Purpose

To examine the ankle for injury of the Anterior Talofibular ligament and the Calcaneofibular ligament.

Technique

Patient is seated with foot and ankle unsupported. The foot is positioned in 10-20 degrees of plantarflexion. The distal lower leg is stabilized with one hand just proximal to the malleloi and the hindfoot is inverted with the other hand. The lateral aspect of the talus is palpated to determine if tilting occurs. The laxity is compared to the contralateral side. ^{[1]  [2]}

Evidence

In a prospective study of 244 patients with ankle lesions, a comparison between the talar tilt and the anterior drawer sign was made, leading to the following conclusions; ^[3]

• Ligament lesions that are not identified by the talar tilt examination may be diagnosed by the anterior drawer sign
• The anterior drawer sign cannot replace the talar tilt examination, or vice versa. The two methods are complementary.
• It is not possible to differentiate between an isolated lesion of the anterior talofibular ligament and a combined lesion of the anterior talofibular and the calcaneofibular ligaments by the two methods.

The reliability of the radiographic talar tilt test was evaluated using MRI in 112 athletes with injuries to the lateral ligaments of the ankle. Twenty-five athletes with a talar tilt of 15″ were treated operatively. lntraoperative findings and the talar tilt test were compared with MR imaging results. The results suggested that MRI is a reliable method for diagnosing injuries of the lateral ankle ligaments. The talar tilt test cannot evaluate the specific pathology of lateral ankle ligaments, but it was reliable in indicating complete double-ligament ruptures (anterior talofibular and calcaneo-fibular ligaments), when talar tilt was 15″ or more than on the uninjured side.

Sensitivity 67, Specificity 75, LR+ 2.7, LR- 0.44.^[4]
