Abstract
Abstract 166 Holmium in a carrier metallic hydroxide aggregate is disclosed for the treatment of arthritis and, in particular, rheumatoid arthritis. The compound disclosed preferably has a particle size of 1 to 40 microns, Beta energy emissions in the range of 1.76-1.84 MeV, low levels of gamma ray emissions and a radioactive half-life of 26.8 hours. The preferred metallic hydroxide is selected from the group consisting of Ferric Hydroxide, Aluminum Hydroxide, Bismuth Hydroxide, Chromium Hydroxide, Cupric Hydroxide, Manganese Hydroxide and Stannous Hydroxide. Methods are also disclosed for the preparation of the compound, as well as for the methods of its administration to a patient in need thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
57 words
A method for the treatment of arthritis comprising administering an effective amount of a radioactive composition including an aggregated suspension having particles, the particles having a minimum particle size of one micron, the aggregated suspension including particles containing 166 Holmium, to the inflamed synovium of the particular joint of a mammal body in need of such treatment.
Claim 2
Independent Claim
57 words
A method for the treatment of arthritis comprising administering an effective amount of a radioactive composition including an aggregated suspension having particles, the particles having a minimum particle size of one micron, the aggregated suspension including particles containing 166 Holmium, to the inflamed synovium of the particular joint of a mammal body in need of such treatment.
Claim 3
Independent Claim
152 words
A method for the treatment of arthritis of an articular joint including skin, subcutaneous tissue and a joint space, said method comprising the steps of: preparing an aggregated suspension containing particles, the particles having a minimum particle size of one micron, the aggregated suspension including particles containing 166 Holmium; preparing a solution of one percent lidocaine hydrochloride; placing the aggregated suspension in a needle assembly having a 19 gauge needle including a needle tract and a three-way stopcock; washing the skin of the articular joint with a bentadient solution; instilling the lidocaine hydrochloride in the skin and subcutaneous tissue; injecting the aggregated suspension into the joint space in a standard lateral approach; cleansing the needle and needle tract by flushing with one percent lidocaine hydrochloride through the stopcock assembly as the needle is withdrawn; moving the joint through a flexion-extension arc; and immobilizing the joint in full extension for approximately 24 hours.
Claim 4
Independent Claim
152 words
A method for the treatment of arthritis of an articular joint including skin, subcutaneous tissue and a joint space, said method comprising the steps of: preparing an aggregated suspension containing particles, the particles having a minimum particle size of one micron, the aggregated suspension including particles containing 166 Holmium; preparing a solution of one percent lidocaine hydrochloride; placing the aggregated suspension in a needle assembly having a 19 gauge needle including a needle tract and a three-way stopcock; washing the skin of the articular joint with a bentadient solution; instilling the lidocaine hydrochloride in the skin and subcutaneous tissue; injecting the aggregated suspension into the joint space in a standard lateral approach; cleansing the needle and needle tract by flushing with one percent lidocaine hydrochloride through the stopcock assembly as the needle is withdrawn; moving the joint through a flexion-extension arc; and immobilizing the joint in full extension for approximately 24 hours.
Claim 5
Independent Claim
44 words
A method for the treatment of arthritis of an articular joint comprising: administering a therapeutically effective quantity of an aggregated suspension containing particles, the particles having a minimum particle size of minimum, the aggregated suspension including particles containing 166 Holmium to perform radiation synovectomy.
Claim 6
Independent Claim
