1. A spinal prosthetic implant system for implantation between an upper and lower vertebra, comprising:
a first spinal prosthetic implant, the first spinal prosthetic implant comprising a first upper joint component and a first lower joint component, the first upper joint component comprising an upwardly facing bone engagement surface and a cortical wall engaging portion, a concave shaped first upper articulation surface and a first upper bumper, the first upper, the first lower joint component comprising a convex shaped first lower articulation surface and a first lower bumper, the first upper and lower bumpers positioned between the first upper and lower joint components, the first lower bumper spaced apart from the first lower articulation surface, the first upper articulation surface of the first upper joint component engaging with the first lower articulation surface of the first lower joint component to create a first ball-and-socket joint that permits the first upper joint component to articulate relative to the first lower joint component; and
a second spinal prosthetic implant, the second spinal prosthetic implant comprising a second upper joint component and a second lower joint component, the second upper joint component comprising a second upper articulation surface, the second upper articulation surface includes a concave shape, the second lower joint component comprising a second lower articulation surface, the second lower articulation surface includes a convex shape, the second upper articulation surface of the second upper joint component engages with the second lower articulation surface of the second lower joint component to create a second ball-and-socket joint that permits the second upper joint component to rotate and articulate relative to the second lower joint component;
the first spinal implant adapted for placement in a first orientation between the upper and lower vertebra and the second spinal implant adapted for placement in a second orientation between the upper and lower vertebra.
