Clinical, radiographic, and outcomes assessment focusing on neurologic complications in patients undergoing pedicle subtraction osteotomy (PSO). Clinical data were collected prospectively. Radiographic analysis was performed retrospectively. ⋯ Intraoperative or postoperative neurologic deficits are relatively common following a PSO; however, in a majority of cases, deficits are not likely to be permanent.

We evaluated electrophysiologic changes of the cauda equina after lumbar laminotomy in rats. ⋯ SSEP is valuable for detecting electrophysiologic changes after laminotomy fibrosis, but acceptable accuracy requires proper stimulation and recording settings. D-SSEP monitoring provided reliable, useful information about the functional integrity of the cauda equina in this animal model. We recommend D-SSEP monitoring as a supplemental tool for quantifying the effect of postlaminotomy fibrosis on neuropathy.

Randomized Controlled Trial Multicenter Study
Fear avoidance beliefs do not influence disability and quality of life in Spanish elderly subjects with low back pain.
Correlation between previously validated questionnaires. ⋯ In Spanish institutionalized elderly subjects, FABs only have a minor influence on physical quality of life, and none on disability or mental quality of life. In elderly subjects with LBP, differences in FABs are not associated with differences in disability or quality of life. Further studies should explore the potential value of FABs in the elderly in other settings.

Randomized Controlled Trial Multicenter Study
Are back supports plus education more effective than education alone in promoting recovery from low back pain?: Results from a randomized clinical trial.
Randomized clinical trial. ⋯ Although there was no overall effect on self-reported recovery or administrative measures or lost work time between the study groups, a back support plus health education may have some value in preventing recurrent WR-LBD in industrial workers who work in psychosocial environments and perform manual material handling tasks similar to those found in parts distribution centers.
