On X-rays, there can be a fracture of the medial malleolus, the lateral malleolus, and/or of the anterior/posterior margin of the distal tibia. The posterior margin (known as the posterior malleolus ) is much more frequently injured than the anterior aspect of the distal tibia.
The Maisonneuve fracture is a spiral fracture of the proximal third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane. There is an associated fracture of the medial malleolus or rupture of the deep deltoid ligament of the ankle. This type of injury can be difficult to detect. [1] [2]
The Herscovici classification is a system of categorizing medial malleolus fractures of the distal tibia based on level. Classification. Type Description A
Studies have shown [3] that bimalleolar fractures are more common in women, people over 60 years of age, and patients with existing comorbidities. [3] A trimalleolar fracture is a fracture of the ankle that involves the lateral malleolus, the medial malleolus, and the distal posterior aspect of the tibia, which can be termed the posterior ...
In 78% of cases, a fracture of the fibula is associated with a tibial fracture. [6] Since the fibula is smaller and weaker than the tibia, a force strong enough to fracture the tibia often fractures the fibula as well. Types include: Trimalleolar fracture - involving the lateral malleolus, medial malleolus and the distal posterior aspect of the ...
medial malleolus may be fractured or deltoid ligament may be torn; variable stability; Type C. Fracture of the fibula proximal to the syndesmosis. Typical features: above the level of the ankle joint; tibiofibular syndesmosis disrupted with widening of the distal tibiofibular articulation; medial malleolus fracture or deltoid ligament injury ...
A trimalleolar fracture is a fracture of the ankle that involves the lateral malleolus, the medial malleolus, and the distal posterior aspect of the tibia, which can be termed the posterior malleolus. The trauma is sometimes accompanied by ligament damage and dislocation. [1]
Talofibular ligament sprain or distal fibular avulsion fracture; Vertical medial malleolus fracture and impaction of anteromedial distal tibia; Supination-External rotation: Anterior tibiofibular ligament sprain; Lateral short oblique fibular fracture (anteroinferior to posterosuperior) Posterior tibiofibular ligament rupture or avulsion of ...
