The purpose of this analysis is to evaluate the effects of burning on hacking trauma inflicted with a cleaver and to assess the diagnostic potential of cleaver marks exposed to fire. Thirty pig forelimbs (radius and ulna) and 30 beef ribs were each subjected to five blows with a cleaver and five cuts with a knife prior to burning in an outdoor fire. Bones were deliberately agitated to ensure maximum cremation and induce fragmentation. Results indicate that hacking weakens bone, making fire-induced fragmentation more likely at the sites of trauma. Chop marks were easily identified on burned bone, their characteristics largely unaffected by cremation.
本分析的目的是评估焚烧对用剁刀造成的砍击创伤的影响,并评估暴露于火中的剁刀痕迹的诊断潜力。在户外焚烧之前,对30个猪前肢(桡骨和尺骨)和30根牛肋骨分别用剁刀击打5次、用刀切割5次。故意搅动骨头以确保最大程度的火化并导致破碎。结果表明,砍击会削弱骨头,使创伤部位更有可能因火而破碎。在烧焦的骨头上很容易识别出砍痕,其特征在很大程度上不受火化的影响。
