I had posterior fusion from C-3 to C-7 with 2 rods placed in the back of my neck it is an very painful operation as the surgeon is cutting through your neck muscles.The surgeon who did my operation placed the screws at C-3,C-4 into the facet joints and C-3,C-4 didn't fuse causing a lot of neck pain.I was very lucky to find a surgeon who did an anterior fusion at C-3,C-4 with a stand alone cage which stopped the movement in my neck and it fused there.I had no pain from that operation and went home the next day I did have a sore throat for about 2 weeks.If I had found this surgeon before I would have been better off.
