Abstract
A 2-year-old cat was presented with the complaint of acute-onset non–weight-bearing
lameness of the right forelimb. When examined, the cat was of short stature and had
multiple joint and cartilaginous abnormalities suggestive of chondrodysplasia. The
cause of the acute lameness was radiographically identified as a displaced osseous
fragment from the medial portion of the right humeral condyle. The features of the
osseous fragment were consistent with an ununited medial condylar ossification centre
of the distal humerus. Furthermore, a nondisplaced ununited ossified fragment of similar
appearance and size was present in the contralateral elbow. Surgical treatment by
excision of the displaced fragment resulted in a preinjury level of limb function
in the long-term outcome evaluation.
