Abstract: A tool for implanting an augment into a cavity in bone can include a proximal portion and a distal portion. The proximal portion can include a handle. The distal portion can include an adjustment member and an augment interface portion. A shaft can be interconnected between the proximal and distal portions. An engagement portion can be configured at the augment interface portion and coupled to the adjustment member. Movement of the adjustment member can urge the engagement portion in a direction outboard relative to the shaft. A related method can include securing an augment to the tool by locating an augment interface portion of the tool at an engagement site defined on the augment. The adjustment member can be moved on the tool in a first direction, thereby urging an engagement portion of the tool into secured engagement with the engagement site of the augment.

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.
