目的 探讨克氏针治疗足第2-5近节趾骨骨折的临床疗效。方法 2012年6月-2014年6月，通过闭合复位经皮克氏针固定治疗足第2-5近节趾骨骨折18例，分析骨折愈合情况，骨折复位丢失情况，并发症和胼胝体发生情况。结果 本组患者完成6-40个月随访，平均22个月。所有骨折均获得临床愈合，均未发生骨折复位丢失，均未存在感染，均未发生克氏针断裂，2例克氏针脱落，均未形成足部胼胝体。结论 闭合复位经皮克氏针固定足第2-5近节趾骨骨折，固定方式可靠，效果确切。

Objective To investigate the clinical effect of using K wire to treat the proximal phalangeal fractures of lesser toes. Methods Between June 2012 and June 2014, 18 patients with proximal phalangeal fractures of lesser toes were treated with K wire, to evaluate the fracture healing, loss of fracture reduction, complications and the occurrence of the corpus callosum. Results Patients in this group were followed up for 6-40 months with an average of 22 months. All fractures were healed without loss of fracture reduction. There were no infection, no K wire breakage, 2 patients with K wire pull out and no formation of the corpus callosum. Conclusion Closed reduction and percutaneous K wire fixation to treat proximal phalangeal fractures of lesser toes were reliable and effective.
