Medial ligament of talocrural joint
|Medial ligament of talocrural joint|
Ligaments of the medial aspect of the foot.
|Latin||Ligamentum collaterale mediale articulationis talocruralis, ligamentum deltoideum|
|From||Talus bone (tarsal bones)|
|To||Medial malleolus of the tibia|
The medial ligament of talocrural joint (or deltoid ligament) 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 fibres, superficial and deep.
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.
The deep fibres (anterior tibiotalar) are attached to the anterior colliculus of the medial malleolus, and below to the anteromedial talus
