What is the significance of Hesselbach triangle?
The Hesselbach triangle, also called the inguinal triangle, is a region of the lower anterior abdominal wall. If weakened, the Hesselbach triangle can allow for the protrusion of the intestines through the wall, known as a direct inguinal hernia.
What is the inguinal triangle made of?
It is defined by the following structures: Medial border: Lateral margin of the rectus sheath. Superolateral border: Inferior epigastric vessels. Inferior border: Inguinal ligament.
How can you tell the difference between a direct and indirect inguinal hernia?
A direct inguinal hernia shows a bulge from the posterior wall of the inguinal canal, whereas an indirect inguinal hernia passes through the inguinal canal or the groin. In the indirect inguinal canal, it is difficult to feel the defect as it occurs behind the external oblique muscle fibers.
Does direct hernia pass through superficial ring?
Indirect inguinal hernias pass through the deep inguinal ring, down through the canal toward the superficial ring. Direct hernias are acquired and pass through a weakened abdominal wall medial and inferior to the deep ring.
Why are inguinal canals larger in males?
Deep inguinal ring It is an oval defect in the transversalis fascia, which is widest along the vertical axis of the opening. The defect is significantly larger in males than in females, as it is meant to accommodate the passage of the testes into the scrotal sac.
What forms the inferior border of the inguinal triangle?
inguinal ligamentIt has the following boundaries: Medial – lateral border of the rectus abdominis muscle. Lateral – inferior epigastric vessels. Inferior – inguinal ligament.

Bulges through the abdominal wall and actually goes into the scrotum so it sort of follows the spermatic cord.
Why inguinal hernia is common on right side?
Inguinal hernia is the most frequent problem requiring elective surgical intervention in children. Because of later descent of right testis and subsequently delayed obliteration of right processus vaginalis, inguinal hernia presents more frequently on the right side.
Can you have a inguinal hernia without a bulge?
A sports hernia does not cause a visible bulge in the groin, like the more common inguinal hernia does. Over time, a sports hernia may lead to an inguinal hernia, and abdominal organs may press against the weakened soft tissues to form a visible bulge.
What is a triangle hernia?
Definition. A Lumbar hernia is a protrusion through the lumbar triangle. There are two lumbar triangles, which lie between the bottom of the 12th (last) rib and the hipbone and are situated around the back of the body. It is seen as a hernia on the side of the abdomen.
Why is direct hernia called direct?
This type of hernia is termed direct as the hernial sac directly protrudes through the inguinal wall, in contrast to indirect inguinal herniae which arise through the deep ring and enter the inguinal canal.
What passes through the deep inguinal ring?
The genitofemoral nerve is derived from the L1-L2 spinal nerve roots. It divided above the inguinal canal to the genital branch that passes through the deep inguinal ring with the cord structures, and the femoral branch that passes below the inguinal canal.
What are the contents of the inguinal canal?
The contents of the inguinal canal in males consist of the spermatic cord (with the genital branch of the genitofemoral nerve) and the ilioinguinal nerve. For females, the contents include the round ligament, genital branch of the genitofemoral nerve, and the ilioinguinal nerve.
What is the inguinal ring?
The superficial or external ring is the terminal end of the inguinal canal. It is located just superior to the pubic tubercle. The superficial ring has a triangular shape that is made by fibers of the external oblique muscle. These fibers continue to cover the inguinal contents as they descend into the scrotal area.

What is the inguinal triangle?
The Inguinal (Hesselbach’s) Triangle. The inguinal triangle ( Hesselbach’s triangle) is a region in the anterior abdominal wall. It is alternatively known as the medial inguinal fossa. It was first described by Frank Hesselbach, a German surgeon and anatomist, in 1806.
Where is the inguinal triangle located?
Log In. The inguinal triangle ( Hesselbach's triangle) is a region in the anterior abdominal wall. It is alternatively known as the medial inguinal fossa. It was first described by Frank Hesselbach, a German surgeon and anatomist, in 1806.
Does the inguinal triangle demarcate weakness?
However, the triangle does demarcate an area of potential weakness in the abdominal wall – through which herniation of the abdominal contents can occur. By TeachMeSeries Ltd (2021) Fig 1 – The borders of the inguinal triangle.
What is the Hesselbach triangle?
The Hesselbach triangle, also called the inguinal triangle, is a region of the lower, anterior abdominal wall, or groin , that was first described by Frank Hesselbach, a German surgeon and anatomist, in 1806. It describes a potential area of weakness in the abdominal wall, through which a hernia can protrude. A hernia is defined as a protrusion of an organ or fascia, a thin sheath of tissue that encloses a muscle or organ, through the wall that usually contains it. A hernia of the anterior abdominal wall is typically a protrusion of the intestines.
What are the most important facts to know about the Hesselbach triangle?
If weakened, the Hesselbach triangle can allow for the protrusion of the intestines through the wall, known as a direct inguinal hernia. This region is bound by the inguinal ligament, inferior epigastric vessel, and rectus abdominis muscle. While a direct inguinal hernia protrudes through a weakness in the muscle of Hesselbach’s triangle, an indirect inguinal hernia does not. Additionally, an indirect inguinal hernia will protrude through both the superficial and deep inguinal ring, whereas the direct inguinal hernia will only protrude through the superficial inguinal ring.
Where is the Hesselbach triangle located?
The Hesselbach triangle is located in the anterior abdominal wall bilaterally (on both the right and left sides) and has three major boundaries: the medial boundary consisting of the rectus abdominis muscle; the lateral boundary consisting of the inferior epigastric vessels, which supply the anterior abdominal wall with blood; and the inferior boundary consisting of the inguinal ligament, a narrow band of tissue in the pelvic region of the body.
Where is the inguinal triangle located?
The location of the the inguinal triangle is found deep to the posterior wall of the inguinal canal. This is why the inguinal triangle is observed on the inner aspect of the lower part of the anterior abdominal wall.
What is the neck of a hernial sac?
The neck of hernial sac is wide. The direct inguinal hernias are typical in aged because of poor abdominal muscles. The direct hernia leaves the triangle via its lateral part or medial part, and consequently it’s of 2 types: (a) lateral direct inguinal hernia, and (b) medial direct inguinal hernia.
