Deltoid ligament of the ankle

Last revised by Assoc Prof Craig Hacking on 17 Dec 2020

The complex of the medial collateral ligaments 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 ligament complex.
