Background: There are many options to treat post osteomyelitic gaps in forearm bones. We report a pediatric series with postosteomyelitic forearm segmental defects reconstructed with fibular only graft: the non vascular fibular intramedullary bridging bone and additional grafting (FIBBAG) and the results thereof. Methods: Outcomes in 8 patients treated with fibular strut and overlay matchstick grafts were retrospectively assessed. The clinical results were expressed as forearm shortening, range of motion at elbow and wrist joint. The radiological evaluation included time to union, presence of fractures and recurrence of infection, if any. Results: The average patient age was 6 years (range, 3–12 years). The radius was involved in 6 and ulna in 2. Union occurred in all patients. The average intraoperative gap to be spanned was 5.86 cm (range, 3–14 cm). The average time for union was 6.63 months (range, 2–14 months). Two patients required additional bone grafting procedures. No graft fatigues/fractures were noted in available follow up. There was no recurrence of infection in any case. A positive ulnar variance was seen in 3 patients at follow up. Forearm shortening was a major cosmetic limitation following the procedure. Conclusions: Fibular strut and additional bone grafting (FIBBAG) is one of the viable options for reconstruction of post osteomyelitic forearm defects in children with low procedural complication rate.
