Oh, I'm really sorry that happened to your mom! My mom broke her hip a few years ago and had to have a partial replacement, too. Only, in her case, she says she didn't fall; she just got down on the floor (for some reason) and couldn't get back up. It's going to take a while for her to get back to "normal," but things will get better. She'll need to go for rehab. Thinking positive thoughts for you and her.
