An intervertebral prosthetic implant having a first endplate having a first surface configured to substantially engage with a first vertebral body and a second surface having an extension with a concave contact surface, the concave contact surface being spaced apart from the second surface. A second endplate is provided with a first surface configured to substantially engage with a second vertebral body and a second surface comprising a convex contact surface, and the second endplate having a securing element positioned along and above the second surface defining a first and second window on opposing sides of the second surface. The securing element extends along the width and length of the lower endplate and configured with an access hole. An extension portion extends from the first surface of the first endplate through the access hole of the securing element and contacts the second surface of the second endplate.

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.

A prosthetic joint includes: (a) a first member comprising rigid material and having a perimeter flange defined by an undercut groove, the flange defining a wear-resistant first contact surface having a protruding rim; (b) a second member comprising rigid material and having a perimeter flange defined by an undercut groove, the flange defining a wear-resistant, second contact surface having a protruding rim; and (c) a third member comprising rigid material positioned between the first and second members, the third member defining opposed wear-resistant third and fourth contact surfaces; (d) wherein the first and second contact surfaces bear against the third and fourth contact surfaces, to transfer loads through the member, while allowing pivoting motion between the first and second members; (e) wherein the flanges can deform elastically such that the first and second contact surfaces conform to the third and fourth contact surfaces.

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.

The present disclosure relates to an implant (100) for orthopedic stabilization. The implant (100) facilitates partial mobility between a pair of bones of a joint. The implant includes a first plate (10) on operative portion of first bone of the joint, a stem (15) extending from operative surface of first plate (10), a ball (42) formed on operative end of stem (15). A second plate (20) mounted on operative portion of second bone of the joint. The first cavity (44) configured on operative surface of second plate (20). An interconnecting plate (30) mounted on operative portion of second plate (20). The second cavity (45) configured on operative portion of interconnecting plate (30). A recess is formed by attaching second plate (20) and interconnecting plate (30). The recess configured to receive ball (42) therein facilitates partial mobility between the pair of bones in operative configuration of implant (100).
