Deltoid ligament of the ankle
Updates to Article Attributes
Body
was changed:
The deltoid ligament orligament of the ankleligaments forms the medial part of the ankle joint is collectively called deltoid ligament. It attaches the medial malleolus to multiple tarsal bones.
Gross anatomy
The ligament is composed of two layers. The superficial layer has variable attachments and crosses two joints while the deep layer has talar attachments and crosses one joint:
It is a strong triangular band attached to the apex and the anterior and posterior borders of the medial malleolus. The plantar calcaneonavicular ligament can be considered as part of the medial complex.
-
superficial layer (from anterior to posterior)
-
tibionavicular ligament (anterior)
- pass forwards to the navicular tuberosity behind which they blend with the medial margin of the plantar calcaneonavicular ligament
-
tibiocalcaneal ligament (intermediate)
- descend almost vertically to the entire length of the sustentaculum tali
-
posterior tibiotalar ligament (posterior)
- pass posterolateral to the medial side of the talus and its medial tubercle
-
tibionavicular ligament (anterior)
-
deep layer: this layer is intra-articular and is covered by synovium
-
anterior tibiotalar ligament (ATTL)
- short and thin ligament, pass from the tip of the medial malleolus to the non articular part of the medial talar surface
- crossed by the tendons of the tibialis posterior and flexor digitorum longus
-
anterior tibiotalar ligament (ATTL)
