Cable-Pin系统与克氏针张力带治疗髌骨骨折疗效的Meta分析
Effect comparison between Cable-Pin system and tension-band wiring in surgery of patellar fractures: a meta-analysis
-
摘要: 目的：通过对随机对照试验（Randomzied Controlled Trials, RCT）进行Meta分析，探讨克氏针张力带（tension-band wiring, TBW）和Cable-Pin系统（Cable-Pin system, CPS）治疗髌骨骨折的疗效差异。方法：检索中英文数据库，纳入7项相关RCTs。应用RevMan 5.3〖JP2〗对于二分类变量计算比值比 (odds ratio, OR)和95%可信区间 (confidence interval, CI)，连续变量则计算加权平均数(weighted mean difference, WMD)和95%CI。结果：Meta分析显示，TBW组与CPS组患者平均手术时间、术中失血量差异均无统计学意义；两组手术切口长度、平均骨折愈合时间、术后并发症和术后膝关节HSS 评分差异均有统计学意义（P<0.05）。结论：针对髌骨骨折，与采用TBW治疗相比，CPS疗效更好、更安全，且术后膝关节功能的改善效果更好。Abstract: Objective：To compare the effect of Cable-Pin system (CPS) and tension-band wiring (TBW) in surgery of patellar fractures by using meta-analysis of randomized controlled trials (RCTs). Methods：Seven RCTs were reviewed in this study. Odds ratio (OR) and 95% confidence interval (CI) were calculated for dichotomous data and weighted mean difference (WMD) and 95%CI were applied for continuous variables. Results：It was shown that there was no significant difference in surgery time and intraoperative blood loss between two groups.The length of incision, fracture healing time, complications and hospital for special surgery knee score after surgery were significantly different between two groups （P<0.05）. Conclusions：Compared with TBW, CPS is better and safer in treatment of patellar fractures, with better improvement on knee function.
