The anterior talofibular ligament and the calcaneofibular ligament are the most commonly injured ankle ligaments. This study aimed to investigate if the double fascicular anterior talofibular ligament and the calcaneofibular ligament are associated with the presence of interconnections between those two ligaments and connections with non-ligamentous structures. A retrospective re-evaluation of 198 magnetic resonance imaging examinations of the ankle joint was conducted. The correlation between the double fascicular anterior talofibular ligament and calcaneofibular ligament and connections with the superior peroneal retinaculum, the peroneal tendon sheath, the tibiofibular ligaments, and the inferior extensor retinaculum was studied. The relationships between the anterior talofibular ligament’s and the calcaneofibular ligament’s diameters with the presence of connections were investigated. Most of the connections were visible in a group of double fascicular ligaments. Most often, one was between the anterior talofibular ligament and calcaneofibular ligament (74.7%). Statistically significant differences between groups of single and double fascicular ligaments were visible in groups of connections between the anterior talofibular ligament and the peroneal tendon sheath (p < 0.001) as well as the calcaneofibular ligament and the posterior tibiofibular ligament (p < 0.05), superior peroneal retinaculum (p < 0.001), and peroneal tendon sheath (p < 0.001). Differences between the thickness of the anterior talofibular ligament and the calcaneofibular ligament (p < 0.001), the diameter of the fibular insertion of the anterior talofibular ligament (p < 0.001), the diameter of calcaneal attachment of the calcaneofibular ligament (p < 0.05), and tibiocalcaneal angle (p < 0.01) were statistically significant. The presence of the double fascicular anterior talofibular ligament and the calcaneofibular ligament fascicles correlate with connections to adjacent structures.

距前腓韧带和跟腓韧带是最常见的踝关节韧带损伤。这项研究旨在调查双束前足前韧带和跟腓韧带是否与这两个韧带之间的相互连接以及与非韧带结构的连接有关。对踝关节的198次磁共振成像检查进行回顾性重新评估。研究了双束状前胫腓韧带和跟腓韧带之间的相关性，以及与腓骨上视网膜，腓骨腱鞘，胫腓韧带和下伸肌视网膜的连接。研究了存在连接处的前腓韧带和跟腓韧带直径之间的关系。大多数连接在一组双束状韧带中可见。最常见的是在前胫腓韧带和跟腓韧带之间（74.7％）。在前胫腓韧带和腓腱鞘之间的连接组中，单束和双束束韧带组之间的统计学差异显着（p  <0.001）以及跟腓韧带和后胫腓韧带（p  <0.05），腓骨上视网膜（p  <0.001）和腓腱鞘（p  <0.001）。的距腓前韧带的厚度和跟腓韧带之间的差异（p  <0.001），在距腓前韧带（的腓骨插入的直径p  <0.001），跟腓韧带的跟骨附着的直径（p  <0.05）和胫骨跟骨角（p <0.01）有统计学意义。束状双前胫腓韧带和跟腓韧带双束韧带的存在与相邻结构的连接相关。
