阻挡螺钉配合逆行髓内钉内固定治疗股骨远端骨折的临床研究

Clinical study of blocking screw combined with retrograde intramedullary nail internal fixation in the treatment of distal femoral fractures

目的探讨阻挡螺钉技术配合闭合复位逆行髓内钉内固定治疗股骨远端骨折的效果。方法选取2010年3月～2015年12月在我院创伤骨科收治的例股骨远端骨折患者42例作为研究对象,以随机数字表法分为观察组和对照组,各21例。对照组予以股骨远端锁定钢板内固定术治疗,观察组予以阻挡螺钉技术配合闭合复位逆行髓内钉内固定治疗,对比骨折愈合时间、膝关节功能恢复优良率、并发症发生率情况。结果观察组膝关节功能恢复优良率(95.24%)高于对照组(71.43%),差异有统计学意义(P<0.05);观察组骨折愈合时间短于对照组,并发症发生率(0)低于对照组(19.05%),差异有统计学意义(P<0.05)。结论阻挡螺钉技术配合闭合复位逆行髓内钉内固定治疗股骨远端骨折,骨折愈合良好,临床推广价值高。

Objective To investigate the effect of blocking screw technique combined with closed reduction retrograde intramedullary nail internal fixation in the treatment of distal femoral fractures.Methods A total of 42 patients with distal femoral fractures admitted to our hospital from March 2010 to December 2015 were enrolled in the study.They were randomly divided into observation group and control group,with 21 cases in each group.The control group was treated with distal femoral locking plate internal fixation.The observation group was treated with the technique of blocking screw and closed reduction retrograde intramedullary nail internal fixation.The fracture healing time,the excellent rate of knee function recovery and the incidence of complications were compared.Results The excellent rate of knee function recovery in the observation group(95.24%)was higher than that in the control group(71.43%),and the difference was statistically significant(P<0.05).The fracture healing time of the observation group was shorter than that of the control group,and the complication rate was 0 in the observation group,lower than the 19.05%in the control group.The differences were statistically significant(P<0.05).Conclusion The technique of blocking screw combined with closed reduction retrograde intramedullary nail internal fixation for the treatment of distal femoral fractures can result in good fracture healing and has high clinical value.
