Prospective clinical study. ⋯ In this study, we evaluated the utility of RSA in evaluating segmental motion after ACDF and demonstrated a significant difference between segments that demonstrated radiographic evidence of fusion when compared with segments that demonstrated evidence of pseudarthrosis. RSA appears to be a quantitative technique capable of assisting in the evaluation of fusion.

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.

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.
