Arthrographic semeiotics of traumatic capsular and ligamentous pathology of the tibiotarsal articulation

One-hundred and fifty-five patients with recent trauma were submitted to arthrography of the ankle joint in order to evaluate the actual diagnostic value of the methodology. Arthrography clearly demonstrated the single ligaments (anterior talo-fibular, calcaneal-fibular, posterior talo-fibular, and deltoid) and the capsular damage or rupture. The technical factors affecting the quality of the examinations are discussed. Arthrographic accuracy was 94.2%, with 92.7% sensitivity and 100% specificity. Arthrography of the ankle joint proved to be a quick and low-cost method providing good diagnostic results and no complications, thus allowing better preoperative planning in capsular and ligament injuries.
