“…Material properties. The material parameters of the 3D model were determined according to the relevant literatures 15,16 . The elastic modulus of the uterus is 2.0 MPa, and its Poisson's ratio is 0.45 with the density being of 1120 kg/m 3 .…”

“…Ma et al 15 established a finite element model of USL and CL, through which they analyzed the stress distribution and deformation with USL and CL under different values of IAP. Chen 16 established a relatively complete normal female pelvic three-dimensional finite element model, and she found that BL and USL play a main role in maintaining normal position of the uterus. Rubod 4 performed a simulation of pelvic mobility with a validated numerical model in a normal situation (standing up to lying down) or induced pathological ones, and they found that uterine ligaments play an important role in pelvic statics.…”

Uterine prolapse is a common gynecological disease, which seriously affects the quality of life and physical and mental health of elderly women. The aim of this study was to analyze the influence of different conditions (intra-abdominal pressure (IAP) and posture) on stress and displacement of uterine ligaments using the finite element method, and evaluate the contribution of uterine ligaments on uterus. The three-dimensional (3D) models of retroverted uterus and its accessory ligaments were established, loads and constraints were set in ABAQUS software, and the stress and displacement of uterine ligaments were calculated. The uterine displacement increased with the increase of IAP, and then the stress and displacement of each uterine ligament also increased. The uterine displacement was in the order of forward < upright < backward with different postures, and USL, CL and RL got larger values when the body was backward, while BL got a larger value when the body was forward. With the same condition, the stress of the uterine ligaments was in the order of USL > BL > CL > RL, and the displacement of the ligaments was in the order of BL > RL > USL > CL. The contribution of each uterine ligament changing with different IAP and postures was studied through finite element analysis, and the research results were consistent with the clinical data, which can provide a basis for exploring the mechanism of uterine prolapse.

“…With the progressive advancement of biomechanics research in the female pelvic floor, the application of finite element (FE) analysis has introduced novel perspectives to biomechanical research of POP. Currently, the majority of research in this field is dedicated to finite element models, which are based on the MRI of pelvic floor individual tissues and organs, as well as the measurement of related parameters ( 13 – 15 ). The research on the overall mechanical balance principle, stress-induced injury mechanism, and organ interactions in the pelvic support system is still in its preliminary exploration stage ( 16 ).…”

The prevalence of pelvic organ prolapse (POP) has been steadily increasing over the years, rendering it a pressing global health concern that significantly impacts women’s physical and mental wellbeing as well as their overall quality of life. With the advancement of three-dimensional reconstruction and computer simulation techniques for pelvic floor structures, research on POP has progressively shifted toward a biomechanical focus. Finite element (FE) analysis is an established tool to analyze the biomechanics of complex systems. With the advancement of computer technology, an increasing number of researchers are now employing FE analysis to investigate the pathogenesis of POP in women. There is a considerable number of research on the female pelvic FE analysis and to date there has been less review of this technique. In this review article, we summarized the current research status of FE analysis in various types of POP diseases and provided a detailed explanation of the issues and future development in pelvic floor disorders. Currently, the application of FE analysis in POP is still in its exploratory stage and has inherent limitations. Through continuous development and optimization of various technologies, this technique can be employed with greater accuracy to depict the true functional state of the pelvic floor, thereby enhancing the supplementation of the POP mechanism from the perspective of computer biomechanics.
