Let's just agree to disagree. You think it's a valid reason that she refuses prosthesis and "[dreams] of the medical breakthroughs that might someday restore" her spine, and I like to mock Oracle for not researching the Brainiac virus that was working to repair her spine. Your reasoning is probably more sound in the eyes of creators; Oracle is a 20 year old character created before nanotechnology became popular, it's hardly fair to compare her to new, modern characters who use it.
