Abstract

Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup, a pre-assembled liner and flange construct, and a dual mobility bearing (e.g., a dual articulating femoral head component and insert). In one embodiment, the pre-assembled liner and flange construct may be coupled together by a band coupled to the flanges, the band being arranged and configured to be pressed onto an outer surface of a liner. The pre-assembled liner and flange construct being arranged and configured to accept the dual mobility bearing so that it is freely rotatable relative thereto during use.
