7 month old Labrador Retriever with lameness

Findings

ELBOWS There is mild subtrochlear sclerosis of both elbows. There is a focal contour defect at the articular surface of the medial humeral condyle on the cranial caudal projection bilaterally. There is evidence of underlying subchondral sclerosis at this site.

LATERAL SHOULDERS: There is a focal contour defect and radiolucency in the subchondral bone of both shoulders. In the left shoulder, there is also an ill-defined mineral body present at the caudal humeral head. The right shoulder appears to have a mineralized linear cartilage flap associated with the defect.
