在爆炸和弹道撞击中看到的高能创伤事件对人体造成严重损害。损伤通常很复杂，确切的机制还没有完全了解。二次爆炸伤，有效的弹道创伤，四肢是常见的报告，特别是胫骨。本研究的目的是量化的影响，如弹丸质量，速度和影响的位置上的腿的伤害阈值的参数。将骨置于生物明胶组织模拟物中;使用32 mm口径气枪以100 - 360 m/s的速度发射质量为0.78 ± 0.01 g的碳钢射弹。 记录了穿透深度和撞击速度。通过预压缩样本再现站立姿势下骨上的载荷。初步结果表明，326 ± 5 m/s的冲击速度大约是猪股骨穿透骨的阈值。
High energy trauma events as seen in explosions and ballistic impact cause severe damage to the human body. The injuries are generally complex and the precise mechanism is not fully understood. Secondary blast injuries, effectively ballistic traumas, to the extremities are commonly reported, especially to the tibia. The aim of this study is to quantify the effect of parameters such as projectile mass, velocity, and impact location on the injury threshold of the leg. The bone was set in biofidelic gelatin tissue simulant; a 32-mm-bore gas gun was used to launch a carbon-steel projectile of 0.78 ± 0.01 g in mass at velocity 100 to 360 m/s. Penetration depth and impact velocity were recorded. The loading on the bone, in the standing posture was reproduced by pre-compressing the sample. Preliminary results showed that the impact velocity of 326 ± 5 m/s is approximately the threshold for the through-bone penetration of the porcine femur.
