Cervical spondylosis is a common and frequent disease in orthopedic surgery. In recent years, with the accelerated pace of life and changes in work style, the incidence of this disease has been increasing year by year and is trending toward a lower age. As a modern and occupational disease accompanying with social civilization, it is of positive significance today to let patients understand and prevent this disease. I. What is cervical spondylosis? Cervical spondylosis is a syndrome of a series of clinical symptoms caused by degenerative degeneration of the cervical disc and osteophytes of the cervical spine. It can be divided into cervical type, nerve root type, spinal cord type, vertebral artery type, sympathetic nerve type and other types. Cervical spondylosis often manifests clinically as pain in the neck, shoulder and arm, upper back of the scapula and thoracic region, arm and hand numbness, muscle atrophy and even tetraplegia. It can occur at any age, with middle-aged and elderly people above 40 years old being the most common. Cervical spondylosis is characterized by high incidence, long treatment time and easy recurrence after treatment. Second, the physiological structure of the cervical spine The cervical spine bones are small, and the top is burdened with a larger volume and weight of the head, while the cervical vertebrae have a larger range of motion such as extension and flexion, rotation and lateral flexion, thus forming an unstable skeletal structure mechanically, and in the physiological state, they are kept in balance with the help of the strong bones and soft tissues of the cervical spine. The common factors that cause cervical discomfort are bad posture, head and neck trauma, excessive movement of the head and neck, infection of the throat, physical labor, and the mechanism that causes cervical discomfort. Soft tissue injury. As we age, degenerative pathological changes occur in the intervertebral discs, joint capsule and ligaments of the cervical spine one after another. The main symptoms of cervical spondylosis are pain in the head, neck, arm, hand and forehead, and progressive sensory and motor disorders of the limbs, and in severe cases, weakness of the limbs, even incontinence and paralysis, and the corresponding clinical manifestations such as dizziness, panic and heartbeat when the vertebral artery and sympathetic nerve are involved. Prevention and treatment of cervical spondylosis 1, correct poor posture, reduce strain, every 1-2 hours of head down or head up, need to do neck activities to reduce muscle tension. 2.Avoid and reduce acute injuries, such as avoiding lifting heavy objects and not tightening the emergency brake. 3.Prevent wind and cold, wind and cold make local blood vessels contract and blood flow decrease, which hinders the metabolism of tissues and waste removal, causing local muscle tension. 4, actively treat local infections and other diseases. 5, the pillow can not be too high, too hard or too flat.
