Are you being told that only one or both discs need an ADR? From your description it sounds like both the L3/4 and L5/S1 are pain generators. But it's not clear.

I'm curious because the Kineflex/Charite study is only for one level. You should not be allowed into that study if you need multiple levels unless they are expanding the study. However, I just received an email from the Plano facility that there is no multi level arm of the study.

So I guess my point is that you might want to get some clarification on whether you have 1 or 2 disc problems, and if you have 2 levels of problems, why are they referring you to the study? You wouldn't want to go through surgery when only half of your problems are addressed.

you've probably already discussed all this with your surgeon but just in case....it's something to think about.
