A Simple Technique to Remove an Incarcerated Ceramic Liner in Revision Hip Arthroplasty

Extraction of a well-fixed ceramic liner during revision total hip arthroplasty can be technically challenging, particularly when acetabular fixation screws prevent en bloc removal of the shell and insert without causing collateral damage to the adjacent pelvic bone. It is also important to remove the ceramic liner intact, as ceramic debris left in the joint may cause third body wear with premature articular wear of the revised implants. We describe a novel technique to extract an incarcerated ceramic liner when previously described strategies prove ineffective. Knowledge of this technique will help surgeons avoid unnecessary damage to the acetabular bone and optimize prospects for stable implantation of revision components.
