Abstract

An acetabular prosthesis and method for its use in an orthopedic surgery is disclosed. The acetabular prosthesis forms a metal bearing, which articulates with a femoral head. The acetabular prosthesis is also configured so as to accept a polymer constraining ring. Should a revision surgery be necessary, the acetabular prosthesis may accept a polymer bearing liner over the metal bearing. The polymer bearing liner then articulates with the femoral head.
