What is A New Intraoperative Measurement that Predicts Ankle Syndesmotic Joint Malreduction about?

## Category: Ankle, Trauma ## Introduction/Purpose: Distal tibio-fibular syndesmotic reduction (SR) is an independent predictor of good functional outcome following ankle surgery. Classic intraoperative fluoroscopic parameters have shown to be poor predictors of distal SR. Syndesmotic malreduction (S-MR) has been reported up to 52% of surgically treated patients. Grenier et al proposed the Anteroposterior Tibio Fibular Ratio (APTF) to evaluate normal sagittal syndesmotic anatomy, showing good interobserver agreement and high correlation between both sides in normal ankles. We propose the use of the comparative APTF index (cAPTF), calculated as the absolute difference of APTF index between the normal and surgically treated ankle, to guide intraoperative sagittal SR. The aim of this study was to determine the capability of the intraoperative cAPTF to predict S-MR. ## Methods: Prospective observational study. Patients who required syndesmotic fixation for an unstable ankle fracture and who had a contralateral healthy ankle were prospectively enrolled. Intraoperative APTF was measured under fluoroscopy in both ankles according to Grenier et al and the cAPTF was calculated. No surgeons
