TBS adjusted T value

[Nusch]

My DEXA scan was complemented by TBS (Trabecular Bone Score). TBS is a software which measures the bone quality (while DEXA measures the bone density). My T-value for the spine was -3.1, but my TBS adjusted T-value is -2.1. As far as I understand this, my spine has a pretty low bone density but much better bone quality. I have to add that my BMI is only 19.0 and my bones are pretty small. I read, that this could also be a reason for DEXA to come up with a too low bone density

Any experience in this community regarding TBS? Maybe somebody can confirm/correct my assumptions? Much appreciated.

How very interesting, I know nothing but will research.

So I couldn’t find anything on the ROS site but I began with what is Trebecula = a small, often microscopic, tissue element in the form of a small beam, strut or rod that supports or anchors a framework of parts within a body or organ.[1][2] A trabecula generally has a mechanical function, and is usually composed of dense collagenous tissue (such as the trabecula of the spleen). It can be composed of other material such as muscle and bone.

What I understand from that Trebecula is tissue formed into a mesh like structure which is found not only in bone but other organs of the body.

I then found this article which I found informative from the Mayo Clinic

TBS has recently been integrated into international guidelines from the International Osteoporosis Foundation and the International Society for Clinical Densitometry as a validated risk factor for fracture. Further, the FRAX risk assessment tool has recently added a new feature that allows calculated FRAX scores to be adjusted for TBS. As with DXA imaging, TBS can be used at the time of treatment initiation as well as at subsequent visits, and can even be performed retrospectively on archived spine DXA images to assess previous longitudinal changes in lumbar spine bone quality."Finally, it should be noted that at present TBS can only be used to assess bone quality and fracture risk at the spine, although future studies to better understand its clinical utility at the hip appear likely."Related ContentArticleAssessment of bone strength in vivo in humans: A novel diagnostic tool for osteoporosis
