ABSTRACT:
An acetabular cup system is provided in which an insert or liner may be selected from a plurality of types of inserts to be used with an acetabular shell. One insert may be oriented after it is removably inserted into the acetabular shell. After an orientation is selected, it may be permanently fixed by pins. The other insert includes a snap-in ring that allows the insert to be snapped into position with the shell after its orientation is selected. The snap-in insert and ring are removable from the shell using a device for removing such snap-in insert and ring.
