An acetabular prosthesis has an oblong geometry in which its dimensions in a first axis exceed those in a second axis that is normal to the first axis. The prosthesis has a superior, bone engaging surface with primary and secondary partial spheres that are merged together. The opposed inferior surface of the prosthesis includes at least one hemispherical cavity that is formed within the primary partial sphere. The primary partial sphere has dimensions that exceed the secondary partial sphere by less than or equal to about 5%.
