Abstract
Devices, apparatus, and systems for replacing at least some of the functionality of the natural hip joint and associated methods of implantation are disclosed. In one aspect a prosthetic acetabular cup system is provided. The system includes a metal shell comprising an outer surface for securely engaging a prepared portion of an acetabulum and an opposing inner surface. In some instances, portions of the inner and outer surfaces define an anchoring section that is deformable between an insertion configuration—where the anchoring section projects inwardly from the inner surface—and an anchoring configuration—where the anchoring section projects outwardly from the outer surface to define an anchoring protrusion for engaging the prepared portion of the acetabulum. In some embodiments, the system also includes a pliable articulating component having an outer surface including at least one engagement feature sized and shaped to engage with the metal shell. The pliable articulating component includes an inner surface for articulatingly receiving a femoral head.
