Silicone arthroplasty for hallux rigidus. Implant wear and osteolysis.

Between 1980 and 1985, silicone hemiprostheses were implanted because of hallux rigidus in 58 feet of 43 patients who were followed up after an average of 5 years. The majority were satisfied and had good function without pain. However, the toes had shortened because of implant wear, and there was considerable associated osteolysis.
