[An objective sign of the presence of a dislocation of the peroneal tendon?].

If being necessary to diagnose a rupture of the external ligaments of the ankle joint one must produce special "forced" X-rays of both ankle joints in the ap-direction in the apperature of "Scheuba". In these X-rays we found a sign , typical for the luxation of the peronaeus tendons: The rims of the ankle joint are not dislarged in the external areas but they show a significant dislargement of the distance between the malleolus externus and the processus subfibularis tali on the hurt side - the range is always more than 10 mm and in significant difference to the sane side, were we found this difference never more than 10 mm. The new objektive significant sign for the luxation of the peronaeus tendons is described and a comparison to X-rays of some persons is demonstrated.
