Isotope joint therapy

Isotope joint therapy can be used in case of rheumatoid arthritis and rheumatological diseases in which:

  • The synovial membrane that produces synovial fluid proliferates immoderately
  • The overproduction of synovial fluid can be observed and due to this fact drainage of the fluid is necessary from time to time
  • The disease affects only one or some joints.

Therapy should be done in a not so advanced stage of the process, when irreversible articular deformations and injuries have not occurred yet.

The therapy consists of the administration of one intraarticular injection. With this method draining one portion of the synovial fluid is possible and after the administration of the isotope the patient is given antiinflammatory drug (steriod) into the joint. After this the joint has to be moved for a couple of times and then immobility has to be ensured for 48 hours.

The isotope injected into the synovial fluid only takes effect in its direct environment thus destroying the overproductive and immoderately proliferating synovial membrane. This way not only the fluid production is decreased significantly but the formation of articular deformities can also be inhibited.


The isotope joint therapy cannot be used:

  • During pregnancy and breast-feeding
  • In case of infectios joint inflammation
  • In case of a ruptured articular cyst


Side effects

In case of successful administration of the injection significant side effects are not expected. For a couple of days the inflammation of the joint may worsen and the swelling may be increased. Serious side effects can only occur if the administered isotope somehow gets out of the joint. In these cases the tissues (muscles, skin) surrounding the joint may be damaged.
