Abstract

Significant hazards to the use of femoral head prostheses–infection, corrosion, fatigue failure, interface motion, latent failure–dictate new standards for new prosthesis models. This study investigates ceramic‐coated metal hip prostheses which have the theoretical advantage of tissue ingrowth. In long‐term analysis, ingrowth did not occur in this study in the pygmy goat. Sintered metal prosteses were inserted in two dogs with bilateral congenital hip dysplasia. Excellent clinical results were obtained with radiologic evidence of bone envelopment of the sintered metal. Based on previous applications of silicone rubber to weight bearing by the author, the advantages of a silicone rubber prosthesis or silicone rubber‐covered prosthesis are tissue compatibility, new bone formation, peak stress dispersal, and simulation of normal articular cartilage. A silicone rubber prosthesis was fabricated for the pygmy goat. It was inserted and initially has given good clinical results.
