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 Bosworth fracture is a rare fracture of the distal fibula with an associated fixed posterior dislocation of the proximal fibular fragment which becomes trapped behind the posterior tibial tubercle. The injury is caused by severe external rotation of the ankle. [1]
intra-articular fracture of base of Thumb metacarpal: axial load along metacarpal in a partially flexed thumb: Bennett's fracture at Who Named It? Bosworth fracture: David M. Bosworth: fracture of distal fibula with posterior dislocation of the proximal fibula behind the tibia: severe external rotation of the foot "Bosworth fracture dislocation".
The Danis-Weber classification categorizes ankle fractures by the level of the fracture of the distal fibula (type A = below the syndesmotic ligament, type B = at its level, type C = above the ligament), with use in assessing injury to the syndesmosis and the interosseous membrane; Other classification schemes:
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]
The Orthopaedic Trauma Association Committee for Coding and Classification initially published their classification system covering the whole skeleton in 1996. [5] In 2006 [6] they published a revision, unifying the Muller/AO and OTA systems into a single alphanumeric classification, which has been further updated in 2018: [7]
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 .
In the course of avascular necrosis, however, the healing process is usually ineffective and the bone tissues break down faster than the body can repair them. If left untreated, the disease progresses, the bone collapses, [28] and the joint surface breaks down, leading to pain and arthritis. [1]
