Here the authors report the case of a fresh vertebral body fracture with a large spinal intraosseous arteriovenous fistula (AVF). A 74-year-old woman started to experience low-back pain following a rear-end car collision. Plain radiography showed diffuse idiopathic skeletal hyperostosis (DISH). ⋯ The spinal intraosseous AVF had disappeared after 4 months. At 24 months after surgery, the bone defect was completely replaced by bone and the patient experienced no limitations in daily activities. Given their experience with the present case, the authors believe that performing vertebroplasty or anterior reconstruction may not be necessary in treating spinal intraosseous AVF.

Surgical decompression is the intervention of choice for lumbar spinal stenosis (LSS) when nonoperative treatment has failed. Standard open laminectomy is an effective procedure, but minimally invasive laminectomy through tubular retractors is an alternative. The aim of this retrospective case series was to evaluate the clinical and radiographic outcomes of this procedure in patients who underwent LSS and to compare outcomes in patients with and without preoperative spondylolisthesis. ⋯ Minimally invasive laminectomy is an effective procedure for the treatment of LSS. Reoperation rates for instability are lower than those reported after open laminectomy. Functional improvement is similar in patients with and without preoperative spondylolisthesis. This procedure can be an alternative to open laminectomy. Routine fusion may not be indicated in all patients with LSS and spondylolisthesis.

C-5 palsy after cerebrospinal fluid diversion in posttraumatic syringomyelia: case report.
Syringomyelia is a potentially debilitating disease that involves abnormal CSF flow mechanics; its incidence after traumatic spinal cord injury (SCI) is approximately 15%. Treatment consists of restoration of CSF flow, typically via arachnoidolysis and syrinx decompression. The authors present a case of pronounced syringomyelia in a patient with concomitant severe cervical myelomalacia to demonstrate unilateral C-5 palsy as a potential complication of aggressive syrinx decompression at a remote level. ⋯ Further motor recovery was noted at the 8-month follow-up. Syringomyelia is a debilitating disease arising most often as a result of traumatic SCI. In the setting of myelomalacia with a pronounced syrinx, C-5 palsy is a potential complication of syrinx decompression.

Spinal cord ischemia remains a serious complication of thoracoabdominal aortic aneurysm surgery. Coenzyme Q10, a potent antioxidant, has been reported to exert a neuroprotective effect. In the present study, we evaluated the effect of coenzyme Q10 pretreatment on spinal cord ischemia-reperfusion injury. ⋯ Pretreatment with 300 mg/kg coenzyme Q10 resulted in significantly improved neurological function and preservation of more normal motor neurons.

The object of this study was to describe the authors' method of anterior discectomy/corpectomy and fusion combined with internal fixation for the treatment of unstable hangman's fractures and to evaluate the clinical and radiological outcomes. ⋯ Anterior discectomy/corpectomy and fusion combined with internal fixation is a safe and effective procedure for the treatment of unstable hangman's fractures.
