Tibia is the most common long bone fractured due its vulnerable subcutaneous location and most often associated with acquired complications of delayed union or non-union due to infection. Amongst the various treatment options to treat them, the Ilizarov external fixator application is considered superior due to its multiple advantages. The objective of this study was to analyse the role of Ilizarov fixation in infected tibial non-union, as well as to assess bony union and associated functional outcomes. A retrospective review was conducted for the duration between 1st January 2005 to 31st December 2016. Total of fifty-one patients with tibial non-union associated with infection who treated with the Ilizarov fixator were included in the study. Patient records were reviewed for union of bone, bone and functional outcomes and complications. The most common organism for infection was identified to be . At the time of final follow-up all patients had achieved union except two, one of whom had to undergo amputation due to non-union and sepsis. Majority of the patients had an excellent score as per ASAMI grading system for bone and function results. The most common complication noted was pin track infections. In our experience, Ilizarov external fixator is better suited for infected non-union of tibia because it can provide a stable mechanical environment, bone transport, correct deformities, and enable weight bearing and hence we recommend its use for the same.
胫骨是最常发生骨折的长骨，因其皮下位置易受损伤，且常与因感染导致的延迟愈合或不愈合等后天并发症相关。在治疗胫骨骨折的各种方法中，伊利扎罗夫外固定器因其多种优势而被认为更为优越。本研究的目的是分析伊利扎罗夫固定术在感染性胫骨不愈合中的作用，并评估骨愈合情况及相关功能结果。对2005年1月1日至2016年12月31日期间进行了回顾性研究。共有51例因感染导致胫骨不愈合并接受伊利扎罗夫固定器治疗的患者纳入本研究。对患者记录进行了骨愈合、骨与功能结果及并发症方面的审查。确定最常见的感染病原体为……在最后随访时，除2例患者外所有患者均实现了骨愈合，其中1例因不愈合和脓毒症不得不接受截肢。根据ASAMI骨与功能结果分级系统，大多数患者得分优秀。最常见的并发症是针道感染。根据我们的经验，伊利扎罗夫外固定器更适合治疗感染性胫骨不愈合，因为它能提供稳定的力学环境、骨搬运、矫正畸形，并允许负重，因此我们建议将其用于治疗感染性胫骨不愈合。
