Cervical spondylosis is a degenerative change of the cervical disc and its secondary pathological changes involving the surrounding tissue structures (nerve roots, spinal cord, vertebral artery, sympathetic nerves, etc.), with corresponding clinical manifestations. Degenerative changes of the cervical spine without clinical manifestations are called cervical degenerative changes. With the increase in the number of people engaged in the modern way of working with their heads down, such as the widespread use of computers and air conditioners, the chances of people flexing their necks and suffering from wind, cold and dampness are increasing, resulting in the increasing prevalence of cervical spondylosis, and the trend of younger age of onset. Clinical diagnostic criteria 1, cervical type: with a typical history of falling pillow and the above-mentioned cervical symptoms and signs; imaging examination can be normal or only have physiological curvature changes or mild spinal space narrowing, with little bone superfluous formation. 2, nerve root type: symptoms (numbness, pain) and signs of radicular distribution; positive intervertebral foramen squeeze test or/and brachial plexus pull test; imaging findings are basically consistent with clinical manifestations; pain due to extra-cervical pathology (thoracic outlet syndrome, tennis elbow, carpal tunnel syndrome, elbow tunnel syndrome, frozen shoulder, biceps longus tendinitis, etc.) is excluded. 3, spinal cord type: clinical manifestations of cervical spinal cord damage; imaging shows cervical degenerative changes, cervical spinal stenosis, and confirms the presence of cervical spinal cord compression consistent with clinical manifestations; except for progressive amyotrophic lateral sclerosis, spinal cord tumor, spinal cord injury, secondary adhesive arachnoiditis, multiple peripheral neuritis, etc. 4, sympathetic type: diagnosis is more difficult, and there is a lack of objective diagnostic indicators. Clinical manifestations of sympathetic nerve dysfunction and imaging show segmental instability of the cervical spine are present. In some patients with atypical symptoms, if the symptoms are reduced after planetary ganglion closure or high cervical epidural closure, it will help the diagnosis. Vertigo due to other causes: (1) Otogenic vertigo: vertigo due to vestibular dysfunction in the inner ear. For example, Meniere’s syndrome and embolism of the auditory artery in the ear. (2) Ophthalmogenic vertigo: refractive error, glaucoma and other ophthalmic disorders. (3) Vertigo of cerebral origin: insufficiency of blood supply in vertebrobasilar artery due to atherosclerosis, lacunar cerebral infarction; brain tumor; sequelae of traumatic brain injury, etc. (4) Vascular vertigo: Vertebrobasilar artery insufficiency due to stenosis of V1 and V3 segments of vertebral artery; hypertension, coronary heart disease, pheochromocytoma, etc. (5) Other causes: diabetes mellitus, neurosis, overexertion, long-term sleep deprivation, etc. (5) Vertebral artery type: previous episodes of sudden collapse with cervical vertigo; positive rotational neck test; imaging shows segmental instability or hook vertebral joint hyperplasia; except for other causes of vertigo; positive neck motion test. (6) Other types such as esophageal cervical spondylosis, cervical vertebrae with anterior osteoarthritic hyperplasia compressing the esophagus causing swallowing difficulties. This can be confirmed by barium esophagogram.
