Hi kiddo,
I am very sorry to hear about Lucy's injury.
I would also consult your vet including a possibility of amputating her bad leg.
My last foster dog came with a broken leg (left hind leg). I tried to save her leg (she didn't seem to have pain but didn't use the leg most of the time) but the vet said that she would be better off without the leg, because the nerve was damaged and it stopped growing (she seemed to be like that for quite a while but who knows she was found as a stray).
Anyway, she had a surgery 2 weeks ago and became a 3 legged dog. She got adopted and the new owner told me that she has been doing great and she even went to a dog park to play with other dogs!
I am not recommending to remove Lucy's leg but I just wanted to let you know that dogs will adjust very quickly if she ever has to loose one leg.
Hope she will be able to keep her leg and get better quickly.
