Sacroiliac joint injections are minimally invasive procedures used to relieve pain and inflammation in the sacroiliac joint at the base of the spine, which connects the sacrum to the ilium of the pelvis. In order to reduce pain and improve mobility, corticosteroids and local anesthetics are injected directly into the sacroiliac joint. Injections of the sacroiliac joint are commonly used to diagnose and treat conditions such as sacroiliac joint dysfunction, sacroiliitis, and arthritis of the sacroiliac joint.
An assessment of a patient's suitability for a sacroiliac joint injection will typically take place before they undergo a procedure to determine the underlying cause of their symptoms. In addition to a physical examination, a medical history review, and diagnostic tests, such as X-rays, MRIs, and CT scans, this evaluation may include a medical history review. To reduce bleeding risk, patients may be told to discontinue certain medications, particularly blood thinners, in the days leading up to the procedure.
Outpatient sacroiliac joint injections can be performed in a physician's office or a surgery center on an outpatient basis. In order to ensure accurate needle placement in the sacroiliac joint, the procedure is usually performed under fluoroscopic or ultrasound guidance. An anesthetic is administered to numb the area before the injection site is cleaned and sterilized. The doctor will insert a thin needle into the sacroiliac joint under imaging guidance and inject a combination of corticosteroid medication and local anesthetic into the joint space. The entire procedure usually takes less than 30 minutes.
A brief period of time is typically spent in the recovery area after the sacroiliac joint injection to ensure no immediate complications occur. After the procedure, most patients can resume their normal activities, though some may experience mild soreness or discomfort at the injection site for a few days. After receiving the injection, patients should avoid strenuous activities and heavy lifting for a short period of time to allow the medication to take effect.
As with any medical procedure, sacroiliac joint injections carry certain risks and potential complications, even though they are generally considered safe and well-tolerated. Infections at the injection site, bleeding, allergic reactions to the medications used, nerve damage, and temporary discomfort may also occur. Before undergoing sacroiliac joint injections, patients should discuss the potential risks and benefits with their healthcare provider.
Within a few days to weeks of a sacroiliac joint injection, patients may experience pain and inflammation relief. In order to determine the effectiveness of the injection and monitor their progress, patients should keep track of their symptoms and follow up with their healthcare provider on schedule. Occasionally, additional injections may be necessary to provide longer-lasting pain relief. In order to maintain the benefits of the injection and optimize their overall recovery, patients should also follow any prescribed medications or physical therapy exercises.
