Which of the following correctly describes the boundaries of Hesselbach's (inguinal) triangle, through which a direct inguinal hernia passes?

• A Inferior epigastric vessels medially, rectus abdominis laterally, conjoint tendon superiorly
• B Rectus abdominis medially, inferior epigastric vessels laterally, inguinal ligament inferiorly ✓
• C Lacunar ligament medially, femoral vein laterally, inguinal ligament anteriorly
• D Rectus abdominis medially, deep inguinal ring laterally, iliopubic tract inferiorly

Explanation

Hesselbach's triangle is bounded medially by the lateral border of the rectus abdominis, laterally by the inferior epigastric vessels, and inferiorly (base) by the inguinal ligament. Its floor is formed by the transversalis fascia, which is the weak layer giving way in a direct hernia. Option C describes the femoral canal boundaries, and option D mixes landmarks of the myopectineal orifice. Knowing that the inferior epigastric vessels form the lateral boundary is what separates direct from indirect hernia topographically.
