Sacral Lateral Branch Blocks
Description
A sacral lateral branch block is a diagnostic injection used to determine if your back pain is originating from small nerves that act as pain receptors to the sacroiliac joint. Since the sacroiliac joint is innervated by multiple nerves, the sacral lateral branch block is performed at several points along your low back to address as many of these small nerves as possible. Only your right side or left can be injected at one time.
How it is performed
You will be lying on your stomach for the procedure. After the skin along the injection site is well cleansed, up to 4 needles will be placed into your low back near your buttock. The injection is performed under x-ray guidance to confirm that the needle has reached the appropriate area in your back. The injection contains an anesthetic (numbing agent) which temporarily numbs the small nerves. Contrast medication is often used during x-ray to ensure the medication is reaching the appropriate spot.
The potential benefits
It is important to understand that the goal of this injection is to provide temporary relief of your left or right-sided low back pain. If you experience pain relief following the injection, it is usually lasts for several hours and wears off by the next day. The injection is a test procedure to see if you are a candidate for further treatment. If significant temporary pain relief occurs following the procedure, then you may be a candidate for a treatment called radiofrequency neurotomy, which is a procedure that deadens those nerves and can provide much longer pain relief.
The potential risks
Fortunately, the risks of the injection are much lower than the risks of surgery. If side effects occur, they usually resolve on their own within a few days. The most common side effects are temporary soreness at the injection site or a temporary numbness or tingling sensation along the back or buttock. Potential complications can include, but are not limited to, problematic bleeding, nerve damage, or infection. However, these complications rarely occur. There is also a risk that not all of the nerves can be injected during the procedure, due to possible difficulty with visualization under x-ray guidance. In order to reduce this risk and to make sure we get the best result possible from the procedure, we strongly encourage you to follow the “Special Diet” described on your procedure instruction sheet.
What to expect after the procedure
After the injection is completed, you will wait in the recovery room for at least 10 minutes if you did not receive IV sedation for the procedure, or at least 30 minutes if you received IV sedation. When preparing to leave from the facility, you will be given a written sheet containing more detailed discharge instructions. You should make a follow up appointment 1-2 days after the injection, to discuss the results of the injection and to develop a corresponding treatment plan.
