The specific traumatic mechanism that leads to the formation of the butterfly fragment is debated in literature. The aim of the present study is to analyze the biomechanics of fractures with a "butterfly" fragment, using a software that simulates the movement of the lines of force (and related iso-displacement points) that occur on the bone, when traumatic forces are applied on it. We have shown that the formation of the butterfly fragment derives from the application of three forces (compression, torsion and bending) with the bending force that acts by increasing the curvature of the long bone.
文献中对于导致蝶形碎片形成的具体创伤机制存在争议。本研究的目的是使用一种模拟作用于骨骼上的力的运动（以及相关的等位移点）的软件，分析具有“蝶形”碎片的骨折的生物力学。我们已经表明，蝶形碎片的形成源于三种力（压缩、扭转和弯曲）的作用，其中弯曲力通过增加长骨的曲率起作用。
