I just had neck surgery(3 levels of fusion) for stenosis in the neck. Since my situation is different I cannot respond to your specific questions, but your surgeon should be able to explain this.
I am also having to delay my scoli surgery for a minimum of 6 weeks due to the neck surgery. I do know that in my case they wanted to fix the neck issue first to make my scoli surgery safer.
