Overview This is the most common of the vertebral deformities and is easily solitary or multiple. Vertebral deformities are common in the thoracic spine and can also be encountered in the lumbar segment. Symptoms 1. Depending on the location of the deformity, the following spinal deformities can be caused: 1. scoliosis: due to single or multiple hemivertebral deformities. 2. 2, kyphosis: seen in posterior hemivertebral deformities. 3, scoliosis and rotation deformity: severe scoliosis, if the upper part of the torso gravity imbalance, can gradually form during the development process with obvious rotation of the scoliosis deformity, and accompanied by thoracic deformation and other signs. Hemivertebral deformity with posterior hemivertebral deformity is also likely to occur. 4, height growth restriction: the impact is greater in multiple cases. Nasca has divided the vertebral deformity into the following six types: 1, simple remaining hemivertebral body: that is, a round or oval bone block remains between the two adjacent vertebral segments, easily fused with the adjacent vertebral body. 2, simple wedge-shaped hemivertebral body: refers to the wedge-shaped appearance of the vertebral body on the X-ray orthopantomograph. 3.Multiple hemivertebral bodies: the index nodes are consecutive. 4.Multiple hemivertebrae combined with fusion on one side: mostly seen in the thoracic spine. 5, balanced hemivertebral body: that is, 2 or more sections of the deformity left and right symmetrical, so that the deformity offset each other, in addition to trunk shortening, and does not cause obvious scoliosis appearance. 6, posterior hemivertebral body: refers to the development of the posterior osteogenic center of the vertebral body while the central osteogenic center does not develop, so that the vertebral body from the side view to form a wedge-shaped deformity appearance. Mainly based on clinical features and X-ray plain film, if necessary, CT or MRI examination, etc.. However, the patient’s general condition and the presence of complications should also be fully determined. X-ray features of the hemivertebral body: at birth, the hemivertebral body is smaller than the normal vertebral body, round or oval, and biased to the midline side. With gradual development and the influence of weight bearing, this round or oval hemivertebral body gradually becomes wedge-shaped. The hemivertebrae may occur singly or involve several vertebrae, forming a scoliosis deformity. Complications It can be complicated by scoliosis and kyphoscoliosis deformity. In severe deformities, cardiac and pulmonary insufficiency may be a complication. Treatment Depending on the characteristics of the deformity and the degree of abnormal spine development caused by it, corresponding treatment measures can be applied. 1. Severe scoliosis with or without rotation and deformity should be treated surgically as scoliosis. 2.Severe hunchback deformity has already been established and affects the basic life can be treated by osteotomy. 3, adolescent cases In order to avoid or slow down the occurrence and development of spinal deformity, bone graft fusion can be performed on one to several segments of the convex side of the spine to stop the growth of the segment. However, in order to avoid overcorrection, too much fusion should not be done at the beginning, and close observation is needed. 4, mild deformity can be supplemented with a brace, and strengthen the back muscle exercise. 5.Pay attention to the prevention and treatment of various complications Especially in severe spinal deformities, most of them are accompanied by cardiopulmonary insufficiency and should be treated comprehensively.
