Anterior Talocalcaneal Ligament

Anterior talocalcaneal ligament (highlighted in red) in relation to other foot ligaments.

The Anterior Talocalcaneal Ligament (ATCL) is a ligament in the human foot, specifically located within the subtalar joint. It is one of the several ligaments that contribute to the stability of the foot and ankle.

Anatomy

The Anterior Talocalcaneal Ligament originates from the neck of the talus bone and inserts into the anterior process of the calcaneus. It is a short, strong band that is oriented obliquely downward and laterally.

Function

The primary function of the Anterior Talocalcaneal Ligament is to provide stability to the subtalar joint, preventing excessive movement and potential injury. It also plays a role in the complex movements of the foot, including inversion and eversion.

Clinical Significance

Damage to the Anterior Talocalcaneal Ligament can result in instability of the subtalar joint, leading to conditions such as subtalar instability or ankle sprain. Treatment typically involves rest, physical therapy, and in severe cases, surgery.
