Die Diagnostik der Bandverletzungen im Bereich des oberen Sprunggelenkes

On the basis of history and clinical findings it is attempted to stage a trauma of the ankle joint according to the genetic classification of Lauge-Hansen. This procedure is understood as a prophylactic measure against overlooking combined ligamentous lesions. Tears of the lateral collateral ligaments of the ankle are proven by stress roentgenograms taken in varus tilt position; they are performed by a specially developed method. Additionally stress roentgenograms are taken, when the talus is moved forwards (“anterior drawer sign”). Lesions of the deltoid ligament are shown by talar tilt in valgus position. Isolated tears of the anterior tibiofibular ligament can be visualized only by arthrography. If stress roentgenograms cannot confirm the clinical diagnosis, an arthrography is necessary.
