From the Research
Jaccoud's arthropathy is characterized by reversible joint deformities, including ulnar deviation, swan neck, and "z" thumb deformities, with no bone erosion visible on plain radiographs, but small bone erosions may be detectable using more sensitive imaging methods such as magnetic resonance imaging or high-performance ultrasound, as reported in the most recent study 1. The characteristic images of Jaccoud's arthropathy typically include:
- Ulnar deviation of the fingers
- Swan neck deformities
- "Z" thumb deformities
- No bone erosion on plain radiographs, but possible small bone erosions on more sensitive imaging methods It is essential to note that Jaccoud's arthropathy is a condition that primarily affects patients with systemic lupus erythematosus (SLE) or other inflammatory conditions, and its prevalence is approximately 5% in SLE patients 1. To view images of Jaccoud's arthropathy, I would recommend consulting medical textbooks, journals, or reputable medical websites that specialize in rheumatology, or discussing with a rheumatologist who might have access to clinical photographs for educational purposes. Some studies have suggested that Jaccoud's arthropathy may not be entirely non-erosive, as bone erosions can occur in some patients, particularly those with anti-citrullinated protein antibodies (ACPA) positivity 2. However, the most recent and highest-quality study 1 provides the most accurate and up-to-date information on the characteristic images of Jaccoud's arthropathy.
