Randomized Controlled Trial Multicenter Study Comparative Study
The efficacy of prostaglandin E1 derivative in patients with lumbar spinal stenosis.
Randomized controlled trial. ⋯ In this study, limaprost was found to be efficacious on most outcome measures, such as HRQOL, symptoms and subjective satisfaction, in LSS patents with cauda equina symptoms.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of BRYAN cervical disc arthroplasty with anterior cervical decompression and fusion: clinical and radiographic results of a randomized, controlled, clinical trial.
A prospective, randomized, multicenter study of surgical treatment of cervical disc disease. ⋯ Two-year follow-up results indicate that cervical disc arthroplasty is a viable alternative to anterior cervical discectomy and fusion in patients with persistently symptomatic, single-level cervical disc disease.

Randomized Controlled Trial Comparative Study
Suitability of a calcium phosphate cement in osteoporotic vertebral body fracture augmentation: a controlled, randomized, clinical trial of balloon kyphoplasty comparing calcium phosphate versus polymethylmethacrylate.
A prospective randomized controlled clinical study. ⋯ The routine use of the CaP tested is not currently recommended for kyphoplasty. Because of its low resistance against flexural, tractive, and shear forces compared to PMMA, in certain constellations (burst fractures), there is a higher risk of cement failure and subsequent loss of correction.

Case Reports
Bacteremia coexisting with tophaceous gout of the spine mimicking spondylodiscitis: a case report.
A case report and review of the literature. ⋯ This is, to our knowledge, the first case of bacteremia coexisting with multiple areas of tophaceous gout of the spine. Although uncommon, gouty spine should be added into the differential diagnosis of patients with back pain and bacteremia.

Randomized Controlled Trial Multicenter Study
Predictors of outcome after anterior cervical discectomy and fusion: a multivariate analysis.
Retrospective cohort study. ⋯ We found that important predictors of outcome were work status, sensory function, involvement in litigation, and higher disability scores.
