anterior superior iliac spine

The anterior superior iliac spine refers to the anterior extremity of the iliac crest of the pelvis. This is a key surface landmark, and easily palpated. It provides attachment for the inguinal ligament, the sartorius muscle,{{Citation|last=Jacob|first=S.|title=Chapter 6 - Lower limb|date=2008-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780443103735500099|work=Human Anatomy|pages=135–179|editor-last=Jacob|editor-first=S.|publisher=Churchill Livingstone|language=en|doi=10.1016/b978-0-443-10373-5.50009-9|isbn=978-0-443-10373-5|access-date=2020-12-15}} and the tensor fasciae latae muscle.

A variety of structures lie close to the anterior superior iliac spine, including the subcostal nerve, the femoral artery (which passes between it and the pubic symphysis), and the iliohypogastric nerve.{{Citation|last=Mirjalili|first=S.

The anterior superior iliac spine provides a clue in identifying some other clinical landmarks, including McBurney's point, Roser-Nélaton line, and true leg length. It is an important surface landmark for various surgical approaches, such as treatment of hernia.{{Citation|last=Molloy|first=Robert E.|title=Chapter 75 - Truncal Blocks: Intercostal, Paravertebral, Interpleural, Suprascapular, Ilioinguinal, and Iliohypogastric Nerve Blocks|date=2005-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780443066511500794|work=Essentials of Pain Medicine and Regional Anesthesia (Second Edition)|pages=636–644|editor-last=Benzon|editor-first=Honorio T.|place=Philadelphia|publisher=Churchill Livingstone|language=en|doi=10.1016/b978-0-443-06651-1.50079-4|isbn=978-0-443-06651-1|access-date=2020-12-15|editor2-last=Raja|editor2-first=Srinivasa N.|editor3-last=Molloy|editor3-first=Robert E.|editor4-last=Liu|editor4-first=Spencer S.}} The severity of symptoms of damage to the iliohypogastric nerve can show whether damage occurred above or below the anterior superior iliac spine.

Bone may be harvested from the nearby iliac crest for use elsewhere in the body.{{Citation|last=Rea|first=Paul|title=Chapter 3 - Lower Limb Nerve Supply|date=2015-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780128030622000036|work=Essential Clinically Applied Anatomy of the Peripheral Nervous System in the Limbs|pages=101–177|editor-last=Rea|editor-first=Paul|publisher=Academic Press|language=en|doi=10.1016/b978-0-12-803062-2.00003-6|isbn=978-0-12-803062-2|access-date=2020-12-15}} As the subcostal nerve lies close to the anterior superior iliac spine, this is put at risk of damage.

The iliotibial tract may be irritated where it passes over the anterior superior iliac spine in iliotibial band syndrome.

The line around anterior superior iliac spine is sometimes called the panty line or "bikini line".{{cite journal | last=Kim | first=Ji Hun | title=Robotic cholecystectomy with new port sites | journal=World Journal of Gastroenterology | volume=19 | issue=20 | date=2013 | issn=1007-9327 | pmid=23716987 | pmc=3662947 | doi=10.3748/wjg.v19.i20.3077 | doi-access=free | page=3077}} It is considered to be a "discreet" location for concealing cosmetic surgery scars and ports.{{cite journal | last=Leggett | first=P.L. | last2=Bissell | first2=C.D. | last3=Churchman-Winn | first3=R. | title=Cosmetic minilaparoscopic cholecystectomy | journal=Surgical Endoscopy | volume=15 | issue=10 | date=2001 | issn=0930-2794 | doi=10.1007/s004640041018 | pages=1229–1231}}
