Abstract:

BACKGROUND: Bone fragility and poor bone quality due to osteoporosis are a major and increasing concern. Bone microarchitecture and microdamage, the important factors of bone quality, their detection technology and instrument have experienced a long development process.

OBJECTIVE: To give a brief introduction of the concept of the bone microarchitecture and microdamage, then to summarize the research progress of their detective methods.
METHODS: PubMed and CNKI databases were retrieved for reviews and articles related to bone microarchitecture and microdamage published from January 1990 to June 2016 using the keywords of “bone microarchitecture, bone microdamage and detect/detective/detecting” in Chinese and English, respectively. Finally a total of 65 articles were selected for overview.
RESULTS AND CONCLUISON: (1) Bulk staining is a quick and useful way to confirm and assess linear microcracks and diffuse damage. Micro-CT and confocal microscopy allow visualization at the micron scale, and are useful tools to understand the three-dimentional nature of bone microdamage. Scanning electron microscope lacks the ability to investigate large regions of microdamage, but allows users to probe in extensive details at the nano scale. (2) Ultimately, we recommend the use of multiple imaging modalities according to the experimental needs to obtain useful information about bone quality and microdamage formation, across the scales of hierarchy in bone.
