Malleolus

The Malleolus is a specific structure in the human anatomy that is found in the lower leg. There are two malleoli in each leg, known as the medial and lateral malleoli. These structures are part of the tibia and fibula bones respectively, and they play a crucial role in the stability and movement of the ankle joint.

Medial Malleolus

The Medial Malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia. It is located on the inside of the ankle and is typically the most prominent of the two malleoli. The medial malleolus is important for the attachment of several ligaments, including the deltoid ligament, which provides medial stability to the ankle joint.

Lateral Malleolus

The Lateral Malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. It is located on the outside of the ankle. The lateral malleolus is important for the attachment of several ligaments, including the anterior talofibular ligament and the calcaneofibular ligament, which provide lateral stability to the ankle joint.

Clinical Significance

Injuries to the malleoli, such as fractures, are common and can result from a variety of causes, including falls, sports injuries, and trauma. Treatment for malleolar fractures depends on the severity of the injury and can range from conservative management with immobilization to surgical intervention.
