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
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.

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.

Comparative Study
A new stand-alone cervical anterior interbody fusion device: biomechanical comparison with established anterior cervical fixation devices.
A new anchored spacer-a low-profile cervical interbody fusion cage with integrated anterior fixation-was compared biomechanically to established anterior cervical devices. ⋯ The anchored spacer provided a similar biomechanical stability to that of the established anterior fusion technique using an anterior plate plus cage and has a potentially lower perioperative and postoperative morbidity. These results support progression to clinical trials using the cervical anchored spacer as a stand-alone implant.

An in vitro biomechanical study. ⋯ The halo-vest, applied normally, effectively immobilized the cervical spine. Sagittal or frontal plane snaking of the cervical spine due to the halo-vest may reduce its immobilization capability at the upper cervical spine and cervicothoracic junction.
