Ankylosing Spondylitis (AS) is a chronic inflammatory systemic disease belonging to the SpondyloArthritidies with axial joint involvement and enthesitis, with or without peripheral arthritis and systemic involvement. We know that the clinical/paraclinical judgement of an expert Rheumatologist is the gold standard for diagnosis of AS. It is mentioned that the 1984 modified New York criteria is applied for classification of AS and it is not a good instrument for early detection of disease. The author by this letter delivers a new criteria called 2016 New York revised criteria that is applied for too early diagnosis of AS. With the addition of pelvic MRI, HLA-B27 positivity, positive family history of AS, Enthesitis/arthritis and positive sacral push test to the 1984 modified New York criteria and deletion of limited chest expansion from it, this new criteria has been created.
