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.
前距腓韧带和跟腓韧带是最常受伤的踝关节韧带。本研究旨在探讨双重纤维前距腓韧带和跟腓韧带是否与这两条韧带之间的连接以及与非韧带结构的连接有关。对 198 例踝关节磁共振成像检查进行了回顾性再评估。研究了双重纤维前距腓韧带和跟腓韧带与上腓侧支持带、腓骨肌腱鞘、胫腓侧副韧带和下伸肌支持带之间的相关性。研究了前距腓韧带和跟腓韧带的直径与连接之间的关系。大多数连接在前距腓韧带和跟腓韧带的一组双重纤维束中可见。最常见的是前距腓韧带和跟腓韧带之间的连接（74.7%）。在前距腓韧带与腓骨肌腱鞘之间（p < 0.001）以及跟腓韧带与后胫腓侧副韧带（p < 0.05）、上腓侧支持带（p < 0.001）和腓骨肌腱鞘（p < 0.001）的连接组中，单束和双束韧带组之间存在统计学显著差异。前距腓韧带和跟腓韧带厚度（p < 0.001）、前距腓韧带腓骨插入部直径（p < 0.001）、跟腓韧带跟骨附着部直径（p < 0.05）和胫距角（p < 0.01）之间存在统计学差异。双重纤维前距腓韧带和跟腓韧带束的存在与邻近结构的连接相关。
