Sacroiliac Joint Injection

A sacroiliac joint injection is an injection of local anesthetic and a steroid medication into the sacroiliac joint. Due to the numbing medicine used during this procedure, you may experience temporary pain relief afterwards that may last several hours. Once the numbing medicine wears off, however, your pain will most likely return. The steroid medication may give longer lasting pain relief and usually begins working after 24-48 hours.

Most patients say Sacroiliac Joint Injection have a stinging/burning of the numbing medicine is the most uncomfortable part of the procedure (this lasts only a few seconds); however, every person’s response to any procedure will differ.

During the sacroiliac joint injection procedure patients are assisted to the X-ray table and made as comfortable as possible lying on your stomach. Your injection site is cleansed with an antiseptic soap and alcohol, and then covered by sterile drapes. The skin is numbed with local anesthetic (numbing medicine). Using X-ray guidance, a needle is advanced into the sacroiliac joint. X-ray dye will be injected to confirm proper placement. Local anesthetic (numbing medicine) and steroid are then injected into the joint, and the needle is removed. The injection site will be washed and a Band-Aid will be applied. You will be monitored for an appropriate time in the recovery area (usually 20-30 minutes) where you may be offered juice/soda and graham crackers. You will be given verbal and written discharge instructions, and may go home with your driver after your doctor authorizes discharge.

Your pain may be improved immediately after the injection from the local anesthetic. Once the numbing medicine wears off, your pain may return. It is possible that you will have some soreness at the injection site and your pain may worsen for a day or two after the procedure. The steroid medication takes 2-3 days to start having an effect in most people. Using an ice pack applied three or four times a day can help alleviate the discomfort at the injection site. You may take your usual pain medication after the injection.
