title: The relevance of large-vessel vascular disease and restricted ankle movement to the aetiology of leg ulceration in rheumatoid arthritis.
abstract: Leg ulceration in rheumatoid arthritis (RA) without systemic vasculitis is a difficult clinical problem and a common cause of morbidity. We have assessed venous function, arterial pressures and range of ankle movement in 23 RA patients with a leg ulcer and compared the results with those in the non-ulcerated contralateral limb and in 25 RA patients matched for age and duration of arthritis. We found evidence of venous insufficiency in RA ulcer patients compared to disease controls. Ankle movement was more restricted in the ulcerated limb compared to the non-ulcerated contralateral leg. There was no difference in large-vessel arterial function between groups. These findings have implications for therapy and rates of healing.
