Hi, I have scoliosis so severe that doctors had difficulty inserting 2 leads for pain control. I had a total hip replacement 2 years ago and all is well. Maybe I don't understand, but what does one have to do with the other? Why would you need spine surgery to get a new hip? I've had 2 Harrington rods & 6 screws inserted to stabilize my back, but neither helped. Last October 2020 I had a Nevro pain blocker implanted in my left flank with 2 leads to both sides of my spine. There are many settings on my remote, and I am now about 70% pain free.
