1. Anterior talofibular ligament - ATFL:
Anterior aspect of lateral malleolus to talar neck
Just anterior to fibular articular surface.
Best seen on axial MR - thin band between lateral malleolus and talar body
May be bifasciculated or striated
2. Posterior talofibular ligament - PTFL:
Broad, fan-shaped origin from fibular fossa of distal fibula to posterior aspect of distal tibia
Strongest
Seen on axial and coronal images
Appears striated (interspersed fat)
May show heterogeneity and thickening
3. Calcaneofibular ligament - CFL:
Between tip of lateral malleolus to small tubercle on lateral aspect of the calcaneus
Seen on coronal and axial
Deep to peroneal tendons
May be seen incompletely
