Abstract: The present invention provides a prosthetic implant for partial replacement of an anatomical part. The implant includes a unitary body with a generally flat lower end face for supporting the body on a cortical surface, a generally curved exterior side face and a generally flat upper end face. A modular bearing plate disposed on the upper end face includes an upper articular surface for supporting articulation of an anatomical surface and an opposed mounting surface in contact with the upper end face. A fixation bracket includes a first end coupled to the exterior side face of the body and a second end projecting downward past the lower end face of the body with a contour generally corresponding to an outer surface of an anatomical part. The prosthetic implant is configured to replace a portion of the outer surface of the anatomical part and extend partially into the anatomical part.
