Re: Update on Granite
I've added mark-ups to Granite's album here:
You've made a good start on addressing the areas that need attention with backing the toes and starting to move the heels back a bit. The general goals are to back the toes hard in the horizontal plane, move the heels back considerably to get his base of support back under him (esp. behind) and pull the flares in. I'm assuming the small, white bead on each of the xrays is marking the location of the coronary band. Based on that, there is distal descent (aka sinking) evident in all feet. This also means that although it appears as if there is a lot of excess vertical height to work with, there really isn't . Sole depth is barely adequate so need to preserve it when making adjustments. The hoof-pastern axis is just slightly broken forward on all four with the rears being worse than the front. This means the heels need to be lowered just a bit in relation to the front half of the foot. The medial-lateral balance appears to be pretty good all around.
RF lateral xray: Yellow lines are the coronary band (1) and the extensor process(2) and should align or be close together. The distance between them denotes the sinking. Green line follows the angle of the new growth of the hoof capsule under the coronary band and where the toe needs to be backed and beveled under to provide the proper breakover for the coffin bone. Blue is where the heel needs to be lowered.
RF lateral: Green is following the angle of new growth. Blue is where the heels need to lowered. Red is the area on the bottom NOT TO LOWER when working on the heels. The idea is to tilt the foot rearward to realign the hoof capsule to the internal structures. If you follow the current trim plane there is no net change. WHite area is an idea of what needs to be removed. Rasp the toe back from the top, perpendicular to the current angle of the hoof capsule at the toe and bevel under. Advise leaving the excess dorsal wall above/back from this point alone and allowing it to grow out over time. The current material in this area is laminar wedge, sort of like scar tissue, that isn't as organized or strong as healthy wall connections are. Thinning it to make the hoof capsule appear pretty and normal removes some protection and stability from an area that is already compromised.
RF lateral adjusted: This is an idea of what the hoof capsule should actually look like as opposed to it's current conformation.
RF lateral oblique: Green is an idea of where the excess material is. At ground level, everything in front of this line is causing lever forces to tear apart the laminar connections with every step that Granite takes.Blue is where the heel buttresses are currently located, Yellow is where they should be - even with the widest part of the back of the frog.
RF sole: Yellow is a general idea of where the actual hoof print should be. Toe needs to come back considerably and flares need to be brought inward. Preferably, do this from the top so as to only bring things back and in rather than lower them. Align the breakover with the center of the canon bone and pastern to stay true to the bony column alignment. Red is about where the true tip of the frog is. The frog has migrated forward along with the heels, following the pull of the overly long toe. Just need to note this event rather than necessarily chop off the excess unless it is just dangling there. Green is where the heel buttresses are now, blue is where they need to be. This is going to be done over time as there isn't enough vertical height available to just fix this in one trim now. There is overgrown frog and cuticle hiding the actual heels toward the back - as the heels are moved rearward, this material will wear off, sometimes it may need some gentle encouragement from you as well. Let Granite tell you how much he can tolerate in any one session. Best is to do small amounts regularly (weekly) as opposed to trying to move them back in large amounts every 5-6 weeks. Purple is the overgrown bars, curving outward, pooling over the sole and melding with the outside walls to cover the true juncture of the bar and sole in the heels. As you rasp the heels backward, also gently work to open up the area between the bar and wall to find the buried sole underneath. There is a twist to the hoof capsule. likely due to the heels running forward unevenly over time. As the heels are corrected and the toes brought back into alignment with the correct breakover point, this should also correct.
LF: Same idea as RF but without the twist.
RH/LH lateral xrays: Same as RF but there is a bit more forward tilt to the coffin bone.
LH dorsal: Yellow arrows are where the walls are flaring considerably, more so medially than laterally. Green is a bulge in the excess toe that needs to be brought relatively further back than the adjacent areas when backing the toe as it is creating more pressure.
LH sole oblique: Yellow lines folow the angle of the horn tubules as they are growing out and all the lines are aligned at the top with the same "growth ring". Note how far forward the heels are and that they are growing almost horizontally. Also note how compressed the growth at the toe is from the pressure of the excess toe length. The new growth is so finely compressed that it is dificult to see how steep the angle really is compared to the older wall beneath. Purple is where the heels are now, blue is closer to where they need to be. You can really see the frog overlapping the hoof capsule and the heel wall buried underneath.
LH sole: Green is about where the hoof should be (actually, further back than that in once things get more functional). Need to bring the toe back considerably and the flares inward as well. Purple are the current buttress locations, blue are where they need to be. Red is the true tip of the frog. Pink are the bars pooling and burying the sole, pushing the walls to flare outward in the rear of the foot and hiding the true location of the heel-bar juncture.
Saphira (working on her pix now) has similar issues but her heels in front are considerably more under run and the hoof capsules show markedly more twisting.
