目的探讨胫骨骨折术后骨不连的易发因素及治疗体会。方法回顾性分析我院于2005~2013年收治的胫骨骨折术后骨不连病例共36例，探讨其骨不连的危险因素。比较再次手术治疗中使用LCP(限制接触加压锁定板)内固定组和ENT(胫骨髓内钉)内固定组的手术时间、出血量、骨愈合时间等指标，探讨两组手术方式优劣性。结果除LCP组1例患者术后1个月失访，予剔除外。余患者随访3~13个月，平均9个月，骨折部位均愈合。手术时间及出血量两项ENT组与LCP组无明显差异，术后骨折愈合时间项ENT组优于LCP组，有统计学意义。结论胫骨骨折术后骨不连使用LCP或ENT内固定手术治疗均可取得满意疗效。由于两种内固定方式的术中创伤区别不显著，而术后康复对比，ENT组较之LCP组骨愈合时间较短，可认为ENT可能更优于LCP。“,”Objective To evaluate the risk factors of postoperation tibial nonunion and to investigate experience in treatment.Methods Form 2005 to 2014,36 patients with postoperation tibial nonunion were included in this study,they were treated by doing another operation and divided into two groups:LCP (Limited contact locking compression plate)fixation or ENT (Tibial intramedul ary nail)fixation.We Compared the date of Duration of operation,bleeding volume,Duration of union Between two groups.Results Except 1 patient who was in the LCP group loss to fol ow-up 1 month after the operation,The other patients were fol owed up for 3~13 months (average 9 month),and their fracture have healed.we don’t found obvious dif erence between two groups according to the date of Duration of operation and Bleeding volume.but the Duration of union who in ENT group were statistics shorter than in LCP group.Conclusion Both LCP fixation or ENT fixation to treat postoperation tibial nonunion can achieve a satisfactory ef ect.There aren’t obvious dif erence in Surgical trauma between two ways of fixation.Compared with LCP group,ENT group took shorter time to knit ing,It might suggest that ENT fixation may be bet er than LCP fixation in treatment of postoperation tibial nonunion.
