In this procedure a steroid-anesthetic medication is injected into a sacrum opening to alleviate the pain of inflamed nerves in the spine. To prepare for this procedure the patient will lay face down over a cushion placed on the abdomen to raise the sacrum. Once the preparation is completed an anesthetic injection will be administered to numb the affected area. Upon effectively numbing the Sacral hiatus, the physician will direct a needle to the location of the irritated nerve roots and inject a contrast solution. Using an x-ray device called a fluoroscope the physician will ensure that the placement is correct and will then inject the medication. It takes a few minutes to administer the injection and once completed the patients pain should be immediately relieved. In some cases, more than one injection will be needed for full benefit to be felt by the patient.
