Objectives: To describe the results of surgical treatment of post-traumatic segmental bone defects (PSBD) through the induction membrane technique. Material and Methods: Observational study in patients attended at Hospital Nacional Cayetano Heredia in Lima from January 2009 to June 2014, in whom a two-step reconstruction procedure for PSBD was performed using the induction membrane technique. In the first step, the formation of a membrane was induced with an antibiotic spacer block followed by replacement of the spacer with bone grafting. Time to bone consolidation, degree of shortening of the extremity, functional status and complications were recorded. Results: Twenty patients were included in the study (15 males and 5 females); mean age was 29 year (range: 13-54). Eleven cases had PSBD in the tibia, 7 in the femur, 1 in the radius and 1 in the ulna; in 90% of cases the PSBD had a length of at least 50mm (mean of 73 mm); 60% of cases had a positive culture at the beginning of treatment. Ninety percent consolidated the fracture with a single procedure in a meantime of 8 months. One patient required a second procedure and one presented a persistent infection without consolidation. Conclusions: The induction membrane technique is an efficacious procedure for managing PSBD.
