Associated with risk of avascular necrosis (AVN) Hawkins Type I: Nondisplaced talar neck fracture. Three radiographic views of the ankle (anteroposterior, mortise, and lateral) are necessary to classify an injury with the Lauge-Hansen system. - Radiographic Studies. Ankle fractures involving the fibula proximal to the distal tibiofibular syndesmosis. Type A: fracture below the ankle joint; Type B: fracture at the level of the joint, with the tibiofibular ligaments usually intact. in the ao/ota classification, ankle fractures are classified as infrasyndesmotic (correlating to danis-weber type a injuries), transsyndesmotic (correlating to danis-weber type b injuries) or suprasyndesmotic (correlating to danis-weber type c injuries) with further subsets based on presence or absence of medial or posterior malleolar injuries [ Weber Classification Fibula fractures are classified into three groups depending on where the fracture occurs. Illustration of typical locations of Weber A, B and C fractures. 1. Pages 476-506 Those fractures below the plafond are Weber A, at the plafond Weber B, and above the plafond Weber C.

Pronation External Rotation Pronation Abduction. cut with 1.5-2cm exposed out of olecranon. According to our new 3-D CT classification of medial malleolus, there were 12.1% of type 1 (fracture line 1 type), 41.0% of type 2 (fracture line 2 type), 30.0% of type 3 (fracture line 3 type), and 16.8% of . You have sustained a fracture to your fibula (outside ankle bone) this is classified as a stable Weber A type fracture. . Incidence and clinical relevance of tibiofibular synostosis in fractures of the ankle which have been treated surgically. They are most often caused by twisting the ankle, the circumstances of which the patient will typically recall. Lauge-Hansen Classification Based on position of ankle and direction of force applied at time of injury. Maintaining congruency of the ankle joint is therefore critical to the long-term viability of the ankle [9]. Weber classifications-Classification cannot be used for non-rotational ankle fractures. An alternative to crutches and wheelchairs. Ankle fractures can be classified according to either the AO/OTA, Danis-Weber or Lauge-Hansen classification system. The Danis-Weber classification[1](Weber classification) is a simple method for classifying fractures of lateral ankle fracturesand is based on radiographic criteria. Type C: fracture above the joint level which tears the syndesmotic . Background and aim: There is a wide debate about the number, diameter and length of the syndesmotic screw and necessity and timing for its removal. It takes into consideration the position of the distal fibular fracture in relation to the syndesmosis of the ankle joint. Add spiral or oblique distal fibular fracture (Weber C) 4. Closed Ankle Fracture. Diagnosis is made with plain radiographs of the ankle. The Lauge-Hansen classification is based on a rotational mechanism of injury. . Maisonneuve fracture refers to a combination of a fracture of the proximal fibula together with an unstable ankle injury (widening of the ankle mortise on x-ray), often comprising ligamentous injury (distal tibiofibular syndesmosis , deltoid ligament) and/or fracture of the medial malleolus. 3. - comminuted fractures of the fibula are often high energy injures resulting from direct lateral trauma or vertical loading; - comminution alters landmarks & complicates rotation and length assessment; Tibiofibular ligaments intact.

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. 1. Ankle fractures are very common injuries to the ankle which generally occur due to a twisting mechanism. Ankle is a three bone joint composed of the tibia , fibula and talus Talus articulates with the tibial plafond superiorly , posterior malleolus of the tibia posteriorly and medial malleolus medially Lateral articulation is with malleolus of fibula UMY ANKLE ANATOMY. 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. It is not required knowledge of most SHOs, but if you understand this, then . 2007), but neither of the two most widely used classification systems for ankle fractures, the Lauge-hansen (Lauge-hansen 1950) and Weber (Muller et al.

Complex Regional Pain Syndrome, also known as reflex sympathetic dystrophy, is an idiopathic condition caused by an aberrant inflammatory response that leads to sustained sympathetic activity in a perpetuated reflex arc. Topics with the highest number of questions. The Lauge-Hansen classification system was developed on the basis of the mechanism of trauma and is useful for guiding treatment. AO/Weber: Type A Malleolar Fractures. URL of Article. 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. - 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 . Symptoms include pain, swelling, and difficulty moving the affected leg and foot. There are 4 categories and 13 subgroups of ankle fractures detailed in the table below. most common in Weber C fracture patterns. 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 9:13. - Syndesmotic Injury. The Danis-Weber classification system uses the position of the level of the fibular fracture in its relationship to its height at the ankle joint. The Lauge-Hansen classification is a system of categorizing ankle fractures based on the foot position and the force applied. Traumatic or pathological injury to the ankle joint in which the continuity of an ankle bone is broken. Classification system for vertical neck fractures of the talus, the commonest type of talus fracture. E Elevation Wrap an elastic bandage from the toes to mid calf, using even pressure. The simple Danis-Weber classification looks solely at the level of the fibula fracture and its relation to the ankle mortise. Type B. Fracture at the level of the Tibiofibular ligaments. Weber B, the fracture line has a component at the level of the ankle joint The aim of this study is to determine whether functional and radiological outcomes differ in patients operated for Weber type B and C ankle fractures who had syndesmotic screws removed (group 1) compared to those who did not (group 2). References. The major symptoms are pain in the affected area and decreased range of motion. Danis-Weber classification. Type B. Closed Ankle Fracture.

This fracture involves a break in one or more of the bones that make up the ankle: the tibia (shinbone), fibula (outside ankle bone), and talus (small bone in the back part of the foot). Tibial hemimelia is a spectrum of deformity characterized by a shortened or absent tibia and relatively unaffected fibula; duplication of the great toe may be the only clinical finding in subtle deformity. Text is available . 4:50. ideally, a classification system would help physicians deter-mine the appropriate treatment method (Michelson et al. Ankle Fractures - Trauma - Orthobullets.

There were 273 patients included in the final analysis. The diagnosis as well as the treatment is usually no problem. The Salter-Harris classification of physeal fractures is the most commonly used anatomic system, because of its simplicity and the prognostic significance of each injury type. This normally takes approximately 6 weeks to unite (heal) although pain . This is usually a stable fracture. Tibiofibular ligaments intact in about 50% cases. The most commonly used Lauge-Hansen classification Summary. 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. Of the eight grades for distal radial fractures in the Frykman Classification system, half include ulnar styloid involvement. We will first give a short overview of these fractures and then discuss them in more detail. Please see the picture below to understand where this injury is. You have fractured the bone on the outside of your ankle (fibula). Diagnosis is made with plain radiographs of the ankle.
