Abstract
A wrist arthroplasty system comprising a carpal implant for resurfacing carpal bones that is at least substantially arcuate in shape from a first end to a second end. The carpal implant includes a first carpal engaging surface, a second carpal engaging surface, a first carpal articulating surface, and a second carpal articulating surface. The first carpal engaging surface has an arcuate concave shape that at least substantially corresponds to a natural shape of a scaphoid bone. The second carpal engaging surface at least substantially corresponds to a natural shape of a lunate bone. The first carpal articulating surface is opposite to the first carpal engaging surface. The first carpal articulating surface has an arcuate convex shape. The second carpal articulating surface is opposite to the second carpal engaging surface.
