Translations
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 Tibionavicular Ligament. It consists of two sets of fibres, superficial and deep.
Of the superficial fibres,
The deep fibres (anterior tibiotalar part) are attached, above, to the tip of the medial malleolus, and, below, to the medial surface of the talus.
The deltoid ligament is covered by the tendons of the Tibialis posterior and Flexor digitorum longus.
The anterior and posterior talofibular and the calcaneofibular ligaments were formerly described as the three fasciculi of the external lateral ligament of the ankle-joint.
