Randomized Controlled TrialSoft tissue depression at the iliac crest prominence: a new landmark for identifying the L4-L5 interspace.
One of the most common approaches to identifying the L4-L5 interspace is using the iliac crest as a landmark. We propose a new landmark to identify the L4-L5 interspace based on the soft tissue depression palpable at the iliac crest prominence. The aim of this study was to assess the reliability and time saving when using this new landmark compared to using the iliac crest to perform a lumbar plexus block. ⋯ Use of the palpable soft tissue depression at the iliac crest prominence for performing a lumbar plexus block offered several potential advantages over the standard inter-iliac crest approach.
