概括
随着年龄的增长,特别是女性,骨结构发生变化,影响骨质疏松症的评估. 先进的成像揭示了骨密度和厚度的性别特异性差异,这对于骨折风险预测至关重要.
科学领域:
- 老年学是指老年学的学科.
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
背景情况:
- 骨质疏松症的评估传统上依赖于骨矿物密度 (BMD),但先进的成像技术,如状骨评分 (TBS) 和3D-DXA,可以更深入地了解骨结构.
- 与年龄相关的骨结构变化尚未完全理解,需要进一步的研究超越标准的BMD.
- 了解这些变化对于准确的骨质疏松症诊断和骨折风险分层至关重要.
研究的目的:
- 通过使用先进的成像技术,研究详细的骨结构参数与年龄相关的差异.
- 为了比较不同年龄组 (65-84岁) 的男性和女性之间的骨结构变化.
- 评估TBS和3D-DXA衍生参数在评估与年龄相关的骨质恶化中的有用性.
主要方法:
- 利用了来自Bunkyo健康研究的数据,分析了1372名参与者 (男性和女性,65-84岁) 靠近大腿骨和1053名腰椎.
- 评估的参数包括TBS,体积 BMD (脊椎,皮质,整体),皮质厚度和使用 3D-DXA (3D-Shaper) 的表面 BMD.
- 用户使用Kruskal-Wallis测试与Bonferroni校正进行年龄组比较 (65-69岁,70-74岁,75-79岁,80-84岁).
主要成果:
- 男人仅在近端大腿皮层厚度显著下降,特别是在最年长的年龄组 (80-84岁).
- 妇女在所有测量参数,包括皮质厚度,皮质表面/体积BMD和状体积BMD,特别是在80-84岁年龄组中,均出现显著下降.
- 在70-74岁和80-84岁的女性中,椎骨分数 (TBS) 显著下降,但在男性中没有观察到显著变化.
结论:
- 在与年龄相关的骨结构变化中存在显著的性别特异.
- 与男性相比,女性在骨参数的恶化更为普遍,男性主要表现出皮层厚度的减少.
- 这些发现强调了在骨质疏松症评估和骨折风险预测中需要性别特定策略.

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...

01:09Changes in the Appendicular Skeleton with Age
2.4K
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...

01:20Introduction to the Skeletal System
7.0K
The skeletal system is the central framework of the body, consisting of different connective tissues: bones, cartilage, tendons, and ligaments.
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

01:17Hormones and Bone Tissue
3.0K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
