ABSTRACT:
A prosthetic part for use as an orthopedic implant has a base member defining an outer surface for implantation adjacent a prepared bone surface. The outer surface includes a recessed area having a predetermined shape and depth. A first rigid plate having this predetermined shape and having a plurality of elongated slots formed therein is fixedly attached within the recesssed area of the base member. A second rigid plate also having the same predetermined shape as the recess and also having a plurality of elongated slots formed therein is attached to the first rigid plate. The elongated slots of the second plate are angularly offset with respect to the elongated slots in the first plate to produce a controlled porosity. The thicknesses of the first and second plates are predetermined so that the outer surface of the second plate is continuous with the non-recessed outer surface of the base member.
