Direct inguinal hernias protrude through which region?

• A. Hesselbach's triangle
• B. Deep inguinal ring
• C. Femoral canal
• D. Inguinal canal

Answer: (A)

Direct inguinal hernias arise from a weakness in the posterior wall of the inguinal canal and protrude specifically through Hesselbach's triangle. This small region is bordered medially by the rectus abdominis, laterally by the inferior epigastric vessels, and inferiorly by the inguinal ligament. Because the hernia passes medial to the inferior epigastric vessels, it emerges through this area in the abdominal wall, rather than through the deep inguinal ring. In contrast, indirect inguinal hernias go through the deep inguinal ring (lateral to the vessels), and femoral hernias go through the femoral canal. So the region involved is Hesselbach's triangle.
