1, vertebral subsegmentation incomplete. Vertebral subsegmentation is the fusion of two or more vertebrae together, and the fusion near the side of the vertebral body (called the bridge) is impaired in growth and development, while the other side continues to develop, thus causing scoliosis. Bone bridges located behind or on both sides of the vertebral body may occur anterior convexity deformity of the spine. 2, poor vertebral body formation, such as hemivertebral body deformity. In addition to a complete hemivertebral body, there are epiphyses above and below the vertebral body, and separate vertebral plates and roots, and some hemivertebral bodies lack epiphyses above or below and are integrated with adjacent vertebral bodies. The presence or absence of the epiphyseal plate and the development of the epiphyseal plate have a great relationship with the degree of scoliosis development, the better the development of the epiphyseal plate, the more serious the development of deformity. Asymmetrical development of the vertebrae on both sides, large on one side and small on the other, wedge-shaped, called cuneiform vertebrae, and a half vertebrae on each side, called butterfly vertebrae, cuneiform vertebrae or half vertebrae on both sides are different in size and can cause scoliosis. Although some hemivertebrae are small, even a quarter of the size of a normal vertebrae, they can cause extremely serious scoliosis and kyphosis and must be treated with surgery as soon as possible. You can contact me by phone for more information on how to perform surgery. For example, the upper thoracic hemivertebrae often cause the child’s shoulders to tilt unequally, the lumbar hemivertebrae in the thoracolumbar segment often cause severe scoliosis, and the lumbosacral hemivertebrae cause severe trunk tilt in addition to scoliosis deformity of the spine The thoracic hemivertebrae in the middle segment often have a left and right compensatory arc together, and a symmetrical hemivertebrae in the upper and lower left and right, causing a scoliosis in the upper and lower a left and right lateral bend. Although the above two deformities can cause two curves in the spine, the trunk as a whole is balanced, so sometimes surgery is not always necessary. 3. Mixed type. In the same child with scoliosis, there can be both convex side of the vertebral body poorly formed, such as hemivertebral body, and the existence of incomplete segmentation such as concave side of the bone bridge, and even the presence of rib fusion, the absence of a variety of deformities, this is a mixed type. This kind of spinal deformity children, mostly deformity heavy, fast development, and because of thoracic deformity, cardiopulmonary dysfunction, poor physical fitness, so that the surgical treatment brings difficulties, difficulties and risks. Therefore, parents should take their children to surgery in a timely manner and can bring them to a children’s hospital.
