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.
Structure
It is defined by the following structures:
- Medial border: Lateral margin of the rectus sheath.[1][2]
- Superolateral border: Inferior epigastric vessels.[1][2]
- Inferior border: Inguinal ligament.[1][2]
This can be remembered by the mnemonic RIP (Rectus sheath (medial), Inferior epigastric artery (lateral), Poupart's ligament (inguinal ligament, inferior).
Clinical significance
The inguinal triangle contains a depression referred to as the medial inguinal fossa, through which direct inguinal hernias protrude through the abdominal wall.[3]
History
The inguinal triangle is also known as Hesselbach's triangle, after Franz Kaspar Hesselbach.[2]
