Spondyloarthritis & psoriatic arthritis
Exploring radiographic patterns of the cervical spine, including zygapophyseal joints, in axial spondyloarthritis
Authors' conclusion
Radiographic evaluation of CS is relevant in patients with axSpA and should be assessed routinely. Evaluation of the ZJ is particularly significant, as it is related to higher disease activity and worse function.
Study context
