The book was originally commissioned due to the recent advances in the field and is an update to the 2009 Clinician s Manual on Ankylosing Spondylitis. The Manual is heavily illustrated with demonstrative images, diagnostic guides and treatment algorithms from the authors practice and from their organization the ASAS (Assessment in SpondyloArthritis international Society).
