Today we present 3rd part of information about the Trabecular Bone Score (TBS) value in fracture prediction in Rheumatology in Spondyloarthritis (SpA).

Patients with spondyloarthritis (SpA) are at increased risk of pathological vertebral fracture. These patients usually present syndesmophytes, a bony growth inside the ligament, which often results in overestimation of the BMD measurements leading to misdiagnosis.

Individuals with axial SpA and fractures had lower TBS scores and the disease activity was associated with low TBS values. TBS is not influenced by the syndesmophytes therefore it can help to assess bone quality in this population.

Selected publications related to Trabecular Bone Score (TBS) in Spondyloarthritis (SpA):

  • Wildberger, L. et al. Impact of lumbar syndesmophyte on bone health as assessed by bone density (BMD) and bone texture (TBS) in men with axial spondyloarthritis. Joint Bone Spine 84, 463–466 (2017).
  • Boussoualim, K. et al. Evaluation of bone quality with trabecular bone score in active spondyloarthritis. Joint Bone Spine (2018) doi:10.1016/j.jbspin.2018.02.006.
