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.

An intervertebral disc includes a superior endplate having an upper vertebral contacting surface and a lower bearing surface, wherein the upper vertebral contacting surface of the superior endplate has a central portion that is raised relative to a peripheral portion of the superior endplate, and wherein the lower bearing surface has a concavity disposed opposite the raised central portion. The disc includes an inferior endplate having a lower vertebral contacting surface and an upper surface, wherein the lower vertebral contacting surface of the inferior endplate has a central portion and wherein the upper bearing surface has a concavity disposed opposite the central portion. A core is positioned between the upper and inferior endplates, the core having upper and lower core bearing surfaces configured to mate with the bearing surfaces of the upper and inferior endplates. The upper vertebral contacting surface of the superior end plate has a different shape than the lower vertebral contacting surface of the inferior end plate.

Disclosed are systems, devices, methods and surgical procedures for altering and/or correcting the alignment of adjacent bones, including bones of the spine.

Systems and methods to evaluate a joint implant device are provided. The joint implant device can include a socket that at least partially receives a first joint component. The joint implant device can include a socket housing coupled with the socket. The joint implant device can include a first sensor, a second sensor, and a third sensor each disposed between the socket and the socket housing. The joint implant device can include a socket extension coupled with the socket. The joint implant device can include a socket housing extension coupled with the socket housing. The joint implant device can include a fourth sensor disposed between the socket extension and the socket housing extension. At least three of the first sensor, the second sensor, the third sensor, or the fourth sensor can detect a force between the socket and the first joint component.

The present invention relates to an articular joint replacement system. The system has first and second components. Each component has a tapered head piece for covering the end of a bone and for acting as an articular surface, an integrally formed screw stem having a length sufficient to extend into the medullary canal, and inwardly angled bone grips affixed to the underside of the head piece to allow solid fixation to the bone by compression press fit. The head piece of the first component is provided with a shaped exterior surface which complements the shaped exterior surface of the head piece of the second component and which allows motion in three planes.

The present invention relates to a stabilized ankle prosthesis configured for use in patients with compromised soft tissue in the ankle. The prosthesis of the present invention is a two-component design comprising a stabilizing lip configured to constrain movement in the general direction of compromised soft tissue.
