Femoral neuropathy caused by reinforcement ring malposition and extruded bone–cement after revision total hip arthroplasty

Femoral neuropathy occurred after revision total hip arthroplasty as a result of pressure from the reinforcement ring and extruded bone–cement (polymethyl methacrylate). Four weeks after the revision surgery, we performed an operation to decompress the femoral nerve and allow neurolysis. Neuropathy improved gradually after the subsequent surgery.
