[Mathematical modeling of femoral diaphyseal fracture at an acute angle].

The aim of the work is to establish the regularity of the formation femoral diaphysis fracture under an impact action on the anterior surface of the femur at an acute angle. As a result of mathematical modeling, transverse and short oblique, comminuted fractures of the femoral diaphysis were studied. Application of mathematical modeling with final element analysis made it possible to visualize and predict the stresses arising in the trace-perceiving material under the impact action of a blunt solid object.

[Mechanics and morphology of destruction of the diaphysis of long tubular bones of the lower extremities under various types of external influences by blunt solid objects].

The purpose of the study is to develop forensic criteria for determining the mechanisms of fractures of long tubular bones of the lower extremities subjected to dynamic (impact) and static (compression) impacts with blunt objects, in relation to road traffic injury and falling from a height. The morphological characteristics of damages to the long tubular bones of the lower extremities under shock and compression loading of the extremities of biomannequins at various structural levels were studied. Objective morphological qualitative and quantitative criteria for fractures under various types of loading are revealed based on the analysis of the morphological characteristics of a fracture and in the depth of the compact bone layer.
