Abstract

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: 194 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.
