  2. Stages of Rheumatoid Arthritis Stage I:    - represents synovitis:    - synovial membrane becomes hyperemic and edematous with foci          of infiltrating small lymphocytes;    - joint effussions w/ high cell count (5,000 to 60,000 per mm3)    - x-rays will as yet show no destructive changes, but soft tissue          swelling or Osteoporosis may be seen;- Stage II:    - inflammed synovial tissue now proliferates & begins to grow into joint          cavity across articular cartilage, which it gradually destroys;    -narrowing of joint due to loss of articular cartilage;- Stage III:    - pannus of synovium    - eroded articular cartilage & exposed sub-chondral bone;    - x-rays will show extensive cartilage loss, erosions around the margins          of joint, and deformities may have become apparent;- Stage IV:    - end stage disease;    - inflammatory process is subsiding;    - fibrous or bony ankylosing of joint will end its functional life;    - subcutaneous nodules associated w/ severe disease; Wheeless' Textbook of Orthopaedics http://www.wheelessonline.com/ortho/stages_of_rheumatoid_arthritis
