Spondylarthropathies
Spondylarthropathies Definition
Spondylarthropathies are inflammatory joint disorders. The spondylarthropathies include ankylosing spondylitis, Reiter's syndrome, the reactive arthritides, certain subsets of juvenile arthropathy including juvenile ankylosing spondylitis and the seronegative enthesopathic arthropathy syndrome, enteropathic sacroiliitis, psoriatic arthropathy, and possibly a group of rarer disorders such as Behqet's syndrome, Whipple's disease, and pustulotic arthro-osteitis. Different spondylarthropathies can be recognized and differentiated from one another according to the particular peripheral joints concerned, the presentation of clinical features, and the way leading to the progression of the disease.
