The Maisonneuve fracture generally follows a specific pattern of injury. The following are described as subsequent events that result in a Maisonneuve fracture: [3] [4] [12] Forceful, external rotation of the ankle joint results in the tearing of the deep deltoid ligament and/or an avulsion fracture of the medial malleolus.
Medial malleolus transverse fracture or disruption of deltoid ligament; Anterior tibiofibular ligament disruption; Lateral short oblique or spiral fracture of fibula (anterosuperior to posteroinferior) above the level of the joint; Posterior tibiofibular ligament rupture or avulsion of posterior malleolus
Ankle fractures may result from excessive stress on the joint such as from rolling an ankle or from blunt trauma. [1] [2] Types of ankle fractures include lateral malleolus, medial malleolus, posterior malleolus, bimalleolar, and trimalleolar fractures. [1] The Ottawa ankle rule can help determine the need for X-rays. [2]
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 ...
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.
Le Fort's fracture of the ankle is a vertical fracture of the antero-medial part of the distal fibula with avulsion of the anterior tibiofibular ligament, [1] opposite to a Tillaux-Chaput avulsion fracture. The injury was described by Léon Clément Le Fort in 1886. [2]
medial malleolus occasionally fractured; usually stable: occasionally nonetheless requires an open reduction and internal fixation (ORIF) particularly if medial malleolus fractured; Type B. 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
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]
