Neck of femur fracture is a relatively common fracture in clinical practice. Patients with femoral neck fracture need to stay in bed for a long period of time. In the early stage of fracture, the patient’s diet needs to eat light food, such as green vegetables. Because in the early stage of fracture, the patient’s gastrointestinal peristalsis slows down, which can easily lead to constipation. In the middle stage of fracture, patients are encouraged to eat more high protein foods, such as soybean stewed pig’s feet and other foods, in order to promote bone healing. In the late stage of fracture, food that replenishes kidney and calcium should be eaten, because kidney and calcium replenishment will accelerate fracture healing even more. All in all, the principle of diet for patients with femoral neck fracture is comprehensive, balanced and moderate, which is the simplest and smartest dietary principle, and it is best to make dietary adjustments under the guidance of doctors to better promote fracture healing.
