebrae. There was no clinical complication. The present series suggests that PV for MM of the cervical spine is safe and effective for pain control; nonetheless, the detrimental impact of the disease on bone quality should prompt close radiological follow-up after PV owing to the risk of spinal instability.

    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. PMID:27408495

    Full Text Available OBJECTIVE: To evaluate the complications of anterior approach to the cervical spine in patients who underwent cervical arthrodesis with instrumentation. METHODS: Prospective and descriptive study was conducted from January 2009 to April 2010. All patients who underwent arthrodesis of the cervical spine by anterior approach were included, regardless the diagnosis. Access was made by the anterior approach on the right side. We evaluated the number of operated levels (1, 2 or 3 levels and, the type of procedure performed: discectomy and placement of cage and plate (D+C+P, discectomy with placement of a cage (D+C or corpectomy with placement of cage and plate (C+C+P. All complications related to surgical approach were reported. RESULTS: We studied 34 patients, 70% male. The average age was 50 years and mean follow-up was 8 months. Eighteen percent of patients had complications, distributed as follows: dysphasia (33% and dysphonic (67%. Among patients who developed complications, most underwent to D+C+P (83% and no complications were found in patients where no cervical plate was used. Regarding levels, both complications were identified in patients operated to one or two levels. However, in patients operated on three levels, only dysphonia was identified. CONCLUSION: The most frequent complication was dysphonia. Patients who presented more complications were those undergoing discectomy and fusion with cage and anterior cervical plate. All cases of dysphonia were in this group. The number of accessible levels does not seem to have affected the incidence of complications.

    The cervical spine may be specifically involved in crystal-associated arthropathies. In this article, we focus on the three common crystals and diseases: hydroxyapatite crystal deposition disease, calcium pyrophosphate dihydrate (CPPD) deposition disease, and monosodium urate crystals (gout). The cervical involvement in crystal-associated diseases may provoke a misleading clinical presentation with acute neck pain, fever, or neurological symptoms. Imaging allows an accurate diagnosis in typical cases with calcific deposits and destructive lesions of the discs and joints. Most of the cases are related to CPPD or hydroxyapatite crystal deposition; gout is much less common. (orig.)

  1. Surgical treatment for ossification of the posterior longitudinal ligament in the cervical spine.

    2014-07-01

    Although classically associated with patients of East Asian origin, ossification of the posterior longitudinal ligament (OPLL) may cause myelopathy in patients of any ethnic origin. Degeneration of the PLL is followed by endochondral ossification, resulting in spinal cord compression. Specific genetic polymorphisms and medical comorbidities have been implicated in the development of OPLL. Patients should be evaluated with a full history and neurologic examination, along with cervical radiographs. Advanced imaging with CT and MRI allows three-dimensional evaluation of OPLL. Minimally symptomatic patients can be treated nonsurgically, but patients with myelopathy or severe stenosis are best treated with surgical decompression. OPLL can be treated via an anterior (ie, corpectomy and fusion) or posterior (ie, laminectomy and fusion or laminoplasty) approach, or both. The optimal approach is dictated by the classification and extent of OPLL, cervical spine sagittal alignment, severity of stenosis, and history of previous surgery. Anterior surgery is associated with superior outcomes when OPLL occupies >50% to 60% of the canal, despite increased technical difficulty and higher complication rates. Posterior surgery is technically easier and allows decompression of the entire cervical spine, but patients may experience late deterioration because of disease progression. PMID:24966248

    Full Text Available Analysis of the Functional Independence Measure Value of Cervical Spine Injury Patients with Conservative Management. Cervical spine injury is one of the most common spinal cord injuries in trauma patients. From 100,000 spinal cord injury cases reported in the United States of America (2008, sixty seven percent involve cervical spine injury. American Spinal Cord Injury Association (ASIA impairment score is used as an initial assessment but not enough attention prognostic outcome of these patients was paid to. The objective of this study is to analyze the value of functional independence measure (FIM cervical spine injury patients with conservative management and its correlation with age, sex, type of trauma, onset of trauma, cervical abnormalities, type of cervical spine lesion and ASIA impairment score. A prospective cohort study was performed to all patients with cervical spine injury treated inNeurosurgery Department of Dr. Hasan Sadikin Hospital Bandung that fullfiled the inclusion criteria. The subjects were classified based on age, sex, single/multiple trauma, acute /chronic, cervical abnormalities, complete/incomplete lesion and ASIA impairment score. The FIM examination was performed in Outpatient clinic of Neurosurgery. T-test and chi-square test was done to analyze the data. There were 17 cervical spine injury patients treated in Neurosurgery Department of Dr. Hasan Sadikin Hospital during April 2009–April 2010. The average FIM value of cervical spine injury in those patients is 4+ 1.63 by cohort prospective study. There were no correlation between FIM value with age, sex, type of trauma, onset of trauma and cervical abnormalities. Significant correlations were found between FIM value with type of cervical spine lesion and ASIA impairment score in cervical spine patients. Type of cervical spine lesion and ASIA impairment score have significant correlation with FIM value of patients in 6 months after cervical injury.

  3. Magnetic resonance tomography for trauma of the cervical spine

    International Nuclear Information System (INIS)

    Twenty patients who had suffered spinal trauma were examined by magnetic resonance tomography. Fifteen patients with first degree trauma in Erdmann's classification showed no abnormality. Magnetic resonance tomography of the cervical spine appears to be a suitable method for investigating patients with whiplash injuries. It is indicated following severe flexion injuries with subluxations and neurological symptoms, since it is the only method that can demonstrate the spinal cord directly and completely and show the extent of cord compression. For patients with thoracic trauma and rapidly developing neurological symptoms, magnetic resonance tomography is ideal for showing post-traumatic syringomyelia. Magnetic resonance tomography following whiplash injuries is recommended if plain films of the cervical spine show any abnormalities, as well as for the investigation of acute or sub-acute neurological abnormalities. The various findings are discussed. (orig.)

    Purpose: To analyze multidetector computed tomography (MDCT) cervical spine findings in trauma patients with advanced ankylosing spondylitis (AS). Material and Methods: Using PACS, 2282 cervical spine MDCT examinations requested by emergency room physicians were found during a period of 3 years. Of these patients, 18 (16 M, aged 41-87, mean 57 years) had advanced AS. Primary imaging included radiography in 12 and MRI in 11 patients. Results: MDCT detected one facet joint subluxation and 31 fractures in 17 patients: 14 transverse fractures, 8 spinous process fractures, 2 Jefferson's fractures, 1 type I and 2 type II odontoid process fractures, and 1 each: atlanto-occipital joint fracture and C2 laminar fracture plus isolated transverse process and facet joint fractures. Radiographs detected 48% and MRI 60% of the fractures. MRI detected all transverse and odontoid fractures, demonstrating spinal cord abnormalities in 72%. Conclusion: MDCT is superior to plain radiographs or MRI, showing significantly more injuries and yielding more information on fracture morphology. MRI is valuable, however, in evaluating the spinal cord and soft-tissue injuries. Fractures in advanced AS often show an abnormal orientation and are frequently associated with spinal cord injuries. In these patients, for any suspected cervical spine injuries, MDCT is therefore the imaging modality of choice.

    1998-01-01

    A retrospective study of cervical spine injuries that occurred during the rugby scrum in the United States was undertaken. In the U.S., from 1970 to 1996, 36 (58%) of the 62 documented injured players injured their cervical spines during the scrum. Thirty-five men (97%) and one woman (3%) were injured. Twenty-three of the injuries (64%) occurred when the opposing packs came together (engagement), and 13 (36%) occurred when the scrum collapsed. Twenty-eight (78%) hookers, seven (19%) props, and one (3%) second-row player were injured. Twenty (56%) hookers and three (8%) props were hurt during engagement. Eight hookers (22%), four props (11%), and one second-row player (3%) were injured when the scrum collapsed. Significantly more injuries occurred during engagement than during collapse, and hookers were injured significantly more than props. We conclude that in the rugby scrum in the U.S., the hooker suffers most of the cervical spine injuries (78% in this study) and this position is by far the most vulnerable. This study should be used to develop rugby law (rule) changes and educate players, coaches, and referees in United States rugby. PMID:9548109

    1. The whiplash injury of the cervical spine is a typical, but not very often observed injury of occupants of automotive vehicles involved in moderate collisions. 2. There still exist great uncertainties in the elaboration of expertises concerning the minor whiplash injury, so that the great part of the disturbances cannot be objectivated under a clinical point of view. And on the other hand, serious whiplash injuries often are superposed or veiled by secondary injuries. 3. Thus, the aim of the present paper was to point out injury mechanisms, to give a rough scaling of the whiplash severity under biomechanical aspects and finally to set these injury mechanisms in correlation to the following criteria of accident: a) vehicle velocity change (energy equivalent speed--EES); b) deformation of vehicles on the impact-exposed structure; c) loading of occupants by acceleration or deceleration. 4. The tolerance limit of the cervical spine generally decreases to a lower limit, if the cervical spine is changed in a pathological way, e.g. by preexisting diseases. 5. It is evident and important, that the difficult work of giving an expert's opinion on this field must be performed in an interdisciplinary collaboration of engineers for collision-analysis and physicians experienced in accident-traumatology.

    In analysis of the cervical and cervicobrachial syndrome with or without signs of compression of the nerve root or spinal cord, functional assessment of the cervical spine is of great importance. Comparisons between actively performed and passively induced motion can be verified by using standardized computer-assisted assessment allowing precise documentation of the range of motion and coupled motion. The age-related normal values should be considered. The neurological assessment includes not only the cranial nerves and upper extremities but also lower extremities to avoid overlooking the signs of cervical myelopathy. In patients with compression of nerve roots or the spinal cord neurophysiology might be helpful in identifying or verifying compression. In patients with suspected myelopathy sensory evoked potentials will allow assessment of the function of the ascending spinal pathways and motor evoked potentials, assessment of the function of the descending cortical spinal pathways.

    The transoral surgical approach is useful for operating on structures at the base of the brain and the upper cervical spinal cord. For example, this route has been used for resecting spinal tumors and clipping vertebrobasilar aneurysms. In the past, this surgical approach was not advocated due to concerns about exposure and infection. However, the availability of the microscope, computed tomography, computed myelotomography, magnetic resonance imaging and intraoperative radiography as well as more effective techniques have improved the diagnosis of pathology of the craniovertebral junction and surgical performance. An understanding of the operative procedures involved with this approach assists the neuro-science nurse in preoperative teaching and anticipating potential postoperative complications. PMID:1402151

  1. Narrative review of the in vivo mechanics of the cervical spine after anterior arthrodesis as revealed by dynamic biplane radiography.

    Arthrodesis is the standard of care for numerous pathologic conditions of the cervical spine and is performed over 150,000 times annually in the United States. The primary long-term concern after this surgery is adjacent segment disease (ASD), defined as new clinical symptoms adjacent to a previous fusion. The incidence of adjacent segment disease is approximately 3% per year, meaning that within 10 years of the initial surgery, approximately 25% of cervical arthrodesis patients require a second procedure to address symptomatic adjacent segment degeneration. Despite the high incidence of ASD, until recently, there was little data available to characterize in vivo adjacent segment mechanics during dynamic motion. This manuscript reviews recent advances in our knowledge of adjacent segment mechanics after cervical arthrodesis that have been facilitated by the use of dynamic biplane radiography. The primary observations from these studies are that current in vitro test paradigms often fail to replicate in vivo spine mechanics before and after arthrodesis, that intervertebral mechanics vary among cervical motion segments, and that joint arthrokinematics (i.e., the interactions between adjacent vertebrae) are superior to traditional kinematics measurements for identifying altered adjacent segment mechanics after arthrodesis. Future research challenges are identified, including improving the biofidelity of in vitro tests, determining the natural history of in vivo spine mechanics, conducting prospective longitudinal studies on adjacent segment kinematics and arthrokinematics after single and multiple-level arthrodesis, and creating subject-specific computational models to accurately estimate muscle forces and tissue loading in the spine during dynamic activities.

    Hyperintense areas of vertebral bone marrow on fluid-sensitive sequences are at times seen on pediatric MRI of the cervical spine in children without suspicious clinical conditions to explain marrow pathology. Although these likely have no clinical significance they may be mistaken for pathology. The purpose of this study is to systematically evaluate the locations and patterns of marrow T2 hyperintensity in the pediatric cervical spine, with respect to age. At 1.5 T, the C2 through T3 vertebrae of 82 children aged 0-17 years without clinically suspicious marrow abnormality were retrospectively reviewed by two musculoskeletal radiologists, who were blinded to patients' age. The frequency, intensity, and location of the foci of marrow T2 hyperintensity were recorded for each vertebra on a 12-point scoring system and were correlated with the patients' age. Foci of marrow hyperintensity were seen in 46/82 (56.1%) patients and in 241/734 (32.8%) vertebrae. Foci were most common in C4 (42% of patients), C5 (45.7%), and C6 (37.8%). The foci of T2 hyperintensity were more common inferiorly (188 foci) and adjacent to the anterior cortex (123). Analysis revealed no significant correlation between age and marrow score (Spearman = -0.147, P = 0.19), but did find a trend towards increased presence of marrow T2 hyperintensity in the ages of most rapid growth, 8-14 years (81.5% of patients). Vertebral body marrow T2 hyperintensity was most common endosteally and in the mid-cervical spine with a slight peak in adolescence. We therefore believe that these pediatric cervical marrow changes may be related to rapid bone growth at the point of maximal kyphotic stress. (orig.)

    OBJECTIVE: To compare 2 methods of determining cervical spinal stenosis (Torg ratio, space available for the cord [SAC]); determine which of the components of the Torg ratio and the SAC account for more of the variability in the measures; and present standardized SAC values for normal subjects using magnetic resonance imaging (MRI). DESIGN AND SETTING: The research design consisted of a posttest-only, comparison-group design. The independent variable was method of measurement (Torg ratio and SAC). The dependent variables were Torg ratio and SAC scores. SUBJECTS: Fourteen men (age = 24.4 +/- 2.5 years, height = 181.0 +/- 5.8 cm, weight = 90 +/- 13.5 kg) participated in this study. The C3 to C7 vertebrae were examined in each subject (n = 70). MEASUREMENTS: The Torg ratio was determined by dividing the sagittal spinal-canal diameter by the corresponding sagittal vertebral-body diameter. The SAC was determined by subtracting the sagittal spinal-cord diameter from the corresponding sagittal spinal-canal diameter. The Torg ratio and SAC were measured in millimeters. RESULTS: The SAC ranged from 2.5 to 10.4 mm and was greatest at C7 in 71% (10 of 14) of the subjects. The SAC was least at C3 or C5 in 71% (10 of 14) of the subjects. A Pearson product moment correlation revealed a significant relationship between the Torg ratio and SAC (r =.53, P SAC than the spinal cord (r (2) =.23). CONCLUSIONS: The SAC measure relies more on the spinal canal compared with the Torg ratio and, therefore, may be a more effective indicator of spinal stenosis. This is relevant clinically because neurologic injury related to stenosis is a function of the spinal canal and the spinal cord (not the vertebral body). Further research must be done, however, to validate the SAC measure. PMID:12937434

    Full Text Available Background and Aims: We have utilized lift-up laminoplasty to treat patients with myelopathy caused by ossification of the posterior longitudinal ligament (OPLL of the cervical spine. The preliminary surgical outcome with computer-assisted morphological assessment is presented. Material and Methods: The surgical technique of lift-up laminoplasty includes standard posterior exposure of the cervical spine, en-bloc laminectomy, and expansion of the cervical canal by lift-up of the laminae with custom-designed hydroxyapatite laminar spacers and stabilization of the laminae using titanium miniplates. From 1998 to 2003, 10 consecutive patients with cervical myelopathy secondary to OPLL have been treated with this method and comprehensively evaluated. Care was taken to tailor the treatment to individual patients by using different sizes of spacers to adjust the degree of expansion depending on the amount of stenosis of the cervical spine. The degree of expansion of the cervical canal was altered by design, based on the preoperative imaging simulation. Results: Preliminary surgical outcome, evaluated at 6 months after surgery, revealed a significant improvement of neurological function. Image analysis revealed that the cervical canals were significantly expanded, with a mean reduction of 13.1% in the stenosis ratio. Lift-up laminoplasty was effective in the treatment of patients with myelopathy secondary to cervical OPLL, and the amount of expansion could be individually adjusted at the discretion of the surgeon. Conclusion: Although analysis with a larger population and a longer follow-up period needs to be undertaken, our method of lift-up laminoplasty appears to be a viable choice among standard posterior cervical approaches for cervical OPLL.

    We present a case of a 47-year-old-woman with a complaint of cervical pain with paresthetic appearance on her left arm. She was treated with analgetics. Further radiological evaluation because of the persistent pain revealed an osteolytic destruction of the fourth cervical vertebra. The patient underwent anterior cervical corpectomy with total excision of the tumor. Stabilization of the cervical spine was performed. Histology confirmed the diagnosis of Langerhans cell histiocytosis (LCH) of the cervical spine. This case report presents the histopathological evaluation, diagnostic work-up and the treatment procedures because of rarity of cervical spinal LCH cases in the literature. PMID:20669118

    Methods of CT of the cervical and thoracic spines were explained, and normal CT pictures of them were described. Spinal CT was evaluated in comparison with other methods in various spinal diseases. Plain CT revealed stenosis due to spondylosis or ossification of posterior longitudinal ligament and hernia of intervertebral disc. CT took an important role in the diagnosis of spinal cord tumors with calcification and destruction of the bone. CT scan in combination with other methods was also useful for the diagnosis of spinal injuries, congenital anomalies and infections.

    Full Text Available OBJECTIVE: To quantify the mobility of the lower cervical spine after seven years of total cervical disc replacement at two levels. METHOD: This clinical study was designed randomly and prospectively at the spine surgery center at the Hospital Nossa Senhora das Graças, in Canoas, RS-Brazil and at the Hospital Don João Becker, in Gravataí, RS-Brazil. Seventeen patients were included in the study that was designed to compare the data obtained from annual and sequential manner until the end of seven years. A comparison was made with the prior range of motion (ROM of each patient. All patients were diagnosed with not tractable symptomatic cervical degenerative disc disease with two adjacent levels between C-3 and C-7. RESULTS: A total of patients underwent TDR in two levels and at the end of seven years, only one patient was lost to follow-up. The pre and postoperative ROM was the same in the first three years however after the fourth year there was a gradual decline with a loss of 12% of preoperative ROM in flexion, 21% in extension and 23% in the right and left lateral bending at the end of seven years. CONCLUSIONS: The clinical outcome of this study is evidence level IV in evaluating the ROM for Moby-C(r for TDR in two adjacent levels at the lower cervical spine. These results show that the ROM is maintained during the first three years, gradually declining after that.

    Conclusions: Anterior cervical spine surgery is a safe approach and is associated with few major esophageal/pharyngeal complications, which most commonly include transient dysphagia and dysphonia. If symptoms persist, patients should be assessed for esophageal/pharyngeal defects utilizing appropriate imaging studies. Notably, even if the major complications listed above are adequately treated, optimal results are in no way guaranteed.

    This study reports 7 cases of cervical Pott's disease, gathered during 6 years in the department of neuro-surgery of Ibn Rochd U.H.C. 4 females and 3 males, aged between 9 and 52 years were included. All the patients complained of cervicobrachial pain and weakness of the limbs. Clinical features were: deterioration of general status, rachidian syndrome and neurological impairement with motor and sensitive deficit. Radiological analysis found a destructive and extensive lesion, cervical kyphosis from 10 degrees to 60 degrees, retropharyngeal abscess and intraspinal canal extension of infection. Diagnosis was confirmed by histological study in all cases. In addition to antituberculous therapy and preoperative cervical traction in 4 cases, all the patients had spinal fusion using an anterior approach. Post operative immobilization in a cervical collar varied from 9 to 12 months. All 7 patients had full neurological recovery, 6 patients had an excellent bony fusion and cervical kyphosis was corrected. For the remaining patient, the bone graft was mobilized without neurological disorders. This study confirms anterior arthrodesis efficiency. This procedure in conjunction with preoperative traction, allowed stabilization of the spine and healing of vertebral lesions with excellent kyphosis correction. PMID:9452797

    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...

    Twenty-two women (age range 25-49 years, average 30.9 years) and twenty-two men (age range 23-42 years, average 31.6 years), all healthy and asymptomatic, underwent passive flexion/extension examinations of the cervical spine. Functional x-rays were taken and analyzed using a computer-assisted method that quantified intervertebral rotations, translations, and locations of the centers of rotation for each level C1-C2-C6-C7. The aim of the study was to establish values for these parameters for a normal population as related to age and gender. In the process, a statistically significant difference was found in the average value of rotation between male and female groups at the C5-C6 level. A new parameter, the ratio between translation and rotation, was also established and may prove useful for clinical diagnoses. This parameter has a smaller error associated with it than do pure translations and may aid the clinician by helping to account for the large variation in rotatory ranges of motion within the population. This translation/rotation ratio indicated highly significant differences in the lower segments of the cervical spine between gender groups. PMID:1919845

    2016-07-01

    Tumoral calcinosis is an uncommon condition characterized by the calcification of periarticular soft tissue. In uremic patients the disease is secondary to metabolic disturbances in predisposed patients. The authors report the case of a 73-year-old woman who presented with a new painful cervical mass while undergoing continuous ambulatory peritoneal dialysis for long-standing end-stage renal disease (ESRD). A CT scan of the neck showed a lobulated, calcified mass in the left paraspinal soft tissue at C2-3. This mass affected the facet joint and also extended into the neural foramen but did not cause any neurological compromise. Due to the patient's significant medical comorbidities, resection was deferred and the patient was followed in the clinic. Subsequent repeat imaging has shown a significant decrease in the size of the mass. In the context of ESRD, a diagnosis of uremic tumoral calcinosis (UTC) was made. The authors conducted a search of the PubMed and EMBASE databases and identified 7 previously reported cases of UTC of the cervical spine. They present a summary of these cases and discuss the etiology, diagnosis, and management of the condition. Although the metabolic disturbances seen in patients undergoing dialysis can lead to tumoral calcinosis, most reported cases involve large joints such as the shoulder or the hip; however, the spine can also be affected and should be considered in the differential diagnosis of patients with uremia as it can mimic aggressive bone-forming neoplasms.

    2001-01-01

    Objective: To provide the experience in imaging diagnosis of cervical spine and spinal cord injuries in children.Methods: Imaging data of cervical spine and spinal cord injuries in 62 children were retrospectively reviewed.The routine radiography including the lateral,anteroposterior and open-mouth odontoid views were performed in all the patients. Tomography was available for 25 patients, and flexion-extension lateral views for 28patients, CT scanning for 21 patients, MRI for 26 patients.Results: Of these patients, 46 patients were identified with injuries of upper cervical spine (9 with atlantal arch fracture, seven with axial fracture, 21 with odontoid fracture, 1 with atlantal arch fracture combining with odontoid fracture, and 1 with atlantal transverse ligament disruption); 7 patients sustained injuries of lower cervical spine (3 fractures of vertebral body, 2 dislocations and 6fracture-dislocations ); 2 patients had multiple noncontiguous cervical injuries; and 3 had cervical spinal cord injury without radiographic abnormalities (SCIWORA).Conclusions: Imaging assessment is of great importance in the diagnosis of cervical spine and spinal cord injuries in children. Whenever cervical spine and spinal cord injuries are suspected for children patients, and the three-views should be routinely indicated. MRI should be routinely performed in all children with cervical SCIWORA.

    Full Text Available Temporomandibular dysfunction (TMD is considered to be associated with imbalance of the whole body. This study aimed to evaluate the influence of TMD therapy on cervical spine range of movement (ROM and reduction of spinal pain. The study group consisted of 60 patients with TMD, cervical spine pain, and limited cervical spine range of movements. Subjects were interviewed by a questionnaire about symptoms of TMD and neck pain and had also masticatory motor system physically examined (according to RDC-TMD and analysed by JMA ultrasound device. The cervical spine motion was analysed using an MCS device. Subjects were randomly admitted to two groups, treated and control. Patients from the treated group were treated with an occlusal splint. Patients from control group were ordered to self-control parafunctional habits. Subsequent examinations were planned in both groups 3 weeks and 3 months after treatment was introduced. The results of tests performed 3 months after the beginning of occlusal splint therapy showed a significant improvement in TMJ function (P>0.05, cervical spine ROM, and a reduction of spinal pain. The conclusion is that there is a significant association between TMD treatment and reduction of cervical spine pain, as far as improvement of cervical spine mobility.

    Injuries to the cervical spine are among the most serious injuries occurring as a result of participation in rugby. Outcomes of such injuries range from complete recovery to death, depending on the degree of spinal cord damage sustained. Much information has been gained regarding the mechanisms and frequency of such injuries, from case reports and case series studies. The most commonly reported mechanism of injury has been hyperflexion of the cervical spine, resulting in fracture dislocation of C4-C5 or C5-C6. Tracking both the trends of incidence of spinal injuries, and the effectiveness of injury prevention initiatives has proved difficult because of a lack of properly conducted epidemiological studies. Within the constraints of the research published to date, it appears that hookers and props have been at disproportionate risk of cervical spine injury, predominantly because of injuries sustained during scrummaging. While the scrum was the phase of play most commonly associated with spinal injuries throughout the 1980s in most rugby playing countries, there has been a trend through the 1990s of an increasing proportion of spinal injuries occurring in the tackle situation. The majority of injuries have occurred early in the season, when grounds tend to be harder, and players are lacking both practice and physical conditioning for the physical contact phases of the sport. A number of injury prevention measures have been launched, including changes to the laws of the game regarding scrummaging, and education programmes aimed at enforcing safe techniques and eliminating illegal play. Calls for case-registers and effective epidemiological studies have been made by researchers and physicians in most countries where rugby is widespread, but it appears to be only recently that definite steps have been made towards this goal. Well-designed epidemiological studies will be able to provide more accurate information about potential risk factors for injury such as age, grade

Methods Forty patients undergoing posterior cervical spine surgeries were randomized into two groups (group L and C) with 20 each. Patients in group L received 20 ml of 0. 5% ropivacaine local infiltration before skin closure.. Patients1 in both groups received lornoxicam 8 mg intravenously as a loading dose followed by PCIA (lornoxicam 16 mg/dl). Visual analog scores (VAS) were recorded at 4, 8, 12, 24 and 48 h postoperatively. Total bolus dosage, additional analgesics and complications were also compared. Results VAS scores in group L were significantly lower than that in group C at 4, 12, 24, 48 h postoperatively (P<0. 05). Total bolus dosages in group L were significantly less than that in group C (P<0. 01). Conclusion Ropivacaine local infiltration combined with lornoxicam for PCIA can be safely and efficiently used in posterior cervical spine surgery.

