title: Wear of a titanium-alloy shoulder prosthetic head.
abstract: We present a case report of extensive wear that occurred on the surface of the titanium-alloy head of a shoulder prosthesis after only 2 years' service. Such wear warrants discontinuing the use of titanium-alloy articulating surfaces even in nonweight-bearing joints.
