PATHOLOGY

Detailed explanation-1: -Laminitis is inflammation and damage of the tissue between the hoof and the underlying coffin bone. In severe cases, it can progress to founder, in which the hoof and coffin bone are separated and the coffin bone can rotate, leading to severe pain.

Detailed explanation-2: -The term “Rotation” has commonly been used when the dorsal surface of the coffin bone stretches or separates its distal (bottom) attachment from the hoof capsule and appears to rotate downward. (Figure 1) As a rule, the coffin bone maintains its general position relative to the ground.

Detailed explanation-3: -The lamina provides support to the coffin bone. When separation occurs, typically the coffin bone rotates downward. As the coffin bone rotates downward, it presses the sole of the hoof, causing severe lameness. In severe cases, the tip of the coffin bone can penetrate the sole of the hoof.
