You don't have a "deformed spine" -- the spinal cord was being "deformed" or pushed in by a large herniated disc. So your spine itself is NOT DEFORMED. The spine is the bony part. The cord is not.
What is done about it would be up to any surgeon. I would hope that you get SEVERAL different opinions about this. Don't take the word of one surgeon. You MUST get at least 3 opinions from different Neurosurgeons as to what needs to be done.
God bless and please take care. Hugs, Lee
