The aim of the study was to determine the external load during the standing phase on one limb during walking, based on the finite element method (FEM). It is important for the development and implantation of fixation implants in the case of injury to the anterior segment of the pelvis and also for determining the load during healing.

We compared the obtained findings with the images obtained during MRI. The results showed that the greatest stress in the area of the symphysis is at the edge of the lower (arch) pubic ligament.

The greatest deformation of the symphysis was localized in the lower part, where the primary cavity of the symphysis is visible on MRI, which arises in early childhood, probably at the time of the transition to bipedal walking. The analysis of the result in accordance with the clinical experience proved that the fixation bridging the symphysis is an obstacle to the normal function of the symphysis, therefore it is advisable to remove this implant in young people after the healing of the pelvic fracture.
