I am sorry to hear you were denied at Shriner's --I have heard of a few kids with complex medical problems being turned away. Curious though, which Shriner's was that?
I would still suggest you get in contact with Janet Cerrone, the PA for spine surgery in Philadelphia. They see all sorts of very complex spine cases, so perhaps they can help your daughter. Janet is also an extremely nice person. Her e-mail is firstname.lastname@example.org
