*vibes*
I know a pony who broke his leg at the age of around 4/5 (was lent out to go hunting with a little girl, girls dad got completely pi**ed at the meet and flipped the trailer on the way home!) He made a complete recovery, went out regually hunting and pony camp etc (always winning), and is still alive now in his late 30's, without any repercussions, not a single days lameness since healing.
