Injectate spread following anterior sub-costal and posterior approaches to the quadratus lumborum block: A comparative cadaveric study

CONCLUSIONS: Our cadaveric study demonstrates that injection of dye on the posterior aspect of quadratus lumborum muscle led to injectate spread through the lateral and posterior abdominal wall but with limited cranial spread, whereas the anterior approach produced broader coverage of the lower to mid-thoracic region. Clinical translation of these findings to determine the practical significance is warranted.
