those kind of injuries, i doubt he'd be able to leave the hospital in a few days..
I had 2 compression fractures in my vertebrae, a shattered right elbow, compound fracture left arm, each wrist has 6-7 pins in it, 2 external pins on 2 fingers, a broken pelvis, collapsed lung, broken jaw and dislocated TMJ's. I was walking 19 days after the accident, and I was sent home 24 days after the accident.
He'll be in there based only upon his injuries to his spine. Because they only list fractures I'm assuming it's compression fractures, depending on severity, 9/10 times you'll be sent home in a week or so with an upper torso brace of some sort and told to take it easy for the next 3-5 months.
Regardless glad to hear he's doing okay and made it out alive!
