The laminae are what suspend the coffin bone inside the hoof capsule. In this phase rehabilitation can be much faster. As laminae are destroyed by their blood supply being cut off, the coffin bone is no longer firmly attached to the hoof capsule.
Poor circulation produces weaker laminae.
A hoof in this already weakened state is less able to withstand laminitis triggers. Triggers that might only lead to transient inflammation and no rotation in a healthy foot can lead to inflammation and wound secretion, which exerts hydraulic force that pushes the white line apart. A healthy hoof with normal circulation will be better able to clear inflammation secretion from the hoof. Hoof abscesses are a frequent result of laminitis . Laminar tissue dies as the result of circulation being cut off.
