This was a retrospective cohort study using a previously matched convenience sample of 34 patients. ⋯ There was no statistically significant difference comparing the 2 groups, although a trend was observed toward better correction of the main thoracic curve in the all-screw construct group. The all-screw group demonstrated a significant decrease in kyphosis, which was not seen in the hybrid group. Hybrid constructs were comparable to all-screw constructs in the correction of coronal plane deformity and sagittal balance.

A cross-sectional observational study to determine the response distribution, internal consistency, and construct, concurrent, and discriminative validities of The Scoliosis Research Society-22 (SRS-22) Patient Questionnaire translated into Japanese as compared with the other language versions. ⋯ The Japanese SRS-22 is valid and may be useful for clinical evaluation of Japanese scoliosis patients, though the self-image subscale may need further assessment.

Comparative Study
Posterior spinal fusion for scoliosis in duchenne muscular dystrophy diminishes the rate of respiratory decline.
To assess the rate of decline in pulmonary function in Duchenne muscular dystrophy (DMD) before and after posterior spinal fusion for scoliosis. ⋯ Posterior spinal fusion for scoliosis in DMD is associated with a significant decrease in the rate of respiratory decline postsurgery compared with presurgery rates.

An experimental animal study. ⋯ Anti-TNF-alpha antibody reduced allodynia only when it was administered soon after the onset of allodynia. Late administration of anti-TNF-alpha antibody did not have an antiallodynic effect.

The association between lumbar facet joint inflammation and radiculopathy was investigated using behavioral, histologic, and immunohistochemical testing in rats. ⋯ When inflammation was induced in a facet joint, inflammatory reactions spread to nerve roots, and leg symptoms were induced by chemical factors. These results support the possibility that facet joint inflammation induces radiculopathy.
