Well I also had it done, C4 C5 , was still on the Altanta Fire Dept. then, its been way over 10 yrs. I have had great success. It got so bad that I could not draw a bow at all, lol, guess that is when I decided to get it done! Only stayed off work for 3 mths. But on the first run that my ladder truck had upon returning for duty we had a WRECK! Guess I should have stayed off work a little longer, but no harm was done. Hope this helps, its always good to hear from people that have had that type surgery.
