Abstract

A prosthetic system for implantation between upper and lower vertebrae having an upper joint component and a lower joint component. The joint is adapted for implantation within a disc space between the upper and lower vertebrae, allowing the upper and lower vertebrae to move relative to one another. The system further includes a bridge component extending posteriorly from the lower joint component and from the disc space, with the bridge component having a lower contact surface configured for engaging a resected bone surface of a pedicle of the lower vertebrae. The distal end of the bridge component comprises a connection component adapted to receive a fastener.
