The aim of the work is to establish the possibility of mathematical modeling of the injuries formation in the mobile and fixed spleen under shock impact to the region of the left middle axillary line of the chest. A spleen injury with a pinched and movable vascular pedicle was simulated, for which were created two models in three-dimensional virtual space — the spleen model and the rib-sternum segment model. Differences in the concentration and localization of stresses arising on the spleen were noted in cases of fixed and non-fixed vascular pedicle. It was found that under the same conditions of injury (place of application and direction of the injury, impact force), «critical» stresses that can lead to ruptures occur on the spleen, which has a fixed vascular pedicle.
