The basic care of patients should be strengthened to prevent postoperative complications: (1) prevention of pressure sores: turn over on time, massage the pressurized areas and protruding parts of the bone ridge, and the bed unit should be kept clean and dry; (2) prevention of pulmonary infections: strengthen turning, tap on the back, and do deep breathing and coughing activities; (3) prevention of urinary tract infections: keep the urinary catheter draining smoothly and do not twist or be pressurized. Patients can be given liquid diet such as milk, vegetable soup, chicken soup, etc. 6h after waking up from general anesthesia, and semi-liquid food such as noodles 1d~2d after surgery. Patients without underlying diseases can be given ordinary diet such as rice and steamed bread 1 week after surgery, and the diet should be light, easy to digest and rich in nutrition, so as to assist in improving the body’s resistance. Rehabilitation training can effectively prevent muscle atrophy and joint stiffness, and muscle massage and auxiliary joint active and passive activities can be given to the upper and lower extremities in the early postoperative period after the vital signs are stabilized, with muscle massage five or six times a day for 20 min to 30 min each time. The upper limbs mainly exercise the grip and pinch function of the hands, and assist in restoring muscle strength. The lower limbs mainly strengthen the exercise of hip flexion, knee flexion and ankle joint. Exercise is mainly active activities, supplemented by passive activities, and the limbs are placed in functional position. Patients should wear a neck brace to protect the neck and avoid neck flexion, extension and rotation activities for 3 months after discharge. If there is severe pain in the neck or difficulty in swallowing, there is a feeling of obstruction which may be due to the displacement or dislodgement of the bone graft, and the patient should return to the hospital for review immediately. If it is indicated that the intervertebral space in the operated area has been completely fused, functional exercise of the neck can be carried out, starting with neck flexion and extension, left and right rotation activities, and then neck rotation activities, paying attention to the neck not to do strenuous activities to prevent injury. Functional exercise should be performed gradually, and if neck discomfort occurs, the activity should be stopped immediately.
