A method for removing the polyethylene liner during revision total hip arthroplasty.
Extraction of the polyethylene liner is necessary if acetabular fixation screws and the metal acetabular shell are to be revised during total hip arthroplasty. In some situations, revision of the polyethylene liner alone may be indicated for excessive wear and osteolysis. A simple method for dissociating the liner from the shell is described in this report. No special instruments are needed with this technique.
