Elderly patients with conservative treatment of femoral neck fracture in the bone unhealing rate, avascular necrosis rate and bed incidence of complications are very high, often need surgical treatment, Currently Artificial arthroplasty better able to load the early running, and significantly improved the quality of life. Orthopedist has been universally acknowledged, which was also hemiarthroplasty for and hip arthroplasty mainly, But these indications of operation and the pros and cons of surviving in numerous disputes, By comparing our double-action Hemiarthroplasty with total hip arthroplasty for femoral neck fracture in the elderly average operative time, The average blood transfusion, the average length of stay, average hospital charges, early complications, Harris score, Oxford hip score standards evaluation discussion bipola Femeral Head placement with total hip arthroplasty in the treatment of femoral neck fracture in the elderly: the advantages and disadvantages.

老年患者股骨颈骨折保守治疗的骨不愈合率、股骨头缺血坏死率及卧床并发症发生率很高，常需要行手术治疗，目前应用人工关节置换疗效较好，能早期负重行走，生活质量明显提高，已得到骨科医师的普遍认同，其中又以人工股骨头置换术和人工髋关节置换术为主，但这些术式的适应证及利弊尚存在诸多争议，我们通过比较双动人工股骨头置换与全髋关节置换治疗老年人股骨颈骨折的平均手术时间、平均输血量、平均住院时间、平均住院费用、早期并发症、Harris评分、牛津髋关节评分标准评价来探讨双动人工股骨头置换与全髋关节置换在老年人股骨颈骨折治疗中的优势与劣势。

As examples of applying our method, the quantum vacuum effect induced by two moving boundaries is studied in the case where the two mirrors oscillate resonantly.
