Purpose: We aimed to analyze the effect of fixation tightness of the syndesmotic screw and its indwelling period on therecurrence of the syndesmosis widening after screw removal and the clinical outcomes.
Materials and Methods: Forty consecutive patients with acute syndesmotic injury were retrospectively reviewed. Thetibiofibular clear space is measured by digitalized measurement tool on serial radiographs. We analyzed the effect of time fromtrauma to fixation, syndesmotic screw indwelling duration, and fixation methods. Residual symptoms at the last follow up wereevaluated. The student t-test, correlation test, and chi-square test were used for statistical analysis.
Results: Eighteen ankles (45%) had recurrent syndesmosis widening (greater than 5% compared to the contralateral side).Seven patients had pain and five had limitation of motion in the ankle joint. Fixation tightness had significant effect onreducing the recurrence while the severity of the initial widening, time to fixation, and duration of fixation did not affect theoutcome.
Conclusion: Tight fixation of syndesmotic screw is essential for achieving final syndesmotic stability and reducingrecurrence.
