[Arthrographic diagnosis of rupture of the anterior syndesmosis of the upper ankle joint].

We describe 114 cases based on 2020 arthrographies of the ankle joint for diagnosing fresh tears of the tibio-fibula syndesmosis without bone lesions. Comparison of the arthrographical diagnosis with the intra-operative diagnosis showed good agreement. Diagnosis of the isolated tear of the tibio-fibular syndesmosis revealed a sensitivity of 90% and a specificity of 67%. The technical procedure and the isolated tear of the tibiofibular syndesmosis in combination with other capsuleligament lesions are presented, using typical x-ray images as examples.
