An in vivo rat model of transient cervical nerve root compression. ⋯ Results imply a force threshold exists less than 10 gf for persistent pain symptoms following transient cervical nerve root compression. Findings also suggest that spinal glial activation may be related to behavioral sensitivity and may modulate cervical nerve root mediated pain.

A retrospective study was performed to identify horizontal fractures of the body of the axis, with special attention to their pattern, prevalence, and clinical outcome. ⋯ Horizontal fractures of the Chance-type of the body of the axis are rare. Conservative treatment proved to be effective.

The authors provide their results in performing multilevel oblique corpectomy for degenerative spondylotic myelopathy in 48 patients. ⋯ Multilevel oblique corpectomy was found to be a safe technique that guarantees good results in terms of both regression of clinical symptoms and long-term spinal stability.
-
Retrospective clinical study from 2 centers. ⋯ Using posterior surgery only, we have been able to at least equal the results reported in the literature by investigators using combined approaches. Isolated posterior instrumentation and arthrodesis achieve satisfactory cosmetic, radiographic, and patient-based outcomes in adolescents with idiopathic scoliosis with thoracic curves 70 degrees-90 degrees, without the added expense and morbidity of anterior release.

Case Reports
Somatosensory evoked potential monitoring during anterior cervical discectomy and fusion.
A retrospective, multicenter clinical review was conducted. ⋯ In no instance were positive SSEP findings clinically useful in alerting the surgeon to potential intraoperative complications. Intraoperative SSEP monitoring is not helpful to the surgeon when performing routine ACDF. Additionally, ACDF is a safe procedure with a low rate of neurologic complications.
