There are many causes of scoliosis and retrognathism of the spine, such as neuromuscular disease, neurofibroma, neurofibromatosis, vertebral tuberculosis, cerebral palsy, Marfan’s syndrome, etc. Congenital scoliosis due to congenital spinal developmental malformations is one of the major types and accounts for a significant proportion. Congenital scoliosis is divided into three main types: 1, poorly formed vertebral body, such as hemivertebral deformity A complete hemivertebral body in addition to half a vertebral body, there are epiphyses above and below, and separate vertebral plate and arch root, there are also hemivertebral body above or below the lack of epiphysis and adjacent vertebral body into one. 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. Some hemivertebrae are small, even a quarter of the size of a normal vertebrae, but they can cause extremely serious scoliosis and kyphosis and must be treated with surgery as soon as possible. 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 middle hemivertebrae in the thoracic spine 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. 2, vertebral subsegmentation incomplete vertebral subsegmentation is not a fusion between more than two vertebral bodies together, near the fusion of the vertebral body side (called the bone bridge) growth and development disorders, while the other side continues to develop, thus causing scoliosis. The bridge is located behind or on both sides of the vertebral body, and anterior kyphosis may occur. 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 presence 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 the thoracic deformity, cardiopulmonary dysfunction, poor physical fitness, and therefore bring difficulties, difficulties and risks to the surgical treatment.
