Re: Lavinia, request for trim markups
I've added mark-ups to Callisto's album:
Comparing the radiographs from 8-2020 to the most recent 2-2021 set shows that there has been very little improvement in the trim during that period. Both sets show horizontally long toes, thin soles, underrun heels and sinking. The HPAs appear to have become more broken back in the Feb views. frogs are somewhat atrophied and elongated, indicating that heel-first landings aren't occurring regularly. Part of the reason Callisto may be hesitant to use his frogs is that the the sulci are split up into the live tissues, which is going to be painful To correct the issues, the trim needs to back up the toes and move the heels back while maintaining all the vertical height. Nothing can be removed from the soles, bars, heels or frogs. Soaking the feet in 50-50 ACV + water, then injecting a 50-50 mixture of athlete's foot cream (with clotrimazole) + triple antibiotic cream containing a pain-blocking ingredient will help treat any possible thrush/fungus/infections that may be hiding up inside. Once the cream is injected, plugging the opening with some cotton can help keep the meds inside while keeping dirt out.
LF lateral composite: On the rad, the pink line shows how the bony column should align and the line extends down to where the breakover point needs to be. This point is below where the current sole stops, due to the sole being thin. Purple line follows the actual alignment. Note how the purple line dips back and down, away from the pink line. That's a broken back HPA. Green line follows the angle of the new, healthier wall growth coming in under the coronary band and is parallel to the pink line. Blue line is where the toe needs to be brought back to, with the blue X being the excess length. Red line along the bottom indicates nothing should come off the bottom of the foot this line should actually be sloping downward as it moves from front to back to indicate the need to add more height to the back half of the foot. Yellow line #1 runs thru the coronary band, while #2 points to the extensor process. These lines should be overlapping, or at least very close together. The distance between them indicates the amount of sinking. The sinking+ long toes are combining to keep the soles thin.
On the photos, the green line corresponds to the green line on the rad. This is only a visual marker, NOT a trim line. Orange line shows where the heels should be found. Blue area corresponds to the blue line and X on the rads = toe that needs to be removed.
LF dorsal: Green line follows the angle of the new growth toward the ground. Blue is the remaining flared wall that needs to be removed, then beveled under to remove it from ground contact until the wall can grow in with better connections.
LF sole: Red circled area ia the sulcus split that needs to be regularly treated until it has healed. Blue solid line is where the perimeter of the hoof should be at ground level. Blue hashed areas are what needs to be removed in the toe length and beveled out of ground contact everywhere else so that the walls can grow in well-attached. Orange rectangles are where the weight bearing should be set - on the bar-wall juncture, without lowering it. Rasp the outer wall away from this area so it is no longer weight bearing. This will encourage the heels to drop down, rather than running forward. Add rockers to the backs of both heels. Leave the bars, sole, frogs alone as they need to add depth and callousing. See here for more info:
RF lateral composite: Same general guidelines as the LF. The HPA looks better but the foreleg also wasn't fully weight bearing at the time the view was shot, so that improves the HPA to some degree. The lateral photo isn't a true lateral - it's more of an oblique, so the toe length isn't as obviously extended visually. Still needs to come back.
RF dorsal: Blue is the slight lateral flaring that remains.
RF sole: Same discussion as the LF.
There are no photos of the hinds but it is likely the same issues exist there, only they may be more subtle.
He should remain in boots and pads - which will both protect his thin soles/frogs and will provide pressure-and-release stimulation to help rehab them - until he can move out willingly with solid heel-first landings.
