Iliac region

Iliac region refers to the area of the lower abdomen on either side of the pelvis, specifically overlying the iliac fossa. The iliac region is an important anatomical and clinical area, as it contains structures such as the iliac crest, iliac artery, and iliac vein, as well as being a key landmark for various surgical procedures.

Anatomy[edit | edit source]

The iliac region is divided into two main parts: the right iliac region and the left iliac region. These regions are also known as the right and left inguinal regions, respectively. The iliac fossa is a shallow depression located on the inner surface of the ilium, the largest bone of the pelvis. The iliac crest, which forms the upper border of the iliac fossa, serves as an important landmark for the division of the abdominal area into quadrants and regions for clinical and diagnostic purposes.

Clinical Significance[edit | edit source]

The iliac region is of significant clinical importance due to its contents and its proximity to other vital structures. It is a common site for the manifestation of various conditions, including appendicitis, in the right iliac region, and diverticulitis in the left iliac region. Additionally, the iliac arteries and veins, which are major blood vessels in the body, are located in this region, making it a critical area in vascular surgery and interventions.

Surgical Relevance[edit | edit source]

The iliac region is a key landmark in several surgical procedures, including appendectomy, the surgical removal of the appendix, and various types of hernia repairs. The region's anatomy is also crucial in procedures involving the pelvic bones, such as fracture repairs and hip replacements.
