Anterior superior iliac spine
The anterior superior iliac spine (ASIS) is a prominent and palpable bony projection of the ilium. It is the most anterior part of the ilium and also marks the anterior aspect of the iliac crest, which spans from the ASIS to the posterior superior iliac spine.
The ASIS serves as an attachment point for the sartorius and tensor fasciae latae muscles, as well as the lateral end of the inguinal ligament. As it is easily palpable, it clinically serves as an important bony landmark for localizing the inguinal ligament, common femoral artery and base of the vermiform appendix. It is also used as the proximal landmark for measuring true lower limb length.
