Sacroiliac Joint Injection is an outpatient procedure used in the diagnosis and treatment of pain in the lower back and buttocks. The process involves injecting a local anesthetic and an anti-inflammatory drug like corticosteroid into at least one of the sacroiliac joints or the ligaments in the surrounding area. For the procedure to be as safe as possible, an x-ray technique known as fluoroscopy is used to position the needle accurately. The doctor may also inject dye to help situate the needle into the joint. Only once the doctor is happy with the needle insertion will the medication be introduced.
After the procedure, it takes between 48 and 72 hours to experience the effects of the long-lasting anti-inflammatory agent. The actual results will vary between individual patients, regarding the duration and extent of the pain relief. Some of the factors that could have an impact on how effective is the treatment include the patient’s medical history and current level of activity. The most successful treatments can last for several years, but some patients may only have short term relief from their pain.
