Hello Barbara and Welcome -

I am sorry to hear you and your daughter are struggling with this condition. I found a few discussions and resources that may be helpful -

Can't supinate left wrist
Ulna and radius fused together - Many responses with good real life experience.

As Dr. Benaroch mentioned a university medical center may have a hand/upper extremity specialist that can follow and advise you on possible treatment and outcomes.

Please let us know if this is helpful and keep us posted,
