Abstract

Introduction: due to its anatomy, infected pseudarthrosis in the forearm is a challenge, and there are also few publications that describe the treatment of infected diaphyseal bone loss in the radius using the Masquelet technique. The objective of reporting this case is that having a bone loss of 7 cm infected with Pseudomonas aeruginosa , we eliminate the infection and based on the importance of the diamond concept through a balance between the biological environment and absolute mechanical stability, we achieve bone consolidation and complete functionality. Case presentation: male patient, 30 years old, type 2 diabetes mellitus, hypotrophic septic nonunion of the left radius, previously treated for closed fracture, presenting a month later rejection of the osteosynthesis material with skin fistula, purulent exudate and culture for Pseudomonas aeruginosa . The treatment consisted of performing the induced membrane technique with medicated polymethylmethacrylate, application of an autologous iliac crest graft plus bone marrow aspiration, eliminating the infection, achieving
