Gluteal sulcus

Gluteal Sulcus

The Gluteal Sulcus (also known as the Gluteal Crease or Buttock Crease) is a horizontal line or crease formed by the inferior aspect of the buttocks and the posterior upper leg. It is a prominent feature of the human anatomy, particularly in the posterior view.

Etymology

The term "Gluteal" is derived from the Latin word "Gluteus", meaning buttock, while "Sulcus" is a Latin word that translates to "groove" or "furrow". Thus, the term "Gluteal Sulcus" essentially refers to the groove or furrow of the buttock.

Anatomy

The Gluteal Sulcus is formed by the meeting point of the gluteus maximus muscle and the posterior thigh. It is more pronounced and visible when the hip is extended due to the tension created in the fascia and skin. The Gluteal Sulcus is not a bony landmark but is significant in the clinical setting for procedures such as intramuscular injections and surgeries.

Clinical Significance

The Gluteal Sulcus serves as a landmark for several medical procedures. For instance, it is used as a reference point for administering intramuscular injections in the gluteal region. It is also significant in plastic and reconstructive surgeries, particularly in procedures such as gluteal augmentation and gluteoplasty.
