This study examines primary (resulting from blast wave) and secondary (resulting from disintegrated, penetrating fragments) blast trauma to the skeleton. Eleven pigs were exposed to semi-controlled blast events of varying explosive type, charge size, and distance, including some cases with shrapnel. Skeletal trauma was found to be extensive, presenting as complex, comminuted fractures with numerous small, displaced bone splinters and fragments. Traumatic amputation of the limbs and cranium was also observed. Fractures were concentrated in areas nearer the blast, but there was generally no identifiable point of impact. Fractures were more random in appearance and widespread than those typically associated with gunshot or blunt force injury events. These patterns appear to be uniquely associated with blast trauma and may therefore assist forensic anthropologists and other forensic examiners in the interpretation of skeletal trauma by enabling them to differentiate between blast trauma and trauma resulting from some other cause.
本研究考察了骨骼的原发性（由冲击波导致）和继发性（由破碎、穿透性碎片导致）爆炸伤。11头猪暴露于不同炸药类型、装药大小和距离的半控制爆炸事件中，包括一些有弹片的情况。发现骨骼创伤广泛，表现为复杂的粉碎性骨折，伴有大量小的、移位的骨碎片。还观察到肢体和颅骨的创伤性截肢。骨折集中在离爆炸较近的区域，但通常没有可识别的撞击点。骨折在外观上比典型的枪伤或钝器伤事件更随机、更广泛。这些模式似乎与爆炸伤有独特关联，因此可能有助于法医人类学家和其他法医通过使他们能够区分爆炸伤和其他原因导致的创伤，来解读骨骼创伤。
