Hi there ! In my opinion its nothing to worry about until there is a major bone damage (it's rare), I once had a hamster which used to jump from several things as he was a curious one but he never had any injury or something. Hamsters don't have a good eyesight so they sometimes tend to jump even unintentionally.
Pls keep an eye on her ,specially check if there is bleeding in leg. Though it wont happen at all ,so dont worry��
