Low-trauma fractures of elderly women are a major public health concern.
We determined the current trend in the absolute number and incidence (per 100,000 persons) of fresh low-trauma fractures of the proximal humerus among 80-year-old or older Finnish women by taking into account all women who were admitted to Finnish hospitals for primary treatment of such a fracture between 1970 and 2015.
The number of low-trauma fractures of the proximal humerus among 80-year-old or older Finnish women rose continuously between 1970 (32 fractures) and 2015 (568 fractures), whereas the age-adjusted fracture rate (showing a clear rise from 87 fractures per 100,000 persons in 1970 to 304 fractures in 1995) became stabilized between 1995 and 2015 (297 fractures per 100,000 persons in 2015).
The clear rise in the incidence of low-trauma proximal humeral fractures in Finnish elderly women from early 1970s until mid 1990s has been followed by stabilized fracture rates. Reasons for this are largely unknown, but a cohort effect toward a healthier aging population with improved functional ability, as well as measures to prevent falls and alleviate fall severity, could partly explain the phenomenon.
老年女性的低创伤骨折是一个重大的公共卫生问题。
我们通过纳入1970年至2015年间因近端肱骨新鲜低创伤骨折而入住芬兰医院接受初次治疗的所有女性，确定了80岁及以上芬兰女性近端肱骨新鲜低创伤骨折的绝对数量和发病率（每10万人）的当前趋势。
1970年（32例骨折）至2015年（568例骨折）期间，80岁及以上芬兰女性近端肱骨低创伤骨折的数量持续上升，而年龄调整后的骨折率（从1970年的每10万人87例骨折明显上升至1995年的304例骨折）在1995年至2015年期间趋于稳定（2015年为每10万人297例骨折）。
从20世纪70年代初到90年代中期，芬兰老年女性低创伤近端肱骨骨折的发病率明显上升，随后骨折率趋于稳定。其原因很大程度上尚不清楚，但对功能能力改善的更健康老龄化人群的队列效应，以及预防跌倒和减轻跌倒严重程度的措施，可能部分解释了这一现象。
