    AbstractThe transmuscular quadratus lumborum (TQL) block is one of the recently evolved myofascial blocks utilised in abdominal surgery. It involves injecting local anaesthetic into the fascial plane anterior to the thoracolumbar fascia. This block has previously been described with a transverse oblique paramedian approach at the L2 level in the sitting position. We describe a TQL block at the same level in the lateral position using a transverse posterolateral approach to provide analgesia for patients undergoing abdominal surgery. We elaborate on these two approaches of TQL block at the L2 level, in relation to the anatomy, sonoanatomy and technical aspects.
