Tibia-fibular syndesmosis injury occurs in a significant proportion of ankle injuries and is assumed to disrupt the syndesmotic ligaments.
The goal of operative treatment is to reduce the ankle mortise to restore normal joint kinematics. Syndesmosis repair can be performed using either open or closed reduction, combined with fixation between the distal tibia and fibula. Closed fixation has demonstrated high rates of non anatomic reductions greater than 40%; therefore, open reduction will be performed in this study. Screw fixation is stable but concerns exist regarding potential excess rigidity.
Recently, flexible fixation techniques combined with anatomic reduction have demonstrated improvements in functional outcomes and reduction quality. Both open reduction and flexible TightRope fixation have considerable support in the literature in cohort studies but have not been compared to open screw fixation in a randomized controlled trial.
In this multi centre randomized study, radiographic, economic and functional outcomes are compared between [open reduction, flexible Tightrope syndesmosis fixation (OT)] and [open reduction screw fixation (OS)] of the syndesmosis.
