Clinical signs and imaging

Acute lameness associated with joint effusion and possible soft-tissue swelling in the fracture region are clinical signs of this fracture.

Diagnosis is by evaluation of a complete series of radiographic views of the fetlock joint.

Associated injuries

These fractures may be accompanied by significant injury of the associated collateral ligament. Therefore this structure should be evaluated ultrasonographically.

Fetlock subluxation or luxation are possible, but uncommon with this injury.
