Supracristal plane

Supracristal plane (Planum supracristale) (or supracrestal plane) is an anatomical transverse plane lying at the upper most part of the pelvis, the iliac crest. According to Gray's Anatomy, this anatomical plane crosses the upper border of the spinous process of L4 (fourth lumbar vertebra).[1] It lies about half an inch below the level of the transumbilical plane and therefore passes through the umbilical region and the left and right lumbar regions.
