In May 2011, I had a revision neck surgery in which the Neurosurgeon removed failed Pro Discs from C5/6 and C6/7 (implanted in March 2009) and then did a three level fusion from C4 - C7. He also used both allograft and autograft bone. I felt okay in the beginning (I got horrible headaches after my ADR surgery) but in April of this year I began getting terrible headaches and a lot of neck pain. Since my surgeon is on a mysterious leave I was told to go to my primary care doctor, who ordered a CT scan last month. I went to see a new Neurosurgeon yesterday and was told that C5/6 and C6/7 is not fused and C4/5 is showing a little activity, but they want me to have a bone scan so they can see if it is fused. They suggested another surgery in which they will fuse from the back instead of front of my vertebrae and would insert rods from C5 - T1. (possibly C4 if it is showing no fusion)
I was wondering what the risks are if I choose not to have another surgery. Is my neck unstable if it is not fused? I'm concerned because when the surgeon removed the Pro Discs last year, he also removed some of my vertebrae to get the implants out so it wasn't an typical fusion. I am so scared to have anymore surgeries and worried that if I did, it won't work.
