Anatomical terminology

The deltoid ligament (or medial ligament of talocrural joint) is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus. The deltoid ligament is composed of: 1. Anterior tibiotalar ligament 2. Tibiocalcaneal ligament 3. Posterior tibiotalar ligament 4. Tibionavicular ligament. It consists of two sets of fibers, superficial and deep.

Superficial fibres

Of the superficial fibres,

  • tibionavicular pass forward to be inserted into the tuberosity of the navicular bone, and immediately behind this they blend with the medial margin of the plantar calcaneonavicular ligament;
  • tibiocalcaneal descend almost perpendicularly to be inserted into the whole length of the sustentaculum tali of the calcaneus;
  • anterior tibiotalar from the anterior colliculus of the medial malleolus to the anteromedial of the talus

Deep fibres

The deep fibres (posterior tibiotalar) are attached from the posterior colliculus of the medial malleolus to the medial talus and medial tubercle

Coverings

The deltoid ligament is covered by the tendons of the tibialis posterior and flexor digitorum longus.
