Nonunion of Bone Infection Mosaic External Fixator for the Treatment of Post-traumatic Tibial

目的：探讨镶嵌式外固定器用于治疗胫骨创伤所造成的感染性骨不连症状的临床价值。方法：选择20例感染性骨不连患者,8例患者以两段式固定器治疗,归为I组,12例患者以三段式固定器治疗,归为Ⅱ组,观察并比较两组中患者骨性愈合的情况。结果：术后,为两组病患实施6~36个月的随访调查,20例病患全部于治疗后的7~24个月内实现骨性愈合,骨评定与功能评定优良率均较高。本组共5例患者发生20处钉道感染,I组中1例出现再发骨髓炎,经治疗痊愈。结论：临床医师采用镶嵌式的外固定器为胫骨创伤后发生感染性骨不连症状的患者施治,可以根据骨不连的实际情况,调整长度与角度,操作简单方便,便于为骨折端进行开放换药,疗效显著,具有较高应用价值。

Objective： To explore the clinical value of the mosaic external fixator for the treatment of tibia trauma caused by infected nonunion symptoms.Method： 20 patients with nonunion of bone infection, 8 patients with two segment fixation, classified as group I, 12 patients with three segment fixation, belong to the group Ⅱ, the two groups were observed and compared in patients with bone healing.Result： The two groups were followed up 6-36 months after operation, 20 patients in all treatment after 7-24 months to achieve bone healing, bone assessment and functional assessment were higher.20 pin tract infection occurred in this group of 5 patients, 1 case in group I suffered recurrent osteomyelitis, recovered after treatment.Conclusion： The occurrence of infectious nonunion and symptomatic patients treated with external fixation device clinicians mosaic for post-traumatic tihial, according to the actual situation of bone nonunion, adjust the length and angle, the operation is simple and convenient, easy to fracture end open dressing, curative effect is distinct, has higher application value.
