Introduction

Previous studies illustrate significant increases in pelvic fracture incidence; however, there is a paucity of information on the incidence of osteoporotic pelvic ring injuries based on large-scale examinations of geographically and ethnically diverse populations. This study addresses the epidemiology of osteoporotic pubic ramus fractures in the United States and details differences in incidence rates with respect to age, gender, and race.

Materials and Methods

National Electronic Injury Surveillance System (NEISS) data between 2002 and 2019 was gathered for individuals aged 60 and above presenting to U.S. emergency departments with ramus fractures. Incidence rates for ramus injuries were calculated using adjusted U.S. Census Bureau estimates of population. Fracture incidences were calculated for age, gender, and race strata.

Results

The overall incidence rate of pubic ramus fractures in the United States between 2002 and 2019 was 13.47 per 1,000,000 people 60 years and older (95% confidence limit: 9.92-17.01). The incidence of pubic ramus fractures for females in the US was 21.71 (16.08-27.34). Rates of ramus fracture increased overall (P < .001) and for both genders between the ages of 60 and 100, though the rate increase was significantly greater in females than in males (P < .001). In terms of race, incidence was highest Asian females and lowest in Native American and Pacific Islander men.

Discussion/Conclusion

: As the first national study addressing the epidemiology of ramus injuries in the United States, this work reveals these injuries comprise a significant fracture risk in the elderly. In addition, it highlights gender and ethnic strata that are more susceptible to these injuries.

美国脆性耻骨支骨折的流行病学

介绍

以前的研究表明骨盆骨折发生率显着增加；然而，基于对地理和种族不同人群的大规模检查，关于骨质疏松性骨盆环损伤发生率的信息很少。本研究探讨了美国骨质疏松性耻骨支骨折的流行病学，并详细说明了发病率在年龄、性别和种族方面的差异。

材料和方法

收集了 2002 年至 2019 年之间的国家电子损伤监测系统 (NEISS) 数据，这些数据是针对 60 岁及以上在美国急诊科就诊的支支骨折患者收集的。使用调整后的美国人口普查局人口估计来计算支损伤的发病率。根据年龄、性别和种族阶层计算骨折发生率。

结果

2002 年至 2019 年期间，美国耻骨支骨折的总发病率为每 100 万人 13.47 例 60 岁及以上（95% 置信区间：9.92-17.01）。美国女性耻骨支骨折发生率为21.71（16.08-27.34）。在 60 至 100 岁之间，无论男女，支骨折的发生率总体上都有所增加（P < .001），尽管女性的增加率显着高于男性（P < .001）。在种族方面，亚洲女性的发病率最高，美洲原住民和太平洋岛民男性的发病率最低。

讨论/结论

：作为美国第一项针对支损伤流行病学的全国性研究，这项工作揭示了这些损伤在老年人中构成显着的骨折风险。此外，它突出了更容易受到这些伤害的性别和种族阶层。
