Distsal P1 with P3 assymetery

[calshoer]

OK heres a pic I was looking for .(I have slides all ower the office and have to find and then scan them so it takes while) This is a mare who was about 16 at the time this was taken.She shows the assymetry in the distal end of of P1 that I talked about earlier, with a noticeable remodelling of P3 to "make up the disparity" in the shape of P1. I think it is natures way of responding to uneven stress in the coffin bone and thereby re shaping the bottom of P3 to try and get it flat to the ground. A lot of the older horses who have this P1 shape also show this kind of change in P3. This one has a good looking P2, not crooked or a paralellogram, but just sitting tilted because of the angle of the other joints. I don't worry about trying to get this kind to land flat.They won't. As long as those joints are loaded evenly across the joint space, they are happy and I am happy. Patty

Good pic of an older horse, I won't critique as if it was sent to me to shoe, it's not my calling on this board. The bony changes are good references. :D

Thanks, this was an intertesting case. I tried to find a slide of the lateral to but to no avail..the originals are in Ca with the vet.

She had a signifiant club foot on this side, and slammed it down lateral side first. There was remodelling of the entire anterior portion of the solar margin of P3 from the widest part of the bone forward. It was flat on the whole toe, so when you observe this Xray looking through the bone from front to back it creates the "box" look you see on the AP. If you had taken the bone out of the foot and set it on the table it would have made a nice rocking chair.

I wlll go on about the shoeing for her since isn't that is why we are all here? She presented with navicular pain, and stumbling. After the films I first trimmed her following her sole plane, and shod her with full EDSS system and rails. I can't remember how tall of rails it took to get a heel landing at that time , but they were eventually let down to lower rails.
Over a couple of shoeings She graduated down to simpler aluminum NB with wedge frog support pads, placing the breakover diectly under the tip of P3. She still landed lateral side first, but the lameness and stumbling went away. The dissapearance of lameness was about three or four weeks after the initial shoeing , but the stumbling was gone imediately after the shoeing. Patty
