Calcaneofibular ligament

Calcaneofibular ligament is a ligament located in the foot. It is one of the lateral ligaments of the ankle and plays a crucial role in maintaining the stability of the ankle joint.

Etymology

The term "calcaneofibular" is derived from the Latin words "calcaneus" meaning heel bone and "fibula" meaning clasp. The ligament is named so because it extends from the fibula (a bone in the lower leg) to the calcaneus (the heel bone).

Anatomy

The calcaneofibular ligament is a long, thin, and rounded cord, located behind the lateral malleolus (the outer part of the ankle), and it is covered by the tendons of the Peroneus longus and Peroneus brevis. It stretches from the apex of the lateral malleolus of the fibula downward and backward to a tubercle on the lateral surface of the calcaneus.

Function

The primary function of the calcaneofibular ligament is to stabilize the ankle joint and prevent excessive movement. It restricts excessive inversion and internal rotation of the talus bone in the ankle joint.

Clinical significance

Injury to the calcaneofibular ligament is common in ankle sprains, especially those that occur due to inversion injuries where the sole of the foot turns inwards. Treatment typically involves rest, ice, compression, and elevation (RICE), along with physical therapy to strengthen the ligament and surrounding muscles.
