I had anterior scoliosis surgery in 1999 to correct a 50 degree curvature. Now I have a ten-inch rod in my back, with a spine that fused perfectly long ago. Everything went fine, and I have experienced minimal discomfort since then. I am healthy, athletic and active. These are the only activities I have been hesitant to try, and I can't ask my doctor because he treated me at a children's hospital. I'm pretty sure they would ask questions about a 27 year old making an appointment for herself!
