ABSTRACT: Study Design. Preclinical feasibility studyObjective. Evaluation and validation of ultrasound-guided lumbar transforaminal injectionsSummary of Background Data. Lumbar transforaminal injections are commonly performed in the interventional management of spinal radicular pain. Typically these injections are performed under radiological guidance, most commonly utilizing fluoroscopy or computed tomography. Although radiological guidance provides anatomical precision and accuracy it is associated with radiation exposure and cannot be performed during outpatient visits or at bedside. Ultrasound-guided techniques have been previously described; however the methodological generalizability remained unknown and validation against routine fluoroscopy has never been conducted on multiple spinal levelsMethods. We addressed the procedural accuracy of ultrasound-guided lumbar transforaminal injections and proposed anatomically sound approach. Fluoroscopic validation was performed.Results. Out of 50 planned injections 46 procedures were performed. L5/S1 foraminal access was impossible in four cases (8%). Fluoroscopy confirmed the correct foraminal placement in all 46 injections (100%). The contrast spread pattern was intraforaminal in 42 cases (91.3%) and extraforaminal (nerve root) in four cases (8.7%). When intraforaminal pattern was detected on anteroposterior image, lateral fluoroscopy demonstrated ventral epidural flow in all occasions. In three cases, intravascular injection was detected (6.5%)Conclusion. Ultrasound-guided lumbar transforaminal injections are accurate and feasible in the preclinical setting.
