Variable position acetabular cup |
摘要 |
A variable position acetabular cup assembly for replacing a natural hip socket includes a symmetrical base cup, a symmetrical polymer bearing, and a nonsymmetrical adapter ring situated between the base cup and the bearing. The base cup is designed to be affixed to the acetabulum to replace the natural socket. The bearing provides a bearing surface for receiving a femur ball. The adapter ring can be mounted on the base cup in a plurality of positions to change the position of the symmetrical bearing after the base cup is secured to the acetabulum.
