Experience in using finite element analysis for predicting and diagnosing spleen injuries

The study aimed to study and assess the possibility of establishing the localization and nature of spleen injuries by using finite element analysis when simulating impact in the left hypochondrium. The mechanism of the formation of organ damage is considered. The possible localization and nature of the predicted damage to the spleen, depending on the power load, were established. Critical stresses, which indicate the possibility of rupture, arise on the spleen ligaments when the impact is over 1000 N and on the vascular pedicle - over 2000 N. At lower load indicators, non - critical stresses appear in these areas, which make it possible to predict the formation of subcapsular hemorrhages. Crushing and fragmentation of an organ occur when the impact is over 4000 N, which corresponds to the force of the blow of a professional boxer. Law enforcement agencies can use the results obtained in modeling the spleen injury to establish her injury.