    2016-01-01

    Background Vertebroplasty (VP) and kyphoplasty (KP) are two minimally invasive techniques used to relieve pain and restore stability in metastatic spinal disease. However, most of these procedures are performed in the thoracolumbar spine, and there is limited data on outcomes after VP/KP for cervical metastases. The purpose of this article is to evaluate the safety and efficacy of VP and KP for treating pain in patients with cervical spine metastases. Methods A systematic review of the literature was conducted using the PubMed and Medline databases. Only studies that reported five or more patients treated with VP/KP in the cervical spine were included. Levels of evidence and grades of recommendation were established based on the Oxford Centre for Evidence-Based Medicine guidelines. Data was pooled to perform a meta-analysis for pain relief and complication rates. Results Six studies (all level 4 studies) met the inclusion criteria, representing 120 patients undergoing VP/KP at 135 vertebrae; the most common addressed level was C2 in 83 cases. The average volume of injected cement was 2.5 ± 0.5 milliliters at each vertebra. There were 22 asymptomatic cement leaks (16%; 95% CI, 9.8% - 22.2%) most commonly occurring in the paraspinal soft tissue. There were 5 complications (4%; 95% CI, 0.5% - 7.5%): 3 cases of mild odynophagia, 1 case of occipital neuralgia secondary to leak, and 1 case of stroke secondary to cement embolism. Pain relief was achieved in 89% of cases (range: 80 - 100%). The calculated average pain score decreased significantly from 7.6 ± 0.9 before surgery to 1.9 ± 0.8 at last evaluation (p=0.006). Conclusion Although the calculated complication rate after VP/KP in the cervical spine is low (4%) and the reported pain relief rate is approximately 89%, there is lack of high-quality evidence supporting this. Future randomized controlled trials are needed. PMID:26913227

    CT-Myelography (CTM) is routinely used for planning surgery for degenerative disease of the spine, but its invasive nature, significant potential morbidity, and high costs make a noninvasive substitute desirable. We report our work on evaluating CT and MR image fusion as an alternative to CTM. Because the spine is only piecewise rigid, a multi-rigid approach to the registration of spinal CT and MR images was developed (SPIE 2004), in which the spine on CT images is first segmented into separate vertebrae, each of which is then rigidly registered with the corresponding vertebra on MR images. The results are then blended to obtain fusion images. Since they contain information from both modalities, we hypothesized that fusion images would be equivalent to CTM. To test this we selected 34 patients who had undergone MRI and CTM for degenerative disease of the cervical spine, and used the multi-rigid approach to produce fused images. A clinical vignette for each patient was created and presented along with either CT/MR fusion images or CTM images. A group of spine surgeons are asked to formulate detailed surgical plans based on each set of images, and the surgical plans are compared. A similar study assessing diagnostic agreement is being performed with neuroradiologists, who also assess the accuracy of registration. Our work to date has demonstrated the feasibility of segmentation and multi-rigid fusion in clinical cases and the acceptability of the questionnaire to physicians. Preliminary analysis of one surgeon's and one neuroradiologist"s evaluation has been performed.

    Rosli, Ruwaida; Kashani, Jamal; Kadir, Mohammed Rafiq Abdul

    There are many cases of injury in the cervical spine due to degenerative disorder, trauma or instability. This condition may produce pressure on the spinal cord or on the nerve coming from the spine. The aim of this study was, to analyze the stabilization of the cervical spine after undergoing laminectomy via computational simulation. For that purpose, a three-dimensional finite element (FE) model for the multilevel cervical spine segment (C1-C7) was developed using computed tomography (CT) data. There are various decompression techniques that can be applied to overcome the injury. Usually, decompression procedures will create an unstable spine. Therefore, in these situations, the spine is often surgically restabilized by using fusion and instrumentation. In this study, a lateral mass screw-rod fixation was created to stabilize the cervical spine after laminectomy. Material properties of the titanium alloy were assigned on the implants. The requirements moments and boundary conditions were applied on simulated implanted bone. Result showed that the bone without implant has a higher flexion and extension angle in comparison to the bone with implant under applied 1Nm moment. The bone without implant has maximum stress distribution at the vertebrae and ligaments. However, the bone with implant has maximum stress distribution at the screws and rods. Overall, the lateral mass screw-rod fixation provides stability to the cervical spine after undergoing laminectomy.

    Full Text Available Background: Proprioception plays an important role in sensorimotor control of posture and movement. Impairments in cervical proprioception have been demonstrated in subjects with whiplash-associated disorder, patients with age-related degeneration, and patients with articular diseases or spondylosis. The joint position error test is widely used to measure head repositioning accuracy. Objective: The purpose of this pilot study was to compare cervical spine joint position error in females who routinely wear headscarves to females that do not wear headscarves. Methods: Twelve females with mean age 27.5±4.0 years were divided into two groups: females who routinely wear headscarves (n=6, and females who never wear headscarves (n=6. Joint position error was measured using a head-mounted laser while subjects were seated. The tasks involved relocating the head to neutral after flexion, extension, right rotation, and left rotation. A total of six trials were done for each direction. Results: The joint position error was higher in females wearing headscarves compared to females who do not wear them in the cumulative joint position error score (8.2±1.0 vs. 4.4±1.0, p=0.06 as well as during head rotation to the right (9.3±1.6 vs. 3.1±1.6, p=0.06. Conclusion: Wearing headscarves may increase the cervical joint position error and can negatively impact postural control. However, further studies are needed to confirm this finding.

    OBJECTIVE—To report the efficacy of conservative treatment with cervical traction and immobilisation with a Halo vest, in two consecutive rheumatoid arthritis patients with progressive cervical myelopathy caused by subaxial subluxation.
METHODS—Description of neurological symptoms and signs and findings in plain radiography (PR) and magnetic resonance imaging (MRI) of the cervical spine before and after treatment of the subaxial subluxation by traction and immobilisation with a Halo vest during four months.
RESULTS—During four months of traction and immobilisation neurological examination showed a considerable improvement of the signs and symptoms of cervical myelopathy. Afterwards PR and MRI of the cervical spine showed reduction of the subaxial subluxation. Eventually firm stabilisation was obtained in both patients without surgery of the cervical spine.
CONCLUSION—Cervical traction and immobilisation with a Halo vest can be considered as an independent conservative treatment in rheumatoid arthritis patients with cervical myelopathy caused by subaxial subluxation.

    The anatomy of the cervical spine of mature horses based on images obtained with a helical computed tomography examination performed on anatomic specimens was studied. Computed tomography was the diagnostic imaging method of choice and allowed three-dimensional reconstructions of images and other anatomical planes, such as coronal and sagittal. All images were acquired and evaluated in the filter and window to bone tissue. It was possible to demonstrate the anatomical differences and peculiarities of the normal vertebrae, particularly the occipito-atlantoaxial region, which has a higher incidence of changes to assist in the visualization of any change of the bone pattern on CT studies.

    In the mid 1970s, UMTRI investigated the biomechanical properties of the head and neck using 180 "normal" adult subjects selected to fill eighteen subject groups based on age (young, mid-aged, older), gender, and stature (short, medium, and tall by gender). Lateral-view radiographs of the subjects' cervical spines and heads were taken with the subjects seated in a simulated automotive neutral posture, as well as with their necks in full-voluntary flexion and full-voluntary extension. Although the cervical spine and lower head geometry were previously measured manually and documented, new technologies have enabled computer digitization of the scanned x-ray images and a more comprehensive and detailed analysis of the variation in cervical spine and lower head geometry with subject age, stature, and gender. After scanning the radiographic images, 108 skeletal landmarks on the cervical vertebrae and 10 head landmarks were digitized. The resulting database of cervical spine and head geometry was used to study cervical spine curvature, vertebral dimensions, and head/neck orientation as functions of age, gender, and stature. The data were used to characterize neutral posture cervical spine curvatures using two methods: a curvature index and Bézier spline functions. Lateral-view vertebral dimensions were also calculated for each subject, and a cascading series of equations was developed to estimate vertebral size and shape for a selected age, stature, and gender. The orientation of the cervical spine was defined using a neck chord angle, where the neck chord was varied to use different anatomical landmarks and estimates of joint centers for the top and bottom of the neck chord. Results from the study have been incorporated into a MS-Access based software package that allows researchers and modelers to generate cervical spine geometries for occupants of a specified age, gender, and stature. The program allows selection of individual occupants from the database that meet

    Conclusion: We feel that on table decompression and reduction followed by anterior stabilization can be used as the initial surgical approach to manage most types of cervical injuries. In rotation/translational cases where reduction cannot be achieved, monitored cervical traction on the decompressed spine can safely achieve reduction and hence avoid the need for a posterior facetectomy in a large percentage of cases.

    Surgical management of lumbar spine conditions can produce excellent outcomes in athletes. Microdiscectomy for lumbar disc herniation has favorable outcomes; most athletes return to play at preoperative performance levels. Direct pars repair is successful in younger athletes, with high rates of return to play for a variety of fixation techniques. Fusion in athletes with scoliosis is a negative predictor. There are few evidence-based return to play criteria. Athletes should demonstrate full resolution of symptoms and flexibility, endurance, and strength before returning to play. Deciding when to return an athlete to sport depends on particular injury sustained, sport, and individual factors. PMID:27543402

    2015-09-01

    Full Text Available Congenital absence of cervical spine pedicle can be easily misdiagnosed as facet dislocation on plain radiographs especially in the acute trauma setting. Additional imaging, including computed tomography (CT-scan with careful interpretation is required in order to not misdiagnose cervical posterior arch malformation with subsequent inappropriate management. A 39-year-old patient presented to the emergency unit of our university hospital after being trampled by a cow over her back and head followed by loss of consciousness, retrograde amnesia and neck pain. Her initial cervical CT-scan showed possible C5-C6 dislocation, then, it became clear that her problem was a misdiagnosed congenital cervical abnormality. Patient was treated symptomatically without consequences. The congenital absence of a cervical pedicle is a very unusual condition that is easily misdiagnosed. Diagnosis can be accurately confirmed with a CT-scan of the cervical spine. Symptomatic conservative treatment will result in resolution of the symptoms.

    Numerous finite element models of the cervical spine have been proposed, with exact geometry or with symmetric approximation in the geometry. However, few researches have investigated the sensitivity of predicted motion responses to the geometry of the cervical spine. The goal of this study was to evaluate the effect of symmetric assumption on the predicted motion by finite element model of the cervical spine. We developed two finite element models of the cervical spine C2-C7. One model was based on the exact geometry of the cervical spine (asymmetric model), whereas the other was symmetric (symmetric model) about the mid-sagittal plane. The predicted range of motion of both models-main and coupled motions-was compared with published experimental data for all motion planes under a full range of loads. The maximum differences between the asymmetric model and symmetric model predictions for the principal motion were 31%, 78%, and 126% for flexion-extension, right-left lateral bending, and right-left axial rotation, respectively. For flexion-extension and lateral bending, the minimum difference was 0%, whereas it was 2% for axial rotation. The maximum coupled motions predicted by the symmetric model were 1.5° axial rotation and 3.6° lateral bending, under applied lateral bending and axial rotation, respectively. Those coupled motions predicted by the asymmetric model were 1.6° axial rotation and 4° lateral bending, under applied lateral bending and axial rotation, respectively. In general, the predicted motion response of the cervical spine by the symmetric model was in the acceptable range and nonlinearity of the moment-rotation curve for the cervical spine was properly predicted.

    Background and Methods: As with any evolving surgical discipline, it is difficult to predict the future of the practice and science of spine surgery. In the last decade, there have been dramatic developments in both the techniques as well as the tools employed in the delivery of better outcomes to patients undergoing such surgery. In this article, we explore four specific areas in spine surgery: namely the role of minimally invasive spine surgery; motion preservation; robotic-aided surgery an...

    In this paper, we address the issue of computer-assisted indexing in one specific case, i.e., for the 17,000 digitized images of the spine acquired during the National Health and Nutrition Examination Survey (NHANES). The crucial step in this process is to accurately segment the cervical and lumbar spine in the radiographic images. To that end, we have implemented a unique segmentation system that consists of a suite of spine-customized automatic and semi-automatic statistical shape segmentation algorithms. Using the aforementioned system, we have developed experiments to optimally generate a library of spine segmentations, which currently include 2000 cervical and 2000 lumbar spines. This work is expected to contribute toward the creation of a biomedical Content-Based Image Retrieval system that will allow retrieval of vertebral shapes by using query by image example or query by shape example.

    Radiological investigations contribute little in differentiating the problems of patients with whiplash injuries. Nevertheless the more prolonged cases of whiplash injuries must not be attributed to preexisting degenerative disease, despite radiologically-proven medicolegal opinion. In this study, 60 patients who were seen for whiplash injuries in the Department for Trauma and Reconstructive Surgery at the University Hospital Hamburg-Eppendorf for clinical and radiological evaluation, an average of 5.7 years post injury, were divided into two groups (n = 30) depending on radiologically-proven preexisting degenerative changes of the cervical spine. On average the patients with degenerative changes were 11.2 years older than those with healthy vertebral columns and also demonstrated an increase in acute symptoms in the lower cervical spine (cervicobrachial syndrome). The chronicity of individual symptoms such as neck-pain, dizziness, nausea and psychological illness was also observed in both groups. Problems such as paresthesias as well as pain in the shoulder-arm-area appeared to increase in subsequent check-ups, irrespective of the earlier degenerative changes. Patients with typical posterior headaches recovered faster when they had radiologically normal spines. Presenting late, there was a significant accumulation of patients with pre-existing degenerative changes complaining merely of tinnitus. The earlier changes in any individual motion segment do not determine the clinical course of whiplash injuries, but merely represent an area of increased vulnerability to trauma. On the other hand, trauma has not been proven to influence the development or aggravation of degenerative changes in normal or diseased spines. We are not able to differentiate the posttraumatic course from the natural history of the degenerative process, either clinically or radiologically. Considering the involvement of sensitive neurological structures the classical objective organic diagnosis

  17. Collateral Adverse Outcomes After Lumbar Spine Surgery.

    2016-01-01

    Collateral adverse outcomes are the expected or unavoidable results of a procedure that is performed in a standard manner and typically experienced by the patient. Collateral adverse outcomes do not result from errors, nor are they rare. Collateral adverse outcomes occur as the direct result of a surgical procedure and must be accepted as a trade-off to attain the intended benefits of the surgical procedure. As such, collateral adverse outcomes do not fit into the traditional definition of a complication or adverse event. Examples of collateral adverse outcomes after lumbar spine arthrodesis include lumbar stiffness, postoperative psychological stress, postoperative pain, peri-incisional numbness, paraspinal muscle denervation, and adjacent-level degeneration. Ideally, a comparison of interventions for the treatment of a clinical condition should include information on both the negative consequences (expected and unexpected) and potential benefits of the treatment options. The objective evaluation and reporting of collateral adverse outcomes will provide surgeons with a more complete picture of invasive interventions and, thus, the improved ability to assess alternative treatment options.

    Full Text Available Intervertebral fusion through an anterior approach with polymethylacrylate is a wellestablished neurosurgical technique in the treatment of cervical spine degeneration. However, questions still remain concerning the post-surgical outcome. Factors influencing surgical outcome that could help to predict which patients need further post-surgical treatment and what to expect after surgery are the subject of numerous studies. In the present study, we retrospectively collected data from patients who had undergone intervertebral fusion and defined which pre-operative factors could influence the surgical outcome. Between 1993 and 1997, 379 patients were surgically treated with the ventral fusion technique in our hospital. In 2006, we sent a questionnaire to the patients and 164 responses were received. We identified pre-operative presence of severe pain, hypesthesia, palsy and gait disturbance as negative predictive factors, whereas age, body mass index, pre-operative physical strain and the cervical segment involved did not seem to influence prognosis. In conclusion, identifying preoperative factors which influence prognosis after intervetebral fusion will help predict postoperative outcome.

    Full Text Available Background: Subaxial cervical spine dislocations are common and often present with neurological deficit. Posterior spinal fusion has been the gold standard in the past. Pain and neck stiffness are often the presenting features and may be due to failure of fixation and extension of fusion mass. Anterior spinal fusion which is relatively atraumatic is thus favored using autogenous grafts and cages with anterior plate fixation. We evaluated fresh frozen fibular allografts and anterior plate fixation for anterior fusion in cervical trauma. Materials and Methods: Sixty consecutive patients with single-level dislocations or fracture dislocations of the subaxial cervical spine were recruited in this prospective study following a motor vehicle accident. There were 38 males and 22 females. The mean age at presentation was 34 years (range 19-67 years. The levels involved were C5/6 ( n = 36, C4/5 ( n = 15, C6/7 ( n = 7 and C3/4 ( n = 2. There were 38 unifacet dislocations with nine posterior element fractures and 22 were bifacet dislocations. Twenty-two patients had neurological deficit. Co-morbidities included hypertension ( n = 6, non-insulin-dependent diabetes mellitus ( n = 2 and asthma ( n = 1. All patients were initially managed on skull traction. Following reduction further imaging included Computerized Tomography and Magnetic Resonance Imaging. Patients underwent anterior surgery (discectomy, fibular allograft and plating. All patients were immobilized in a Philadelphia collar for eight weeks (range 7-12 weeks. Eight patients were lost to follow-up within a year. Follow-up clinical and radiological examinations were performed six-weekly for three months and subsequently at three-monthly intervals for 12 months. Pain was analyzed using the visual analogue scale (VAS. The mean follow-up was 19 months (range 14-39 months. Results: Eight lost to followup, hence 52 patients were considered for final evaluation. The neurological recovery was 1.1 Frankel

    Objective To evaluate the outcome of open-door laminoplasty for the treatment of failed anterior cervical spine surgery. Methods From February 2003 to June 2009, 15 patients underwent opendoor laminoplasty for the failed anterior cervical spine surgery. The causes of revision and the progression of disease were analyzed. Japanese Orthopedic Association (JOA)scores and Nurick grade were adopted to record the improvement of neurological status and walking ability. Results Two patients were excluded for analysis because of lost follow-up and follow-up less than 12 months. The mean follow-up period after revision surgery for the other 13 patients was 26 months (ranged 13-52 months). The mean interval between the initial and revision surgery was 24 months ( ranged 5 months to 6 years). The causes of revision were as following: degeneration of the adjacent segment in 2 cases, inadequate decompression in 5 cases, misdiagnosis of ossification of posterior longitudinal ligament(OPLL) as myelopathy in 4 cases, and progression of OPLL in 2 cases. Posterior laminoplasty was recommended for each patient. After the operation,13 patients improved neurologically with respect to JOA score, 12 patients improved their walking ability while 1 remained unchanged. The mean modified JOA scores improved from 10. 5 to 13.8 ( P < 0. 05 ), the average recovery rate was 53.0% after the revision operation. The mean overall Nurick grade was 3.1 preoperatively and 1.9 at the final follow-up ( P < 0.05 ), the mean improvement of the Nurick grade was 1. 2. Complications included cerebrospinal fluid leakage in 1 case, new axial neck pain in 1 case, and transient C5 nerve root palsy in 1 case. Conclusions Open-door laminoplasty is a straightforward and effective treatment for failed anterior cervical spine surgery due to inadequate decompression, progressive OPLL or degeneration of the adjacent segment. The merit of the open-door laminoplasty for failed anterior spine fusion is able to avoid

    Complete resection of spinal nerve sheath tumors (NSTs) does not always result in significant neurological deficit. The purpose of this retrospective case analysis was to discuss the optimal surgical strategy for spinal NST of the cervical spine. Twenty-four patients who underwent surgery for solitary cervical NST over the past decade were included in this retrospective study. Patients with neurofibromatosis or schwannomatosis were excluded. Seventeen of the 24 cases (70.8%) showed extradural dumbbell extension, most frequently at the C1 or C2 vertebral level. Neurological condition was assessed using the modified McCormick functional schema and sensory pain scale. Total removal of the tumor was achieved in 20 of 24 cases (83.3%). Staged surgery using combined anterior and posterior approaches was applied for 2 of 17 cases with extradural dumbbell extension. Tumor involvement with nerve root fibers critical for upper extremity function (C5-C8) was recognized in 6 of 24 cases (25.0%), with complete resection in all 6 cases. Final assessment of neurological function revealed satisfactory or acceptable recovery in all 6 patients. Spinal NSTs with extradural dumbbell extension are a common condition in the cervical spine. Complete removal of spinal NST of the cervical spine may carry a risk of permanent neurological deficit, but such sequelae appeared to be the exception in the present case analysis. A radical and safe surgical strategy, including staged surgery combining anterior and posterior approaches, should be tailored to the individual case. PMID:25367583

    The lumbosacral area is one of the most frequently operated spine regions because of the prevalence of disease in that area. Although a lumbosacral soft tissue defect after surgery due to inflammation and other causes is rare, such soft tissue defects are difficult to treat. Therefore, suitable methods for treating lumbosacral soft tissue defects are necessary. Therefore, this study introduces a case-treated with a transverse lumbosacral rotational flap.

  5. Demoralization, Patient Activation, and the Outcome of Spine Surgery.

    Block, Andrew R

    2016-01-01

    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 Objectives Major differences exist in the anatomy and biomechanics of the growing spine that causes failure patterns different from those in adults. Spinal injury in the pediatric patient is a main concern because timely diagnosis and appropriate treatment can prevent further neurologic damage and deformity and potentiate recovery. We conducted a retrospective clinical study of 137 cases (93 boys, 44 girls of pediatric cervical spine injuries, managed over fifteen years, to present data from a large series of pediatric patients with cervical spine injuries from a single regional trauma center. The aim was to assess and analyze complications, etiology, pathogenesis, site of injuries and age difference of cervical spine and spinal cord injury in a pediatric age group and compare the findings with current literature.Materials & Methods One hundred and thirty seven children with cervical spine injuries, seen over twelve years, were divided into two age groups: 54 patients were in group one (0-9 years and 83 patients were in group two (10 – 17 years . We managed them according to status at presentation and type of injury. Forty seven patients were managed surgically and ninety nonsurgically (52 wore a halo brace and 38 wore different hard collars and braces. T-test and Chi squares were used to analyze differences between groups ResultsThe most common cause of injury was motor vehicle accidents(MVA. Our younger patients (Group 1 had sustained more neurological injuries than the older ones (Group 2, 77% vs.48%.; upper cervical spine was the most common site involved in 76%, while 43% suffered head injuries. In group two, 88% of children two sustained fractures or fracture/ subluxations; also in this group, subluxation, and fracture/subluxation was present in 10 and 25% of children respectively. The most common radiological findings were vertebral fractures (38%. Solid fusions were demonstrated in all patients at late follow–up review (mean 6 years

  7. Utility of flexion-extension radiography for the detection of ligamentous cervical spine injury and its current role in the clearance of the cervical spine.

    Detecting the presence of injuries to the cervical spine is an important component of the initial assessment of patients sustaining blunt trauma. A small proportion of cervical spine injuries consists of ligamentous disruption. Accurate detection of ligamentous injury is essential as it may result in sequelae including radiculopathy, quadriplegia and death. Flexion-extension (FE) radiography has traditionally been utilised for the detection of ligamentous injury in patients who have been cleared of bony injury. There are controversies surrounding the use of FE for alert patients with neck pain. There are studies that call into question the diagnostic accuracy of FE, the high proportion of inadequate FE images due to muscle spasm and the adverse effects of prolonged cervical collar immobilisation while awaiting FE. Other literature indicates that FE provides no additional diagnostic information following a multi-detector helical computed tomography. This review evaluates the literature on the utility of FE for the detection of ligamentous injury and explores alternate strategies for clearing the cervical spine of ligamentous injury.

    When Langerhans cell histiocytosis (LCH) occurs at critical sites, such as in the cervical spine, there is a substantial risk for morbidity. Therefore, reports on clinical experiences with those patients remain important. We summarize the history of four patients with unifocal LCH at the cervical spine. All four patients received a biopsy to prove the histopathological diagnosis of LCH by demonstration of CD1a+cells. They were treated with oral prednisolone. All patients recovered completely and kept a normal function of the cervical spine. No reactivation of the disease occurred with an observation time of 3.4-7.3 years. This report contributes to the clinical experience for the treatment of LCH at critical sites. PMID:15076592

    Expandable vertebral body replacement cages (VBRs) have been widely used for reconstruction of the thoracolumbar spine following corpectomy. However, their use in the cervical spine is less common, and currently, no expandable cages on the market are cleared or approved by the US Food and Drug Administration for use in the cervical spine. The objective of this study was to perform a systematic review on the use of expandable cages in the treatment of cervical spine pathology with a focus on fusion rates, deformity correction, complications, and indications. A comprehensive Medline search was performed, and 24 applicable articles were identified and included in this review. The advantages of expandable cages include greater ease of implantation with less risk of damage to the end plate, less intraoperative manipulation of the device, and potentially greater control over lordosis. They may be particularly advantageous in cases with poor bone quality, such as patients with osteoporosis or metastatic tumors that have been radiated. However, there is a potential risk of overdistraction, which is increased in the cervical spine, their minimum height limits their use in cases with collapsed vertebra, and the amount of hardware in the expansion mechanism may limit the surface area available for fusion. The use of expandable VBRs are a valuable tool in the armamentarium for reconstruction of the anterior column of the cervical spine with an acceptable safety profile. Although expandable cervical cages are clearly beneficial in certain clinical situations, widespread use following all corpectomies is not justified due to their significantly greater cost compared to structural bone grafts or non-expandable VBRs, which can be utilized to achieve similar clinical outcomes.

    The purpose of our report is to describe a new application of kyphoplasty, the percutaneous anterolateral balloon kyphoplasty that we performed in two cases of metastatic osteolytic lesions in cervical spine. The first patient, aged 48 years, with primary malignancy in lungs had two metastatic lesions in C2 and C6 vertebrae. Patient's complaints were about pain and restriction of movements (due to the pain) in the cervical spine. The second patient, aged 70 years, with primary malignancy in stomach, had multiple metastatic lesions in thoracolumbar spine and C3, C4 and C5 vertebrae without neurological symptoms. The main symptoms were from cervical spine with severe pain even in bed rest and systematic use of opiate-base analgesic. The preoperative status was evaluated with X-rays, CT scan, MRI scan and with Karnofsky score and visual analogue pain (VAS) scale. Both patients underwent percutaneous anterolateral balloon kyphoplasty via the anterolateral approach in cervical spine under general anaesthesia. No clinical complications occurred during or after the procedure. Both patients experienced pain relief immediately after balloon kyphoplasty and during the following days. The stiffness also resolved rapidly and cervical collars were removed. VAS score significantly improved from 85 and 95 preoperatively to 30 in both patients. Karnofsky score showed also improvement from 40 and 30 preoperatively to 80 and 70, respectively, at the final follow-up (7 months after the procedure). Fluoroscopy-guided percutaneous anterolateral balloon kyphoplasty proved to be safe and effective minimally invasive procedure for metastatic osteolytic lesions of the cervical spine, reducing pain and avoiding vertebral collapse. Experience and attention are necessary in order to avoid complications.

