Abstract
An acetabular prosthesis including a ceramic shell having multiple layers and a polymer liner formed integrally with the shell. The acetabular prosthesis shell is formed of a ceramic wherein several layers with varying porosities and thicknesses are sintered together to form a unitary structure. A polymer inner liner forms a bearing within the shell to receive the ball of a femur or femur prosthesis. The polymer liner is formed in the ceramic shell and includes a plurality of portions which interdigitate into the pores of the inner porous layer of the ceramic shell.
