I. Purpose of surgery: The main purpose of surgical treatment is to relieve the severe compression on the spinal cord or blood vessels caused by disc herniation, bone flab formation or ligament calcification, and to rebuild the stability of the cervical spine. Once diagnosed, spinal cord cervical spondylosis should be actively operated on if non-surgical treatment is ineffective and the condition is worsening; if the symptoms of neurogenic cervical spondylosis are heavy and affect the patient’s life and work, or if muscle movement disorders occur; if conservative treatment is ineffective or the effect is not consolidated and other types of cervical spondylosis are recurrent, surgery should be considered.
