The word caudal means near the tail or posterior side of the body. A caudal steroid injection is an injection administered to the most distal or lowest epidural space on the spine. The epidural space is the space around the dura which is the protective sheath of the spine. An injection of steroids is used in this area to relieve low back and leg pain. The most common causes of this pain are: Sciatica, bone spurs, disc herniations and arthritis.
The Sciatic nerve is the largest nerve in the body and can get entrapped like other nerves by bones but also often gets entrapped by the Piriformis muscle. It is so large that it’s pathway travels all the way down the back of the leg to the foot. True Sciatica has radiating pain down some or all of this pathway. Bone spurs and arthritis are degenerative in nature and brought on through excessive wear and tear. Disc herniations can be due to degeneration or injury. Many patients respond to Chiropractic, Physical Therapy, Acupuncture and other less invasive care. However if Sciatica is unresponsive a Caudal Steroid Injection can provide relief fast!
