Objective To re-understandthe structure of inferior area of myopectineal orifice to offer the anatomic evidence for prevention of femoral hernia after operation of acetabulum fracture via subilioinguinal approach. Methods Twenty human adult cadavers were dissected in the Anatomy Department at Xinxiang Medical College. The anatomical structures in the inferior area of myopectineal orifice includingfemoral sheath, lacunar ligament and pecten pubis fascia that may be exposed in the subilioinguinal approach were observed and documented. Results The shape of the inferior area of myopectineal orifice was similar to being ladder-shaped and the sealing structures included vagina vasorum, lacunar ligament and pectineus muscular fasciae. However, there were multiple domains in the inferior area of myopectineal orifice were weak enough to induce the femoral hernia. Conclusion The weak domains of the inferior area of the myopectineal orifice were the possible location for occurrence of femoral hernia, which required protection and/or reconstruction.
