Radiographs of the wrists and hands: osteoarthritis of the distal interphalangeal, proximal interphalangeal, and metacarpophalangeal joints with calcium pyrophosphate dihydrate deposition disease (CPPD-CDD). The hook-like drooping osteophytes on the radial aspects of the heads of the metacarpal joints and ulnar bones, destructive symmetrical bilateral arthritis of the wrists with scapholunate advanced collapse, radiocarpal joint space narrowing, and subchondral sclerosis are all characteristic features of CPPD-CDD.
