| [ Summary ] | Evaluation of bone strength is important for assessment of fracture risk. However, it is difficult to assess bone mechanical properties directly in vivo. Mechanical braking tests including compression and the three point bending test for excised bone are conventional methods for assessment of bone mechanical properties. Recently, dynamic mechanical analysis (DMA)， which is a nondestructive method, has been utilized to characterize bone viscoelastic mechanical properties. This method can measure repeatedly at various frequencies while the specimen is subjected to very small nondestructive loads. It can also enable us to assess bone material quality as well as bone strength. When utilizing measurement of bone mechanical properties using DMA, researchers need to understand that bone is a viscoelastic material. | |
