Comparative Study
A criterion measure of walking capacity in lumbar spinal stenosis and its comparison with a treadmill protocol.
Measurement (validity) study. ⋯ The SPWT is presented as a feasible and reproducible criterion measure of walking capacity for use with LSS patients. Although a strong relationship was demonstrated between the treadmill protocol and the SPWT, a systematic bias was observed with patients walking significantly further in the SPWT (36% in mean).

Case Reports
Spine-shortening vertebral osteotomy for tethered cord syndrome: report of three cases.
Retrospective case series. ⋯ Spine-shortening vertebral osteotomy can be a safe and alternative surgical technique for tethered cord syndrome.

Retrospective radiographic review. ⋯ Although disc height, translational motion, and angular variation are significantly affected at the level of a disc herniation, no significant changes are apparent in adjacent segments. Our results indicate that herniated discs have no effect on ROM at adjacent levels regardless of the degree of disc degeneration or the size of disc herniation, suggesting that the natural progression of disc degeneration and adjacent segment disease may be separate, unrelated processes within the cervical spine.

A retrospective evaluation. ⋯ Adult spinal deformity patients with preoperative hypolordosis who were positioned prone during reconstructive surgery had an enhanced lumbar lordosis via positioning alone compared with theirpreoperative upright radiographs. Conversely, those with substantial preoperative lordosis remained unchanged with intraoperative prone positioning. This knowledge will help in the surgical planning of adult spinal deformity reconstructive surgery to optimize sagittal alignment and balance.
