Cervical spondylosis, also known as cervical spine syndrome, is a general term for cervical osteoarthritis, proliferative cervicitis, cervical nerve root syndrome and cervical disc prolapse, which is a disorder based on degenerative pathological changes. It is a clinical syndrome with a series of dysfunctions mainly due to long-term cervical spine strain, osteophytes, or disc prolapse and ligament thickening, resulting in compression of the cervical spinal cord, nerve roots or vertebral artery. It is a syndrome of cervical disc degeneration itself and a series of secondary pathological changes, such as destabilization and loosening of the vertebral joints, protrusion or prolapse of the nucleus pulposus, formation of bone spurs, ligamentous hypertrophy and secondary spinal stenosis, which stimulate or compress the adjacent nerve roots, spinal cord, vertebral artery and cervical sympathetic nerve and other tissues, and cause a variety of symptoms and signs. The clinical symptoms are neck and shoulder pain, dizziness and headache, numbness of the upper limbs, muscle atrophy, spasm of both lower limbs in severe cases, difficulty in walking, even paralysis of the limbs, urinary and fecal disorders, and in severe cases, hemiplegia. This disease is mostly found in middle-aged and elderly people, with a higher incidence in men than in women. With the change of lifestyle, there is a trend of younger patients with cervical spondylosis. 1, cervical degenerative changes With the development of different stages of age, the cervical spine and intervertebral discs can undergo different changes, while the cervical vertebral body undergoes degenerative changes, the intervertebral discs also undergo corresponding changes. 2, trauma factors On the basis of intervertebral disc degeneration, strenuous activities or uncoordinated sports. 3, chronic strain Long-term poor labor posture, the intervertebral disc is subject to pulling, squeezing or twisting from various aspects. 4, cold, humidity Especially on the basis of intervertebral disc degeneration, affected by cold, humidity factors, can cause local muscle tension increases, muscle spasm, increase the pressure on the intervertebral disc, causing damage to the annulus fibrosus. 5, genetic factors Mostly related to congenital development, such as spinal stenosis, can cause cervical spine pathogenesis or higher incidence than other people with normal development.
