Claim 0:
1. A method for stabilizing first and second bones in a patient, comprising: inserting an implant between the first and second bones, the implant including:
a first endplate having a first side adapted to be affixed to the first bone of the patient, and a second side opposite the first side, the second side having a first part of a snap fit mechanism, the first endplate having a plurality of projections adapted to be affixed to the first bone;
a resilient core having a third side and a second part of the snap fit mechanism such that the resilient core mates with the first endplate through the snap fit mechanism, the resilient core further including a fourth side opposite the third side, the fourth side having a convex surface having a first radius;
a second endplate having a fifth side engageable with the fourth side, and a sixth side opposite the fifth side adapted to be affixed to the second bone of the patient, the second endplate having a plurality of projections adapted to be affixed to the second bone, the fifth side having a recessed concave surface having a second radius larger than the first radius so as to provide a sliding motion relative to each other;
whereby a vertical axis of the implant is defined as extending from the first bone to the second bone;
whereby the core is positionable between the first and second endplates;
wherein the core separates the first and second endplates at a relative first distance along the vertical axis, the core being resiliently deformable under pressure to separate the first and second endplates at a second, lesser relative distance along the vertical axis;
wherein a plurality of pins extend from the second side of the first endplate substantially transverse to the vertical axis of the implant into the resilient core; and
wherein when said first endplate is affixed to the first bone, and said second endplate is affixed to the second bone, and said core is positioned between said first and second endplates, the first and second bones are stabilized, and said core may both resiliently deform and slide separately or simultaneously, to enable six degrees of kinematic motion of the two bones similar to a natural kinematic movement of the bones.
