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]
