Summary
A fracture of the proximal 1/3 of the ulna, with concurrent fractures of the proximal
radial physis and the distal 1/3 of the diaphysis of the radius occurred in a three-month-old,
male, neutered, Domestic Shorthaired cat. The ulnar fracture was stabilised with an
intramedullary pin. The proximal radial physeal fracture was reduced and stabilised
with two crossed Kirschner wires. The proximal radius was secured to the ulna with
an additional Kirschner wire. The distal radial diaphyseal fracture was stabilised
with a five-hole, 2.0 mm dynamic compression plate (DCP). Six weeks postoperatively
the cat was using the limb comfortably and demonstrated a full range of motion of
the elbow joint. There were radiographic signs of fracture union and the radioulnar
pin had migrated. The Kirschner wires were removed. Follow-up at 18 months postoperatively
revealed that the cat was using the limb normally without any lameness. A full, pain-free
range of motion was present in the joints of the left thoracic limb.
