The human talocalcaneonavicular joint was dissected and structural heterogeneity of their articular faces and associated ligaments were observed. The facies articulatio talaris anterior and media were either separated from each other (separate type), bordered by narrowing (constricted type) or continuous without any border (continuous type). In the separate type, the superficial layer of plantar calcaneonavicular ligament entered the grave between the anterior and middle articular faces. In the constricted type, the superficial layer of plantar calcaneonavicular ligament entered the neck of two articular faces from the medial side, and a part of the calcaneonavicular interosseous talocalcaneo ligament entered the neck from the lateral side. In the continuous type, the deep layer of calcaneonavicular ligament attached to the base of these articular faces. Furthermore, we observed mobility of the talotarsal joint, and found tendencies that feet of the separate type showed the smallest mobility and those of continuous type the largest mobility. It was concluded that the structure of the articular faces of the talocalcaneonavicular joint were variable and were correlated not only with the structure of their associated ligaments, but also with their mobility.
对人距跟舟关节进行解剖，并观察其关节面和相关韧带的结构异质性。距骨前关节面和中关节面要么相互分离（分离型），要么以变窄为界（缩窄型），要么连续无边界（连续型）。在分离型中，跟舟足底韧带浅层进入前后关节面之间的沟内。在缩窄型中，跟舟足底韧带浅层从内侧进入两个关节面的颈部，距跟舟骨间韧带的一部分从外侧进入颈部。在连续型中，跟舟韧带深层附着于这些关节面的底部。此外，我们观察了跗骨间关节的活动度，发现分离型足的活动度最小，连续型足的活动度最大。得出结论，距跟舟关节关节面的结构是可变的，不仅与其相关韧带的结构有关，还与其活动度有关。
