Iliac fascia

Iliac fascia is a fibrous membrane that covers the Iliacus muscle in the pelvic region. It is a part of the Fascia system, a network of connective tissues that envelops, separates, or binds together muscles, organs, and other soft structures of the body.

Etymology

The term "Iliac" is derived from the Latin word "ilium," which refers to the broad, upper portion of the hip bone. "Fascia" is a Latin term meaning "band" or "bandage," which describes the tissue's band-like appearance.

Anatomy

The Iliac fascia covers the Iliacus muscle and forms the medial boundary of the Iliac fossa. It is thickened above to form the medial arcuate ligament. The fascia is attached to the inner lip of the iliac crest, and to the lateral part of the anterior margin of the ala of the sacrum, covering the front and sides of the Psoas major muscle and the Iliacus muscle, and binding them down to the pelvic brim.

Clinical Significance

The Iliac fascia is clinically significant as it is often involved in surgical procedures involving the pelvic region. It is also a potential space for the spread of infections or malignancies.
