ABSTRACT:
The hip joint acetabulum uses a synthetic ring for snap-fitting the acetabulum body within the outer bowl. The ring is slit to provide for the snap fit connection and is provided with an annular lug which projects into an annular groove within the outer bowl. Recesses are also provided to permit a tool to penetrate into the acetabulum to separate the lug from the remainder of the ring to permit ready detachment of the body from the bowl.
