Getting spine surgery I understand that it’s basically able to accomplish two things, let’s show this graphic and talk about these two points one of them is decompress a nerve root that is pinched, and the other one is to stabilize a painful joint, can you chime in on that doctor?.> You got it so sneak in remove a little pee that’s causing sciatica and sneak out, that’s the first, the second is where there is a painful joint arthritis or you can even say instability and that’s where you sneak in and actually stabilize that joint by little screws now this screw stay inside bone and they hold everything perfectly in place and with a new way of doing things in a better position than they were before surgery.> All right so I’m gonna ask this even though we hope this is not happening a lot but even after the surgery can patients still experience pain?.> Yes.> Yes and is it called I don’t like this but failed back surgery syndrome?.> Definitely.> Okay hopefully not too common.> So it’s very rare okay with a new technology it’s exceedingly rare, but you know when I was at Duke I saw that a lot, especially with the old classic big wide-open operations, 36 percent of patients, 36 percent of patients, have to go back to surgery within ten years,- they do it again,- again and again, and again, the new operations are closer to three percent chance so it’s still possible it’s definitely something we discussed before surgery, but now we know why this was happening so we can correct it in advance.
