Abstract
A case of femoral component loosening secondary to impingement on an extended-lip acetabular cup liner is presented. This impingement led to the accelerated creation of particulate polyethylene wear debris. The particulate polyethylene induced an osteolytic response about the femoral component, which contributed to the failure of this component. It is recommended that intraoperative examination for impingement, especially in extension, be performed when using liners of this design.
