title: [Axial psoriatic arthritis].
abstract: Spinal involvement in PsA is a controversial issue. Currently, in spite of clinical recognition of axial involvement in axial PsA, there is a lack of consensus that impedes elaborating a definition for axial Psa. Recent advances in classification, clinical features, outcome measures and therapeutics are reviewed in this paper.
