Anterior superior iliac spine

The anterior superior iliac spine is an important bony surface landmark and is the prominence is the most anterior part of the ilium. It can be palpated at the lateral end of the inguinal fold. Attachments include the inguinal ligamentsartorius and depending on which resource you read, the tensor fasciae latae.

Clinically, as an easily identifiable landmark, it aids in the localization of the inguinal ligament, common femoral artery and the base of the appendix (McBurney's point). It is also the start point for the measurement of true leg length (anterior superior iliac spine to medial malleolus).
