Sacroiliac Joint Injections are intended to either treat or diagnose lower back pain associated with sacroiliac joint dysfunction or arthritis in the sacroiliac joint. The sacroiliac joint is the place where the sacrum and the iliac bones connect. It is where the tailbone and the pelvis are joined by very strong ligaments. A steroid medication and anesthetics mix is used for the injection to help reduce swelling and inflammation in the joint as well as help relieve pain.
During sacroiliac joint injections, the patient lies down on his/her stomach. A local anesthetic is used to numb the skin and the tissue down to the sacroiliac joint. The physician will use touch and a fluoroscope to find the sacroiliac joint and then, gently advancing the needle to the joint, inject the medicine. The needle is then removed and a small bandage is applied. The patient will remain in the surgery center for at least 30 minutes for observation after the procedure. If there are no adverse reactions (allergic reaction or leg numbness/weakness), the doctor will release the patient to go home.
This injection procedure is performed to relieve pain caused by arthritis in the sacroiliac joint where the spine and hip bone meet. The steroid medication can reduce swelling and inflammation in the joint.
