A second mechanism for ankle injury is illustrated on this page. In this instance, the foot is everted, then a force is applied on the medial aspect of the ankle. The resulting effect is to twist the talus outward, placing increasing stress on the front-most elements of the deltoid ligament. As the applied force increases, the twisting of the talus forces the mortise formed by the distal tibia and fibula to open, straining the anterior inferior tibiofibular ligament on the opposite side.
