I had laminectomy on C7 in 06, and 2 level ACDF on C5-C7 in 08. Now a new surgeon (this one highly rec ortho guy) says the fusion is failing at C6-C7 and I have a lesion at C7-T1, and a rupture at C4-5. Wants to do a 4 level fusion from the back. Anybody here been through that? Experiences you've had?