    Full Text Available Introduction: Evaluation of cervical spine injuries makes up a major part of trauma patient assessments. Based on the existing sources, more than 98% of the cervical spine X-rays show no positive findings. Therefore, the present clinical audit aimed to evaluate the correlation of ordered cervical spine X-rays in multiple trauma patients with NEXUS and Canadian c-spine clinical decision rules. Methods: The present clinical audit, evaluated the correlation of cervical spine imaging orders in multiple trauma patients presented to the emergency department, with NEXUS and Canadian c-spine rules. Initially, in a pilot study, the mentioned correlation was evaluated, and afterwards the results of this phase was analyzed. Since the correlation was low, an educational training was planned for all the physicians in charge. Finally, the calculated correlations for before and after training were compared using SPSS version 21. Results: Before and after training, cervical spine X-ray was ordered for 98 (62.82% and 85 (54.48% patients, respectively. Accuracy of cervical spine X-ray orders, based on the standard clinical decision rules, increased from 100 (64.1% cases before training, to 143 (91.7% cases after training (p < 0.001. Area under the receiver operating characteristic (ROC curve regarding the correlation also raised from 52 (95% confidence interval (CI: 43 – 61 to 92 (95% CI: 87 – 97. Conclusion: Teaching NEXUS and Canadian c-spine clinical decision rules plays a significant role in improving the correlation of cervical spine X-ray orders in multiple trauma patients with the existing standards.

    Full Text Available Osteomyelitis of mandible as a delayed adverse event following radiation therapy has been widely reported; however, osteomyelitis of the cervical spine has rarely been reported. In this study, we reported our experience with a case of cervical spine osteomyelitis and epidural abscess after concurrent chemoradiotherapy (CCRT for hypopharyngeal carcinoma. The case involved a 68-year old man who underwent radical CCRT after a diagnosis of stage IVb, T4bN2cM0 posterior hypopharyngeal wall carcinoma. At 7 months after completing the initial therapy, the patient complained of severe pain in the neck and both shoulders and reduced muscular strength in the extremities. A large defect was found on the mucosa of posterior hypopharyngeal wall. On cervical magnetic resonance imaging, cervical spine osteomyelitis and an epidural abscess were observed. Because antimicrobial therapy was not effective, hyperbaric oxygen therapy was administered. Abscess reduction and improvement of the mucosal defect were observed. Because cervical spine complications after CCRT can be fatal upon worsening, adequate attention must be given.

    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

    Over 50 million Americans have low bone mass. Poor bone quality is known to complicate spinal fusion surgery, which relies on strong bony purchase to be effective. Unfortunately, many spine surgeons do not perform routine workups for either osteoporosis or osteomalacia. Effective screening and risk factor assessment can allow for appropriate medical management of osteoporosis in the perioperative setting, improving outcomes. Medical management can be grouped into several different categories: vitamins and minerals, bisphosphonates, recombinant parathyroid hormone, estrogen replacement or modification, inhibitors of receptor activator of nuclear factor κ-B ligand (RANKL), and calcitonin. Calcium and vitamin D supplements are the least expensive to prescribe, with minimal side effects and promising animal studies, and thus should be provided to most osteoporotic patients. Recombinant parathyroid hormone can also be considered, as clinical studies have demonstrated impressive results in spine fusion patients. Bisphosphonates, estrogen therapy or selective estrogen receptor modulators, and calcitonin should all be avoided in this patient population given unproven benefit and potentially harmful side-effect profiles. Denosumab is potentially an option, but may not be first line given the general lack of supporting data for its use in perioperative management of spine surgery patients. PMID:27100945

    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.

    Full Text Available Background: Truview laryngoscope provides an indirect view of the glottis and will cause less cervical spine movement since a ventral lifting force will not be required to visualize the glottis compared to Macintosh laryngoscope. Materials and Methods: A randomized crossover study to assess the degree of movement of cervical spine during endotracheal intubation with Truview laryngoscope was conducted in 25 adult ASA-I patients. After a standard anesthetic technique laryngoscopy was performed twice in each patient using in turn both the Macintosh and Truview laryngoscopes. A baseline radiograph with the head and neck in a neutral position was followed by a second radiograph taken during each laryngoscopy. An experienced radiologist analyzed and measured the cervical movement. Results: Significant cervical spine movement occurred at all segments when compared to the baseline with both the Macintosh and Truview laryngoscopes (P < 0.001. However, the movement was significantly less with Truview compared to the Macintosh laryngoscope at C 0 -C 1 (21%; P = 0.005 and C 1 -C 2 levels (32%; P = 0.009. The atlantooccipital distance (AOD traversed while using Truview laryngoscope was significantly less than with Macintosh blade (26%; P = 0.001. Truview blade produced a better laryngoscopic view (P = 0.005 than Macintosh blade, but had a longer time to laryngoscopy (P = 0.04. Conclusion: Truview laryngoscope produced a better laryngoscopic view of glottis as compared with Macintosh laryngoscopy. It also produced significantly less cervical spine movement at C 0 -C 1 and C 1 -C 2 levels than with Macintosh laryngoscope in patients without cervical spine injury and without manual in-line stabilization (MILS. Further studies are warranted with Truview laryngoscope using MILS.

    Positioning patients for spine surgery is pivotal for optimal operating conditions and operative-site exposure. During spine surgery, patients are placed in positions that are not physiologic and may lead to complications. Perioperative peripheral nerve injury (PPNI) and postoperative visual loss (POVL) are rare complications related to patient positioning during spine surgery that result in significant patient disability and functional loss. PPNI is usually due to stretch or compression of t...

    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.

    2007-06-01

    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.

    Full Text Available Abstract Background This study was aimed at evaluating whether or not patients with chronic type III acromioclavicular dislocation develop cervical spine pain and degenerative changes more frequently than normal subjects. Methods The cervical spine of 34 patients with chronic type III AC dislocation was radiographically evaluated. Osteophytosis presence was registered and the narrowing of the intervertebral disc and cervical lordosis were evaluated. Subjective cervical symptoms were investigated using the Northwick Park Neck Pain Questionnaire (NPQ. One-hundred healthy volunteers were recruited as a control group. Results The rate and distribution of osteophytosis and narrowed intervertebral disc were similar in both of the groups. Patients with chronic AC dislocation had a lower value of cervical lordosis. NPQ score was 17.3% in patients with AC separation (100% = the worst result and 2.2% in the control group (p Conclusions Our study shows that chronic type III AC dislocation does not interfere with osteophytes formation or intervertebral disc narrowing, but that it may predispose cervical hypolordosis. The higher average NPQ values were observed in patients with chronic AC dislocation, especially in those that developed cervical hypolordosis.

    2016-01-01

    We describe a case of a 19-year-old young man with oligoarthritis type of juvenile idiopathic arthritis, who presented with several month duration of lower neck pain and progressive muscular weakness of all four limbs. X-rays of the cervical spine demonstrated spontaneous apophyseal joint fusion from the occipital condyle to C6 and from C7 to Th2 with marked instability between C6 and C7. Surgical intervention began with anterolateral approach to the cervical spine performing decompression, insertion of cage and anterior vertebral plate and screws, followed by posterior approach and fixation. Care was taken to restore sagittal balance. The condition was successfully operatively managed with multisegmental, both column fixation and fusion, resulting in pain cessation and resolution of myelopathy. Postoperatively, minor swallowing difficulties were noted, which ceased after three days. Patient was able to move around in a wheelchair on the sixth postoperative day. Stiff neck collar was advised for three months postoperatively with neck pain slowly decreasing in the course of first postoperative month. On the follow-up visit six months after the surgery patient exhibited no signs of spastic tetraparesis, X-rays of the cervical spine revealed solid bony fusion at single mobile segment C6-C7. He was able to gaze horizontally while sitting in a wheelchair. Signs of myelopathy with stiff neck and single movable segment raised concerns about intubation, but were successfully managed using awake fiber-optic intubation. Avoidance of tracheostomy enabled us to perform an anterolateral approach without increasing the risk of wound infection. Regarding surgical procedure, the same principles are obeyed as in management of fracture in ankylosing spondylitis or Mb. Forestrier. PMID:27458558

    2014-01-01

    Full Text Available Background: Cervical spine immobilization results in a poor laryngeal view on direct laryngoscopy leading to difficulty in intubation. This randomized prospective study was designed to compare the laryngeal view and ease of intubation with the Macintosh, McCoy, and TruView laryngoscopes in patients with immobilized cervical spine. Materials and Methods: 60 adult patients of ASA grade I-II with immobilized cervical spine undergoing elective cervical spine surgery were enrolled. Anesthesia was induced with propofol, fentanyl, and vecuronium and maintained with isoflurane and nitrous oxide in oxygen. The patients were randomly allocated into three groups to achieve tracheal intubation with Macintosh, McCoy, or TruView laryngoscopes. When the best possible view of the glottis was obtained, the Cormack-Lehane laryngoscopy grade and the percentage of glottic opening (POGO score were assessed. Other measurements included the intubation time, the intubation difficulty score, and the intubation success rate. Hemodynamic parameters and any airway complications were also recorded. Results: TruView reduced the intubation difficulty score, improved the Cormack and Lehane glottic view, and the POGO score compared with the McCoy and Macintosh laryngoscopes. The first attempt intubation success rate was also high in the TruView laryngoscope group. However, there were no differences in the time required for successful intubation and the overall success rates between the devices tested. No dental injury or hypoxia occurred with either device. Conclusion: The use of a TruView laryngoscope resulted in better glottis visualization, easier tracheal intubation, and higher first attempt success rate as compared to Macintosh and McCoy laryngoscopes in immobilized cervical spine patients.

  13. Magnetic resonance imaging of the cervical and thoracic spine and the spinal cord

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MR), using a 0.3 T resistive scanner with an iron core and a vertical magnetic field, was evaluated in patients with different diseases affecting the cervical and thoracic spine and the spinal cord. The results indicate that MR is well suited as the procedure of choice for emergency examination of patients with spinal cord symptoms, for examination of patients with suspected spinal multiple sclerosis and for pre-operative evaluation of patients with rheumatoid arthritis with neurological symptoms emanating from the cranio-cervical junction. In patients with cervical radiculapathy and/or myelopathy, caused by spondylosis or disk herniation, MR was found to be equivalent with myelography and CT myelography but MR has several practical advantages. MR at 0.3 T using a vertical magnetic field provided information comparable to that reported from examinations performed with superconducting MR scanners. In order to optimize the MR examinations of the spine, the signal characteristics of different coils available when using a vertical magnetic field were determined by phantom studies. Recommendations for optimal coil selection for different levels of the cervical and thoracic spine are given. In addition, the paramagnetic contrast medium gadolinium-DTPA was administered intravenously to patients with suspected spinal multiple sclerosis. Enhancement of clinically active lesions in the cervical spinal cord was observed. Serial MR examinations with gadolinium-DTPA showed that a decrease in enhancement could be correlated with decrease in clinical symptoms and signs. (author)

    Postoperative syndrome after spine surgery, i.e., symptoms or syndromes caused by complications or procedure-related consequences, is gaining more and more importance. Due to great improvements concerning imaging and operative techniques (microsurgery, instrumentation) the total number of spinal surgeries as well as their related complications are increasing. Procedure-related postoperative complications including neurological deficit syndromes can occur acutely or at a later date. Concerning imaging techniques for postoperative evaluation after spinal surgery there are several modalities available. Their indications depend on complex factors including initial pathology the surgery was performed for, kind of surgical technique (surgical approach, instrumentation), anatomy of the patient as well as the time between onset of symptoms and surgery. In cases of ambiguous findings, the combination of different imaging techniques can be instrumental. (orig.) [German] Die moderne Bildgebung beim postoperativen Syndrom der Wirbelsaeule, d. h. Symptomen bzw. Symptomkomplexen aufgrund von Komplikationen oder prozedural bedingten Folgen eines Wirbelsaeuleneingriffs, gewinnt zunehmend an Bedeutung. Bei grossen Fortschritten auf den Gebieten der Diagnostik und operativen Techniken (Mikrochirurgie, moderne Instrumentation) ist die Gesamtzahl der Operationen und damit auch der prozedural bedingten Komplikationen gestiegen. Postoperative Beschwerden und/oder neurologische Ausfallsyndrome koennen akut oder zu einem spaeteren Zeitpunkt auftreten. Fuer die postoperative Bildgebung der Wirbelsaeule stehen verschiedene Verfahren zur Verfuegung, deren Indikationen von komplexen Faktoren wie initialer Pathologie, Art des Eingriffs (chirurgischer Zugang, Instrumentation), Anatomie des Patienten und der Zeit zwischen Operation und Symptombeginn abhaengen.

    1992-02-01

    Fifty-one patients suffering from soft tissue injury of the cervical spine underwent clinical and psychometric examination. Clinical interview evaluated subjective complaints and formal testing of self-estimated cognitive impairment, divided attention, and speed of information processing. Results indicated at least two different syndromes: 1) the "cervicoencephalic syndrome," characterized by headache, fatigue, dizziness, poor concentration, disturbed accommodation, and impaired adaptation to light intensity; and 2) the "lower cervical spine syndrome," which is accompanied by cervical and cervicobrachial pain. When comparing patients with either of these two syndromes, those suffering from cervicoencephalic syndrome had significantly poorer results when tested for divided attention. Speed of information processing was reduced to a comparable extent in both syndromes. These findings were not related to the length of the post-traumatic interval. Reduced processing of working memory is assumed, which may account for more global cognitive problems as well as secondary neurotic reaction. PMID:1553581

    Full Text Available Liposarcoma is the most common soft tissue sarcoma in adults. These tumors have a high incidence of osseous metastases, with a propensity to the spine; however, primary spinal involvement is very rare. A 56-year-old female patient presented with a 4 month history of cervical pain, including radiation to both upper limbs, without radicular distribution. Magnetic resonance imaging (MRI showed an epidural lesion with gadolinium enhancement and bilateral extension into the intervertebral neural foramina (C5–C7, with spreading on the right side of the tumor into paravertebral tissue. The histopathological diagnosis was myxoid liposarcoma. To our knowledge it is the first case of primary myxoid liposarcoma of the cervical spine in the literature. Although rare, our case demonstrates that liposarcoma should be considered in the differential diagnosis of cervical tumors.

  17. MIND Demons for MR-to-CT deformable image registration in image-guided spine surgery

    2016-03-01

    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

    Full Text Available Chao Zhang, Dike Ruan, Qing He, Tianyong Wen, Pushan YangDepartment of Orthopedic Surgery, Navy General Hospital, Beijing, People's Republic of ChinaAbstract: Diffuse idiopathic skeletal hyperostosis (DISH is considered an underdiagnosed and mostly asymptomatic nonprimary osteoarthritis. The etiology of DISH remains unknown and the validated diagnostic criteria are absent. This condition is still recognized radiologically only. Rarely, large projecting anterior osteophytes result in esophageal impingement and distortion leading to dysphagia. We report the case of progressive dysphagia and neck pain due to DISH of the cervical spine in a 70-year-old man, which was surgically removed with excellent postoperative results and complete resolution of symptoms. Imaging studies, surgical findings, and histopathological examinations were used to support the diagnosis. The patient was successfully treated with total excision of the anterior osteophytes with no evidence of recurrence 12 months after surgery. In this report, we also discuss the clinical features and perioperative considerations in combination with a literature review. Our patient illustrates that clinicians should be aware of this rare clinical manifestation as the presenting feature of DISH in cervical spine. Surgical decompression through osteophytectomy is effective for patients who fail conservative treatment.Keywords: diffuse idiopathic skeletal hyperostosis, cervical spine, dysphagia

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

    Directory of Open Access Journals (Sweden)

    Murphy Donald R

    2009-08-01

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

    Full Text Available Background: Cervical spine and intervertebral discs are potentially prone to functional disorders. Objectives:This study sought type and distribution of different pathologies in the cervical spine and a possible relationship between the MRI findings and the probable risk factors of the degenerative disorders. Material and methods: This descriptive cross-sectional research was carried out from October 2000 to January 2002 in three referral centers in Tehran. All the patients had referred for cervical MRI for neck pain and/or radicular pain. Results: Totally 342 patients entered the study. Sixty percent of patients were male. The mean age was 55.1 12.1 years. Seventy-nine percent of patients had abnormal MRI findings (238 patients (70% had signs of degenerative processes and 31 patients (9% had the other findings with a total 308 pathologies. The most common findings were disc bulging/ protrusion (%21.1, disc dehydration (%20.1, disc herniation (%18.1, and canal stenosis(%17.5. Older age, male gender and history of neck trauma were associated with increasing probability of degenerative changes (P-Values<0.05. Conclusion: Types of cervical spine pathologies are comparable to other reports. The anatomical distribution of disc bulging and protrusion in our study are similar to other reports. Likewise age, gender and a history of trauma to the neck were closely associated with the degenerative signs on the MR images.

    Full Text Available We report a rare patient of a simultaneous extradural and intradural compression of the cervical spinal cord due to co-existent intervertebral disc herniation and an intradural schwannoma at the same level. The intradural lesion was missed resulting in recurrence of myelopathy after a surprisingly complete functional recovery following anterior cervical discectomy. Retrospectively, it was noted that the initial cord swelling noticed was tumor being masked by the compression produced by the herniated disc. A contrast magnetic resonance imaging scan is important in differentiating intradural tumors of the spinal cord. A high index of suspicion is often successful in unmasking both the pathologies.

  5. Absent cervical spine pedicle and associated congenital spinal abnormalities - a diagnostic trap in a setting of acute trauma: case report

    International Nuclear Information System (INIS)

    Congenital spinal abnormalities can easily be misdiagnosed on plain radiographs. Additional imaging is warranted in doubtful cases, especially in a setting of acute trauma. This patient presented at the emergency unit of our university hospital after a motor vehicle accident and was sent to our radiology department for imaging of the cervical spine. Initial clinical examination and plain radiographs of the cervical spine were performed but not conclusive. Additional CT of the neck helped establish the right diagnosis. CT as a three-dimensional imaging modality with the possibility of multiplanar reconstructions allows for the exact diagnosis and exclusion of acute traumatic lesions of the cervical spine, especially in cases of doubtful plain radiographs and when congenital spinal abnormalities like absent cervical spine pedicle with associated spina bifida may insinuate severe trauma

    MR imaging was found to be the most sensitive modality for the detection of spinal cord abnormalities in the acutely injured spine. Although it is reported that traumatic pneumomyelogram indicates a base-of-skull or middle cranial fossa fracture and is almost certainly associated with intracranial subarachnoid air, early MR imaging may demonstrate subarachnoid air in penetrating trauma of the spinal cord without head injury. We report two cervical-spine stab-wound cases, one of which had subarachnoid air on early MR findings. (orig.)

    Full Text Available Aim: It is not uncommon for vertebral artery injury to occur when there are fractures through the transverse foraminae of the first to the sixth vertebral bodies. Other important risk factors for vertebral artery injury include facet joint dislocations and fractures of the first to the third cervical vertebral bodies. The aim of this study was to determine the pattern and prevalence of vertebral artery injury on CT angiography (CTA in patients with cervical spine fractures.Method: A retrospective review of patients who had undergone CTA of the vertebral arteries was undertaken. Reports were reviewed to determine which patients met the inclusion criteria of having had both cervical spine fractures and CTA of the vertebral arteries. Images of patients who met the inclusion criteria were analysed by a radiologist.Results: The prevalence of vertebral artery injury was 33%. Four out of the 11 patients who had vertebral artery injury, had post-traumatic spasm of the artery, with associated thrombosis or occlusion of the vessel. In terms of blunt carotid vertebral injury (BCVI grading, most of the patients sustained grade IV injuries. Four patients who had vertebral artery injury had fractures of the upper cervical vertebrae, i.e. C1 to C3. Fifteen transverse process fractures were associated with vertebral artery injury. No vertebral artery injury was detected in patients who had facet joint subluxations.Conclusion: Patients with transverse process fractures of the cervical spine and upper cervical vertebral body fractures should undergo CTA to exclude vertebral artery injury.

    To study the relationship of upper thoracic spine degenerative disc contour changes on MR imaging in patients with neck pain. The relation between upper thoracic and cervical spine degenerative disc disease is not well established. One hundred and fifty-six patients referred with cervical pain were studied. There were 73 women and 77 men with a mean age of 48.6{+-}14.6 years (range, 19 to 83 years). All MR studies were performed with a large 23-cm FOV covering at least from the body of T4 to the clivus. Discs were coded as normal, protrusion/bulge or extrusion. Degenerative thoracic disc contour changes were observed in 13.4% of patients with cervical pain. T2-3 was the most commonly affected level of the upper thoracic spine, with 15 bulge/protrusions and one extrusion. Upper degenerative thoracic disc contour changes presented in older patients than the cervical levels (Student-Newman-Keuls test, P<0.001). Degenerative disc contour changes at the C7-T1, T1-2, T2-3 and T3-4 levels were significantly correlated (P=0.001), but unrelated to any other disc disease, patient's gender or age. Degenerative cervical disc disease was closely related together (P<0.001), but not with any thoracic disc. A statistically significant relation was found within the upper thoracic discs, reflecting common pathoanatomical changes. The absence of relation to cervical segments is probably due to differences in their pathomechanisms. (orig.)

    como uma opção terapêutica. A recuperação neurológica pós-cirurgica depende do nível de compromisso neurológico prévio, o que reforça a importância da detecção e derivação rápida do paciente com risco. O tratamento cirúrgico deve fazer-se em centros especializados, por grupos multidisciplinares. Isto, junto com a intervenção rápida, ajudaria a reduzir as complicações peri-operatórias.Rheumatoid arthritis affects millions of people all over the world. Up to 86% of cases involve cervical spine alterations. Cervical spine instability patterns related to rheumatoid arthritis are: atlanto-axial subluxation, basilar invagination and subaxial instability. Once neurological deficit develops, progression can be fast and even lead to death. Rheumatoid arthritis treatment is mainly nonsurgical. Current medication and treatment protocols may prevent or delay the development of atlanto-axial disease. Periodical clinical and radiological examination help diagnose patients who already have neurological symptoms or those who are at risk of developing them, and who should thus be considered for surgical treatment. Preoperative neurological deficit is a predictor of postoperative neurological recovery, thus the importance of early detection and referral of patients at risk. Surgical treatment should be performed in specialized centers, by multidisciplinary groups. Along with early intervention, this should help reduce perioperative complications.

  11. Perioperative Vision Loss in Spine Surgery and Other Orthopaedic Procedures.

    Science.gov (United States)

    Su, Alvin W; Lin, Shuai-Chun; Larson, A Noelle

    2016-10-01

    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.

    Full Text Available Purpose: Vertebral artery injuries (VAIs can be seen in cervical injuries. This investigation was conducted to assess the impact of head and neck computed tomography (CT angiography (CTA on planning treatment of vertebral artery injuries, if these tests were ordered appropriately, and to estimate cost and associated exposure to radiation and contrast material. Methods: This retrospective review included all patients who underwent CT of the cervical spine and CTA of the head and neck from March 2011 to October 2012 at a single institution. Patients were divided into two groups, those with and those without cervical spine fracture appreciated on CT of the cervical spine. The frequency of vascular injury on CTA in those with a cervical fracture was assessed. The frequency of vascular injury treatment and modifications owed to a positive CTA of head and neck were also assessed. A study was considered appropriate if it was ordered in accordance with the modified Denver Screening criteria. Effective radiation dose (mSv was calculated by multiplying dose length product (DLP from the scanner with the standard conversion coefficient (k (k = 0.0021 mSv/mGy x cm.Results: In the 387 CTAs of head and neck, a cervical injury was recorded in 128 patients. Twenty CTA scans were correctly ordered for non-spinal indications, and 19 were ordered off protocol. CTA was found positive in 1 patient for whom the imaging was off protocol and 1 for whom the clinical indication was non-cervical. There were 19 positive CTA cases of head and neck, none of which underwent surgical intervention. CTA was positive in 13 of 48 patients who had suffered a C2 fracture; this accounted for 13 of the 19 positive CTA studies (p < 0.01. Estimated fee for CTA was $3783, and radiation exposure was 4 mSv with a standard deviation (±1.3. Conclusion: CTA of head and neck ordered off an institutional imaging protocol has a low probability of being positive. Adherence to protocols for CTA of

  13. HAVE RECENT CHANGES TO THE RUGBY UNION LAWS OF SCRUMMAGE REDUCED SERIOUS CERVICAL SPINE INJURIES?

    Full Text Available All areas of play in rugby union are acknowledged to be potentially dangerous but it is in the scrum where the most frequent and serious spinal injuries occur (McIntosh & McCrory, 2005. This letter addresses the questions: what is it about the scrum which accounts for the alleged increased frequency of scrummage associated spinal cord injury (particular in the cervical region and what has the Rugby Football Union [RFU] done to minimise the chance of cervical cord damage by changes to the Laws? Scrums are used to restart play after infringement of Law 20.1. The team which is successful in winning the ball from the scrum can provide quality possession and space to their attacking backs (IRB, 2005.The three front row players are especially vulnerable to serious cervical spine injury. The majority of neck injuries are caused by heads not being properly aligned when opposing front row players make initial contact as the scrum is being formed. If the scrum collapses then excessive forward flexion/rotation of the cervical spine can occur and by wheeling the scrum this can result in increased abnormal lateral flexion/rotation. Added to these possible abnormal increases in directional movement of the cervical spine is the force generated at engagement. It has been calculated that in the front row a static weight of up to 1600kg is placed on each player's neck. Fracture dislocation (usually between C4/C6 of the spine can be the resulting injury which if the cord is involved can cause tetra paresis.In response to this evidence the IRB amended the law of scrummage which was put into effect 2007 in the hope of reducing the incidence of serious cervical spine injury. This is summarised as a 4 step Law of engagement which is: "crouch, touch, pause, engage". The distance between the front rows must now be less than arms length before making contact. Prior to the introduction of this Law with the stipulated distance apart before engagement, the front row

    1984-01-01

    In bad cases of whiplash injury of the cervical spine the post-accidental course is complicated by pain, vegetative dysfunctional syndromes and by psychic and psychiatric disorders over many years. There is no satisfactory concept to understand the pathophysiology of these processes. The paper deals with the possibility of a reflex dystrophy. Sympathetic reflex dystrophy syndromes are seen principally in patients with joint, tendon or vascular lesions. In case of whiplash injury, it would concern the cervical spine itself as well as visceral organs including the central nervous system. For the CNS the lymphostatic encephalopathy is a well defined entity. Above all, a reflex dystrophy develops on the basis of a special personality structure. In case of psychic and psychiatric complaints after whiplash injury patients with a so called Sudeck-personality should not be suspected to aggravate; in contrast, especially in these patients complications by reflex dystrophy are credible. Consequences for the assessment and for rehabilitation are discussed. PMID:6475217

    The evaluation by means of functional X-rays, of rotatory instability of the upper cervical spine as a result traumatic or inflammatory destruction of the ligamentous apparatus, is unsatisfactory. Functional CT of the upper cervical spine allows measurement of the segmental rotatory movements. 9 healthy juveniles and 30 patients were examined after neck injury via functional CT's. A rotation between occiput and atlas greater than 9/sup 0/, between atlas and axis over 50/sup 0/, the left-right difference at the level C0/C1 greater than 6/sup 0/ and at the level C1/C2 over 10.5/sup 0/ point to a suspicion of hypermobility or instability.

