Definition of Hasselbach's Triangle
- Hasselbach's triangle is an anatomical region in the groin area, described as the zone of weakness of direct inguinal hernia 1.
- It is bounded by the outline of Hesselbach's ligament, which separates the deep inguinal ring from the triangle 1.
- The triangle is an important landmark in the classification of inguinal hernia and is used as a reference point in laparoscopic repair of hernia 2, 3.
Anatomical Relations
- Hasselbach's triangle is located medially to the deep inguinal ring, which contains the testicular vessels and the vas deferens 1.
- The iliac psoas muscle passes laterally underneath the inguinal ligament, while the external iliac vessels are located medially 1.
- The pectineal ligament lies on the posterior surface of the femoral ring, between the umbilical artery and the epigastric artery 1.
Clinical Significance
- Hasselbach's triangle is a common site for direct inguinal hernias, and its anatomy is important for surgeons to understand in order to perform successful hernia repairs 1, 4.
- Anatomical changes in the groin area, including changes in the size and shape of Hasselbach's triangle, can occur after inguinal hernia treatment and may contribute to chronic pain and hernia recurrence 4.
- The relationship between anthropometric parameters and measurements of the human inguinal region, including Hasselbach's triangle, has been studied, but the results have shown little correlation 5.
