Radiograph of a horse hoof showing marked separation of the hoof from the coffin bone with evidence of rotation and sinking, compatible with active severe laminitis. P2 designates the middle phalanx, or pastern bone, and P3 designates the distal phalanx, or coffin bone. The yellow lines mark the distance between the top and bottom part of the coffin bone relative to the hoof wall, showing marked widening of the hoof-lamellar zone, with the distal (bottom) of the coffin bone rotated away from the hoof wall.
