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 the anterior tibiotalar ligament, tibiocalcaneal ligament, posterior tibiotalar ligament and the 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;
  • posterior tibiotalar pass backward and laterally to be attached to the inner side of the talus, and to the prominent tubercle on its posterior surface, medial to the groove for the tendon of the flexor hallucis longus.

Deep fibres[edit]

The deep fibres (anterior tibiotalar) are attached to the anterior colliculus of the medial malleolus, and below to the anteromedial talus


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