When an ankle is injured from twisting in towards the other foot, called an inversion injury, most commonly the anterior talofibular ligament is stretched or torn. If the two other primary ligaments on the outside of the ankle (the posterior talofibular ligament and the calcaneofibular ligament) are also injured the primary bone of the ankle, the talus, can be displaced from beneath the tibia, and the ankle "shucks" out of joint. A physician or trainer examining the ankle soon after injury can compare the amount of "shuck" to the opposite ankle and develop a grade for the amount of injury suffered. Usually, if the injury is limited to one ligament, the instability is less. If all three are involved , the ankle is more unstable. The nerve supply to injured ligaments can also be injured. The nerves provide "proprioception" or position sense, in effect telling the brain where the foot is in space. In the healing process, it is critical to re-train the healing ligaments to regain the neural connections required for a stable ankle. Specific exercises can effectively do this.2
