[Intra-articular injection of radioactive yttrium 90 in the hemophilic arthropathies. About nine cases (author's transl)].

The authors report 9 cases of intra-articular injection of radioactive yttrium 90. They specify the very place of this therapeutics in the hemophilic arthropathies treatment. Y 90 seems to give better results than osmic acid but cannot be used before the full growth. Thereby the authors point out the respective directions of their use.
