Femoral intertrochanteric fracture is a fracture that often occurs in falls in the elderly, and conservative treatment is prone to complications such as crushing pneumonia, lower limb venous thrombosis, pressure sores, urinary tract infection, constipation, and even life-threatening due to decreased physiological compliance in bed-ridden people for long periods of time; therefore, there is an increasing tendency for aggressive surgical treatment in modern times. With the widespread use of surgery and the improvement of surgical skills, postoperative rehabilitation becomes very important. Good and timely rehabilitation not only promotes the recovery of motor function of the affected limb, but also has positive significance in preventing complications and concomitant diseases, and is even more important in improving the quality of patient’s survival. Pre-operative rehabilitation guidance Do pre-operative health assessment, cooperate with the hospital to carry out all systems of examination, timely detection and treatment of complications, and give a high-calorie, high-protein, high-vitamin, crude fiber-rich diet to enhance the body’s resistance and tolerance and prevent the occurrence of complications. Preoperatively, the patient was instructed to urinate and defecate in bed and to use the stool correctly so as to adapt as soon as possible after surgery. Preoperatively, the patient should be instructed to train deep breathing, coughing and coughing to prevent postoperative pneumonia caused by long-term bed rest. For deep breathing training, practice blowing up balloons. For limb training, you can finger-push the patella, while performing double upper limb muscle strength training and chest expansion exercise to prevent cardiopulmonary system diseases, and do circular or squeezing massage from the ankle to the center of the hip, which can significantly reduce the incidence of deep vein thrombosis. Postoperative rehabilitation care Closely observe the vital signs, perform cardiac monitoring, and observe the changes of patient’s consciousness, pulse, blood pressure and respiration. For those who are not awake from anesthesia, they should lie down with their heads tilted to the side, and report any abnormalities to the doctor in time. Keep the incisional drainage tube unobstructed, observe the color, nature and amount of drainage fluid and record it. The drainage bag should be lower than the wound position to prevent retrograde infection. Squeeze the drainage tube frequently, pay attention to protect the drainage tube when moving the patient or turning the patient, prevent distortion and pressure, keep the incision dressing clean and dry, and ask the doctor to change it in time when there is blood and fluid oozing. The patient should be in the supine position, keep the affected limb in the abducted neutral position, and wear a soft pillow between the legs to prevent the affected limb from external rotation and inversion, and a soft pillow under the knee to encourage the patient to do flexion and extension of toe and ankle exercises to increase the muscle strength and blood circulation of the lower limb to facilitate swelling reduction and accelerate blood circulation. Closely observe the blood circulation and sensation of the affected limbs, massage the muscles frequently, and also use anti-thrombotic drugs. Appropriately apply patient sedative and analgesic drugs to ensure patient rest. Assist the patient to do chest expansion exercise and turn over, tap the back, encourage the patient to cough and cough up sputum effectively, and give nebulized inhalation if necessary. Ask the patient to drink more water to dilute sputum and increase urine output. Keep the perineum clean to prevent urinary tract infection. Eat more food rich in coarse fiber, do abdominal circular massage frequently, from right to left, week by week, to increase intestinal peristalsis, encourage patients to exercise in bed as early as possible and get down to the floor as early as possible to prevent the occurrence of constipation. After the operation, the patient’s family members can be instructed to reach the lower part of the patient’s waist and buttocks with both hands crossed together to elevate the buttocks every 2 hours; on the second day, the patient can be instructed to stir the bed with the healthy foot to keep the body off the bed to prevent the occurrence of pressure sores. The patient’s position should be changed once every 2 hours, and the pressure area should be massaged frequently. Postoperative rehabilitation training After the anesthesia disappears on the postoperative day, the patient should be encouraged to perform quadriceps contraction, ankle dorsiflexion or flexion, and toe joint exercise, and due to the stimulation and physical exertion of the surgery on the postoperative day, the patient should exercise once or twice, for 5 minutes each time, from passive exercise to active exercise. On the 1st postoperative day, instruct the patient to perform resting contraction of quadriceps, straighten the knee joint, make the lower limb muscles exert, and then relax, which can promote blood circulation and prevent muscle atrophy, avoid excessive activities, and achieve gradual progress. On the second day after surgery, continue to exercise the leg muscles and joint activities, flexion and extension of the ankle joint on the affected side or resistance activities, or use the Continuous Passive Motion Machine (CPM) to perform passive exercises of hip, knee and ankle flexion and extension with an amplitude of 30° to 40° for 30 minutes each time, twice a day, to the extent that no pain or slight pain is felt. From day 3 to day 7 postoperatively, the exercise of leg muscle and joint movement was continued. At 1 week after surgery, the knee joint can be fully flexed, and the patient can sit on the bedside with the affected knee swinging down to increase the range of motion and muscle strength of the knee joint and prevent muscle adhesions. At 2 weeks after surgery, the patient was assisted to leave the bed for functional exercise, holding the crutches at the bedside and walking slowly in the ward, without weight on the affected limb, with the healthy side following, gradually increasing the walking distance and time, so that the patient did not feel fatigue. Four weeks after surgery, X-ray examination was done to understand the growth of bone scabs and to decide the time to put weight on the ground. The patient should start to do heel lifting exercises and half squatting exercises to increase the muscle strength for weight bearing, and full weight bearing should be allowed only after there is a large amount of bone scab growth and fracture line is blurred on X-ray. Discharged patients are reviewed regularly on an outpatient basis for 3, 6, and 12 months, respectively. After discharge, it is important to maintain the correct position of the hip and gradually increase mobility, limb strength and the ability to walk with weight on the lower extremities. It is required that both knees should not cross, sit in a low chair or sit with knees bent in bed for 3 months.
