Segmental femoral cement extraction at revision hip arthroplasty - a safe technique.

Conventional methods of femoral cement extraction at revision hip arthroplasty may be associated with incomplete cement removal, excessive sacrifice of cancellous bone stock, inadvertent cortical perforation, or fracture. Segmental femoral cement extraction is a technique, first introduced in the early 1990s to optimise cement removal while minimising the potential complications of this procedure. It involves the instilling of fresh polymethylmethacrylate (PMMA) into the carefully prepared cement mantle after implant removal.
