Adjacent disc herniation

[dshobbies]

Mark and all,

While reading the post on preemptive ADR on top of fusion to head off future problems, I remember reading a study that suggested ADRs also negatively affect adjacent discs over a longer period of time. With the drugs I'm taking and unable to remember where I left my feet , I couldn't tell you when or where I read this but I believe I did briefly discuss it with Mark.

If the above is true, then putting an ADR into an overwise healthy disc would/might be fruitless. I think most of us believed that ADRs stabalized our spines, taking all excess pressure off of adjacent segments. Is this or isn't this true?

Anyone?
