Not sure where the idea that the horse has contracted heels comes from. There's no sign of that in the one picture where you can only kind of half see the heels. Also the sunken p3, really guys? Where do you get these ideas from?
I don't understand how you get the idea there's no sign of any contraction. Heels do look a little contracted in that one pic, also the one I attached from her other thread. They're not terrible in that regard tho. Perhaps, as with the rad you posted about P3 low in the capsule, it's a matter of degrees, that you don't recognise lesser effects. I agree you can't tell that from the rads tho. I also agree that you can't tell about hotnailing, but I wouldn't think so from what we've seen.
The pic of the hoof front on & the second lateral view rad is what tells me that (very likely) P3 is a bit low in the capsule. In the pic, you can see above the coronary border looks a bit swollen looking, esp on the left hand side. I marked the rad to show the discrepancy in level of the extensor process of P3 & where *I think*(as said, can't be certain of accuracy without marking) the top of the coronary border is. In addition, the ski tip on P3 tells of long term increased pressure/thinner sole at the toe.
In the d/p view, I've outlined the distal edges of P3, to show how uneven it is. Also the blue lines show the uneven joint spacings, and also the uneven distance on either side of the wings of P3. If you look on the other thread, you will see m/L imbalance there too. I think, from the rads, this looks to be a long standing imbalance, not, as I think we discussed Madison(didn't re-read last thread), that it was possibly the recent farriery that caused it.
My concern about the erosion to P3 is what I marked in the skyline view rad. After looking again at the other thread, that's not in the region of the current seedy toe *if the rad & pic are the same orientation. Perhaps that was a previous problem. As mentioned, as it depends on the lucency of the radiograph, can't be sure as to how much the transparency of the edges of P3 accurately reflects bone density either, although it appears there is some.
So all in all Naph, as said, I appreciate we can't be sure of details, accuracy, and as said, the degree of P3 being low in the capsule, the degree of contraction is anything but severe, but given other aspects as well, I don't understand how you get the idea the hoof pics & xrays look 'good'.
