Introduction: Fractures have become a public health issue in less developed countries. The treatment of fractures is often surgical, through osteosynthesis. With current technological advancements, the problem of osteosynthesis material quality is largely resolved. Despite the quality of the material, osteosynthesis failures still occur, indicating that there are still unresolved issues concerning the mechanical quality of the bone-material interface. The objective of our study is to analyze the causes of these failures by reporting our experience in managing osteosynthesis failures at the National Hospital of Niamey. Materials and Methods: This was a prospective study conducted at the Traumatology-Orthopedics Department of the National Hospital of Niamey, Niger, over a period of 32 months from March 1, 2022, to October 30, 2024. The study included patients of all ages admitted for osteosynthesis failure and managed in our department during the study period. The parameters studied were epidemiological, clinical, paraclinical, therapeutic, and evolutionary. Results: Over 32 months, we recorded 60 cases of osteosynthesis failures out of 620 admissions in the department, representing a frequency of 10.33%. There were 42 men (70%) and 18 women (30%), with a male-to-female ratio of 2.33. The age group of 31 to 40 years was the most represented, accounting for 33.33% of the cases (n=20). The average age was 35.13 years ± 1.3, with a range from 9 to 63 years. Road traffic accidents represented 93.34% (n=56) of the circumstances leading to the initial trauma. The fracture involved the pelvic limb in 93.33% (n=56) of cases. The initial fracture site was complex in 53.33% of cases (n=32). The most commonly used osteosynthesis material was the screw plate, used in 53.33% (n=32) of the initial osteosynthesis, followed by the external fixator in 33.33% (n=20). The failure to adhere to osteosynthesis principles was the most common factor in the occurrence of osteosynthesis fail
