Study objective We report a novel block technique aimed to provide lumbosacral, abdominal, and hip analgesia: The quadro-iliac plane (QIP) block.Design A cadaveric examination that evaluates the spread of QIP block.Setting Cadaver laboratory.Patients One unembalmed cadaver.Interventions Bilateral ultrasound-guided QIP blocks on cadavers with 40 mL of methylene blue %0.5 each side.Measurements Dye spread in cadaver.Main results There was staining in the deep interfascial plane of the erector spinae muscles. Extensive staining of the interfascial plane corresponding to the posterior aspect of the quadratus lumborum muscle (QLM) was observed. There was extensive staining on the anterior surface of the QLM. There was spread of dye traversing along the transversalis fascia and significantly infiltrating retroperitoneal fat tissue. Bilateral staining of the ilioinguinal and iliohypogastric nerves was observed. On the right, there was minimal staining over the subcostal nerve. There was dye present bilaterally within the deep regions of the transverse processes. The lumbar plexus was stained on both sides.Conclusion The local anesthetic applied from a place where the QLM reaches its largest volume and the fascial plane creates a closed gap in the caudal area may exhibit a more rounded and extensive spread. Quadro-iliac plane block, involves the administration of local anesthetic to the posterior aspect of the QLM at its origin from the iliac crest. According to our cadaver study, this technique may be a promising option for alleviating acute and chronic pain in the lumbosacral, lower abdominal, and hip regions.Conclusion The local anesthetic applied from a place where the QLM reaches its largest volume and the fascial plane creates a closed gap in the caudal area may exhibit a more rounded and extensive spread.
