The vast majority of scoliosis patients undergo orthopedic and fusion surgery, which is performed in a single operation with fewer complications and more definitive results. In a few patients with comorbidities or progressive disease, revision surgery may be required. So this question needs to be answered in two parts. Stereotyping usually refers to skeletal maturity. First, in skeletally mature patients, we can do a one-time posterior orthopedic implant fusion with internal fixation. Secondly, for patients who are not skeletally mature, who are not skeletally set, they usually need to have a growth bar procedure, which requires bracing every six months or eight months, which is a multiple procedure. There is also a special case, that is, the skeleton is mature, but the scoliosis is particularly severe in a small number of patients is not a one-time operation, this case needs to do traction first, and then in the operation in two times, “two times” does not mean six months or a year, but usually a few weeks apart. So whether or not the surgery is done all at once depends not only on the maturity of the bones, but also on the severity of the scoliosis.
