title: Dissociation of a polyethylene liner from an acetabular cup.
abstract: A polyethylene linear dissociated from a metal acetabular shell that could not be removed at the time of hip revision because the hexagonal hole in its screw head had become rounded off. A high-speed metal cutting burr was used to remove the screw and allow cup revision.
