My DIL has more pain post fusion. With that said, I've seen her x-rays and the doctor just left a useless 2" segment sticking straight into her erector spinae. It's not attached to anything and is not bent to curve with her spine. She also has very hard trapezius muscles like I do. I suspect that these would have started hurting her eventually anyway. Her scoliosis would have also become a source of contention for her as she was near 50o and badly rotated for the amount of curvature she had. She'll eventually be a chronic pain patient, though. She actually already is. She just doesn't have insurance to go to the doctor and suffers terribly. I've seen her WAY understate her pain levels at Dr. appointments compared to how she is at home. It's one of those cases where you're darned if you do and darned if you don't.
