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]
The posterior margin (known as the posterior malleolus) is much more frequently injured than the anterior aspect of the distal tibia. If both the lateral and medial malleoli are broken, this is called a bimalleolar fracture (some of them are called Pott's fractures). If the posterior malleolus is also fractured, this is called a trimalleolar ...
The Haraguchi classification is a system of categorizing posterior malleolus fractures. [1] Classification. Type Description I Posterolateral-oblique type II
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 ...
Ankle fractures may result from excessive stress on the joint such as from rolling an ankle or from blunt trauma. [20] [21] Types of ankle fractures include lateral malleolus, medial malleolus, posterior malleolus, bimalleolar, and trimalleolar fractures. [20] The Ottawa ankle rule can help determine the need for X-rays. [21]
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 ...
Before the introduction of the rules most patients with ankle injuries would have been imaged. However the vast majority of patients with unclear ankle injuries do not have bone fractures. [1] As a result, many unnecessary X-rays were taken, which was costly, time-consuming and a slight health risk due to radiation exposure.
A bimalleolar fracture is a fracture of the ankle that involves the lateral malleolus and the medial malleolus. Studies have shown [ 1 ] that bimalleolar fractures are more common in women, people over 60 years of age, and patients with existing comorbidities.
