Ligaments of Ankle Joint – 9 Previous Year AIIMS PG Question for Practice


  • The ankle joint is bound by the strong Deltoid ligament and three lateral ligaments:
  • Anterior talofibular ligament( most commonly affected on ankle joint injury)
  • Posterior talofibular ligament
  • Calcaneofibular ligament 
  • The major ligaments of the ankle are:
  1. Anterior tibiofibular ligament, which connects the tibia to the fibula;
  2. Lateral collateral ligaments, which attach the fibula to talus and calcaneus and gives the ankle lateral stability; and,
  3. Deltoid ligaments, which connect the tibia to the talus and calcaneus and provide medial stability.
Deltoid ligament
  • Supports the medial side of joint
  • Proximally , it is attached to the medial malleolus
  • Distally, it is attached to four places
  • Sustentaculum tali of calcaneus
  • Calcaneonavicular ligament(support head of talus)
  • Navicular tuberosity
  • Medial surface of talus
  • Deltoid ligament is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of medial malleolus.
  • Deltoid ligament is composed of 
  1. Anterior Tibiotalar Ligament,
  2. Tibiocalcaneal Ligament,
  3. Posterior Tibiotalar Ligament, and
  4. Tibionavicular Ligament.
  • It consists of two sets of fibers, superficial and deep
  • Its middle portion, together with the calcaneofibular ligament, binds the bones of the leg firmly to the foot, and resists displacement in every direction.
  • Its anterior and posterior fibers limit extension and flexion of the foot respectively, and the anterior fibers also limit abduction
  • Calcaneofibular ligament is attached at the lateral malleolus and to the lateral surface of calcaneum.
  • Ligamentous support is more important during plantar flexion
  • Ankle  joint is more stable at dorsi-flexed position
  • Deltoid ligament , Lateral ligament, Shape of the superior talar articular surface stablizes ankle joint
  • Deltoid ligament is very strong
  • It usually resists a force which fractures the malleolus, to which it is attached. 
Tibiofibular ligament
  • Anterior and posterior talofibular ligaments support the lateral side of the joint from lateral malleolus to the posterior and anterior ends of talus.
  • Though it does not span across the ankle joint itself, the syndesmotic ligament makes an important contribution to the stability of ankle.
  • This ligament spans the syndesmosis (the articulation between the medial aspect of  distal fibula and the lateral aspect of the distal tibia.
  • An isolated injury to this ligament is often called high ankle sprain.
