title: Failure of the polyethylene liner leading to notching of the femoral component in bipolar prostheses.
abstract: Polyethylene wear is an increasingly recognized problem in joint replacement surgery. Three cases of polyethylene wear in bipolar hip prostheses are presented. Owing to failure of the polyethylene liner, impingement of the metal shell produced notching of the femoral component.
