Abstract: Background: Transforaminal nerve root injection of L4 is part of the management of low back pain caused by radiculopathy. This study was determined the accuracy and successful rate of ultrasound guided lumber transforaminal epidural injection which was validated by conventional fluoroscopic technique. Aim: the aim of study to determine the accuracy of needle position under US guidance and confirmed with fluoroscopy in patient who subject transforaminal nerve root injection. Patient and Method: A total of 20 patients with L4 disc prolapse causes radiculopathy were recorded. Using transforaminal route , the needle position was detected by axial and longitudinal view of the ultrasound with fluoroscopic conformation .We detected the needle position accuracy of ultrasound guided lumber transforaminal injection approach. Result: The successful rate of ultrasound guided interventions was 95% as confirmed by fluoroscopy. There was only one failed case in the ultrasound guided. Conclusion: Ultrasound guided lumber transforaminal epidural injections are accurate and practical in clinical cases with successful rate of 95%. US guidance has decreased radiation exposure and decreased need of operative room to significant level in this study.
