It sounds like a spinal injury to me. She might survive, partially paralyzed, if her innards still function normally. Quality of life would depend on how well she does mooving around on her front half.

In your place I 'd make her comfortable, offer water and a bit of cut up nightcrawler.(take the fight out of the worms.) Watch for defecation and consider options for euthanasia should recovery prospects look bad.)
If she does eat and pool and get around her enclosure adequately, she will probably still require assistance to live long. (Protection and shed assists on paralyzed area.)
