So what has baffled me for a long time is that in a fantastical world with insane technological advances, magicians who can rewrite reality, and people who can reform matter by thinking too hard at it... Barbara Gordon can't get her spine fixed. While I'm of the opinion that Babs is more interesting as Oracle, the info-hacker extraordinaire, on top of the fact that she can absolutely hold her own despite being wheelchair bound... it doesn't really follow internal DC logic that someone wouldn't have figured out a way to make our favorite red-headed crusader of the night (sorry Kate) all walkable.
