Forensic diagnosis of the direction of traumatic effects in blunt spleen injury

Since the spleen takes the second place after the liver in terms of the frequency of injury, forensic experts often encounter injuries of this organ both in the study of corpses and in the examination of living persons. In the literature there is a large amount of scientific data relating to the establishment of the mechanism of formation of spleen injury. At the same time, there are no data in the scientific literature on the mechanism of formation of damage to the spleen with the tangential direction of the traumatic effect (oblique impact). In the present study, the method of finite element analysis of the distribution of deformations and stresses on the surfaces of the spleen was used to predict the destruction of the spleen tissue characteristic of perpendicular and oblique shock effects. The obtained data can be used in practice by forensic experts in deciding on the direction of the traumatic effect in a closed blunt spleen injury.
