背景
在前面和后面的碰撞过程中，儿童被限制在前向汽车座椅中的下肢损伤的机制、碰撞特征和频谱尚未描述。
方法
我们在两个数据库中确定了在前向汽车座椅中受到限制时下肢受伤的儿童。为了确定机制，我们分析了来自碰撞伤害研究和工程网络的三个正面碰撞案例的碰撞重建。为了进一步描述碰撞和损伤特征，我们在国家汽车抽样系统（NASS）耐撞性数据系统（CDS）数据库中评估了1至4岁的前碰撞或后碰撞下肢损伤儿童。
结果
碰撞重建数据表明，下肢损伤的可能机制是腿部和前排座椅靠背之间的接触。在CDS数据库中，我们确定了15名在前向儿童座椅中下肢受伤的儿童，通常（15人中的13人）放置在后座，在正面碰撞中发生（15人中的11人）。有几个（15个中有5个）儿童坐在未系安全带或安全不当的前向汽车座椅上。损伤严重度评分变化很大（5-50）。
结论
在严重的前部或后部碰撞中，坐在前向汽车座椅上的儿童可能会因与他们前面的汽车内饰部件碰撞而造成一系列下肢损伤。碰撞现场摄影可以提供有关有受伤风险的解剖部位的有用信息，并提醒急诊科提供者可能发生的细微损伤。
BACKGROUND
The mechanism, crash characteristics, and spectrum of lower extremity injuries in children restrained in forward-facing car seats during front and rear impacts have not been described.
METHODS
We identified in two databases children who sustained lower extremity injuries while restrained in forward-facing car seats. To identify the mechanism, we analyzed crash reconstructions from three frontal-impact cases from the Crash Injury Research and Engineering Network. To further describe the crash and injury characteristics we evaluated children between 1 and 4 years of age with lower extremity injuries from front or rear impacts in the National Automotive Sampling System (NASS) Crashworthiness Data System (CDS) database.
RESULTS
Crash reconstruction data demonstrated that the likely mechanism of lower extremity injury was contact between the legs and the front seatbacks. In the CDS database, we identified 15 children with lower extremity injuries in a forward-facing child seat, usually (13 out of 15) placed in the rear seat, incurred in frontal impacts (11 out of 15). Several (5 out of 15) children were in unbelted or improperly secured forward-facing car seats. Injury Severity Scores varied widely (5-50).
CONCLUSIONS
Children in forward-facing car seats involved in severe front or rear crashes may incur a range of lower extremity injury from impact with the car interior component in front of them. Crash scene photography can provide useful information about anatomic sites at risk for injury and alert emergency department providers to possible subtle injury.
