Cervical spondylosis is one of the most common disorders in pain medicine. The cervical spine is located between the head, chest and upper extremities and consists of seven cervical vertebrae arranged in a stacked tile pattern from top to bottom. The cervical spine is the smallest, but most mobile, most frequently active, and heavily weight-bearing segment of the spine. Cervical spondylosis can be caused by abnormal stimulation of the muscles, tendons, ligaments, nerves, blood vessels and other tissues around each cervical vertebra. Due to the change of modern life and work style, the incidence of cervical spondylosis is significantly higher than before, and there is a trend of low age, complicated symptoms and easy recurrence. Cervical spondylosis can be clinically classified into the following types according to clinical manifestations: 1. Cervical type, which is the mildest type of cervical spondylosis, mainly manifests as follows: (1) abnormal sensations such as head, neck and shoulder pain, accompanied by corresponding pressure points; (2) X-ray cervical spine showing curvature changes or intervertebral joint instability and other manifestations. This type is the initial manifestation of cervical spondylosis, reminding patients that they should pay attention to neck health care, and if they still do not pay attention to it, the condition may be aggravated. This type can improve the symptoms through neck health care exercises and a variety of physical therapy. 2.Neurogenic type, which is the most common type of cervical spondylosis, is mainly manifested as follows: (1) with typical radicular symptoms, unilateral (bilateral) hand and upper limb numbness and pain; (2) positive head press test or arm length pull test; (3) narrowing of the intervertebral foramen and other manifestations can be seen in the oblique X-ray film. The symptoms of this type can be severe or mild, most patients can tolerate the pain and numbness, a few patients show persistent pain and numbness, serious cases can not sleep. The effect of oral non-steroidal painkillers is not obvious. This type must go to a regular hospital for scientific diagnosis and treatment. Do not blindly traction, massage and manipulation reset treatment, unreasonable treatment can aggravate the condition to cause maximum damage. 3, sympathetic nerve type, only this type is rare, the main manifestations are: (1) dizziness, blurred vision, tinnitus, hand numbness, tachycardia, precordial pain and other symptoms; (2) X-ray film suggests that the cervical spine instability or degeneration. This type has obvious efficacy with regular treatment. 4, vertebral artery type, this type is more common, the main manifestations are: (1) dizziness, in severe cases, sudden collapse with cervical dizziness; (2) positive rotation test; (3) X-ray film can be seen in the cervical vertebrae segmental instability or vertebral body multiple osteophytes; (4) vertebral arteriography test can be seen in the narrowing of the vertebral artery; (5) some patients are accompanied by sympathetic nerve symptoms. This type is more difficult to treat and must be treated formally. 5, spinal cord type, this type is the most serious type of cervical spondylosis, depending on the performance of the spinal cord compression site, there is a possibility of paraplegia in serious cases. This type is more insidious and can only be diagnosed by MRI examination of the cervical spine. The main treatment for this type requires surgery to relieve the spinal cord compression. 6.Mixed type, where the above two or more types exist at the same time, is more difficult to treat. Therefore, the prevention of cervical spondylosis is especially important in modern working life: (1) prevent traumatic injury; (2) correct poor posture in life, avoid prolonged continuous ambulation or low head work; (3) perform appropriate functional exercises for the neck, such as neck health exercises, etc.
