The lateral arcuate ligament (also lateral lumbocostal arch) is a ligament under the diaphragm that arches across the upper part of the quadratus lumborum.

Structure

The lateral arcuate ligament runs from the front of the transverse process of the first lumbar vertebra, and, laterally, to the tip and lower margin of the twelfth rib. It forms an arch over the quadratus lumborum muscle.
