The sophistication of the implants allows the extension of the surgical indications for tibia plateau fractures. These fractures, which are often comminuted, are caused by a high velocity trauma, making treatment difficult. Objective: The aim of this study was to determine the indications for osteosynthesis of tibia plateau fractures in the orthopaedic-traumatology department of the Yalgado Ouédraogo University Hospital, in order to evaluate the results for their better management. Patients and Methods: it was a 5-year retrospective study of the records of patients with tibia plateau fracture operated and hospitalized in our department. The anatomical-clinical and therapeutic aspects collected from the complete files were analysed. A cortico-cancellous graft was performed in 67.4% of cases. The results were evaluated according to the criteria of Merle d’Aubigné and Mazas [1]. Road traffic accidents (97.4%) were the predominant etiology, involving mainly motorcycles (97.8%). Results: Spino-tuberository and uni-tuberository fractures were the most common. The average consolidation time was 12.5 weeks. One urinary infection, 3 superficial suppurations, 3 vicious calluses and 2 equipment dismantlings were the main complications. Our results were excellent and good in 91.3% and fair in 6.5%. Osteosynthesis of tibial plateau fractures provides excellent results and remains the most appropriate procedure to treat these fractures. Conclusion: reduce the operating time, modernize the technical platform, will allow stable osteosynthesis and early functional rehabilitation to optimize their results.
