TECHNIQUE AND RESULTS FOR TOTAL HIP-REPLACEMENT IN SHEEP - AN EXPERIMENTAL-MODEL

Fifty healthy adult Suffolk cross sheep were evaluated as a research a nimal for cemented total hip replacement. The surgical technique, peri -operative care, and long-term evaluation of the animals is reported. A modular cemented canine hip replacement system was used in this proj ect. Postoperative fractures of the operated femur were observed in fi ve animals. Two sheep developed septic loosening of the ace-tabular co mponents. Two sheep experienced immediate postoperative luxations. One animal developed an acetabular fracture and infection. Five sheep exh ibited mild lameness of the operated Limb one year postoperatively, wh ile all others had a normal gait. Postoperative activity level played a significant role in the development of femur fractures.
