    Abstract:
    BACKGROUND: To compare clinical outcomes of deltoid ligament repair versus syndesmotic fixation in lateral malleolus fracture combined with both deltoid ligament injury and inferior tibiofibular syndesmotic disruption. METHODS: Patients diagnosed with lateral malleolus fracture combined with both deltoid ligament injury and inferior tibiofibular syndesmotic disruption who received open reduction and internal fixation (ORIF) were retrospectively reviewed. Seventy-eight patients were enrolled into the study, including 40 patients treated with lateral malleolus fracture ORIF and trans-syndesmotic fixation, and 38 patients treated with lateral malleolus fracture ORIF and deltoid ligament repair. Basic information and pre- and postoperative radiological materials were reviewed. Visual analog pain scale (VAS) score, Olerud-Molander score, and the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale were used for evaluating pain control and functional recovery postoperatively at different time points. RESULTS: No complication was reported in both groups. In the trans-syndesmotic fixation group, all patients received syndesmotic screw removal 6-8 weeks postoperatively. The Olerud-Molander score and AOFAS Ankle-Hindfoot Scale in the deltoid ligament repair group were higher than the trans-syndesmotic fixation group 3 months after operation. No statistical difference was found between the two groups in VAS score from 1 to 12 months postoperatively. CONCLUSIONS: Lateral malleolus fracture ORIF and deltoid ligament repair is an effective method for lateral malleolus fracture combined with both deltoid ligament injury and inferior tibiofibular syndesmotic disruption. Compared with trans-syndesmotic fixation, deltoid ligament repair holds the advantage of not needing surgical removal of inferior tibiofibular screws postoperatively.
