Introduction: The treatment of osteoarticular affections of ankle can use several chirurgical methods such as the conservative treatment but also arthrodesis that’s a radical surgery. The objective is to study ankle arthrodesis in the orthopedic-traumatology surgery department of Centre hospitalier Universitaire Yalgado Ouedraogo Methods: we conducted a retrospective study from january 1,2018 to may 31, 2024. The study included patients who underwent ankle arthrodesis in orthopedic-traumatology surgery department of CHU-YO. Results: A total of 21 patients were included, 16 men and 5 women. The average age was 37.38 years. Most patients were involved in commerce (33.33%). All patients were admitted due to post-traumatic conditions with 90% resulting from road accidents. Radiographs showed signs of arthrosis in 52.38%, bimalleolar fracture sequelae being the main bone lesions at 61.9%. Post-traumatic arthrosis was the primary indication for surgery (47.6%) following by malunion and pseudarthrosis. All patients underwent tibio-talar arthrodesis, with the Meary technique used in 57.14% of cases. The anterolateral approach was the most common incision (42.87%). More than half patients (52.38%) received bone grafting, with an average plaster immobilization of 6.9 weeks. Postoperative recovery was uneventful for 71.43% of patients while 9.52% of patients required revision surgery due to pseudoarthrodesis. Only 16.67 % were dissatisfied with the operation. According to the Duquennoy score, functional outcomes were excellent in 16.67%, good in 50%, fair in 25% and poor in 8.33% of cases Conclusion: Based on these outcomes, ankle arthrodesis can be considered as a reference surgical procedure for restoring function and relieving pain, especially when conservative treatments prove ineffective.
