Introduction: Radiosynovectomy (RSV) is a minimally invasive procedure used to treat joint inflammation and pain caused by various inflammatory joint diseases, such as rheumatoid arthritis and homophilic arthropathy. It involves the injection of a radioactive substance into the affected joint, which selectively targets and destroys inflamed synovial tissue. In this article, we will explore the principles, procedure, indications, benefits, and potential side effects of radiosynovectomy.

Principles of Radiosynovectomy: The primary objective of radiosynovectomy is to reduce joint inflammation and alleviate pain. It utilizes a radioactive isotope, typically yttrium-90 (Y-90) or rhenium-186 (Re-186), which emits beta radiation. When injected into the joint, the radiopharmaceutical particles selectively target the hyperplastic synovial tissue, causing irradiation and subsequent destruction of the inflamed synovium.

Indications for Radiosynovectomy: Radiosynovectomy is primarily indicated for patients with persistent joint inflammation and pain despite optimal medical management. It is commonly used in the following conditions:

  1. Rheumatoid Arthritis: Radiosynovectomy can provide relief in cases of persistent synovitis and pain in rheumatoid arthritis patients.
  2. Hemophilic Arthropathy: Patients with hemophilia who develop recurrent joint bleeds and chronic synovitis can benefit from radiosynovectomy.
  3. Other Inflammatory Joint Diseases: Radiosynovectomy may be considered in certain cases of seronegative spondyloarthropathies, psoriatic arthritis, and other inflammatory joint disorders.

Benefits of Radiosynovectomy: Radiosynovectomy offers several advantages as a therapeutic approach for joint inflammation

  1. Localized Treatment: Radiosynovectomy provides targeted treatment directly to the inflamed synovium, minimizing systemic side effects.
  2. Non-Surgical Approach: As a minimally invasive procedure, radiosynovectomy avoids the need for open joint surgery and associated risks.
  3. Outpatient Procedure: Radiosynovectomy is typically performed as an outpatient procedure, allowing for quick recovery and minimal disruption to daily activities.
  4. Cost-Effective: Compared to other treatment options, radiosynovectomy can be a cost-effective solution for managing chronic joint inflammation.

Radiosynovectomy is a valuable therapeutic option for patients with persistent joint inflammation and pain caused by various inflammatory joint diseases. This minimally invasive procedure offers localized treatment, avoids the need for open surgery, and has shown to be effective in reducing joint inflammation and improving symptoms. While potential side effects and complications exist, they are typically manageable and outweighed by the benefits of this procedure. Radiosynovectomy, in conjunction with comprehensive medical management, can significantly enhance the quality of life for patients suffering from chronic joint inflammation.
