Stress distribution in pelvic floor structures depending on real fetus head molding and trajectory during vaginal delivery
Original language description
Pelvic floor dysfunctions are very often associated with injuries of m. levator ani (MLA) during vaginal delivery. The aim of this work was to analyze the stress distribution in MLA during vaginal delivery using the new FE model and a deformable fetal head respecting dynamic MRI. The detal head includes sutures, fontanelles and 7 rigid bones. The trajectories of bones are based on real-time dynamic MRI recorded during vaginal delivery occuring over 2 contractions. Two models were compared: (1) the rigid head and (2) the deformable one. The results show that the deformable head leads to stress reduction of almost 20% - (1) in the left attachment to the pelvis - 54.41 MPa and (2) in lower part in the middle - 47 MPa.
