What does the Stiffness Index combine to assess bone health?

• A. Bone Mineral Density and Ultrasound Velocity
• B. Bone Ultrasound Attenuation and Speed of Sound
• C. Bone Mineral Density and Protein Content
• D. Bone Ultrasound Attenuation and Chemical Composition

Answer: (B)

The Stiffness Index is a measure used in assessing bone health that combines Bone Ultrasound Attenuation (BUA) and Speed of Sound (SOS). This combination is particularly relevant in the context of assessing the mechanical properties of bone, as both BUA and SOS provide insights into the density and structure of bone. Bone Ultrasound Attenuation refers to how much the ultrasound waves are absorbed or scattered as they travel through the bone. Higher values of BUA typically indicate denser, healthier bone. On the other hand, Speed of Sound measures how quickly the ultrasound wave travels through the bone, which is influenced by both the density and the elastic properties of the bone material. Together, these factors give a comprehensive picture of bone integrity and the potential for fracture risk. This dual approach allows for a non-invasive means of evaluating bone quality, which is essential in diagnosing conditions such as osteoporosis and in monitoring treatment effectiveness. Thus, the correct choice effectively captures the essence of how the Stiffness Index evaluates bone health by relying on parameters that reflect bone structure and mechanical integrity.
