The invention relates to an orthopedic device in vitro for human adolescent scoliosis, and particularly relates to an adjustable combined scoliosis support. The adjustable combined scoliosis support is composed of a shoulder ring, a pelvic ring, an elastic plate and a support plate, the vertically arranged elastic plate detachably connects the rear part of the shoulder ring with the rear part of the pelvic ring, the vertically arranged support plate detachably connects the front part of the shoulder ring with the front part of the pelvic ring, the elastic plate can ensure continuous pressure on a top vertebra area, dynamic and continuous pressure orthopedics is achieved, and the orthopedic effect is improved; and shapes and sizes of the shoulder ring, the pelvic ring, the support plate andthe elastic plate are all obtained from data scanned by CT of a patient, 3D printed and formed for one time according to body data of the patient. The adjustable combined scoliosis support only touches key parts of a body, a covering area of a trunk is greatly reduced, the permeability is improved, the size and the area of the support are reduced, the support is easily covered by clothes on the outside, is comfortable, attractive and efficient, is easy to be accepted and cooperatively used by a child patient, and easy to assemble and wear, and the ability to correct scoliosis is improved.
