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[edit]

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[edit]

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

Coverings[edit]

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