Ankle ligaments & syndesmosis

The ankle from the lateral side: distal tibia and fibula, talus and calcaneus with the anterior and posterior talofibular ligaments, the calcaneofibular ligament and the anterior inferior tibiofibular ligament of the syndesmosis.

What to look at

1The lateral ligament complex has three parts: the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL) and the posterior talofibular ligament (PTFL).
2The ATFL is the weakest and is injured first in an inversion sprain of the plantarflexed ankle; the CFL is torn next.
3Above the joint, the anterior inferior tibiofibular ligament is part of the syndesmosis, with the posterior inferior tibiofibular, transverse and interosseous ligaments.
4A Weber C fibular fracture lies above the syndesmosis and usually disrupts it.

Hotspots

1Tibia — The medial malleolus and the deltoid ligament lie on the far side.
2Fibula — The lateral malleolus extends further distally than the medial.
3Anterior inferior tibiofibular ligament — Part of the syndesmosis; injured in a high ankle sprain.
4Anterior talofibular ligament — Fibula to talar neck; the weakest lateral ligament and the first to tear.
5Calcaneofibular ligament — Fibular tip to calcaneus, deep to the peroneal tendons; spans the ankle and subtalar joints.
6Posterior talofibular ligament — The strongest of the three; rarely torn in isolation.
7Calcaneus — The CFL inserts on its lateral surface.
