Deltoid ligament of the ankle
Updates to Article Attributes
Body
was changed:
The deltoid ligament or medial collateral ligament of the ankle forms the medial part of the ankle joint. 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 psoteriroposterior borders orof the medial malleolus. The plantar calcaneonavicular ligament can be considered as part of the medial complex.
