Analysis of dismemberment trauma aims at identifying characteristics of false starts and complete sections in order to identify the class of saw. Nevertheless, determination of the individual weapon remains a challenging task. We attempted to determine the unique characteristics of different blades within the same class of saws using epifluorescence macroscopy, a non-invasive technique, in order to establish an individual injury profile. Two hacksaw blades of identical characteristics (size, set and shape of the teeth) were used to create false starts and complete sections on partially defleshed pig bones. These wounds were then analyzed using epifluorescence macroscopy. Bone lesion analysis determined characteristics that were common to both blades, corresponding to size, raker set and ripcut shape. The data collected made it possible to reconstruct the trauma. Furthermore, we highlighted specific characteristics of each blade in both false starts and complete sections. These characteristics mainly related to the shape and profile of the kerf, the consistency of cut and type of fluorescent wall striations. The sum of the information collected in examination of dismemberment wounds can identify, through comparative analysis, the individual weapon responsible for the imprints observed on the bones.
对肢解创伤的分析旨在识别起始错误和完整截面的特征，以便确定锯子的类别。然而，确定具体使用的凶器仍然是一项具有挑战性的任务。我们试图使用落射荧光宏观检查法（一种非侵入性技术）来确定同一类锯子中不同刀片的独特特征，以便建立个体损伤特征。使用两把具有相同特征（尺寸、锯齿间距和形状）的钢锯条在部分去皮的猪骨上制造起始错误和完整截面。然后使用落射荧光宏观检查法对这些伤口进行分析。骨损伤分析确定了两把锯条共有的特征，这些特征与尺寸、锯路宽度和锯割形状相对应。收集到的数据使重建创伤成为可能。此外，我们还突出了每把锯条在起始错误和完整截面中的特定特征。这些特征主要与锯口的形状和轮廓、切割的一致性以及荧光壁条纹的类型有关。通过比较分析，在肢解伤口检查中收集到的信息总和能够识别在骨头上留下印记的具体凶器。
