Abstract
An acetabular cup assembly for use with liners is described. The acetabular cup assembly includes a cup and a liner. The cup has an outer surface, a generally concave inner surface and a top face. The inner surface includes a cylindrical band having a plurality of inward-facing recessed scallops, a tapered wall adjacent to the band, and an inner spherical surface adjacent the tapered wall. The inner spherical surface has a substantially uniform radius of curvature. A single groove interrupts the spherical surface. The liner has a substantially convex outer surface and includes a rim and a plurality of outward-projecting scallops adjacent the rim. The scallops of the liner are configured to engage the scallops of the cup when the liner is seated in the cup. Related methods of use are also provided.
