Talocalcaneal Lateral Ligament Detail

ligamentum talocalcaneum laterale detail

The lateral talocalcaneal ligament runs from the lateral talar process to the lateral calcaneus, providing lateral subtalar joint stability. It runs parallel to and slightly anterior to the calcaneofibular ligament.

Region: Foot & Ankle
Biomechanics

Function & Actions

Resists excessive subtalar inversion, contributes to lateral subtalar joint stability supplementing the CFL, and is disrupted in severe inversion ankle sprains that affect the subtalar joint.

Clinical Relevance

Clinical Notes

Lateral talocalcaneal ligament injury accompanies severe lateral ankle sprains that involve the subtalar joint. Isolated subtalar instability from lateral talocalcaneal ligament insufficiency is a less well-recognised cause of chronic ankle instability than ATFL-CFL complex injuries.

Pathology

Common Injuries & Conditions

Lateral Talocalcaneal Ligament Tear in Subtalar Instability

Ligament disruption producing subtalar joint instability with pain on hindfoot inversion activities, assessed by stress subtalar radiographs and managed by subtalar stabilisation.
