Anatomical terminology

The dimples of Venus (also known as back dimples, butt dimples or Venusian dimples) are sagittally symmetrical indentations sometimes visible on the human lower back, just superior to the gluteal cleft. They are directly superficial to the two sacroiliac joints, the sites where the sacrum attaches to the ilium of the pelvis.

Overview

The term "dimples of Venus", while informal, is a historically accepted name within the medical profession for the superficial topography of the sacroiliac joints. The Latin name is fossae lumbales laterales ("lateral lumbar indentations"). These indentations are created by a short ligament stretching between the posterior superior iliac spine and the skin.

Named after Venus, the Roman goddess of beauty, they are sometimes believed to be a mark of beauty. The features may be seen on both female and male backs, but seem to be more common and more prominent in women.

There are other deep-to-superficial skin ligaments, such as "Cooper's ligaments", which are present in the breast and are found between the pectoralis major fascia and the skin.

Another use of the term "dimples of Venus" in surgical anatomy refers to two symmetrical indentations on the posterior aspect of the sacrum, which also contain a venous channel. They are used as a landmark for finding the superior articular facets of the sacrum as a guide to place sacral pedicle screws in spine surgery.[2]
