To start backwards, microdisectomies can leave the disk weakened and more prone to herniate again. I don't know if that's why your local folks are refusing to discuss them, though a blanket refusal with no discussion sounds more like a bunch of closed-minded docs instead of a well-thought-out reasoning for the refusal.

Second, 5-6 ADRs a year for your local hospital is simply not enough for them to retain competence, IMHO. If you were desperate and needed immediate treatment, they'd be an option. It sounds like you're doing well enough to seek a surgeon who does ADR regularly. It doesn't have to be hundreds per year but at least frequently enough that there's a feeling of maintaining competence.

While I tend to agree with you about the M6, I'd approach it differently: find a surgeon who you can trust to be competent in their ADR skills, then discuss which model of ADR they feel would work for you. I'd avoid the M6 but I wouldn't allow a incompetent surgeon to install a non-M6 over a competent surgeon who only uses M6s.
