Abstract
An acetabular prosthesis assembly includes an acetabular shell component and an acetabular bearing component. The shell component includes a concave inner wall having a tapered surface with multiple anti-rotation slots defined therein. The bearing component includes a convex outer wall as well as an annular flange and multiple anti-rotation keys extending radially outward from the outer wall. When the anti-rotation keys are positioned in rotational alignment with the anti-rotation slots, the flange of the bearing component is positioned in contact with the tapered surface of the shell component. When the anti-rotation keys are positioned out of rotational alignment with the anti-rotation slots, the flange is spaced apart from the tapered surface. Methods for assembling and using the acetabular prosthesis assembly are also disclosed.
