Wrist arthroplasty system and method

A wrist arthroplasty system comprising:

• a capitate implant including a capitate stem extending from a carpal surface of a head portion, wherein the head portion includes a convex surface opposite the carpal surface;
• a radial implant including:
• a base component,
• a radial stem extending from a first side of the base component, and
• a socket extending from a second side of the base component opposite the first side, wherein the socket includes two lips forming a concave opening adapted to interface with the convex surface of the capitate implant;
• and
• a resection instrument including:
• a distal radius guide including a trial socket formed integrally with a reaming guide, wherein the trial socket is configured to substantially replicate the socket of the radial implant, and wherein the reaming guide includes an opening sized according to the trial socket,
• a guide block including a plurality of holes each adapted respectively to receive a fixture instrument, wherein the guide block is configured to receive a depth control instrument, and
• the depth control instrument including an adjustment knob, wherein the depth control instrument is configured to removably engage with the guide block such that, when engaged, rotating the adjustment knob causes the depth control instrument to translate relative to the guide block.
