The caudal approach to the epidural space involves the use of a Tuohy needle, an intravenous catheter, or a hypodermic needle to puncture the sacrococcygeal membrane . Injecting local anaesthetic at this level can result in analgesia and/or anaesthesia of the perineum and groin areas. The caudal epidural technique is often used in infants and children undergoing surgery involving the groin, pelvis or lower extremities. In this population, caudal epidural analgesia is usually combined with general anaesthesia since most children do not tolerate surgery when regional anaesthesia is employed as the sole modality.
We note these studies not to discourage you from undergoing epidural steroid injections, but rather to help foster well-rounded discussions with your doctor. These injections have been shown to provide excellent pain relief in many patients (particularly those who have had symptoms for less than 3 months, not had a previous spine surgery, are younger than 60 years, and don’t smoke). However, epidural steroid injections are not magic bullets. Before starting injection therapy, talk to your doctor about the specific risks and benefits for you.
