[Osteochondral fracture in the area of the ankle joint].

In diagnostic assessment of a trauma in the ankle joint region, it is important to think of a possible chondral or osteochondral fracture of the upper ankle joint, although the incidence of such fractures is relatively low. Besides the conventional diagnostic procedures, computed tomography becomes more and more important in the assessment of accidental injuries, especially with regard to chondral and osteochondral fractures.
