Retrospective cohort of 258 consecutive patients. ⋯ Cervical flexion-extension radiographs are a method of assessing potential instability. In the degenerative population studied here, 1% had spondylolisthesis noted only on the flexion-extension images, and 3% had a change in spondylolisthesis. None of these, however, led to a changes in clinical management. These data, in conjunction with the extra cost and radiation exposure associated with additional views, led us to no longer regard dynamic radiographs as a useful part of the initial imaging for the patient with degenerative cervical conditions.

Randomized Controlled Trial Comparative Study
Minimum 5-year follow-up surgical results of post-traumatic thoracic and lumbar kyphosis treated with anterior instrumentation: comparison of anterior plate and dual rod systems.
A retrospective follow-up study of post-traumatic thoracic and lumbar kyphosis after anterior instrumentation with anterior plate and dual rod systems. ⋯ In light of the present study's findings, we suggest that the technique of anterior decompression, strut grafting, and anterior instrumentation is an effective method for the treatment of post-traumatic kyphotic deformity and that the success of the technique depends on the time from trauma to operation and the severity of baseline deformity, regardless of the type of instrumentation.

Randomized Controlled Trial
The efficiency of gabapentin therapy in patients with lumbar spinal stenosis.
Randomized controlled study. ⋯ Based on the results of our pilot study, extensive clinical studies are warranted to investigate the role of gabapentin in the management of symptomatic LSS.

An in vitro human cadaveric biomechanical study. ⋯ In general, CHARITE discs preserved operated- and other-level motions. Fusion simulations affected motion redistribution at other levels, including adjacent levels.
