A RACZ Caudal Neurolysis is an outpatient procedure done under local anesthesia to help relieves pain in the lower back region as well as leg pain. This pain often caused by scarring from a previous surgery.
With a pillow or cushion placed under the stomach, the patient lays face down during the procedure. Locating the small opening of the sacrum or sacral hiatus, the physician administers a local anesthetic to numb the skin and tissue. The local anesthetic reaches all the way down to the surface of the sacral hiatus. Through the anesthetized track, the physician slides the needle down and into the epidural space. Using a contrast solution, the physician is able to see scarred or painful areas with an x-ray like device called a fluoroscope.
Feeding through the needle, a small catheter positioned at the location of the scarring. Then a combination of steroid-anesthetics injects through the catheter as well as around the scarring and painful areas. The medication dissolves the scar tissue.
Once the procedure is complete, the removal of the needle and catheter is completed. Sometimes, to allow for more injections, the catheter kept in place. In necessary, repeating the procedure months later to continue to reduce scar tissue.
