Abstract Background Despite the numerous in-vitro studies on the mechanical properties and simulated injury mechanisms of the anterior talofibular ligament ATFL and calcaneofibular ligament CFL the in-vivo biomechanical behavior of these two ligaments has not yet been described. Methods Apparent length of the ATFL and CFL was measured in four ankles in healthy male subjects between 32 and 45 years of age two left and two right during a dorsiflexionplantarflexion and supination-pronation arc of motion using a combined dual-orthogonal fluoroscopic and magnetic resonance imaging technique. Results The ATFL elongated from the neutral position at - mm to - mm at maximal plantarflexion and shortened significantly from the neutral position to - mm at maximal dorsiflexion p . The CFL .
