[Comparative examinations on diagnosis and therapy of fresh injuries of the exterior ligaments (author's transl)].

We are conducting a standardized investigation of injuries of the exterior ligaments, using X-ray films taken in forced extreme joint position in two planes. The advantage of this method is the comparison of the X-ray films taken while exerting a constant force. The X-ray films must be taken in two planes to permit a clear statement about the severity of the injury. It is necessary to exclude a hypermobile ankle joint by means of a comparative X-ray of the healthy limb. Adequate therapy with an elastic bandage, plaster cast or surgery based on this diagnostic method will ensure good results.
