Abstract
An orthopedic prosthetic implant having a pyrolytic carbon or ceramic articulating surface and a metallic sheath or shell interfacing with adjacent bone. The articulating surface and shell are attached to one another with a layer of resilient adhesive, such as polymethylmethacrylate (PMMA) which forms a shock absorbing layer between the pyrolytic carbon or ceramic parts and the metal parts. Also, a circumferential seal enclosing two adjacent articulating surfaces on adjacent implant parts. The invention further includes first and second implant parts having mating articulating surfaces, the first and second implant parts being joined by ligament structures. Ligament structures include bands or spring means connecting the first and second implant parts.
