  7. Laminitis: Rotation • In the normal position the coffin bone sits parallel to the hoof capsule • Rotation occurs when the coffin bone (P3) rotates away from the hoof capsule

  8. Laminitis: Rotation

  9. Laminitis: Rotation In severe cases the bone and hoof wall separate and the coffin bone may be displaced downward.

  10. Laminitis: Sinking • In the most severe cases the coffin bone can sink and penetrate the bottom of the sole. • This can lead to sloughing of the hoof capsule.

  11. What are the signs of LAMINITIS? • Lameness especially when turning in circles • Shifting weight back and forth. • Pain in the toe region when hoof testers are applied.
