The correlation between flexion-distraction injuries and lap-belt use has been well documented. Over a 10-year period, we identified seven children admitted to Children's National Medical Center, Washington, DC, with compression fractures of the lumbar spine secondary to lap-belt use. Four were rear seat passengers, and three were in the front seat. The average age was 7 years. Four of the seven (57%) suffered associated abdominal injuries. One died of an associated head injury. We hypothesize that the mechanism of injury in these cases was similar to that in flexion-distraction injuries. The increased elasticity in the posterior ligamentous complex in children may be responsible for the occurrence of these compression fractures rather than the expected flexion-distraction-type injuries.
屈曲-牵张损伤与安全带使用之间的相关性已有充分记录。在10年期间，我们确定了7名入住华盛顿特区儿童国家医疗中心的儿童，他们因使用安全带而导致腰椎压缩性骨折。其中4名是后排乘客，3名在前排座位。平均年龄为7岁。7名儿童中有4名（57%）伴有腹部损伤。1名儿童因相关头部损伤死亡。我们推测这些病例的损伤机制与屈曲-牵张损伤相似。儿童后韧带复合体弹性增加可能是这些压缩性骨折发生的原因，而非预期的屈曲-牵张型损伤。
