Left hand: There are extensive erosive changes of the distal articular surfaces distal radius and ulna, as well as of the carpals and carpometacarpal joints. The radiocarpal, intercarpal and carpometacarpal joint spaces demonstrate severe uniform loss of joint space.
Right hand: There are mild erosive changes involving the scaphoid in the region of the scaphoid tubercle, as well as marginally throughout the interphalangeal joints; however, the associated joint spaces are maintained.
