Measurements and mapping of 282,420 nerve fibers in the S1-5 nerve roots.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions The B fibers represented efferent parasympathetic fibers. These fibers were concentrated in certain areas of the nerve roots, not randomly distributed. The Aalpha fibers innervate lower-extremity muscles and sphincters. The inverse correlation of Aalpha and Agamma fibers in the ventral roots from S-1 to S-5 is surprising. In dorsal roots, Agamma fibers may conduct pain, touch, and temperature signals. Highly selective fiber stimulation specific for type, location, and direction may improve sacral nerve stimulation for a spastic bladder in paraplegic individuals.

Mean subaxial space available for the cord index as a novel method of measuring cervical spine geometry to predict the chronic stinger syndrome in American football players.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions A critical value of 5.0 mm for the MSCSAC provides the clinician with a screening test for chronic stingers and anything < 4.3 mm adds additional confidence as a confirmatory test. These results are ~ 20% more accurate than the classic Torg ratio based on our AUC analysis. It was found that measuring the spinal geometry throughout the length of the subaxial cervical spine produced a more reliable method by which to predict neurological symptoms than the traditional approach of measuring individual levels. This shows that the underlying pathogenesis of the chronic stinger syndrome is best characterized as a p...

Thoracic vertebrectomy and spinal reconstruction via anterior, posterior, or combined approaches: clinical outcomes in 91 consecutive patients with metastatic spinal tumors.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Decisions regarding the approach to thoracic vertebrectomy may be complex. This study found that although anterior approaches to the thoracic vertebrae have been historically associated with significant pulmonary complications, in our experience these rates are nevertheless quite comparable to that encountered via a posterior or combined approach. In fact, the posterior approach was found to be associated with a higher risk for some perioperative complications such as wound infection and deep vein thromboses. Finally, the combined anteriorposterior approach may provide greater ambulatory and neurological improv...

Staged sacrectomy-an adaptive approach.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Sacrectomy, a dreaded operation that often results in morbidity, is now feasible with modifications and improvement in surgical technique. The staged abdominosacral approach reduces the immediate postoperative morbidity. Use of a gluteal advancement flap reduces the incidence of wound complications. With modern surgical facilities and postoperative care, sacrectomy is feasible via the staged abdominosacral approach. PMID: 19769509 [PubMed - in process] (Source: Journal of Neurosurgery.Spine)

Comparison of thoracolumbosacral orthosis and no orthosis for the treatment of thoracolumbar burst fractures: interim analysis of a multicenter randomized clinical equivalence trial.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions This interim analysis found equivalence between treatment with a TLSO and no orthosis for thoracolumbar AO Type A3 burst fractures. The influence of a brace on early pain control and function and on long-term 1- and 2-year outcomes remains to be determined. However, the authors contend that a thoracolumbar burst fracture, in exclusion of an associated posterior ligamentous complex injury, is inherently a very stable injury and may not require a brace.

Neurological outcome after surgical management of adult tethered cord syndrome.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions In the authors' experience, pain and motor and urinary dysfunction improve postoperatively in the majority of patients. The rate of symptomatic improvement was greatest for pain resolution, followed by motor, and then urinary improvement. Patients who experienced improvement in any symptom had done so by 6 months after tethered cord release. Patients with asymmetrical motor symptoms or lower extremity hyperreflexia at presentation were most likely to experience improvements in motor symptoms. These findings may help guide patient education and surgical decision-making. PMID: 19769511 [PubMed - in process] (...

Management of delayed esophageal perforations after anterior cervical spinal surgery.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions The authors recommend a multidisciplinary approach that involves otolaryngological surgeons as well as spine surgeons. They recommend removal of all anterior hardware and believe that it is essential to the treatment of esophageal perforations. If the patient does not have evidence of fusion at the time of presentation, then posterior cervical instrumentation is a viable alternative.

Positional vertebral artery compression and vertebrobasilar insufficiency due to a herniated cervical disc.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The authors report a case of vertebrobasilar insufficiency caused by vertebral artery (VA) compression due to a herniated cervical disc, which was surgically treated with the aid of intraoperative angiography. This 78-year-old man visited the hospital because of syncope following head rotation. Admission CT scans revealed a calcified mass adjacent to the right lateral process of the C-4 spine. Cervical angiography demonstrated an obstruction of the right VA at this region on rotation of the head to the right. The operation revealed a cervical disc protruding toward the right VA. The disc was surgically removed, and the...

