Single condylar fractures of the distal femur in the dog

Nine dogs with single condylar fractures of the distal femur are described. In eight of the nine animals the medial condyle had fractured. Trauma is important in the production of this fracture as seven of the nine affected animals had a clinical history of having been suspended by the affected leg and struggling to free it. Clinically, pain and collapse of the medial compartment of the joint were the most obvious features. Confirmation of diagnosis was obtained by radiography. In the case of fracture of the medial condyle a lateral view showing caudal displacement of the condyle was most useful. Once identified the condyle was replaced surgically using combinations of pins and screws. Secure fixation allowed healing of the fracture and a successful outcome.
