Utilizacao da poliuretana de mamona em técnica alternativa de correção cirurgica da luxaçao medial de patela em caes: análise morfo-funcional

Abstract

Objective: Comparative morphologic study of utilization of castor oil polymer in dogs joints, as an alternative technique to autogenous graft, in surgical correction of medial patella luxation. Methods: Sixteen adult dogs, of both sexes, were randomly allocated to two different groups of eight animals each. Group I (biopolymer) consisted of the deepening of the right femoral troclea, with the implantation of the biopolymer prothesis, and compared to group (control) which consisted of the conventional trocleoplastia technique with wedged cut of the left femoral troclea. The dogs were sacrified after 30 or 90 days and the anathomic peaces were analyzed macro and microscopically. Fisher and Mann-Whitney tests were used for the statistic analyses of the results, considering probability of 5%. Results: It was not observed bony integration on the castor oil polymer group. There was resorption of the graft along experimental period and absence of inflammatory cells in the studied periods. Conclusion: Castor oil polymer assisted cicatrisation process, was biocompatible without inflammation, and it can be used in joints as an alternative for bony filling.
