My 12 vertebral fusion done back in March 2012, is not fusing yet. What are the chances that by 1 year post op it will be fused? I had scoliosis reconstruction and instrumentation done. I do not smoke, not obese, not diabetic and have not taken any NSAID's since before surgery and I exercise regularly including physical therapy. However, I am 43 years old and not only had the aggressive scoliosis but also degenerative disc disease and work on a Labor and Delivery unit. (Hard work.) IF anyone has gone through something similar or have any advice to shoot my way I am game. Thanks.
