At what level of disease is surgery necessary? The indicators for surgery are different for different types of cervical spondylosis. Cervical cervical spondylosis is relatively mild and generally does not require surgical treatment. The most common neurogenic cervical spondylosis will first take conservative treatment. If conservative treatment is ineffective for 4~6 weeks, or if the symptoms recur after conservative treatment has an effect, and the number of attacks within a year is too frequent, which seriously affects the quality of life of the patient; even some patients’ nerve roots are so severely stimulated that they appear in forced positions, such as their arms are held up all the time and cannot be put down; there are also patients with muscle weakness or If the patient has symptoms such as muscle weakness or muscle atrophy, surgery is required. In spinal cord cervical spondylosis, surgery is recommended upon diagnosis. If the patient shows signs of spinal cord compression, such as a clumsy fine movement of the hand, a feeling of weakness in the hand, a feeling of stepping on cotton, or a feeling of banding on the body, these are absolute indications for surgery. Sympathetic cervical spondylosis can also be treated by surgery if it is recurrent and the diagnosis is clear. The sooner surgery is done, the better? If the patient meets the criteria for surgery, the sooner the better. The longer the nerve is compressed, the more severely the function is impaired, and the slower the patient will recover after surgery. If the surgery is done as soon as possible, the nerve function will be restored faster, but of course the doctor will make the right surgery plan according to the patient’s actual condition. What is the effect of surgery? The effect of surgery is determined by the severity and type of cervical spondylosis and the duration of the disease. For example, in the case of neurogenic cervical spondylosis, the relief of symptoms after surgery is usually very obvious; however, in the case of spinal cord cervical spondylosis, if the spinal cord has been compressed for a longer period of time, the symptoms will not be completely relieved in the early postoperative period, and the patient will have residual symptoms and need a period of time to recover slowly.
