Which statement about calcaneal ultrasonometry is TRUE?

Calcaneal ultrasonometry is a non-invasive method used to assess bone density, particularly in the calcaneus or heel bone. The technique utilizes ultrasound waves to measure the properties of bone, which can provide an indirect evaluation of bone density. This is significant since assessing bone density is crucial for identifying individuals at risk for osteoporosis and fractures, especially in older adults.

The method is relatively accessible and does not necessitate high-tech equipment, contrary to what might be implied by requiring high technology equipment. Moreover, while it offers valuable insights into bone health, it is generally considered reliable for assessing the status of bone density in older adults, which counters the assertion of unreliability.

Therefore, the statement that calcaneal ultrasonometry measures bone density indirectly reflects its primary function in clinical orthopedic and geriatric practice. This use of ultrasound makes it a useful tool in monitoring bone health without the need for more invasive or expensive procedures.
