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, [1] [4] and the tensor fasciae latae muscle. [2] [3]
Laterally, the ligament attaches onto the posterior part of the inner lip of the iliac crest. [1] More precisely, its lateral attachment is by two main bands: [2] the superior band (which is one of the attachments of the quadratus lumborum muscle) attaches onto the iliac crest anterior to the sacroiliac joint.
The iliac crest has a large amount of red bone marrow, and thus it is the site of bone marrow harvests (from both sides) to collect the stem cells used in bone marrow transplantation. The iliac crest is also considered the best donor site for bone grafting when a large quantity of bone is needed.
The quadratus lumborum muscle originates by aponeurotic fibers into the iliolumbar ligament and the internal lip of the iliac crest for about 5 centimetres (2.0 in). It inserts from the lower border of the last rib for about half its length and by four small tendons from the apices of the transverse processes of the upper four lumbar vertebrae.

The iliac fascia (or Abernethy's fascia [citation needed]) is the fascia overlying the iliacus muscle. [1]Superiorly and laterally, the iliac fascia is attached to the inner aspect of the iliac crest; inferiorly and laterally, it extends into the thigh to unite with the femoral sheath; medially, it attaches to the periosteum of the ilium and iliopubic eminence near the linea terminalis, and ...
Below the notch is the anterior inferior iliac spine, which ends in the upper lip of the acetabulum; it gives attachment to the straight tendon of the rectus femoris and to the iliofemoral ligament of the hip-joint. Medial to the anterior inferior spine is a broad, shallow groove, over which the iliacus and psoas major pass.
