An implantable prosthetic element (10) includes a first end plate (12) and a second end plate (14), each of which has a bone-facing surface (42,46) and an opposed mating surface (44,48). The bone-facing surfaces of the first end plate (42) and the second end plate (46) each have at least one lobe (22,23,24,25) protruding therefrom. Some or all of the lobes (22,23,24,25) may have a plurality of wedge-like fins (18) which protrude therefrom. An elastomeric core (16) is interposed between, and attached to, the mating surfaces (44,48) of the first end plate (12) and the second end plate (14). <IMAGE> |
