Lauge-Hansen’s classification, which was published in a issue of Archives of Surgery, has become one of the most widely used ankle. The Lauge-Hansen classification is a system of categorizing ankle fractures based on the foot position and the force applied. Classification, Description, Notes. Supination External Rotation, Most common mechanism (% of all fractures). 1, Anterior tibiofibular ligament rupture.

Open reduction and internal fixation with restricted weight bearing for 6 weeks. Appropriate reconstruction therefore is clwssification, and a classification scheme that identifies injury patterns and guides treatment would be desirable.
Weber C This is a fracture above the level of the syndesmosis. He subsequently undergoes surgical fixation, and a post-operative radiograph is shown in Figure A. Classification The fracture starts at the level of the ankle joint and extends proximally, i. In many cases it is visible on the radiographs of the ankle, but in some cases the fracture is located high and will only be visible on a radiograph of the lower leg.
Open reduction and internal fixation with restricted weight bearing for 2 weeks. Stage 2 Stage 2 is uncommon and easy to detect. Notice the horizontal orientation of the fracture lines. This classification system took into consideration the position of the distal fibular fracture in relation to the syndesmosis [ 427 ].
Contrary to the findings of Hermans et al. One of the keys to the Lauge-Hansen classification is the geometry of the medial malleolus fracture. Niel Lauge-Hansen used freshly amputated limbs to develop an ankle fracture classification based on foot position at the time of the traumatic event supination or pronation and the direction of the deforming forces abduction, adduction, or external rotation [ 12 ]. In stage 2 the talus exorotates further and since the foot is in supination, the lateral malleolus is held tightly in place by the lateral collateral ligaments.
Notice that on the radiograph of the ankle no fracture is seen. First notice the oblique fibular fracture, which is best seen on the lateral view.
Ankle fracture – Weber and Lauge-Hansen Classification
Every ligamentous rupture has it’s avulsion fracture counterpart. This is in contrast to the Danis-Weber classification that completely ignores the medial and posterior structures.
A posterior malleolus fracture as an classiification finding is very uncommon. Supination- weight on lateral foot. Stage 2 is uncommon and easy to detect. Inter-observer reliability and intra-observer reproducibility of the Weber classification of ankle fractures. Which of the following is the best method to assess the integrity of the syndesmosis?
In daily practice most use the Weber system, which is clasification to memorize, while the Lauge-Hansen seems rather difficult at first glance. The oblique course of the fracture is typical for Weber B and results from the exorotation of the talus that pushes against the fixed lateral malleolus.
An AP and lateral radiograph are shown in figures A and B respectively. This is stage 3. Here another typical Weber B fracture stage 4. According to Lauge-Hansen, it is the result of an exorotation force on the pronated foot. This is stage 2 and we have to assume, that the anterior syndesmosis is ruptured. Please vote below and help us build the most advanced adaptive learning platform in medicine The complexity of this topic is appropriate for?
Scroll through the images. This can best be demonstrated by giving an example. Epidemiology of adult fractures: Radiographs from the ER are provided in figures Laugge and B. The radiographs shows a Weber C fracture.
Observer variation in the Lauge-Hansen classification of ankle fractures: What is an advantage of using lateral neutralization plating instead of posterior antiglide plating? Classification The fracture classifcation classified according to Weber as a type B fracture.
Additional radiographs of the lower extremity were ordered and they demonstrate a high fibular fracture, i. Observer variation in the radiographic classification of ankle fractures.
L8 – 10 years in practice. In Stage 3, transverse or comminuted fibula fractures were observed above the level of the tibial plafond [ 12 ]. For interobserver agreement, the mean kappa value was 0. Are low-energy open ankle fractures in the elderly the new geriatric hip fracture?

Lauge-Hansen classification – Wikipedia
Weber classified them as: In what direction is the fibula most unstable? They showed that the proposed soft tissue injuries associated with the different Lauge-Hansen categories and stages were not accurately predicted [ 5 ]. It is the most difficult fracture to diagnose and the Lauge-Hansen system will help classjfication to understand the fracture-mechanism, as this will be an enormous help.
