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.

A method and apparatus for repairing a cavity in bone may can include a longitudinal shaft having a distal end and a proximal end. A cutting tool can be selectively attachable to the distal end. A one-piece guide can have a body defining an opening and including a locator member extending therefrom. The locator member can be engageable to a first portion of the bone providing a reference point relative to the cutting tool while the cutting tool engages a second portion of the bone during cutting. The body can be slidably advanced onto the longitudinal shaft through the opening from the proximal end to an operating location in an assembled position. During operation, the body can define a handle concentric with the longitudinal shaft.
