Is the Site of Back Pain Related to the Location of Magnetic Resonance Imaging Lesions in Patients With Chronic Back Pain? Results From the Spondyloarthritis Caught Early Cohort

ObjectiveTo determine associations between magnetic resonance imaging (MRI) lesions originating from either axial spondyloarthritis (SpA) or from degeneration and pain in patients with chronic back pain of 35 years (OR 5.19; P=0.001), high-intensity zone lesions in females not fulfilling ASAS criteria (OR 5.09; P=0.001), and herniation in various subgroups (OR range 2.07-4.66) were associated with pain. ConclusionSpecific degenerative lesions, but not typical axial SpA lesions, of the spine are associated with pain at the same location in some subgroups. Inflammatory lesions in the SI joint are associated with buttock pain
