23-A2   Simple extraarticular fracture of the distal radius

23-A2 is an extraarticular simple fracture of the distal radius and ulna.

Generally, this fracture is associated with a traumatic event. Toy breeds are more prone to this kind of fracture compared to large breed dogs.

In immature patients the fracture may involve the growth plate.

Clinical signs observed for 23-A2 fractures are:

• Pain
• Lameness
• Crepitus
• Swelling
• Carpal joint instability
  
  Note: Instability is the result of either the ulnar fracture itself or damage to the substance of the lateral collateral ligament. It is extremely unusual to see both in the same patient.

Craniocaudal and mediolateral views of the antebrachium are needed.
