Reconstruction of Long Bone Infections Using the Induced Membrane Technique: Tips and Tricks

The management of posttraumatic long bone osteomyelitis remains a challenging clinical problem. A systematic approach is necessary, beginning with eradication of the infected bone and soft tissue. There are a number of options for reconstruction of the remaining bone defect, including the induced membrane technique developed by Masquelet. We describe our technique for the 2-stage treatment of long bone osteomyelitis. The first stage involves a radical debridement, stabilization of the bone with either external fixation or an antibiotic-coated intramedullary nail, and placement of a polymethylmethacrylate spacer. The second stage includes excision of the spacer and placement of autologous bone graft. Various resection methods, fixation strategies, antibiotic additives, and types of bone grafts or substitutes can be used. The purpose of our technical article is to share our personal experience and describe several nuances that are critical for the success of this treatment strategy.Level of Evidence:Therapeutic Level IV.
