Glad it went so well!
I've heard good things about ADR (artificial disc replacement). SO much better than fusion, IMHO. Even if not for getting your walking back, Earl, to keep other sx from happening. Who needs more nerve damage?
You've been around the block enough I shouldn't have to say this, but do your homework. ADR is still pretty new. Some docs have more experience than others, and I want to see you end up with the best you can find. Maybe check in with the Brain Talk bunch - a lot of ADR vets there, you know?
