Haven't jumped since. But he's a dressage horse so I decided its not really necessary. Once horse is fully back in work and has been conditioned properly no reason not to start jumping as normal. The good thing about a fractured splint bone is once they are healed they are actually very strong.
if you are intrested i am expecting a disc through the post of my girls x-rays before and after surgery for her splint bone surgery. i can post them on the forum if you would like to see them
