Broken fibula and tibia - teen - how long in hospital?

I broke my leg,ankle, and foot (so both those bones plus more) and was able to leave the same day. In most cases you are able to leave the same day the only reason they would keep you is if surgery is needed immediately and if that's the case probably only a night or two or if they suspect internal bleeding and that could be up to a week and also if they suspect internal bleeding it was probably bad enough surgery was needed.
