Causes of cervical spondylosis
Causes of cervical spondylosis
1. Degenerative changes of the cervical spine
Cervical degenerative changes are the main cause of cervical spondylosis. The degeneration of the intervertebral disc is particularly important. It is the first factor in the structural degeneration of the cervical vertebrae, and thus evolves a series of pathological anatomy and pathophysiological changes of cervical spondylosis. 1 intervertebral disc degeneration; 2 ligament - intervertebral disc space and hematoma formation; 3 vertebral body edge spur formation; 4 cervical spine degeneration; 5 spinal canal diameter and volume reduction.
2. Developmental cervical spinal stenosis
In recent years, it has been clarified that the inner diameter of the cervical spinal canal, especially the sagittal diameter, is not only related to the occurrence and development of cervical spondylosis, but also has a close relationship with the diagnosis, treatment, surgical method selection and prognosis of cervical spondylosis. Some people have severe degeneration of the cervical vertebrae, and the epiphyseal hyperplasia is obvious, but it is not onset. The main reason is that the sagittal diameter of the cervical spinal canal is wide, and there is a large compensation gap in the spinal canal. In some patients, cervical degeneration is not very serious, but the symptoms appear early and more serious.
3. Chronic strain
Chronic strain refers to various over-limit activities that exceed the maximum range of normal physiological activities or the local tolerable time. Because it is different from obvious trauma or accidents in life and work, it is easy to be neglected, but it has a direct relationship with the occurrence, development, treatment and prognosis of cervical spondylosis. The occurrence and causes of such strain mainly come from the following three situations:
(1) Poor sleepy sleeping position due to its long duration and inability to adjust in time when the brain is at rest will inevitably lead to imbalance of paraspinal muscles, ligaments and joints.
(2) Improper working posture A large number of statistical materials indicate that some workloads are not large and the intensity is not high, but in sitting position, especially the low-head workers have a high incidence of cervical spondylosis, including domestic workers, embroidered women workers, office workers, Typing scribes, assembly workers on the instrument line, and so on.
(3) Inappropriate physical exercise Normal physical exercise contributes to health, but activities or sports that exceed the neck tolerance, such as the body upside down or somersaults with the head and neck as the load-bearing support points, can increase the load on the cervical spine. Especially in the absence of proper guidance.
4. Congenital malformations of the cervical spine
When performing a health check on a normal human cervical vertebra or a comparative study, it is often found that there are various abnormalities in the cervical spine, and the bones are obviously deformed by about 5%.
