穿透性爆炸碎片是部署到阿富汗的英国服务人员颈部受伤的最常见原因。对这些碎片的分析将使未来的弹道防护材料能够用适当的射弹进行测试。然而，只有少量从颈部切除的碎片可用于分析，它们可能不具有代表性。我们分析了连续110名英国士兵的颈部被爆炸碎片炸伤的计算机断层扫描（CT）。碎片根据形状分类，其尺寸用于估计体积和质量。然后将这些计算结果与使用一般线性模型的切除片段的实际测量结果进行比较。最常见的两种形状是圆柱形（52%）和球形（21%）。已知和估计的质量无显著差异（p = 0.64）。0.49 g的碎片模拟射弹代表85%的碎片保留在颈部。CT可以准确地描绘碎片的形状和质量，这增加了可以从中设计最合适的模拟弹丸的数量。我们认为，这一方法应适用于留在身体其他部位的碎片，以便能够就用于保护军人的弹道材料的测试提出更广泛的建议。皇冠版权所有（C）2013由爱思唯尔有限公司代表英国口腔颌面外科医生协会出版。All rights reserved.
Penetrating explosive fragments are the most common cause of neck injuries sustained by UK service personnel deployed to Afghanistan. Analysis of these fragments will enable future ballistic protective materials to be tested with appropriate projectiles. However, only a small number of fragments excised from the neck have been available for analysis and they are potentially unrepresentative. We analysed computed tomograms (CTs) of 110 consecutive UK soldiers whose necks were wounded by explosive fragments. Fragments were classified according to shape, and their dimensions used to estimate volume and mass. These calculations were then compared with the actual measurements of the excised fragments using a general linear model. The 2 most common shapes were cylinders (52%) and spheres (21%). Known and estimated masses were not significantly different (p = 0.64). A fragment-simulating projectile of 0.49 g represented 85% of fragments retained in the neck. CT can accurately delineate the shape and mass of fragments, which increases the number from which the most appropriate simulated projectile can be designed. We think that this methodology should be applied to fragments retained in other parts of the body to enable broader recommendations to be made regarding the testing of ballistic materials used to protect service personnel.
