The Danis–Weber classification (often known just as the Weber classification) is a method of describing ankle fractures. It has three categories: [1] Type A. Fracture of the fibula distal to the syndesmosis (the connection between the distal ends of the tibia and fibula). Typical features: below level of the ankle joint; tibiofibular ...
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]
Transverse comminuted fracture of the fibula above the level of the syndesmosis; Pronation-External rotation: 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
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:
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
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".
A tib-fib fracture is a fracture of both the tibia and fibula of the same leg in the same incident. 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:
Evidence supports the rules as an accurate instrument for excluding fractures of the ankle and mid-foot, reducing the number of unnecessary investigations and length of stay in emergency departments. [3] The original study reported that the test was 100% sensitive and reduced the number of ankle X-rays by 36%. [4]
