Abstract
Radiosynovectomy is a local form of radiotherapy used as second-line treatment in the management of inflammatory and non-inflammatory arthropathies with unsatisfactory response to local or systemic corticos - teroid therapy. Its efficacy is similar to that of surgical synovectomy, with the advantages of being a low-cost and minimally- invasive treatment that requires a shorter recovery time. Its efficacy is greater in the treatment of inflammatory arthritis characterized by synovitis, such as rheumatoid arthritis and juvenile chronic arthritis with mono/ oligoarticular involvement, especially in upper extremity joints. A number of isotopes can be used in colloidal suspensions. Rhenium-186-sulphide colloid is currently indicated for the treatment of medium-sized joints. The ultrasound-guided injection is suitable for small joints, such as wrist. For proper and safe use and administration of this technique the collaboration of a trained and experienced radiologist is critical to successful treatment.
