Bony projection of the iliac bone
The anterior superior iliac spine (ASIS ) is a bony projection of the
iliac bone , and an important landmark of
surface anatomy . It refers to the anterior extremity of the
iliac crest of the
pelvis . It provides attachment for the
inguinal ligament , and the
sartorius muscle .
[1] The
tensor fasciae latae muscle attaches to the lateral aspect of the superior anterior iliac spine, and also about 5
cm away at the
iliac tubercle .

Structure
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 ,
[1]
[4] and the
tensor fasciae latae muscle .
[2]
[3]
A variety of structures lie close to the anterior superior iliac spine, including the
subcostal nerve ,
[5] the
femoral artery (which passes between it and the
pubic symphysis ),
[4] and the
iliohypogastric nerve .
[6]
Clinical significance
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 .
[7] The severity of symptoms of damage to the
iliohypogastric nerve can show whether damage occurred above or below the anterior superior iliac spine.
[6]
Bone may be
harvested from the nearby iliac crest for use elsewhere in the body.
[5] As the
subcostal nerve lies close to the anterior superior iliac spine, this is put at risk of damage.
[5]
The
iliotibial tract may be irritated where it passes over the anterior superior iliac spine in
iliotibial band syndrome .
[3]
The line around anterior superior iliac spine is sometimes called the panty line or "bikini line".
[8] It is considered to be a "discreet" location for concealing cosmetic surgery scars and
ports .
