Prosthetics can help, but I don't think it's in Yang's personality to just casually get a new arm.

At the very least, she's definitely gonna be disarmed for a while. Maybe in a later volume she can get a custom-made one from Atlas.

Honestly, I hope she doesn't want a new arm, ever. Because we need more one-armed badasses in fictionland.
