Jen, LOTS of people have success with this surgery. They're back at work full time and out living their lives, so you won't hear much from them here on the board. MOST people have a successful outcome with this surgery.
Some people do need to eventually have their hardware out, but many people just keep it in with no problems whatsoever. I had one piece of mine out from my last fusion, but all the rest is still in there and we have no plans to ever take it out.
If you need this surgery, don't let us scare you off from it. It is a big surgery with a long recovery time, but if it gives you the relief that it should, it will be worth every second! I don't regret my surgeries at all, and if I had to go back and make the decisions again, I would definitely still have them.
If you have specific questions, we'll try to help.
Take care,
Emily
