摘要
目的评价单臂外固定延长支架下采用骨内移位技术治疗胫骨感染性骨不连的临床结果及功能情况。方法回顾性分析了2003年6月至2005年10月28例胫骨感染性骨不连患者的临床资料。其中23例开放性胫骨骨折,ⅢA型5例,ⅢB型11例,ⅢC型7例;内固定后感染5例。根据改良的ASAMI评定标准进行骨具体内容和功能结果评定。结果所有患者均获得随访,平均随访时间16个月。所有骨折获得初期愈合,感染均得到控制,骨折愈合时12例仍有局部窦道和渗液,治疗后软组织愈合。骨评定结果优14例,良9例,中等2例,差3例;功能评定结果优10例,良13例,中等2例,差3例。牵引成骨的平均形成长度为6.6cm,平均愈合所需时间为9个月。最常见的并发症为针道感染,2例在外固定支架拆除后对接点再骨折。结论对于胫骨感染性骨不连,使用单臂延长外固定支架通过骨内移位技术治疗是一种良好的方案。
Objective To evaluate the clinical and functional outcomes of infected nonunion of the tibia by internal bone transport using the LRS mono-lateral external fixation. Methods From June 2003 to October 2005, twenty-eight patients who underwent intemal bone transport for infected nonunion in the tibia were reviewed. Twenty-three cases were open fractures： grade Ⅲ A, 5 cases; grade Ⅲ B, 11 cases; grade Ⅲ c, 7 cases. The other five cases were infected nonunion after internal fixation. The results were evaluated by the classification of the Association for the Study and Application of the Method of Ilizarove （ASAMI） which divied into bone and functional categories. Results Mean follow-up was 16 months. All the cases got primary bone union, and infection was controlled. Bone results were 14 excellent, 9 good, 2 fair and 3 poor. And functional results were 10 excellent, 13 good, 2 fair and 3 poor. The mean length of time in healing for all patients were 9 months. The mean length of regenerate bone were 6. 6 cm. The most common complication was pin infection, and 2 cases refractured at the docking site. Conclusions Tihial infected nonunion can be successfully treated using the internal bone transport technique.
