Abstract
The present invention provides radiation synovectomy compositions for treating inflamed synovium containing a radionuclide complex bound to a hydroxyapatite-like matrix as the radiolabelled synovectomy agent in a sufficient amount to provide satisfactory synovectomy of the inflamed synovium together with a pharmaceutically acceptable vehicle, the radionuclide being a beta emitter that will substantially ablate the inflamed synovium, but not significantly damage underlying articular cartilage, the radionuclide complex being substantially kinetically stable, and if said radionuclide or radionuclide complex leaks from said joint it will be excreted from the body, the agent having a particle size such that there is essentially little or no leakage of the radionuclide complex from the joint after administration.
