Thanks for responding. The ortho that we saw was a highly reputable and skilled pediatric ortho. I really trust his judgement, however I do like second opinions. We have a Shriners Hospital close to us, and are thinking about getting a second opinion from them. My son has a pretty bad huncrabroadack right now. He can't sit up straight without his back hurting, and complains a lot about it when he tries to do much physical stuff. I'm not sure that watching it for a few years is the best option. Of course, the physical therapy twice a week should help. I personally think surgery might be the best option for my son, because even though he takes therapy, he's not motivated enough to do his home therapy without us nagging him and making him do it everyday. At least with the surgery, I know it would be fixed, and we wouldn't have to worry about it anymore. The older he gets, the more pronounced the huncrabroadack gets in him, so I wonder if it will only keep getting worse.
