Fig. 4-127 A 7-year-old female Cocker Spaniel was brought in for acute
right forelimb lameness that localized to the elbow. A, Radiographic findings
include an intercondylar to lateral supracondylar fracture of the distal right
humerus. B, The same dog was evaluated for a similar lameness in the left leg
7 months later. Radiographic findings include a separation of the lateral
humeral condyle from the rest of the humerus that led to a distortion of the
articular surface. Fragment displacement is proximal and lateral and there are
some additional chiplike fragments at the proximal aspect of both fractures.
Diagnosis: Incomplete humeral condyle fusion resulting in intercondylar
fracture(s).
