Abstract

An acetabular shell has a dome hole at the apex that is occluded at the proximal end thereof by a flexible diaphragm affixed to the shell wall of the acetabular shell. The flexible diaphragm moves between a first position spaced from an open proximal end of the dome hole to a second position engaging the open proximal end of the dome hole. Movement of the diaphragm is effected by seating the acetabular shell against the prepared bone of the acetabulum. The position of the diaphragm can be discerned through an open distal end of the dome hole either visually, or tacitly using a suitable feeler probe. The dome hole remains occluded against passage of debris therethrough regardless of the position of the flexible diaphragm.
