Strong joints

Joint stiffness is a typical symptom of spondylotic spondylitis of the joint. Juvenile ankylosing spondylitis (JAS) refers to connective tissue disease characterized by chronic inflammation of the joints such as the sacroiliac and spine before the age of 16. It is a typical spondyloarthropathy, with a peak incidence in young and middle-aged people, but some cases often develop in a latent form in childhood. Therefore, juvenile arthrosclerotic spondylitis (JAS) is often misdiagnosed as juvenile rheumatoid joint Inflammation (JRA). Lower extremity major arthritis is often misdiagnosed as JRA oligoarthritis type II. Typical JAS will gradually show pain in the waist, buttocks, and palate, and inflammation of the tendon attachment site will detect sacroiliitis earlier. JAS is predominantly older. Given the considerable number of JAS patients with peripheral joint disease, it is often referred to as spinal joint disease syndrome.
