改良克氏针张力带法治疗A型和B 2型掌骨干骨折的效果观察

Observation Effect on Modified Kirschner Wire and Tension Band Fixation for the Treatment of A Type and B 2 Type Hand to Bone Fracture

目的 探讨改良克氏针张力带法治疗A型和B 2型掌骨干骨折的临床效果。方法 选取2010年6月-2013年6月我院收治的100例A型和B 2型掌骨干骨折患者,按就诊顺序号分为对照组和观察组,每组各50例。对照组采用传统克氏针张力带法治疗,观察组采用改良克氏针张力带法。观察两组骨折愈合时间及并发症发生情况。结果所有患者随访3-12个月（平均4.5个月）。观察组骨折愈合时间为（4.5±1.6）周,短于对照组的（8.2±1.4）周;对照组骨延迟愈合、骨不连7例（14%）,感染6例（12%）。观察组骨延迟愈合、骨不连1例（2%）,感染5例（10%）。观察组并发症发生率低于对照组,P〈0.05,差异具有统计学意义。结论改良克氏针张力带法治疗A型和B 2型掌骨干骨折可促进骨折愈合,减少术后并发症,疗效显著。

Objective To explore the clinical effect on modiifed Kirschner wire and tension band fixation for the treatment of A type and B 2 type of metacarpal shaft fracture. Methods Selected 100 cases with type A and type B 2 of metacarpal fractures from June 2010 to June 2013 in our hospital. According to the order number was divided into control group and observation group, each group of 50 cases. The control group used the traditional Kirschner wire and tension band ifxation treatment, observation group were treated with modiifed Kirschner wire and tension band ifxation. Observations two groups of fracture healing time and the incidence of complications. Results All patients were followed up for 3 to 12 months, In observation group, the fracture healing time was （4.5 ±1.6）weeks, shorter than that of control group （8.2±1.4）weeks;In the control group, 7 cases （14%） were delayed union and 6 cases （12%） were infected. In the observation group, 1 cases （2%） were delayed union and 5 cases （10%） were infected. The incidence of complication in observation group was lower than that in control group, P〈0.05, had difference statistically signiifcance. Conclusion The modified Kirschner wire and tension band fixation for type A and type B 2 can promote the healing of the fracture of metacarpal shaft fracture, reduce the postoperative complications, curative effect.
