The calcaneofibular ligament of the musculoskeletal system is characterized by being least functional ligament of the lateral ligament complex.
It is part of the ankle joint. It consists of fibrous dense regular connective tissue of collagen fibers.
Its unique structural feature is that it is a round cord that connects the lateral malleolus to the calcaneous.
The calcaneofibular ligament as well as all other bones, muscles, and ligaments of the body are derived of mesodermal origin in the embryo.
The function of the calcaneofibular ligament is to support the lateral ankle, however it may not play a significant role in ankle stability.
Common diseases include ligament tears/sprains and fractures.
Commonly used diagnostic procedures include clinical history, physical exam, and MRI.
It is usually treated with physical therapy and NSAIDs for sprains. Fractures and dislocations are often treated with surgery.
