Medial Ankle Ligament Overview

ligamenta medialis cruris (overview)

The medial ankle ligament complex is the collective term for all ligamentous structures on the medial ankle including the deltoid (superficial and deep layers), tibiocalcaneal, tibionavicular, tibiospring, and tibiotalar components.

Region: Lower Leg
Biomechanics

Function & Actions

The primary medial ankle stabiliser system — resists eversion, external rotation, and lateral talar tilt as a coordinated unit. Individual components provide specific directional constraints that together protect against all medial ankle loading patterns.

Clinical Relevance

Clinical Notes

Comprehensive medial ankle instability requires assessment of all individual deltoid components. MRI and ultrasound can differentiate deep from superficial deltoid tears and identify specific component involvement to guide surgical repair strategy.

Pathology

Common Injuries & Conditions

Medial Ankle Instability Assessment

Systematic evaluation of all medial ankle ligament components by stress testing, ultrasound, and MRI to identify specific deltoid layer and component tears for targeted repair.
