Hemivertebral deformity

Introduction to hemivertebra deformity This is the most common type of vertebral deformity, easy to single, or multiple. Vertebral malformations are more common in the thoracic vertebrae, and the lumbar segments can also be encountered. Also known as the semi-spinal deformity. In fact, such deformities are not limited to vertebral bodies, so the semi-vertebral body is not accurate, although this title is popular in the domestic orthopedic community. According to the clinical symptoms of the disease, depending on the location of the deformity, the following spinal deformities can be caused: scoliosis, kyphosis, scoliosis and rotational deformity. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific people Mode of infection: non-infectious Complications: scoliosis

Cause of hemivertebra malformation

Cause (55%):

The cause of the disease is still unclear. Due to the degree and location of the semi-vertebral deformity, there may be various clinical symptoms. In addition to the deformity of the cervical vertebrae and the limitation of cervical vertebrae, spinal neurological symptoms including pyramidal tract signs and dyskinesia numbness and dysfunction may occur.

Prevention of hemivertebra deformity

Life restraint pays attention to rest, work and rest, life is orderly, and maintaining an optimistic, positive and upward attitude towards life is of great help in preventing diseases. Do the regularity of tea and rice, live daily, not overworked, open-minded, and develop good habits.

Hemi-vertebral malformation complications Complications scoliosis

Can be complicated by scoliosis, kyphosis deformity, severe deformity, can be combined with heart, pulmonary insufficiency.

1. Clinical symptoms The different parts of the visual deformity may cause the following spinal deformities:

(1) Scoliosis: due to single or multiple vertebral deformities.

(2) kyphosis deformity: seen in the posterior half vertebral deformity.

(3) Scoliosis and rotational deformity: If the gravity of the upper part of the body is unbalanced, the lateral bending deformity with obvious rotation may be gradually formed during the development, accompanied by signs such as thoracic deformation, and the hemivertebra. Malformations are also prone to occur with posterior vertebral deformities.

(4) Height growth limitation: it is affected by multiple people.

2. Classification Nasca has divided vertebral deformities into the following six types:

(1) Simple remaining vertebral body: that is, a circular or oval bone block remains between adjacent vertebral segments, which is easy to fuse with adjacent vertebral bodies.

(2) Simple wedge-shaped semi-vertebral body: refers to the appearance of a wedge shape on the X-ray positive position.

(3) multiple vertebral bodies: exponential joints.

(4) multiple vertebral body combined with one side fusion: more common in the thoracic vertebrae.

(5) Balanced vertebral body: that is, the deformity of 2 or more segments is bilaterally symmetrical, so that the deformities cancel each other out, and the shape of the lateral bending is not caused by the shortening of the trunk.

(6) Posterior hemivertebra: refers to the development of the osteogenesis center behind the vertebral body and the central osteogenesis center is not developed, so that the vertebral body forms a wedge-shaped deformity appearance from the lateral view.

Examination of hemivertebra deformity

X-ray examination can show deformed vertebral body and CT or MRI can be performed if necessary. Magnetic resonance imaging (MRI) has been applied to the imaging diagnosis of various systems throughout the body. The best effect is the brain, its spinal cord, large blood vessels, joint bones, soft tissues and pelvis. Cardiovascular disease can not only observe the anatomical changes of each chamber, large blood vessels and valves, but also can be used for ventricular analysis, qualitative and semi-quantitative diagnosis, can be used as multiple cut charts, high spatial resolution, showing the whole heart and lesions And its relationship with surrounding structures, superior to other X-ray imaging, two-dimensional ultrasound, radionuclide and CT examination. Coronal, sagittal and cross-sectional images can be used in the diagnosis of cerebrospinal lesions.

Diagnosis and diagnosis of hemivertebra deformity

Mainly based on clinical features and X-ray film, if necessary, CT or MRI examination, but at the same time should be comprehensive judgment of the patient's general condition and complications. According to the clinical symptoms of the disease, depending on the location of the deformity, the following spinal deformities can be caused: scoliosis, kyphosis, scoliosis and rotational deformity.
