The assessment of fractures is a key issue in forensic anthropology; however, very few studies deal with the features of fractures due to explosion in comparison with other traumatic injuries. This study focuses on fractures resulting from blast trauma and two types of blunt force trauma (manual compression and running over), applied to corpses of pigs; 163 osteons were examined within forty fractures by the transmission light microscopy. Blast lesions showed a higher percentage of fracture lines through the Haversian canal, whereas in other types of trauma, the fractures went across the inner lamellae. Significant differences between samples hit by blast energy and those runover or manually compressed were observed (p<0.05). The frequency of pattern A is significantly higher in exploded bones than in runover and compressed. Microscopic analysis of the fracture line may provide information about the type of trauma, especially for what concerns blast trauma.
骨折评估是法医人类学中的一个关键问题；然而，与其他创伤性损伤相比，很少有研究涉及爆炸导致的骨折特征。本研究聚焦于猪尸体上因爆炸伤以及两种钝器伤（手动挤压和碾压）造成的骨折；通过透射光显微镜对40处骨折中的163个骨单位进行了检查。爆炸伤显示通过哈弗斯管的骨折线比例更高，而在其他类型的创伤中，骨折穿过内层板。观察到受爆炸能量冲击的样本与被碾压或手动挤压的样本之间存在显著差异（p<0.05）。模式A在爆炸骨骼中的出现频率显著高于被碾压和挤压的骨骼。骨折线的微观分析可以提供有关创伤类型的信息，特别是对于爆炸伤而言。