    Eosinophilic granuloma is a term reserved for the most often and benign form of disorder known as Langerhans cells histiocytosis. It is a disease of children and adolescents that very rarely affects adults, representing the localized form of a pathological proliferation of histiocytes in bones, like skull and long bones. Vertebral involvement is uncommon, approximately 8% of the cases, being the cervical localization the least affected. Moreover, the involvement of the spinal cord and roots remains a rare occurrence. Only five cases characterized by signs of cervical spinal cord compression have been reported. We report the sixth case in a 42-year-old-man who evolved with resolution of symptoms, and has remained asymptomatic after treatment. The clinical, radiological and histological features and, also, the value, in selected cases, of surgical treatment followed by low-dose radiation therapy is discussed. A review of the pertinent literature is also presented. PMID:10450361

    A 10-year review (1987-1996) of injuries sustained to the spine and spinal cord in rugby players with resultant paralysis has been undertaken. This article reviews that the incidence of serious rugby spine and spinal cord injuries in South Africa has increased over the 10-year period reviewed, despite stringent new rules instituted in an attempt to decrease the incidence of these injuries. The mechanisms of injury, as previously reported, remain the same as well as the phases of game responsible for injury of the tight scrum, tackle, rucks, and mauls. Two new observations are reported: the first is related to the occurrence of spinal cord concussion with transient paralysis, and the second is related to the increased incidence of osteoarthritis of the cervical spine in rugby players.

    Conclusions: The authors concluded that dexamethasone administered at the time of ACDF surgery improved swallowing within the 1 st postoperative month, reduced perioperative airway complications, reduced the length of stay, and reduced 6 month but not 12 month fusion rates. Although the findings regarding postoperative dysphagia are helpful, the performance of multiple 3D-CT scans postoperatively to document fusion would appear to subject these patients to excessive radiation exposure without sufficient clinical indications.

    The objective was to examine significant differences in the bony structure of cervical spine vertebrae based on gender and spinal level that may influence injury risk in women following automotive rear impact. Male and female subjects were recruited for a separate study and data from two subsets were selected for inclusion in this study. Subjects were size-matched based on sitting height (17 males, 11 females) and head circumference (9 males, 18 females). Axial CT scans were obtained of the cervical spine from the C1 through C6. Bony boundaries of cervical vertebrae were defined using image-analysis software and biomechanically-relevant dimensions were derived at spinal levels C2 through C6. Six of seven vertebral dimensions were significantly dependent upon gender and spinal level in both subgroups. Male vertebrae had larger dimensions for each metric. Depth dimensions were greatest at caudal and cranial extents, whereas width dimensions were smallest at C2 and increased caudally. Greater linear and areal dimensions in size-matched male subjects indicates a more stable cervical spinal column that may be more capable of resisting inertial loading of the head-neck complex during automotive rear impacts. Although the explanation for greater injury susceptibility in females is likely multi-factorial, including differences in spinal material properties, soft tissue tolerance thresholds, occupant-seatback orientation, and neck muscle size/orientations, the present study has identified significant differences in cervical spine anatomical dimensions that may contribute to greater rates of whiplash injury in that population.

    Full Text Available Purpose: To determine the degree of adherence to a cervical spine (c-spine clearance protocol by pre-hospital Emergency Medical Services (EMS personnel by both self-assessment and receiving hospital assessment, to describe deviations from the protocol, and to determine if the rate of compliance by paramedic self-assessment differed from receiving hospital assessment. Methods: A retrospective sample of pre-hospital (consecutive series and receiving hospital (convenience sample assessments of the compliance with and appropriateness of c-spine immobilization. The c-spine clearance protocol was implemented for Orange County EMS just prior to the April-November 1999 data collection period. Results: We collected 396 pre-hospital and 162 receiving hospital data forms. From the pre-hospital data sheet. the percentage deviation from the protocol was 4.096 (16/396. Only one out of 16 cases that did not comply with the protocol was due to over immobilization (0.2%. The remaining 15 cases were under immobilized, according to protocol. Nine of the under immobilized cases (66% that should have been placed in c-spine precautions met physical assessment criteria in the protocol, while the other five cases met mechanism of injury criteria. The rate of deviations from protocol did not differ over time. The receiving hospital identified 8.0% (13/162; 6/16 over immobilized, 7/16 under immobilized of patients with deviations from the protocol; none was determined to have actual c-spine injury. Conclusion: The implementation of a pre-hospital c-spine clearance protocol in Orange County was associated with a moderate overall adherence rate (96% from the pre-hospital perspective, and 92% from the hospital perspective, p=.08 for the two evaluation methods. Most patients who deviated from protocol were under immobilized, but no c-spine injuries were missed. The rate of over immobilization was better than previously reported, implying a saving of resources.

    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 We report the perioperative course of a patient with long standing ankylosing spondylitis with severe dysphagia due to large anterior cervical syndesmophytes at the level of the epiglottis. He was scheduled to undergo anterior cervical decompression and the surgical approach possibly precluded an elective pre-operative tracheostomy. We performed a modified awake fibreoptic nasal intubation through a split nasopharyngeal airway while adequate oxygenation was ensured through a modified nasal trumpet inserted in the other nares. We discuss the role of nasal intubations and the use of both the modified nasopharyngeal airways we used to facilitate tracheal intubation. This modified nasal fibreoptic intubation technique could find the application in other patients with cervical spine abnormalities and in other anticipated difficult airways.

  14. Symptomatic ossification of the posterior longitudinal ligament of the cervical spine: pictorial essay

    International Nuclear Information System (INIS)

    Symptomatic ossification of the posterior longitudinal ligament (OPLL) of the cervical spine is a rare but well documented condition. It is the causative factor in up to 5% of cases presenting with cervical radiculopathy or myelopathy. Computed tomography is the modality of choice in showing the distinctive characteristics and extent of the disease. Magnetic resonance imaging (MRI) is sensitive in detecting cord compression and its attendant complications. Cervical OPLL commonly affects those of middle and advanced age, and the condition is noted to be particularly common in Japanese, although other racial groups are also affected. A 'mushroom' or 'hill' shape on axial CT typifies OPLL. A sharp radiolucent line separating the posterior vertebral margin from the superficial component of the ossified ligament is a characteristic feature. Copyright (1999) Blackwell Science Pty Ltd

  15. Radiographic findings of degeneration in cervical spines of middle-aged soccer players

    International Nuclear Information System (INIS)

    Twelve amateur veteran soccer players (average age 40.1 ± 5.4 years), who began playing in their teens and who were admitted with symptoms most likely to be related to cervical spondylosis, were examined by cervical radiography. Abnormal radiographic findings included: calcification of anterior longitudinal ligament (25%), anterior (75%) and posterior vertebral spurs (75%), ossicle between spinous processes (75%), calcification of nuchal ligament (Barsony) (58%), ossicle on spinous process (25%), and bony spur of Luschka's joints (83%). It was shown in the stress distribution by finite element method analysis that the stress in heading the ball was applied mainly to the lower parts of the cervical spine. The results of this analysis also corresponded well with some of the radiographic findings. (orig.)

    23 cases of unstable traumatic lesions of the lower cervical spine, without neurologic complication, were treated over a period of eight years. These cases consisted of eight dislocations, five subluxations, nine fracture-dislocations and one "tear drop" or fracture of the vertebral body. Six cases were treated conservatively and fifteen operatively. Two patients died in skeletal traction while awaiting surgical intervention. The surgical approaches were anterior (6 cases), posterior (8 cases) and combined (1 case). There was one case of transitory neurologic deficit immediately after surgery. One case required re-intervention. Overall they obtained satisfactory osteoligamentary consolidation. PMID:2055985

    Full Text Available Background & Objectives: The most common etiology of neck pain is degenerative disc disease, however non-degenerative disease can be important cause of neck pain. This study aims to study the non-degenerative findings in cervical MRI in symptomatic patients with neck and radicular pain.Materials & Methods: The study was a institutional record based retrospective study performed for the duration of 3 years. MRI performed for patients with neck pain and/ or radiculopathy were reviewed. Patients with post operative findings were excluded from the study. Statistical analysis was done using SPSS 21.0.Results: A total of 721 MRI were performed for neck pain and radiculopathy, among which 91 (12.13% cases had non-degenerative changes. Most common non degenerative change was traumatic lesions followed by neoplastic lesions and syrinx. Traumatic lesions were more common in males as compared to females. Infection was more common in females as compared to males. C5 and C6 vertebrae were most common vertebra involved in trauma and infection. Some cases like signal change in spinal cord, and syrinx were also noted in our study.Conclusion: Non degenerative cause of neck pain were less common but important cause of neck pain. Traumatic lesions were the most common cause of non degenerative neck pain.Journal of College of Medical Sciences-Nepal, Vol.11(4 2015: 20-23

    Full Text Available 【Abstract】Objective: To report a case series of six neglected cervical spine dislocations without neurological deficit, which were managed operatively. Methods: The study was conducted from August 2010 to December 2011 and cases were selected from the out-patient department of Postgraduate Institute of Medical Education and Research, India. The patients were in the age group of 30 to 50 years. All patients were operated via both anterior and posterior approaches. Results: During the immediate postoperative period, five (83.33% patients had normal neurological status. One (16.67% patient who had C 5 -C 6 subluxation developed neu-rological deficit with sensory loss below C 6 level and motor power of 2/5 in the lower limb and 3/5 in the upper limb below C 6 level. Conclusion: There is no role of skull traction in ne-glected distractive flexion injuries to cervical spine delayed for more than 3 weeks. Posterior followed by anterior ap-proach saves much time. If both approaches are to be done in the same sitting, there is no need for instrumentation posteriorly. But if staged procedure is planed, posterior sta-bilization is recommended, as there is a risk of deterioration in neurological status.

    Full Text Available Background: There are very few published reports of upper cervical spine injuries from our country and there is a heavy bias towards operative treatment of these injuries. We present below our experience of upper cervical injuries over the last four years. Materials and Methods: Twenty eight patients (20 males, 8 females with upper cervical spine injury (including Occiput, Atlas and Axis were treated and were followed-up for an average of 11.2 months. The data was analyzed retrospectively with regards to the location and type of injury, the treatment offered (conservative or operative as well as the final clinical and radiological outcome. Results: The clinico-radiological outcome of treatment of these injuries is mostly very good with few complications. Other than a single case of mortality due to associated head injury there were no major complications. Conclusion: Management of these patients needs a proper evaluation to arrive at the type of injury and prompt conservative or operative treatment. Treatment is usually safe and effective with good clinical and radiological outcome.

    The cervical spine is the region of the column that articulates the head and chest. The tests of computed tomography (CT) performed in this region have as main objectives to diagnose fractures, dislocations and tumors. In CT scans the cervical spine volume is limited by the foramen Magnum and the first thoracic vertebra. In this region is the thyroid that is directly irradiated by X-ray beam during cervical scan. Based on this information, it was studied the dose variation deposited in thyroid and in nearby organs, such as: lenses, spinal cord in the foramen Magnum region and breasts, with and without the use of bismuth protector. In this study was used a male anthropomorphic phantom and thermoluminescent s dosimeters (TLD-100) were required to register the individual doses in the organs of interest. CT scans were performed on a GE Bright Speed scanner of 32 channels. With the data obtained, it was found the organ dose variation. The largest recorded dose was in the thyroid. Comparing two scans it was possible to note that the use of the bismuth protector promoted a 26% reduction in the thyroid dose and an increase in the lens dose. (Author)

    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

    Purpose: To document the MRI appearances of radiation-induced abnormalities in the cervical spine following treatment for nasopharyngeal carcinoma (NPC). Methods: Patients with radiation-induced abnormalities in the upper cervical spine were identified from a retrospective analysis of reports from patients undergoing MRI follow-up. Imaging and clinical records of these patients were reviewed. Symmetrical distribution of abnormalities at C1 (anterior arch {+-} adjacent aspect of the lateral masses) and C2 (dens {+-} body especially with a characteristic horizontal rim of marrow preservation above the inferior endplate) were considered typical for osteoradionecrosis (ORN). Results: Abnormalities of C1/2 were identified in 9/884 (1%) patients. The MRI distribution of abnormalities was typical for ORN in four and atypical in five patients. Abnormal soft tissue was present in the atlantoaxial joint in eight patients, forming a florid mass in six. This soft tissue was in direct continuity with the posterior nasopharyngeal wall ulceration via the retropharyngeal region. The final clinical diagnosis was ORN in eight, five of whom had clinical factors which suggested infection could have played a contributory role, and osteomyelitis in one patient. All patients had undergone additional radiotherapy treatment comprising of brachytherapy (7), stereotactic radiotherapy (1) or radiotherapy boost (2) and three had undergone nasopharyngectomy. Conclusion: ORN of the upper cervical spine following radiotherapy for NPC is more common than previously suspected and is seen in patients with additional treatment, especially brachytherapy. MRI features are often atypical and a contributory role of infection in the development of some cases of ORN is postulated.

    The study objectives were: to investigate current cervical spine radiographic imaging practices in conscious adult patients with suspected neck injury; reasons behind variation and consideration of dose estimates were explored. Comparison with a previous survey has been made. Questionnaires were sent to superintendent radiographers responsible for accident and emergency X-ray departments in English trusts with over 8500 emergency admissions per year, with a response rate of 97% (n = 181/186). Departmental cervical spine imaging protocols were reported by 82% of respondents. None use fewer than the three standard projections; if the cervicothoracic junction (C7/T1), is not adequately demonstrated 87% use swimmers projections, 9% supine obliques, 3% CT alone. Following projectional radiography, 97% perform CT. A significant (p = 0.018) increase was found since 1999 in CT use once the swimmers projection fails; fewer now use obliques at this point, continuing with CT instead. No significant difference (p = 0.644) was found in choice of first supplementary radiographs; despite British Trauma Society's recommendation to undertake supine obliques, swimmers remain the most widespread technique. An 85% response rate (n = 103/121) completed a second questionnaire, exploring reasons behind the various practices. Several reported a perceived difficulty in interpreting oblique radiographs, some a concern over high dose of the swimmers. Numerous issues affect the acquisition of cervical spine radiographs. Patient radiation dose should be a major consideration in selection of technique. A potential need for training in interpretation of obliques is highlighted. Specific guidelines for optimum projections should be researched, and protocols issued to ensure best practice.

    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.

    Full Text Available Bacground/Aim. Diagnostic protocol for patients with degenerative diseases of the cervical spine demands, in parallel with neuroimaging methods, functional evaluation through neurophysiological methods (somatosensitive and motor evoked potentials and electromyoneurography aiming to evaluate possible subclinical affection of spinal medula resulting in neurological signs of long tract abnormalities. Considering diversities of clinical outcomes for these patients, complex diagnostic evaluation provides a prognosis of the disease progression. Methods. The study included 21 patients (48.24 ± 11.01 years of age with clinical presentation of cervical spondylarthropathy, without neuroradiological signs of myelopathy. For each patient, in addition to conventional neurophysiological tests (somatisensory evoked potentials - SSEP, motor evoked potentials - MEP, electromyoneurography - EMG, nerve conduction studies, we calculated central motor conduction time (CMCTF, as well the same parameter in relation to a different position of the head (maximal anteflexion and retroflexion, so-called dynamic tests. Results. Abnormalities of the peripheral motor neurone by conventional EMNeG was established in 2/3 of the patients, correponding to the findings of root condution time. Prolonged conventional CVMPF were found in 29% of the patients, comparing to 43% CVMPF abnormalities found with the dynamic tests. In addition, the SSEP findings were abnormal in 38% of the patients with degenerative diseases of the cervical spine. Conclusion. An extended neurophysiological protocol of testing corticospinal functions, including dynamic tests of central and periheral motor neurons are relevant for detection of subclinical forms of cervical spondylothic myelopathy, even at early stages. In addition to the conventional neurophysiological tests, we found usefull to include the dynamic motor tests and root conduction time measurement in diagnostic evaluation.

    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.

    The primary aim of this study was to conduct a systematic review of reports of patients with cervical spondylotic myelopathy and to assess the value of intraoperative monitoring (IOM), including somatosensory evoked potentials, transcranial motor evoked potentials and electromyography, in anterior cervical procedures. A search was conducted to collect a small database of relevant papers using key words describing disorders and procedures of interest. The database was then shortlisted using selection criteria and data was extracted to identify complications as a result of anterior cervical procedures for cervical spondylotic myelopathy and outcome analysis on a continuous scale. In the 22 studies that matched the screening criteria, only two involved the use of IOM. The average sample size was 173 patients. In procedures done without IOM a mean change in Japanese Orthopaedic Association score of 3.94 points and Nurick score by 1.20 points (both less severe post-operatively) was observed. Within our sub-group analysis, worsening myelopathy and/or quadriplegia was seen in 2.71% of patients for studies without IOM and 0.91% of patients for studies with IOM. Variations persist in the existing literature in the evaluation of complications associated with anterior cervical spinal procedures. Based on the review of published studies, sufficient evidence does not exist to make recommendations regarding the use of different IOM modalities to reduce neurological complications during anterior cervical procedures. However, future studies with objective measures of neurological deficits using a specific IOM modality may establish it as an effective and reliable indicator of injury during such surgeries.

    Cervical spinal cord dysfunction can result from either traumatic or nontraumatic causes, including tumors, infections, and degenerative changes. In this article, we review the range of degenerative spinal disorders resulting in progressive cervical spinal cord compression and propose the adoption of a new term, degenerative cervical myelopathy (DCM). DCM comprises both osteoarthritic changes to the spine, including spondylosis, disk herniation, and facet arthropathy (collectively referred to as cervical spondylotic myelopathy), and ligamentous aberrations such as ossification of the posterior longitudinal ligament and hypertrophy of the ligamentum flavum. This review summarizes current knowledge of the pathophysiology of DCM and describes the cascade of events that occur after compression of the spinal cord, including ischemia, destruction of the blood-spinal cord barrier, demyelination, and neuronal apoptosis. Important features of the diagnosis of DCM are discussed in detail, and relevant clinical and imaging findings are highlighted. Furthermore, this review outlines valuable assessment tools for evaluating functional status and quality of life in these patients and summarizes the advantages and disadvantages of each. Other topics of this review include epidemiology, the prevalence of degenerative changes in the asymptomatic population, the natural history and rates of progression, risk factors of diagnosis (clinical, imaging and genetic), and management strategies.

    Multiple factors contribute to the determination for surgical intervention in the setting of cervical spinal injury, yet to date no unified classification system exists that predicts this need. The goals of this study were twofold: to create a comprehensive subaxial cervical spine injury severity numeric scoring model, and to determine the predictive value of this model for the probability of surgical intervention. In a retrospective cohort study of 333 patients, neural impairment, patho-morphology, and available spinal canal sagittal diameter post-injury were selected as injury severity determinants. A common numeric scoring trend was created; smaller values indicated less favorable clinical conditions. Neural impairment was graded from 2-10, patho-morphology scoring ranged from 2-15, and post-injury available canal sagittal diameter (SD) was measured in millimeters at the narrowest point of injury. Logistic regression analysis was performed using the numeric scores to predict the probability for surgical intervention. Complete neurologic deficit was found in 39 patients, partial deficits in 108, root injuries in 19, and 167 were neurologically intact. The pre-injury mean canal SD was 14.6 mm; the post-injury measurement mean was 12.3 mm. The mean patho-morphology score for all patients was 10.9 and the mean neurologic function score was 7.6. There was a statistically significant difference in mean scores for neural impairment, canal SD, and patho-morphology for surgical compared to nonsurgical patients. At the lowest clinical score for each determinant, the probability for surgery was 0.949 for neural impairment, 0.989 for post-injury available canal SD, and 0.971 for patho-morphology. The unit odds ratio for each determinant was 1.73, 1.61, and 1.45, for neural impairment, patho-morphology, and canal SD scores, respectively. The subaxial cervical spine injury severity determinants of neural impairment, patho-morphology, and post-injury available canal SD have

    Myelographic and MRI results in 14 patients treated in 1992 because of cervical spine injury with neurological complications have been presented. Myelography proves to be useful in posttraumatic spine diagnostics but in some cases does not render sufficient information, especially if the trauma superimposes previously existing pathological changes. MRI is exceptionally valuable diagnostic modality in cervical spine injuries offering an advantage of both early and late evaluation of the post-traumatic spinal cord changes.

    Introduction: The aim of this review was to investigate whether Flexion/Extension (F/E) radiography adds diagnostic value to CT or MRI in the detection of cervical spine ligamentous injury and/or clinically significant cervical spine instability of blunt trauma patients. Methods: A systematic search of literature was done in Pubmed, Embase and Cochrane Library databases. Primary outcome was sensitivity and specificity of F/E radiography. Secondary outcomes were the positive predicting value (PPV) and negative predicting value (NPV) (with CT or MRI as reference tests due to the heterogeneity of the included studies) of each modality and the quality of F/E radiography. Results: F/E radiography was overall regarded to be inferior to CT or MRI in the detection of ligamentous injury. This was reflected by the high specificity and NPV for CT with F/E as reference test (ranging from 97 to 100% and 99 to 100% respectively) and the ambiguous results for F/E radiography with MRI as its reference test (0–98% and 0–83% for specificity and NPV respectively). Image quality of F/E radiography was reported to have 31 to 70% adequacy, except in two studies which reported an adequacy of respectively 4 and 97%. Conclusion: This systematic review of the literature shows that F/E radiography adds little diagnostic value to the evaluation of blunt trauma patients compared to CT and MRI, especially in those cases where CT or MRI show no indication of ligamentous injury.

    Full Text Available The SLICS (Sub-axial Cervical Spine Injury Classification System was proposed to help in the decision-making of sub-axial cervical spine trauma (SCST, even though the literature assessing its safety and efficacy is scarce. Method We compared a cohort series of patients surgically treated based on surgeon’s preference with patients treated based on the SLICS. Results From 2009-10, 12 patients were included. The SLICS score ranged from 2 to 9 points (mean of 5.5. Two patients had the SLICS < 4 points. From 2011-13, 28 patients were included. The SLICS score ranged from 4 to 9 points (mean of 6. There was no neurological deterioration in any group. Conclusion After using the SLICS there was a decrease in the number of patients with less severe injuries that were treated surgically. This suggests that the SLICS can be helpful in differentiating mild from severe injuries, potentially improving the results of treatment.

    Full Text Available Abstract Introduction Non-Hodgkin lymphoma primarily originating from the bone is exceedingly rare. To our knowledge, this is the first report of primary bone lymphoma presenting with progressive cord compression from an origin in the cervical spine. Herein, we discuss the unusual location in this case, the presenting symptoms, and the management of this disease. Case presentation We report on a 23-year-old Caucasian-American man who presented with two months of night sweats, fatigue, parasthesias, and progressive weakness that had progressed to near quadriplegia. Magnetic resonance (MR imaging demonstrated significant cord compression seen primarily at C7. Surgical management, with corpectomy and dorsal segmental fusion, in combination with adjuvant chemotherapy and radiation therapy, halted the progression of the primary disease and preserved neurological function. Histological analysis demonstrated an aggressive anaplastic large cell lymphoma. Conclusion Isolated primary bony lymphoma of the spine is exceedingly rare. As in our case, the initial symptoms may be the result of progressive cervical cord compression. Anterior corpectomy with posterolateral decompression and fusion succeeded in preventing progressive neurologic decline and maintaining quality of life. The reader should be aware of the unique presentation of this disease and that surgical management is a successful treatment strategy.

    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 Background and Aims: Literature suggests that glottic view is better when using McGrath® Video laryngoscope and Truview® in comparison with McIntosh blade. The purpose of this study was to evaluate the effectiveness of McGrath Video laryngoscope in comparison with Truview laryngoscope for tracheal intubation in patients with simulated cervical spine injury using manual in-line stabilisation. Methods: This prospective randomised study was undertaken in operation theatre of a tertiary referral centre after approval from the Institutional Review Board. A total of 100 consenting patients presenting for elective surgery requiring tracheal intubation were randomly assigned to undergo intubation using McGrath® Video laryngoscope (n = 50 or Truview® (n = 50 laryngoscope. In all patients, we applied manual-in-line stabilisation of the cervical spine throughout the airway management. Statistical testing was conducted with the statistical package for the social science system version SPSS 17.0. Demographic data, airway assessment and haemodynamics were compared using the Chi-square test. A P < 0.05 was considered significant. Results: The time to successful intubation was less with McGrath video laryngoscope when compared to Truview (30.02 s vs. 38.72 s. However, there was no significant difference between laryngoscopic views obtained in both groups. The number of second intubation attempts required and incidence of complications were negligible with both devices. Success rate of intubation with both devices was 100%. Intubation with McGrath Video laryngoscope caused lesser alterations in haemodynamics. Conclusions: Both laryngoscopes are reliable in case of simulated cervical spine injury using manual-in-line stabilisation with 100% success rate and good glottic view.

  19. Significance of magnetic resonance imaging in the diagnosis of vertebral artery injury associated with blunt cervical spine trauma

    International Nuclear Information System (INIS)

    Vertebral artery injury associated with non-penetrating cervical trauma is rare. We report 11 cases of vertebral artery injury diagnosed with magnetic resonance imaging (MRI) after blunt trauma to the cervical spine and discuss about the importance of MRI in the diagnosis of this injury. Seven cases were caused by motor vehicle accidents, three by diving accidents, and one by static compression of the neck. All of the patients had documented cervical spine fractures and dislocations. In three patients, the diagnosis of complete occlusion of the vertebral artery was made on the basis of MRI and digital subtraction angiography (DSA). In the other patients, mural injuries of the vertebral artery were demonstrated with DSA. These 11 patients presented with acute, nonspecific changes in neurological status. Two had infarctions of the cerebellum and brainstem. None were treated with anticoagulants. All of them survived and were discharged to other hospitals for physical and occupational therapy. Although DSA remains the gold standard for diagnosing vertebral artery injuries, MRI is a newer modality for assessing cervical cord injury, and it may be useful for evaluating the presence of vertebral injury after blunt cervical spine trauma.

    Full Text Available Abstract Introduction Even if performed by qualified physical therapists, spinal manipulation and mobilization can cause adverse events. This holds true particularly for the cervical spine. In light of the substantial risks, the benefits of cervical spine manipulation may be outweighed by the possibility of further injury. Case presentation We present the case of a 56-year-old Caucasian man with Forestier's disease who went to see a physiotherapist to relieve his aching neck while on a holiday trip. Following the procedure, he was transferred to a local hospital with a partial tetraplegic syndrome due to a cervical 6/7 luxation fracture. Reportedly, the physiotherapist took neither a detailed history, nor adequate diagnostic measures. Conclusions This case highlights the potentially dangerous complications associated with cervical spine mobilization/manipulation. If guidelines concerning cervical spine mobilization and manipulation practices had been followed, this adverse event could have been avoided.

