Juxta-articular erosions in reflex sympathetic dystrophy.

Thirty-one patients with documented reflex sympathetic dystrophy syndrome (RSDS) were reviewed for their radiographic changes. Juxta-articular and metaphyseal bone loss was found in the majority of the patients. Juxta-articular bone loss closely resembling erosions seen in rheumatoid arthritis was found in all the patients. The significance of these findings is discussed.
