Ankle Orthopaedic Test: Prone Anterior Drawer Test

The prone anterior drawer test is a physical examination technique used to assess the stability of the ankle joint, particularly the anterior talofibular ligament. Here are the steps to perform the prone anterior drawer test:

1. Have the patient lie face down on the examination table with their foot hanging off the edge.
2. Grasp the patient's heel with one hand and their foot with the other hand.
3. Stabilize the patient's leg with your forearm.
4. With your other hand, pull the patient's foot forward, as if you were trying to slide the ankle joint forward.
5. Observe the amount of forward movement of the ankle joint and feel for any excessive looseness or instability.
6. Compare the results to the unaffected ankle, if possible.

If there is excessive forward movement of the ankle joint, this may indicate a sprain or tear in the anterior talofibular ligament. However, it is important to note that the prone anterior drawer test should be used in conjunction with other examination techniques and diagnostic tests to accurately diagnose ankle injuries.