Anterior and posterior decompressive surgery for progressive amyotrophy associated with cervical spondylosis: a retrospective study of 51 patients.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Surgical outcome in patients with distal muscle atrophy was inferior to that in patients with proximal atrophy. The distal type was characterized by a long preoperative period, a greater number of cervical spine misalignments, a narrow spinal canal, and increased signal intensity on T2-weighted MR imaging. It is essential to perform a careful neurological evaluation, including sensory examination of the lower limbs, as well as neuroradiological and neurophysiological assessments to avoid confusion with motor neuron disease and to detect the coexistence of amyotrophic lateral sclerosis, especially when surgical ...

Iatrogenic intradural spinal arachnoid cyst as a complication of lumbar spine surgery.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Iatrogenic spinal arachnoid cysts are rare, but have been described as a complication of spinal injection and lumbar puncture procedures. The authors describe 2 cases of iatrogenic spinal arachnoid cyst formation that occurred after incidental durotomy during lumbar spine surgery. In both cases, postoperative MR imaging revealed compression of the cauda equina by an intradural arachnoid cyst. Intradural exploration and fenestration of the arachnoid cyst was accomplished in each case. This entity should be considered in the differential diagnosis of a patient experiencing symptoms of neurological compression after a lum...

Traumatic burst fracture in a patient with a lumbar artificial disc.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Lumbar disc arthroplasty is now a common treatment for lumbar degenerative disc disease. Whereas the immediate and delayed complications in patients with artificial lumbar discs are well reported, the durability of artificial disc hardware after severe spine trauma is unknown. The authors describe the management of a rare case of a traumatic lumbar burst fracture in a patient who had undergone disc arthroplasty. This 31-year-old male contractor had undergone placement of an L4-5 Charité artificial disc (DePuy Spine) and L5-S1 anterior lumbar fusion 10 months before he fell from a roof and sustained a traumatic L-3...

Epidural steroid injection resulting in epidural hematoma in a patient despite strict adherence to anticoagulation guidelines.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Epidural steroid injections are relatively safe procedures, although the risk of hemorrhagic complications in patients undergoing long-term anticoagulation therapy is higher. The American Society for Regional Anesthesia and Pain Medicine has specific guidelines for treatment of these patients when they undergo neuraxial anesthetic procedures. In this paper, the authors present a case in which the current American Society for Regional Anesthesia and Pain Medicine guidelines were strictly followed with respect to withholding and reintroducing warfarin and enoxaparin after an epidural steroid injection, but the patient ne...

Complications in the management of Charcot spinal arthropathy.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Charcot spinal arthropathy is a relatively rare, destructive process characterized by a cycle of progressive deformity, destruction, and worsening instability as a result of repetitive trauma and inflammation. It may result from nontraumatic as well as traumatic causes. Historically, patients with severe symptomatic instability have been successfully treated with combined anterior and posterior fusion techniques. The long-term outcomes and potential complications, however, have not been well reported. The authors report on 2 such cases of Charcot spinal arthropathy treated surgically, one with a traumatic and one with ...

Electromyography in the detection of mechanically induced spinal motor tract injury: observations in diverse porcine models.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Electromyographic activity (referred to as "EMG injury discharges" in the present study) can be elicited both by intramedullary manipulation and rapidly applied transaxial spinal cord compression. Preliminary observations suggest that these EMG injury discharges precede and may anticipate TcMEP loss. Presumably, rapid deformation of spinal motor tracts (which appear to lie within the lateral porcine spinal cord) generates descending volleys which can bring to firing threshold lumbar motor neurons (and recording of EMG injury discharges). Intraoperative neuromonitoring of high-risk spinal surgeries at the spinal...

