Bovine Lameness and Podiatry
Pedal bone fractures
What is it?
Pedal bone fractures occur due to trauma and can be associated with breaks in the hoof capsule.
How to recognize it?
Most hoof cracks are not painful. Evaluate the digit for pedal bone fracture if the animal has severe foot pain but no evidence of white line disease, foot abscess or other significant lesion.
Radiographs are required for definitive diagnosis.
Pathogenesis
Fracture may occur due to trauma from the foot being trapped in slatted flooring, side rails or boards. Alternatively, P3 may be damaged due to infection and fractures may be pathological.
Treatment
The hoof wall will stabilize the fracture if motion is prevented. Elevate the injured digit by placing a block on the opposite digit. The digits can be wired together to minimize motion. If infection is present, debridement and drainage is necessary.
Healing will typically be by fibrous union.
