This study aimed to clarify the relationship between the joint and ligament structures of the subtalar joint and degeneration of the subtalar articular facet. We examined 50 feet from 25 Japanese cadavers. The number of articular facets, joint congruence, and intersecting angles were measured for the joint structure of the subtalar joint, and the footprint areas of the ligament attachments of the cervical ligament, interosseous talocalcaneal ligament (ITCL), and anterior capsular ligament were measured for the ligament structure. Additionally, subtalar joint facets were classified into Degeneration (+) and (-) groups according to degeneration of the talus and calcaneus. No significant relationship was identified between the joint structure of the subtalar joint and degeneration of the subtalar articular facet. In contrast, footprint area of the ITCL was significantly higher in the Degeneration (+) group than in the Degeneration (-) group for the subtalar joint facet. These results suggest that the joint structure of the subtalar joint may not affect degeneration of the subtalar articular facet. Degeneration of the subtalar articular facet may be related to the size of the ITCL.
本研究旨在阐明跗骨间关节的关节和韧带结构与跗骨关节面退变之间的关系。我们检查了 25 具日本尸体的 50 只脚。测量了跗骨间关节的关节结构的关节面数量、关节吻合度和相交角度，以及颈韧带、骨间跟距韧带 (ITCL) 和前囊韧带附着处的足迹面积。此外，根据距骨和跟骨的退变将跗骨关节面分为退变 (+) 和 (-) 组。跗骨间关节的关节结构与跗骨关节面退变之间没有明显的关系。相比之下，在跗骨关节面退变 (+) 组中，ITCL 的足迹面积明显高于退变 (-) 组。这些结果表明，跗骨间关节的关节结构可能不会影响跗骨关节面的退变。跗骨关节面的退变可能与 ITCL 的大小有关。
