Review Of Anterior Drawer Ankle Test References
What is an Anterior Drawer Ankle Test?
The Anterior Drawer Ankle Test is a physical examination used to assess the integrity of the ankle joint ligaments. It is an essential element of the physical examination of the ankle and is commonly used to identify ankle ligament injury, such as a torn anterior talofibular ligament (ATFL). The Anterior Drawer Ankle Test is also known as a talar tilt test, or the lateral drawer test.
How to Perform the Anterior Drawer Ankle Test?
The Anterior Drawer Ankle Test is performed with the patient lying in the supine position with their foot slightly off the edge of the examination table. The examiner then grasps the patient's heel and forefoot, stabilizing the tibia and fibula. The ankle is then passively dorsiflexed and everted, and the examiner applies an anterior force to the talus. The amount of movement of the talus is assessed by the examiner, and the degree of movement is compared to the contralateral ankle.
Interpretation of the Anterior Drawer Ankle Test
The Anterior Drawer Ankle Test is considered to be a positive result if the talus can be moved more than 3mm beyond the expected range of motion for that ankle. If the talus cannot be moved more than 3mm, then it is considered to be a negative result. A positive result indicates a possible injury to the ATFL, while a negative result indicates no injury to the ATFL.
Potential Limitations of the Anterior Drawer Ankle Test
One potential limitation of the Anterior Drawer Ankle Test is that it is subjective in nature, as it relies on the examiner's ability to accurately assess the degree of movement of the talus. Another limitation is that the Anterior Drawer Ankle Test is not specific for an ATFL tear, as other ankle ligament injuries, such as a syndesmotic injury, can also cause an increase in the amount of movement of the talus.
Additional Tests for An anterior Talofibular Ligament Injury
In addition to the Anterior Drawer Ankle Test, other tests can be performed to assess for an ATFL injury. The Squeeze Test and the Talar Tilt Test are two additional tests that can be used to assess for an ATFL injury. In addition, imaging studies such as an X-ray, CT scan, or MRI can be used to confirm the presence of an ATFL injury.
Conclusion
The Anterior Drawer Ankle Test is an essential part of the physical examination of the ankle and is used to assess the integrity of the ankle joint ligaments. The test is considered to be a positive result if the talus can be moved more than 3mm beyond the expected range of motion for that ankle. Although the Anterior Drawer Ankle Test is useful in identifying an ATFL tear, it is not specific for an ATFL tear, and additional tests and imaging studies may be needed to confirm the diagnosis.
