Abstract: OBJECTIVE: At present, a large number of clinical studies have confirmed that Masquelet technology is effective and safe in the treatment of infectious bone nonunion, but most studies belong to retrospective case analysis, and the sample size is small, and there is still insufficient evidence-based evidence. Meta-analysis in the effectiveness and safety of Masquelet technique in treating infectious nonunion was conducted.
METHODS: A computer was used to comprehensively search PubMed, Embase, The Cochrane Libraray, Web of Science and China Biology Medicine Database, CNKI, Wanfang, and VIP databases for randomized or non-randomized controlled trials of Masquelet technique in the treatment of infectious nonunion published from inception to May to 2020. After literature screening, data extraction, and quality evaluation according to inclusion and exclusion criteria, RevMan 5.3 software was used to perform meta-analysis of outcome indicators. 
RESULTS: (1) A total of 12 articles were included, all of which were non-randomized controlled studies. According to the MINORS scoring scale, five articles were high-quality articles and seven articles were medium-quality articles. (2) Meta-analysis showed that: compared with Ilizarov group, average postoperative healing time (MD=-9.80, 95%CI:-14.17 to -5.43), complication rate (RR=0.44, 95%CI:0.35-0.55), and medical expenses (MD=-0.70, 95%CI:-1.13 to -0.28) were statistically significant in the Masquelet group (P < 0.05). However, excellent and good rate of clinical efficacy, excellent and good rate of affected limb function, and number of operations were not statistically significant between the two groups (P > 0.05). (3) Compared with the stage I bone graft group, the Masquelet group had a significant difference in the bone healing rate (RR=1.37, 95%CI:1.15-1.62, P=0.000 4) (P < 0.05), but complication rate and infection control rate were not statistically significant between them (P > 0.05). 
CONCLUSION: Both Masquelet technique and Ilizarov technique can achieve good curative effect in the treatment of infectious bone nonunion. However, compared with Ilizarov technique, Masquelet technique has the advantages of fewer complications, shorter healing time and lower cost, and the bone healing rate is better than the first-stage bone graft. Thus, Masquelet technology is a reliable and safe treatment for infectious nonunion, but this conclusion needs more high-quality, multi-center, large-sample randomized controlled studies to further confirm.
