Abstract
An acetabular shell can receive bone screws through a screw hole that is initially occluded by a plug in sintered connection with the wall of the screw hole. The sintered connection can be broken to permit removal of the plug, if desired. The plug prevents migration of wear debris from the interior of the shell to the exterior of the shell through an unused screw hole.
