38. Sprain of the ankle joint results from an injury to

(a) Deltoid ligament
(b) Spring ligament
(c) Posterior talofibular ligament
(d) Anterior talofibular ligament

On the lateral (outside) of the ankle is a complex of three ligaments. These three ligaments provide stability by attaching the lateral malleolus to the bones below the ankle joint (talus and calcaneus). They are the:

1. anterior talo-fibular ligament (goes from the talus to the fibula)

2. calcaneo-fibular ligament (goes from the calcaneus to the fibula)

3. posterior talo-fibular ligament (goes from the talus to the fibula).

The lateral ligaments are the most commonly injured. On the lateral side, the ligaments are typically damaged in a direction that goes from the front to the back, with the most severe injury being in the front (anterior) and the least severe being in the back (posterior). Therefore, the most commonly damaged ligament is the anterior talo-fibular ligament and the least commonly damaged is the posterior talofibular ligament.
