I wouldn't jump him under saddle at all until after his 5th birthday, and then keep things low and not too often until close to 6yrs old. All of the bones in his body will be closed and done growing between 5-6 years old.
He's perfectly healthy. He's my trainer's horse and they are very careful with breaking horses and he's been jumping for a couple months. They take things a lot slower than other people do as well. I've never heard of something like that, but he's already jumping under saddle. Not a lot, obviously, just once every couple weeks. He's shown as well I believe.
