Claim 0:
1. A prosthetic system for implantation between upper and lower vertebrae, the prosthetic system comprising:
an upper joint component comprising an upper keel, an upper anterior motion limiter, an upper posterior motion limiter, an upper bone contacting surface for engaging a resected surface of the upper vertebrae and a concave upper articulation surface;
a lower joint component comprising a lower keel, a lower anterior motion limiter, a lower posterior motion limiter, a first lower bone contacting surface for engaging a resected surface of the lower vertebrae and a convex lower articulation surface, the convex lower articulation surface engages with the concave upper articulation surface to allow a full range of rotational motion of the upper joint component relative to the lower joint component, the upper joint component capable of moving from a first position relative to the lower joint component, the first position comprising the upper anterior motion limiter contacting at least a portion of the lower anterior motion limiter to allow and limit a flexion motion, to a second position relative to the lower joint component comprising the upper posterior motion limiter contacting at least a portion the lower posterior motion limiter to allow and limit an extension motion, the upper and lower anterior motion limiters positioned anterior to the concave upper and convex lower articulation surfaces; 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.
