Abstract
An improved acetabular cup prosthesis has a cup body with correspondingly shaped outer convex and inner concave surfaces. The cup body has an apex and a base that defines a plane. The cup body outer convex surface has first and second curved, shaped portions positioned in between the base and the apex. In one embodiment, the outer convex surface has specially shaped portion in between the rim and a distance about one third of the distance of the rim to the apex. This specially shaded portion forms an interference fit with a patient's acetabular socket.
