Calcaneofibular Ligament (CFL)

The Calcaneofibular Ligament (CFL) is a band of tissue in the ankle that connects the fibula bone (on the outside of the lower leg) to the calcaneus bone (the heel). It helps stabilize the ankle joint and prevents excessive side-to-side movement. Injury to the CFL, often from ankle sprains, can lead to pain, swelling, and instability in the ankle. Understanding the CFL is important in diagnosing and treating ankle injuries, especially for athletes or individuals who are active. Proper care can help restore function and prevent further complications.
