Abstract: A prosthetic system for implantation between upper and lower vertebrae comprises an upper joint component. The upper joint component comprises an upper contact surface and an upper articulation surface. The system further includes a lower joint component. The lower joint component comprises a lower contact surface and a lower articulation surface configured to movably engage the upper articulation surface to form an articulating joint. The articulating 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 one of either the upper or lower joint components and from the disc space. The bridge component has a distal end opposite the one of the either upper or lower joint components. The distal end of the bridge component comprises a connection component adapted to receive a fastener.
