Periprosthetic fractures of the femur after total hip arthroplasty.

The incidence of periprosthetic femur fracture has increased recently, and these fractures have become of a great concern to the reconstructive orthopaedic surgeon. Intraoperative fractures are usually stable. To prevent intraoperative fracture, careful preoperative planning and gentle surgical techniques are essential. In managing unstable intraoperative and late postoperative periprosthetic fractures, the surgeon should know the exact pattern of fracture, prosthesis stability, and bone quality. Loose prostheses should be revised and displaced fractures should be reduced and adequately fixed.
