According to Lauge-Hansen the fracture results from an adduction force on the supinated classifocation. Views Read Edit View history.
Therefore, it is not yet well understood how much clinical guidance the Lauge-Hansen system offers. The Lauge-Hansen classification will give you the fracture mechanism and the preliminary stage of the ankle injury.
This can best be demonstrated by giving an example. This is called a pull off type of fracture in contrast to a push off type, which is seen as an oblique or vertical fracture. Medial malleolus Anterior syndesmosis Fibula Posterior syndesmosis.

In another investigation by Haraguchi and Armiger classivication 6 hwnsen, the mechanism by which the distal fibula breaks in supination external rotation injuries was questioned, as the authors were able to produce a short oblique fracture of the distal fibula with the foot in the pronated position.
Final report Weber C fracture stage 4. At the eight-week postoperative visit, you are asked to fill out a return to work form.

According to Lauge Hansen the oblique fibular fracture indicates Supination Exorotation injury stage 2 or higher.
Retrieved 27 October Weber C This is a fracture above the level of the syndesmosis. J Bone Joint Surg Am. Add cclassification tibiofibular ligament rupture or posterior malleolar fracture. Immediately after the injury lajge injured parts may again align, which can make it difficult to detect the injuries. Past medical history includes insulin dependent diabetes mellitus for 35 years.
Weber B starts anterolaterally and the sequence is: There is a widened medial clear space, which indicates a rupture of the medial collateral band, i. First impression The radiographs show a fracture of the posterior malleolus. At first impression there is a Weber B fracture stage 2.
