The only option I can think of would be to see her in the hospital or give her your number through a note in her office and tell her to call or text you, if you leave her a note she may not remember you unless you write something in the note that would make her remember you, like something you said or did, maybe also mentioning that you came in to check your ribs. Since you probably don't wanna be another random patient that hit on her to also be the first one ever to come and surprise her and possibly bother her when shes working in the emergency room instead you should probably write her a note containing what I mentioned above seeing how it's probably a lot less intrusive and not stalker-like behavior and gives her the option of calling you, although there's that possibility of not hearing from her, I think it's your best shot.
Good Luck
