外固定架联合抗感染活性骨治疗下肢创伤性骨髓炎

Treatment of the Traumatic Osteomyelitis Using External Fixator Cooperate with Anti-Infective Reconstituted Bone Xenograft

目的:验证外固定架联合抗感染活性骨(ARBX)治疗下肢创伤性骨髓炎的疗效。方法:25例下肢创伤性骨髓炎患者给予原内固定取出、病灶清除、断端修整、抗感染活性骨植骨、外固定架固定,通过长期随访,分析评价其疗效。结果:随访2-10年,平均6年,感染彻底控制无复发23例,感染治愈率92%;骨不连、骨缺损获得骨性愈合24例,1例残留骨不连,愈合时间6-24月,骨性愈合率96%。结论:外固定架联合抗感染活性骨是治疗下肢创伤性骨髓炎的安全有效手术方法。

Objective： To study the effect of external fixator cooperation with ARBX treatment of traumatic osteomyelitis.Methods： 25 patients with lower limbs traumatic osteomyelitis,who were treated by taking out internal fixation,debriding infection lesions,napping cut ends,grafting ARBX and fixing external fixator,through the long-term following up,analyze its curative effect.Results： A retrospective study was done for the 25 cases who had been followed up for an average of 6（2 to10）years.The infection were cured without recurrence in 23 cases,the recovery rate of infection is 92%.Bone non-union and bone defects were cured in 24 cases except 1 case with bone nonunion,the bony union time is from 6 months to 24 months,the recovery rate of bony union is 96%.Conclusion： External fixator cooperation with ARBX are save and effective to treat lower limps traumatic osteomyelitis.
