Science & evidence
Bone density is not bone quality
The science behind Trabecular Bone Score®: How bone microarchitecture determines fracture risk, and the evidence that's made TBS® the global standard for assessing it.
The core idea
Two bones with the same density can carry very different risk
Bone mineral density measures how much bone is present. But strength also depends on how that bone is built (its microarchitecture). TBS® makes that structural dimension measurable from a routine DXA scan, so patients hiding in a "normal" density are no longer missed.
