Prospective Results of the Modified Glide Path Technique for Improved Syndesmotic Reduction During Ankle Fracture Fixation

Abstract

Background: Malreduction after syndesmotic stabilization occurs in as many as 52% of cases and has been shown to detrimentally affect clinical outcomes. We propose that the modified Glide Path technique reduces the occurrence of syndesmotic malreduction. Methods: This study is a prospective series comparing 16 patients reduced with the modified Glide Path technique with a retrospectively reviewed series of 25 patients reduced with a traditional technique using fluoroscopy and a clamp. The modified Glide Path technique consists of manual reduction of the fibula and placement of a Kirschner wire through the fibula and tibia along the transmalleolar axis. The syndesmosis can then be reduced along the glide path created by the Kirschner wire to prevent posterior or anterior malreduction. Computed tomographic scans of the repaired and contralateral ankles were obtained postoperatively to assess reduction. Results: We found a statistically significant decrease of syndesmotic malreductions using the modified Glide Path technique when compared with technique that did not use a glide path. In our study, 2 of 16 patients (12.5%) had syndesmotic malreductions using the modified Glide Path technique, compared with 11 of 25 patients (44%) with syndesmotic malreductions in the historical cohort. Conclusion: The modified Glide Path technique is a simple method for ankle syndesmotic reduction. The technique has lower rates of malreduction compared with historical methods and may be useful for most operative syndesmotic injuries. Level of Evidence: Level II, prospective cohort study.
