Inguinal Ligament, Superior View

Description

Oriented from a superior perspective, the inguinal ligament forms a dense fibrous band spanning from the anterior superior iliac spine laterally to the pubic tubercle medially, where its medial fibers reflect posteriorly to continue as the lacunar ligament along the pecten pubis. Deep to its length, the iliopsoas compartment lies posterolateral and the femoral vessels pass inferior to the ligament toward the femoral triangle, while the abdominal wall fascia and transversalis fascia contribute to the margins of the inguinal canal just superior to it. Medial to the canal, the pubic crest and superior pubic ramus provide bony landmarks for the ligament’s attachment and the adjacent pectineal (Cooper) ligament. This relationship matters because the inguinal ligament and lacunar ligament define the medial boundary of the femoral ring, the point where a femoral hernia enters before tracking into the femoral canal, often presenting inferolateral to the pubic tubercle. During open femoral hernia repair, division of the lacunar ligament can relieve strangulation, but the operator must respect the possible course of an aberrant obturator artery (corona mortis) along the superior pubic ramus. Small distances. Big consequences. Use this superior view to teach the boundaries of Hesselbach’s triangle versus the femoral ring in gross anatomy and surgical anatomy courses, or to support atlas plates and journal figures discussing hernia classification, mesh placement, and the relationship of fascia to the inguinal canal floor. It also suits patient education materials that need clear landmarking of the anterior superior iliac spine, pubic tubercle, and the medial reflection into the lacunar ligament.
