Current Osteoporosis Reports
|July 23, 2005
Summary
Bone quality, not just bone density, is crucial for assessing osteoporosis and fracture risk. New technologies are improving our understanding of bone strength and fragility.
Area of Science:
- Orthopedics and Bone Biology
- Biomedical Engineering
- Gerontology
Background:
- Osteoporosis is currently defined by bone density, but this metric has limitations in predicting fracture risk.
- Bone densitometry does not capture crucial bone quality aspects contributing to skeletal strength.
- Treatment trials with antiresorptive agents highlight bone density's inadequacy as a surrogate for bone fragility.
Purpose of the Study:
- To review recent literature on bone quality and its significance in osteoporosis.
- To discuss the limitations of bone densitometry in assessing fracture risk.
- To explore emerging technologies and their role in understanding bone health.
Main Methods:
- Literature review of recent publications on bone quality, osteoporosis, and fracture risk.
- Analysis of findings from treatment trials of antiresorptive agents.
- Discussion of new technologies for assessing bone microstructure, matrix composition, and biomechanical properties.
Main Results:
- Bone quality encompasses properties beyond density that determine bone strength.
- Bone density is a flawed surrogate for bone fragility and a weak predictor of antifracture efficacy.
- Bone turnover is increasingly recognized as a critical factor in fracture risk assessment.
Conclusions:
- A redefinition of osteoporosis may be necessary, shifting focus from bone density to bone turnover.
- Advanced technologies are enhancing our understanding of bone 'damageability' and its long-term effects.
- Emphasizing bone quality is essential for a more accurate assessment of osteoporosis and fracture risk.

Bone 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.
Bone 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...

Gross Anatomy of Bone
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 adults, it...

The 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...
Bone 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...

Spongy 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...
