Hey Jenn, there is a saying in the ortho spine/ neurosurgery community that all you need it 100 patients to keep you practice going. I have found this to be true for several reason one being that most patients wont exercise, keep thin, eat healthy, and use appropriate biomechanics during the day, but the biggest reason is probably that with all the advances medicine has made we still cant slow down or stop the aging process. When you decompress, fuse, remove or whatever, to the spine you have to move the pressure that once was exerted there to another place, i.e disc. This then causes early degeneration and on and on and on. I'm sorry to hear your back has given you so much trouble. 16 years is a long time ago and it may be worth it to atleast look at some of the newer surgical systems present today. Just a thought.......
