After almost 2 yrs. I'm back on this forum. I had a C5/C6 fusion 12/2007, and it was a piece of cake. As expected C4 & C7 are now getting nasty. I was under the impression that in the U.S. artificial disks weren't FDA approved? I guess my question is, if they are, can I do this when I already have one fusion? I am doing therapy, then injections, apparently to smooth the way for surgery & my insurance co. Thanks.
