One very important point about conservative treatment is what is the effectiveness of conservative treatment? And what are the criteria for evaluating its efficacy? In fact, the treatment of scoliosis by bracing is one of the many conservative treatments that most experts at home and abroad consider to be potentially effective. The purpose of bracing is to control the progression of the deformity, not to treat the scoliotic spine! In other words, when she wears the brace for a certain amount of time, and after she removes the brace and relaxes her torso for a period of time, her spine remains at the same level of scoliosis as before the brace treatment, then such brace treatment is considered to be 100% effective. In other words, brace therapy can only control or slow down the progression of scoliosis in most patients with scoliosis, but it cannot straighten an already diseased and curved spine again! Perhaps then you can understand the true meaning of brace therapy. For a patient with scoliosis treated with a brace, one must not focus only on the spinal radiographs taken while wearing the brace… that is an illusion! During the follow-up observation of the brace treatment, we usually ask the parents to remove the brace from the child the night before the next follow-up visit, let her relax and sleep, and then go back to the hospital the next day to take a full-length frontal and lateral radiograph of the spine, and then, compare it with the radiographs taken before the treatment or at the previous follow-up visit. In cases where the treatment is effective, the Cobb angle can be controlled (no or little growth) during the brace wearing period. If an increase in scoliosis is still found during the brace application period, then the brace treatment should be judged as ineffective or inefficient, if one can exclude the case of lax brace wearing. At this point, I am afraid that it is no longer a matter of insisting on brace treatment, but to realistically consider elective surgical correction. Although the brace treatment is a method of conservative treatment that has received more affirmation, it also has its own disadvantages, one of which is the restriction on the development of the thorax, a patient who wears a brace for a long time is likely to have restricted development of the thorax, girls appear flat chest, etc. If the brace is removed in time, these developments can still be improved, but if it is worn for too long, the small thorax (expressed as a lack of lung breathing volume) and flat chest posture will be It is difficult to correct. A girl’s menstruation is a landmark marker in chiropractic care, and her presence often indicates that the spine is in its final stages of development. Therefore, the timing control of brace treatment is strongly related to the onset of menstruation. Generally, 1 year after the appearance of regular menstruation, the ability of the spine to continue growing is close to zero, at which point the brace can be removed.
