Is rib an alternative landmark for ESPB instead of a transverse process? A little more lateral injection, lateral to the fascial plane

Abstract

Dear Editor,We have read with great interest the article by Mislovic et al.1 The authors used a new terminology named Lateral Erector Spinae Plane Block (LESPB) with this manuscript. They reported that due to the anatomical variation caused by previous spinal surgery, it is impossible to visualize the transverse process (TP). So, the authors decided to move the probe laterally until it shows the thoracic rib and deposits the local anesthetic after contacting the rib instead of the TP. In addition, they named this block LESPB.
