Everyone familiar with Batman universe would be quite familiar with Ra's Al Ghul's Lazarus pit. Given the realism shown in the Batman movies by Nolan, for instance Bane's character and his mask. In the comics/video games Bane is portrayed along these lines with tubes to control the venom which runs into his body
In the movie he is shown as a really strong guy with a mask to subdue his pain from his previously sustained injury.
Ra's Al Ghul's pit is known to resurrect half dead people and heal people from their severe injuries, which often explains the reason why Ra's Al Ghul is immortal (That's a dialogue even quoted by Liam Neeson's Ra's Al Ghul character briefly in the scene when he talks to Bruce Wayne when he was imagining talking to him ). Given the fact Bruce Wayne gets over his broken back in a relatively few days given his age, could we assume it's equivalent to a realistic version of Ra's Al Ghul's Lazarus pit?
I would love to hear any interesting perceptions on this topic.
