This review discusses two medical books: "Ankylosing Spondylitis" by J. Forestier, F. Jacqueline, and J. Rotes-Querol, and "Rhumatologie Clinique" by Pierre P. Ravault and Georges Vignon. The first book emphasizes the distinction between ankylosing spondylitis and rheumatoid arthritis, highlighting early symptoms such as sacro-iliac pain and the importance of clinical examination. It provides detailed descriptions of diagnostic challenges, including the absence of mention of certain conditions like crippling fluorosis and sacro-iliac joint changes in traumatic paraplegia. The book also discusses laboratory tests, x-ray findings, and treatment options, including the use of gold and cortisone. However, it lacks information on the risks of combining certain drugs and omits some important diagnostic techniques. The second book, "Rhumatologie Clinique," is a practical guide to rheumatology, covering major diseases like osteoarthritis and ankylosing spondylitis. It includes high-quality illustrations and detailed interpretations, making it easy to read. However, it has some shortcomings in the treatment of minor conditions, such as the lack of discussion on surgical options for "trigger" finger. Both books are valuable resources for those interested in rheumatic diseases.This review discusses two medical books: "Ankylosing Spondylitis" by J. Forestier, F. Jacqueline, and J.
