Comparative Study
Comparison of the flat torso versus the elevated torso shoulder pad removal techniques in a cadaveric cervical spine instability model.
Controlled laboratory study in a cadaveric model. ⋯ These findings support use of the elevated torso method to minimize cervical spine motion during shoulder pad removal when neither thoracic nor lumbar spinal injury is a concern.

Randomized Controlled Trial Comparative Study
Magnetic resonance imaging interpretation in patients with symptomatic lumbar spine disc herniations: comparison of clinician and radiologist readings.
Retrospective review of imaging data from a clinical trial. ⋯ Radiology reports frequently fail to provide sufficient detail to describe disc herniation morphology. Agreement between MRI readings by clinical spine specialists and radiologists was excellent when comparing herniation vertebral level and location within level, but only fair comparing herniation morphology.

Review Case Reports
Delayed hyper-reactivity to metal ions after cervical disc arthroplasty: a case report and literature review.
Anecdotal case report. ⋯ Although there is increased enthusiasm about motion preservation technology and disc replacement surgery for intervertebral disc herniation, unexpected complications like the present case need to be shared within the scientific community to better understand the risks associated with these new and promising devices.

Prospective longitudinal study, mean follow-up period; 11.7 +/- 0.8 years was conducted from 1995 to 2007. ⋯ Progression of degeneration of cervical spine on MRI was frequently observed during 10-year period, with development of symptoms in 34% of subjects. No factor related to progression of degeneration of cervical spine was identified except for age.
