摘　　要：目的探讨下肢骨痂延长术后并发再骨折的发生率,分析再骨折发生的相关危险因素,为再骨折的发生寻找有效的预防措施。方法回顾性分析自2005年4月—2010年11月,采用镶嵌式单臂骨外固定器行下肢骨痂延长术165例,再骨折16例,评估再骨折发生的危险因素。对再骨折患者的性别,行骨痂延长术的原因及部位,骨痂延长的长度等因素与再骨折发生的相关性进行统计学分析。结果下肢行骨痂延长术患者再骨折率为9.6%,所有病人均获得24～58个月随访,平均(32.1±7.3)个月,其中患者性别差异引起的再骨折P>0.05,差异无统计学意义;患者发病原因、发病部位及骨痂延长的距离引起的再骨折P<0.05,差异有统计学意义;同时采用Logistic回归模型分析,发现患者病因及延长距离2个变量具有独立危险性。结论利用镶嵌式骨外固定器行骨痂延长术术后并发再骨折的主要危险因素为患者自身发病原因及骨痂延长距离,治疗关键在于有效地针对再骨折的危险因素,预防再骨折的发生。Objective To study the incidence of refracture after callus distraction and explore the risk factors associated so as to find out the preventive measures.Methods 165 cases were studied retrospectively for callus distraction,16 cases were found refracture after bone union.All patients were followed up and gender and causes of morbidity and position,the length of callus distraction were evaluates.Results All the cases were healed,and followed up duration was 32 months（24～58 months）.The refracture rate was 9.6%.The causes of morbidity and position,the length of callus distraction were evaluates,and the difference was significant（P〈0.05）.Conclusion The most risk factors of refracture after dallus distraction are causes of morbidity and length of callus distraction.The a good method for radial club-hand deformity due to osteomyelitis.Treatment of the key is to effectively refracture risk factors,prevention of refracture occurred.
