Hip Bone Showing The Iliopubic Eminence, Medial View

Description

Iliopubic (iliopectineal) eminence rises at the junction of the ilium and pubis along the pelvic brim, forming a palpable bony ridge on the superior pubic ramus. Medial to this prominence, the pubic body continues toward the symphyseal surface, while inferiorly the superior ramus slopes toward the obturator foramen, framing the obturator groove and canal. Superior and lateral to the eminence, the iliac fossa occupies the pelvic surface of the ilium, and posteriorly the arcuate line tracks toward the auricular surface and the greater sciatic notch. Bony contours are presented without overlying soft tissue, keeping the relationship between the pecten pubis (pectineal line) and the pelvic inlet easy to read. The iliopubic eminence matters because it is a fixed landmark for the iliopectineal line, the anterior column reference used in acetabular fracture classification and preoperative planning, and it sits immediately adjacent to sites where plates and screws are contoured during pelvic brim fixation. It is also the anterior anchor region for Cooper’s (pectineal) ligament along the pecten pubis, a target in laparoscopic and open repairs of femoral and inguinal hernias where the femoral canal lies just lateral to the pubic tubercle. A hard landmark. Use this illustration in gross anatomy and radiologic anatomy teaching when introducing the pelvic brim, the superior pubic ramus, and the transitions between the ilium and pubis, or in orthopaedic and general surgery texts that explain iliopectineal approaches, hernia repair fixation points, and pelvic ring hardware positioning.
