IntroductionTo date, the management of critical-sized bone defects lacks a universally accepted approach among orthopedic surgeons. Currently, the main options to treat severe bone loss include autologous grafting, free vascularized bone transfer, bone transport and induced-membrane technique. The purpose of this study is to critically compare the outcomes of Masquelet technique and bone transport to provide a higher level of evidence regarding the indexed techniques.Material And MethodsThe authors conducted a systematic search on several databases according to the PRISMA guidelines. English-written reports comparing outcomes of the Masquelet technique versus the bone transport technique in patients with critical-sized defects in lower extremities were included.ResultsSix observational studies involving 364 patients were included. The systematic review and meta-analysis of pooled data showed no significant difference in most outcomes, except for ASAMI bone outcomes and residual deformity, which showed better results in the bone transport group. The 64% of patients treated with Masquelet technique obtained excellent/good bone ASAMI results compared to 82.8% with bone transport (p = 0.01). Post-operative residual deformity was 1.9% with the bone transport method versus 9.7% with the Masquelet technique (p = 0.02).ConclusionsBoth the Masquelet technique and bone transport showed comparable results for the management of critical-sized bone defects of the lower limb. However, these findings must be carefully interpreted due to the high risk of bias. Further prospective randomized controlled trials are necessary to better clarify the strengths and limitations of these two techniques and to identify the variables affecting the outcomes.© 2023.
