What are the ATF and CF ligaments?
The ATF ligament keeps the ankle from sliding forward and the CF ligament keeps the ankle from rolling over on its side. SymptomsInitially the ankle is swollen, painful, and may turn echymotic (bruised).
What bones does the ATF ligament attach?
Ankle Anatomy: Muscles and Ligaments
- The anterior talofibular ligament (ATFL), which connects the front of the talus bone to a long bone in the lower leg called the fibula.
- The calcaneofibular ligament (CFL), which connects the calcaneus, or heel bone, to the fibula.
What does the anterior tibiofibular ligament do?
The key function of the anterior tibiofibular ligament is to stabilize the ankle syndesmosis by holding the bones together at the joint.
What is the role of the anterior and posterior tibiofibular ligaments?
The anterior and posterior inferior tibiofibular ligaments, the interosseous ligament, and the interosseous membrane act to statically stabilize the joint. During dorsiflexion, the wider portion anteriorly more completely fills the mortise, and contact between the articular surfaces is maximal.
What is the ATF in the ankle?
ATF stands for anterior talofibular. The anterior or front talofibular ligament is located in the ankle joint and is commonly sprained or injured.
What is the main ligament in your ankle?
The major ligaments of the ankle are: the anterior tibiofibular ligament (2), which connects the tibia to the fibula; the lateral collateral ligaments (3), which attach the fibula to the calcaneus and gives the ankle lateral stability; and, on the medial side of the ankle, the deltoid ligaments (4), which connect the …
What movement does the anterior tibiofibular ligament prevent?
The purpose of these ligaments is to hold the tibia and the fibula together when the joint is loaded [3]. Those ligaments have different functions in the tibiofibular joint. The anterior tibiofibular ligament prevents extreme uncontrolled movement of the fibula and also external rotation of the talus.
What is the function of the posterior Talofibular ligament?
Background. The lateral ankle ligament complex consisting of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL) and the posterior talofibular ligament (PTFL) is known to provide stability against ankle joint inversion.
Which motion causes an ATF ankle sprain?
An inversion ankle sprain is the most common type of ankle sprain and occurs when the foot is turned inward beyond ligamentous and muscular control. This often occurs in activities involving lateral movements, jumping, and running.
Which ligament is involved in a high ankle sprain?
The connection of the two ankle bones (tibia and fibula) are formed by four ligaments called the syndesmosis. This is the ligament that is frequently injured in high ankle sprains. CAUSES: Injuries of the syndesmosis are commonly associated with ankle fractures.
