More Information
Summary:An orthopaedic components, prostheses, and methods for a hip arthroplasty are disclosed. An acetabular prosthetic component (22) includes an outer rim (82) and a cavity (16) defined by an inner wall (112). The cavity is sized to receive a femoral head (14) of a femoral prosthetic component. The inner wall includes a curved surface (114) extending inwardly from the outer rim to an inner end (116), and a semi-spherical surface (118) connected to the inner end of the curved surface. The inner wall is shaped to resist dislocation of the femoral head component from the cavity and permit the femoral head component to articulate over a range of motion.
