Do you suppose that's what they mean, that his fused ankle will make him step wonky on that side but that they think it should be strong?
I should imagine that it would be strong enough, but I could see the angle of the fetlock being slightly different depending on how much bone that they have to work with, and the fact that there is a lot of hardware in that leg now. However, I'd be cautious about letting him fire up those afterburners ;-)

Agreed. The first time they turn him out will be a heart-in-the-throat moment for everyone. He will want to go, after being cooped up so long. And everyone will be praying to see if it holds. They may want to hold off on giving him big spaces to move in, but eventually they're gonna have to risk it, he can't grow old in that stall, he's still gonna be a young horse.
