Abstract: Pelvic floor dysfunction is a common disease in elder women. The incidence increases year by year，it has a serious impact on the health and quality of life in elder women. With the development of medical imaging technology and computer technology，the finite element analysis of pelvic biomechanics becomes the hot spot in the study of pelvic floor dysfunction. At present，the finite element analysis has already been widely used in orthopedics，however，because of the complex anatomy of pelvic floor，and the difficulty of building a model accurately，the domestic research on the finite element of pelvic floor is still in its infancy. The establishment of the finite element model of pelvic floor and the mechanical analysis，not only can help the gynecologist to understand the mechanism of pelvic floor dysfunction，but also can help them to make the optimal surgical plan and to predict the efficacy of the treatment. With the continuous improvement of medical imaging technology and computer hardware，we believe that the application of finite element analysis method will play an important role in the gynecology.