  1. Usefulness of MRI detection of cervical spine and brain injuries in the evaluation of abusive head trauma

    International Nuclear Information System (INIS)

    In the evaluation of children younger than 3 years with intracranial hemorrhage it can be difficult to determine whether the cause of hemorrhage was traumatic, and if so, whether abusive head trauma (AHT) is a possibility. Cervical spine MRI is not a routine part of the nationally recommended imaging workup for children with suspected abusive head trauma. There is increasing evidence that spinal injuries are found at autopsy or MRI in abused children. However the prevalence of cervical spine injuries in children evaluated for abusive head trauma is unknown. We sought to determine both the incidence and the spectrum of cervical spine and brain injuries in children being evaluated for possible abusive head trauma. We also examined the relationship between cervical and brain MRI findings and selected study outcome categories. This study is a 3-year retrospective review of children evaluated for abusive head trauma. Inclusion criteria were: children with head trauma seen at our institution between 2008 and 2010, age younger than 36 months, availability of diagnostic-quality brain and cervical spine MRI, and child abuse team involvement because abusive head trauma was a possibility. A child abuse pediatrician and pediatric radiologists, all with board certification, were involved in data collection, image interpretation and data analysis. Statistical analysis was performed using Stata v12.1. The study included 74 children (43 boys, 31 girls) with a mean age of 164 days (range, 20-679 days). Study outcomes were categorized as: n = 26 children with accidental head trauma, n = 38 with abusive head trauma (n = 18 presumptive AHT, n = 20 suspicious for AHT), and n = 10 with undefined head trauma. We found cervical spine injuries in 27/74 (36%) children. Most cervical spine injuries were ligamentous injuries. One child had intrathecal spinal blood and two had spinal cord edema; all three of these children had ligamentous injury. MRI signs of cervical injury did not show a

    Assessing degenerative disease in the cervical spine remains a challenge. There is much controversy about imaging the cervical spine using MRI. Our aim in this prospective study was to compare a T2*-weighted 2D spoiled gradient-echo multiecho sequence (MEDIC) with a magnetisation transfer saturation pulse with cervical myelography and postmyelographic CT. Using an assessment scale we looked at the vertebral bodies, intervertebral discs, neural foramina, anterior and posterior nerve roots, grey matter, ligamenta flava, oedema in the spinal cord and stenosis of the spinal canal. We also evaluated postmyelography CT and the MEDIC sequence for assessing narrowing of the neural foramina in a cadaver cervical spine. We examined 67 disc levels in 18 patients, showing 18 disc prolapses and 21 osteophytes narrowing the spinal canal or the neural foramina. All MRI studies showed these abnormalities findings equally well. Postmyelography CT was significantly better for showing the bony structures and the anterior and posterior nerve roots. The MEDIC sequence provided excellent demonstration of soft-tissue structures such as the intervertebral disc and ligamentum flavum. No statistical differences between the imaging modalities were found in the assessment of narrowing of the neural foramina or the extent of spinal stenosis. The cadaver measurements showed no overestimation of abnormalities using the MEDIC sequence. (orig.)

    Full Text Available Background: Early cervical spine clearance is extremely important in unconscious trauma patients and may be difficult to achieve in emergency setting. Objectives: The aim of this study was to assess the feasibility of standard portable ultrasound in detecting potentially unstable cervical spine injuries in severe traumatic brain injured (TBI patients during initial resuscitation. Materials and Methods: This retro-prospective pilot study carried out over 1-month period (June-July 2013 after approval from the institutional ethics committee. Initially, the technique of cervical ultrasound was standardized by the authors and tested on ten admitted patients of cervical spine injury. To assess feasibility in the emergency setting, three hemodynamically stable pediatric patients (≦18 years with isolated severe head injury (Glasgow coma scale ≤8 coming to emergency department underwent an ultrasound examination. Results: The best window for the cervical spine was through the anterior triangle using the linear array probe (6-13 MHz. In the ten patients with documented cervical spine injury, bilateral facet dislocation at C5-C6 was seen in 4 patients and at C6-C7 was seen in 3 patients. C5 burst fracture was present in one and cervical vertebra (C2 anterolisthesis was seen in one patient. Cervical ultrasound could easily detect fracture lines, canal compromise and ligamental injury in all cases. Ultrasound examination of the cervical spine was possible in the emergency setting, even in unstable patients and could be done without moving the neck. Conclusions: Cervical ultrasound may be a useful tool for detecting potentially unstable cervical spine injury in TBI patients, especially those who are hemodynamically unstable.

    Clinical observations suggest the need for changing therapeutic management to a more active one in cases of cervical spine injury with damage to the spinal cord and nerve roots or brachial plexus. In 248 patients with these injuries treated initially conservatively the incidence of cervicobrachial pain was analysed. Neuralgic pains were present in 31.5% of cases, causalgic pains in 2.4% and sympathalgic pains in 2%. Conservative treatment conducted in these patients (89 cases) during many months after trauma had no effect on return of mobility. Long-term application of physioterapy prevented only temporarily the development of trophic changes and only partially relieved pains. Only surgical decompression of the spinal cord or spinal nerves with stabilization of damaged vertebrae caused disappearance of painful syndromes and improvement in the motor activity of the extremities. These observations show that early surgical intervention for decompression of the spinal cord, roots or brachial plexus should be advocated in these cases.

    Full Text Available This study characterized the normal musculoskeletal anatomy of the cervical segment of the spine of dogs by means of B-mode ultrasonography. The objective was to establish the role of B-mode ultrasonography for the anatomical evaluation of the cervical spine segment in dogs, by comparing the ultrasonographic findings with images by computed tomography and magnetic resonance imaging. The ultrasound examination, in transverse and median sagittal sections, allowed to identify a part of the epaxial cervical musculature, the bone surface of the cervical vertebrae and parts of the spinal cord through restricted areas with natural acoustic windows, such as between the atlanto-occipital joint, axis and atlas, and axis and the third cervical vertebra. The images, on transverse and sagittal planes, by low-field magnetic resonance imaging, were superior for the anatomical identification of the structures, due to higher contrast between the different tissues in this modality. Computed tomography showed superiority for bone detailing when compared with ultrasonography. As for magnetic resonance imaging, in addition to the muscles and cervical vertebrae, it is possible to identify the cerebrospinal fluid and differentiate between the nucleus pulposus and annulus fibrosus of the intervertebral discs. Although not the scope of this study, with knowledge of the ultrasonographic anatomy of this region, it is believed that some lesions can be identified, yet in a limited manner, when compared with the information obtained mainly with magnetic resonance imaging. The ultrasound examination presented lower morphology diagnostic value compared with the other modalities.

    A chronological review of damage to the spine and upper extremities associated with work was carried out in a sample of 120 retired disabled workers. Examination of risk factors for cervicobrachial syndrome (CBS) showed that the forced, bent position of the body at work contributed significantly to the frequency of the disease, particularly in women (70.0% against 38% in controls P less than 0.01). The lifting of heavy loads was also frequently observed in women with CBS (12% compared to 6% in the control group (P less than 0.05). Repeated movements during work were claimed by 52.9% of the males and 80% of the females with CBS and by only 41.4% of the males and 50% of the females without it (P less than 0.01). The heaviest load lifted by subjects with CBS at work exceeded significantly that of control subjects. It is considered that there is a causal link between excessive burden and the occurrence of CBS in women. For early diagnosis of CBS, tiredness, pain in the cervical spine, reduced strength in the hands and poor ability to endure manual work are signs to be looked for. Early recognition of disease, improved working conditions and recreation can help prevent the disease or slow down its progress. PMID:2637664

    We present the operative technique employed in a young man with cervical spine luxation at the level of C6-C7 with clinical signs of damage to the spinal cord at the level of C5. In order to achieve an optimal therapeutic effect (decompression of neural structures and spinal stabilisation) during one surgical procedure, the positioning of the patient was changed twice during the procedure. Considering the positioning of the patient at the beginning of the procedure, the body position was changed by 360 degrees. The first part of the procedure was performed from an anterior approach with the patient in the supine position. It involved a C6-C7 discectomy and removal of the upper surface of the body of C7, which was protruding into the vertebral canal and compressing the spinal cord. Intraoperative inspection showed that a posterior approach was necessary to reduce the luxation. Therefore, for the second part of the operation, the patient was turned by 180 degrees and placed in the prone position. For the last (third) part of the surgical procedure, the patient was again turned by 180 degrees and placed in the supine position in order to insert an anterior spine fixator. We believe that a procedure utilising different surgical approaches and different positioning of the patient in order to achieve optimal therapeutic effect may be used in selected cases in everyday clinical practice.

  10. Multirigid registration of MR and CT images of the cervical spine

    Hu, Yangqiu; Haynor, David R.

    2004-05-01

    We present our work on fusion of MR and CT images of the cervical spine. To achieve the required registration accuracy of approximately 1mm, the spine is treated as a collection of rigid vertebrae, and a separate rigid body transformation applied to each (Hawkes). This in turn requires segmentation of the CT datasets into separate vertebral images, which is difficult because the narrow planes separating adjacent vertebrae are parallel to the axial plane of the CT scans. We solve this problem by evolving all the vertebral contours simultaneously using a level set method, and use contour competition to estimate the position of the vertebral edges when a clean separation between adjacent vertebrae is not seen. Contour competition is based in turn on the vertical scan principle: no part of a given vertebra is vertically below any part of an inferior vertebra. Once segmentation is complete, the individual rigid body transforms are then estimated using mutual information maximization, and the CT images of the vertebrae superimposed on the MR scans. The resultant fused images contain the bony detail of CT and the soft tissue discrimination of MR and appear to be diagnostically equivalent, or superior, to CT myelograms. A formal test of these conclusions is planned for the next phase of our work.

    Background and Importance Primary leptomeningeal melanoma (PLM) is highly malignant and exceedingly rare. Due to its rarity, diagnostic and treatment paradigms have been slow to evolve. We report the first case of a PLM that mimics a cervical spine meningioma and then discuss the current clinical, radiologic, and pathologic diagnostic methodologies as well as expected outcomes related to this disease. Clinical Presentation A 54-year-old woman presented a dural-based extramedullary solid mass ventral to the C2-C3 spinal cord causing spinal cord compression without cord signal changes, characteristic of meningioma. Intraoperative microscopic inspection revealed numerous black spots littering the surface of the dura; the tumor itself was yellow in appearance and had a soft consistency. Pathologic analysis of the specimen revealed a malignant melanin-containing tumor. No primary site was found, so a diagnosis of primary leptomeningeal melanoma was made, and the patient subsequently received interferon therapy. To date (2 years postoperatively), no local or systemic recurrence of the tumor has been identified. Conclusion As with most rare tumors, case reports constitute the vast majority of references to PLM. Only an increased awareness and an extensive report of each individual case can help diagnose and clarify the nature of PLM. Clinicians need to be aware of such malignant conditions when diagnosing benign tumoral lesions of the spine such as meningiomas.

    2015-03-01

    Full Text Available Introduction: Although perforation of the esophagus, in the anterior cervical spine fixation, is well established, cases with delayed onset, especially cases that present pseudodiverticulum, are not common. In addition, management of the perforation in this situation is debated.  Case Report:   Delayed esophageal pseudodiverticulum was managed in two patients with a history of anterior spine fixation. Patients were operated on, the loose plate and screws were extracted, the wall of the diverticulum was excised, the perforation on the nasogastric tube was suboptimally repaired, and a closed suction drain was placed there. The NGT was removed on the 7th day and barium swallow demonstrated no leakage at the operation site; therefore, oral feeding was started without any problem.  Conclusion:  In cases with delayed perforation, fistula, or diverticulum removal of anterior fixation instruments, gentle repair of the esophageal wall without persistence on definitive and optimal perforation closure, wide local drainage, early enteral nutrition via NGT, and antibiotic prescription is suggested.

    Full Text Available Introduction: The National Emergency X-radiography Utilization Study (NEXUS criteria are used extensively in emergency departments to rule out C-spine injuries (CSI in the general population. Although the NEXUS validation set included 2,943 elderly patients, multiple case reports and the Canadian C-Spine Rules question the validity of applying NEXUS to geriatric populations. The objective of this study was to validate a modified NEXUS criteria in a low-risk elderly fall population with two changes: a modified definition for distracting injury and the definition of normal mentation. Methods: This is a prospective, observational cohort study of geriatric fall patients who presented to a Level I trauma center and were not triaged to the trauma bay. Providers enrolled non-intoxicated patients at baseline mental status with no lateralizing neurologic deficits. They recorded midline neck tenderness, signs of trauma, and presence of other distracting injury. Results: We enrolled 800 patients. One patient fall event was excluded due to duplicate enrollment, and four were lost to follow up, leaving 795 for analysis. Average age was 83.6 (range 65-101. The numbers in parenthesis after the negative predictive value represent confidence interval. There were 11 (1.4% cervical spine injuries. One hundred seventeen patients had midline tenderness and seven of these had CSI; 366 patients had signs of trauma to the face/neck, and 10 of these patients had CSI. Using signs of trauma to the head/neck as the only distracting injury and baseline mental status as normal alertness, the modified NEXUS criteria was 100% sensitive (CI [67.9-100] with a negative predictive value of 100 (98.7-100. Conclusion: Our study suggests that a modified NEXUS criteria can be safely applied to low-risk elderly falls.

  16. Inertial sensor real-time feedback enhances the learning of cervical spine manipulation: a prospective study

    Science.gov (United States)

    2014-01-01

    Background Cervical Spinal Manipulation (CSM) is considered a high-level skill of the central nervous system because it requires bimanual coordinated rhythmical movements therefore necessitating training to achieve proficiency. The objective of the present study was to investigate the effect of real-time feedback on the performance of CSM. Methods Six postgraduate physiotherapy students attending a training workshop on Cervical Spine Manipulation Technique (CSMT) using inertial sensor derived real-time feedback participated in this study. The key variables were pre-manipulative position, angular displacement of the thrust and angular velocity of the thrust. Differences between variables before and after training were investigated using t-tests. Results There were no significant differences after training for the pre-manipulative position (rotation p = 0.549; side bending p = 0.312) or for thrust displacement (rotation p = 0.247; side bending p = 0.314). Thrust angular velocity demonstrated a significant difference following training for rotation (pre-training mean (sd) 48.9°/s (35.1); post-training mean (sd) 96.9°/s (53.9); p = 0.027) but not for side bending (p = 0.521). Conclusion Real-time feedback using an inertial sensor may be valuable in the development of specific manipulative skill. Future studies investigating manipulation could consider a randomized controlled trial using inertial sensor real time feedback compared to traditional training. PMID:24942483

    Aim: (1) to establish which modality offers the greatest accuracy in the detection of cervical spine injury (CSI) Following trauma: plain radiography or computed tomography (CT), and (2) make an evidence-based recommendation for the initial imaging modality of choice. Method: A systematic literature review was performed to identify primary research studies which compare the diagnostic accuracy of plain radiography and CT with the results of a reference standard in the detection of CSI. A search of MEDLINE, EMBASE, CINAHL, Science Direct and Pubmed Central databases was conducted. Results: Ten studies were identified. Critical appraisal identified limitations among all studies. There was heterogeneity in the sensitivity estimates for plain radiography, whereas estimates for CT were consistently high. Examination of the reported sensitivities shows that CT outperforms plain radiography in the detection of CSI. Conclusion: CT is superior to plain radiography in the detection of CSI. However, the optimal imaging strategy depends on the patients' relative risk of injury. If at high-risk cervical CT is indicated. If at low-risk the increased cost and radiation exposure mean that screening CT may not be warranted, good-quality plain radiographs are sufficient.

    Blunt cerebrovascular injuries (BCVI) are associated with high morbidity and mortality and can lead to neurological deficits. The established criteria for patients undergoing CT angiography (CTA) for BCVI are broad, and can expose patients to radiation unnecessarily. This study aimed to examine the prevalence of BCVI in patients on CTA and determine presentations associated with the highest rates of BCVI. With IRB approval, patients were selected for CTA screening for BCVI according to a predefined set of criteria at our hospital between 2007 and 2010. Patients were identified from our institution's trauma database. CTAs were retrospectively reviewed for BCVI including vasospasm and dissection. Electronic medical records were reviewed for clinical presentation and hospital course. Of 432 patients, vasospasm (n = 10) and/or dissection (n = 36) were found in 46 patients (10.6 %). BCVI was associated with cervical spine and/or skull-base fracture in 40/46 patients (87 %, P < 0.0001). Significant correlations were seen between dissection and fracture in 31/36 patients (86.2 %, p < 0.0001) and between BCVI and both neurological deficits and fractures (27/44, P < 0.0001). BCVI was significantly associated with cervical and/or skullbase fractures and neurological deficits with coexistent fractures. Patients with these injuries should be prioritized for rapid CTA evaluation for BCVI. (orig.)

    In the article we review the current role of diffusion tensor imaging (DTI), a modern magnetic resonance (MR) technique, in the diagnosis and the management of cervical spondylotic myelopathy (CSM), the most serious complication of degenerative cervical spine disease (DCSD). The pathogenesis of DCSD is presented first with an emphasis placed on the pathological processes leading to myelopathy development. An understanding of the pathophysiological background of DCSD is necessary for appropriate interpretation of MR images, both plain and DTI. Conventional MRI is currently the imaging modality of choice in DCSD and provides useful information concerning the extent of spondylotic changes and degree of central spinal canal stenosis; however its capability in myelopathy detection is limited. DTI is a state of the art imaging method which recently has emerged in spinal cord investigations and has the potential to detect microscopic alterations which are beyond the capability of plain MRI. In the article we present the physical principles underlying DTI which determine its sensitivity, followed by an overview of technical aspects of DTI acquisition with a special consideration of spinal cord imaging. Finally, the scientific reports concerning DTI utility in DSCD are also reviewed. DTI detects spinal cord injury in the course of DCSD earlier than any other method and could be useful in predicting surgical outcomes in CMS patients, however technical and methodology improvement as well as standardization of acquisition protocols and postprocessing methods among the imaging centers are needed before its implementation in clinical practice.

    To discuss the pathological characteristics of cervical spinal fracture complicating ankylosing spondyli-tis-(AS) and the effect of combined anterior and posterior operation. Methods: Eighteen AS patients with traumatic cervical fracture-dislocation were treated operatively from January 2000 to January 2006. The symptom duration of AS was 14.5 years on average. Three cases had undergone osteotomy in lumbar spine. There were 4 cases of Grade A, 3 cases of Grade B, 9 cases of Grade C and 2 cases of Grade D accord-ing to Frankel's score. There were 15 cases of Grade Ⅲ dislocation and 3 cases of Grade Ⅱ. All patients underwent surgical procedures by combined anterior and posterior approach.Results: There were 4 anterior-posterior procedures, 8 anterior-posterior-anterior procedures and 6 posterior-an-terior procedures. Seven patients had one stage operation and 11 cases underwent two stage surgeries. There was certain extent of neorological improvement in 14 incomplete paraplegic patients, but no improvement in 4 complete paraplegic patients. The follow-up period was 21.2 months on average and the time for bone fusion was 3.6 months. There were 4 complications during operation and a long-term complication in follow-up. Conclusions: The study suggests that anterior com-bined with posterior approach makes the spine stable and relieves the pressure immediately. It is a reasonable surgical strategy for treatment of cervical spinal fracture-dislocation with AS.

    Conclusions: Our results reinforce the relationship between preoperative nutritional status and outcomes in elective spine surgery. The data indicate that preoperative prealbumin levels may be useful in risk stratification. Further study is needed to determine whether nutritional supplementation may reduce the risk of infection.

    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. PMID:27026564

    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.

    Objective To evaluate the clinical outcomes of surgical therapy in treating traumatic instability of subaxial cervical spine through either anterior or posterior approach. Methods according to the allen-Fergurson's classification, we retrospectively studied 42 cases of traumatic instability of subaxial cervical spine through either anterior or posterior surgical reconstruction. Patients requiring approach for either reduction or decompression were not included.Results The average follow-up interval was 3 years and 2 months. The anterior and posterior reconstructions were 24 and 18 cases, respectively. Before operation, the average scores of JOA and VAS were: 12.1 and 6.9 for anterior group, and 12.3 and 7.2 for posterior group. At the final assement, the scores of JOA and VAS improved to 16.0 and 2.2 for anterior group, and 15.7 and 2.6 for posterior group. The average ASIA motor scores of anterior and posterior group improved to 68.2 and 65.5 at the final follow-up from 58.4 and 59.7 before operation, respectively. The ASIA grade (A-E) was converted to a numeric score. The average scores before operation in the anterior and posterior group were 3.3 and 3.4, and increased to 3.8 and 3.7 at the final follow-up. After operation, there were different extent improvements of average radiological parameter, such as Cobb angle, vertebral body translation and disc height ratio. The average operation time and blood losing were 122 min and 125 mL for anterior group, and 153 min and 287 mL for posterior group. Fusion was achieved in all patients and 4 and 2 complications occurred at the anterior or posterior group.Conclusion The results showed that there were no obvious difference in parameters, such as neurological assements, functional grades, fusion rate, operation time and blood losing, between anterior and posterior group, except the virtues of anterior group in reconstruction and maintaining physiologic cervical lordosis and intervertrbal disc height occurred.

    The aim of this case report was to highlight the application of magnetic resonance imaging (MRI) in elucidating serious and occult injuries in a single case of hyperflextion injury of a patient cervical spine (C-Spine). A chart and radiology review was performed to establish the sequence of care and how the results of imaging studies influenced the clinical management in this trauma case. Plain radiographs and computed tomography (CT) imaging modalities of the C-Spine revealed bilateral C4/C5 facetal subluxation with no obvious fractures; however, the MR imaging of the C-Spine revealed a non-contiguous and occult injury to C6/C7 disc with a posterior annular tear and associated disc extrusion. This altered the operative intervention that was initially planned. MR imaging proved an invaluable diagnostic addition in this particular case of cervical trauma in a rugby player following a hyperflextion injury, by revealing a serious non-contiguous and occult injury of the C-Spine.

    Nearly all children with MPS IVA develop skeletal deformities affecting the spine. At the atlanto-axial spine, odontoid hypoplasia occurs. GAG deposition around the dens, leads to peri-odontoid infiltration. Transverse/alar ligament incompetence causes instability. Atlanto-axial instability is associated with cord compression and myelopathy, leading to major morbidity and mortality. Intervention is often required. Does the presence of widened bullet shaped vertebra in platyspondily encroach on the spinal canal and cause spinal stenosis in MPS IVA? So far, there have been no standardised morphometric measurements of the paediatric MPS IVA cervical spine to evaluate whether there is pre-existing spinal stenosis predisposing to compressive myelopathy or whether this is purely an acquired process secondary to instability and compression. This study provides the first radiological quantitative analysis of the cervical spine and spinal cord in a series of affected children. MRI morphometry indicates that the MPS IVA spine is narrower at C1-2 level giving an inverted funnel shape. There is no evidence of a reduction in the Torg ratio (canal-body ratio) in the cervical spine. The spinal canal does not exceed 11 mm at any level, significantly smaller than normal historical cohorts (14 mm). The sagittal diameter and axial surface area of both spinal canal and cord are reduced. C1-2 level cord compression was evident in the canal-cord ratio but the Torg ratio was not predictive of cord compression. In MPS IVA the reduction in the space available for the cord (SAC) is multifactorial rather than due to congenital spinal stenosis. PMID:23404316

    2016-01-01

    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.

    OBJECTIVE The accuracy of public reporting in health care is an issue of debate. The authors investigated the association of patient satisfaction measures from a public reporting platform with objective outcomes for patients undergoing spine surgery. METHODS The authors performed a cohort study involving patients undergoing elective spine surgery from 2009 to 2013 who were registered in the New York Statewide Planning and Research Cooperative System database. This cohort was merged with publicly available data from the Centers for Medicare and Medicaid Services (CMS) Hospital Compare website. A mixed-effects regression analysis, controlling for clustering at the hospital level, was used to investigate the association of patient satisfaction metrics with outcomes. RESULTS During the study period, 160,235 patients underwent spine surgery. Using a mixed-effects multivariable regression analysis, the authors demonstrated that undergoing elective spine surgery in hospitals with a higher percentage of patient-assigned high satisfaction scores was not associated with a decreased rate of discharge to rehabilitation (OR 0.77, 95% CI 0.57-1.06), mortality (OR 0.96, 95% CI 0.90-1.01), or hospitalization charges (β 0.04, 95% CI -0.16 to 0.23). However, it was associated with decreased length of stay (LOS; β -0.19, 95% CI -0.33 to -0.05). Similar associations were identified for hospitals with a higher percentage of patients who claimed they would recommend these institutions to others. CONCLUSIONS Merging a comprehensive all-payer cohort of spine surgery patients in New York state with data from the CMS Hospital Compare website, the authors were not able to demonstrate an association of improved performance in patient satisfaction measures with decreased mortality, rate of discharge to rehabilitation, and hospitalization charges. Increased patient satisfaction was associated with decreased LOS. PMID:26989975

  12. Study on pedicle screw fixation of cervical spine assisted CT-based navigation system compared with the individual cervical peddle screws placement technique

    International Nuclear Information System (INIS)

    Objective: To explore a safe and effective method for placing the cervical pedicle screws. Methods: There were ten adult cadaver specimens of cervica spine (C1-C7) with intact structures including ligament and perivertebral muscles. The spiral computed tomography scan (Elscint CT Twin flash) at the section of 1 mm and three-dimensional reconstruction of all 10 cervical specimens were taken. By CT scan, the parameters of the cervical pedicles were measure,Then taking randomly 5 cervical specimens, according to the CT measurements, an appropriate screw was inserted into pedicle individually. In the other 5 human cadaver cervical vertebraes, Φ3.5 mm screws were inserted into the C2-C7 pedicles by assisted by CT-based navigation system. Cortical integrity of every sample was examined by anatomic dissection, the spiral computed tomography scan and arrows,and coronal reconstruction. Results: Sixty screws was inserted into pedicle individually, and the achievement ratio was 90%, the perfectness ratio was 75%, 60 screws was placed into pedicle assisted by CT-based navigation system, and the achievement ratio was 96.6%, the perfectness ratio was 90%. By chi-square test for statistical analysis, there were no statistical significance between the accuracy rate of two methods(P>0.05). However there was statistical significance between the perfectness ratio between two methods(P<0.05). Conclusion: Compared with the individual cervical peddle screws placement technique, the perfectness ratio of pedicle screw fixation of cervical spine assisted by CT-based navigation system is higher, but there are no significant difference in accuracy.

