My wife had a 40ft rope swing miscalculation at my cousins wedding before we were married. She also had a burst fracture of her l2. When I was in that room there must have been 15 doctors come into the room amazed that she had feeling in her feet and checking again and again, as it did not make sense with a piece of bone denting her cord. A surgery and a few years and it is as if it never happened. She is very lucky! Hoping for the same for Bryce. If it does not work out quite this well I'll hope for the very best with whatever result comes.
