Lateral Branch Blocks

To successfully diagnose sacroiliac joint pain, we temporarily block the nerves associated with sacroiliac joint discomfort with a local anaesthetic.

Lateral Branch Blocks are performed by an anaesthetist injecting a small dose, under x-ray guidance to provide light sedation. The local anaesthetic is placed under the sacrum (tailbone) where the lateral branch nerves are located.

If your pain significantly alleviates over the period of treatments given, it is safe to diagnose the sacroiliac joint as the site of its origin. Once diagnosed, your doctor will consider longer-lasting treatments to further alleviate sacroiliac joint pain.

Following initial treatments, we may ask you to keep a “Pain Diary” to record the effectiveness of treatments following the procedure.
