Ultrasound-Guided Lumbar Nerve Root (Periradicular) Injections
Lumbar periradicular infiltrations (nerve root blocks) are well established in the diagnosis and management of lumbar radiculopathy. Lumbar periradicular injections are preferentially performed as fluoroscopically or computed tomography (CT) controlled interventions. However, both guidance modalities have significant radiation exposure, at least in part, expensive equipment. As an alternative guidance method, ultrasound (US) imaging is also applicable for spinal infiltrations– and for lumbar periradicular injections.
