Comparison of Diagnostic and Therapeutic Efficacy of Periarticular And/or Intraarticular Lidocaine Injections Under Ultrasound Guidance in Sacroiliac Joint Dysfunction

"The procedure involves the administration of a 2.5 cc injection of 2% lidocaine to the sacroiliac joint, targeting the articular or periarticular areas. The injection is performed under real-time ultrasound guidance to ensure accurate placement of the needle.~The 2% lidocaine solution is injected into both the joint space (articular area) and the surrounding soft tissues (periarticular area), which may include ligaments, capsules, and adjacent muscles. The goal is to temporarily anesthetize the joint and surrounding structures to assess the contribution of the sacroiliac joint in the patient's pain, as well as to provide therapeutic pain relief. The use of ultrasound ensures minimal risk of injury to surrounding structures and enhances the accuracy of the injection.~This intervention is commonly used in both diagnostic and therapeutic settings, helping to confirm the role of the sacroiliac joint in a patient's symptoms and providing relief in cases of sacroiliac joint dysfunction."
