Hi, my son nate has an ankle/foot contracture that happened during the time he was paralyzed. Nothing was done to prevent it but thats another story.
Anyway, I took him to a very good Orthopedic surgeon to see what can be done.
He told me he would normally operate to fix that but putting a GBS patient under is not advised and could cause a total relapse.
He sent us to a place to make him an AFO to gradually stretch his foot and ankle back into the right position.
They told me it may take a couple of years to correct but they believe it will work. His ankle has already moved some.
There must be something that can be done with the hips. Don’t let them just write you off that way.
I would get more opinions until someone says they can help you.
