The Lumbar Transforaminal Epidural Steroid Injection Procedure
A Lumbar Transforaminal Epidural Steroid Injection is a commonly used procedure in interventional pain management. With x-ray guidance, a needle is guided into the nerve root at the point where it exits the spinal cord through a small hole called the foramina. Placing the steroid specifically at that level of the nerve between where the disc or a bone spur might be pinching it will alleviate the back pain as well as pain that radiates to the legs.
Indication for transforaminal injection is usually persistent low back pain that radiates to the legs and has failed to improve with more conservative treatments, specifically when a herniated disc is impinging upon the nerve root. A series of anywhere from one to three injections is usually necessary determine whether there is significant improvement that is long lasting, which is the goal.
