Goat wroteYeah, I'm sure broken backs take a little more mending than having some fellow punch you then hang you up for a bit. Still, I'm not a doctor, what do I know...
Although, Batman's back was broken in the comics by Bane, it wasn't necessarily broken in the film. Displaced vertebrae was all that was mentioned.
And yeah, I could see DW's point, but Bane's quick disposal was a way of getting rid of him without Batman killing him. Because I don't know how Batman could restrain him. And as for Wayne getting back to Gotham easily, he was on the lam for the a few years in Batman Begins, I'm sure he could figure out a way to stow himself in a Wayne Enterprises plane, but I guess how he got through the blockade is a little tricky...
