RESUMEN
This article describes a modification of the double-osteotomy radial technique that has been described previously and summarizes our clinical experience with this method in 4 female patients. All patients had improvement in functional motion and were satisfied with the improved appearance of their wrist after surgery.

OBJECTIVE: The aim of this study is to compare the effects of traditional nonsteroidal anti-inflammatory drugs with nonsteroidal anti-inflammatory drugs that are selective cyclooxygenase-2 (COX-2) inhibitors in the process of bone regeneration in a rat model. MATERIALS AND METHODS: Forty-four Wistar strain rats were subjected to osteotomy of the right femur and randomly divided into 3 groups according to the drug to be given (diclofenac, rofecoxib, or placebo). Each group was divided into 2 subgroups according to the time to euthanasia after the surgery. The animals of Subgroup 1 were submitted to euthanasia 2 weeks after surgery, and those of Subgroup 2, underwent euthanasia 4 weeks after surgery. Radiographic examinations and bone callus histomorphometry were analyzed. RESULTS: No intergroup statistical difference was found in the bone callus area or in bone formation area 2 and 4 weeks after surgery. Intra-group analysis concerning the bone neoformation area inside the callus showed a significant difference within the diclofenac group, which presented less tissue. CONCLUSIONS: Fracture consolidation in Wistar rats occurs within less than 2 weeks, and the use of nonsteroidal anti-inflammatory drugs does not significantly influence this process.

Os autores analisam casuística de 11 pacientes vítimas de amputaçöes ao nível do polegar provocadas por mecanismo de avulsäo. Relatam as técnicas das reconstruçöes realizadas e referem os resultados obtidos, imediatamente e tardios. A maioria das amputaçöes ocorreu ao nível da articulaçäo metacarpofalangiana. O índice de sucesso em termos de sobrevida e resultado funcional satisfatório foi de 64 por cento. Concluem que, mesmo nestas situaçöes de alta complexidade, os reimplantes do polegar sempre devem ser realizados
