Medical Definition of Arcus iliopectineus

1. A thickened band of fused iliac and psoas fascia passing from the posterior aspect of the inguinal ligament anteriorly across the front of the femoral nerve to attach to the iliopectineal eminence of the hip bone posteriorly. The iliopectinal arch thus forms a septum which subdivides the space deep to the inguinal ligament into a lateral muscular lacunae and a medial vascular lacunae. When a psoas minor muscle is present, its tendon of insertion blends with the iliopectineal arch. Synonym: arcus iliopectineus, iliopectineal ligament, ligamentum iliopectineale. (05 Mar 2000)
