Re: Trim Mark Ups Needed For Banjo

Lavinia Fiscaletti

Hi Kay,

I've added mark-ups to Banjo's album:

At quick glance, Banjo's trim doesn't appear to be too bad but when you look closely, it has some issues that are very common. His toes are too far forward, along with his heels being underrun  These problems tend to go hand-in-hand. The radiographs show distal descent (aka sinking). These issues have been present in all the rads. His HPA is significantly broken back, which is new, as in the 3/2022 rads, the bony column alignment was fine. This additional problem is due to his heels having been lowered when there was no need to do so. Sole depth is adequate but there is none to spare, so the trim needs to leave the soles untouched.Frogs are being over-trimmed, with the waxy, immature frog being exposed. Need to allow calloused frog to develop, rather than striving to create a neat and pretty looking frog that doesn't function well. Be very targeted in what is removed - loose tags and isolated flaps should be snipped off but that's it. There is some mild flaring but nothing extreme. Goals of the trim should be to bring the toes back so that the breakover moves closer to the tip of the frog and more in line with where the bony column needs it to be. This will require backing thru what appears to be the white line at ground level. Although they need to be moved back further under the leg, the heels don't have the vertical height available to do so. Instead, rocker the backs of the current buttresses and remove the walls in the heels from load-bearing. This will encourage the horn tubules in the heels to relax down and back while preserving the vertical height. Here are links to more in-depth info on these concepts:

LF DP60: Solid blue line shows where the toe needs to be brought back to, with the blue hashes being the excess toe.

LF lateral rad: Pink line shows how the bony column wants to line up and ends where the breakover should be. The purple line follows how it actually does align. Note that the purple line dips back and down, away from the pink line - that's a broken back hoof-pastern axis (HPA). Blue line is where to back the toe to,with the blue X being the excess toe that is ahead of where it needs to be. Red line denotes that there needs to be more heel height and that nothing should be removed from the bottom of the foot in that area. Yellow line #1 runs thru the coronary band, while #2 points to the extensor process. The two should overlap, or be close together - the distance between them denotes the amount of sinking.

LF dorsal: Green line follows the angle of the new, healthier growth down toward the ground. Blue area is some remaining flaring that can be removed. 

LF lateral: Green line shows how the dorsal wall should line up. Orange line shows where the heels should be lining up. Neither is a trim line - they are just visual markers. Blue area corresponds to the blue X on the rad =  the excess toe length that needs to be removed.

LF sole: Solid blue line is where to bring the foot in to, with the blue hashed areas being the excess, damaged material that should be removed. Lime lines are on a piece of dried up frog that can be removed. Bevel the walls out of ground contact all the way around, esp. in the toe from 10 to 2 o'clock.

RF DP60: Again, solid blue line is were the toe should end, so everything beyond it needs to be removed. Note that the toe crack is beyond where the toe should end, so removing the excess will also remove the crack.

RF DP: Green line follows the angle of the new growth down to the ground, with the blue area being some wall flare that should be removed.

RF lateral rad: Same idea as the LF. The orange line shows the where the heels should be.

RF lateral: Pink, orange and green lines are the same as on the rad, with the blue area being the excess toe length.

RF sole: bring the entire perimeter inward to the solid blue line. Note that the broken out out area of wall will be gone at that point. Bevel the walls out of ground contact all around, esp. in the toe from 10-2 o'clock.

LH dorsal: Green line follows the angel of the new, healthier growth to the ground. Blue area is some remaining flaring that can be removed. Also check the medio-lateral balance, as it looks like the medial side is somewhat higher than the lateral one.

LH lateral: Same idea as the fronts, with the pink line showing the bony column alignment, the green line showing where the dorsal wall would be and the orange line where the heels should be. Blue area is where to take the toe back, esp. at ground level.

LH sole: Take the entire perimeter inward to the solid blue line. This includes taking the walls in the heels out of weight bearing as well, so that the horn tubules can relax down and back. Bevel all around, esp. at the toe from 10 to 2.

RH lateral: Same discussion as the other three.

RH sole: Follow the discussion for the other three.
