New Anatomical Structure Described in the Ankle Joint (IMAGE)
Caption
The superior fascicle of the anterior talofibular ligament (1) is an intra-articular non-isometric structure, that is, it relaxes when the foot is on dorsal flexion and it stresses when in plantar flexion. The interior fascicle of the anterior talofibular ligament (2), together with the calcaneofibular ligament (3) and arciform fibbers that unify them, create the new lateral fibulotalocalcanean complex. This is an extra-articular and isometric structure, that is, it is always tense and stabilizes the ankle in any foot position.
