My son was diagnosed with scoliosis when he was 14 (about 1 year ago). He had a double curve each more than 40 degrees. He wore a brace for almost a year but it didn't really help. We didn't try a chiropractor because the literature we read and our doctor said it wouldn't work. Our son eventually had a spinal fusion and instrumentation in April this year, and the operation went very well. Recovery was quick and fairly comfortable. So if your daughter really requires surgery, you don't have to worry too much. Just make sure that you have a good doctor, and that your daughter understands the process. I suggest you and your daughter visit www.iscoliosis.com; we found it very informative and reassuring. Good luck to you and your daughter.
