In plain words

What the trial is, and whether it could suit you

Radiographic axial spondyloarthritis (r-axSpA) causes progressive structural damage of the spine, conventionally quantified on lateral cervical and lumbar radiographs using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Repeated radiography entails cumulative radiation exposure, substantial inter-reader variability and low sensitivity in early disease. DIERS Formetric 4D surface topography provides radiation-free three-dimensional modelling of the spine and pelvis. The association between sagittal balance and structural damage has been demonstrated with a radiation-based system (EOS), but whether a radiation-free topographic method reflects the same association has not been investigated. This single-centre, cross-sectional observational study will enrol 53 adults with r-axSpA fulfilling the ASAS criteria with radiographic sacroiliitis according to the modified New York
