Summary
Bone quality, beyond density, includes structure and composition. New assessment techniques offer insights into fracture risk factors.
Area of Science:
- Orthopedics and Bone Biology
- Biomaterials Science
Background:
- Bone strength depends on more than just bone mineral density.
- Factors like bone turnover, microarchitecture, and mineralization significantly influence skeletal integrity.
- Understanding these factors is crucial for assessing fracture risk.
Purpose of the Study:
- To define bone quality and its components.
- To highlight the development of new techniques for assessing bone quality.
- To emphasize the importance of these assessments in understanding fracture determinants.
Main Methods:
- Review and synthesis of current understanding of bone quality.
- Discussion of emerging technologies for evaluating bone composition and structure.
- Exploration of how these methods assess microarchitecture, mineralization, and microdamage.
Main Results:
- Bone quality encompasses turnover, microarchitecture, mineralization, microdamage, and matrix/mineral composition.
- Novel assessment techniques are advancing the understanding of these bone quality aspects.
- These advancements are expected to provide deeper insights into fracture risk.
Conclusions:
- Bone quality is a multifaceted determinant of bone strength.
- Developing and applying new assessment techniques are vital for a comprehensive understanding of skeletal health.
- Improved assessment of bone quality will enhance fracture risk prediction in various disease states.

01:09Spongy Bone
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...

01:18The Bone Matrix
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
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...

01:23Bone as Supporting Connective Tissue
Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the body.
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...

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...

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
