[Research progress in treatment of femoral neck fracture in the elderly].

Objective: To introduce the research progress of conservative treatment, internal fixation, hip arthroplasty, and multidisciplinary team (MDT) modes in the treatment of femoral neck fracture in the elderly.

Methods: By consulting domestic and foreign literature in recent years, the characteristics and application of various treatment methods and new treatment modes for femoral neck fracture in the elderly were summarized and analyzed.

Results: The elderly non-displaced femoral neck fracture should be treated surgically, and conservative treatment has a high risk of secondary displacement. The displaced fracture should be operated as soon as possible. There is no difference in long-term functional outcome between hemiarthroplasty and total hip arthroplasty. Hemiarthroplasty has less intraoperative blood loss, shorter operation time, and is suitable for the elderly patients with poor basic condition. Total hip arthroplasty is suitable for the elderly patients with better basic condition and higher demand of life quality. MDT can effectively reduce preoperative waiting time and length of stay, reduce the incidence of medical complications, improve the nutritional status of patients, and reduce the mortality of patients.

Conclusion: Significant results have been achieved in the treatment of femoral neck fractures in the elderly by methods such as internal fixation, hip arthroplasty, and MDT.
