Following a car accident, this patient is hospitalized for a complex fracture of the lower third of the femur. The non union confirmed, a re-intervention with removal of the material, anatomical reduction, new osteosynthesis with a screw-plate plate [1-2] and grafting of a biomaterial [3-5] is practiced. Consolidation is achieved in four months. The femoral shaft is anatomically reconstructed in one year. There were no sequelae. Follow-up is three years. The essential role of vascularization is underlined. This result supports more than 300 femoral fractures treated using the same modus operandi.
