Data for: Anatomical Study of the Compositions and Internal Connections of the Chiasma Plantare (Master Knot of Henry): Exploring its Possible Clinical Impact

We have carefully recorded data including the Cross-sectional Sectional area Area of FHL and FDL, the connections between the FHL and FDL and the structure of their fibers connecting with the QP, as well as the branches of these three tendons to each of the five long flexor tendons, which were analyzed and described, along with the shape of the QP. Furthermore, the present results were used to integrate and classify the composition of the chiasma plantare and the connections between the FHL and FDL. Meanwhile, the flexion actions of the toes were deduced and classified according to the toe dedication of each long flexor tendon comprehensively controlled by the assembly of the FHL, FDL and QP.

本研究已精准采集并记录了相关数据，内容涵盖拇长屈肌（Flexor Hallucis Longus, FHL）与趾长屈肌（Flexor Digitorum Longus, FDL）的横截面积、二者之间的连接结构，以及它们与足底方肌（Quadratus Plantae, QP）的纤维连接构造，同时记录了这三条肌腱分别对五根长屈肌腱的分支分布情况，并对上述内容进行了详细分析与描述。此外，本研究还对足底方肌的形态特征进行了观测与记录。进一步地，本研究基于上述结果，对跖侧腱交叉（chiasma plantare）的组成结构以及拇长屈肌与趾长屈肌之间的连接关系进行了整合与分类。与此同时，结合由拇长屈肌、趾长屈肌与足底方肌共同构成的复合体全面支配的各长屈肌腱的脚趾附着位点，本研究推导并分类了各脚趾的屈曲动作机制。
