Abstract
An acetabular cup prosthesis designed to customize the fit and stability of an acetabular cup in deficient acetabulae without excessive reaming of good bone surrounding the deficiency. The acetabular cup prosthesis generally comprises a cup-shaped body portion, an extension, and a liner. The extension is preferably produced at selected angles, which are appropriate to various acetabular defects, and is designed to connect to the cup-shaped body portion. The body portion and extension are secured to the bone and the liner is inserted within the body portion. Those surfaces of the body portion and extension contacting the surface of the bone are preferably porous surfaces that may have also been coated with a coating to enhance bone growth.
