The discrimination of falls from homicidal blows in blunt head injuries is a common but difficult problem in both forensic anthropology and pathology. Three criteria have been previously proposed for this distinction: the hat brim line rule, side lateralization of fractures, and number of lacerations. The aim of the present study was to achieve a better distinction rate by combining those criteria and assess the predictability of these combined criteria tools. Over a 6-year period, a total of 114 cases (92 males and 22 females) were studied: 21 cases of downstairs falls, 29 cases of falls from one's own height, and 64 cases of head trauma by a blunt weapon. The results revealed predictability rates varying from 62.5 to 83.3% for criteria pointing towards a fall. As for combined criteria in favor of a blow, the assumption was accurate in all cases (100%).
在法医人类学和病理学中，区分钝器头部损伤中的跌倒伤和他杀打击伤是一个常见但困难的问题。此前已提出三个区分标准：帽檐线规则、骨折的侧别定位以及撕裂伤数量。本研究的目的是通过结合这些标准实现更高的区分率，并评估这些综合标准工具的可预测性。在6年期间，共研究了114例病例（92例男性和22例女性）：21例下楼跌倒、29例从自身高度跌倒以及64例钝器头部外伤。结果显示，指向跌倒的标准的可预测率在62.5%至83.3%之间。至于支持打击伤的综合标准，在所有病例中假设均准确无误（100%）。
