This hoof was diseased inside and though it is obvious that the dark coffin bone shape reflects thin sucked up skin

What is interesting is the foot in just 2 white lightning treatments lost the sole concavity you see in the 1st picture and

sucked up to the coffin bone in the 2nd.  I believe the disease was removed and the sole had been sort of floating on it

and then collapsed into the structures.  You can see in the pictures on the top right toe quarters a depression.  This was

not from an abscess but from thin skin.
