Premature closure of the distal radial physis in two dogs.

Premature closure of the distal radial physis was diagnosed in two dogs. In one dog, the premature closure was symmetric; in the other, it was asymmetric. Lameness, elbow subluxation, distended elbow joint capsule, forelimb muscle atrophy, and a shortened radius and ulna had developed in each dog. Carpal valgus and outward rotation of the paw had developed in the dog with asymmetric closure. Surgical treatment resulted in marked improvement of forelimb function in both dogs.

Renal and ureteral duplication in a dog.

Duplication of a kidney and ureter in an 18-month-old male English Bulldog was demonstrated radiographically and was confirmed surgically. Urinary tract infection had been a problem for a year. Antimicrobial therapy resolved the clinical signs of urinary infection but did not eliminate bacteriuria.

Asynchronous growth of the canine radius and ulna: effects of retardation of longitudinal growth of the radius.

After 2,000 rads of x-radiation to the right distal radial physis of eight 70-day-old dogs, the longitudinal growth of the right radius was retarded 42.1% when compared with the growth of the nonirradiated left radius. Asynchronous growth of the right radius and ulna resulted. The gross and radiographic changes that occurred over the subsequent 75 days were described. Subluxation of the humeroradial and humeroulnar joints occurred and was first observed 31 days after irradiation. By 75 days after irradiation, the radius was puller 7.8 mm distally by the radioulnar ligament. However, subluxation of the humeroradial joint was minimized by accelerated growth from the proximal radial physis and articular cartilage. Acceleration of growth also occurred at the distal radial articular cartilage. Growth from the distal ulnar physis and styloid process was retarded. It was thus apparent that after retardation of growth from the distal radial physis, considerable adjustment occurred in the relationship between the radius and the ulna and also in growth from their other physes, which reduced the deleterious effects of the growth retardation.

Tracheal osteochondroma in a dog.

A young female Labrador Retriever-type dog had a 4 1/2-month history of respiratory distress, which eventually became severe, leading to cyanosis. Physical examination suggested an upper airway obstructive lesion, which was confirmed by bronchoscopy and radiography to be a mass in the thoracic portion of the trachea. The mass was removed surgically and, on histologic examination, was found to be an osteochondroma. Six months after surgical extirpation, there was no indication of recurrence of tumor.

Retinal dysplasia associated with skeletal abnormalities in Labrador Retrievers.

The clinical, radiographic, and pathologic features of skeletal and ocular dysplasia in 6 Labrador Retrievers were studied. Abnormalities in the appendicular skeleton included retarded growth in the radius, ulna, and tibia; ununited and hypoplastic anconeal and coronoid processes; hip dysplasia, and delayed development of epiphyses. Ocular changes were characterized by retinal dysplasia, with retinal detachment and cataract formation. Dogs from 4 litters were affected.

Asynchronous growth of the canine radius and ulna: effects of cross pinning the radius to the ulna.

Kirschner wires were introduced into the diaphyseal region of the radius and the ulna in 4 Australian shepherd crossbred pups, and change in relationships between the bones during growth was demonstrated. The contributions to longitudinal growth of the radius from proximal and distal growth plates were also calculated. Over the period of growth, the proximal growth plate contributed approximately 40% of the length of the radius. A marked shifting of the radius in relationship with the ulna occurred. This normal shifting between radius and ulna was prevented in 6 dogs by cross pinning the radius to the ulna at 90, 111, 142, and 168 days of age. Marked change was produced in the elbow joint, where altered relationships of articular surfaces of the radius and the ulna resulted in displacement of the humeral condyle from the trochlear notch of the ulna. Changes in dogs cross pinned at 90 and 111 days of age were most severe and consisted of severe degenerative changes which were most marked on the lateral side of the distal half of the trochlear notch of the ulna.

Primary hyperparathyroidism in a dog.

Anorexia, severe skeletal demineralization, and muscular weaknesss developed in a 9 year-old Collie. Hypercalcemia, hypophosphatemia, and nephrocalcinosis were found on clinical evaluation. The surgical removal of a parathyroid adenoma was followed by profound hypocalcemia that was unresponsive to calcium therapy, and the dog died. The persistent hypocalcemia was attributed to increased deposition of calcium in mineral-deficient bone.

Ascites associated with intrahepatic arteriovenous fistula in a cat.

A 1 1/2-year-old male domestic short-haired cat with ascites was found to have an intrahepatic fistula between the hepatic artery and portal vein. The diagnosis was made by means of angiography. The ascites was attributed to portal hypertension caused by the fistula.
