To examine national estimates of forearm and wrist fractures among adults treated in US emergency departments.
The National Electronic Injury Surveillance System All Injury Program was used to estimate emergency department visits for unintentional fall related forearm and/or wrist fractures among adults aged 50 years or older between 2001 and 2007. Census population estimates were used as the denominator to calculate age-specific and age-adjusted fracture rates per 100,000 persons.
Based on 14,771 cases, an estimated 1,045,008 adults aged ≥50 years were treated in US hospital emergency departments for fall related forearm and/or wrist fractures during the study period. Of these, an estimated 832,591 (80%) fractures occurred among women. The incidence of fractures among women increased gradually with age from the age of 50 years. In men, fracture rates remained low until later in life. Between 2001 and 2007, fracture rates increased predominantly among women in the age group 50-59 years at an annual rate of 3.9% (95% CI -0.1 to 8.2).
The study indicates marked gender differences in unintentional fall related forearm and/or wrist fractures among adults aged ≥50 years treated in US hospital emergency departments. Interventions aimed at preventing falls might be effective in reducing the incidence of this injury, particularly in those women who already have diminished bone mineral.
调查美国急诊部治疗的成年人前臂和腕部骨折的全国估计数。
利用国家电子伤害监测系统全伤害项目，估计 2001 年至 2007 年期间，50 岁或 50 岁以上年龄组因非故意跌倒相关的前臂和/或腕部骨折而到急诊部就诊的人数。使用人口普查估计数作为分母，计算每 10 万人中特定年龄和年龄调整后的骨折发生率。
根据 14771 例病例，估计在研究期间，有 1045008 名年龄≥50 岁的成年人因跌倒相关的前臂和/或腕部骨折在美国医院急诊部接受治疗。其中，估计有 832591 名（80%）骨折发生在女性中。女性骨折发生率随着年龄的增长从 50 岁开始逐渐增加。在男性中，骨折率直到晚年才保持较低水平。2001 年至 2007 年期间，50-59 岁年龄组女性的骨折率每年以 3.9%的速度（95%可信区间为-0.1 至 8.2）显著增加。
该研究表明，在美国急诊部治疗的≥50 岁成年人中，与非故意跌倒相关的前臂和/或腕部骨折存在明显的性别差异。旨在预防跌倒的干预措施可能有效降低这种伤害的发生率，特别是在那些骨矿物质已经减少的女性中。
