Femoral neck fractures occur mostly in the elderly, with a higher incidence in women than in men. Older adults have varying degrees of osteoporosis, and women in particular are more prone to fractures due to the early onset of osteoporosis for physiological reasons (menopause). For elderly people with femoral neck fracture, artificial hip arthroplasty is a successful operation that can immediately relieve and eliminate joint pain, increase limb mobility and improve the quality of life of patients. I. Pre-surgery preparation: The surgeon will conduct a thorough examination of the patient before surgery, including: physical examination, laboratory tests, dental examination, urinary tract examination, etc. These necessary examinations will be helpful in assessing the patient’s physical condition and formulating a surgical plan to reduce the chance of infection after surgery. The operation takes about 1 to 1.5 hours. The surgeon removes the femoral head and the diseased bone and cartilage, installs an artificial prosthesis and restores the function of the hip joint. Post-operative rehabilitation 1. Functional exercise 1) Hip extension: A. Tighten the gluteal muscles and do a slight hip lift, hold for five minutes. B. Straighten the knee and extend the lower limb with the joint backward. 2) Hip flexion: A, lying down, agitate the heel toward the hip, pay attention to hip flexion no greater than 90 degrees. B, standing, pay attention to hip flexion no greater than 90 degrees. 3) knee extension: lift one leg about 15 cm, hold for 5 seconds, then change one leg and repeat 10 times. 4) Hip abduction: A, lying in bed, keep the toes up, straighten the lower limb and spread the lower limb outward. B, standing with the lower limb straight, spread the lower limb outward, hold for 5 seconds, repeat 10 times. 2, the correct posture of getting out of bed 1) move the affected limb closer to the edge of the bed 2) lower the lower leg slowly 3) try not to put weight on the affected side 4) hand on the healthy side to hold the walker, hand on the affected side to hold the edge of the bed, stand slowly. 3. Correct posture of using crutches 1) Stand with the left crutch first 2) Step on the right foot 3) Step on the right crutch 4) Step on the left foot IV. Prevention of complications 1. The fundamental measure. 3. Prevention of pulmonary infection: Ask the patient to sit up and encourage coughing to prevent pneumonic pneumonia. V. Postoperative follow-up One month, three months, six months, twelve months after surgery, and then once a year afterwards, patients should come to the hospital for routine follow-up examination and X-ray. The purpose of the follow-up visit is to guide the patient for further rehabilitation training in order to achieve the best results of the operation.
