Abstract
An acetabular cup has a shell component with an outer surface including a frusto-conical surface portion and a spherical surface portion and an acetabulum is prepared with an inner surface including a frusto-conical surface portion and a spherical surface portion, the spherical surface portions having essentially the same radius and the frusto-conical surface portions having relative dimensions such that upon nesting of the spherical surface portions in contiguous relationship, the frusto-conical portions engage one another in an interference fit to secure the shell component within the prepared acetabulum.
