In contrast, the more prominent anterior tubercle prevents any anterior translation of the lateral malleolus. The ATFL is a short ligament that widens slightly from top to bottom. This is down to the shallower posterior tibial tubercle permitting a degree of posterior escape. The anterior ligament of the lateral malleolus (anterior tibiofibular ligament or anterior inferior ligament) is a flat, trapezoidal band of fibers, broader below than above, which extends obliquely downward and lateralward between the adjacent margins of the tibia and fibula, on the front aspect of the syndesmosis.. The fibula pivots on the posterior inferior tibiofibular ligament, with more rotational movement anteriorly . Muscular Attachments The ligament consists of two to three fascicles that arise from the anterior aspect of … attachment sites of the anterior talofibular ligament should not raise suspicion of a fracture. Anatomy. Lateral Malleolus Neck of Talus Restrain anterior displacement of the talus in respect to the fibula and tibia. weakest of the lateral ligaments. There is also a variant of this ligament known as Bassett’s ligament that is inserted at the extreme distal aspect of the fibula and is likely to irritate the dome of the talus. The anterior tibiofibular ligament located deep within the leg, near the ankle.This ligament holds the two bones of the lower leg – the tibia and fibula – … Anterior Tibiofibular Ligament - It is weaker than its posterior counterpart; however, it takes a similar course on the anterior surface of the joint. Anterior Talofibular Ligament (ATFL) Function. Function [edit | edit source] The superior tibiofibular joint is reinforced by the anterior and posterior tibiofibular ligaments. Weaker than the PITFL. -Proximal attachment: arising just posterior to the tibionavicular ligament, anterior tibiotalar ligament occupies an intermediate position on the anterior portion of the medial malleolus, anterior to the apex-Distal attachment: the non-articular part of the medial surface of the talus Most commonly damaged ligament of the ankle. LIGAMENT DESCRIPTION PROXIMAL ATTACHMENT DISTAL ATTACHMENT ROLE Anterior Talofibular Ligament (ATFL) Flat Weak Band that extends Anteriomedially. PROXIMAL ATTACHMENT DISTAL ATTACHMENT ROLE / FUNCTION; Anterior-inferior tibiofibular ligament (AITFL) Trapezoid shape (the tibial insertion is wider) The ligament runs obliquely. 20% intra-articular Anterior tubercle of the distal tibia Anterior surface of the distal fibula at the lateral malleolus Anterior talofibular – The anterior ligament of the lateral malleolus (anterior tibiofibular ligament or anterior inferior ligament) is a flat, trapezoidal band of fibers, broader below than above, which extends obliquely downward and lateralward between the adjacent margins of the tibia and fibula, on the front aspect of the syndesmosis. extends from the anteroinferior border of the fibula to the neck of the talus. primary restraint to inversion in plantar flexion. resists anterolateral translation of talus in the mortise. ankle fracture. Resists Inversion in planterflexion. It traverses the anterior aspect of the joint. Attachments [edit | edit source] The anterior talofibular ligament originates from the anterior edge of the lateral malleolus of the fibula and attaches to the neck of the talus, in front of the lateral malleolar facet. The bifurcate ligament, sinus tarsus, the anterior inferior tibiofibular, calcaneofibular, and anterior talofibular ligament. The anterior and posterior inferior tibiofibular ligaments, the interosseous ligament, and the interosseous membrane act to statically stabilize the distal tibiofibular joint. A taut interosseous membrane results when the flexors of the foot contract during stance phase. The anterior ligament of fibular head is short, wide and thick.
