The canine cemented modular total hip prosthesis.

Total hip replacement (THR) is well established as a treatment modality for dogs with noninfectious, nonneoplastic, disabling conditions of the coxofemoral joint. Since the mid 1970s, a fixed-head prosthesis has been used in this procedure. A modular prosthesis, which is based on many of the technical advances found in human prostheses, now is available for use in veterinary medicine. The prosthesis, surgical instrumentation, surgical technique, and clinical results have been evaluated in a prospective study conducted at The Ohio State University's College of Veterinary Medicine. The modular prosthesis provides results equal to or better than the fixed-head prosthesis.
