I know that ADR is relatively new technology (at least in the US) and is still used fairly conservatively, but I was wondering if anyone on here has had a cervical artificial disc replacement at a level adjacent to the previous fusion. I know it is a practice that is gaining steam in Europe and could possibly help prevent the seemingly endless cycle of adjacent level degeneration following cervical fusions. I am fairly young (mid-30s) with an ACDF at C5-6 about a year ago. I feel that my surgery was a success in that it accomplished what it was supposed to, but I am starting to have some new issues. I would like to remain fairly active and not be fused from top to bottom by the time I'm 40!
