Ankle sprains are the most frequent sport related injuries with involvement of the lateral collateral ligament complex occurring in 85% of cases. Isolated anterior talofibular ligament injury is by far the commonest followed by combined anterior talofibular and calcaneofibular ligament strain. The posterior talofibular ligament is the strongest component of the lateral collateral ligament complex and is injured in severe ankle injury along with the other lateral collateral ligaments. While isolated calcaneofibular ligament strain has been reported, calcaneofibular ligament and posterior talofibular ligament strains with an intact anterior talofibular ligament are rare and reported in cadaveric studies. We present a case of radiologically diagnosed calcaneofibular ligament and posterior talofibular ligament injury and will discuss the anatomy, stress radiography, and magnetic resonance image findings and the mechanism of this particular injury.
踝关节扭伤是最常见的运动相关损伤，其中外侧副韧带复合体受累占 85%。单纯的前距腓韧带损伤最为常见，其次是前距腓和跟腓联合韧带扭伤。后距腓韧带是外侧副韧带复合体中最强的组成部分，在严重的踝关节损伤时与其他外侧副韧带一起受伤。虽然有报道称孤立的跟腓韧带扭伤，但跟腓和后距腓韧带扭伤而前距腓韧带完整的情况很少见，并且在尸体研究中有所报道。我们报告了一例经放射学诊断的跟腓和后距腓韧带损伤，并将讨论该特定损伤的解剖、应力量线摄影和磁共振成像表现以及机制。
