Fractures of the ulnar body may occur in horses of all ages and are usually the result of a kick by another horse. Typically the fracture is minimally displaced and stable. These fractures are rare in the author’s experience.
The horse usually presents with moderate to marked lameness. The lameness usually dissipates with anti-inflammatory treatment. These fractures are usually not markedly displaced, and therefore the triceps mechanism is not disrupted and the patient does not have a prominent dropped elbow appearance. With the ability to extend the elbow, the patient can fully extend the carpus and therefore stand on the affected limb. These fractures can be closed or open.
