Scoliosis is most common in children and adolescents, and the incidence rate is about 2-3%. Early detection and early treatment is the best way to prevent the aggravation of the deformity. Most of the scoliosis children are found in the census, and some of them are found by parents by chance. Therefore, parents should pay special attention to whether the child’s shoulders are symmetrical, whether the scapulae are equal in height, whether the thorax is symmetrical, whether the pelvis is tilted, whether the hips are equal in height, and whether the lower limbs are equal in length.
