That's right, they're in our spine.
They're also going to fuse some of my vertebrae together, and, of course, I needed to do some research. What I found out was surprising. In 2011 over 488,000 people in the United States had their spines fused. That's more then 1300 a day. They accounted for over 3.1% of all hospital visits. Isn't that amazing! If you had asked me a month ago how many people underwent this procedure yearly, I'd have estimated about 2000. Education, isn't it wonderful.