    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

    Full Text Available Cervical spine injuries in Rugby Union are a concerning issue at all levels of the game. The primary aim of this retrospective analysis conducted in a professional Rugby Union squad was to determine whether a 26-week isometric neck strengthening intervention program (13-week strengthening phase and 13-week maintenance phase was effective in reducing the number and severity of cervical spine injuries. The secondary aim was to determine whether at week five, where the program had been the similar for all players, there was increased isometric neck strength. All 27 players who were common to both the 2007-2008 and 2008-2009 seasons were included in this analysis and data was extracted from a Sports Medicine/Sports Science database which included the squad's injury records. Primary outcome variables included; the number of cervical spine injuries and the severity of these injuries as determined by the total number of days lost from training and competition. Secondary outcome variables included isometric neck strength in flexion, extension and left and right lateral flexion. Using non-parametric statistical methods, no significant differences were evident for the total number of cervical spine injuries (n = 8 in 2007-2008, n = 6 in 2008-2009 or time loss due to these injuries (100 days in 2007-2008, 40 days in 2008-2009. However, a significant (p = 0.03 reduction in the number of match injuries was evident from 2007-2008 (n = 11 to 2008-09 (n = 2. Non-significant increases in isometric neck strength were found in all directions examined. A significant reduction in the number of match injuries was evident in this study. However, no other significant changes to primary outcome variables were achieved. Further, no significant increases in isometric neck strength were found in this well-trained group of professional athletes

    Heterotopic calcification following head and neck irradiation has rarely been reported. It usually develops as a late complication of radiotherapy in patients with malignancies, including breast cancer, lymphoma, and genitourinary malignancies. The occurrence of heterotopic calcification in the prevertebral space of the cervical spine has not been described as a late complication of irradiation. Here, we report a case of prevertebral heterotopic calcification in a patient with history of chemotherapy and radiotherapy for tonsil cancer 21 years ago.

    Static X-rays recorded at two planes from the cervical spine of 286 patients were evaluated and were compared to findings obtained from 50 probands without complaints. The patients complained about problems relating to vertebrogenic pain syndrome of the cervical spine, including vertigo of cervical origin. They were grouped by four sets of clinical symptoms (cephalgia, vertigo, locally delimited complaints and cervicobrachial syndrome). No statistically significant differences were found to exist among the groups of probands with regard to radiographic morphology, static condition nor impairment of relations. Particular reference is made in this paper to reversible function disorders and their major role among the multifactorial causes of the cervical syndrome. Indications are derived from these observations for primary X-ray examination of the cervical spine. (orig.).

    Full Text Available Background: Diagnosis of cervical spine injury (CSI is difficult in patients with an altered level of consciousness as a result of a traumatic brain injury (TBI. Patients with TBI and older adults are at increased risk for CSI. This study examined the various risk factors for CSI among trauma patients with TBI and whether adults who were older (≥55 years were at higher risk for CSI when they sustained a fall-related TBI. Materials and Methods: Data used was the 2007 National Trauma Data Bank (NTDB, National Sample Project (NSP for adults who sustained a TBI. This dataset contains 2007 admission records from 82 level I and II trauma centers. Logistic regression was used to identify potential risk factors for CSI and to test for interaction between age and injury mechanism. Additional model variables included gender, race, Glasgow Coma Score, multiple severe injuries, hypotension and respiratory distress. Results: An analysis of the NTDB NSP identified 187,709 adults with TBI, of which 16,078 were diagnosed with a concomitant CSI. In motor vehicle traffic injuries, the older age group had significantly higher odds of CSI (odds ratio [OR] = 1.26 [1.15-1.39]. In fall-related injuries the older age group did not have a higher odds of CSI compared to the younger age group. Skull/face fracture, other spine fracture/dislocation, upper limb injury, thorax injury, and hypotension were significantly associated with CSI. Pelvic injuries had an inverse association with CSI (OR = 0.60 [0.54-0.67]. Black had significantly higher odds of CSI compared to Whites (OR = 1.25 [1.07-1.46]. Conclusion: The identification of associated injuries and factors may assist physicians in evaluating CSI in patients with TBI.

  18. The ossification pattern in paediatric occipito-cervical spine: is it possible to estimate real age?

    International Nuclear Information System (INIS)

    Aim: To retrospectively analyse the synchondrosis from the occipital bone to the whole cervical spine and determine the feasibility and validity of age estimation using computed tomography (CT) images. Material and methods: A total of 231 cervical spine or neck CT images of young children (<7 years of age) were examined. Twelve ossification centres were assessed (occiput: n = 2; atlas: n = 2; axis, n = 6; whole sub-axial vertebra: n = 2), and the ossification process was graded as open (O, fully lucent), osseous bridging (B, partially ossified), and fusion (F, totally ossified). After the first analysis was completed, the resulting chronological chart was used to estimate the age of 10 new cases in order to confirm the usefulness of the chart. Results: Infancy was easily estimated using the sub-axial or C2 posterior ossification centres, while the posterior occipital regions provided good estimation of age between 1–2 years. The most difficult period for accurate age estimation was between 2–4 years. However, the C2 anterior (neurocentral ossification) and C1 posterior regions did yield information to help determine the age around 3 years. The anterior occipital region was useful for age estimation between 4–5 years, and the C1-anterior region was potentially useful to help decide among the other parameters. The test for age estimation (TAE) had a very high ICC score (0.973) among the three observers. Conclusion: Segmentalised analysis can enhance the ability to estimate real age, at least by the year. The analysis of the occipital bone made a strong contribution to the usefulness of the chorological chart. An organised chronological chart can provide readily available information for age estimation, and the primary application of the above data (TAE) demonstrated the validity of this approach. -- Highlights: •Subaxial or C2 posterior regions was useful for age estimation between 0–1 year. •Posterior occipital regions provided good estimation of

    To describe the radiographic features and progression of cervical spine destructive spondyloarthropathy (DSA) in hemodialyzed patients, and to evaluate the relationship between this disease and patient characteristics, biochemical values, and hemodialysis duration. Design and patients: Standard radiographs, and lateral flexion and extension views of the cervical spine, were performed annually for 5 years in 31 hemodialyzed patients who were divided into three groups at the commencement of the study: those showing (I) DSA, (II) vertebral rim erosions (VRE) without DSA, and (III) absence of DSA and VRE. Magnetic resonance (MR) imaging and computed tomography (CT) were performed in seven and two patients respectively. The imaging features were evaluated for the presence and progression of spondyloarthropathy and correlated with clinical and biochemical variables. Statistical analysis was performed using one-way analysis of variance. The duration of hemodialysis appeared to be the main predictive factor (P=0.0003) for DSA, which was found in six patients (19%). DSA was found to correlate with higher levels of beta2-microglobulin (P<0.00001), parathyroid hormone (P<0.05), and alkaline phosphatase (P<0.05). Clinical symptoms were minimal. In two patients, MR imaging revealed changes mimicking spondylodiscitis. In another patient, CT of the craniocervical junction showed bone resorption due to a pseudotumor, and basilar invagination. DSA of the cervical spine is often clinically silent. Pathogenesis of DSA may be multifactorial but its progression is most influenced by the duration of hemodialysis. On MR imaging, DSA may mimic spondylodiscitis. (orig.)

    Full Text Available Surgical site infection (SSI following spine surgery is a dreaded complication with significant morbidity and economic burden. SSIs following spine surgery can be superficial, characterized by obvious wound drainage, or deep-seated with a healed wound. Staphylococcus aureus remains the principal causal agent. There are certain pre-operative risk factors that increase the risk of SSI, mainly diabetes, smoking, steroids, and peri-operative transfusions. Additionally, intra-operative risk factors include surgical invasiveness, type of fusion, implant use, and traditional instead of minimally invasive approach. A high level of suspicion is crucial to attaining an early definitive diagnosis and initiating appropriate management. The most common presenting symptom is back pain, usually manifesting 2 to 4 weeks and up to 3 months after a spinal procedure. Scheduling a follow-up visit between weeks 2 to 4 after surgery is therefore necessary for early detection. Inflammatory markers are important diagnostic tools, and comparing pre-operative with post-operative levels should be done when suspecting SSIs following spine surgery. Particularly, Serum Amyloid A (SAA is a novel inflammatory marker that can expedite the diagnosis of SSIs. Magnetic resonance imaging remains the diagnostic modality of choice when suspecting a SSI following spine surgery. While 18F-fluorodeoxyglucose-positron emission tomography is not widely used, it may be useful in challenging cases. Despite their low yield, blood cultures should be collected before initiating antibiotic therapy. Samples from wound drainage should be sent for Gram stain and cultures. When there is a high clinical suspicion of SSI and in the absence of superficial wound drainage, CT guided aspiration of paraspinal collections is warranted. Unless the patient is hemodynamically compromised, antibiotics should be deferred until proper specimens for culture are secured.

    To investigate the outcomes and reliability of hybrid surgery (HS) versus anterior cervical discectomy and fusion (ACDF) for the treatment of multilevel cervical spondylosis and disc diseases.Hybrid surgery, combining cervical disc arthroplasty (CDA) with fusion, is a novel treatment to multilevel cervical degenerated disc disease in recent years. However, the effect and reliability of HS are still unclear compared with ACDF.To investigate the studies of HS versus ACDF in patients with multilevel cervical disease, electronic databases (Medline, Embase, Pubmed, Cochrane library, and Cochrane Central Register of Controlled Trials) were searched. Studies were included when they compared HS with ACDF and reported at least one of the following outcomes: functionality, neck pain, arm pain, cervical range of motion (ROM), quality of life, and incidence of complications. No language restrictions were used. Two authors independently assessed the methodological quality of included studies and extracted the relevant data.Seven clinical controlled trials were included in this study. Two trials were prospective and the other 5 were retrospective. The results of the meta-analysis indicated that HS achieved better recovery of NDI score (P = 0.038) and similar recovery of VAS score (P = 0.058) compared with ACDF at 2 years follow-up. Moreover, the total cervical ROM (C2-C7) after HS was preserved significantly more than the cervical ROM after ACDF (P = 0.000) at 2 years follow-up. Notably, the compensatory increase of the ROM of superior and inferior adjacent segments was significant in ACDF groups at 2-year follow-up (P multilevel cervical spondylosis to preserve cervical ROM and reduce the risk of adjacent disc degeneration. Nonetheless, more well-designed studies with large groups of patients are required to provide further evidence for the benefit and reliability of HS for the treatment of cervical disk diseases.

    In clinically severe cervical spondylosis, imaging plays a vital role in surgical decisions. A prime factor is acquired canal stenosis with cord compression. To validate this concept, the clinical and imaging features of 20 patients with spondylitic myelopathy and 24 with radiculopathy were retrospectively reviewed. All had computed tomographic myelography (CTM) as part of their clinical work-up. The patients` clinical severity was graded as mild, moderate and severe; the age, length of illness and a history of eventual surgery or otherwise were recorded. At the level of maximum compression the following parameters were obtained from the axial CTM images: surface area and ratio of the anteroposterior to the transverse diameter of the cord; subarachnoid space and vertebral canal areas. Data were statistically analysed. A significant association exists between surgery and increasing severity of symptoms (P=0.04), and advancing age (P=0.01). These associations hold true for myelopathy and radiculopathy. A strong association is present between surgery and the surface area of the cord (P=0.01), being applicable to myelopathy only. The other parameters show no association with surgical decisions. It is concluded that with myelopathy a narrow cord area at the level of maximum compression, and moderate-severe functional impairment are indicators for surgical intervention.

  8. Gd-DTPA-enhanced Three-dimensional MR imaging of degenerative disease of the cervical spine

    International Nuclear Information System (INIS)

    This paper assesses cervical spine three-dimensional (3D) MR imaging with Gd-DTPA, with the hypothesis that an enhanced 3D sequence with reconstructions would suffice for the evaluation of degenerative disease. Sixty patients were examined with (1) T1-weighted spin-echo and axial 2D gradient-echo low-flip-angle images representing the standard examination; and (2) one of two different enhanced 3D gradient-echo techniques: 30 patients with 3D fast low-angle shot (FLASH) imaging (TR 40/TE 7, 40 degrees flip angle, 64 2-mm sagittal partitions, one excitation, 10:67 minutes) and 30 with 3D Turbo FLASH imaging (MP RAGE) (7/5, 10 degrees, 128 1.5-mm partitions, one excitation, 6:07 minutes). 3D studies were reconstructed at 45 degrees obliquities for foramina, and axially. Standard and 3D studies were evaluated independently by two neuroradiologists for the location and size of extradural disease

    Clinical data is often captured in unstructured texts and scattered in different health information systems. This complicates the aggregation of information in the process of clinical decision making. However, having a quick overview and an efficient representation of relevant aspects of a patient's health status are crucial for this process. While accessing patient data and perusing clinical documents, relevant details need to be discovered quickly. In this paper, we introduce an approach to visualize relevant information from clinical documents by tag clouds. The conventional tag clouds visualize the content of a document using the terms they are containing shown in different sizes with the size calculated based on the term frequency. Important facts and diagnostic results with low occurrence in a text may be ignored by this naïve method. In this paper, we therefore adapt the conventional tag clouds by information extraction and a guidelines-based classification schema, so that the clinical concerns can be visualized more correctly. The aspects are extracted according to a classification schema developed by clinical experts. We evaluate the approach on a set of radiology reports for cervical spine treatment. PMID:27577333

    To compare CR with CT (static and dynamic) to evaluate upper spine instability and to determine if CT in flexion adds value compared to MR imaging in neutral position to assess compression of the subarachnoid space and of the spinal cord. Twenty-one consecutive patients with atlantoaxial subluxation due to rheumatoid arthritis planned for atlantoaxial fusion were included. CT and MRI were performed with the neck in the neutral position and CT also in flexion. CR in neutral position and flexion were obtained in all patients except for one subject who underwent examination in flexion and extension. CR and CT measurements of atlantoaxial subluxation correlated but were larger by CR than CT in flexion, however, the degree of vertical dislocation was similar with both techniques irrespective of the position of the neck. Cervical motion was larger at CR than at CT. The spinal cord compression was significantly worse at CT obtained in the flexed position as compared to MR imaging in the neutral position. Functional CR remains the primary imaging method but CT in the flexed position might be useful in the preoperative imaging work-up, as subarachnoid space involvement may be an indicator for the development of neurologic dysfunction.

    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.

    Minimally invasive spine surgery is increasingly used to treat various spinal pathologies with the goal of minimizing destruction of the surrounding tissues. Rhabdomyolysis (RM) is a rare but known complication of spine surgery, and acute renal failure (ARF) is in turn a potential complication of severe RM. The authors report the first known case series of RM and ARF following minimally invasive lateral spine surgery. The authors retrospectively reviewed data in all consecutive patients who underwent a minimally invasive lateral transpsoas approach for interbody fusion with the subsequent development of RM and ARF at 2 institutions between 2006 and 2009. Demographic variables, patient home medications, preoperative laboratory values, and anesthetic used during the procedure were reviewed. All patient data were recorded including the operative procedure, patient positioning, postoperative hospital course, operative time, blood loss, creatine phosphokinase (CPK), creatinine, duration of hospital stay, and complications. Five of 315 consecutive patients were identified with RM and ARF after undergoing minimally invasive lateral transpsoas spine surgery. There were 4 men and 1 woman with a mean age of 66 years (range 60-71 years). The mean body mass index was 31 kg/m2 and ranged from 25 to 40 kg/m2. Nineteen interbody levels had been fused, with a range of 3-6 levels per patient. The mean operative time was 420 minutes and ranged from 315 to 600 minutes. The CPK ranged from 5000 to 56,000 U/L, with a mean of 25,861 U/L. Two of the 5 patients required temporary hemodialysis, while 3 required only aggressive fluid resuscitation. The mean duration of the hospital stay was 12 days, with a range of 3-25 days. Rhabdomyolysis is a rare but known potential complication of spine surgery. The authors describe the first case series associated with the minimally invasive lateral approach. Surgeons must be aware of the possibility of postoperative RM and ARF, particularly in

    Full Text Available Abstract Background Although the effectiveness of manipulative therapy for treating back and neck pain has been demonstrated, the validity of many of the procedures used to detect joint dysfunction has not been confirmed. Practitioners of manual medicine frequently employ motion palpation as a diagnostic tool, despite conflicting evidence regarding its utility and reliability. The introduction of various spinal models with artificially introduced 'fixations' as an attempt to introduce a 'gold standard' has met with frustration and frequent mechanical failure. Because direct comparison against a 'gold standard' allows the validity, specificity and sensitivity of a test to be calculated, the identification of a realistic 'gold standard' against which motion palpation can be evaluated is essential. The objective of this study was to introduce a new, realistic, 'gold standard', the congenital block vertebra (CBV to assess the validity of motion palpation in detecting a true fixation. Methods Twenty fourth year chiropractic students examined the cervical spines of three subjects with single level congenital block vertebrae, using two commonly employed motion palpation tests. The examiners, who were blinded to the presence of congenital block vertebrae, were asked to identify the most hypomobile segment(s. The congenital block segments included two subjects with fusion at the C2–3 level and one with fusion at C5-6. Exclusion criteria included subjects who were frankly symptomatic, had moderate or severe degenerative changes in their cervical spines, or displayed signs of cervical instability. Spinal levels were marked on the subject's skin overlying the facet joints from C1 to C7 bilaterally and the motion segments were then marked alphabetically with 'A' corresponding to C1-2. Kappa coefficients (K were calculated to determine the validity of motion palpation to detect the congenitally fused segments as the 'most hypomobile' segments. Sensitivity

    Full Text Available INTRODUCTION : Expert airway management is the most essential requirement of an anesthesiologist . Difficult and failed intubation is the leading causes of anesthetic related morbidity and mortality. AIM OF STUDY: The purpose of this study was to compare the effectiveness of McCoy laryngoscope and McGrath video laryngoscope in tracheal intubation in patients using Manual in - line stabilization (MILS for cervical spine injury. MATERIALS AND METHODS : This study was condu cted in King George Hospital , Visakhapatnam, Andhra Pradesh on 60 patients aged 20 – 70, of American Society of Anesthesiologists physical status I – III, posted for elective surgery for cervical spine injury under general anesthesia. The patients were assigne d to two groups. One group was named as MC where McCoy laryngoscope was used, other group named as MG, where McGrath video laryngoscope was used for laryngoscopy during tracheal intubation . Two groups were compared on the basis of demogr aphic data, airway examination, comparison of visualization of vocal cords with McC oy laryngoscope and video laryngoscope and comparison of laryngoscope time. RESULTS: There was no significant difference between male and female sex. Most of the patients falls into Mallampati score I (60%, followed by score II and III (25 and 14% respectively. Statistically highly significant improvement in laryngoscope view was noted with video laryngoscope than with McCoy laryngoscope with Chi - square value=49.52; DF= 10; p - value=0.000(highl y significant. Statistically highly significant difference was seen in effective laryngoscopy time of McCoy and Video laryngoscope. CONCLUSION: We conclude McGrath video laryngoscope is superior to McCoy laryngoscope in terms of providing better intubatin g conditions in patients requiring MILS, though there is a little prolongation of effective laryngoscope time .

    Multidetector-row computed tomography (MRCT) has advantages in comparison to conventional helical computed tomography, such as reduction of study time, lower radiation doses, fewer metallic artifacts and high quality multiplanar reformatting and three dimensional reconstructions. We reviewed 150 cervical spine examinations and selected the most illustrative cases including congenital anomalies, degenerative lesions, spinal infections, neoplasms, traumatic injuries and postoperative abnormalities. The quality of multiplanar reformatting and volume reconstructions of the MRCT made the detection and evaluation of most of cases with complex anatomy easier and more precise. (author)

  5. Estimated Probability of a Cervical Spine Injury During an ISS Mission

    2013-01-01

    Introduction: The Integrated Medical Model (IMM) utilizes historical data, cohort data, and external simulations as input factors to provide estimates of crew health, resource utilization and mission outcomes. The Cervical Spine Injury Module (CSIM) is an external simulation designed to provide the IMM with parameter estimates for 1) a probability distribution function (PDF) of the incidence rate, 2) the mean incidence rate, and 3) the standard deviation associated with the mean resulting from injury/trauma of the neck. Methods: An injury mechanism based on an idealized low-velocity blunt impact to the superior posterior thorax of an ISS crewmember was used as the simulated mission environment. As a result of this impact, the cervical spine is inertially loaded from the mass of the head producing an extension-flexion motion deforming the soft tissues of the neck. A multibody biomechanical model was developed to estimate the kinematic and dynamic response of the head-neck system from a prescribed acceleration profile. Logistic regression was performed on a dataset containing AIS1 soft tissue neck injuries from rear-end automobile collisions with published Neck Injury Criterion values producing an injury transfer function (ITF). An injury event scenario (IES) was constructed such that crew 1 is moving through a primary or standard translation path transferring large volume equipment impacting stationary crew 2. The incidence rate for this IES was estimated from in-flight data and used to calculate the probability of occurrence. The uncertainty in the model input factors were estimated from representative datasets and expressed in terms of probability distributions. A Monte Carlo Method utilizing simple random sampling was employed to propagate both aleatory and epistemic uncertain factors. Scatterplots and partial correlation coefficients (PCC) were generated to determine input factor sensitivity. CSIM was developed in the SimMechanics/Simulink environment with a

    To investigate the outcomes and reliability of hybrid surgery (HS) versus anterior cervical discectomy and fusion (ACDF) for the treatment of multilevel cervical spondylosis and disc diseases.Hybrid surgery, combining cervical disc arthroplasty (CDA) with fusion, is a novel treatment to multilevel cervical degenerated disc disease in recent years. However, the effect and reliability of HS are still unclear compared with ACDF.To investigate the studies of HS versus ACDF in patients with multilevel cervical disease, electronic databases (Medline, Embase, Pubmed, Cochrane library, and Cochrane Central Register of Controlled Trials) were searched. Studies were included when they compared HS with ACDF and reported at least one of the following outcomes: functionality, neck pain, arm pain, cervical range of motion (ROM), quality of life, and incidence of complications. No language restrictions were used. Two authors independently assessed the methodological quality of included studies and extracted the relevant data.Seven clinical controlled trials were included in this study. Two trials were prospective and the other 5 were retrospective. The results of the meta-analysis indicated that HS achieved better recovery of NDI score (P = 0.038) and similar recovery of VAS score (P = 0.058) compared with ACDF at 2 years follow-up. Moreover, the total cervical ROM (C2-C7) after HS was preserved significantly more than the cervical ROM after ACDF (P = 0.000) at 2 years follow-up. Notably, the compensatory increase of the ROM of superior and inferior adjacent segments was significant in ACDF groups at 2-year follow-up (P benefit and reliability of HS for the treatment of cervical disk diseases.

    Kinematic MRI of the cervical spine was done from 50 of inclination to 30 of reclination. Depending on the maximum inclination and reclination the range of motion was divided into 9 equal angle positions. At each angle position sagittal T{sub 2}{sup `} weighted gradient echo sequences were performed. In relation to the neutral position a physiological narrowing of the ventral epidural space was seen in healthy volunteers at inclination (50 ) in up to 50% and respectively widening at reclination (30 ) in up to 10%. An increase of spinal canal stenosis or even spinal cord compression was seen at inclination in 5 patients (22%) and in 15 patients (65%) at reclination. No change of spinal canal stenosis was found in three patients (13%).

    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.

    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 evaluate the signal intensity (SI) of the intervertebral discs of the cervical spine on magnetic resonance (MR) fluid sensitive sequences, and correlate this to secondary signs of degeneration on MR and radiographs as well as to age. A total of 265 patients aged ≥16 with back pain (≥3-months, <2-year, onset <45-years) from the SPondyloArthritis Caught Early (SPACE) cohort were included. Sagittal 1.5 T MR images and lateral radiographs of the cervical spine were independently evaluated by two readers for: SI of the intervertebral discs using a grading system based of Pfirrmann (grade 1 normal/bright SI; 2 inhomogeneous/bright SI; 3 inhomogeneous/mildly decreased SI; 4 inhomogeneous/markedly decreased SI; 5 signal void), disc herniation and Modic changes (MRI) and disc space narrowing, osteophytes and sclerosis (radiograph). Readers were blinded for clinical information. Descriptive statistics were used for characteristics and prevalence of findings, and regression analysis was used for age and grades. Of 265 patients (36 % male, mean age 30), 221 (83 %) patients had 1 to 6 discs (median 4) with decreased SI. Of 1,590 discs, 737 (46 %) were grade 1; 711 (45 %) grade 2; 133 (8 %) grade 3; 8 (1 %) grade 4 and 1 (0 %) grade 5. Secondary signs of degeneration were rare and seen predominantly in C5-C7 and appear to be related to signal loss grade 3 and 4. Low signal intensity of intervertebral discs in absence of secondary degenerative signs in the cervical spine on fluid sensitive MR images might be pre-existing and part of the natural course.

    Significant progress has been made in image-guided surgery (IGS) over the last few decades. IGS can be effectively applied to spinal instrumentation surgery. In the present study, we focused our attention on the feasibility and safety of image-guided spine stabilization for traumatic or osteoporotic spine injury. The IGS spine fixation with or without minimally invasive surgery (MIS) techniques such as percutaneous screw placement, balloon kyphoplasty (BKP), or vertebroplasty (VP) were accomplished in 80 patients with traumatic or osteoprotic spine injury between 2007 and 2015. The injured vertebral levels included the following: cervical spine, 41; thoracic spine, 22; and lumbar spine, 17. Neurological condition before and after surgery was assessed using the American Spinal Injury Association Impairment Scale (AIS). A total of 419 pedicle, lateral mass, or laminar screws were placed, and 399 screws (95.2%) were found to be placed correctly based on postoperative computed tomography scan. Although 20 screws (4.8%) were found to be unexpectedly placed incorrectly, no neural or vascular complications closely associated with screw placement were encountered. Neurological outcomes appeared to be acceptable or successful based on AIS. The IGS is a promising technique that can improve the accuracy of screw placement and reduce potential injury to critical neurovascular structures. The integration of MIS and IGS has proved feasible and safe in the treatment of traumatic or osteoporotic spine injury, although a thorough knowledge of surgical anatomy, spine biomechanics, and basic technique remain the most essential aspects for a successful surgery.

    AIM: To ascertain the level at which intervertebral disc degeneration of the cervical spine most commonly occurs in each decade from 20-79 years. MATERIALS AND METHODS: Using computer analysis, we retrospectively assessed the mean signal intensity from each cervical disc from T2-weighted spin-echo images in 60 symptomatic patients (10 per decade from the third to eighth inclusive). RESULTS: Age, disc level and interaction between age and level were highly significant predictors for the magnetic resonance imaging (MRI) mean signal intensity from intervertebral discs (p<0.0001 for all three terms). The MRI signals were generally lower as age increased and also for the higher discs (C2-C3, etc). CONCLUSION: In our study we have shown that in younger patients the higher discs are more frequently affected by degeneration than the lower ones. As age increases, the process of degeneration becomes more generalized with less variability between discs.

