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.

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.

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
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.

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.
