For the subcostal QL block (subtype of anterior QL block), the local anesthetic injected anterior to the QL between the QL muscle and the anterior layer of the thoracolumbar fascia observed the spread in cephalad direction close to the T12 rib with anterior displacement of the anterior layer of thoracolumbar fascia. This produces reliable dermatomal coverage from T6-T7 to L1-2 [13].
