The rhombus of Michaelis, also known as the Michaelis-Raute or the quadrilateral of Michaelis, is a rhombus-shaped contour (also referred to as kite-shaped or diamond-shaped) that is sometimes visible on the lower human back. The rhombus is defined by the following vertices: dimples of Venus, the top of the gluteal crease (S5 vertebral body level), and the lower end of the posterior median furrow (spinous process of the 5th lumbar vertebra).
