In 1950, Lauge-Hansen devised a classification of ankle fractures based on the position of the foot and the deforming force at the time of injury. This has been widely accepted by orthopedists, but is not in general use by radiologists. An algorithm based on his classification that allows rapid assessment of the mechanism of injury in 90%-95% of cases has been devised by the authors. Identification of the fractures and classification of the type of injury allows diagnosis of the otherwise occult ligamentous injuries. On the basis of location and appearance of the fibular fracture, the four types of injuries are immediately identified: pronation-abduction, pronation-lateral rotation, supination-adduction, and supination-lateral rotation. Subsequent assessment for medial malleolar fracture and then posterior malleolar fracture defines the stage of completeness of the injury and localizes the sites of ligamentous disruption.
1950年，劳格 - 汉森根据足部位置和受伤时的致伤力设计了一种踝关节骨折分类法。这一分类法已被骨科医生广泛接受，但放射科医生一般并不常用。作者们基于他的分类法设计了一种算法，该算法能在90% - 95%的病例中快速评估损伤机制。识别骨折及损伤类型有助于诊断原本隐匿的韧带损伤。根据腓骨骨折的位置和形态，可立即识别出四种损伤类型：旋前 - 外展型、旋前 - 外旋型、旋后 - 内收型和旋后 - 外旋型。随后对内踝骨折以及后踝骨折进行评估，可确定损伤的完整程度阶段，并定位韧带断裂部位。
