Has anyone asked their doctor how long it takes for bone spurs to grow? Or how early after an ACDF a person can start having problems with Arthritis? I have heard some doctors say years... But I really don't think it takes that long. After having an ACDF isn't fusion growth of bone?? I have also read on these lists, where someone had a bone spur cleaned up, for it only to come back. How fast do they come back? I am sure they are not years....Are they?
