In addition to loose connective tissue, fat and blood vessels, the sinus and canalis tarsi also contain the capsules for the intertarsal joints as well as several varyingly stable tracts of fibers which present themselves in varying planes and directions but are nevertheless in a discernible arrangement to one another. This arrangement of fibers was studied on the feet of 40 adults whereby five distinct and clearly definable bundles could be regularly dissected. Starting from the lateral side and going medialis of the retinaculum mm. extensorum inferius, also a lig. talocalcaneum obliquum and a lig. canalis tarsi. Microscopically, fibrocartilage is evidenced in the ligaments and retinacula near their points of attachment to the bone. The ligaments lying lateral to the axis of movements for the talocalcaneal joint restrain the inversion while the medially lying lig. canalis tarsi prevents the eversion.
除了疏松结缔组织、脂肪和血管外，跗窦和跗管还包含跗间关节的关节囊以及几条稳定性各异的纤维束，这些纤维束呈现在不同的平面和方向上，但彼此之间仍有可辨别的排列方式。在40名成年人的足部研究了这种纤维排列，据此可以常规解剖出五个不同且清晰可辨的束。从下伸肌支持带的外侧开始向内，还有一条距跟斜韧带和一条跗管韧带。在显微镜下，在韧带和支持带靠近其附着于骨的部位可发现纤维软骨。位于距跟关节运动轴外侧的韧带限制内翻，而位于内侧的跗管韧带则防止外翻。
