We reviewed 13 patients with infected nonunion of the distal femur and bone loss, who had been treated by radical surgical debridement and the application of an Ilizarov external fixator. All had severely restricted movement of the knee and a mean of 3.1 previous operations. The mean length of the bony defect was 8.3 cm and no patient was able to bear weight. The mean external fixation time was 309.8 days. According to Paley's grading system, eight patients had an excellent clinical and radiological result and seven excellent and good functional results. Bony union, the ability to bear weight fully, and resolution of the infection were achieved in all the patients. The external fixation time was increased when the definitive treatment started six months or more after the initial trauma, the patient had been subjected to more than four previous operations and the initial operation had been open reduction and internal fixation.
我们回顾了13例股骨远端感染性骨不连伴骨缺损患者，这些患者均接受了根治性手术清创及应用伊利扎罗夫外固定架治疗。所有患者膝关节活动均严重受限，平均既往接受过3.1次手术。骨缺损平均长度为8.3 cm，所有患者均无法负重。外固定平均时间为309.8天。根据佩利分级系统，8例患者获得了优异的临床和影像学结果，7例获得了优异及良好的功能结果。所有患者均实现了骨愈合、完全负重能力及感染消退。当初始创伤后6个月或更长时间开始确定性治疗、患者既往接受过4次以上手术以及初次手术为切开复位内固定时，外固定时间会延长。
