Figure 110C ——AP radiograph of the hand shows the characteristic “gull-wing pattern” of erosive arthritis affecting the PIP joints and, to a lesser extent, the DIP joints. Ankylosis of the fifth PIP is present. The inflammatory component of the condition is evinced by the central erosions present.

Figures 110D,110E —Coned view of the hip joint shows changes consistent with early osteoarthrosis, namely, minimal joint space loss, subchondral sclerosis and cyst formation, and marginal osteophyte formation.

110E— Marked osteoarthritis of the knee causes loss of the medial compartment joint space, prominent subchondral sclerosis and marginal osteophyte formation, and marked geode formation in both medial and lateral compartments.

Figures 110F–110H AP radiograph of the hand shows moderately advanced osteoarthritis of the PIP joints and, to a lesser degree, the DIP joints. Note the prominent hypertrophic osteophytes arising from the margins of the PIP joint of the ring finger.

110G —Osteoarthritis of the triquetral-pisiform articulation, although not frequently described, is seen reasonably often. An unusual association exists between osteoarthritis of this joint and primary biliary cirrhosis.

110H —Severe osteoarthritis of the shoulder is seen after septic arthritis. Marked joint space loss, subchondral sclerosis, and geode formation are present. Minimal osteophyte formation is evident at the inferior margin of the humeral head articular surface.
