[Positive contrast arthrography in the diagnosis of ligament lesions in the upper ankle joint].

There are a great number of open questions in the diagnosis and the management of ligament lesions of the ankle joint. On the basis of the data of the literature and the author's experiences the advantages of the contrast arthrography of the ankle-joint may be resumed in the following: 1. No narcosis is necessary. 2. More exact determination of the site of the lesion is possible. 3. Therefore proper treatment may be chosen. 4. The incidental technical errors are more easily to be verified. (Paraarticular administration of the contrast medium is immediately demonstrable, whereas faulty observance of the prescriprions becomes not always evident from the roentgenogram). 5. No comparative roentgenograms are necessary. 6. The X-ray staff is not exposed to X-ray radiation.
