Ligamentum fibulotalare anterius
The anterior talofibular ligament (ATFL) is part of the lateral collateral ligament complex of the ankle. Its role is to stabilize the talus. It is also the weakest of the lateral collateral ankle ligaments.
Gross anatomy
The ATFL is an intracapsular flat two-banded ligament that arises from the distal anterior tip of the lateral malleolus passing anteromedially to the lateral aspect of the talus at the talar neck. It normally measures 6-10 mm long and 2 mm thick.
Variant anatomy
The ATFL is classically described as having two bands, but it may be a single band or three bands. One small cadaveric study put the prevalence of a two-band ATFL at ~50% .
