穿透性伤害通常是由爆炸装置造成的。四肢，尤其是腿部，是最常受感染的身体部位，感染风险高，恢复缓慢，有截肢的危险。本研究的目的是量化金属碎片模拟射弹（FSP）对胫骨前内侧、后部和外侧骨折的风险。采用气枪系统和0.78 g圆柱形FSP对羊胫骨模型进行试验。随后，利用皮质厚度比对动物研究结果进行缩放以获得人类胫骨骨折风险曲线。在评估骨折风险时也考虑了周围软组织的厚度。胫骨外侧皮质最容易发生骨折，EF1+、EF2+、EF3+和EF4+骨折类型（根据改进的Winquist-Hansen分类）的50%风险下，其冲击速度分别为174、190、212和282 m/s。本研究结果将用于提高弹丸侵彻预测模型的保真度。
Penetrating injuries are commonly inflicted in attacks with explosive devices. The extremities, and especially the leg, are the most commonly affected body areas, presenting high risk of infection, slow recovery, and threat of amputation. The aim of this study was to quantify the risk of fracture to the anteromedial, posterior, and lateral aspects of the tibia from a metal fragment-simulating projectile (FSP). A gas gun system and a 0.78-g cylindrical FSP were employed to perform tests on an ovine tibia model. The results from the animal study were subsequently scaled to obtain fracture-risk curves for the human tibia using the cortical thickness ratio. The thickness of the surrounding soft tissue was also taken into account when assessing fracture risk. The lateral cortex of the tibia was found to be most susceptible to fracture, whose impact velocity at 50% risk of EF1+, EF2+, EF3+, and EF4+ fracture types – according to the modified Winquist-Hansen classification – were 174, 190, 212, and 282 m/s, respectively. The findings of this study will be used to increase the fidelity of predictive models of projectile penetration.
