概括
脊椎骨评分 (TBS) 可能会高估瘦身或高个体的骨质. 调整算法以适应身高和腰椎组织厚度可以提高骨评估的准确性.
科学领域:
- 整形外科和体育医学
- 放射学和成像学 放射学和成像学
- 骨密度测试 骨密度测试 骨密度测试
背景情况:
- 脊椎骨评分 (TBS) 评估骨质量,但它的算法使用体重指数 (BMI) 作为组织厚度的代理值,由于身体组成和身高的个体变化,这种指数可能不准确.
- 这种限制可能会影响不同体型的个体TBS的准确性,特别是那些瘦或高的人.
研究的目的:
- 研究TBS与年轻男性的体型和组成之间的关系,这些年轻男性的BMI正常,但体脂和身高不同.
- 确定是否结合身高和腰椎组织厚度可以增强骨评估的TBS算法.
主要方法:
- 招募了97名年轻男性 (平均年龄17.2±1.0岁),包括运动员 (滑雪跳跃者,排球运动员) 和非运动员 (对照).
- 从使用TBSiNsight软件的L1-L4双能X射线吸收度 (DXA) 扫描中确定TBS.
- 分析了TBS,身高,L1-L4软组织厚度,脂肪质量和肌肉质量之间的相关性.
主要成果:
- 在所有组中,TBS与身高和L1-L4组织厚度有负相关性.
- 多重回归分析确定身高,L1-L4软组织厚度,脂肪质量和肌肉质量是TBS的重要决定因素 (R2 = 0.587,p<0.001).
- 在TBS变异中,L1-L4软组织厚度解释了27%,身高解释了14%.
结论:
- 非常低的L1-L4组织厚度可能导致TBS高估,而高个体可能导致低估.
- 通过考虑腰椎组织厚度和身高而不是BMI在算法中,可以提高TBS对瘦身和/或高个子年轻男性骨评估的实用性.

01:09Spongy Bone
4.6K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:29Bone Disorders

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
2.1K
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...

01:16Vertebral Column: Regions and Curvature
3.8K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

01:27Compact Bone

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...
