title: Synoviorthesis with erbium-169: a double-blind controlled comparison of erbium-169 with corticosteroid.
abstract: Intra-articular injections of erbium--169 citrate and methylprednisolone acetate in hand joints were compared in a randomly selected double-blind trial. The patients included 21 with rheumatoid arthritis and 3 with psoriatic arthritis, and the design was an intrapatient comparison. No difference between joints treated with the radioisotope or steroid was observed in the year following injection.
