[Surgical treatment of a Monteggia fracture in a cat]

A one-year-old, intact female Sphinx cat was presented with severe lameness in the right front limb following a fall. Orthopedic examination revealed grade four lameness with hematoma and severe pain around the elbow. Radiologic examination revealed a type I Monteggia fracture. The ulnar fracture was treated with plate osteosynthesis, while the radius head dislocation was fixed with a positional screw inserted between the ulna and radius. The cat was kept on cage rest for eight weeks. Recheck radiographs were taken four and eight weeks after the operation. At the time of the second follow-up examination, the cat was free of lameness and the positional screw was removed. A few days after this second surgery, the cat was able to return to normal activities.
