Features of damage to the ribs by a blade with a defective tip

Abstract

Stab wounds are a common injury in the practice of a forensic pathologist. Such damage often occurs in domestic conditions, for example, in the kitchen during a quarrel, where knives are always at hand. The young, able-bodied portions of the population are frequent victims, which makes the problem socially significant.
 Knives that have been used for a long time are rarely in perfect condition; operational defects occur on them. For example, repeated sharpening results in the rounding of the tip of the blade. Moreover, during operation, the tip of the blade can bend or even break off. However, before studying the effects of such blades on flat bones, studying the history of this issue, to familiarize with the work of other scientists, is necessary.
 In the literature review, authors of studies on stab-cut injuries focused more on damage to the skin and clothing. Morphological features of skeletal bone injuries and the possibility of identification studies on them until the XXI century were described poorly.
 To improve the forensic medical diagnosis of rib injuries caused by blades with point defects based on the study of a complex of morphological features, experimental studies on cadaveric materials are necessary.
