Spondyloarthropathy (SpA) can be difficult to diagnose, with rheumatologists sometimes relying on classification criteria designed for clinical trials. Research examines how the use of MRIs affects the finding of bone marrow edema and the diagnosis of axial SpA.
Spondyloarthropathy is an ancient form of arthritis shared by multiple orders and classes of the animal kingdom. Camarasaurus, a genus of quadrupedal, herbivorous dinosaur, holds the record for the earliest known case of spondyloarthropathy—147 million years ago.
The differences between axial spondyloarthropathy (axSpA) and axial involvement in psoriatic arthritis (axPsA) have clinical and therapeutic implications. Three experts discussed the distinctions during ACR Convergence 2021.
