The caudal epidural procedure is a medical treatment commonly used to manage lower back pain. This minimally invasive technique involves injecting an anesthetic and/or steroid medication into the epidural space in the lower back region. By doing so, the medication can help relieve inflammation and pain in the nerves, muscles, and tissues in the area.
Pulsed radiofrequency (PRF) is a newer technique that can also be used to manage chronic lower back pain. Unlike traditional radiofrequency ablation, which uses high-frequency currents to destroy problematic nerves, PRF instead sends short pulses of electrical signals to the targeted nerves to interrupt and decrease pain signals. PRF has been shown to be a safe and effective way to manage lower back pain, especially in patients who have not responded well to other treatments. In some cases, PRF may be used in addition to a caudal epidural procedure to provide longer-lasting relief of lower back pain.
I have included some studies about caudal epidural PRF which I have used in my practice with quite good result.
