I have had 2 posterior surgeries at C6-7, for sever rupture. And then anterior to remove and fusion. I can tell you, I would take anterior any day. The recovery it worse the first 6 weeks, in that you have to wear a rigid cervical collar, but the neck pain that I have from the other 2 surgeries are all day every day.
I had a cervical fusion c5/c6 10 years ago. It was anterior.
My understanding is that access is easier this way.
Dear Ev:
Sorry to hear about your friend. Many technics are neurosurgeon specific, some are lesion specific, and some we just don't know why someone chooses a particular procedure. I really can't tell you much without knowing more about your friend. As far as risk, pain, and recovery time these things are lesion specific and surgeon specific. I would not tell you that one procedure is any more risky than the other. Again, this depends on the extent and the type of lesion present. Sorry, I am not much help.
Sincerely,
CCF Neuro MD
