Abstract
The failure of uncemented acetabular components has been described in association with component wear, disassembly, and proximal migration. The authors report a case of medial displacement following minor trauma some 18 months after surgery. The component involved differs in design from both press-fit, porous-coated or screw-in, fully threaded acetabular cups. The authors suggest that additional screws should be inserted to enhance long-term stability.
