Category: Trauma; Ankle Introduction/Purpose: Ankle fractures are among the most common fractures in the body and it can affect not only professional athletes but also lower activity level and sedentary patients. The standard treatment for displaced fractures is open reduction and internal fixation. Even though the management for Weber B and C fractures is well stablished in the literature, deltoid ligament repair is still debatable. Medial ligament instability is a result of deltoid ligament failure and usually leads to valgus deformity of the ankle and severe morbidity over time. The primary objective of this study is to analyze clinically and radiographically, patients with Weber C fractures and deltoid ligament injury who were submitted to fibular fracture and syndesmotic fixation, associated with deltoid ligament repair. Methods: Forty one patients who had Weber C fractures with deltoid ligament lesion from January 2013 to December 2019 had their medical records and X-Rays reviewed by a fully trained foot and ankle surgeon. The patients were between 14 and 69 years old and had their medial clear space wider than 4mm on initial X-Rays (our criteria for deltoid ligament lesion). Patients with Weber A or B, diabetics and with previous surgeries on the ankle were excluded. Patients were submitted to open anatomic reduction and fixation of the fibula, the syndesmosis was fixed with dynamic fixation system and the deltoid was reattached to the tip of the medial malleolus with one suture anchor. Medial Clear Spcace, Tibiofiluar clear space and Tibiofibular overlap were measuresd on weight bearing X-Rays done on the last follow up visit. FAAM sports Subscale17 and VR12 were used to evaluate clinical status of our patients. Results: Forty one patients were analyzed on this series after 22 months on average. The mean age at operation was 37.7 years old. There were 32 males and 9 females. Mental and Physical VR-12 scores went from 56 and 37 pre-operatively to 57 and 50 on their final evaluation. Activity Daily Living and Sports FAAM scores improved from 27 and 7 to 19 and 88 respectively. Post- operative mean medial clear space was 3mm, and mean tibio-fibular clear space was 5mm. The average tibio-fibular overlap percentage was 46%. Patient's overall satisfaction rate was 86.7%. Conclusion: Weber C fractures with Deltoid ligament lesion can be successfully treated with anatomic reduction, syndesmotic fixation (dyanamic systems) and open deltoid repairs. Patients
