Following the injection, the patient usually remains for 30 minutes to ensure that there are no immediate complications or adverse reactions, such as allergic reaction or leg weakness / numbness. The doctor or other team member will determine when it is safe for the patient to go home.
Following a diagnostic or combination diagnostic / therapeutic sacroiliac joint injection, the patient's pain level is assessed by having the patient perform activities that would usually provoke pain. The percentage of pain relief is documented and a physical examination is performed. A positive response is defined as at least 75 percent improvement of the patient's painful activity related symptoms. If a second diagnostic injection is positive, then the sacroiliac joint is considered the likely source of the patient's painful symptoms.
Although individual recommendations may differ, depending on the patient’s situation and the physician’s preference, the following are typical:
- Drink plenty of water to help flush the dye used for fluoroscopy out of the body.
- Do not perform excessive activities on the day of the procedure, especially if sedation was administered.
- A list of signs or symptoms that warrant immediate medical attention will often be provided to the patient as a part of the discharge procedure.
Possible Risks of Sacroiliac Joint Injection
Risks related to this procedure tend to be relatively minor and occur infrequently. Typical risks include:
- Risks related to the medications used in the injection, such as a possible allergic reaction to a medication.
- Bruising and/or soreness at the injection site.
- Infection at the injection site, deeper tissues, or in the joint.
Following an SI joint injection, your physician might ask you to participate in a specific treatment program. This might include a pelvic stabilization program with physical therapy and/or manipulation therapy under the supervision of an osteopathic physician, physical therapist, or a chiropractor.
