ABSTRACT:
An exemplary acetabular cup prosthesis insertion and removal assembly includes a bayonet coupler that has fingers for extending into recesses of an acetabular cup to hold the cup onto the coupler. A holder-driver member is secured to the bayonet coupler, and has an enlarged head for receiving impacts. A securing member for engaging the inner surface of the acetabular cup is adjustably mounted to the holder-driver member to apply a biasing force to urge the cup away from the holder-driver member and the bayonet coupler, thereby firmly holding the cup onto the coupler. An alignment guide assembly with at least one guiding arm or member may be mounted on the holder-driver member to facilitate accurate placement of the acetabular cup. A slap-hammer or extractor is also provided and may be attached to the holder-driver member to remove an acetabular cup that is initially misplaced in the acetabulum.
