Radiographs of both hands show malalignment of the metacarpophalangeal joints, most marked on the left, in keeping with subluxation. The bone density is normal. There is joint space loss and evidence of erosive arthropathy particularly evident at the metacarpophalangeal joint of the right long finger. Dense soft tissue calcifications are seen in the fingertips and along the ulnar aspect of the right wrist/distal forearm.
