Comparative StudyEffectiveness of repeated radiofrequency neurotomy for cervical facet joint pain.
Retrospective chart review. ⋯ In a carefully selected group of patients with cervical facet joint pain who have been responsive to previous RFN, repeat RFNs are usually successful.

The effect of parallax on intraoperative positioning of the Charité artificial disc.
Fluoroscopy imaging evaluation for total disc arthroplasty. ⋯ The spinous process is an unreliable anatomic midline marker. In contrast, the borders of the vertebral bodies can more reliably be used to calculate the displacement of the prosthesis from centerline to determine prosthesis position. Fluoroscopic parallax can cause an ideally placed prosthesis to appear more displaced with increasing rotation and distance away from the true anteroposterior image. The spinous process was determined to be an unreliable midline marker. The vertebral borders provided a more dependable anatomic reference point to establish the disc-space midline.

Case report. ⋯ We reported a case of Pisa syndrome in which pleurothotonus occurred after treatment with a tricyclic antidepressant and improved after dose reduction. When middle-aged or elderly patients who see orthopedic surgeons display abnormal postures of the trunk, physicians need to ask the patient whether they have received a drug that can cause Pisa syndrome, such as an antipsychotic or antiemetic.

Comparative StudyFinancial incentives for lumbar surgery: a critical analysis of physician reimbursement for decompression and fusion procedures.
Retrospective case-control study/economic analysis. ⋯ These findings challenge the assertion that spine surgeons have an undue financial incentive to recommend a combined decompression and instrumented fusion procedure over an isolated decompression to patients with symptomatic lumbar degeneration, especially when considering the greater time, effort, and risk characteristic of this more complex operation.
