[Contrast-enhanced diagnostics in orthopaedics].

The diagnostic competence of the orthopaedist not only allows him to perform adequate therapy concepts, but also to meet the current structural challenges, both social and health related. In addition to clinical diagnosis, machine-aided diagnosis is becoming more important due to technical advances. In this context, contrast-enhanced examination has a special place, as it has an important diagnostic advantage in difficult or unclear cases. Current improvements in the areas of phlebography, myelography, arthrography and angiography are reviewed. Indications, risks and complications as well as the technical procedure are critically discussed.
