Ankle Posterior Drawer Test

The posterior drawer test is a physical examination that assesses the integrity of the posterior talofibular ligament (PTFL) in the ankle, often used to diagnose ligamentous laxity or rupture.

To perform a posterior drawer test, position the patient supine, stabilize the tibia and fibula, and apply a posterior force on the calcaneus while plantar flexing the foot.

A positive test of the posterior drawer is when there is an excessive posterior translation or a sulcus sign, suggesting ligamentous laxity or rupture in the posterior talofibular ligament.
