BackgroundSegmental defects of long bones are notoriously difficult to treat. This study evaluates eight cases in which the Masquelet technique of induced membranes was used. The primary purpose was to assess the results compared to other types of bone reconstruction and share our tips and tricks to improve the outcome.MethodRetrospective study based on patient records and radiographs. Eight patients operated between 2011 and 2014 were included. Three had infected non-unions. Outcome measures were time-to full weight-bearing, time to radiographic consolidation, need for secondary bone grafting procedures and occurrence of complications.ResultsTime to full weight bearing seemed shorter in patients treated with nails. In two cases only partial radiographic consolidation was noted at the latest follow up visit. One patient needed secondary bone grafting and two limbs were malaligned. There were no amputations, no persistent infections, and no implant failures.DiscussionThe induced membrane technique is a useful tool to substitute bone loss yet consolidation time is somewhat unpredictable and prolonged non-weight bearing is required.ConclusionNailing seems to improve outcome compared to plating. It shortens treatment time, reduces the amount of bone graft needed, aligns the bone and should be considered when feasible. Further larger scale studies are welcome to throw more light into the efficacy and effectiveness of this technique.Copyright © 2015 Elsevier Ltd. All rights reserved.