Conclusions Treatment of mild CSM may involve surgical decompression or nonoperative therapy for the first 3 years after diagnosis. More severe CSM (mJOA scale score </= 12) should be considered for surgery depending upon the individual case. The shortcomings of this systematic review are that the group was not able to determine whether an mJOA scale score of 12 was indicative of a more severe CSM disease course, and whether patients who received nonsurgical treatment for 3 years had a significant probability for clinical deterioration after that time point.

Conclusions Although the use of EP monitoring may serve as a sensitive means to diagnose potential neurological injury during anterior spinal surgery for cervical spondylotic myelopathy, the practitioner must understand that intraoperative EP worsening is not specific-it may not represent clinical worsening and its recognition does not necessarily prevent neurological injury, nor does it result in improved outcome (Class II). Intraoperative improvement in EP parameters/indices does not appear to forecast outcome with reliability (conflicting Class I data).

Posterior fixation in the reduced dislocation position forms the basis of treatment. PMID: 19569934 [PubMed - in process] (Source: Journal of Neurosurgery.Spine)

Radiographic and clinical evaluation of free-hand placement of C-2 pedicle screws.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Free-hand placement of screws in the C-2 pedicle can be done safely and effectively without the use of intraoperative fluoroscopy or navigation when the pars interarticularis/pedicle is assessed preoperatively with CT or MR imaging and found to be suitable for screw placement. When breaches do occur, they are overwhelmingly lateral in location, breach < 50% of the screw diameter, and in the authors' experience, are not clinically significant.

Revision characteristics of cement-augmented, cannulatedfenestrated pedicle screws in the osteoporotic vertebral body: a biomechanical in vitro investigation.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In generalized osteoporosis, instrumentation with cement-augmented pedicle screws is an amplification of the therapeutic spectrum. Early clinical results are promising for both solid and cannulated screws; however, there are concerns regarding the revision characteristics of these screws, especially for the cannulated-fenestrated type with its continuous cement interconnection from the core of the screw to surrounding bone tissue. In a human cadaver model, bone mineral density (BMD) was assessed radiographically. Spinal levels T9-L4 were instrumented left unilaterally, transpedicularly by using cannulated-fenestrated p...

Using lamina screws as a salvage technique at C-7: computed tomography and biomechanical analysis using cadaveric vertebrae.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions These results suggest that using lamina screws as a salvage technique at C-7 provides similar fixation strength as the index pedicle screw. The C-7 lamina appears to have an ideal anatomical width for the insertion of 3.5-mm screws commonly used for cervical fusions. Therefore, if the transpedicular screw fails, using intralaminar screws appear to be a biomechanically sound salvage technique.

Epidemiology of severe cervical spinal trauma in the north area of São Paulo City: a 10-year prospective study.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Data from severe CST observed in the current study suggest many differences in the characteristics described in the majority of published epidemiological studies and those found in patients in the north area of São Paulo City. It is likely that these differences reflect the urban and cultural habits and behaviors of the population specific to this area.

Unusual sequestered disc fragments simulating spinal tumors and other space-occupying lesions.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Atypically located disc herniations should be considered in the differential diagnosis in patients with MR imaging data indicating spinal space-occupying disorders. All of these lesions, even those intradurally located, can be completely removed. PMID: 19569939 [PubMed - in process] (Source: Journal of Neurosurgery.Spine)

An unusual presentation of a solitary benign giant neurofibroma.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The authors report on a 34-year-old man who presented with acute enlargement of an extraspinal mass secondary to a hemorrhage following minor trauma. The mass had been present from birth, had slowly enlarged over time, and previous imaging had suggested an extraspinal fibrolipoma measuring 10 x 6 x 4 cm. Following minor trauma (scratching the skin overlying the tumor), the mass rapidly enlarged to approximately double in size over a period of 4 hours. A CT scan and MR imaging confirmed an extraspinal tumor that was 15 x 11 x 11 cm, with an associated acute hematoma of similar dimensions. The patient was taken to the op...

Symptomatic osteochondroma of the spine in elderly patients.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this report, the authors show that pathological accelerating bone turnover such as psoriatic arthritis may be a possible mechanism for the onset of the enlargement of osteochondromas in elderly patients. The age of the patients in this report suggests that growth of the osteochondroma continues after skeletal development. PMID: 19569943 [PubMed - in process] (Source: Journal of Neurosurgery.Spine)
