11y FS Labrador Retriever. Images of the stifle are ordered from proximal to distal. On unenhanced images, there is marginal osteophyte
production at the level of the trochlear ridges (a: arrows), fabellae (b: arrows), and tibial plateau (c). There is a semicircular osteophyte
surrounding the caudal portion of the long digital extensor tendon (c: arrow). Contrast‐enhanced images show thickening of the synovium
(d–f: open arrows).

8mo German Shepherd Dog with left thoracic limb lameness. There is an ununited anconeal process in the left elbow (a,c: arrow). There
are marginal osteophytes surrounding the lateral and medial aspects of the joint (a,b: arrowheads). The medial coronoid process of the
ulna is also fragmented (c: arrowhead). The subchondral bone of the ulna is sclerotic (c: open arrowhead).
