1, the first and second postoperative days to start active breathing exercises to prevent complications of the cardiopulmonary system, such as deep inhalation breathing and blowing up balloons, etc.; 2, 3 to 5 days postoperative lower limb muscle exercise (1) Quadriceps training: the patient’s quadriceps muscle thigh tightening, the lower limb was in a neutral position, the knee downward pressure, the knee to keep the knee joint straight for 5 seconds, and then relax for 5 seconds; (2) biceps femoris training: the patient’s lower limb was in a neutral position, the heel of the foot down, the knee to maintain Straight position, hold for 5 seconds, relax for 5 seconds; (3) gastrocnemius muscle training: first let the patient put the ankle force plantarflexion (limb toes straight forward, heel pull back), then ankle dorsiflexion position (toes pull back, push the heel forward), pay attention to keep the knee straight; (4) gluteus maximus muscle training: tighten the buttocks 5 seconds, relax for 5 seconds; (5) postoperative day 3 can be carried out on the lower extremities of the straight-legged elevation. 3, 1 week postoperative turn over exercises, prone position of the lumbar back muscle exercises (1) double elbow support or both hands holding the hanging rings above the bed to raise the upper body, while the hips lifted away from the bed, hold for 10-15 seconds, repeat 5-10 times, according to the patient’s physical ability to exercise 2-3 groups per day; (2) “three-point style”: the patient bends the knee to put the feet flat on the The patient bends the knees and puts the feet flat on the bed, bends the elbows, and then takes the feet and the head as the pivot point to do the hip movement, i.e., the hip lifting movement. (3) “Flying Swallow”: the patient is lying in prone position, both upper limbs are placed on both sides of the torso, the head, both lower limbs and both lower limbs leave the bed at the same time, supported by the abdominal muscles. The amount of exercise is gradually increased from a small amount, each action in place should be maintained for more than 5 seconds before relaxing the muscles, each action should be more than 10 times, and then gradually increase the amount, until recovery. 4, four weeks after surgery, you can instruct the patient to get out of bed in the prone position, the formula is: bring a waist cuff, preferably a lumbar back support. After turning prone, one leg down to the ground, and then use both hands to support the upper body, when the torso is close to upright, and then move the other leg down to the ground, in order to avoid spinal flexion. During this period, the patient can perform spinal backward extension, lateral bending and moderate rotation exercises in the upright position, but avoid forward flexion of the spine and posture. 5, 3~4 weeks after the operation can be protected by waist circumference down to the ground indoor activities, 6~8 weeks outdoor activities, 3 months should not bend over, six months should not bend over and weight bearing.
