What is a common complaint resulting from an ankle inversion?

An ankle inversion occurs when the foot rolls inward, placing stress on the ligaments on the outside of the ankle. This type of movement commonly leads to a lateral ankle sprain, which is the injury that results from these ligaments being overstretched or torn during the inversion.

In lateral ankle sprains, the most frequently injured ligaments are the anterior talofibular ligament and the calcaneofibular ligament. Symptoms typically include pain, swelling, and bruising around the outer ankle, as well as difficulty bearing weight. This makes a lateral ankle sprain the most common complaint after an ankle inversion, highlighting the relationship between the mechanism of injury and the typical outcome.

While other options like plantar fasciitis, Achilles tendon rupture, and fractured malleolus can occur in the lower extremity injured areas, they are not specifically linked to the mechanism of an ankle inversion, and thus would not be the most common complaint in this scenario.
