My 9 year old TB had a mechanical founder of 8-10 degrees in RF this May. It was the result of previous farrier ignoring white line for months. He had to have 40-50% of his hoof wall drimmeled off to stop the growth of the fungus. Obviously with that much hoof missing he cannot go without shoes, so new farrier who specializes in corrective shoeing began putting bar shoes on and backing up the toe and things were going well.
Fast forward 4 months after the farrier apprenticing under the initial corrective farrier has taken over shoeing, and my horse started getting even more lame, to the point of 3 legged lame with daily bute. The new farrier talked with the other farrier and decided to put a backwards shoe on the RF. Told us it should help within a week if its going to. 2 weeks later and still very lame on bute we made a checkup appt with vet to rexray. He has rotated even more. I was not able to be there when the vet xrayed to learn the degrees now. The two farriers met to try a new setup to make him more comfortable so he is now in a leather pad and a bigger bar shoe to give him lots of support.
Vet told me he will never jump again with as severe as his rotation is now. I am still devastated by this as we had just started competing in 1.0m jumpers and were finally moving up the levels.
Has anyone had any success of a horse jumping after rotation? He was my heart horse and its been difficult to come to terms with him possibly not ever being sound enough to ride.
