Sacroiliac Joint Injection
WHAT IS SACROILIAC JOINT INJECTION?
The sacroiliac joint (SIJ) is a non-moving joint between the sacrum and ilium bone, known for its high friction. To diagnose and treat inflammation causing pain in the lower back, buttocks, abdomen, groyne, or legs, a sacroiliac joint injection involves injecting local anaesthetic and/or steroid into the joint. This injection helps diagnose the source of pain and can provide pain relief for several weeks or months.
HOW IS THE PROCEDURE PERFORMED?
During your procedure, an anaesthetist will provide intravenous sedation for relaxation. This minimally invasive process is conducted in a hospital theatre or day procedure centre with specialised imaging guidance. This allows your doctor to safely position a needle near the nerves supplying the sacroiliac joint and administer a small amount of local anaesthetic and/or steroid.
HOW LONG DOES THE EFFECT LAST?
The duration of pain relief will vary from person to person. In some cases, it may last for months and in other cases, it may last only weeks or even days. Some people receive multiple therapeutic SI joint injections over the course of several years and the duration of relief may diminish with each injection.
WHAT SHOULD BE DONE BEFORE THE PROCEDURE?
Prior to the procedure, you may need to stop blood thinning products as directed by your doctor. Other regular medications can be taken with a sip of water on the morning of the procedure. Insulin-dependent diabetics will likely be prioritised on the list and should bring their insulin for potential administration after the procedure. Hospital staff will call you the day before the procedure to provide fasting and admission times. DO NOT eat, drink, smoke, or chew gum before the procedure. Arrange for someone to drive you home afterward, as you won’t be able to drive for 24 hours due to the received anaesthesia.
WHAT IS THE NEXT STEP AFTER THE PROCEDURE?
After a short time in the recovery ward, you will be discharged home. Minimise strenuous activity for 1 to 2 weeks, then resume normal activity as tolerated. You can shower 24 hours after the procedure with the waterproof dressing on, and you can remove the dressing after 3 days. Expect a temporary increase in pain for 1 to 3 weeks post-procedure. A follow up appointment with Dr. Mohabbati will be scheduled in approximately 6 weeks, or sooner if needed.
WHAT ARE THE RISKS AND SIDE EFFECTS?
Serious side effects and complications are rare. The most common problem after the procedure is having pain in the area of the procedure for 1 to 3 weeks. Please contact your local GP or the rooms if you have any allergic reaction to the medication administered in hospital, signs of infection at your procedure site.
