Summary
Raman spectroscopy can assess bone quality by analyzing mineral and collagen composition, aiding in the diagnosis of fragility fractures. Further research is needed for noninvasive in vivo applications.
Area of Science:
- Bone research
- Biomaterials science
- Spectroscopy
Background:
- Fragility fracture diagnosis relies on understanding bone quality's mechanical properties.
- Raman spectroscopy is a technique used to assess bone composition changes due to aging, disease, or injury.
Purpose of the Study:
- Review Raman spectroscopy applications for bone quality assessment.
- Examine correlations between Raman spectra and biomechanical properties.
- Discuss potential for ex vivo and in vivo human measurements.
Main Methods:
- Literature search of peer-reviewed journals using "bone Raman spectroscopy" as keywords.
- Exclusion of studies on pharmaceuticals, dental tissue, tissue engineering, stem cells, and implants.
Main Results:
- Raman spectra vary with bone age, biomechanical status, and pathology in human and animal models.
- Mineral-to-matrix ratio, carbonate-to-phosphate ratio, and mineral crystallinity are supported as bone quality measures.
- Discrepancies in results stem from using band intensity ratios instead of true composition ratios, particularly with collagen bands.
Conclusions:
- Raman spectroscopy shows potential for assessing ex vivo bone quality.
- Further validation is required for ex vivo applications.
- Noninvasive in vivo Raman spectroscopy methods are still under development.

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...

01:18Classification of Bones
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 long...

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...

01:17Gross 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...

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.
