Abstract

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.  https://doi.org/10.29193/rmu.38.1.4.

Introduction:

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.

Objective:

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

Method:

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.

Results:

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.

Conclusions:

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.
