Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Jaccoud arthropathy

Jaccoud arthropathy is a non-erosive deforming arthropathy seen in lupus and rheumatic fever. The deformities are due to ligament and capsule laxity and are initially reducible. The absence of erosions on radiographs distinguishes it from rheumatoid arthritis.

Option by option

  • A. Rheumatoid arthritis with erosions

    Rheumatoid arthritis causes erosions, and the deformities become fixed.

  • B. Psoriatic arthritis mutilans

    Psoriatic arthritis mutilans causes severe bone destruction with telescoping digits.

  • C. Jaccoud arthropathy (correct)

    Correct. A reducible, non-erosive deforming arthropathy in lupus is Jaccoud arthropathy.

  • D. Nodal osteoarthritis

    Nodal osteoarthritis causes Heberden and Bouchard nodes rather than ulnar deviation.
