I've had ACDF at c4-5 and c5-6 back in 1997. I am going back in for surgery on Sept. 16th to repair the damage that surgery has caused at the c6-7 level. Not the surgery itself but the stress it has caused on the other discs. This time I am going to have an artificial disc installed but I don't know what to expect after the surgery. Has anyone had a ADR done? I expect an easier time then the first surgery, less down (recovery) time. For those of you thinking of ACDF, think twice because of the wear and tear on the disc above and below the fusion. It seems like this is a common complication that was never told to me. Any kind words are appreciated.
