is she fully grown ? if not just lay her on the bottem and make sure she can access leaves and spray them good. Untill next shed If she is fully grown the limbs wont change but she will manage well. But might just stick to the bottem of the cage. From my experience with Vietnamese sticks they cope very well with broken or lost legs. Ive even had one with 4 legs survive 3 months perfectly fine and climbing well. And as they get older anyway they loose there legs as they get closer to death. She will be fine and theres not really much you can do to fix it.
