In the figures on this page, a third mechanism for ankle "sprain" is illustrated. In this situation, the foot is first adducted (rotated to the outside - position 2), then inverted (position 3). This motion shifts the position of the talus relative to the tibia and focuses stress on the forward components of the deltoid ligament and the anterior inferior tibiofibular ligament. With increasing stress, these ligaments are stretched, then torn, potentially even resulting in fracture of the distal fibula.
