1.Overview Elderly patients are a high-risk group for fractures because many are accompanied by different degrees of osteoporosis. According to statistics, hip fractures account for 23.79% of total body fractures in people over 65 years old, of which femoral neck fractures account for 53%. Femoral neck fracture is one of the most serious complications of osteoporosis in the elderly, often occurring on the basis of minor trauma such as falls. Once a fracture occurs, 1/3 of patients die within 1 year of the fracture, and 1/3 of patients are able to return to pre-injury living conditions. However, most patients have a reduced quality of life and are often accompanied by more medical complications and have a poor prognosis. 2, senior people need to prevent femoral neck fracture Because most of the senior people are accompanied by osteoporosis and reduced bone strength, minor trauma such as falls can lead to hip, wrist or spine fractures; at the same time, senior people have reduced mobility and slow response to external emergencies, so prevention of daily falls is of great significance to reduce the occurrence of fractures. 3. Treatment of senior femoral neck fracture For patients who are not contraindicated to surgery, early surgical treatment can largely prevent bedridden complications and allow patients to resume activities on the ground as soon as possible. Conservative treatment is the treatment modality for patients who cannot undergo surgery, but its high incidence of bedridden-related complications, such as pneumonia, lower extremity venous thrombosis, and pressure sores, greatly reduces patients’ quality of life and increases their recent mortality.
