was changed:
The lateral collateral ligament (complex) of the ankle is a set of three ligaments that resist inversion of the ankle joint. They are more commonly injured than the medial collateral (deltoid) ligament of the ankle. They run from the lateral malleolus of the fibula to the talus and calcaneus.
Gross anatomy
The fan-like arrangement is composed of three ligaments:
-
anterior talofibular ligament (ATFL)
- anterior component
-
runsextends anteromedially -
arisesfrom the anterior margin of the fibular malleolus to the talus, attached inferior of its lateralmalleolus; inserts onarticular facet and to the lateraltalusaspect of its neck
-
calcaneofibular ligament
- middle component
-
arisesruns fromlateralthe depression anterior to the apex of the fibular malleolus; insertsto a tubercle on the lateralcalcaneuscalcanela surface - crossed by fibularis longus and brevis
-
posterior talofibular ligament (PTFL)
- posterior component
- runs horizontally
-
arisesfrom the distal part of the lateral malleolar fossa; inserts onto the lateral tubercle of the posterior talar process - a tibial slip of fibres connects it to the medial malleolus
-
the syndesmosis can be considered as part of the lateral complex
- anterior inferior tibiofibular ligament (AITFL)
- psoterior inferior tibiofibular ligament (PITFL)
- transverse tibiofibular ligament (TTFL)
- interosseous ligament
