[Early diagnosis of spondylarthritis ankylopoietica]

For the early recognition of the ankylopoietic spondylarthritis subjective and objective criteria are explained and the importance of X-ray-morphological, cytological, biochemical, immunogenetic and coagulation-physiological investigations are explained. By accentuation of two types of constellation of the course the possibility of an early diagnosis is given still before the appearance of severe irreparable X-ray-morphological changes in about half the cases of disease. Further observations and controls of courses are necessary for the confirmation of evidence.
