Brief Summary

Lumbar plexus block is described as a difficult block, thus requiring experienced practitioners. Many techniques have been used to date, notably anatomical landmarks, neurostimulation, and ultrasound-guided techniques. Among ultrasound-guided techniques, the "Trident" technique was described in 2006, while the "Shamrock" technique was described in 2013. Trident consists in putting the probe sagittally next to the lumbar spine and injecting local anesthetic around the lumbar plexus inside the psoas muscle at the level of L4. It is an out-of-plane puncture. Shamrock puts the probe transversely on the iliac crest. Authors of the 2013 article said the image obtained with this technique was an image of L4. This technique allows an in-plane puncture, which is a safe technique.

Analysis lumbar echographies results by Trident ans Shamrock techniques. Costiform processes on T12 to L5 were spotted and noted. For Trident technique, quality of image, depth of lumbar plexus and presence of vessels were noted. Shamrock technique was performed, the projection of C line (line obtained with a probe put on the iliac crest) was noted with the invisible ink pen. Then the probe was oriented cephalically (for line \>C) and caudally (line \<C). For each lines, quality of image, depth of lumbar plexus and presence of vessels were also noted. The projections of C, \>C, \<C on the costiform processes were noted.
