title: Removal of the acetabular component minimizing destruction of the bone bed.
abstract: Removal of a well-fixed acetabular component can be difficult and may produce destruction of the acetabular bone bed. The authors describe a technique for removal of such a component with minimal bone destruction that involves the use of an offset punch and breaking the fixation interface in tension. This technique obviates the need for prying at the interface and fracturing the bone bed.
