概括
过去跌倒的预测价值对于女性未来关节骨折的预测价值随着年龄的增长而下降. 这一发现表明,尽管老年女性的骨折风险较高,但预防跌倒的策略可能对老年女性不那么有效.
科学领域:
- 老年学是一门学科.
- 流行病学 流行病学
- 骨健康 骨健康 骨健康
背景情况:
- 过去一年内跌倒的病史与部骨折的风险增加有关.
- 在女性中观察到跌倒史和年龄之间的相互作用,老年女性的危险比率 (HR) 较低.
研究的目的:
- 为了确定由于不同年龄组的女性中跌倒风险增加而导致关节骨折的人口归因风险 (PAR).
主要方法:
- 按年龄层计算骨骨折的跌倒史相关可归因风险 (AR),使用先前计算的HRs.
- 50岁及以上女性部骨折的计算PAR,考虑人口中过去跌倒的比例.
主要成果:
- 分析了40个队伍中的606,715名女性的数据.
- 堕落者的比例随着年龄的增长而增加 (从50-54岁的24.6%到90-94岁的45.5%).
- 由于跌倒而导致的关节骨折的归因风险 (AR) 和人口归因风险 (PAR) 随着年龄的增长显著下降,从50-54岁妇女的54.8%的AR和23.9%的PAR降至90-94岁妇女的8.3%的AR和3.9%.
结论:
- 过去的跌倒对女性未来关节骨折的预测值随着年龄的增加而显著下降.
- 预防跌倒的策略可能在老年妇女减少关节骨折的效果较低,尽管他们的整体风险较高.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
