Ankle fractures frequently associate tibiofibular syndesmosis injuries, whose diagnosis allowsintraoperative treatment that can prevent mid-long term complications. There are several clinical diagnostic testsand specific projections but they are difficult to interpret and standardize. The objective of the study is to evaluatea recently described intraoperative diagnostic test. We conducted the test by intraarticular contrast injection inten patients with fractures type Weber B or C. The test was valuable in 8 cases and the result coincided with theother clinical test used. We detected a fracture in one case that had gone undetected and resulted in a changeof treatment. There were no complications. Using a reproducible, cheap and safe test, we can obtain an easilyinterpretable image that complements the rest of clinical tests to support the surgeon in the decision to fix thesindesmosis in ankle fractures.
