It has the following connections:
- laterally, to the whole length of the inner lip of the iliac crest.
- medially, to the linea terminalis of the lesser pelvis, where it is continuous with the periosteum.
Immediately lateral to the femoral vessels the iliac fascia is prolonged backward and medialward from the inguinal ligament as a band, the iliopectineal fascia, which is attached to the iliopectineal eminence.
This fascia divides the space between the inguinal ligament and the hip bone into two lacunæ or compartments:
- the medial vascular lacuna transmits the femoral vessels.
- the lateral muscular lacuna transmits the Psoas major and Iliacus and the femoral nerve.
