From the Research
For an 83-year-old, a Dual-Energy X-ray Absorptiometry (DEXA) scan is typically recommended every 1-2 years, though this may vary based on individual risk factors and previous scan results. The decision on the frequency of DEXA scans should be tailored to the individual's risk factors and previous scan results, as well as their overall health status and medical history.
Key Considerations
- If the person has normal bone density or mild osteopenia, testing every 2 years may be sufficient 1.
- However, if they have established osteoporosis, significant bone loss on previous scans, or are on medication for osteoporosis, annual scans might be more appropriate to monitor treatment effectiveness 2.
- The frequency may also be adjusted if the individual has risk factors such as recent fractures, corticosteroid use, or certain medical conditions that accelerate bone loss 3, 4.
Monitoring and Treatment
- DEXA scans are valuable at this age because older adults have a higher risk of osteoporosis and fractures, and monitoring bone density helps guide treatment decisions 5.
- The radiation exposure from DEXA scans is minimal, making them safe for repeated use in elderly patients.
- Medicare typically covers DEXA scans every 2 years for qualified individuals, but may approve more frequent scans if medically necessary.
Recent Evidence
- A recent study published in 2022 found that bisphosphonates and monoclonal antibodies can improve bone mineral density in patients following skeletal fractures, highlighting the importance of monitoring and treatment 2.
