While multiple studies have examined amputations that have occurred during the current conflicts in Iraq and Afghanistan, none of these studies have provided an overarching characterization of all of these injuries.
A retrospective study of all major extremity amputations sustained by US Service Members from January 2001 through July 30, 2011, was performed. Data obtained from these amputees included amputation level(s), mechanism of injury, time to amputation, Injury Severity Score (ISS), age, rank, number of trauma admissions, and number of troops deployed.
There were 1,221 amputees who met inclusion criteria. These amputees sustained a total of 1,631 amputations. The number of amputations performed each year has increased dramatically in 2010 (196) and the first half of 2011 (160) from 2008 (105) and 2009 (94). The number of amputations performed per every 100 traumatic admissions (3.5-14) and the number of amputations per 100,000 deployed troops (2-14) has also increased in 2010 and the first half of 2011. Most amputations occurred at the transtibial (683, 41.8%) and transfemoral (564, 34.5%) levels. Thirty percent of the amputees (366) sustained multiple amputations, and 14% of all amputations (228) performed involved the upper extremity. There were 127 amputees (10%) who underwent their amputation more than 90 days after the date of injury.
The number of amputations occurring during the current Iraqi and Afghanistan conflicts has increased in 2010 and the first half of 2011. Most amputations involve the lower extremities, and there is a much higher percentage of amputees who have sustained multiple amputations during current operations than previous conflicts.
Epidemiologic study, level IV.
虽然有多项研究对伊拉克和阿富汗当前冲突期间发生的截肢事件进行了调查，但这些研究都没有对所有这些伤害进行全面的描述。
对 2001 年 1 月至 2011 年 7 月 30 日期间美国现役军人因伤截肢的所有主要肢体进行了回顾性研究。从这些截肢患者中获得的数据包括截肢部位、受伤机制、截肢时间、损伤严重程度评分（ISS）、年龄、军衔、创伤入院次数和部署人数。
共有 1221 名符合纳入标准的截肢患者。这些患者共接受了 1631 次截肢手术。2010 年（196 例）和 2011 年上半年（160 例）每年的截肢例数与 2008 年（105 例）和 2009 年（94 例）相比显著增加。每 100 例创伤入院的截肢例数（3.5-14 例）和每 10 万部署部队的截肢例数（2-14 例）在 2010 年和 2011 年上半年也有所增加。大多数截肢发生在胫骨（683 例，41.8%）和股骨（564 例，34.5%）部位。30%的截肢患者（366 例）遭受了多次截肢，14%的截肢（228 例）涉及上肢。有 127 名（10%）截肢患者的截肢时间超过受伤日期后 90 天。
当前伊拉克和阿富汗冲突期间发生的截肢数量在 2010 年和 2011 年上半年有所增加。大多数截肢涉及下肢，与以往冲突相比，目前行动中遭受多次截肢的截肢患者比例要高得多。
