title: Use of castor oil polyurethane in an alternative technique for medial patella surgical correction in dogs.
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
  Twelve adult dogs, of both sexes, were randomly allocated to two different groups of six 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 II (control) which consisted of the conventional trocleoplastia technique with wedged cut of the left femoral troclea. The dogs were sacrificed after 30 or 90 days and the anathomic peaces were analyzed macro and microscopically. Chi square and Wilcoxon 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.
  
  
  CONCLUSIONS
  Castor oil polymer assisted cicatrisation process, was biocompatible without inflammation, and it can be used in joints as an alternative for bony filling.
