There are many patients with cervical spondylosis who are afraid of surgery due to their lack of understanding of surgery, and delay and delay until after their symptoms are very serious, missing the best time for surgery and resulting in unsatisfactory post-operative recovery. Under what circumstances should surgery be performed as early as possible? In neurogenic cervical spondylosis, if there is no relief after more than one week of conservative treatment such as dehydration, swelling reduction and braking, surgery should be considered as early as possible due to severe radiated pain in the upper extremity caused by a herniated cervical disc compressing the nerve root. In spinal cord cervical spondylosis, if the spinal cord is compressed by a herniated cervical disc or ossification of the posterior longitudinal ligament, once there is instability in holding objects, inflexibility in fastening, weakness of limbs and unstable walking, surgery should also be performed as early as possible. The main purpose of cervical spine surgery is to save the function of the spinal cord, not just to improve the quality of life. After the degeneration of spinal cord neuronal cells, the possibility of recovering them again is almost zero. For patients with more severe spinal cord compression, a minor head and neck trauma in daily life may cause limb paralysis, and the results of further emergency surgery are not too satisfactory, and the degree of postoperative recovery is beyond human control.
