Objective:To compare the effect of internal fixation with kirschner pins and closed manipula-tive reduction on closed fracture of radius and ulna in children.Methods:Select 86 children patients with frac-ture of radius and ulna received in some hospital during the period from September 2013 to May 2015 as the research object ,of the 86 patients,43 patients were treated with internal fixation with Kirschner pins and they were defined as the control group;the other 43 cases received closed manipulative reduction and they were defined as the,observation group,observe and compare postoperative healing and clinical efficacy of the 2 groups.Results:In observation group,36 cases clinically healed ,which accounted for 83.7%,,delayed u-nion case was 5 ,which accounted for 11.6%,the healing rate was 95.3%;in control group,25 patients clini-cally healed,which accounted for 58.1%,the case of delayed union was 9 ,which accounted for 20.9%,the healing rate was 79.0% ;fracture healing rate in observation group were significantly higher (T=14.331,P<0.05),which was statistically significant.Conclusion:Compared with closed manipulative reduction ,inter-nal fixation with kirschner pins would result in less surgical inj ury,and its fixation is more stable and there would be fewer complications,it is easy to recover,and the clinical effect is significant ,it is worthy of clini-cal promotion.%目的：对比探讨克氏针内固定与手法闭合复位治疗小儿尺桡骨闭合性骨折疗效。方法：选择某院2013年9月~2015年5月收治的尺桡骨闭合性骨折小儿患者86例作为本次研究对象,其中43例患者给予克氏针内固定治疗,设为对照组；43例患者采取手法闭合复位治疗,设为观察组,观察对比两组患者术后愈合情况以及临床疗效。结果：观察组患者临床愈合的有36例(83.7%),延迟愈合的有5例(11.6%),愈合率为95.3%；对照组患者临床愈合的有25例(58.1%),延迟愈合的有9例(20.9%),愈合率为79.0%；观察组患者骨折愈合率明显高于对照组(T=14.331,P<0.05),有统计学意义。观察组、对照组患者治疗总有效率分别为97.7%、79.1%,观察组患者临床疗效明显优于对照组(χ2=18.563,P<0.05)。结论：与手法闭合复位的治疗方法相比,克氏针内固定法手术创伤小、固定牢靠、并发症少、恢复快、临床疗效显著,值得临床推广。
