Deltoid ligament

Deltoid Ligament

The Deltoid Ligament is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus.

Anatomy

The deltoid ligament is composed of two layers: superficial and deep. The superficial layer consists of the tibionavicular, tibiocalcaneal, and posterior tibiotalar ligaments. The deep layer is composed of the anterior tibiotalar ligament.

Function

The deltoid ligament primarily serves to resist eversion of the foot, but also secures the foot from forward displacement.

Clinical Significance

Injury to the deltoid ligament is commonly associated with ankle sprains. The severity of the injury can range from a minor sprain to a complete tear.

Treatment

Treatment for a deltoid ligament injury typically involves rest, ice, compression, and elevation (RICE). In severe cases, surgery may be required.
