Abstract: A modular resurfacing implant for a radioscaphoid joint of a wrist includes a stem and an articular component coupled to the stem. The stem includes a threaded body for implantation into a distal radius and a connection member positioned at a second end of the stem. The articular component includes a body member configured to resurface a scaphoid fossa of the distal radius. The body member includes a concave top surface matching a curvature of the scaphoid fossa and a bottom surface having a post extending therefrom that is configured to mate with the connection member of the stem. The articular component is configured to resurface the scaphoid fossa while leaving a lunate fossa of the distal radius intact.
