Abstract

The management of infected nonunion is based on a detailed evaluation of patients, the involved bone and soft tissues, stability of fixation, and type of bacterial pathogens. Preoperative surgical planning and strategies for each step is mandatory for the successful treatment of infected nonunion. The radical debridement of infected tissues, including the unstable implant, is one of the most important procedures. Adequate soft tissue coverage should be considered for the appropriate management of infection; a reconstructive procedure and stable skeletal stabilization by internal or external fixation is also necessary later. A restoration of bone defects and bony union can be accomplished with bone grafting, distraction osteogenesis, vascularized fibular grafting, and induced membrane technique.

Fig. 3

(A) Plain X-ray taken 6 months after the injury shows delayed healing of the fracture without implant loosening. Tissue biopsy from the nonunion site revealed an infection, but there was no significant instability of the fracture, and infection was localized around the fracture site. After meticulous debridement of the infected tissue, autogenous cancellous bone graft and plate augmentation was performed.

(A) Under the diagnosis of infected nonunion, radical debridement of the infected tissue was performed and the fracture was stabilized by an external fixator.

(A) An X-rays and clinical photography taken 5 months after the injury showed infected nonunion after definite plate fixation with soft tissue defect. (B) The radical debridement of infected bone and soft tissue was carried out. The bone defect was filled by an anti-cement spacer (induced membrane technique) and soft tissue defect was covered by a free flap.
