Treatment of rheumatoid hand synovitis with a regional block technique

This study reports a novel technique for treating painful rheumatoid hand synovitis using a regional block technique. Nine patients with symptomatic rheumatoid hand synovitis were treated. Assessments of symptoms, grip strength and synovial swelling were made in each hand before the injection, and at 1 and 4 weeks after the procedure. A sphygmomanometer cuff was inflated, on the side of the patients most symptomatic hand, to 220mmHg and a solution of hydrocortisone sodium succinate 50mgs and lignocaine 10mls 0.5% was injected intravenously. The cuff was deflated slowly after 20 minutes. The injected hand improved symptomatically in 7 patients at 1 week, and further improvement was reported in 6 of these 7 at 1 month. Mean grip strength increased significantly in the injected hand both at 1 week (p = 0.01) and 1 month (p = 0.018). There was no change in the other hand. This technique is safe, reduced hand pain and improved grip strength in these patients with rheumatoid hand synovitis.
