Osteoporosis: why bone density is not the only important indicator for seniors

Why bone density doesn't tell the whole story about fracture risk

Many older adults know that osteoporosis means brittle bones, and doctors often recommend measuring bone density to assess fracture risk. However, specialists warn that this indicator alone does not provide a complete picture of bone health. The quality of the bone's internal structure plays an equally important role — if not more so — in determining its fragility.

The internal structure of bone – a frequently overlooked factor

Bone is not a solid, uniform mass. It has a complex architecture, made up of networks of fine bony trabeculae that give it strength. When this internal structure deteriorates — even if bone density remains at acceptable levels — the risk of fracture increases significantly. This is precisely why assessments based solely on bone densitometry (DXA) may underestimate the true risk for some elderly patients.

Osteoporosis and fractures – a major concern for older adults

Fractures caused by osteoporosis are among the most common and serious complications in elderly people. Hip fractures in particular are associated with a dramatic loss of mobility and independence, as well as an increased risk of death within the first year following the injury. Preventing these fractures should be a priority for older adults, as well as for their families and carers.

Comprehensive assessment – when further investigations are needed

Doctors recommend that, in certain cases, the assessment of osteoporosis should be supplemented with investigations that provide information about the structural quality of the bone, not merely its mineral content. These methods can identify patients at high risk of fracture even when bone density shows no obvious problem. The decision regarding which investigations are needed rests with the specialist, who takes into account the patient's age, medical history, and other individual risk factors.

Recommendations for older adults and their families

• Speak with your GP or rheumatologist about a comprehensive assessment of bone health, particularly after the age of 65
• Do not ignore symptoms such as back pain, loss of height, or a stooped posture — these may be signs of bone deterioration
• An active lifestyle, a diet rich in calcium and vitamin D, and avoiding smoking all contribute to maintaining bone health
• Assess the risk of falls in the home and adapt the environment to prevent accidents

The prevention and accurate diagnosis of osteoporosis remain essential for maintaining quality of life in older age. A thorough and comprehensive assessment can make the difference between an independent life and one marked by fractures and immobility.
