Spongy Bone01:09

Spongy Bone

4.9K
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...

Compact Bone01:27

Compact Bone

12.2K
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Classification of Bones01:18

Classification of Bones

6.1K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

5.9K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Bone Structure01:55

Bone Structure

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.

Summary
This summary is machine-generated.

Trabecular bone score (TBS) assesses bone quality and fracture risk, complementing bone mineral density (BMD). It aids in managing conditions like diabetes and corticosteroid use, with new software addressing soft tissue interference.

Area of Science:

  • Bone densitometry and osteoporosis research.
  • Medical imaging analysis and interpretation.
  • Clinical risk assessment and management.

Background:

  • Trabecular bone score (TBS) is a noninvasive measure of bone microarchitecture, indicating bone quality.
  • Low TBS is linked to degraded bone structure and predicts osteoporotic fractures independently of bone mineral density (BMD).
  • TBS has established roles in assessing fracture risk in postmenopausal women and older men.

Purpose of the Study:

  • To review the current applications and technical aspects of TBS in bone health assessment.
  • To explore the evolving role of TBS in managing various clinical conditions.
  • To highlight TBS's utility in improving fracture risk stratification and complementing BMD.

Main Methods:

  • Review of existing scientific literature on Trabecular Bone Score (TBS).
  • Analysis of TBS's technical aspects, including limitations and software developments.
  • Evaluation of TBS's performance in diverse clinical scenarios and patient populations.

Main Results:

  • TBS is valuable for assessing fracture risk, particularly when BMD readings may be misleading (e.g., in type-2 diabetes, corticosteroid use).
  • TBS complements BMD and can refine the FRAX score for improved risk stratification.
  • New TBS software aims to mitigate interference from soft tissue thickness (STT).

Conclusions:

  • TBS is a crucial tool for assessing bone quality and fracture risk, offering insights beyond BMD.
  • Its application extends to managing patients with conditions affecting bone health.
  • Ongoing technical developments promise to enhance TBS accuracy and utility.
