Observations: These were three patients, all male, whose average age was 39.3 years with a range of 28 to 49 years, who presented a septic pseudarthrosis of the leg with bone defects, following of a road traffic accident and who were treated and followed in the department between May 2019 and May 2022. The three patients were treated using the Papineau technique and their evolution was marked by total wound healing and consolidation bone after a minimum of three months.

Conclusion: septic non-union of the leg is the prerogative of young adult males, victims of road traffic accidents. The Papineau technique makes it possible to eradicate the infection and obtain bone consolidation. It has the advantage of being carried out with few resources and of being practiced in hospital structures with limited technical platforms.
