A radiocarpal wrist joint replacement includes a radial member configured to be affixed to a portion of an end of the radial bone proximal to the wrist including a fixture to be affixed over a longitudinal aspect of the radial bone and a radial resurfacing plate having a substantially concave surface configured to be located at the end of the radial bone. A carpal capitate bone insert configured to be inserted and affixed into the carpal capitate bone. A bulbous component includes a first convex head and a second convex head, substantially opposite each other and connected by a neck between the first and the second convex head. The radial resurfacing plate of the radial member with the concave surface is configured to be operably coupled to the second convex head of the bulbous component so as to allow radial freedom of motion in the joint replacement.

The present disclosure provides for a wrist arthroplasty system and method that enable an expedient surgical procedure, maintain wrist motion, and reduce the likelihood of implant loosening. The system includes a capitate implant, a radial implant, and a resection instrument. The capitate implant includes a convex head formed to interface with a concave socket of the radial implant. The capitate implant includes a single stem formed to be secured within a patient's capitate bone. The radial implant includes lips formed to increase wrist joint motion and to help prevent dislocation of the capitate implant from the radial implant. The resection instrument may be used in combination as a measurement tool for determining the proper implant size, a guide for properly positioning the implants, and a trial tool for testing trial implant components before securing the final radial and capitate implants.
