Deltoid ligament
Deltoid Ligament
The Deltoid Ligament (pronounced: DEL-toid LIG-uh-ment), also known as the medial ligament of the talocrural joint, is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus.
Etymology
The term "Deltoid" is derived from the Greek letter Delta, due to the ligament's triangular shape. The term "Ligament" comes from the Latin "ligamentum", meaning "a band".
Anatomy
The Deltoid Ligament is composed of two layers: a superficial layer and a deep layer. The superficial layer consists of the tibionavicular, tibiocalcaneal, and posterior tibiotalar ligaments. The deep layer is composed of the anterior tibiotalar ligament.
Function
The primary function of the Deltoid Ligament is to prevent excessive eversion and external rotation of the foot. It also provides stability to the Ankle joint during weight-bearing activities.
