    Features are
    1. soft tissue swelling: this can be an early/only radiographic finding
    2. osteoporosis: that is initially juxta-articular, and later generalised. It is compounded by corticosteroid therapy and disuse
    3. joint space narrowing: symmetrical or concentric
    4. marginal erosions

    Late changes include :

    5. subchondral cyst formation(Geode): destruction of cartilage presses synovial fluid into the bone
    6. subluxation causing:ulnar deviation of the MCP joints, boutonierre and swan neck deformities
    7. hitchhiker’s thumb deformity
