I had 2 stage surgery in jan13,
The first op, anterior release was to loosen the spine, they went in through my right side removed 4 discs & ribs to loosen the curve, and then a week later they put me back together so to speak putting the metalwork in.
Sound worse than it worse, it was tough, but sooo worth it!!!
My spine isn't totally straight as you can see from my profile pic, but I also had a costoplasty during the 1st stage so my rib hump is virtually gone thank god!
I'm not perfect but I am a million times better than I was, and most importantly I'm fixed and the happiest I've ever been
Good luck with you journey
