There are six types of cervical spondylosis. Cervical type, nerve root type, vertebral artery type, sympathetic type, spinal cord type, and mixed type. 1.Cervical type cervical spondylosis Neck pain is predominant and activity is limited, usually appearing in the morning after waking up. It is often caused by cold or forced body position. 2.Neurogenic cervical spondylosis The cervical intervertebral disc itself is degenerated and secondary pathological changes stimulate or compress the cervical nerve roots, resulting in corresponding neurological symptoms and signs in the human body, which is called neurogenic cervical spondylosis. 3.Vertebral artery type cervical spondylosis The degeneration of the cervical disc itself and secondary pathological changes stimulate or compress the vertebral artery, resulting in dizziness, neck pain, headache and other signs and symptoms. 4.Sympathetic cervical spondylosis The degeneration of the cervical intervertebral disc itself and secondary pathological changes stimulate or compress the sympathetic ganglion of the neck, resulting in symptoms and signs such as headache and neck pain in human body is called sympathetic cervical spondylosis. 5.Spinal cord type cervical spondylosis Spinal cord type cervical spondylosis is caused by degeneration of the cervical disc itself and secondary pathological changes that stimulate or compress the spinal cord, resulting in neck pain, weakness and numbness of the limbs, reduced fine motor function of the hands, such as difficulty in writing and tying buttons, difficulty in rapid gait and unstable gait of the lower limbs, and a sense of stepping on cotton. Pain is a more common symptom, characterized by aggravation during sleep and relief during the day. The motor disorder after spinal cord compression is lower extremity first and then upper extremity, manifested as weakness of lower extremity, clumsy gait and trembling, etc. It gradually develops into increased muscle tone, easy to fall, and spastic paralysis in late stage. 6.Mixed cervical spondylosis The cervical spondylosis in which two or more types coexist is called mixed cervical spondylosis.