    The current standard of care for patients with spinal disorders involves a thorough clinical history, physical exam, and imaging studies. Simple radiographs provide a valuable assessment but prove inadequate for surgery planning because of the complex 3-dimensional anatomy of the spinal column and the close proximity of the neural elements, large blood vessels, and viscera. Currently, clinicians still use primitive techniques such as paper cutouts, pencils, and markers in an attempt to analyze and plan surgical procedures. 3D imaging studies are routinely ordered prior to spine surgeries but are currently limited to generating simple, linear and angular measurements from 2D views orthogonal to the central axis of the patient. Complex spinal corrections require more accurate and precise calculation of 3D parameters such as oblique lengths, angles, levers, and pivot points within individual vertebra. We have developed a clinician friendly spine surgery planning tool which incorporates rapid oblique reformatting of each individual vertebra, followed by interactive templating for 3D placement of implants. The template placement is guided by the simultaneous representation of multiple 2D section views from reformatted orthogonal views and a 3D rendering of individual or multiple vertebrae enabling superimposition of virtual implants. These tools run efficiently on desktop PCs typically found in clinician offices or workrooms. A preliminary study conducted with Mayo Clinic spine surgeons using several actual cases suggests significantly improved accuracy of pre-operative measurements and implant localization, which is expected to increase spinal procedure efficiency and safety, and reduce time and cost of the operation.

    Background It has been found that significantly different clinical outcomes occur in trauma patients with different mechanisms of injury. Ground level falls (GLF) are usually considered “minor trauma” with less injury occurred in general. However, it is not uncommon that geriatric trauma patients sustain cervical spine (C-spine) fractures with other associated injuries due to GLF or less. The aim of this study is to determine the injury patterns and the roles of clinical risk factors in these...

    Objective To study the effect of the expansive open-door laminoplasty on the three-dimensional motion and stiffness of the cervical spine. Methods 55 cases after open-door laminoplasty of cervical spine due to myelopathy were follow-up for an average of 35.9 months. Cervical axial symptoms, neural functionality (JOA scoring system) and pre- and post-surgery dynamic cervical spine lateral X-ray films were evaluated. The Three-dimensional Motion and Stiffness of the Cervical Spine of Human Body Measuring Equipment was used in 12 post-operative open door laminoplasty cases and 10 pre-operative cases to measure the active and passive range of motion(ROM), load-displacement relationship, stiffness of cervical spine and torque caused by the isometric contraction of the extensors and flexors of the cervical spine. Results The average rate of improvement was 66. 2%. The excellent and good rate was 78.2%. The number of cases with distinct or severe cervical axial symptoms increased after the surgery ( P < 0. O1 ) . The patients who have severe axial symptoms tend to have less curved cervical spine (P < 0. 01 ) . There was no significant statistic difference between the severity of post-surgery cervical axial symptoms and JOA improvement level (P > 0. 05). The active and passive ROM of extension, rotation and lateral bending of cervical spine were decreased after the surgery ( P < 0. 05), and the main affection was on the middle and lower part of the cervical spine. The load-displacement figure of cervical spine can fit into an exponential equation T= b0eb1θ. In each direction, the lateral bending had the strongest stiffness, then the extension and flexion. The stiffness of rotation was the weakest. The stiffness of cervical spine of the post-surgery group was stronger than that of the contrast group. Conclusion The open-door laminoplasty of cervical spine damages the static mechanic balance on the sagittal plane and decreases the ROM and the flexibility of cervical

    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.

    Mucopolysaccharidosis I (MPS I) is a lysosomal storage disease characterized by deficient α-L-iduronidase activity, leading to the accumulation of poorly degraded glycosaminoglycans (GAGs). Children with MPS I exhibit high incidence of spine disease, including accelerated disc degeneration and vertebral dysplasia, which in turn lead to spinal cord compression and kypho-scoliosis. In this study we investigated the efficacy of neonatal enzyme replacement therapy (ERT), alone or in combination with oral simvastatin (ERT+SIM) for attenuating cervical spine disease progression in MPS I, using a canine model. Four groups were studied: normal controls; MPS I untreated; MPS I ERT treated; and MPS I ERT+SIM treated. Animals were euthanized at one year-of-age. Intervertebral disc condition and spinal cord compression were evaluated from MRIs and plain radiographs, vertebral bone condition and odontoid hypoplasia were evaluated using microcomputed tomography, and epiphyseal cartilage to bone conversion was evaluated histologically. Untreated MPS I animals exhibited more advanced disc degeneration and more severe spinal cord compression than normal animals. Both treatment groups resulted in partial preservation of disc condition and cord compression, with ERT+SIM not significantly better than ERT alone. Untreated MPS I animals had significantly lower vertebral trabecular bone volume and mineral density, while ERT treatment resulted in partial preservation of these properties. ERT+SIM treatment demonstrated similar, but not greater, efficacy. Both treatment groups partially normalized endochondral ossification in the vertebral epiphyses (as indicated by absence of persistent growth plate cartilage), and odontoid process size and morphology. These results indicate that ERT begun from a very early age attenuates the severity of cervical spine disease in MPS I, particularly for the vertebral bone and odontoid process, and that additional treatment with simvastatin does not

    Full Text Available The WEI Jet Endotracheal Tube (WEI JET is a new tracheal tube that facilitates both oxygenation and ventilation during the process of intubation and assists tracheal intubation in patients with difficult airway. We evaluated the effectiveness and usefulness of the WEI JET in combination with lightwand under direct laryngoscopy in difficult tracheal intubation due to unstable cervical spine.Ninety patients with unstable cervical spine disorders (ASA I-III with general anaesthesia were included and randomly assigned to three groups, based on the device used for intubation: lightwand only, lightwand under direct laryngoscopy, lightwand with WEI JET under direct laryngoscopy.No statistically significant differences were detected among three groups with respect to demographic characteristics and C/L grade. There were statistically significant differences between three groups for overall intubation success rate (p = 0.015 and first attempt success rate (p = 0.000. The intubation time was significantly longer in the WEI group (110.8±18.3 s than in the LW group (63.3±27.5 s, p = 0.000 and DL group (66.7±29.4 s, p = 0.000, but the lowest SpO2 in WEI group was significantly higher than other two groups (p<0.01. The WEI JET significantly reduced successful tracheal intubation attempts compared to the LW group (p = 0.043. The severity of sore throat was similar in three groups (p = 0.185.The combined use of WEI JET under direct laryngoscopy helps to assist tracheal intubation and improves oxygenation during intubation in patients with difficult airway secondary to unstable spine disorders.Chinese Clinical Trial Registry ChiCTR-TRC-14005141.

    2011-07-01

    Full Text Available Abstract Background Vertebral artery injury (VAI after blunt cervical trauma occurs more frequently than historically believed. The symptoms due to vertebral artery (VA occlusion usually manifest within the first 24 hours after trauma. Misdiagnosed VAI or delay in diagnosis has been reported to cause acute deterioration of previously conscious and neurologically intact patients. Case presentation A 67 year-old male was involved in a motor vehicle crash (MVC sustaining multiple injuries. Initial evaluation by the emergency medical response team revealed that he was alert, oriented, and neurologically intact. He was transferred to the local hospital where cervical spine computed tomography (CT revealed several abnormalities. Distraction and subluxation was present at C5-C6 and a comminuted fracture of the left lateral mass of C6 with violation of the transverse foramen was noted. Unavailability of a spine specialist prompted the patient's transfer to an area medical center equipped with spine care capabilities. After arrival, the patient became unresponsive and neurological deficits were noted. His continued deterioration prompted yet another transfer to our Level 1 regional trauma center. A repeat cervical spine CT at our institution revealed significantly worsened subluxation at C5-C6. CT angiogram also revealed complete occlusion of bilateral VA. The following day, a repeat CT of the head revealed brain stem infarction due to bilateral VA occlusion. Shortly following, the patient was diagnosed with brain death and care was withdrawn. Conclusion Brain stem infarction secondary to bilateral VA occlusion following cervical spine trauma resulted in fatal outcome. Prompt imaging evaluation is necessary to assess for VAI in cervical trauma cases with facet joint subluxation/dislocation or transverse foramen fracture so that treatment is not delayed. Additionally, multiple transportation events are risk factors for worsening when unstable cervical

    The purpose of the study was to evaluate the accuracy and precision of a rigid positioning device for repositioning the cervical spine accurately and precisely during conformal radiation therapy of dogs. Fifteen purpose bred research dogs in a radiation therapy study were included. The dogs were positioned using a head holder and a deflatable pillow attached to the treatment table. Port films were reviewed retrospectively, and repositioning precision was recorded by measurements in three orthogonal planes of the head, 2nd cervical vertebra and 1st thoracic spinous process. Mean treatment position was compared to the planning position for a measurement of systematic set-up error. Mean interfraction position variation of the 2nd cervical vertebra was 0.2, 0.1 and 0.2 cm for the ventrodorsal, caudocranial and laterolateral directions respectively, and the average systematic set up error was 0.2, 0.1 and 0.2 cm for the ventrodorsal, caudocranial and laterolateral directions respectively. Knowledge of the magnitude of reposition errors should be included when determining the margins around the tumor. PMID:14703256

    Objective To evaluate the impact of polyhydramnios on preoperative cervical length and whether cervical length recovery after amnioreduction during selective fetoscopic laser photocoagulation (SFLP) is associated with a greater gestational age at delivery in pregnancies complicated by twin-twin transfusion syndrome (TTTS). Methods Retrospective study of 50 pregnancies complicated by TTTS treated with SFLP between March 2010 and July 2014 at a single center. Preoperative maximum vertical pocket (MVP) was measured along with pre- and postoperative cervical length. A cervical length difference was calculated, with a difference of ± 3 mm considered no change. Results Only 12 (34%) patients showed an increased cervical length after amnioreduction during laser surgery. There was no statistical difference between either negative or positive change in cervical length groups and mean gestational age at delivery (p = 0.82). There also was no correlation between preoperative MVP and preoperative cervical length (p = 0.36) or gestational age at delivery (p = 0.77). However, there was a statistically shorter mean preoperative cervical length in patients who delivered polyhydramnios does not correlate with preoperative cervical length, and variability of the cervix postoperatively does not appear to affect gestational age at delivery.

    2011-05-15

    Background: Cervical spine radiography is a commonly employed examination for degenerative disease and trauma in the cervical spine. Traditionally, the anteroposterior projection is undertaken with the use of an anti-scatter grid. Some practitioners appear to have rejected this practice in favour of a non-grid technique, possibly because of the dose saving it affords. It is necessary to determine if image quality in the cervical spine is significantly degraded and whether the omission of the grid is justified. Method: Using a slaughtered lamb neck as a model of the human neck triplicate radiographs were obtained using a non-grid, a stationary grid and a moving grid technique. Entrance surface dose and dose area product was measured for these techniques. Image quality in terms of contrast, sharpness and overall acceptability was evaluated by 9 independent and blinded observers. Results: A significant reduction in measured dose was observed when the non-grid technique was compared to stationary or moving grid techniques. A statistically significant reduction in image contrast, sharpness and acceptability was also seen in the non-grid compared to grid techniques. Conclusion: These results show evidence of significantly greater image quality in the presence of either a moving or stationary grid in the lamb model. As such they support the continued use of scatter rejection methods such as the anti-scatter grid in AP radiography of the human cervical spine, to optimise radiographic image quality in this critical structure.

    This report presents two cases of cervicobrachialgia and radiculopathy due to multiple cervical herniated discs and spur formation that dealt with anterior cervical discectomy and fusion (ACDF) using different titanium interbody cages. The description of the clinical presentation, magnetic resonance imaging (MRI) appearances and management strategy are discussed. Both cases showed chronic neck pain and radiating pain from the shoulder to the arm. They had a history of blurry vision, cluster head ache, weakness, and numbness on the shoulder for 2 years. MRI revealed multiple herniated discs between C4-7 and accompanied by the spur formation leading to the narrowness of the spinal canal and its foramina bilaterally. ACDF were performed and complete decompression of the spinal canal and its foramina were carried out. Twin M-cages (Ammtec Inc.-Japan) were placed in the first case at C5-7 levels and single cage of Smith Robinson (SR) was placed in the second case at C5-6 levels. There were no more blurry vision, cluster headache, weakness, and numbness, immediately after surgery. To our knowledge, this is the first reported cases of ACDF, using twin M-cages and single SR cage in Indonesia, with improvement immediately after surgery. Cervical spondylosis can present with cervicobrachialgia and radiculopathy and surgical treatment produces good functional outcome. PMID:27695567

    Conclusion: Cervical cancer survivors treated with radiotherapy had worse sexual functioning than did those treated with radical hysterectomy and lymph node dissection. Appropriate measures like Pelvic exercises, Yoga, vaginal dilators, vaginal cream should be used to decrease radiotherapy related side effects on sexual functioning. Cervical cancer survivors treated with surgery alone can expect overall quality of life and sexual function not unlike that of peers without a history of cancer.

    This study was aimed to explore the anterior cervical surgery methods to treat central cord syndrome without radiographic spinal fracture-dislocation (CCSWORFD), retrospectively analyze the cases of CCSWORFD, and evaluate the curative effect of anterior cervical surgery methods for CCSWORFD. Twenty four cases of CCSWORFD (19 males and 5 females), all suffering from cervical hyperextension injury, between 45-68 (average 59) years old, were operated on by anterior cervical surgery methods. Among these, 18 cases had been followed up for 6-24 (average 15) months; 18 cases, who had anterior decompression and plate fixation with titanium mesh bone grafting or iliac bone grafting achieved reliable effects based on the Japanese Orthopedics Association (JOA) evaluation (improved scores of cases with titanium mesh bone grafting, t = 2.800, P0.05). Most of these cases had degeneration of cervical vertebra. The decompression which relieves the oppression to the spinal cord can help lessen edema of the spinal cord, and early fixation for stability of cervical vertebra is better for the recovery of spinal cord injury. Anterior operation with titanium mesh bone grafting or iliac bone grafting are both reliable curative methods for CCSWORFD, and titanium mesh bone grafting can avoid the trauma of the supplying graft. Mesh bone grafting can also shorten hospital stay.

    Full Text Available The authors report a case of metastatic gastrointestinal adenocarcinoma to the cervical spine in a patient with acquired immunodeficiency syndrome (AIDS being treated with antiretroviral therapy. The source of this tumor could not be identified despite a thorough evaluation. A 49-year-old male being treated for AIDS presents with worsening neck pain and left distal arm weakness. MRI demonstrated an erosive mass within the cervical four vertebral body extending through the pedicle on the left side. Patient underwent needle biopsy followed by combined anterior and posterior fusion procedures. Pathology demonstrated metastatic gastrointestinal adenocarcinoma without known primary origin. He is currently undergoing palliative radiotherapy. This is an unusual case of metastatic gastrointestinal adenocarcinoma to the cervical spine. This should be included on the differential diagnosis of spinal lesions in this patient population and may represent a unique tumor in patients with HIV/AIDS who are on immunosuppressive therapy.

    Full Text Available Context: The cervical spine has to be stabilized in patients with suspected cervical spine injury during laryngoscopy and intubation by manual in-line axial stabilization. This has the propensity to increase the difficulty of intubation. An attempt has been made to compare TruView EVO2 and McCoy with cervical spine immobilization, which will aid the clinician in choosing an appropriate device for securing the airway with an endotracheal tube (ETT in the clinical scenario of trauma. Aims: To compare the effectiveness of TruView EVO2 and McCoy laryngoscopes when performing tracheal intubation in patients with neck immobilization using manual in-line axial cervical spine stabilization. Settings and design: K. M. C. Hospital, Mangalore, This was a randomized control clinical trial. Methods: Sixty adult patients of either sex of ASA physical status 1 and 2 who were scheduled to undergo general anesthesia with endotracheal intubation were studied. Comparison of intubation difficulty score (IDS, hemodynamic response, Cormack and Lehane grade, duration of the tracheal intubation and rate of successful placement of the ETT in the trachea between TruView EVO2 and McCoy laryngoscopes was performed. Results: The results demonstrated that TruView has a statistically significant less IDS of 0.33 compared with an IDS of 1.2 for McCoy. TruView also had a better Cormack and Lehane glottic view (CL 1 of 77% versus 40% and less hemodynamic response. Conclusions: The TruView blade is a useful option for tracheal intubation in patients with suspected cervical spine injury.

    Anterior cervical discectomy and arthrodesis has come to represent standard of care for patients with persistent radicular and/or myelopathic symptoms that have failed to improve with conservative treatments. One potential complication of the procedure is the accelerated degeneration of the vertebrae and the intervertebral discs adjacent to the level fused and the effects of fusion on those levels. The concern that fusion may be a contributing factor to accelerated adjacent segment degenerati...

  6. Lymphoscintigraphy and radioguided surgery in cervical and vulvar malignant tumours

    International Nuclear Information System (INIS)

    Objective: To validate a combined technique in the detection of sentinel nodes in early cervix and vulvar cancer patients. Material and Methods: Seventy patients, 24 to 63 years old (average 40 years), with cervical cancer stages IA2, IB1 and IIA, and fourteen patients, 28 to 80 years old (median 68 years) with vulval neoplasm, stage I and II, had sentinel node (SN) detection using lymphoscintigraphy and a gamma probe in the surgical room, after injection of Tc 99m dextran and patent blue dye. Sentinel nodes were seen between 20 and 135 minutes after injection, in cervical cancer, and between one and sixty minutes in vulvar neoplasms. In patients with cervical tumors, 99 sentinel nodes were localized in the obturator region, 28 were interiliac, nine were located in the external iliac region, three in the common iliac region and one was found in perineum. In patients with a vulvar neoplasm, all sentinel nodes were located in the superficial inguinal region. The detection rate was 98,8% for cervical cancer and 100% for vulvar neoplasms, with bilateral drainage in 46% and 29% respectively. Metastases were found in 10,4% (7/65) of IB1 stage cervical cancer patients (6 squamous cell carcinomas - non keratinizing: 5, keratinizing: 1 and one adenocarcionoma) and none in four patients with IA2 stage (with non keratinizing squamous cell carcinoma). The patients with IIA stage cervical cancer (keratinizing squamous cell carcinoma) had metastases in the SN. Three out of 14 patients with vulvar cancer showed metastases in the sentinel node. Two of them had epidermoid carcinoma and one, malignant melanoma. There were no metastases in non-sentinel nodes when sentinel nodes were negative for metastases, both in cervical or vulvar cancer. Conclusion: It is feasible to localize sentinel nodes in cervical and vulvar cancer, using a combined technique with Tc 99m Dextran and 'patent blue'. (author)

    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

    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. PMID:26806151

    A better understanding of the consequences of spine surgery complications is warranted to optimize patient-reported outcomes and contain the rising health care costs associated with the management of adult spinal deformity (ASD). We systematically searched PubMed and Scopus databases using keywords "adult spinal deformity surgery," "complications," and "cost" for published studies on costs of complications associated with spinal surgery, with a particular emphasis on ASD and scoliosis. In the 17 articles reviewed, we identified 355,354 patients with 11,148 reported complications. Infection was the most commonly reported complication, with an average treatment cost ranging from $15,817 to $38,701. Hospital costs for patients with deep venous thrombosis, pulmonary thromboembolism, and surgical site infection were 2.3 to 3.1 times greater than for patients without those complications. An effort to collect and characterize data on cost of complications is encouraged, which may help health care providers to identify potential resources to limit complications and overall costs.

    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.

    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.

    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.

    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

    OBJECTIVE Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in adults. In spite of this, the impact of the changes in myelopathic signs following cervical decompression surgery and their relationship to functional outcome measures remains unclear. The main goals of our study were to prospectively assess changes in myelopathic signs with a functional outcome scale (the modified Japanese Orthopaedic Association [mJOA] scale) following cervical decompression surgery and to objectively test a proposed new myelopathy scale (MS). METHODS Between 2008 and 2011, 36 patients with CSM were observed following cervical decompression surgery. Patient data including mJOA and MS scores were prospectively collected and analyzed preoperatively and at 1 year after surgery. RESULTS In this cohort, reflex, Babinski, and proprioception signs showed statistically significant improvement following surgery at 1 year (p = < 0.001, p = 0.008, and p = 0.015, respectively). A lesser degree of improvement was observed with the Hoffman sign (p = 0.091). No statistically significant improvement in clonus occurred (p = 0.368). There was a significant improvement in mJOA (p ≤ 0.001) and MS (p ≤ 0.001) scores at 1 year compared with the preoperative scores. The results showed an inverse correlation between MS and mJOA scores both pre- and postoperatively (Spearman's correlation coefficient = -0.202 preoperatively and -0.361 postoperatively). CONCLUSIONS Improvement in myelopathic signs was noted following cervical decompression surgery in patients with CSM. The newly devised MS scale demonstrated these findings, and the new MS scale correlates with improvement in mJOA scores in this patient cohort. PMID:26849710

    Full Text Available We report the anaesthetic management of two cases involving surgeries on the clavicle, performed under superficial cervical plexus block and selective C5 nerve root block under ultrasound (US guidance, along with general anaesthesia. Regional analgesia for clavicular surgeries is challenging. Our patients also had significant comorbidities necessitating individualised approach. The first patient had a history of emphysema, obesity, and was allergic to morphine and hydromorphone. The second patient had clavicular arthritis and pain due to previous surgeries. He had a history of smoking, Stevens-Johnson syndrome, along with daily marijuana and prescription opioid use. Both patients had an effective regional block and required minimal supplementation of analgesia, both being discharged on the same day. Interscalene block with its associated risks and complications may not be suitable for every patient. This report highlights the importance of selective regional blockade and also the use of US guidance for an effective and safe block.

    2016-03-01

    Although a rare cancer in the developed world due to the success of cervical screening programmes, cervical cancer remains one of the most common cancers diagnosed in women under the age of 35 years old. Radical hysterectomy and more recently radical trachelectomy have been highly effective in curing the majority of women with early stage disease. Many, however, are left with long-term 'survivorship' issues including bowel, bladder and sexual dysfunction. In view of these chronic co-morbidities, many clinicians now consider whether a less radical approach to surgery may be an option for some women. This review focuses on the current evidence for the safety of conservative surgery for early stage cervical cancer with regard to cure rates in comparison to standard management, as well as any improvement in short and long-term morbidity associated with a more conservative approach.

    Full Text Available High cervical ossified ligamentum flavum (OLF is rare and may cause progressive quadriparesis and respiratory failure . Our two patients had unilateral OLF between C1 and C4 levels. MR showed a unilateral, triangular bony excrescence with low signal and a central, intermediate or high signal on all pulse sequences due to bone marrow within. There was Type I thecal compression (partial deficit of contrast media ring. The first patient had a linear and nodular OLF with calcification within tectorial membrane, C2-3 fusion and unilateral C2-facetal hypertrophy; and the second patient, a lateral, linear OLF with loss of lordosis and C3-6 spondylotic changes. A decompressive laminectomy using "posterior floating and enbloc resection" brought significant relief in myelopathy. Histopathology showed mature bony trabeculae, bone marrow and ligament tissue. The coexisting mobile cervical vertebral segment above and congenitally fused or spondylotic rigid segment below the level of LF may have led to abnormal strain patterns within resulting in its unilateral ossification. In dealing with cervical OLF, carefully preserving facets during laminectomy or laminoplasty helps in maintaining normal cervical spinal curvature.

    2010-10-01

    Full Text Available Abstract Background The risk associated with cervical manipulation is controversial. Research in this area is widely variable but as yet the risk is not easily quantifiable. This presents a problem when informing the patient of risks when seeking consent and information may be withheld due to the fear of patient withdrawal from care. As yet, there is a lack of research into the frequency of risk disclosure and consequent withdrawal from manipulative treatment as a result. This study seeks to investigate the reality of this and to obtain insight into the attitudes of chiropractors towards informed consent and disclosure. Methods Questionnaires were posted to 200 UK chiropractors randomly selected from the register of the General Chiropractic Council. Results A response rate of 46% (n = 92 was achieved. Thirty-three per cent (n = 30 respondents were female and the mean number of years in practice was 10. Eighty-eight per cent considered explanation of the risks associated with any recommended treatment important when obtaining informed consent. However, only 45% indicated they always discuss this with patients in need of cervical manipulation. When asked whether they believed discussing the possibility of a serious adverse reaction to cervical manipulation could increase patient anxiety to the extent there was a strong possibility the patient would refuse treatment, 46% said they believed this could happen. Nonetheless, 80% said they believed they had a moral/ethical obligation to disclose risk associated with cervical manipulation despite these concerns. The estimated number of withdrawals throughout respondents' time in practice was estimated at 1 patient withdrawal for every 2 years in practice. Conclusion The withdrawal rate from cervical manipulation as a direct consequence of the disclosure of associated serious risks appears unfounded. However, notwithstanding legal obligations, reluctance to disclose risk due to fear of increasing patient

    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.

    Full Text Available Objective To investigate the clinical characteristics and surgical treatment strategy of intra- and extra-spinal dumbbell-shaped tumors in cervical spine. Methods Clinical data of 11 patients with intra- and extra-spinal dumbbell-shaped tumors in cervical spine were retrospectively studied. Male was in 7 cases, female in 4 cases. The tumors were in stageⅠin 4 cases, Ⅱ in 2 cases, Ⅲ in 4 cases and Ⅳ in one case. The tumors were resected via posterior midline approach alone in 9 cases, among whom unilateral hemilaminectomy was performed in 4 cases (screw fixation via posterior approach was performed for fusion of lesion segments after tumor resection in 2 cases, one was stage Ⅳ tumor, another one was stage Ⅲ tumor in cervicothoracic junction, total laminotomy and reduction by titanium miniplates and screws in 2 cases, and via interlaminar approach in 3 cases. Posterior midline approach combined with anterior lateral approach was performed in the rest 2 cases. Results Tumors were one-stage totally resected in all of the cases. Histological types of the tumors included schwannoma in 10 cases, and ganglioneuroma in one case. The numbness area was enlarged in one case, and the motor function improved in other cases. All of the patients were followed-up from 8 months to 3.50 years with an average of 21 months. No tumor relapse and spinal deformity were found. Conclusion Most cases of intra- and extra-spinal dumbbell-shaped tumors can be treated with one-stage microsurgery. The surgical treatment strategy can be reached according to the location and surgical staging of tumors. Unilateral hemilaminectomy technique is useful to maintain the stability of the cervical spine for most of tumors. Combined approach is needed in some of the tumors and fixation should be implemented in the case of stability of cervical spine damaged after tumor resection.

