Hesselbach’s Triangle
Hesselbach’s triangle is an important anatomical structure. It is also known as medial inguinal fossa. It is located at anterior abdominal wall. As the name suggests, the Hesselbach’s triangle has 3 borders: 1. Medial border: made by lateral border of rectus abdominis muscle 2. Lateral border: demarcated by inferior epigastric vessels 3. Inferior border: made by inguinal ligament Hesselbach’s triangle is a relatively weak spot in the anterior abdominal wall. Hence, it is the location where herniation of abdominal contents can occur. The direct inguinal hernia occurs medial to the inferior epigastric vessels. In contrast, indirect hernia occurs at the lateral aspect of inferior epigastric vessels.
