AbstractLumbar discography, a useful modality for evaluating patients with lower back pain, is performed under fluoroscopy with posteroanterior and lateral fluoroscopic imaging. Despite use of fluoroscopy, needle placement into the L5-S1 disc may be difficult, especially in the presence of degenerative changes. We describe use of angled posteroanterior fluoroscopy with the fluoroscopy beam directed 30 degrees to 40 degrees caudally in a prone patient for clear visualization of the L5-S1 disc space. Use of this radiographic view aids in accurate needle placement and might decrease both procedure duration and fluoroscopic exposition.
