[Arthropathy of sacro-iliac joints in psoriasis (author's transl)].

Roentgenographic studies of the sacroiliac joints were carried out in 117 psoriatic patients with associated symptoms of joint and/or bone involvement and in eleven psoriatic patients without signs of bone or joint disease. In all patients arthritis of the sacro-iliac joints with varying degree of severity was demonstrated. The sacro-iliac joint space remained open in patients without associated rheumatoid arthritis or ankylosing spondylarthritis. It was shown that the described method in the assessment of the sacro-iliac joints is fully justified.
