Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disorder characterized by inflammation of the synovial joints. In the hand, RA often leads to joint destruction, deformity, and functional impairment. This blog explores RA’s pathophysiology, clinical signs, diagnostic markers, and modern treatment approaches, emphasizing hand-specific considerations and surgical options.
RA in the hand begins with an autoimmune attack on the synovium, resulting in chronic inflammation. Over time, this leads to:
Synovial hyperplasia and pannus formation that erodes cartilage and bone.
Cytokine involvement (TNF-α, IL-1, IL-6) driving inflammation and osteoclastic activation.
Ligament laxity, tendon rupture, and joint instability, leading to characteristic deformities like ulnar drift, swan-neck, and boutonnière deformities.
Medical Management
Hand-Specific Treatment
Outcomes & Considerations
Biologic therapies have improved systemic control, but hand deformities still necessitate surgical intervention. A multidisciplinary approach, combining rheumatology, hand surgery, and rehabilitation, is crucial for optimizing patient outcomes.
Conclusion
RA in the hand is a progressive autoimmune disorder requiring early and comprehensive management. Early systemic treatment with DMARDs and biologics, alongside hand-specific therapies, can improve long-term function and quality of life. For advanced cases, surgical correction remains essential to restoring hand function.
