What does the Ankle Anterior Drawer Test assess?

The Ankle Anterior Drawer Test is specifically designed to assess the integrity of the anterior talofibular ligament (ATFL), which is a crucial ligament in the ankle. This test is performed by stabilizing the lower leg and pulling the heel forward while keeping the foot positioned in slight plantarflexion. If the ATFL is compromised, there will be increased anterior translation of the talus relative to the tibia, indicating instability in that area.

The ATFL is commonly injured during activities that involve ankle sprains, particularly when the ankle rolls outward. By focusing on the anterior drawer movement, this test directly evaluates the ligament's ability to resist that force, making it an essential tool for clinicians when determining the severity of an ankle injury.

Evaluating the other options helps clarify why they are not correct. Medial instability pertains to injuries concerning the medial ligaments, such as the deltoid ligament. The deltoid ligament's stability cannot be specifically assessed with the anterior drawer test, as it targets the anterior aspect of the ankle. Syndesmosis injuries involve the connection between the tibia and fibula, not the ATFL specifically. Therefore, the Ankle Anterior Drawer Test is primarily indicative of ATFL instability, making that the most
