What is the most common ankle sprain?

• A. Anterior Talofibular ligament
• B. Calcaneofibular ligament
• C. Posterior talofibular ligament
• D. Deltoid ligament

Answer: (A)

An ankle sprain most often involves the lateral ligaments, and the anterior talofibular ligament is the first and most commonly injured structure in inversion injuries with plantarflexion. The ATFL is relatively thin and lie toward the front of the ankle, so when the foot twists inward and upward at the toes, this ligament bears the brunt of the stress and tends to tear first. That’s why it’s the most common sprain you’ll see. If the force is greater, the calcaneofibular ligament may also be sprained, but the deltoid ligament on the inner side is involved far less often, since eversion injuries are less common. The posterior talofibular ligament is even less frequently injured in typical inversion sprains.
