Regarding congenital hemivertebral scoliosis, which is generally not segmented and develops slowly, my opinion: after skeletal stereotypes, no progress in the thoracic segment less than 45 degrees of follow-up observation, does not (or a small amount) affect the appearance, does not affect trunk balance, does not affect spinal function, can be done without surgery. In the lumbar segment 35 to 45 degrees scoliosis, rotation of more than 2 degrees, I tend to do in recent years, because for my surgery to treat a large number of adults with painful scoliosis, mainly due to scoliosis caused by disc degeneration, spinal stenosis, surgery in old age, more difficult Complications more, so more than 30 degrees scoliosis, I tend to do when young. If you can send me the x-ray photos, I can give you a clearer answer.
