带锁髓内钉内固定治疗胫骨远端粉碎性骨折的效果研究

Study on Effect of Locking Intramedullary Pin in Treating Comminuted Fracture of Shin Bone Distal end

目的：探讨带锁髓内钉内固定治疗胫骨远端粉碎性骨折的效果。方法：选取2006年1月至2008年1月间在我院住院治疗的胫骨远端粉碎性骨折患者90例,随机分为观察组和对照组,观察组接受带锁髓内钉内固定治疗措施,对照组接受跟骨牵引加夹板或石膏外固定措施,随访观察两组治疗效果。结果：观察组优良率为77.78%,对照组为55.56%,两者比较差异具有统计学意义（P〈0.05）。本组患者随访12-16个月年,随访率为100%。观察组并发症发生率为4.44%,对照组为31.31%,两者并发症发生率比较差异具有统计学意义（P〈0.05）。观察组1例患者延迟愈合,1例小腿内侧皮肤坏死,其余患者均获得愈合及良好塑形。对照组患者术后并发骨质疏松5例,骨折延迟愈合4例等,其余患者均功能复位。结论：带锁髓内钉治疗胫骨远端粉碎性骨折效果好于传统复位固定,值得应用。

Objective： To investigate the effect of locking intramedullary pin in treating comminuted fracture of shin bone distal end. Method： 90 cases with eomminuted fracture of shin bone distal end in our hospital from January in 2006 to January in 2008 were divided into the observation group and control group randomly. The observation group received the treatment of locking intramedullary pin, and the eontrol group received the treatment of calcaneus skeletal traction or plaster external fixation. The effects were observed by following - up. Result： The fineness rate was 77.78% in the observation group and was 55.56% in the control group, and there was significant difference between them （ P 〈 0.05 ）. The cases were all followed - up for 12 to 16 months and the follow up rate was 100%, and the incidence rate of complication was 4.44% in the observation group and was 31.31% in the control group, and there was significant difference between them （ P 〈 0.05 ）. There was one case with delayed union, one case with cutaneous necrosis of leg wall in the observation group , and others were all healing. There were five cases with osteoporosis and four cases with delayed union in the control group , and others were all function rest. Conclusion： The effect of locking intramedullary pin in treating comminuted fracture of shin bone distal end is superior to that of tradition fixation, so it is worth being used.
