FERNANDEZ MORALES, Alejandro et al. Usefulness of Trabecular Bone Score in combination with bone densitometry to assess a series of 194 patients. Rev. Méd. Urug. [online]. 2022, vol.38, n.1, e204.  Epub Mar 01, 2022. ISSN 0303-3295.


most fractures that result from bone fragility occur in the osteopenia range The trabecular bone score (TBS) enables the assessment of microarchitecture aspects that impact bone resistance.


to describe the clinical characteristics and findings of bone microarchitecture, by applying TBS and bone densitometry in a group of patients.


descriptive study of retrospective collection. Patients who were included in the study underwent a Dual-energy X-ray Absorptiometry (DXA) with TBS at the National Rheumatology Service between July and August, 2020.


94 patients were analysed, 173 (89%) were female and 21 (11%) were male. 36.1% (70 patients) lay in the osteopenia range, 36.1 (70 patients) in the osteoporotic range. 32.9% (23 patients) with osteopenia and 47.1% (33 patients) with osteoporosis evidenced a degraded bone microarchitecture.

76.9 % of patients with rheumatoid arthritis and 45.8 % of patients with spondyloarthritis respectively evidenced altered bone microarchitecture.


TBS allowed stratification of fracture risk in a significant number of patients, which may suggest it is a useful tool for complementary assessment of bone health.
