Abstract

In a method of producing implants of bone replacement material from resin reinforced with carbon fiber at least the fibers in the parts of the surface which are to come into contact with the bone tissue are exposed by mechanical treatment. This provides for an improved unification of the bone with the implant. The fibers at the surface may be fibers of a fabric which is wrapped around a basic member shaped to conform to the desired implant.
