Definition

Deforming, non-erosive arthropathy, mainly involving the hands and feet

Classically described in acute rheumatic fever and systemic lupus erythematosus

Clinical features

Progressive, painless deformity of the hands and feet

- metacarpophalangeal (MCP) joints: ulnar deviation
- swan-neck finger deformities, "Z"-shaped thumb
These deformities are reducible by the examiner or the patient

Radiography

Deformities ++

No destructive arthritis

MRI

May be detected:

  • synovitis predominating at the PIP and MCP joints
  • bone erosions well visualized on T1
  • bone marrow edema
  • frequent tenosynovitis (tendon sheath thickening, effusion, and contrast enhancement)

Associated with the previously described deformities (clinical tab)

Management

Possible realignment surgery

Differential diagnosis

Inflammatory arthritis: destructive osteocartilaginous lesions and irreducible deformities
