本研究对胫腓骨前下韧带（AITFL）的下束进行分类，为阐明踝关节前外侧撞击机制提供基础信息，并对各类型的形态学特征进行比较，以澄清。这次调查检查了距52具尸体100英尺的地方。根据有无下肌束及与下肌束的位置关系，将下肌束分为四种类型。测量了AITFL的形态特征，包括纤维束长度、纤维束宽度、纤维束角度和关节水平之间的距离。在15英尺（15%）处发现明显独立的AITFL下束。基于AITFL分类的差异，形态学特征没有显著差异。因此，这些研究结果表明，下肌束的存在与否以及下肌束与下肌束位置关系的差异，都不太可能参与踝关节背屈时的撞击。
In this study, the inferior fascicle of the anterior inferior tibiofibular ligament (AITFL) was classified to provide basic information to help elucidate the mechanism of ankle joint anterolateral impingement, and the morphological features of each type were compared for the purpose of clarification. This investigation examined 100 feet from 52 cadavers. The AITFL was classified into four types according to the presence or absence of the inferior fascicle and the positional relationship between the AITFL and the inferior fascicle of the AITFL. The morphological features of the AITFL that were measured included the fibre bundle length, fibre bundle width, fibre bundle angle, and the distance between the joint levels. A distinct, independent inferior fascicle of the AITFL was identified in 15 feet (15%). There were no significant differences in the morphological features based on differences in the AITFL classification. Therefore, these findings suggest that the presence or absence of the inferior fascicle and the difference in the positional relationship between the AITFL and the inferior fascicle of the AITFL are less likely to be involved in impingement during ankle dorsiflexion.
