Multicenter Study Comparative Study
A low back-specific version of the SF-36 Physical Functioning scale.
A prospective repeated measures design was used to produce a back-specific version of the Short Form-36 Physical Functioning scale (SF-36 PF) by Rasch analysis of a pool of items from the SF-36 PF, Oswestry Disability Questionnaire, and the Quebec Back Pain Disability Scale. ⋯ The Low-Back SF-36 PF18 comprises the 10-item SF-36 PF scale and four items each from the Oswestry and Quebec back pain questionnaires. The possible total score ranges from 0 to 100, with a higher score indicating better function. The new scale appears to offer advantages over the use of the original scale for the assessment of functioning in patients with low back pain.

Retrospective clinical and radiographic review with functional outcome assessment. ⋯ Satisfactory results are achieved with selective thoracic fusion of properly selected C modifier lumbar curves. Correction of the lumbar curve results principally from a decrease in the tilt of its upper vertebrae, but not necessarily improved apical translation. Mild coronal imbalance was well tolerated and has not necessitated distal extension of the fusion.

Comparative Study Clinical Trial
Ne-Osteo bone growth factor for posterolateral lumbar spine fusion: results from a nonhuman primate study and a prospective human clinical pilot study.
Prospective animal and human clinical pilot trial. ⋯ A graft composite of Ne-Osteo bone growth factor with human DBM with or without cancellous allograft or local bone autograft was capable of achieving a contiguous spine fusion mass in 15 of 16 patients at a dose of at least 25 mg per side. This result was comparable with the results using iliac crest autograft (94%) in this side-by-side model. These results warrant confirmation in a definitive trial using Ne-Osteo on both sides of the spine and thus avoiding the need for iliac crest bone graft harvest.

Comparative Study
Weight-bearing radiographs in thoracolumbar fractures: do they influence management?
Prospective observational study. ⋯ Performing erect radiographs in patients with thoracolumbar fractures without a neurologic deficit provides additional information and did alter the management plan in a significant proportion (25%) of our patients.
