Well, she was attacked by giant evil Wonder Dog, injured and put into a coma in an issue of Teen Titans, and since then the Calculator has been all "must save daughter!".
It's still may be an interesting and unfortunate parallel to Barbara getting paralysed, given the way none of what has happened to Wendy so far has really been about her. Instead it's just been side-plots in other people's stories. (But it's still nowhere near TKJ, given that Barbara Gordon has always had greater prominence than Wendy.)
