Case Reports
Spinal dural arteriovenous fistula with hematomyelia caused by intraparenchymal varix of draining vein.
Hemorrhage that results from spinal dural arteriovenous fistula (Type I arteriovenous malformation [AVM]) is uncommon. There are some reports of subarachnoid hemorrhage and subdural hematoma caused by Type I spinal AVM, but there are few reported cases of hematomyelia caused by spinal dural arteriovenous fistula. ⋯ It must be kept in mind that spinal dural arteriovenous fistulas (Type I spinal AVM) has possibility of hematomyelia origin, despite the fact that it is extremely rare.

A variety of orthoses are routinely applied after spinal procedures but there are limited data regarding their efficacy, especially with the increasing use of internal fixation. At this time, the proper indications for postoperative bracing are not well established. ⋯ Although most of the respondents brace their patients postoperatively, there is an obvious lack of consensus regarding the most appropriate type, duration, and indications for immobilization. Further prospective, clinical studies may play a helpful role in evaluating the efficacy of postoperative bracing protocols.

Previous publications have reported results with respect to functional outcome and sexual function in young women after traumatic injuries to the pelvis. It is well known that anterior spinal surgery has the possibility of causing reproductive dysfunction in men. Little has been described concerning deleterious effects of anterior spinal surgery in women of childbearing age. ⋯ Although the cesarean-section rate appears high, it is consistent with the current obstetrical trends. Anesthesiologists appear less inclined to offer neuraxial anesthesia to a population which has undergone anterior spinal surgery.

Randomized Controlled Trial Multicenter Study Comparative Study
Results of the prospective, randomized, controlled multicenter Food and Drug Administration investigational device exemption study of the ProDisc-C total disc replacement versus anterior discectomy and fusion for the treatment of 1-level symptomatic cervical disc disease.
Cervical total disc replacement (TDR) is intended to address radicular pain and preserve functional motion between two vertebral bodies in patients with symptomatic cervical disc disease (SCDD). ⋯ The results of this clinical trial demonstrate that ProDisc-C is a safe and effective surgical treatment for patients with disabling cervical radiculopathy because of single-level disease. By all primary and secondary measures evaluated, clinical outcomes after ProDisc-C implantation were either equivalent or superior to those same clinical outcomes after Fusion.

Multicenter Study
Do 1-year outcomes predict 2-year outcomes for adult deformity surgery?
Health-related quality-of-life (HRQOL) measures are being used more frequently in the evaluation of the adult deformity patient. This is due in part to the validation of the deformity-specific Scolios Research Society-22 (SRS-22). Hence, relationships between HRQOL outcomes and traditional measures of success such as deformity correction, fusion healing, and complications are being established. ⋯ This study supports the application of HRQOL measures, including the deformity-specific SRS-22, as a valuable tool in the assessment of adult deformity patients. Change in outcome score stabilized after the 1-year postoperative interval, for most patients.
