ABSTRACT:
A prosthesis includes a trunnion having a first end defining a uniform cross-section and a second end adapted to be fixed to a prosthesis stem. A ceramic head has a first bearing surface on which a second prosthesis fixed to a second bone can articulate. The ceramic head defines a recess. The first end of the trunnion is fixedly received within the recess. The second end of the trunnion is releasably connectable to the prosthesis stem by a taper connection.
