A 4 1/2-year-old male Cocker Spaniel was admitted to the Stange Memorial Clinic on Oct. 17, 1949, with a history of having its left front leg broken one day previously, in some undetermined manner. The .dog was lame on that limb and evidenced pain when palpated. Swelling and crepitatons were felt at the distal end of the left humerus and proximal ends of the radius and ulna. The entire joint region was distorted. Fluoroscopic examination revealed clean fractures of both humeral condyles from the shaft of the humerus, with their displacement to each side. The shaft, under tension of the extensor muscles, was pulled ventrally to a position where it rested upon the dorsal aspect of the olecranon process, immobilizing the joint.
