Rheumatoid Arthritis in One Hand: Monoarticular Presentation and Diagnosis

Yes, RA can present in a single joint (monoarticular), including one hand/wrist, though polyarticular involvement is typical.

Key Features

• Joint pain, swelling, stiffness (>1 hour morning stiffness)
• Warmth, redness over affected joint
• Symmetrical pattern not required for diagnosis

Differential for Monoarticular Hand Arthritis

• Gout/pseudogout (crystals)
• Septic arthritis (emergency)
• Psoriatic arthritis
• Osteoarthritis (DIP/PIP nodes, less inflammation)
• Sarcoidosis, Lyme, reactive arthritis

Diagnostic Workup

• RF, anti-CCP antibodies
• ESR, CRP
• Synovial fluid analysis if tapped
• X-ray/US/MRI for erosions, synovitis

Management

Same principles: early DMARDs (methotrexate), treat-to-target, monitor for progression to polyarticular disease. Hand therapy preserves function.

Any persistent monoarticular arthritis warrants rheumatology evaluation.
