A case report is presented involving a subdural hematoma after cervical epidural steroid injection. ⋯ It is important to acknowledge that spinal hematomas can occur after cervical epidural steroid injection, as prompt recognition and treatment could improve the prognosis for recovery. The sequelae of a cervical subdural hematoma after epidural steroid injection remain potentially devastating.

Clinical Trial
Clinical outcome results of pedicle subtraction osteotomy in ankylosing spondylitis with kyphotic deformity.
A prospective study was performed in 45 patients with ankylosing spondylitis. ⋯ Most of the patients maintained good correction and had good clinical results. Based on the results of this study, pedicle subtraction extension osteotomy is effective for correction of kyphotic deformity in ankylosing spondylitis.

Meta Analysis
Efficacy of the transcutaneous electrical nerve stimulation for the treatment of chronic low back pain: a meta-analysis.
Low back pain affects a large proportion of the population. Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as an alternative therapy to pharmacologic treatments for chronic pain. However, despite its widespread use, the efficacy of TENS is still controversial. ⋯ The results of the meta-analysis present no evidence to support the use or nonuse of TENS alone in the treatment of chronic low back pain. Considering the small number of studies responding to the criteria to be included in this meta-analysis, it is clear that more appropriately designed studies are needed before a final conclusion. Clinicians and researchers should consistently report the characteristics of the TENS device and the application techniques used. New trials on TENS should make use of standardized outcome measures. This meta-analysis lacked data on how TENS efficacy is affected by four important factors: type of applications, site of application, treatment duration of TENS, and optimal frequencies and intensities.

Some complications of common treatment schemes of thoracolumbar spine fractures can be predicted with magnetic resonance imaging: prospective study of 53 patients with 71 fractures.
Prospective cohort study. ⋯ An unfavorable outcome in the conservative group was related to the progression of kyphosis, which in most cases was predictable with the use of trauma MRI findings concerning the endplate comminution and vertebral body involvement. In the operatively treated group, recurrence of the kyphotic deformity was predictable by the lesion of the posterior longitudinal ligamentary complex together with endplate comminution and vertebral body involvement as seen on trauma MRI. The authors recommend the use of MRI to develop reliable prognostic criteria for these injuries.

An anatomic study of the associations between the fifth lumbar spinal nerve (L5 spinal nerve) and a lumbosacral tunnel, consisting of the fifth lumbar vertebral body (L5 vertebral body), the lumbosacral ligament, and sacral ala, and clinical case reports of four patients with lumbar radiculopathy secondary to entrapment of the L5 spinal nerve in the lumbosacral tunnel. ⋯ Extraforaminal entrapment of L5 spinal nerve in the lumbosacral tunnel can cause L5 radiculopathy, and osteophytes of L5-S1 vertebral bodies are a major cause of the entrapment.
