[Does performance of a stress roentgen image of the upper ankle joint in acute fibular capsule ligament lesion entail an operation? An experimental study].

In an experimental study the sequelae of performing stress films on the ruptured lateral ligaments of the ankle joint are documented. It is shown that stress films may cause further damage on the ankle capsule when there is ligamentous disruption. After performance of stress studies a sufficient realignment of the interrupted ligaments by immobilization of the foot in a neutral (right angle) position can not be achieved. This makes, at least for younger patients, operative therapy after positive stress films advisable.
