    Polyethylene wear and subsequent osteolysis have been recognized as problems in association with fixed acetabular components. Bipolar implants are also susceptible to failure of the bearing surface and its sequelae. The polyethylene wear associated with a bipolar implant is difficult to measure radiographically because of the design of the implant. The purpose of the current report is to demonstrate that polyethylene wear and subsequent osteolysis also occur with this type of implant. We report the cases of five patients who had failure of the polyethylene after a bipolar hemiarthroplasty of the hip. Four of the five patients had marked osteolysis.
