概括
老年男性经历骨矿物质密度下降,但周骨扩张补偿,保持手术部强度. 这项研究揭示了近接骨中关键的与年龄相关的骨变化.
科学领域:
- 整形外科 整形外科 整形外科
- 老年学是一门学科.
- 骨生物学 骨生物学 骨生物学
背景情况:
- 与男性骨矿物质密度 (BMD) 和靠近腰骨的结构的年龄相关变化尚未完全理解.
- 这些变化可能会导致脆弱的骨折,强调需要详细的骨性质分析.
研究的目的:
- 研究中国男性手腕手术部骨质量,结构和几何性质的与年龄相关的变化.
- 了解这些变化如何影响骨强度和骨折风险.
主要方法:
- 在三个年龄组 (20-50,51-64,≥65岁) 中对193名中国男性进行了横截面队列研究.
- 定量计算断层扫描 (QCT) 用于评估骨质,结构和几何性质.
- 分析年龄和各种骨参数之间的相关性,包括骨质量,皮层厚度,骨髓和骨周尺寸,截面模量和面积时刻.
主要成果:
- 骨矿物质密度与年龄有着最强的负相关性.
- 骨髓和骨周扩张随着年龄的增长而发生,每十年增加直径,周长和面积.
- 尽管骨质量下降,但切口模量和面积时刻 (曲和扭转阻力指数) 与年龄有显著的线性关联,并且与年轻人相比,在老年男性中没有减少.
- 皮层厚度与年龄没有显著的相关性.
结论:
- 靠近腰椎外科手术的周骨扩张随着年龄的增长而进展,抵消BMD下降.
- 骨的几何性质对于曲和扭曲抵抗至关重要,在老年男性中由于周骨扩张而保持不变.
- 这些发现表明,手术部对骨折的抵抗力可能不会仅仅因衰老而显著受到损害.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

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...
