摘　　要：Purpose:This study aims to investigate the efficacy of novel distraction support(DS)in intramedullary nailing treatment for tibial shaft fracture.Methods:The random controlled trial included adult patients with tibial shaft fractures who were treated with intramedullary nailing at the trauma center between July 2013 and December 2018.Participants were randomly assigned to either control group(n=43)or DS group(n=42)based on whether DS was used during the operation.All surgical procedures were conducted by a single,experienced surgeon.Parameters such as hospital stay,blood loss,operative time,infection,delayed union,and malalignment were recorded for assessment.Shapiro-Wilk test was used to assess normality,and the F test was adopted to measure variance homogeneity.Continuous variables were presented as mean±standard deviation and compared via independent samples t-tests.Categorical variables are expressed as percentages.The Pearson's Chi-squared or Fisher's exact test was used for categorical variables n(%).Two-sided p<0.05 indicated statistical significance.Results:A total of 85 participants were enrolled in the study.All cases achieved acceptable reduction.The operative time was significantly shorter in the DS group than in control group((75.3±10.5)min vs.(90.4±15.5)min,p<0.001).Additionally,the DS group showed lesser blood loss((60.1±27.2)mL vs.(85.4±25.4)mL,p<0.001).No significant differences were observed between the 2 groups in terms of hospital stay((9.4±2.7)days vs.(10.2±3.1)days,p=0.370),infection(3(7.1%)vs.2(4.7%),p=0.978),delayed union(2(4.8%)vs.5(11.6%),p=0.450),and malalignment(3(7.1%)vs.5(11.6%),p=0.713).Conclusion:The use of DS in intramedullary nailing surgery is effective.The application of this DS system may represent a valuable addition to future clinical practice.
