I am not understanding how it is possible to have Pro-Disc L5-S1 in Nov 06, and then have end stage facets in July 07. It's hard to imagine them progressing from "OK for ADR" to "end stage" in less than a year. What was the condition of the L5-S1 facets pre-ADR?
I believe that he's referring to visible changes to the multifidus muscle. Bertagnoli once pointed it out to me on the MRI of someone who'd been bedridden for over a year.
