Femoral neck fractures often occur in the elderly, and their incidence is increasing as people live longer, especially with the aging population, which has become a serious social problem. Femoral neck fractures with less severe displacement or patients who are relatively young are mostly treated with closed reduction internal fixation. The main training contents during the bedside period include: (1) isometric contraction of the muscles of the affected lower limb; (2) active and passive movement of the affected lower limb, i.e., the joint; (3) functional activities of the normal limb; (2) complete weight-bearing is not recommended within 3 months after surgery: decide whether to put on weight and the degree of weight-bearing according to the repositioning and fixation to avoid the failure of internal fixation. Fracture site: the closer the femoral neck fracture is to the femoral head, the higher the chance of non-union and femoral head necrosis; 4. Age: femoral neck fractures in middle-aged and elderly patients are prone to non-union, while femoral neck fractures in young adults are prone to femoral head necrosis; 5. Weight-bearing for 3 months after surgery: because femoral neck fractures are prone to femoral head necrosis, the start time and intensity of weight-bearing training should be decided by the doctor in charge according to the bone scab Femoral neck fracture can be weight bearing after 12 weeks simply from the perspective of fracture healing, but because of the late onset of femoral head necrosis, reducing weight bearing should be adhered to until 1~1.5 years, premature abandonment of abduction activities is a common cause of femoral head necrosis; 6, diligent review of X-rays: even if the fracture heals, it should be tracked for 3~5 years. Studies have shown that about 85% of femoral head necrosis occurs within 3 years after the fracture, and 98% occurs within 5 years. For the evaluation of the treatment and efficacy of femoral neck fractures, the fracture healing should not be observed only, but should be followed up to 5 years after the injury. If there is a decrease in height of the femoral head and sclerosis of the hyaline zone, it indicates that the femoral head has already been precipitated by necrosis, and active measures should be taken to prevent its further development.
