Anterior talocalcaneal ligament

The cervical ligament of the tarsus is a strong, obliquely oriented ligament located within the sinus tarsi of the foot. It extends from the superolateral aspect of the calcaneus to the dorsolateral surface of the neck of the talus.

The cervical ligament lies anterior to the interosseous talocalcaneal ligament and is the primary ligamentous structure in the tarsal sinus, running at approximately a 45-degree angle to the calcaneus.

In terminologia Anatomica 2, the anterior talocalcaneal ligament (Cervical ligament; Toldt) is described as a strengthening band of the anterior part of the Capsula articularis talocalcanea and is to be found in the sinus tarsi immediately at the anterior side of the talocalcaneal joint and some distance behind the Interosseous talocalcaneal ligament. The name “Cervical ligament” does not adequately describe the location of this ligament, which lies lateral to the sinus tarsi, rather than within it, and passes upward and medially from the calcaneus to attach to the lateral surface of the neck of the talus.
