To compare the expression of cytokines and core protein of proteoglycan in the scoliotic concave and convex cartilaginous endplate using immunohistochemical staining. ⋯ There was a significantly higher expression of TGFbeta1 and bFGF, although a lower expression of the core protein on the concave side, which suggests a possible etiological factor or a secondary change in the development of adolescent idiopathic scoliosis.

Retrospective clinical study from 2 centers. ⋯ Using posterior surgery only, we have been able to at least equal the results reported in the literature by investigators using combined approaches. Isolated posterior instrumentation and arthrodesis achieve satisfactory cosmetic, radiographic, and patient-based outcomes in adolescents with idiopathic scoliosis with thoracic curves 70 degrees-90 degrees, without the added expense and morbidity of anterior release.

A retrospective study was performed to identify horizontal fractures of the body of the axis, with special attention to their pattern, prevalence, and clinical outcome. ⋯ Horizontal fractures of the Chance-type of the body of the axis are rare. Conservative treatment proved to be effective.

Case report. ⋯ It is important to maintain an awareness for the possible association between HIV lipodystrophy and symptomatic epidural lipomatosis.

The authors provide their results in performing multilevel oblique corpectomy for degenerative spondylotic myelopathy in 48 patients. ⋯ Multilevel oblique corpectomy was found to be a safe technique that guarantees good results in terms of both regression of clinical symptoms and long-term spinal stability.
