Abstract
A method of reconstructing a patient's wrist. A prosthesis is provided having proximal and distal assemblies. The distal assembly has a body with a U-shaped portion. The proximal and distal assemblies have surfaces that cooperate to guide movement between the proximal and distal assemblies. The proximal assembly is fixed to the patient's radius. The hand is prepared for placement of the distal assembly by removing cartilage against a plurality of carpal bones without significantly altering the configuration of stable volume of at least one of the patient's carpal bones in the first carpal row. The U-shaped portion of the body is placed against a plurality of bones in the first carpal row. Separate locations on the body are secured to a plurality of carpal bones.
