title: Recementing a femoral component into a stable cement mantle using ultrasonic tools.
abstract: Recementing a femoral prosthesis into a retained cement mantle was done during revision total hip arthroplasty in 15 patients using ultrasonic tools to reshape the existing cement mantle. Early complications such as bone perforation or fracture were avoided. The 2-year followup in 4 patients revealed no adverse effect on the bone-cement interface as judged radiographically. One patient had rerevision for instability at 1 year after operation. Indications for this technique include isolated failure of the cement-prosthesis interface, femoral component fracture, or isolated acetabular revision in which exposure needs, instability, leg length inequality, or femoral-head size dictated change of the femoral component.
