Which ligaments are injured during ankle inversion?
The lateral ankle ligaments are injured during ankle inversion. The lateral ankle ligaments are composed of the anterior talofibular ligament, calcaneofibular ligament, and posterior talofibular ligament. The anterior talofibular ligament is the first ligament to tear during ankle inversion and is therefore the most commonly injured ligament. A more severe ankle inversion will next result in a calcaneofibular ligament tear followed by a posterior talofibular ligament tear, although injury involving all three ligaments is rare.
