ABSTRACT
INTRODUCTION: The induced membrane technique, first described by Masquelet, is now well standardized, but little studied in post-traumatic forearm bone defect. The main aim of the present study was to analyze consolidation rates in this indication. The study hypothesis was that the induced membrane technique provides good consolidation results. METHODS: We performed a retrospective assessment of our experience with 10 cases of induced membrane forearm reconstruction. The two main etiologies were acute trauma or treatment for non-union. Functional impact was assessed on range of motion and QuickDASH. The complications rate was also examined. RESULTS: There were 3 cases of post-traumatic bone defect, and 7 of non-union treatment, including 6 septic non-unions. Mean defect size was 4.3cm. Mean interval between induced membrane stages 1 and 2 was 3.3 months. Pure cancellous iliac bone graft was systematic. Nine of the patients showed consolidation, at a mean 9.2 months; there was 1 case of non-consolidation, but no other complications. Range of motion was satisfactory; mean QuickDASH score was 22 at a mean 50.3 months' follow-up. CONCLUSION: The induced membrane technique was reliable, reproducible and technically accessible, with good functional and radiographic results and few complications. LEVEL OF EVIDENCE: IV; retrospective study without control group.
