Abstract
Foi realizado um estudo experimental sobre o desenvolvimento e desempenho de um fixador externo flexível no processo de consolidação de tíbias de carneiros submetidas à osteotomia transversa mediodiafisária. Foram empregados no estudo 20 carneiros da raça Santa Inês, com massa corporal média de 37kg, divididos em diferentes grupos conforme o período de observação pós-operatória, de 30, 45, 60 e 90 dias. Ao final, os animais sofreram a eutanásia e as tíbias foram removidas para estudo de volumetria transversal do calo ósseo por tomografia computadorizada e ensaio mecânico destrutivo. Os resultados mostraram que ocorreu a formação de calo ósseo volumoso, caracterizando assim a ocorrência de deslocamento de carga axial para o foco da osteotomia, promovida pelo fixador externo utilizado. No ensaio mecânico, observou-se que as comparações entre os grupos respectivos intactos e operados foram significantemente diferentes (P<0,05), com exceção do grupo com 90 dias, demonstrando haver rigidez equivalente ao osso normal. Em nenhum dos animais, houve desenvolvimento de pseudoartroses ou não união óssea. Diante dos resultados, conclui-se que o uso do fixador com haste flexível abordado nesta pesquisa para o tratamento de fraturas dos ossos longos de animais de médio porte foi de fácil aplicação, reprodutível e recomendável.
An experimental study was carried out to verify the development and performance of a flexible external fixator on the bone healing process of the tibia of sheep submitted to a transverse diaphyseal osteotomy. It was used twenty Santa Inês sheep with average weigh of 37kg divided in groups, according to the period of postoperative observation of 30, 45, 60 and 90 days. At the end, the animals were sacrificed and the tibiae were removed for study of transverse callus volumetric by computed tomography and destructive mechanical testing. The results had shown that the formation of voluminous callus occurred, thus characterizing the occurrence of displacement of axial load to the focus of the osteotomy, promoted by the used external fixator used. The mechanical testing showed that the comparisons between the respective intact and operated groups were significantly different (P<0.05) except for the group with 90 days, which demonstrated equivalent stiffness when compared to normal bone. In none of the animals there was development of pseudarthrosis or non-union of the bone. Given the results, it was conclude that the use of the flexible fixator covered in this research for treatment of long bones fractures in medium animals was easy to apply, reproducible and recommended.
