Re: Vertical split in hoof wall

Lavinia Fiscaletti

Hi Barbara,

I've added a few mark-ups to Mist's album:

You are dealing with a quarter crack, which results from significant imbalances in the hoof capsule that end up creating a crack at the weakest point between competing improper mechanics. The crack runs up toward the coronary band between horn tubules. Correcting it requires correcting the trim imbalances, then maintaining a tight trim until the crack grows out. That can take a year or more.

The toe is significantly run forward, heels are underrun and there is major wall flare all around, with the lateral wall flaring more than the medial one. HPA is broken back. The fix is to back up the toe thru what appears to be the white line at ground level, removing the flared material from ground contact all around so that there isn't constant leverage being applied to the detached walls. Leave the soles and frogs alone. Only remove any crumbling leading edges of the bars at a trim as at present, the bars are helping to support the entire foot due to the damage present in other structures.

LF dorsal: Green lines follow the angle of the new growth down to the ground. Blue areas are the flared wall that needs to be removed.

LF lateral: Again, green line follows the angle of the new growth coming in under the coronary bad toward the ground. This is a visual marker, not a trim line. Blue area is the toe that needs to be removed. Orange line is another visual for where the heels should be located. Can't move them there at this time as there is already too little vertical height in the back half of the foot relative to the height in the front half.

LF lateral sole plane: The dish in the dorsal wall is seen much more clearly in this view. The green line is the same as on the lateral view, with the blue area the excess amount of toe ahead of where the breakover should be located.

LF sole: Everything outside of the blue solid line should be out of ground contact (blue hashed areas). Yellow hashes run along the leading edges of the bars, where it appears they can be tidied up a bit more - but don't get over zealous, as those bars are structurally extremely important now due to the rest of the support structures being compromised.

The rest of the feet are likely also similarly compromised (I could see part of the RF in one photos), so the trim needs major adjustments across the board.

Please let me know if you'd like more in-depth work on the rest of the trim.
