Comparative Study
Subtotal corpectomy versus laminoplasty for multilevel cervical spondylotic myelopathy: a long-term follow-up study over 10 years.
A retrospective study was conducted. ⋯ Subtotal corpectomy and laminoplasty showed an identical effect from a surgical treatment for multilevel cervical spondylotic myelopathy. These neurologic recoveries usually last more than 10 years. In the subtotal corpectomy group, the disadvantages were longer surgical time, more blood loss, and pseudarthrosis. In the laminoplasty group, axial pain occurred frequently, and the range of motion was reduced severely.

A prospective study was conducted to examine bone graft donor site morbidity in 106 consecutive patients undergoing posterior spinal fusion. ⋯ According to this study, it is reasonable to reassure patients that a good result from spinal surgery will not be compromised by severe symptoms or major morbidity secondary to posterior iliac crest bone graft donation. Before surgery, patients may be advised concerning the risks of donor site pain, which improves significantly by 12 months, local tenderness, and uncommonly localized sensory loss.

Case report and literature review. ⋯ Neurologic complications of methylmethacrylate vertebroplasty necessitate active involvement of spine surgeons in patient evaluation and management.

Total excision of a large dumbbell cervicothoracic intra- and extraspinal meningioma that had grown into the posterior mediastinum is described. This excision involved a two-step neurosurgical-thoracosurgical procedure within a short interval. ⋯ The authors recommend a two-staged procedure for complete excision of a large spinal-thoracic meningioma. Even in elderly patients with major neurologic deficits, an impressive recovery can be achieved with such lesions.

Randomized Controlled Trial Clinical Trial
Radiofrequency facet joint denervation in the treatment of low back pain: a placebo-controlled clinical trial to assess efficacy.
A prospective double-blind randomized controlled trial was performed. ⋯ Although radiofrequency facet joint denervation may provide some short-term improvement in functional disability among patients with chronic low back pain, the efficacy of this treatment has not been established.