    Background: Prospective analysis of local tumor control, survival and treatment complications in 67 consecutive patients treated with fractionated photon and proton radiation for chordoma or chondrosarcoma of the base of the skull and the cervical spine. Patients and Methods: Between December 1995 and January 2000, 67 patients with a median age of 52 years (range: 14-85 years), were treated at the Centre de Protontherapie d'Orsay (CPO), France, using the 201-MeV proton beam, 49 for chordoma and 18 for chondrosarcoma. Irradiation combined high-energy photons and protons. Photons represented two thirds of the total dose and protons one third. The median total dose delivered within gross tumor volume (GTV) was 67 cobalt gray equivalents (CGE; range: 60-70 CGE). Results: Within a median follow-up of 29 months (range: 4-71 months), the 3-year local control rates were 71% and 85% for chordomas and chondrosarcomas, respectively, and the 3-year overall survival rates 88% and 75%, respectively. 14 tumors (21.5%) failed locally (eight within the GTV, four within the clinical target volume [CTV], and two without further assessment). Seven patients died from their tumor and another one from a nonrelated condition (pulmonary embolism). The maximum tumor diameter and, similarly, the GTV were larger in relapsing patients, compared with the rest of the population: 56 mm vs 44 mm (p = 0.024) and 50 ml vs 22 ml (p = 0.0083), respectively. In univariate analysis, age {<=} 52 years at the time of radiotherapy (p = 0.002), maximum diameter < 45 mm (p = 0.02), and GTV < 28 ml (p = 0.02) impacted positively on local control. On multivariate analysis, only age was an independent prognostic factor of local control. Conclusion: In chordomas and chondrosarcomas of the skull base and cervical spine, combined photon and proton radiation therapy offers excellent chances of cure. In two thirds of the cases, relapses are located in the GTV. Maximum diameter, GTV, and age are prognostic

    Saethre-Chotzen syndrome (SCS) and Muenke-type mutation (MTM) are complex syndromes with craniosynostosis and skeletal anomalies including syndactyly, carpal and tarsal fusions, and cervical spine abnormalities. In this study, we analysed radiographs of the cervical spine, hands and feet of a large patient population with genetically proven SCS and MTM. The aim was to describe the pattern of skeletal anomalies and to determine whether specific features are present that could help differentiate between the two entities. Radiographs of 43 patients (23 males, 20 females) with SCS (n=35) or MTM (n=8) were evaluated. The median age was 8 years (range 1 month-36 years). All radiographs were reviewed by two radiologists. In the hands and feet, a variety of anomalies such as brachyphalangy, clinodactyly, partial syndactyly, partial carpal or tarsal fusion, and cone-shaped epiphyses were noted. Duplicated distal phalanx of the hallux (n=12/35) and triangular deformity of the epiphysis of the distal phalanx of the hallux (n=10/35) were detected in SCS only; calcaneo-cuboid fusion (n=2/35) was detected in MTM only. In the cervical spine, fusion of vertebral bodies and/or the posterior elements occurred only in patients with SCS. Pathognomonic signs for SCS are the triangular shape of the epiphysis and duplicated distal phalanx of the hallux. Calcaneo-cuboid fusion was detected in MTM only. These signs may be helpful in the differentiation of SCS from MTM. (orig.)

    2015-03-01

    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.

    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.

    OBJECTIVE The aim of this study was to describe patient radiation exposure during single-level transforaminal endoscopic lumbar discectomy procedures at levels L2-5 and L5-S1. METHODS Radiation exposure was monitored in 151 consecutive patients undergoing single-level transforaminal endoscopic lumbar discectomy procedures. Two groups were studied: patients undergoing procedures at the L4-5 level or above and those undergoing an L5-S1 procedure. RESULTS For the discectomy procedures at L4-5 and above, the average duration of fluoroscopy was 38.4 seconds and the mean calculated patient radiation exposure dose was 1.5 mSv. For the L5-S1 procedures, average fluoroscopy time was 54.6 seconds and the mean calculated radiation exposure dose was 2.1 mSv. The average patient radiation exposure dose among these cases represents a 3.5-fold decrease compared with the senior surgeon's first 100 cases. CONCLUSIONS Transforaminal lumbar endoscopic discectomy can be used as a minimally invasive technique for the treatment of lumbar radiculopathy in the setting of a herniated lumbar disc without the significant concern of exposing the patient to harmful doses of radiation. One caveat is that both the surgeon and the patient are likely to be exposed to higher doses of radiation during a surgeon's early experience in minimally invasive endoscopic spine surgery.

    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.

    Full Text Available We performed fixation using laminar screws in 2 patients in whom lateral mass screws, pedicle screws or transarticular screws could not be inserted. One was a 56-year-old woman who had anterior atlantoaxial subluxation (AAS. When a guide wire was inserted using an imaging guide, the hole bled massively. We thought the re-insertion of a guide wire or screw would thus increase the risk of vascular injury, so we used laminar screws. The other case was an 18-year-old man who had a hangman fracture. Preoperative magnetic resonance angiography showed occlusion of the left vertebral artery. A laminar screw was inserted into the patent side (i.e., the right side of C2. Cervical pedicle screws are the most biomechanically stable screws. However, their use carries a high risk of neurovascular complications during screw insertion, because the cervical pedicle is small and is adjacent laterally to the vertebral artery, medially to the spinal cord, and vertically to the nerve roots. Lateral mass screws are also reported to involve a risk of neurovascular injuries. The laminar screw method was thus thought to be useful, since arterial injuries could thus be avoided and it could also be used as a salvage modality for the previous misinsertion.

    The BLADE (PROPELLER) technique reduces artefacts in imaging of the cervical spine in sagittal orientation, but till now failed to do so in axial orientation, because here it increased through plane CSF-flow artefacts, which spoiled the benefit of BLADE artefact reduction 'in plane'. The aim of this study was to compare a BLADE sequence with optimised measurement parameters in axial orientation to T2-TSE. Both sequences were compared in 58 patients with 31 discal, 16 bony and 11 spinal cord lesions. Image sharpness, reliability of spinal cord depiction, CSF flow artefacts and lesion detection were evaluated by 3 independent observers. Additionally the observers were asked which sequence they would prefer for diagnostic workup. Statistical evaluations were performed using sign and {sub X}2 test. BLADE was significantly superior concerning image sharpness, spinal cord depiction and overall lesion detection. BLADE was rated better for most pathologies, for bony lesions the differences compared with TSE were statistically significant. Regarding CSF-flow artefacts both sequences showed no difference. All readers preferred BLADE in side by side reading. An optimised axial T2 BLADE sequence decreases the problems of increased through plane CSF-flow artefacts in this orientation. By reducing various other artefacts it yields better image quality and has the potential to reduce the number of non-diagnostic examinations especially in uncooperative patients.

    2014-01-01

    Cervical spondylotic myelopathy(CSM) is the most common cause of spinal cord dysfunction and is caused by static or dynamic repeated compression of the spinal cord resulting from degenerative arthritis of the cervical spine and some biological injuries to the cervical spine. The T2 signal change on conventional magnetic resonance imaging(MRI) is most commonly associated with neurological deficits. Diffusion tensor imaging and MR spectroscopy show altered microstructure and biochemistry that reflect patient-specific pathogenesis and can be used to predict neurological outcome and response to intervention. Functional MRI can help to assess the neurological functional recovery after decompression surgery for CSM.

    We report on a rare case of connecting rod migration into the posterior cranial fossa after posterior cervical decompression and lateral mass screw fixation. A 55-year-old male patient who was operated on for ossification of posterior longitudinal ligament complained of sudden-onset giddiness followed by loss of consciousness one and half year following surgery. CT scan showed migration of left-sided connecting rod into the right cerebellum through foramen magnum. The patient was operated on for rod removal but he sustained a cardiorespiratory arrest and died on the eighth postoperative day. Autopsy confirmed damage to the right cerebellum due to rod migration. The clinician should be aware that superior rod migration is a rare but potentially disastrous complication. Regular follow-up with radiological evaluation should be done to look for implant loosening, migration, and non-union even in asymptomatic patients. The implant should be subsequently removed after it has served its purpose. PMID:26748502

    2016-06-01

    Percutaneous endoscopic cervical discectomy has evolved as an efficient, minimally invasive spine surgery for cervical disc herniation or radiculopathy. The development of the working channel endoscope makes definitive decompression surgery through a percutaneous approach feasible. There are two methods of approach to target the pathology: anterior and posterior approach. The approach can be determined according to the zone of pathology or the surgeon's preference. The most significant benefits of this endoscopic surgical technique are minimal access tissue trauma and early recovery from the intervention. However, this technique is still evolving and have a steep learning curve. Extensive development of surgical technique and working channel endoscopes will enable us to treat cervical disc herniation more practically. The objective of this review is to describe the cutting-edge techniques of endoscopic surgery in the cervical spine and to discuss the pros and cons of these minimally invasive surgical techniques.

    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.

    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.

    In the vertebral pedicle screw fixation surgery, to overcome the low positioning accuracy of manual operation and the fatigue during long time surgery, a spine surgery robot system used to assist the surgeons in the vertebral pedicle screw fixation surgery is performed. The robot has a configuration of five Degrees of freedom(Dofs). It is designed with full account of surgical safety and the effective coverage of operation space. Also, its kinematics is completely analyzed. The control system of the robot includes the active control mode based on the image navigation, and passive control mode based on a 6 Dofs force/torque sensor. In the active control mode, the doctor plans optimized location information for the screw path through the navigation system, and then the robot automatically locates the surgical point according to the planned path;passive control mode is based on admittance control principle, which maps the drag force acting on the end-effector to the motion of the robot. So that the robot moves following the drag action. The force drag control experiments verify the effectiveness of the passive control mode.%针对脊柱手术中的椎弓根钉内固定术,为克服医生操作手术时定位精度难以保证、长时间手术易疲劳等问题,设计了一套脊柱手术机器人系统用于辅助实施椎弓根钉内固定术。机器人为5自由度,充分考虑手术机器人对安全性和工作空间有效覆盖的要求,进行了构型设计,并完成了相应的机器人运动学分析。控制系统是由图像导航下的主动控制和基于力传感器的被动拖拽控制两个模式进行控制。主动控制下,医生通过导航系统提供最优钉道的精确位置信息,机器人根据医生的规划路径自主到达手术点;被动力拖拽控制基于导纳控制原理对医生作用在机器人末端执行器的操作力进行映射,并以此形成跟随拖动动作的机器人运动控制指令。针对力拖

    Nowdays, anterior cervical discectomy and fusion (ACDF) and cervical artificial disc replacement (CADR) are the most accepted procedure to treat multilevel cervical degenerative disc diseases. However, ACDF reduces the motion of the cervical spine and accelerates adjacent level degeneration. Strict indications and hyper-mobility of the operative levels may limit the application of multilevel CADR. Some experts put forward the method of Hybrid surgery incorporating ACDF and CADR. The purpose of this study is to review the progress of Hybrid surgery treating multilevel cervical degenerative disc diseases.%目前对于多节段颈椎退变性疾病的治疗术式中以颈前路减压植骨融合内固定术(anterior cervical discectomy and fusion,ACDF)和颈椎间盘置换术(cervical artificial disc replacement,CADR)为主,然而ACDF消除了颈椎融合节段的活动度,加速了颈椎临近节段的退变;CADR的适应证狭窄并且手术节段的活动度不理想。所以有学者提出在治疗多节段颈椎退行性疾病中将ACDF和CADR结合起来即Hybrid术式,笔者就目前Hybrid术式治疗多节段颈椎退行性疾病的研究进展做一综述。

    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.

    The aim of this study was to evaluate the efficacy and safety of neo-adjuvant chemotherapy (NACT) versus radical surgery (RS) for patients with cervical cancer. A meta-analysis of randomized controlled trials (RCT) of NACT + RS versus RS alone for patients with cervical cancer was performed according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. The following electronic databases were searched from their inception to April 2015: PUBMED, EMBASE and Cochrane Library. Statistical analysis was done using REVIEW MANAGER 5.3. Five RCT involving 739 patients were studied. There were significant differences between the NACT + RS and the RS-alone groups for positive lymph nodes (OR, 0.45; 95%CI: 0.29-0.70) and parametrial infiltration (OR, 0.48; 95% CI: 0.25-0.92), while treatment efficacy did not differ significantly for 5-year overall survival rate (OR, 1.17; 95% CI: 0.85-1.61), 5-year disease-free survival rate (OR, 1.09; 95% CI: 0.77-1.56) or recurrence rate (OR, 1.17; 95% CI: 0.85-1.61). The results also indicated that chemotherapy-related toxicity was well tolerated. For patients with cervical cancer, NACT could significantly reduce the number of positive lymph nodes and the level of parametrial infiltration compared with RS alone, and be well tolerated.

    The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970\\'s. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

    Full Text Available It is known that age is an important factor for postoperative cognitive dysfunction (POCD and the patients with POCD suffer from the impairment of multiple brain regions and multiple brain functions. However currently animal studies of POCD mainly focus on hippocampus region, therefore in this study we performed partial hepatectomy in young adult and aged rats to test the questions (1 whether POCD in animals involves other brain areas besides hippocampus; (2 how age influences POCD of young adult and aged animals. We found that (1 in young adult rats, the memory was not significantly affected (P>0.05 1d, 3d and 7d after partial hepatectomy, but was significantly impaired (p0.05, respectively 1d and 3d post-surgery, but the spine densities at CA1 and DG of aged rats were significant reduced 1d and 3d post-surgery (p0.05; (3 In young adult rats, surgery didn't affect the activation of microglia and levels of TNF-α and IL-1β at hippocampus (P>0.05, but significantly activated microglia and increased levels of TNF-α and IL-1β at hippocampus of aged rats (P<0.05. Our data suggest that (1 partial hepatectomy-induced POCD mainly involves hippocampus impairments, and (2 differential loss of neuronal dendritic spines and neuroinflammation at hippocampus are most likely the mechanism for the formation of POCD in aged rats.

  18. Risk factors for lower-limb lymphedema after surgery for cervical cancer

    International Nuclear Information System (INIS)

    Lower-limb lymphedema (LLL) is a prevalent complication that is encountered after treatment for gynecological malignancies. The aim of this study was to evaluate the risk factors for postoperative LLL in patients with cervical cancer. We conducted a retrospective chart review for patients who had undergone surgery, including systematic lymphadenectomy, for cervical cancer. Patients who died of cancer, were evaluated for short periods of time (<2 years), had missing medical records, or were suffering from deep venous thrombosis were excluded. We utilized the International Society of Lymphology staging of lymphedema severity as the diagnostic criteria for LLL, and patients with stage II or III lymphedema, as objectively determined by physicians, were included in the group of patients with LLL. Multivariate analysis was performed to confirm independent risk factors. A total of 155 patients with cervical cancer were evaluated. Thirty-one patients (20.0%) contracted LLL with a median follow-up of 6.1 years. Suprafemoral node dissection (odds ratio, 9.5; 95% confidence interval, 1.2-73.3; P=0.031) and adjuvant radiotherapy (3.7; 1.2-10.9; P=0.019) were identified as independent risk factors. Given that the effectiveness of the above two therapeutic options for cervical cancer is currently controversial, the clinical benefits of these therapies should be reevaluated specifically to conserve the quality of life for patients with this disease.

    Full Text Available BACKGROUND: CMAC videolaryngoscope has recently been introduced for videoscope guided intubation. The aim of our study was to compare and evaluate the efficacy of the conventional blade and the angulated D blade of the CMAC videolaryngoscope with the direct laryngoscopes in simulated cervical spine injury patients on the airway manikin. MATERIALS AND METHODS: Following power analysis, 33 resident doctors were enrolled to perform endotracheal intubation using all the 4 different laryngoscopes namely the Macintosh laryngoscope, McCoy laryngoscope, conventional CMAC videolaryngoscope and the D blade of the CMAC videolaryngoscopes on the airway manikin in simulated cervical spine injury. The demographic variables of the resident doctors were recorded. The outcomes measured included vocal cord visualization (Cormack-Lehane grading, time taken to intubate, number of attempts for successful intubation and optimizing maneuvers required. RESULTS: The use of indirect videolaryngoscopes resulted in better glottic visualization in comparison to the direct laryngoscopes (CL-I in 20/33 (60.6% in the Macintosh group, 24/33 (72.7% in McCoy group, 30/33 in (90.9% in Vlc group and 32/33 (96.9% in Vld group. The time taken to intubate averaged to 15.54 ± 2.6 in Macintosh group, 18.90 ± 4.47 in McCoy group, 20.21 ± 7.9 in Vlc group and 27.42 ± 9.09 in Vld group. The 1st attempt intubation success rate was 84.8% (Macintosh, 72.7% (McCoy, 90.9% (Vlc and, 78.7% (Vld. CONCLUSIONS: The overall performance of the conventional CMAC blade proved to be the best when compared with the D-blade CMAC, Macintosh blade and the McCoy blade for intubation in simulated cervical spine patients by anesthesia residents.

    Purpose: To assess the efficacy of the BLADE technique to eliminate motion, truncation, flow and other artifacts in Cervical Spine MRI compared to the conventional technique. To study the ability of the examined sequences to reduce the indetention and wrap artifacts, which have been reported in BLADE sagittal sequences. Methods: Forty consecutive subjects, who had been routinely scanned for cervical spine examination using four different image acquisition techniques, were analyzed. More specifically, the following pairs of sequences were compared: a) T2 TSE SAG vs. T2 TSE SAG BLADE and b) T2 TIRM SAG vs. T2 TIRM SAG BLADE. A quantitative analysis was performed using the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and relative contrast (ReCon) measures. A qualitative analysis was also performed by two radiologists, who graded seven image characteristics on a 5-point scale (0:non-visualization; 1:poor; 2:average; 3:good; 4:excellent). The observers also evaluated the presence of image artifacts (motion, truncation, flow, indentation). Results: Based on the findings of the quantitative analysis, the ReCON values of the CSF (cerebrospinal fluid)/SC (spinal cord) between TIRM SAG and TIRM SAG BLADE were found to present statistical significant differences (p<0.001). Regarding motion and truncation artifacts, the T2 TSE SAG BLADE was superior compared to the T2 TSE SAG and the T2 TIRM SAG BLADE was superior compared to the T2 TIRM SAG. Regarding flow artifacts, T2 TIRM SAG BLADE eliminated more artifacts compared to the T2 TIRM SAG. Conclusion: The use of BLADE sequences in cervical spine MR examinations appears to be capable of potentially eliminating motion, pulsatile flow and trancation artifacts. Furthermore, BLADE sequences are proposed to be used in the standard examination protocols based on the fact that a significantly improved image quality could be achieved.

    MRI velocimetry (also known as phase-contrast MRI) is a powerful tool for quantification of cerebrospinal fluid (CSF) flow in various regions of the brain and craniospinal junction and has been accepted as a diagnostic tool to assist with the diagnosis of certain conditions such as hydrocephalus and chiari malformations. Cerebrospinal fluid is continually produced in the ventricles of the brain, flows through the ventricular system and then out and around the brain and spinal cord and is reabsorbed over the convexity of the brain. Any disease process which either impedes the normal pattern of flow or restricts the area where flow occurs can change the pattern of these waveforms with the direction and velocity of flow being determined by the pressure transmitted from the pulsation of the heart and circulation of blood within the central nervous system. Therefore, we hypothesized that phase-contrast MRI could eventually be used as a diagnostic aid in determining the degree of spinal cord compression following injury to the cervical or thoracic spine. In this study, we examined CSF flow in 3 normal subjects and 2 subjects with non-acute injuries in the cervical spine using Cine phasecontrast MRI. CSF flow analysis was performed using an in-house developed software. The flow waveform was calculated in both normal subjects (n=3) as well as subjects with spinal cord injury in the cervical spine (n=2). The bulk flow at C2 was measured to be 0.30 +/- 0.05 cc, at 5 cm distal to C2, it was 0.19+/- 0.07 cc, and at 10 cm distal to C2, it was 0.17+/- 0.05 cc. These results were in good agreement with previously published results. In patients with spinal cord injury, at the site of injury in the cervical spine, bulk flow was found to be 0.08 +/- 0.12 cc, at 5 cm proximal to the site of injury it was found to be 0.18 +/- 0.07 cc, and at 5 cm distal to the site of injury, it was found to be 0.12 +/- 0.01 cc.

    Full Text Available Background: To compare the efficacy and safety of local anaesthetics under cervical epidural anaesthesia (CEA using lignocaine (1%, bupivacaine (0.25% and ropivacaine (0.5% for thyroid surgery. Methods: In a prospective, randomized fashion, 81 patients were selected for thyroid surgery under CEA. They were assigned to one of three groups: Group L, B and R to receive 10 mL of 1% lignocaine, 0.25% bupivacaine and 0.5% ropivacaine, respectively. We compared their efficacy in terms of pulmonary and haemodynamic parameters, blockade quality and complications. Results: Of the total, 74 patients completed the study successfully. Sensory block attained the median dermatomal range of C2-T4/T5 in all the groups. Motor block was more pronounced in the ropivacaine group. Cardiorespiratory parameters decreased significantly in all the groups; however, none of the patients had any major complications except for bradycardia in two patients. Among the measured variables, the decrease in heart rate and peak expiratory force was more in the lignocaine group while forced vital capacity and forced expiratory volume at 1 sec declined to a greater extent in the ropivacaine group. The lignocaine group required significantly more epidural top-ups compared with the other two groups. Conclusion: We conclude that cervical epidural route can be safely used for surgery on thyroid gland in patients with normal cardiorespiratory reserve, using either of local anaesthetics chosen for our study. Under the selected dose and concentrations, the decrease in cardiorespiratory parameters was lesser with bupivacaine.

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

  7. MRI in the assessment of the supportive soft tissues of the cervical spine in acute trauma in children

    International Nuclear Information System (INIS)

    We carried out a retrospective analysis of imaging and clinical findings in 52 children with a history of cervical spinal trauma. No patient had evidence of a fracture on plain films or CT. All had MRI at 1.5 T because of persistent or delayed symptoms, unexplained findings of injury or instability, or as further assessment of the extent of soft-tissue injury. Clinical follow-up ranged from 6 months to 3.5 years. MRI was evaluated for its influence on therapy and outcome. MRI was positive in 16 (31 %) of 52 patients. Posterior soft-tissue or ligamentous injury was the most common finding in the 10 patients with mild to moderate trauma, while acute disc bulges and longitudinal ligament disruption, each seen in one case, were uncommon. MRI was superior to CT for assessment of the extent of soft-tissue injury and for identification of spinal cord injuries and intracanalicular hemorrhage in the six patients with more severe trauma. MRI specifically influenced the management of all four patients requiring surgery by extending the level of posterior stabilization. No patients with normal MRI or any of the 10 with radiographically stable soft-tissue injury on MRI, developed delayed clinical or radiographic evidence of instability or deformity. (orig.)

    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.

  10. Clinical features, outcome and risk factors in cervical cancer patients after surgery for chronic radiation enteropathy

    International Nuclear Information System (INIS)

    Radical hysterectomy and radiotherapy have long been mainstays of cervical cancer treatment. Early stage cervical cancer (FIGO stage IB1–IIA) is traditionally treated using radical surgery combined with radiotherapy, while locally advanced cervical cancer is treated using radiotherapy alone or chemoradiotherapy. In this retrospective study, we describe and analyse the presenting clinical features and outcomes in our cohort and evaluate possible risk factors for postoperative morbidity in women who underwent surgery for chronic radiation enteropathy (CRE). One hundred sixty-six eligible cervical cancer patients who underwent surgery for CRE were retrospectively identified between September 2003 and July 2014 in a prospectively maintained database. Among them, 46 patients received radical radiotherapy (RRT) and 120 received radical surgery plus radiotherapy (RS + RT). Clinical features, postoperative morbidity and mortality, and risk factors for postoperative morbidity were analysed. RS + RT group patients were more likely to present with RTOG/EORTC grade III late morbidity (76.1 % vs 92.5 %; p = 0.004), while RRT group patients tended to show RTOG/EORTC grade IV late morbidity (23.9 % vs 7.5 %; p = 0.004). One hundred forty patients (84.3 %) were treated with aggressive resection (anastomosis 57.8 % and stoma 26.5 %). Overall and major morbidity, mortality and incidence of reoperation in the RRT and RS + RT groups did not differ significantly (63 % vs 64.2 % [p = 1.000], 21.7 % vs 11.7 % [p = 0.137], 6.5 % vs 0.8 % [p = 0.065] and 6.5 % vs 3.3 % [p = 0.360], respectively). However, incidence of permanent stoma and mortality during follow-up was higher in the RRT group than in the RS + RT group (44.2 % vs 12.6 % [p = 0.000] and 16.3 % vs 3.4 % [p = 0.004], respectively). In multivariate analysis, preoperative anaemia was significantly associated with overall morbidity (p = 0.015), while severe intra-abdominal adhesion (p = 0.017), ASA grades III–V (P = 0

    目的:观察可视喉镜下手工中立位全麻气管插管对颈椎颈髓手术患者术中血流动力学以及术后并发症的影响.方法:选择60例全麻手术患者,随机分为两组,每组30例,即直视喉镜组(对照组),手工中立位可视喉镜组(研究组).对两组患者分别使用直视喉镜、手工中立位可视喉镜进行气管插管,比较两组患者首次插管成功率、围插管期血流动力学及术后24h咽喉部并发症发生率.结果:与直视喉镜组比较,可视喉镜组首次插管成功率明显提高(P <0.05)、围插管期血流动力学波动幅度更小(P <0.05),术后咽喉部并发症发生率降低(P <0.05).结论:与直接喉镜相比,手工中立位可视喉镜可以缩短气管插管的用时,改善围插管期血流动力学波动,减轻咽喉部的损伤.%Objective: To investigate the effects of postoperative laryngopharyngeal complications of the patients with cervical spine surgery undergoing tracheal intubation with cervical spine manual-in-line immobilization under videolaryngoscopy. Method: 60 patients requiring general anesthesia were randomly divided into two groups( n = 30 each ), namely, direct laryngoscopy group ( group A ), videolaryngoscopy group ( group B ). Patients were randomly allocated to intubation with videolaryngoscopy or direct laryngoscopy. The number of intubation attempts, hemodynamic parameters and the incidence of postoperative laryngopharyngeal complications were recorded. Result: Compared with group A, patients' airways were successfully managed on the first attempt in group B ( P<0. 05 ), hemodynamic instability were better during intubation ( P<0. 05 ), and the incidence of postoperative laryngopharyngeal complications decreased ( P<0. 05 ). Conclusion : Compared with direct laryngoscopy, cervical spine manual-in-line immobilization under videolaryngoscopy can improve the speed or ease of intubations and attenuate the laryngopharyngeal injury.

    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 ...

    Fertility preservation in young patients with cervical cancer is suitable only for patients with good prognostic factors and disease amenable to surgery without adjuvant therapy. Consequently, it is only offered to patients with early-stage disease (stage IB tumours 2 cm) and lymphovascular space invasion status are two main factors to determine the best fertility-sparing surgical technique. In this systematic Review, we assess six different techniques that are available to preserve fertility (Dargent's procedure, simple trachelectomy or cone resection, neoadjuvant chemotherapy with conservative surgery, and laparotomic, laparoscopic and robot-assisted abdominal radical trachelectomy). The choice between the six different fertility preservation techniques should be based on the experience of the team, discussion with the patient or couple, and, above all, objective oncological data to balance the best chance for cure with optimum fertility results for each procedure.
