  • Reinforced fiber bone replacement implant having treated surfaces and a method for its manufacture
    Patent number: 4714467
    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.
