What: The inguinal triangle, also called Hesselbach’s Triangle after Franz Caspar Hesselbach who first described the region, is a triangular region of potential weakness located on the inferoanterior (lower front) abdominal wall.


Importance: The inguinal triangle is used to define inguinal hernias, as the triangle contains the medial inguinal fossa, a depression through which inguinal hernias bulge through the abdominal wall.


Location: its medial border is formed the Rectus abdominis; the lateral border by the Inferior epigastric vessels; and the inferior border by the inguinal ligament (also called the Poupart’s ligament). The borders can easily be remembered using the mnemonic RIP.


Contents: Structures that lay within the triangle include the Lacunar and Cooper’s ligaments as well as the Ductus deferens.
