Rehabilitation time after internal fixation of femoral neck fracture is approximately 3 to 6 months. There are individual differences in rehabilitation time depending on the patient’s specific condition. Most femoral neck fractures are caused by trauma. After femoral neck fracture, the blood vessels around the femoral neck are damaged, there is little collateral circulation in this area, the local blood circulation is poor, and the recovery is relatively slow. On the other hand, femoral neck fracture leads to increased intramedullary pressure, resulting in tissue swelling and hypoxia, which also affects the healing speed. Therefore, the recovery time after internal fixation of femoral neck fracture is generally longer, about 3~6 months, and some patients may need longer time. After femoral neck fracture, according to the early rehabilitation content, do isometric muscle contraction training, ankle pump training, etc., to create conditions for fracture healing, and gradually start to increase the amount of training, increase weight-bearing training, down to the ground activities need crutches, in order to reduce the pressure of the fracture broken end. It is recommended that patients under the guidance of a professional doctor for treatment to avoid adverse consequences.
