ABSTRACT:
Prosthetic wrist implants, instruments, and methods for implanting the wrist implant. A prosthetic wrist implant is disposed between a patient's radius and carpal complex bones. It includes a radial implant component having an elongated concave articulate front surface and a rear surface which is screwed into the radial bone. A carpal bone implant includes a base member with a front surface and a flat rear surface which is screwed into the carpal bone complex. Alternatively, a post may extend from either the back of the radial implant rear surface of the carpal bone implant, or both, and be implanted into the radial bone or the carpal bone respectively. An articulating bearing member having a flat bottom surface is fastened to the front surface of the carpal bone implant base member and an elongated convex surface slidingly engages the concave articular surface of the radial implant to permit articulation between the radial and carpal bones.
