THE PERSPECTIVES OF THE STUDY OF CUTTING AND STABBING DAMAGES CAUSED BY THE KNIFE IMPACT WITH VARIOUS SPINE THICKNESS

Injuries caused by pointed or bladed articles cover the biggest part of all the injuries caused by sharp objects. Last decades of scientific studies in forensic medicine have been dedicated to the questions of forensic medicolegal traumatology due to a steady growth of a number of forensic examinations connected with mechanical injuries. The data about the morphology, mechanism and biomechanical causation of cutting and stabbing damages have been studied over and summarized. There have been found some morphological features of cutting and stabbing damages of osseous tissue appearing according to the theory of material cutting. There have been studied the possibilities of forensic identification of pointed or bladed articles according to the features of injuries on human tissues and clothes. The analysis results of scientific literature show that nowadays a spine of a knife is considered a traumatic part of a blade. In the course of an identification examination of pointed or bladed trace - forming articles a notion a spine zone is used. There has been overviewed an influence on a process of trace-formation of the edges of a knife. However, the morphology of pointed or bladed injuries of bones according to the thickness of a blade has not been examined deeply. Aiming to improve forensic research of injuries of flat bones (os planum) caused by pointed or bladed articles on the base of a complex of morphological features, it is needed to organize experimental researches using a cadaveric material.
