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 4 fičera: 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;
- posterior tibiotalar from the posterior colliculus of the medial malleolus to the posteromedial surface of the talus
Deep fibres[]
The deep fibres (anterior tibiotalar) are attached from the anterior 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 which are supplied by the tibial nerve root value L4 5 S1 2 and 3
