In the leg, the syndesmosis between the tibia and fibula strongly unites the bones, allows for little movement, and firmly locks the talus bone in place between the tibia and fibula at the ankle joint. This provides strength and stability to the leg and ankle, which are important during weight bearing.
Many of the arteries, veins, nerves, and muscles in the leg are named according to what bone they are near (e.g. tibialis anterior and the tibial nerve are near the tibia). So the artery that runs near the smaller leg bone had two names: the peroneal artery and the fibular artery. The term fibula eventually became the standard name for the bone ...
The posterior ligament of the lateral malleolus (posterior tibiofibular ligament, posterior inferior ligament) is smaller than the anterior ligament of the lateral malleolus and is disposed in a similar manner on the posterior surface of the syndesmosis.
The bony architecture of the ankle consists of three bones: the tibia, the fibula, and the talus. The articular surface of the tibia may be referred to as the plafond (French for "ceiling"). [10] The medial malleolus is a bony process extending distally off the medial tibia. The distal-most aspect of the fibula is called the lateral malleolus ...
The superior tibiofibular articulation (also called proximal tibiofibular joint) is an arthrodial joint between the lateral condyle of tibia and the head of the fibula.. The contiguous surfaces of the bones present flat, oval facets covered with cartilage and connected together by an articular capsule and by anterior and posterior cruciate ligaments.
Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments: Plantarflexes ankle independent of position of knee; steadies leg on foot
Fracture of the fibula at the level of the syndesmosis. Typical features: at the level of the ankle joint, extending superiorly and laterally up the fibula; tibiofibular syndesmosis intact or only partially torn, but no widening of the distal tibiofibular articulation; medial malleolus may be fractured or deltoid ligament may be torn; variable ...
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.
