SI joint injections are used to either diagnose or treat low back pain thought to be due to sacroiliac joint dysfunction. As an essential component of hip pain management, these injections can provide significant relief for patients experiencing SI joint-related discomfort. There are two sacroiliac joints, one on the each side. The joints are below the lumbar spine and connect the sacrum(tailbone) to the pelvis(hips). Two types of Injections can be performed to the SI joint, to either diagnose or treat SI joint pain. These injections are a crucial tool in hip pain management, particularly when conservative treatments have not provided adequate relief. A diagnostic injection will generally only include a numbing medication. A therapeutic injection will contain both a numbing agent and a corticosteroid (cortisone-like anti-inflammatory medication).
You should have your usual pain prior to the facet injection to determine if the injection stops your pain. Do not take any pain medication that day if it will make your pain less. Prior to the procedure, a record of your pain severity and location will be made. Rarely is sedation required.
You will be placed onto a special table for the procedure. After cleansing the skin, a small needle will be directed precisely into the SI joint. Contrast dye is injected to ensure appropriate spread of the medication into the joint. After the contrast dye is injected, the numbing and/or corticosteroid will then be injected. There is generally a brief duration of minimal discomfort during the procedure.
Your skin will be cleansed and a bandage applied as necessary. You will be taken to an observation area and monitored for any adverse reactions, which are very rare. Your usual pain will be re-assessed and documented.
The procedure requires use of x-ray to precisely place the needle. Therefore, if you are pregnant, please inform your physician prior to the procedure. The amount of x-ray exposure is within recommended safe limits for adults, but can be hazardous to the developing fetus.
If you are on blood thinners or anticoagulants, allergies please notify your physician. Special precautions or medication adjustments may be deemed necessary. However, do not stop your medication without consulting with your physician.
Side effects are generally minimal and can include increased discomfort, local bruising, headache, nausea, fainting or dizziness. These symptoms are usually short-lived and will resolve themselves. More severe complications are rare such as infection, allergic reaction, or nerve injury.
