Inguinal triangle

Inguinal triangle
Internal (from posterior to anterior) view of right inguinal area of the male pelvis. Inguinal triangle is labeled in green. The three surrounding structures: inferior epigastric vessels: Run from upper left to center. inguinal ligament: Runs from upper right to bottom left. rectus abdominis muscle: Runs from upper left to bottom left, labeled rectus at upper left.
External view. Inguinal triangle is labeled in green. Borders: inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center. inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom. rectus abdominis muscle: runs from upper left to bottom left.

In human anatomy, the inguinal triangle is a region of the abdominal wall. It is also known by the eponym Hesselbach's triangle, after Franz Kaspar Hesselbach.^[1]

Boundaries

It is defined by the following structures:^[2]

This can be remembered by the mnemonic RIP (Rectus sheath (lateral border), Inferior epigastric artery, Poupart's ligament (inguinal ligament)).

The inguinal triangle contains a depression referred to as the medial inguinal fossa, through which direct inguinal hernias protrude through the abdominal wall.^[3]
