Zur Diagnostik der lateralen Kapsel-Bandläsion des oberen Sprunggelenkes

Report about twelve patients with ruptures of the lateral ligament of the ankle joint, who were treated surgically. Before surgery positioned x-rays in anterior-posterior and lateral view were done. After anesthesia had been given, x-rays in a.p.-view were repeated, while it was attempted to “open up” the joint. In eight patients the a. p. and lateral x-rays, which were done before anesthesia, showed a lesion of the lateral ligament. In the remaining four patients the a. p. x-rays prior to anesthesia revealed nothing abnormal. In these patients pictures were taken with the same technic under anesthesia. It could be demonstrated, that the joint opened up. Strikingly the lateral x-rays in these patients confirmed a lesion of the lateral ligament even without anesthesia. On the basis of our study we prefer x-rays taken in lateral view, if a lesion of the lateral ligament of the ankle joint is suspected.
