I had surgery December 2005 after a bad fall. I had 2 levels fused with donor bone: C4/C5 & C5/C6.
After the surgery, I never did experience a hoarse voice, sore throat or any incision pain whatsoever.
The only pain I was left with was the horrendous nerve pain down my left arm which I had hoped would miraculously disappear after the surgery. I am quite pleased that it did subside after a few weeks and now the I only have a little itchy/tingling remaining that only is a minor annoyance.
I was back at work WAY earlier than I should have been, though, yet to this day haven't felt anything wrong with my neck. I love my surgeon, he was awesome!
My husband had a single level ACDF as well in Jan 2005 (same surgeon) and he didn't have any problems at all and has never looked back.
So there's my happy cervical fusion story.
Now I just need to get my lumbar spine in order.
