Purpose[edit | edit source]
The purpose of this test was to determine whether ankle mechanical instability or hypermobility in the sagittal plane of the talocrural joint (or upper ankle joint) is present.
Technique[edit | edit source]
The patient is supine, the ankle joint is in 20° of flexion, the heel is resting on the palm of the examiner's hand that is resting on the table. thereby stabilizing the calcaneus. The examiner then stabilises the tibia and fibula whilst drawing the calcaneus anteriorly observing the amount of anterior translation at the lateral aspect of the ankle and the change in end feel. The amount of anterior translation and the eventual weakening of the end feel, changing from hard ligamentous to weak elastic, is observed. An anterior translation greater than 1 cm compared to the healthy contralateral ankle and an evident weakening of the end feel are most indicative of a partial rupture or complete rupture of the anterior talofibular ligament. The test is graded on a 4-point scale. 0 represents no laxity and 3 represents gross laxity.
Evidence[edit | edit source]
Anterior drawer has sensitivity of 86 percent and specificity of 74 percent for a diagnostic test of 160 patients with an inversion ankle sprain when compared to an arthrogram.[2] In a prospective, blinded, diagnostic-accuracy study, Croy et al. measured diagnostic accuracy of the anterior drawer test of the ankle in sixty-six subjects with a history of lateral ankle sprain. Using ultrasound imaging during performance of the anterior drawer test the talofibular interval was measured digitally.[3]
Sensitivity of the the anterior drawer test was 0.74 (95% confidence interval [CI]: 0.58, 0.86) and 0.83 (95% CI: 0.64, 0.93) at the 2.3 mm or greater and 3.7 mm or greater reference standards, respectively. Specificity of the test was 0.38 (95% CI: 0.24, 0.56) and 0.40 (95% CI: 0.27, 0.56), respectively. Positive likelihood ratios were 1.2 and 1.4, whereas the negative likelihood ratios were 0.66 and 0.41, respectively.[3] The recent cross-sectional diagnostic study found out anterior drawer test to be a valuable method of identifying mechanical ankle instabilities[4].
