Adolescent idiopathic scoliosis is highly prevalent, accounting for approximately 2% to 3% of adolescents and 80% of all scoliosis.The earliest brace was the “metal armor” invented by Ambrose Pare (1510-1590) in the 16th century.A number of prospective, long-term follow-up studies were reported in the early 1990s. In the early 1990s, a number of prospective studies with long-term follow-up were reported, and the results showed that the brace-treated group was significantly better than the natural course group. Biomechanical studies in the last decade have shown that early bracing can reduce the unbalanced load on the cartilage endplates of scoliotic deformities, alleviate the unbalanced growth, and have a long-term effect on deformity control, thus confirming the exact therapeutic effect of bracing on mild to moderate adolescent idiopathic scoliosis. Therefore, early scoliosis treatment with braces can control the progression of scoliosis deformity and maintain trunk balance. Who is suitable for brace treatment? I. Who is suitable for brace treatment? However, brace treatment should be chosen with caution in the following cases: as seen in the above figure, scoliosis angle >20? or progression of 5°/year is the best time to choose brace treatment; Risser’s sign represents the patient’s bone growth potential, usually women can take menstruation as a sign, and menstruation can be instructed by the doctor to remove the brace for more than 2 years. 1, the growth and development of mature, mental anomalies, patients and parents do not cooperate; 2, severe thoracic kyphosis, excessive obesity, sensory abnormalities; 3, bone growth has stopped. Second, the commonly used therapeutic support? 1.Boston brace is mainly used for correcting lumbar or thoracic lumbar curvature, but the effect is not good for some very large angle of thoracic curvature correction. The advantage of this kind of brace is that it can be completely hidden under the clothes and does not affect the patient’s appearance. 2.Milwaukee brace Milwaukee brace belongs to the typical cervicothoracolumbosacral joint brace, which is mainly used for severe thoracic bending, and treats severe lateral bending deformity that cannot be corrected by Boston brace. 3.Other Charleston flexion brace is used at night; SpineCor soft body brace adopts strong elastic strap, which is suitable for mild and simple scoliosis patients; CrassCheneau brace can be dynamically corrected; Halo brace is stronger but more traumatic; in addition, there are also TriaC brace, SPoRT brace and so on. Third, the common considerations of the brace treatment? 1, the main basis for the choice of support: (1) patient compliance; (2) support brought about by the psychosocial factors; (3) on daily life, such as eating, toileting impact; (4) whether to lead to significant pain in patients. 2, support the use of the attention of the key points: (1) support wear to tighten the body. The brace must fit, the belt must be tightened, the orthopedic effect is good, the movement will be comfortable. (2) support wear time should be sufficient. Generally not less than 23 hours a day, 1 hour reserved for bathing, rehabilitation exercise and other activities. (3) Adjust and remake the brace in time. If the child’s height and weight change significantly, it should be reviewed in time, and the brace should be adjusted according to the need to achieve a better therapeutic effect. (4) How often should the review be done routinely? The review interval is related to the growth rate of the child’s height, and should be reviewed once every 3 months during the peak period. However, in order to minimize radiation exposure, it is recommended that only orthopantomograms be taken, and attention should be paid to covering the neck, perineum, and breasts. (5) Take off the brace a few hours in advance of the review: Usually the brace is taken off the night before the radiograph, usually 12 hours before the radiograph. However, recently, some people propose to take off the brace at the end of a complete wearing cycle, for example, the doctor’s advice requires you to wear the brace for more than 20 hours, 24-20=4, then you will take off the brace for 4 hours to take a picture.
