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.
A Tillaux fracture is a Salter–Harris type III fracture through the anterolateral aspect of the distal tibial epiphysis. [1] It occurs in older adolescents between the ages of 12 and 15 when the medial epiphysis had closed but before the lateral side has done so, [2] due to an avulsion of the anterior inferior tibiofibular ligament, at the opposite end to a Wagstaffe-Le Fort avulsion fracture
These ligaments include the anterior talofibular ligament (ATFL) and the posterior talofibular ligament (PTFL). [9] The calcaneofibular ligament (CFL), which connects the fibula to the calcaneus, or heel bone, also provides lateral support. The deltoid ligament provides support to the medial part of the ankle (closest to the midline).
The injury to this ligament may vary from simple stretch to complete rupture. Some restraint to further injury is offered by the structures on the inside of the ankle, the medial malleolus and the medial collateral ligament. However, should these structures fail, then the force will be transmitted beyond the anterior inferior tibiofibular ...
Maisonneuve fracture - a spiral fracture of the proximal third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane.; Le Fort fracture of ankle - a vertical fracture of the antero-medial part of the distal fibula with avulsion of the anterior tibiofibular ligament.
Ankle radiographs are used to detect widening of the tibiofibular syndesmosis or medial clear space. The medial clear space is the area between the talus of the ankle and the medial malleolus. Damage to the deltoid ligament and syndesmotic ligaments result in mortise instability, causing the talus to laterally shift and widen the medial clear ...
The anterior ligament of the head of the fibula (anterior superior ligament) consists of two or three broad and flat bands, which pass obliquely upward from the front of the head of the fibula to the front of the lateral condyle of the tibia.
A fractured fibula in addition to detaching the medial malleolus will tear the tibiofibular syndesmosis. [2] The combined fracture of the medial malleolus, lateral malleolus, and the posterior margin of the distal end of the tibia is known as a "trimalleolar fracture". [3] An example of Pott's fracture would be in a sports tackling injury.
