What is the most common ligament disruption involved in lateral ankle sprains?

The anterior talofibular ligament (ATFL) is the most commonly involved ligament in lateral ankle sprains. This ligament is located on the outer side of the ankle and plays a significant role in stabilizing the joint, especially during movements that cause inversion, which is the most common mechanism of injury for ankle sprains.

When a person rolls their ankle, the ATFL is typically the first ligament to be stressed and may become torn. This is due to the ligament's anatomical position and its function in limiting excessive inversion and maintaining proper alignment of the talus bone within the ankle joint.

Understanding the role of the ATFL in lateral ankle sprains is crucial for diagnosing and treating these injuries effectively. Rehabilitation programs often focus on strengthening and stabilizing the structures surrounding the ATFL to prevent re-injury and ensure proper recovery.
