ABSTRACT:
A prosthesis for a deficient acetabulum of a patient having a cup portion and a flange member. The flange member has a base portion that extends upward along a portion of the upper rim. A generally planar screw retaining portion extends from the base portion, and is inclined from the base portion such that at least a lateral portion of a lower surface of the screw retaining portion is positioned below the upper rim while an upper surface of the screw retaining portion is positioned above the upper rim. The screw retaining portion has a first threaded hole, a second threaded hole and a neutral threaded hole, with the neutral hole positioned between the first and the second holes. The holes are inclined at certain orientations to allow for fixation with screws in a deficient acetabulum, and for use in a left or right hip.
