At this point I just assume Batman is like Judge Dredd, after all the shit he's been through he's probably more of a bunch of cybernetic limbs and lab-grown augmented organs held together by combat drugs than a human being, so sometimes he gets to do shit like this.
Obviously DC reboots their universe every three years but if Bane breaking his spine or the Killing Joke are perpetually in the state of fuzzy canon where it never happened except it did that might make sense.
