An implantable prosthetic element includes a first end plate and a second end plate, each of which has a bone-facing surface and an opposed mating surface. The bone-facing surfaces of the first end plate and the second end plate each have at least one lobe protruding therefrom. Some or all of the lobes may have a plurality of wedge-like like fins which protrude therefrom. An elastomeric core is interposed between, and attached to, the mating surfaces of the first end plate and the second end plate.
