The anterior superior iliac spine (ASIS) is an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis, which provides attachment for the inguinal ligament, and the sartorius muscle. The Tensor Fasciae Latae muscle attaches about 5cm away at the iliac tubercle.
ASIS provides a clue in identifying some other clinical landmarks, including:
- McBurney's point
- Roser-Nélaton line
A – Anterior (front, like the face)
S – Superior (towards the head, opposite to feet)
I – Iliac (Pelvis bone)
S – Spine

“I find it more credible, since it is anterior information, that one man should know heaven, as the Chinese say, than that so many men should know the world.”

“For by superior energies; more strict
Affiance in each other; faith more firm
In their unhallowed principles, the bad
Have fairly earned a victory o’er the weak,
The vacillating, inconsistent good.”
—William Wordsworth (1770–1850)
“Much of a man’s character will be found betokened in his backbone. I would rather feel your spine than your skull, whoever you are. A thin joist of a spine never yet upheld a full and noble soul.”
