A novel anterior approach for ultrasound-guided lumbar plexus combined with sacral plexus blocks with one-point puncture

Editor—Traditional ultrasound-guided lumbar plexus block combined with sacral plexus block requires separate blocks at different sites, which increases the complexity of the manipulation and adds patient discomfort.1,2 Traditionally these techniques are always performed with the posterior approach, requiring the lateral decubitus or prone position, which may be suboptimal in patients with severe pain, spinal fractures, or risk of reinjury. To address these issues, we present a novel anterior approach for combined lumbar plexus and sacral plexus blocks with one-point puncture.
