The pharmacological effects of the methylprednisolone in the treatment of the spinal cord lesion, have been researched. An experimental study was performed with twelve wistar rats subjected to a contusion lesion of the spinal cord, by the NYU system. The rats were divided in two groups; the MP group which received the methylprednisolone after the contusion lesion and the control group, which received a 0,9% physiological serum. An analysis of the recuperation of the functional movement of the rats was accomplished on the 2nd, 7th and 14th day after the contusion, utilizing the BBB test. On the fourteenth day the rats were sacrificed and the histological findings of the spinal cord lesion were analyzed. It was noted that the rats from the MP group exhibited an improvement in the recuperation of their functional movement compared to that of the control group, and the histological findings of the spinal cord lesion couldn't be correlated with the recuperation of their functional movement.
Objectiveto assess the surgical technique using the modified palm open technique for the treatment of severe contractions of Dupuytren's disease.Methodsover a period of four years, 16 patients underwent surgical treatment, and in its entirety belonged to stages III and IV of the classification proposed by Tubiana et al. We performed measurements of the extension deficit of the metacarpophalangeal joints, proximal and distal interphalangeal in preoperative, postoperative (3 months) and late postoperative period (5–8 years). Angles greater than 30° metacarpophalangeal joints and 15° proximal interphalangeal the results were considered surgical recurrence.Resultsthere was obtained an average of 6.3° at the metacarpophalangeal joint, 13.8° in the proximal interphalangeal and distal interphalangeal at 1.9°.Conclusionthe modified open palm technique is an effective method in the surgical treatment of severe contractures in Dupuytren's disease.
RESUMOEste estudo apresenta e discute os resultados da análi-se biomecânica, radiográfica e anatômica de 20 peças de coluna cervical de cadáveres humanos, submetidas à corpectomia de C 5 , discectomia adjacente e estabilização com enxerto de fíbula. Os ensaios em flexão foram realizados em Máquina Universal de Testes. Nenhuma fratura ou extrusão do enxerto foi observada. A falha mecânica ocorreu na interface corpo vertebral-enxerto fibular, caracterizada por fratura dos corpos vertebrais adjacentes em 11 experimentos e afundamento da esponjosa em nove. O ligamento longitudinal posterior e o complexo ligamentar posterior não foram lesados em nenhuma das peças. Concluem que, em estudo experimental, o enxerto de fíbula é resistente e proporciona estabilidade imediata à coluna cervical quando submetido a carga em flexão.Descritores: Biomecânica; coluna cervical; enxerto fibular.
INTRODUÇÃOOs traumas em flexão são os tipos mais comuns de traumas cervicais (1) . Estas lesões podem resultar em fratura do corpo vertebral, associadas ou não a instabilidade ligamentar, tornando a estabilização vertebral difícil de manter ou alcançar com métodos conservadores. Além disso, os traumas em flexão podem resultar em compressão medular secundária a fratura do corpo ou herniação discal.
