Posterior Talofibular Ligament 

- Discussion:
    - posterior talofibular ligament arises from the nonarticular surface of posteromedial Fibula & inserts onto lateral tubercle of talus;
    - it is strongest of the lateral ligaments;
    - prevents posterior and rotatory subluxation of the talus;
    - fibers are oriented horizontally, & tensed only in extreme dorsiflexion;
    - posterior talofibular ligament is under tension and can either rupture or avulse the posterolateral corner of tibia  (Volkmann's triangle);
    - transverse tibiofibular ligament is often considered part of posterior talofibular ligament complex and acts to deepen posterior aspect of ankle joint
