Total hip arthroplasty in dogs: Experimental study using a prosthesis made in Brazil

Total hip prosthesis is one of the most accepted methods used in the United States and Europe for the treatment of severe hip dysplasia in dogs. However, there are few studies with the technique and the procedure is still not well established in Brazil. A prosthesis made in Brazil was used. The purpose of this study was to evaluate its application and determine the postoperative finds and complications. Ten mature healthy dogs were used. A fixed-head cemented total hip prosthesis was applied on the left leg of the dogs. A chrome-cobalt femoral stem and high density polyetylene acetabular cup was used. Clinical and radiographic evaluations were performed before surgery and again at 30, 60, 90, 120 e 150 days post operation. Proper weight bearing was noticed on the operated limb in the majority of the dogs. The main complications were the dislocation and loosening of the acetabular cup.
