Left arm was  mutilated when Ruby went ultra eyes on her. They kinda gave hint that majority of her left side was somehow damaged just with the eyepatch and the long sleeve.

Right hand had a bug implant anyway, it wasn't an actual Grimm Arm so pretty sure they could remove it. Pretty sure it had a Grimm, otherwise Ruby's SEW wouldn't have affected her. If Ruby's SEW affected maidens, then, Raven would have been affected. And the characters would immediately know she was the other maiden, especially considering she was fighting one of them
