[email protected] Abstract: The frequent involvement of the spine and sacroiliac joint has justified the classification of psoriatic arthritis (PsA) in the Spondyloarthritis group. Even if different classification criteria have been developed for PsA and Spondyloarthritis over the years, a well-defined distinction is still difficult. Although the majority of PsA patients present peripheral involvement, the axial involvement needs to be taken into account when considering disease management. Depending on Citation: Giovannini, I.; Zabotti, A.; the definition used, the prevalence of axial disease may vary from 25 to 70% in patients affected by Cicciò, C.; Salgarello, M.; Cereser, L.; De Vita, S.; Tinazzi, I. Axial Psoriatic PsA.
