Commonly, the procedure is performed without any sedation at Portland Pain & Spine, however, an IV line can be started if relaxation medicine is needed. The patient lies on a procedure table, and the skin over the area to be tested is well cleansed.
The physician treats a small area of skin with numbing medicine (anesthetic), which may sting for a few seconds. The physician uses X-ray guidance (fluoroscopy) to direct a very small needle into the facet joint.
A small amount of contrast dye is then injected to confirm that the needle is in the joint and that medication is contained inside the joint. Following this confirmation, a small mixture of anesthetic (such as lidocaine) and anti-inflammatory medication (steroid/cortisone) is then slowly injected into the joint.
