Anterior superior iliac spine

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, and the tensor fasciae latae muscle. == 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. The severity of symptoms of damage to the iliohypogastric nerve can show whether damage occurred above or below the anterior superior iliac spine. As the subcostal nerve lies close to the anterior superior iliac spine, this is put at risk of damage. It is considered to be a "discreet" location for concealing cosmetic surgery scars and ports. == Additional images ==
