“…Finite element modelling of pelvic mobility has been investigated by several authors . To build a consistent FE model, three fundamental elements have to be known: the mechanical properties, the geometry and the boundary conditions.…”

“…In a more mechanical context, finite element (FE) modelling has been proposed to better understand the role of suspension structures such as ligaments on pelvic mobility and the physiopathology of prolapses, and to predict the motion of an organ. In this context, the use of a FE modelling strategy would help define the relative importance of each suspension structure more accurately and better understand the influence of the pathology on mobility, but this requires experimental data for validation of the model.…”

International audiencePelvic mobility is essential for good pelvic organ function. Any modification may be a sign of pathology. The objective of this study was to define a methodology to quantify pelvic mobility. An analysis protocol based on an image registration technique performed on dynamic magnetic resonance imaging sequences is presented. A methodology is proposed for measuring and analysing the whole displacement field based on the contour of the four pelvic organs: the vagina, bladder, rectum and uterus. A targeted analysis of pelvic mobility can be applied in the normal, hypermobility and hypomobility context. The quantification of pelvic mobility in normal conditions allows localising fascia or ligaments involved in the static of pelvic organs. In pathological situations such as prolapse, it helps localise a suspension structure weakness. In a context of hypomobility such as deep pelvic endometriosis, it should help localise pathologic areas to provide more relevant diagnosis and treatment. When combined with conventional radiology, this analysis protocol can be applied to the diagnosis and assessment of complex pelvic pathologies to help define the most suitable surgery. Moreover, these experimental results obtained in normal and pathological cases will help build and validate a better mechanical finite element model of the pelvic system

“…Biomechanical numerical simulation could offer indirect characterization of pelvic organs mechanical impairment and guide surgical intervention, anticipating patients recovery. Based on shape descriptors and anatomical references approximation, comparison criteria between simulation sequence and 2D midsagittal dynamic MRI of a same patient was proposed to validate and enhance a physical model [17]. 2D dynamic data are not sufficient to depict realistic 3D biomechanical models.…”
