Sciatic nerve palsy after cementless total hip arthroplasty. Treatment by modular neck and calcar shortening: a case report.

This is a case report of sciatic nerve palsy after total hip arthroplasty. Although the patient's symptoms became worse postoperatively, full recovery occurred after shortening of the calcar and femoral neck length. For acute sciatic nerve palsy patients with worsening of symptoms in the postoperative course in spite of hip and knee flexion, reexposure for early recognition of the sciatic nerve condition and reoperation by shortening the femoral neck may be an option.
