Trim Advice for Ribbon please Lavinia

Photo album attached with photos/x-rays. I had a difficult time putting my camera on the ground and not cutting off too much of the hoof, so please let me know if any of these are not sufficient and I will retake. 
Thank you

Hi Courtney,

Please see the directions on how to take hoof photos in the Wiki: https://ecir.groups.io/g/main/wiki#Photos-and-Hoof-Evaluation-Help.  We really need you to back the camera up enough so the cannon bone is in the picture as well as the hoof - this will probably put you a few feet away from the horse.

Hi Courtney,

I've added a couple of mark-ups to Ribbon's folder for you:

Generally, the current trim looks pretty nice - much better than what we normally see. The rads are showing a bit of tweaking that needs to be done, however, to really optimize it. The toes need to be pulled back further so that the breakover aligns with where the bony column needs it to be. The rads show that there is some bony column rotation on the RF (not a huge amount) but it has increased a bit from the rads taken on 6-8-2022. LF doesn't have bony rotation - it has a slightly broken back HPA, which is the opposite of rotation and hasn't changed from the earlier rads. Both show capsular rotation, which has increased a bit on both feet since the earlier rads. Capsular rotation is when the distance between the dorsal wall of the hoof capsule and the coffin bone widens as you travel from the coronary band down to the ground. Bony column rotation is when the pastern bones do not line up correctly, with the tip of the coffin bone tilting downward more. Both feet have sinking, RF more than the LF. Soles are thin on both, RF more so than the LF. Both also show side bone development, both more advanced on the lateral sides. Heels are slightly underrun, likely more on the LF (can't tell for sure as there are no sole photos available).

LF lateral composite: On the radiograph side, the pink line shows how the bones should line up, while the purple line follows where they actually sit. Note how the purple line dips slightly down.away from the pink line. That denotes a broken back HPA. The lime arrow denotes the need to provide more height in the back half of the foot, relative to the front half, to support and raise the the bony column up from "sagging" down. The pink line ends where the sole depth should be, which is beyond where the current sole depth ends, denoting the need to add more sole depth.Green line shows where the dorsal hoof wall should be (NOT a trim line)  - note how it runs parallel to the pink line. Blue line shows where to take the toe back to, with the blue X being the excess toe needing to be removed. Red arrow shows where the current breakover should be, while the intersection of the blue and pink line shows where it would be if the sole was thick enough. Breakover will shift back closer to the tip of the frog as the sole depth increases. Red line denotes nothing comes off the bottom of the foot along its length as there is already too little there. Orange line shows where the heels should be - a tad further back and more upright than they currently are and also parallel to the pink line. Yellow line #1 runs thru the coronary band, while #2 points to the extensor process. They should be overlapping, or at least very close together. The distance between them denotes the amount of sinking (distal descent). The too-forward toes and sinking are mechanically contributing to the thin sole.
On the photo side, the blue area corresponds to the Blue X on the rad - the excess toe forward of where the breakover should be. Green and orange lines correspond to the ones on the rad.

RF composite: On the rad, pink line again shows how the bony column should line up, while the purple line follows the actual alignment. Note how the purple line bulges ahead of the pink line, indicating there is some bony column rotation, with the coffin bone tilting a bit downward out of lining up with the bones above it. Green line extends the angle of the new growth coming in under the coronary band all the way to the ground and shows where the older growth below deviates away from that.This runs parallel to the pink line. Blue line at the toe is where to take the toe back to, with the blue X being the excess length there. Red arrow is where the breakover should be. Because the rad isn't a true lateral - it was shot from slightly below the foot, aiming upward so that part of the sole is visible, as are both the lateral and medial walls. The two blue lines along the bottom of the foot show where both heels should be lowered from mid-foot back, to lower the back half of the coffin bone and correct the rotation. The red lines from mid-foot forward to the pink line show where NOT to touch the sole in the front half of the foot. When done, the bottom of the foot won't necessarily be flat from front to back - which is perfectly fine. Yellow line #1 runs thru the coronary band, #2 points to the extensor process. The distance between them denotes the amount of distal descent (aka sinking). There is more than on the LF, which corresponds to the thinner sole and more discomfort Ribbon is having on that foot.
On the photo, the blue area at the toe corresponds to the blue X on the rad, which is the excess toe to back up. Under the heel, the blue corresponds to the blue lines on the rad, which is where to lower the heels some relative to the front half of the foot. Front half should remain untouched on the bottom as it's already too thin. Green an orange lines correspond to those on the rad.

Use boots and pads as needed for comfort, experimenting to find what combinations work best. That can - and many times does - change as the mechanics of the feet change. Make sure any boots have aggressive bevels added to the  treads at both the toes and across the heels to help set the breakover correctly.
