Abstract：
This study investigates the impact of helmet use on the incidence of facial fractures in bicycle accidents. Analyzing data from hospitalized bicyclists between 2005 and 2016, the research focused on the correlation between helmet usage and various facial fractures. The study included 1256 bicyclists with known helmet use, among whom 277 individuals (22%) were identified with a total of 521 facial fractures. The findings revealed a significant reduction in the likelihood of facial fractures among helmeted cyclists compared with those without helmets (odds ratio, 0.65; confidence interval, 0.50-0.85; P=0.002). Specifically, the odds of sustaining fractures in the zygoma, orbit, nose, and maxilla were decreased by 47%, 46%, 43%, and 33%, respectively, among helmeted cyclists. However, helmet use did not significantly alter the odds of mandible fractures. Overall, the use of helmets in bicycling significantly lowered the risk of midface fractures but showed no notable effect on mandible fractures in severe cycling incidents.
摘要：
这项研究调查了头盔使用对自行车事故中面部骨折发生率的影响。通过分析2005年至2016年住院骑自行车者的数据，研究重点关注头盔使用与各种面部骨折之间的相关性。该研究包括1256名已知头盔使用的骑自行车的人，其中277人(22%)被确定为共521例面部骨折.研究结果表明，与没有头盔的骑自行车者相比，戴头盔的骑自行车者面部骨折的可能性显着降低（赔率比，0.65；置信区间，0.50-0.85；P=0.002）。具体来说,zygoma持续骨折的可能性，轨道,鼻子,上颌骨减少了47%,46%,43%,33%,分别,在戴头盔的骑自行车的人中。然而,使用头盔并没有显著改变下颌骨骨折的几率.总的来说,在骑自行车时使用头盔显著降低了中面骨折的风险,但在严重骑自行车事件中对下颌骨骨折没有显著影响.
