Evaluation of Transforaminal Epidural Steroid Injection in Radicular Low Back Pain According to MSU Classification

"Epidural injections have been used since about 1900 for the treatment of low back and lower extremity pain, with steroids added to local anesthetics in about 1950. The epidural space can be entered by 3 approaches: caudal, interlaminar, and transforaminal. Transforaminal Epidural Steroid Injections:~After the patient is monitored in pron position and asepsis is ensured, the epidural space is entered with the appropriate needle through the transforaminal space by giving the necessary angles to the fluoroscopy. Then the location is confirmed with radiopaque agent and steroid injection is performed. The procedure takes 15-20 minutes."
