RESUMEN
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. Based on the data obtained, models for diagnosing the type of external influence were developed.
