I was released for light work in March [meaning desk work as I am a lawyer] after my first foray with the fusion 6 January 2006. I still wore my brace, inspiring a few chuckles, but then I am known as one with a sense of humor while also hard pushing to get back into the arena. So, with short days, a smile to have returned, and such.... I regained my work, first taking a flight to catch up on cases I was handling in May thereafter.
Now, for other reasons that is not the end of my story, but I felt GOOD at the time to have resumed the office while not letting IT beat me. For you I pray the resumption of desk work will be both allowed and rewarding after a successful procedure if you go ahead.
I did have residual numbness below the knees which persists to this day, so the control for belly dancing I certainly would not have, along with the less flexible body due to the fusion. That is a goal you will need to discuss with your surgeon.
May all be well for you,
