Introduction: The treatment of septic pseudarthrosis of the leg requires the removal of infected bone tissue and soft tissues. Different filling techniques have been proposed. Among them, the technique developed by A.C. Masquelet in 1986 is to provide support in 2 stages with the establishment of a PMMA cement spacer that allows the development of an induced membrane. This induced membrane is used at the 2nd time as a sleeve to set up the bone graft. The main objective of our study was to evaluate our results with this technique clinically and radiologically during a series of patients supported in our department. Material and Method: Nineteen septic pseudarthroses of traumatic origin were included from November 2007 to November 2014 in this retrospective single-centric study. Patients were routinely monitored for clinical and radiological monitoring to assess the time to consolidation. A statistical evaluation of the factors that can influence consolidation has been carried out. Results. - The series included 4 women and 14 men (19 legs), the average age was 53.9 years. In 26% of the cases, a cutaneous covering procedure was required before the 1st time. All patients were operated in 2 stages with an average delay of 7.9 weeks between the 2 times. The bone defect after 1st beat was 52.4 mm on average. The bone graft was an autograft taken at the expense of the iliac crests in the majority of cases (18/19). The focus was stabilized by an external fixator, a locked plate or a plaster after the 2nd beat. The mean follow-up was 34 months with a consolidation rate of 89% (17/19) with an average delay of 16.0 months from the second gesture. After the 2nd time, 11 patients required complementary actions (average of 2.1). The importance of cutaneous opening statistically influenced the consolidation (Gustilo III vs Gustilo I or II) and tobacco was found as a factor tending to negatively modify bone consolidation.......................
