Clinical experience of anterior quadratus lumborum block after lumber surgery

Anterior quadratus lumborum block (QLB) is reported as one of trunk nerve block [1]. In addition, because anterior QLB injects a local anesthetic between the psoas (PM) and the quadratus lumborum (QB), the anterior QLB may be able to block lumbar plexus nerves. Therefore it may be effective for a postoperative pain of lower surgery [2]. In this time, we report one successful case of open reduction internal fixation (ORIF) of left femur fracture by performing only the anterior QLB for the patient with a lumber surgery.
