Rasping the hoof wall in laminitis.
I was chatting to Prof Pollitt last week about the laminar wedge.
He commented that rasping the hoof wall to reduce its thickness is like unlocking the prison that is containing the laminar wedge. By releasing that pressure the wedge will not have such devastating internal effects as when encapsulated by the wall prison it has nowhere to go but inwards.
My lightbulbs went off in my head!
I understand that the inward pressure and growth of the laminar wedge is catastrophic to the coffin bone.
The laminar wedge is a chaotic tissue formed from epidermal lamellae and white line and is an uncontrolled growth of cells without the correct instructions for cell division and growth.
The wall will diverge due to the lever forces on it as the horse walks- per Prof Pollitt. If the horse was in outer space the laminitis would still occur but there would not be any wall divergence or bone divergence as that’s all due to biomechanically forces.
Wow!
Interesting thoughts.
