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.

Case report. ⋯ We reported a patient with OPLL who had undergone resurgery twice because of myelopathy due to the progression of ossification. It was important to establish a sufficiently longitudinal and transverse decompression, taking the risk of the unexpected progression of ossification into consideration.

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.

Comparative Study
Comparing cervical spine motion with different halo devices in a cadaveric cervical instability model.
Biomechanical evaluation of conventional and noninvasive halos in cadaveric C1-C2 and C5-C6 instability models. ⋯ Donning of the NIH generates significantly less cervical spine motion than application of the CH. The CH provides superior immobilization for a C5-C6 instability during the log roll maneuver and a C1-C2 instability in the frontal plane during the log-roll maneuver. The CH and NIH immobilize the C1-C2 and C5-C6 instability to a similar degree during the sit-up maneuver.
