Bone Defect Reconstruction (Masquelet/Ilizarov)

When nonunion is accompanied by segmental defects, insufficient bone mass after infection debridement, or bone defects formed by tumor/trauma resection, allograft or bone regeneration materials combined with internal fixation reconstruction can be considered. The decision depends on the defect length and location, soft tissue coverage and blood supply, previous treatment and infection control, material availability, and device compatibility.
