Figure 6.1.9 Fragmented Medial Coronoid Process (Canine) CT
1y FS Golden Retriever with left thoracic limb
lameness of 6 months’ duration. The medial
coronoid process is small and misshapen,
has reduced density, and is clearly separate
from adjacent bone (a,b: arrow). Dorsal and
long‐axis oblique plane images show radioul­
nar incongruity with nonuniform joint space
width (c,d: arrow). The shorter length of the
radius relative to the ulna causes dispropor­
tionate contact between the humeral condyle
and proximal ulnar articular surface, leading
to subchondral bone sclerosis in the medial
aspect of the condyle (d: arrowhead).
