Which pelvic landmark is located at the anterior superior aspect of the ilium and commonly palpated?

• A. Iliac Crest
• B. ASIS
• C. PIIS
• D. Pubic Symphysis

Answer: (B)

The anterior superior iliac spine is a bony projection on the front-top edge of the ilium. It’s commonly palpated because it sticks out prominently at the front of the pelvis, making it a reliable surface landmark for orientation and for guiding measurements or assessments of pelvic alignment. It also marks important anatomical connections: the inguinal ligament runs from this point to the pubic tubercle, and the sartorius muscle originates nearby, contributing to its firm, palpable feel. In contrast, the iliac crest is the curved upper border of the ilium felt along the waistline, not the most anterior point. The posterior superior and posterior inferior spines lie toward the back of the pelvis and are not the typical front landmarks. The pubic symphysis is at the front midline between the two pubic bones, not on the ilium itself.
