Estudo clínico-cirúrgico e morfométrico da regeneração óssea em xenoimplante bovino e aloimplante em tíbia de cães tratados e não tratados com nimesulide

Abstract

The headquartered fractures in the appendixes of the small animals represent great portion of the service in surgical clinics. The purpose of this work was evaluate the bone regeneration with the use of allografts or bovine fetus xenografts, conserved in solution of cefalotina sodic neutral to 0,5%. Twenty adult mongrel dogs were used. We done ostectomia of a fragment of the tibia of the receptor dogs with dimensions same to 10mm x 4mm where then in its place, it was put the allograft or xenograft, in agreement with the group to which belonged the animal. Clinically, support of the limb was observed in the subsequent day to the surgery and general state of the animal. The radiographic evaluation was accomplished before the surgical procedure and in the postoperative immediate, on the 15, 30, 45 and 60 days of evolution. In 15 days beginning of formation of bone callus was observed in the allograft group, already in the xenograft group this was observed to the 30 days in almost all the animals. There were no evidence infection, of deformity or any other alteration in the operated timb, and we concluded that the allograft is incorporated faster than the xenograft, however not being discarded the use possibility of this use.
