Case Reports
Polymethylmethacrylate cement dislodgment following percutaneous vertebroplasty: a case report.
A case report is presented. ⋯ This complication is rare and likely to occur in treatment of osteoporotic vertebral fracture with avascular necrosis and anterior cortical defect.

Case Reports Comparative Study
Minimally invasive surgery for ablation of osteoid osteoma of the spine.
Compare the effectiveness of two different techniques for the management of osteoid osteoma of the spine. ⋯ Minimally invasive surgery can successfully be applied in the treatment of osteoid osteoma of the lumbar spine. When the nidus is not adjacent to the neural elements radiofrequency thermal ablation can be an effective and safe treatment of osteoid osteoma in the spine.

A retrospective review of patient outcomes after lumbar spinal fusion. ⋯ This retrospective review of patients who underwent lumbar fusion for degenerative instability demonstrated no adverse impact on clinical outcomes when the lumbar fusion ended adjacent to a degenerative motion segment. Although a power analysis validated these results with 98% certainty, larger prospective studies are needed to confirm that there is no benefit to include degenerated adjacent segments in a lumbar fusion for degenerative instability.

Reliability study of computed tomography imaging in 12 cadaver specimens instrumented with titanium or stainless steel thoracic pedicle screws. ⋯ Our data show that interobserver agreement is moderate and intraobserver agreement is substantial when computed tomography is used to assess placement of thoracic pedicle screws. We conclude that computed tomography is reliable for evaluating thoracic pedicle screw placement throughout the thoracic spine.

Three previous reviews have reached conflicting conclusions regarding the efficacy of antidepressants for patients with back pain. ⋯ Based on a small number of studies, tricyclic and tetracyclic antidepressants appear to produce moderate symptom reductions for patients with chronic low back pain. This benefit appears to be independent of depression status. SSRIs do not appear to be beneficial for patients with chronic low back pain. There is conflicting evidence whether antidepressants improve functional status of patients with chronic low back pain.
