Calcaneofibular ligament

The primary function of the calcaneofibular ligament is to provide lateral stability to the ankle joint. It acts as a restraint during periods of stress, such as when walking, running, or jumping, helping to prevent excessive inversion of the foot. This ligament works in coordination with other ligaments in the ankle, such as the anterior talofibular ligament and posterior talofibular ligament, ensuring proper joint mechanics, enhancing balance, and allowing for controlled movements. By stabilizing the ankle, the calcaneofibular ligament plays a pivotal role in preventing injuries such as ankle sprains, which can occur when the foot rolls excessively outward.

The calcaneofibular ligament is situated on the lateral aspect of the ankle. It originates from the lateral malleolus, a bony prominence at the distal end of the fibula, and descends diagonally toward the calcaneus. This positioning places it between the anterior and posterior talofibular ligaments, making it an essential part of the lateral ligament complex of the ankle. The ligament's location allows it to effectively stabilize the ankle joint while accommodating the movement of the foot during various activities.

• The calcaneofibular ligament is often involved in ankle injuries, particularly in sports where sudden directional changes are common.
• It is one of three primary ligaments that stabilize the lateral side of the ankle, highlighting the importance of ligaments in joint function.
• Strengthening exercises for the muscles around the ankle can help support the calcaneofibular ligament and reduce the risk of injury.
