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.

Randomized Controlled Trial
Efficacy of a patient-educational booklet for neck-pain patients with workers' compensation: a randomized controlled trial.
A randomized controlled trial of an educational booklet for patients with first-time neck pain. ⋯ This study demonstrates that the educational booklets studied were not associated with improved outcomes in patients with neck pain receiving workers' compensation. Whether these results would apply to a nonworkers' compensation population requires further study. The loss of many patients to follow-up also makes any other firm conclusions more difficult to determine.

Comparative Study
Video-assisted anterior thoracoscopic spinal fusion versus posterior spinal fusion: a comparative study utilizing the SRS-22 outcome instrument.
Retrospective, matched cohort. ⋯ Based on the SRS-22 questionnaire data, the VATS patients scored higher in the self-image, mental health, and total domains despite similar curve corrections. We hypothesize that this may be related to the smaller surgical scar and less invasive nature of VATS.
