Prone Anterior Drawer Test
The Prone Anterior Drawer Test of the ankle is an orthopaedic test used to assess the integrity of the lateral collateral ligaments of the ankle viz: anterior talofibular, calcaneofibular and posterior talofibular ligaments. It is an alternative to the conventional ways of performing the anterior drawer test of the ankle.
Patient is placed in prone position with the foot and ankle extending beyond the end of the plinth. With one hand, the examiner stabilizes the talofibular joint and with the other hand, holds the patient's foot around the heel and then applies an anterior force steadily through it. Translation is compared on both sides.
The test is positive when there is an excessive anterior movement of the foot and a dimpling of the skin on both sides of the Achilles tendon when compared to the uninjured foot. A positive test also implies a rupture of the anterior talofibular joint.
No psychometric properties have been reported for this ankle test.
