Final answer:
The anterior talofibular ligament is the most commonly injured during an ankle sprain, followed by the calcaneofibular ligament, and then the posterior talofibular ligament in severe cases. The RICE technique is recommended for treatment, with surgery required for more severe injuries.
Step-by-step explanation:
The most common ligaments affected by an ankle sprain are involved during an inversion ankle sprain injury. In this type of injury, three ligaments that resist excessive inversion of the foot may be damaged. The sequence of ligament injuries starts with the anterior talofibular ligament, which is the most commonly injured, followed by the calcaneofibular ligament. In more severe cases, the posterior talofibular ligament may also be injured. These injuries can range from stretching to complete tears. When treating most ankle sprains, the RICE technique, which includes Rest, Ice, Compression, and Elevation, is often recommended. More serious cases that involve ligament tears or bone fractures may necessitate surgical intervention.
