Vertebral artery type cervical spondylosis is slightly more common than spinal cord type cervical spondylosis, because most of them are caused by vertebral instability and can be easily cured or improved by non-surgical treatment, so fewer people are hospitalized or need surgery. This type mainly causes headache symptoms, so it is also called ascending cervical spondylosis, and it is easily confused with a variety of diseases that cause headaches. It is often difficult to diagnose before vertebral artery imaging examination. Therefore, its diagnosis problem often becomes a controversial issue among relevant departments. Cervical spondylosis includes: cervical type cervical spondylosis, nerve root type cervical spondylosis, spinal cord type cervical spondylosis, vertebral artery type cervical spondylosis, sympathetic nerve type cervical spondylosis, and esophageal compression type cervical spondylosis.
