The induced membrane technique (IMT) has been widely evaluated for reconstruction of post-traumatic bone defects. However, no specific evaluation was conducted in ballistic injuries. The objective of the present study was to compare IMT in conventional trauma (CT) versus ballistic trauma (BT) managed in a military trauma center.
A retrospective study was conducted between 2009 and 2018 in patients treated by IMT for post-traumatic bone defects, whatever the defect location. Endpoints comprised bone union, residual infection, additional bone grafting and lower-limb amputation.
Thirty-six patients were included: 24 in the CT and 12 in the BT group. Demographics and injury pattern were similar in both groups, with open fracture and infected lesions predominating. The only significant difference was that tibial bone defects were larger in the BT group. Operative parameters and results were also similar. At a mean 24 months' follow-up, bone union rate was 83% in both groups, without significant differences in residual infection, complementary grafting or late amputation.
IMT is appropriate to bone reconstruction in the aftermath of ballistic trauma, with similar results to those obtained in conventional trauma.

诱导膜技术（IMT）已广泛应用于外伤性骨缺损的重建。然而，在弹道伤中尚未进行具体的评估。本研究的目的是比较诱导膜技术在常规创伤（CT）和军事创伤中心治疗的弹道伤（BT）中的应用。
对 2009 年至 2018 年间采用 IMT 治疗外伤性骨缺损的患者进行回顾性研究，无论缺损位置如何。研究终点包括骨愈合、残余感染、额外植骨和下肢截肢。
共纳入 36 例患者：CT 组 24 例，BT 组 12 例。两组患者的人口统计学和损伤模式相似，开放性骨折和感染性病变居多。唯一显著的差异是 BT 组胫骨骨缺损较大。手术参数和结果也相似。平均 24 个月的随访显示，两组骨愈合率均为 83%，残余感染、补充植骨或晚期截肢无显著差异。
IMT 适用于弹道伤后骨重建，其结果与常规创伤相似。
