After femoral neck fracture surgery, you need to keep the wound clean, avoid infection, pay attention to prevent dislocation, moderate functional exercise and other problems. Femoral neck fracture is usually treated by closed reduction screw internal fixation (head preserving treatment) or artificial hip replacement, and it is necessary to pay attention to keep the wound clean after the operation. 1. In case of closed reduction screw internal fixation, bed rest is needed for 2~3 months after the operation, and avoid weight bearing on the ground. Functional exercises can be carried out during bed rest, such as functional exercises of knee joint and ankle joint, isometric contraction exercises of lower limb muscles, and so on. This can effectively prevent joint stiffness and lower extremity venous thrombosis. 2. In case of artificial hip replacement, you can go down to the ground within 3 days after the operation, and you need to pay attention to avoid excessive internal rotation of the affected limb and deep squatting (to prevent dislocation of the femoral head). Femoral neck fracture after surgery should be regular follow-up, once there is a change in the condition of the patient to consult a doctor in a timely manner, the diet to eat more high-quality protein rich in vitamins and fruits, which will help the recovery of the fracture.
