We retrospectively evaluated the outcome of fibula grafts in upper limb post infectious diaphyseal gap nonunions and assessed the following modifiers: age, site, vascularised/ nonvascularised, and length of the graft on time to union, graft incorporation, complication rate and reoperation rate. Thirty seven paediatric upper limb segmental defects treated over a period of 10 years were identified. Twenty two post septic defects in 21 children were treated with intramedullary fixation and vascularised/ nonvascularised fibula grafting. Union time was assessed from records and radiographs. Graft incorporation was assessed using Pixel value ratio (Hazra et al). Complications were defined as nonunion, delayed union, implant failure, refractures, graft loss and infection.Purpose
