What condition is primarily monitored using bone density studies?

• A. Osteosarcoma
• B. Paget’s disease
• C. Osteoporosis
• D. Rickets

Answer: (C)

Bone density studies are primarily used to monitor osteoporosis, which is a condition characterized by decreased bone mass and deterioration of bone tissue, leading to an increased risk of fractures. This condition is particularly prevalent among older adults, especially postmenopausal women, due to hormonal changes that affect bone density.

The main purpose of bone densitometry is to assess bone mineral density (BMD), which helps in diagnosing osteoporosis, predicting the risk of fractures, and determining the effectiveness of treatments over time. The results can guide clinicians in making decisions about preventative strategies and therapeutic interventions for patients at risk of bone loss.

In comparison, conditions like osteosarcoma are cancers that affect the bones, but they do not primarily utilize bone density studies for monitoring. Paget’s disease involves abnormal bone remodeling but is usually not the main focus of bone density scans. Rickets, a childhood disorder resulting from vitamin D deficiency, affects bone development but again is not primarily monitored through routine bone density assessments. Thus, osteoporosis stands out as the condition directly linked with the purpose of bone densitometry.
