Re: LAVINIA/ MARKUPS for tiko
I've added the mark-ups to Tiko's album:
Unfortunately, there have been no changes made to the trim since the reads were done back in Nov 2019. Although the sole depth has increased slightly, the coffin bones are still ground parallel, with the HPAs remaining significantly broken back. Tiko's heels are underrun and his toes are too long horizontally. The feet have basically squished down, with the entire hoof capsule pushing forward out from under the leg and the heel bulbs have dropped down and been compressed out behind the heels. The goal of the trims needs to be to get the toes backed up while working to encourage the heels to stand up straighter so that the entire hoof capsule can settle back in under the leg and support the horse correctly.
LF dorsal: The green line follows the angle of the new growth to the ground. The blue area is some slight lateral wall flaring that can be removed entirely.
LF lateral composite: On the radiograph, the pink line shows how the bony column should be lining up - where it ends is where the sole depth should be. There should be no hoof at ground level beyond this point. The purple line follows the actual bony column alignment - note how it drops back and away from the pink line = broken back hoof-pastern axis (HPA). The green line running down the dorsal wall is only a visual marker - NOT a trim line. Once the bony column is properly lined up, this line will run parallel to the pink line. Blue line at the toe is where the toe needs to backed up to, with the blue X being the excess horizontal toe length. Red line denotes where the bottom of the hoof should be if there was a proper amount of sole depth. The lime line at the back of the foot shows how the heel bulbs would be if they hadn't squished out behind due to the heels collapsing forward.
In the photo: the green line is the same as the one on the rad. Blue area corresponds to the blue X on the rad. The orange line shows where the heels should be located over time.
LF sole: Due to the shoe, you can''t see most of the bottom of the foot. The blue hashed lines correspond to the blue area on the lateral rad and photo. This line is likely behind where the "white line" appears to be at ground level. Need to remember that the white line is a seam that stretches along with the sole and rest of the foot, so it's distorted as well. Please have a read here for more specifics:
Even tho they need to be moved back, the heels need to be left alone for now as there is no extra vertical height available to work with. Rather, they need to be encouraged to stand up straighter over time. Frogs and sole should be left alone. Only lightly address any areas along the leading edges of the bars that are crumbling or already detaching. More specifics here:
See esp. figures 2 and 3.
RF lateral composite: Same discussion as the LF.
RF sole: Follow the discussion for the LF.
LH lateral composite: Similar to the fronts but there is a bit more sole depth. On the rad, the blue X is the extra toe length that needs to be removed. Because the foot was pulled a bit forward when the view was shot, the HPA looks a tad better aligned, so the pink and purple lines appear more closely aligned. If you pushed that foot back so he was standing squarely on it, the HPA would be worse.
LH sole: Same idea as the fronts - shorten the toe horizontally at ground level (blue hashed area).
RH dorsal: Green line follows the angle of the new growth. Blue area is the slight amount of lateral wall flare that can be removed. The maroon line highlights the medial wall being a tad longer than the lateral one. comparing both of the collateral groove depths at their deepest points will help to double check this:
RH lateral: Blue area is the excess toe length. Orange line shows where the heels should eventually align. Green line is only a visual marker.
RH sole: Follow the discussion for the other three feet.
While putting on shoes will physically lift the soles off the ground, it creates the clearance at the expense of hanging the horse entirely from its lamina by removing the soles and frogs from doing their share of the load bearing. Shoes will also apply constant pressure to the already crushed under heels, never allowing them to relax down and stand up. Padded boots will allow for support across the entire bottom of the feet, while providing pressure-and-release that stimulates sole growth and increases overall foot function.
