Erosive Arthropathies

The primary erosive arthropathies to consider are rheumatoid arthritis (RA), psoriatic arthritis, erosive osteoarthritis, gout, and calcium pyrophosphate deposition disease (CPPD). 1

Major Erosive Arthropathies

Classic Inflammatory Arthropathies

  • Rheumatoid Arthritis: The prototypical erosive arthropathy, characterized by non-proliferative marginal erosions with high specificity 1. Primarily targets MCPJs, PIPJs, and wrists 1

  • Psoriatic Arthritis: May target DIPJs or affect just one ray in a distinctive pattern 1. Erosions tend to occur at the "bare areas" of joints, with linear periosteal bone apposition being common 2

  • Gout: Can superimpose on pre-existing osteoarthritis 1. Urate crystals provide definitive diagnosis with high specificity 1

Erosive Osteoarthritis (EOA)

Erosive osteoarthritis is a specific aggressive subset of hand osteoarthritis that selectively targets interphalangeal joints with subchondral erosions, bony collapse, and potential ankylosis 1. This condition demonstrates:

  • Worse clinical and structural outcomes compared to non-erosive OA 1
  • Abrupt onset with marked pain and functional impairment 1
  • Inflammatory features including soft tissue swelling, erythema, and mildly elevated CRP 1
  • Radiographic features of subchondral erosion progressing to marked bone and cartilage attrition 1

Crystal-Induced Arthropathies

  • Calcium Pyrophosphate Deposition Disease (CPPD): Radiographic changes are extremely similar to hand osteoarthritis and may coexist with it 1. The erosive changes can be identical in character to erosive osteoarthritis 3

  • Haemochromatosis: Mainly targets MCPJs and wrists 1

Less Common Erosive Arthropathies

Connective Tissue Disease-Associated

  • Systemic Lupus Erythematosus (SLE): Up to 40% of SLE patients with joint involvement can develop erosive damage using sensitive imaging 4. Erosive arthritis in SLE occurs in 1.5% of patients and is strongly associated with anti-CCP antibodies (80% positive in erosive cases) 5, 6

  • Sjögren Syndrome: Erosive arthritis noted in 5.8% of patients with primary Sjögren syndrome 6

  • Systemic Sclerosis: Erosive arthritis occurs in 9.1% of patients 6

Key Diagnostic Distinctions

A composite of multiple features is essential for accurate diagnosis rather than relying on single criteria 1. Critical distinguishing features include:

  • Joint distribution pattern: RA favors MCPJs/PIPJs/wrists; psoriatic arthritis may affect single rays or DIPJs; erosive OA selectively targets IP joints 1

  • Erosion characteristics: RA shows sharply defined marginal erosions; erosive OA demonstrates subchondral erosions with a "smudged" or crumbling appearance 3, 2

  • Laboratory markers: Strongly positive RF supports RA; elevated urate supports gout; anti-CCP antibodies are associated with erosive disease in both RA and connective tissue diseases 1, 5, 6

Important Clinical Pitfalls

The term "erosive osteoarthritis" itself is controversial, as some evidence suggests these erosive changes may actually represent complicating CPPD rather than true OA 3. The radiographic appearance and unique responsiveness to hydroxychloroquine treatment support this alternative interpretation.

Additionally, traditional concepts of "non-erosive" arthritis in conditions like SLE have been challenged by modern imaging techniques (ultrasound, MRI), revealing erosive damage in a substantial proportion of patients previously classified as non-erosive 4.
