The ankle joint is subjected to enormous forces across a relatively small surface area of contact, with up to 1.5 times body weight with gait and greater than 5.5 times bodyweight with more strenuous activity. (medial mortise widening) 2. The Lauge-Hansen classification is the most thorough and complex. The Lauge-Hansen classification is a system of categorizing ankle fractures based on the foot position and the force applied. Danis-Weber classification is a method of describing ankle fractures.

There are 4 categories and 13 subgroups of ankle fractures detailed in the table below. The fractures involve the medial malleolus, the posterior aspect of the tibial plafond (referred to as the posterior malleolus) and the lateral malleolus. Ankle fractures can be classified according to either the AO/OTA, Danis-Weber or Lauge-Hansen classification system. Weber classifications-Classification cannot be used for non-rotational ankle fractures. Tibiofibular syndesmosis intact or only partially torn, but no widening of the distal tibiofibular articulation. This classification categorizes ankle fractures into four types. The influence of a diastasis screw on the outcome of Weber type-C ankle fractures. What is a Weber fracture? The ankle is comprised of the talus bone articulating within - Discussion: - usually involves a supination-adduction injury; - frequently does well w/ closed reduction; - if frx in fibula is transverse, it is type I avulsion fibular frx; - since syndesmotic ligaments are intact, ankle mortise is also stable; - type A: fibula fracture below syndesmosis . The deltoid ligament, which runs from the medial malleolus to the calcaneus, talus, and navicular bones, plays a vital role in maintaining correct talus positioning. This leaflet explains the ongoing management of your injury. Three radiographic views of the ankle (anteroposterior, mortise, and lateral) are necessary to classify an injury with the Lauge-Hansen system.

Weber classification relies solely on the level of the lateral malleolar fracture relative to the ankle joint line.3 The mechanism of injury generally involves a twisting or bending across the joint, whether low-energy as from twist-ing off a curb or high-energy as from a motor vehicle acci-dent. Add posterior tibiofibular ligament rupture, or posterior malleolar fracture. This normally takes approximately 6 weeks to unite (heal) although pain . 2. The major symptoms are pain in the affected area and decreased range of motion. Weber c stage 3 also known as a maisonneuve fracture.

A talar shift of 1 mm results in a 42 percent . Weber classified them as: type A - infrasyndesmotic type B - transsyndesmotic type C - suprasyndesmotic These fractures are identical to the fractures described by Lauge-Hansen as supination-adduction, supination-exorotation and pronation-exorotation. The Lauge-Hansen classification is based on a rotational mechanism of injury. Topics with the highest number of questions. The most commonly used Lauge-Hansen classification The first is typically a very high break or fracture in the fibula the smaller of the two bones between your ankle and your knee. The Lauge-Hansen classification is a system of categorizing ankle fractures based on the foot position and the force applied. "Bearing weight" counts even if the patient .

Classification (Danis-Weber System) System based on level of the fibular fracture and characterizes stability of fracture Tibial plafond and the two malleoli is referred to as the ankle "mortise" (or talar mortise) Type A Fibula fracture below ankle joint/distal to plafond Medial malleolus often fractured Tibiofibular syndesmosis intact Weber Classification (Ankle fractures) Pronounced "webber" The system is based off where the fracture line on the fibula hits the tibio-talar joint. Diagnosis is made with plain radiographs of the ankle. The Danis-Weber classification[1](Weber classification) is a simple method for classifying fractures of lateral ankle fracturesand is based on radiographic criteria.

Those fractures below the plafond are Weber A, at the plafond Weber B, and above the plafond Weber C. Weber C fractures generally have a higher risk of syndesmotic injury. Treatment can be nonoperative or operative depending on fracture displacement, ankle stability, presence of syndesmotic injury, and patient activity demands. Wear this until swelling decreases. accounts for 35-40% of overall tibial growth and 15-20% of overall lower extremity growth rate of growth is 3-4 mm/year growth continues until 14 years in girls and 16 years in boys closure occurs during an 18 month transitional period pattern of closure occurs in a predictable pattern: central > anteromedial > posteromedial > lateral Of them, 32.0% treat more than 30 ankle fractures a year.

Philadelphia: Wolters Kluwer/Lippincott Williams & Wilkins Health, 2010. The Weber ankle fracture classification (or Danis-Weber classification) is a simple system for classification of lateral malleolar fractures, relating to the level of the fracture in relation to the ankle joint, specifically the distal tibiofibular syndesmosis. Classification Grade Sequence Supination-Adduction: Talofibular . A broken ankle, also called an ankle fracture, is a common childhood injury. Medial malleolus may be fractured or deltoid ligament may be torn. Ankle Sprain Protocol Immediately begin using: Elevate the ankle above heart level until swelling subsides. Maintaining congruency of the ankle joint is therefore critical to the long-term viability of the ankle [9]. Classification Grade Sequence Supination-Adduction: Talofibular . fixation usually not required when fibula fracture within 4.5 cm of plafond. A Weber C may be any height above the syndesmosis, including in the proximal fibula. Ankle fractures are very common injuries to the ankle which generally occur due to a twisting mechanism. Along with the Weber classification , these systems are useful tools for describing and classifying ankle injuries. Most isolated midfoot fractures affect the navicular or more rarely the cuboid bones. Conclusion The Danis-Weber classification presented the highest reproducibility among instruments and the evaluator's little experience had no negative influence on the reproducibility of ankle .
