The main objective of the study was to determine the type of macroscopic trauma created by a flat-tipped and a cross-tipped screwdriver. The second objective was to determine if the trauma inflicted by the two screwdrivers could be macroscopically differentiated. Three tests were conducted, each by a male volunteer. Each test consisted of 12 samples of fleshed pig ribs; six were stabbed with a flat-tipped screwdriver and the remaining six with a cross-tipped screwdriver (Phillips). Each sample received 15 stab wounds during the process. The stabbings were conducted at perpendicular and oblique angles, with fabric variables being utilized. Results illustrate two main categories of macroscopic skeletal trauma, fractures, and puncture wounds. By studying the macroscopic appearance in tandem with differing trauma frequencies, these two screwdriver types can be differentiated.
该研究的主要目的是确定平头螺丝刀和十字螺丝刀造成的宏观创伤类型。第二个目的是确定这两种螺丝刀造成的创伤在宏观上是否可以区分。进行了三项测试，每项测试由一名男性志愿者完成。每次测试包括12个带肉的猪肋骨样本；其中六个用平头螺丝刀刺伤，其余六个用十字螺丝刀（菲利普斯螺丝刀）刺伤。在这个过程中，每个样本都被刺了15处伤口。刺伤以垂直和倾斜角度进行，并使用了不同的织物变量。结果表明宏观骨骼创伤主要有两类，即骨折和刺伤。通过结合不同的创伤频率研究宏观外观，可以区分这两种螺丝刀类型。
