Abstract
In five patients under the age of 15 with hemophilia and inhibitors, due to frequent joint bleedings, 13 joints were treated with synoviorthesis (intra-articular injection of radioactive gold). The patients received high doses of factor VIH/IX for 2-4 days or were treated simultaneously with tolerance induction according to the Malmö protocol. Of the 13 joints treated, a bleeding-free interval of more than 6 months was obtained in nine of which six remained free from bleedings for more than a year. Ease of performance, the limited requirements of pre- and postoperative care, and a definite decrease in the joint bleeding frequency render synoviorthesis well suited for use in hemophiliacs with inhibitors who are otherwise difficult to treat.
