Abstract
An implant comprises a plastic body and a metallic, porous surface securely fixed to the body. The implant is made by first producing a porous mold insert having a porous metal structure and a soluble filler material filling a portion of its pores. The mold insert is then placed in a mold and plastic is injected into the mold and the exposed pores of the insert to form the implant body and securely attach the body and insert. The implant is then contacted by a solvent which dissolves the filler material to expose that portion of the insert which had been filled.
