Fractures of the femoral neck occur mostly in middle-aged and elderly people and are associated with a decrease in bone quality due to osteoporosis, the incidence of which is increasing as life expectancy increases. Clinical manifestations: history of fall injury in middle-aged and elderly people, post-injury hip pain, limitation of lower limb movement, inability to stand and walk, external rotation deformity of the affected limb on examination, and shortening of the affected limb on limb measurement. Diagnosis: According to the medical history, to confirm the diagnosis, it is necessary to take frontal and lateral X-rays of the femoral neck to determine the type of fracture Treatment: 1.Non-operative treatment: It is suitable for those who have no obvious displaced fracture, abductor type, embedded type, stable fracture, poor general condition at old age, combined with serious heart, lung, liver and kidney dysfunction, mainly can take lower limb traction, bed rest for 6~8 weeks or wear anti-rotation shoes. 2.Surgical treatment: fracture with displacement or unstable fracture, for elderly patients or fracture does not heal, femoral head necrosis consider surgical treatment. Surgical methods: ① closed reduction internal fixation ② incisional reduction internal fixation ③ artificial joint replacement Pre-operative guidance: traction and braking of the affected limb, strengthening active and passive activities, learning to do isometric contraction of the quadriceps muscle, practicing bed urination and defecation, comprehensive body check before surgery, encouraging coughing and deep breathing, preventing pulmonary infection, urinary tract infection, decubitus ulcers and other complications, good dietary guidance. Postoperative care: 1. Observe the vital signs, keep the drains open, and remove the drains 48-72 hours after surgery. 2. Abduct the affected limb in neutral position and support braking with sandbags on both sides. 3.Guide the patient to turn over from the healthy side to the affected side, and guide the patient to use the puller on the traction frame to lift the hip. 4.Encourage eating high protein and fresh vegetables and fruits and vitamin-rich food. 5.Prevent complications, encourage coughing and coughing up sputum, give turning and patting back, massage the bone ridge to avoid decubitus ulcers and decompensated pneumonia. 6.Functional exercise: functional exercise for closed internal fixation and open internal fixation: no weight-bearing within three months, knee and hip extension exercise. After three months, partial weight-bearing exercise with double crutches. After a year, decide the weight-bearing situation according to the fracture healing situation.
