Trabecular Bone Score
The measure of bone quality, not just quantity
Bones do more than hold us up, and their strength depends on more than density alone. Here's what that means for you.
Osteoporosis if often silent
Many people don't know they have it until a bone breaks
Why it matters
Strong bones, a fuller life
Your bones give your body structure, protect your organs, and let you move. As we age — or because of certain medical conditions — bones can change in ways that make them more likely to break.
Osteoporosis is a condition where bones become fragile and more likely to break, sometimes from a minor fall or even everyday movements like bending or coughing. It's often called a "silent" disease because there are usually no symptoms until a bone breaks. Understanding and looking after your bone health helps prevent fractures and keeps you mobile and independent.

Beyond bone density
See the quality of your bones, not just the amount
A bone density (DXA) scan measures how much mineral is in your bones. But two people with the same bone density can have very different bone quality (how well the bone is built inside.) That internal structure matters for how strong your bones really are.
Trabecular Bone Score® (TBS®) works alongside your bone density test, using the same scan — with no additional radiation, or time — to give your doctor extra information about the quality of your bones and personalise your care.
BMD alone can't identify bone quality
Bone density can appear normal, even while the structure is weak
TBS® is available at imaging centres and clinics in 90+ countries. Ask your doctor whether TBS® can be added to your bone density scan.
