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 supports the ankle joint and also resists excessive eversion of the foot. [1] The deltoid ligament is composed of 4 fibers:

Damage to the deltoid ligament and syndesmotic ligaments result in mortise instability, causing the talus to laterally shift and widen the medial clear space. [ 4 ] [ 12 ] A clinical study, conducted in 2006 and published in the Journal of Bone and Joint Surgery , found that the medial clear space size of a normal ankle and an injured ankle ...
These ligaments include the anterior talofibular ligament (ATFL) and the posterior talofibular ligament (PTFL). [9] The calcaneofibular ligament (CFL), which connects the fibula to the calcaneus, or heel bone, also provides lateral support. The deltoid ligament provides support to the medial part of the ankle (closest to the midline).
The ankle joint is bound by the strong deltoid ligament and three lateral ligaments: the anterior talofibular ligament, the posterior talofibular ligament, and the calcaneofibular ligament. The deltoid ligament supports the medial side of the joint, and is attached at the medial malleolus of the tibia and connect in four places to the talar ...
The middle (middle) deltoid: Responsible for shoulder abduction (lifting the arm away from the body). The posterior (back) deltoid: Assists with shoulder extension and outward rotation.
The summit of the medial malleolus is marked by a rough depression behind, for the attachment of the deltoid ligament. The major structure that passes anterior to the medial malleolus is the saphenous vein. Structures that pass behind medial malleolus deep to the flexor retinaculum: Tibialis posterior tendon; Flexor digitorum longus
The medial surface presents at its upper part a pear-shaped articular facet for the medial malleolus, continuous above with the trochlea; below the articular surface is a rough depression for the attachment of the deep portion of the deltoid ligament of the ankle-joint.
