Radiographic image of the psoriaticarthritis

Overview

Psoriatic arthritis is one of the spondylarthritic diseases with a characteristic radiographic image.On the basis of the published data and considering their own experience with a group of patientstreated at the Institute of Rheumatology, authors describe the main radiographic changes of theperipheral and axial skeleton. Detailed description of pictures illustrates the individual manifestationsof the psoriatic arthritis, namely the changes of hands and foots. Destructive arthritis affectspreferentially distal interfalangeal joints of hands and foots and interfalangeal joints of foot. Othertypical signs an osseous ankylosis of interfalangeal joints of hands and foots, resorption of acralparts of the last phalanges, juxtaarticular periostosis and new formation of bone tissue, osteoperiostitisof the last phalanges. The impairement of the axial skeleton manifests with formation ofsyndesmophytes or para-syndesmophytes, with destructive changes of sacroiliac joints of variousdegrees. The essential characteristics, which differentiate X-ray image of the psoriatic arthritis fromthe rheumatoid arthritis, reactive arthritis, ankylosing spondylitis, diffuse idiopathic skeletalhyperostosis are presented. Paper is accompanied with ample picture documentation.
