Claim 9:
10. A prosthetic system for implantation between upper and lower vertebrae, the prosthetic system comprising:
an upper joint component comprising an upper material, an upper anterior motion limiter, an upper posterior motion limiter, an upper bone contacting surface for engaging a resected lower surface of the upper vertebrae and a concave upper articulation surface, the concave upper articulation surface positioned between the upper anterior motion limiter and the upper posterior motion limiter;
a lower joint component comprising a lower material, a lower anterior motion limiter, a lower posterior motion limiter, a first lower bone contacting surface for engaging a resected upper surface of the lower vertebrae and a convex lower articulation surface, the convex lower articulation surface positioned between the lower anterior motion limiter and the lower posterior motion limiter, the convex lower articulation surface engages with the concave upper articulation surface to allow rotationally unconstrained motion of the upper joint component relative to the lower joint component; and
a bridge component extending posteriorly from the lower joint component, the bridge component having a second lower bone contacting surface configured for engaging a resected bone surface of a pedicle of the lower vertebrae, wherein the distal end of the bridge component comprises a connection component adapted to receive a fastener.
