An acetabular cup component can include a hemispherical first shell, an annular ring, and a second shell. The annular ring can laterally extend from and circumscribe an outer surface of the first shell and can include a first portion for engaging an anatomy. The second shell can include a second portion for engaging the anatomy adjoining the first portion. Another acetabular cup component can include a first shell, a second shell, and a support ring. The support ring can be coupled to an end portion of the first shell and can include a portion for engaging an anatomy and a rim for engaging a bearing. Another acetabular cup component can include a hemispherical inner shell composed of Cobalt, a hemispherical intermediate shell coupled to an outer surface of the inner shell by a diffusion bond, and a hemispherical outer shell coupled to an outer surface of the intermediate shell. |
