[The x-ray semeiotics of spinal involvement in psoriasis].

X-ray examinations of the bone and joint system in psoriasis patients with pain syndromes in the limb joints have revealed spinal involvement in many cases. The authors have distinguished and described x-ray semeiotics of the inflammatory (spondylitis, spondyloarthritis, sacroiliitis), degenerative dystrophic (intervertebral osteochondrosis, spondylarthrosis deformans, spondylosis), and mixed or combined (inflammatory + degenerative dystrophic) involvements of the spine in psoriasis.
