Simulation of normal pelvic mobilities in building an MRI-validated biomechanical model.
OBJECTIVE
Three-dimensional modeling of feminine pelvic mobility is difficult because the sustaining system is not well understood and ligaments are especially difficult to identify on imaging.


METHODS
We built a 3-D numerical model of the pelvic cavity, based on magnetic resonance (MR) images and knowledge about anatomy and validated it systematically.


RESULTS
The quantitative results of this model allow for the non-destructive localization of the structures involved in pelvic statics. With a better configuration of the functional pelvis and topological criteria, we can obtain a coherent anatomical and functional model.


CONCLUSIONS
This model is the first step in developing a tool to localize and characterize pelvic imbalance in patients.
