Calcaneofibular ligament

Dr Owen Kang and Dr Henry Knipe et al.

The calcaneofibular ligament (CFL) is the middle ligament of the lateral collateral ligament complex of the ankle and stabilises both the ankle and subtalar joints.

Gross anatomy

The CFL is an extracapsular round cord measuring 20-25 mm long x 6-8 mm width. Its origin is distal to the anterior talofibular ligament on the tip of the lateral malleolus and courses posteroinferiorly and medially to insert onto the lateral surface of the calcaneus.
