I've had several "hippy babies" do extremely well, even when surgery was impossible. Jazz has a dislocated him to this day; kitties usually form a "false joint" which does nicely. In fact, sometimes vets use this to advantage by cutting the "ball" of the hip off surgically (FHO) and letting the body do its thing.

I would DEFINITELY crate her in a crate big enough for food, water, a soft bed, and a small litterbox. Beauty, was was crushed, came out a little at a time after several weeks, as she felt a little better. Jumping was the last skill to come back for all of them, and a little bunny hopping, especially on stairs is typical, too.

Pain meds would be useful, until the worst is over.

Good luck; she'll probably be fine.
