Background

Adolescent Idiopathic Scoliosis (AIS) refers to a scoliosis of spinal structure occurring during adolescent without other organic diseases, and is the most common scoliosis. The AIS patient is greater than 10 at the side bend angle of coronal plane upside, along with the increase of the side bend angle and the appearance deformity of backbone, thorax that the quick progress of nature course of disease influences heart, lung function, causes serious harm to infant physical and mental health, brings serious burden simultaneously for infant family and society.

The treatment of AIS is diverse and can be summarized as non-operative treatment and operative treatment. The non-operative treatment is suitable for the children patients with early diagnosis, light degree and small risk of curve progression. Patients with AIS have Cobb's angle more than 40 deg. and immature skeleton development, patients with ineffective conservative treatment (half-year medial curvature progress more than 5 deg.), patients with chest and waist kyphosis or lumbar kyphosis with obvious appearance deformity, and patients with waist and back pain.

Scoliosis surgery is the most severe surgery for spinal injuries. A common procedure is to fuse multiple segments of vertebrae together with multiple screws, resulting in a permanent loss of mobility of the spine.

In addition, the height of the scoliosis orthopedic device is adjusted by limiting and fixing the upper shell part, the lower shell part and the orthopedic structure, secondary operation is not needed, and the adjusted height is controllable and quantifiable, so that the scoliosis orthopedic device can gradually realize the orthopedic of the scoliosis spine.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
