Syndesmosis assessment in postoperative patients subjected to surgical treatment of supra-syndesmotic fracture

Keywords: Ankle, Ankle joint, Ankle injuries

Abstract

Objective: To demonstrate the patterns of syndesmosis reconstruction in ankle fractures via the measurement of pre-established and universally accepted parameters. Methods: In a retrospective study, fractures with radiographic images obtained during the postoperative period showing fixation of the distal tibiofibular syndesmosis were selected. After this selection, fracture reduction and syndesmosis fixation were evaluated by measuring radiographic parameters in the selected cases. Results: Twenty-three patients (63.8%) were male. Fourteen fractures (38.8%) were operated on by a senior surgeon (foot and ankle specialist). All syndesmoses were fixed with only 1 screw, and 35 patients (97.2%) had syndesmosis fixation involving 3 cortices. The mean syndesmosis fixation height from the articular surface was 2.20cm. Four fractures (11.1%) presented radiographic signs of medial ligament reconstruction. Regarding measurement of the tibiofibular space, in the anteroposterior (AP) view, 33 patients (91.6%) had values within the normal range. Regarding the tibiofibular overlap, in the AP view, 19 patients (52.7%) had measurements with values greater than 10mm (normal). In the evaluation of tibiofibular overlap, in the true AP view, all patients (100%) presented measurements greater than 1mm (normal). Regarding the measurement of the talocrural angle, only 1 patient did not have normal parameters. Regarding the medial clear space, only 2 patients (5.5%) had values above normal during the postoperative period. Conclusion: The adoption of objective parameters, in a standardized manner and relative to the contralateral side, adds additional value to the evaluation and ensures an accessible and reproducible method for the evaluation of these injuries. Level of Evidence II; Prognostics Studies; Retrospective Study.
