Straightening of the physiological curvature of the cervical vertebrae is mostly caused by poor posture, chronic strain injury, degenerative diseases and other factors, and can be handled through general treatment, physical therapy and surgery. 1. General treatment: maintain good sitting and standing postures, avoid prolonged bowing of the head, work and other postures, and choose the right height and softness of the pillow when sleeping, not too high and too hard. 2. Physical therapy: you can relieve muscle spasm through hot compresses, massage and other physical therapy, relax the neck muscles, take the initiative to carry out neck exercises to enhance the strength of the neck muscles. 3. Surgical treatment: If there is cervical degenerative disease, damage to the spinal cord and nerve roots, and the effect of conservative treatment is unsatisfactory, surgical treatment can be considered, such as anterior discectomy, intervertebral bone grafting and other surgical methods for treatment. The arc of the human cervical vertebrae protruding forward is called the physiological curvature of the cervical vertebrae, which has a certain role in increasing the elasticity of the cervical vertebrae, cushioning the shock as well as protecting the spinal cord and the brain. If there is a straightening of the cervical vertebral curvature, the patient should be examined by the hospital in time to clarify the cause of the disease and then carry out the targeted treatment.
