Wendy... I'm looking foward to hearing what your doc has to say. Dale's point is well taken, that the recommendation for or against ADR often has to do with many factors, including comfort level of the surgeon, what his/her hospital will allow, how different procedures are reimbursed, etc...
As for no ADR w/less than 50% disc height... that sounds like a hard and fast rule in a place where each case is different. Here are my wife's pre and post-op pics... she's only 7 weeks out of 2-level ADR, but the severe prior disc collapse was no issue.
