As rheumatoid arthritis progresses, pannus formation causes subchondral bone damage and later cartilage and bone destruction. Stretching of ligaments due to capsular distension causes joint instability, and infiltration. These processes are frequently responsible for deterioration in hand function. However, present surgical treatments of wrist and hand deformities allow a degree of independence.
随着类风湿性关节炎的进展，血管翳形成会导致软骨下骨损伤，随后导致软骨和骨破坏。由于关节囊扩张导致的韧带拉伸会引起关节不稳定和浸润。这些过程常常导致手部功能恶化。然而，目前针对手腕和手部畸形的外科治疗能使患者获得一定程度的自理能力。
