Purpose
[edit | edit source]
The purpose of this test was to determine whether ankle mechanical instability or hypermobility in the sagital plane of the talo-crural joint (or upper ankle joint) is present.
Technique
[edit | edit source]
The patient is supine, the knee joint is in 20° of flexion, the heel is
resting on the palm of the examiners hand that is resting on the table hereby
stabilizing the calcaneus. The examiner pushes the tibia (and fibula)
posteriorly observing the amount of posterior translation of the tibia and
fibula at the lateral aspect of the ankle and the change in endfeel. The amount
of posterior translation and the eventual weakening of the endfeel,
changing from hard ligamentous to weak elastic, is observed. A posterior translation superior tot 1 cm compared to the healthy contralateral ankle and an evident weakening of the endfeel 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.<o:p></o:p>
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. The +LR .22 and -LR .0018.
