What Role Does Trabecular Bone Score Play in Chronic Inflammatory Rheumatic Diseases?

Area of Science:

• Rheumatology
• Radiology
• Osteoporosis Research

Background:

• Rheumatic inflammatory diseases like rheumatoid arthritis increase fracture risk due to low bone mass.
• Dual-energy X-ray Absorptiometry (DXA) measures bone mineral density (BMD), but offers limited microarchitecture insights.

Purpose of the Study:

• To review the clinical literature on osteoporosis in rheumatic diseases.
• To highlight the role of Trabecular Bone Score (TBS) in evaluating bone health and fracture risk.

Main Methods:

• Review of scientific literature on osteoporosis and TBS in chronic inflammatory rheumatic diseases.
• Analysis of TBS's ability to characterize trabecular bone microarchitecture from lumbar spine DXA images.

Main Results:

• Low TBS values correlate with an increased incidence of fractures in rheumatic disease patients.
• TBS enhances skeletal information beyond standard BMD measurements.

Conclusions:

• Combining BMD and TBS provides valuable insights for assessing bone damage.
• TBS is a promising tool for identifying individuals at higher risk of fractures in rheumatic inflammatory conditions.
