Abstract:
1. An acetabular prosthetic comprising: a first prosthetic having a bone engagement surface, a first inner integral generally spherical polished concave bearing surface configured to directly engage an articulating surface of a femoral component, a locking mechanism; and a second prosthetic having a second spherical concave bearing surface, said second prosthetic being configured to be disposed between the generally spherical polished concave bearing surface and an articulating surface of a femoral component, wherein said locking mechanism is configured to fixably couple the second prosthetic to the generally spherical polished concave bearing surface so as to prevent relative movement therebetween, wherein the acetabular prosthetic is configured such that the generally spherical polished concave bearing surface engages the articulating surface of the femoral component in a first configuration or the second spherical concave bearing surface engages the articulating surface of the femoral component in a second configuration, in the second configuration said second prosthetic is selectively engaged with said first prosthetic to allow direct engagement of the articulating surface of the femoral component with the second spherical concave bearing surface.
