Total hip replacement produces significant postoperative pain. Psoas compartment block is the most effective block of the lumbar plexus in terms of pain relief and reduced blood loss. It is a proven regional technique for analgesia and anaesthesia during and after total hip replacement conferring a number of benefits to the patient. However, traditional techniques used to produce this block require increased theatre time and are associated with a number of serious complications. We present a surgeon‐delivered technique for producing a lumbar plexus block using direct injection into the iliopsoas muscle when it is visible intraoperatively. This study shows a cadaveric model using methylene blue and radiopaque contrast produces injectate spread in a fashion which would produce a successful lumbar plexus block. This novel technique for lumbar plexus block affords the benefits of psoas compartment block with reduced complications and reduced administration time. Clin.
