Despite a high prevalence in the pediatric trauma population, there remains a lack of large population-based epidemiological studies on pediatric pelvic fractures. Using a de-identified national clinical registry, we investigated the epidemiological features of pediatric pelvic fractures. We performed a retrospective analysis of data obtained from the IBM Watson Health Explorys Platform (Armonk, NY). From all children ages 0-14, two cohorts were created, children diagnosed with a traumatic injury and children diagnosed with a fracture of the pelvis. We then calculated the overall incidence of pelvic fractures, mortality rate, and identified common associated injuries, fracture locations, and complications. 2,690 pediatric pelvic fractures were identified yielding an incidence of 9.8/100,000 children per year with a mortality rate of 0.3%. Pelvic fractures were more common among Caucasians than in African Americans and Asians, and more common in males than females. The most common types of pelvic fracture were fractures of the ilium (42%), pubis (18%), sacrum (11%), ischium (10%), and acetabulum (8%). Most common associated injuries included injury of the lower extremity (43%), intracranial injury (16%), chest injury (13%), injury of the abdomen (9%), and urogenital injury (3%). Rates of common complications associated with malunion were low back pain (10%), acquired leg length discrepancy (1%), and acquired scoliosis (0.3%). The current incidence of pediatric pelvic fracture is 9.8/100,000 children per year with a mortality rate of 0.3%. Further study utilizing large data sets may help to better understand associated injuries, risks of poor outcomes, and optimize treatment strategies.

尽管儿童骨盆骨折在儿童创伤人群中发病率很高，但仍然缺乏基于人群的大规模流行病学研究。我们利用去识别化的国家临床登记系统，调查了儿童骨盆骨折的流行病学特征。我们对从 IBM Watson Health Explorys Platform（纽约州阿蒙克）获得的数据进行了回顾性分析。针对 0-14 岁的所有儿童，创建了两个队列：诊断为外伤的儿童和诊断为骨盆骨折的儿童。然后，我们计算了骨盆骨折的总体发生率、死亡率，并确定了常见的相关损伤、骨折位置和并发症。已发现 2,690 例儿童骨盆骨折，每年发病率为 9.8/100,000 名儿童，死亡率为 0.3%。骨盆骨折在白种人中比非裔美国人和亚洲人更常见，并且男性比女性更常见。最常见的骨盆骨折类型是髂骨（42%）、耻骨（18%）、骶骨（11%）、坐骨（10%）和髋臼（8%）骨折。最常见的相关损伤包括下肢损伤（43%）、颅内损伤（16%）、胸部损伤（13%）、腹部损伤（9%）和泌尿生殖系统损伤（3%）。与畸形愈合相关的常见并发症有腰痛（10%）、获得性腿长差异（1%）和获得性脊柱侧凸（0.3%）。目前儿童骨盆骨折的发病率为每年9.8/10万儿童，死亡率为0.3%。利用大数据集进行进一步研究可能有助于更好地了解相关损伤、不良结果的风险，并优化治疗策略。
