    Abstract:
    PURPOSE. To review outcomes of 7 patients who underwent revision surgery for infected non-union of the humerus using a fibular graft as an intramedullary strut. METHODS. Records of 7 men aged 29 to 59 (mean, 40) years with humeral diaphyseal infected non-union who underwent fixation using a compression plate and a non-vascularised fibular graft as an intramedullary strut were reviewed. The mean number of previous surgeries was 2.7 (range, 2-4). Three of the patients had active draining sinuses previously. Their C-reactive protein levels were normal and tissue cultures negative. The remaining 4 patients had active draining sinuses. They first underwent implant removal and debridement. Tissue cultures confirmed infection in 3 of them. The mean duration between debridement and the index surgery was 5 (range, 3-10) months. RESULTS. The mean length of the fibulae harvested was 13 (range, 12-15) cm. All 7 non-unions healed. The mean time to healing was 5.4 (range, 4-8) months. The mean follow-up period was 15 (range, 13-24) months. All patients had weakness of the extensor hallucis longus, which improved to near normal at month 3. There was no donor-site morbidity. Three patients with active infection at presentation underwent repeat surgery. Two of them had wound washouts, and their non-unions went on to heal successfully; one underwent implant removal after union due to an active sinus. Six of the patients returned to their pre-injury activity level, and one endured a brachial plexus injury. CONCLUSION. Fixation using a compression plate and a non-vascularised fibular graft as an intramedullary strut achieved good outcome for infected non-union of the humerus despite prior multiple failed surgeries.
