Early experience with the Autophor prosthesis using a posterior approach.

Twenty-eight Autophor hip prostheses have been implanted in 25 patients, using primarily a posterior approach. Complications have included two dislocations and two femoral shaft fractures. One dislocation required reoperation. The shaft fractures healed in three months with bone grafting and cerclage wiring. There were no infections and no cases of loosening or component failure. Radiological follow-up including bone scan suggests implant boney stabilization at six months. Our early experience suggests that this implant is quite successful, especially in the young patient and the patient with significant loss of bone stock from protrusio or revision surgery.
