PROBLEM TO BE SOLVED: To provide an acetabular hip implant including acetabular shell component that has a first feature and a first insert, the first insert having a second feature that cooperates with the first feature of the acetabular shell component and further includes a third feature.SOLUTION: The implant further includes a second insert having a fourth feature that cooperates with the third feature of the first insert and further includes a fifth feature. A femoral head component includes a sixth feature that cooperates with the fifth feature. Interaction between the first and second features, between the third and fourth features, and between the fifth and sixth features mechanically constrains the acetabular hip implant to prevent dislocation of the femoral head during rotation. |
