A direct hernia is characterized by its occurrence within Hesselbach's triangle, an anatomical region in the lower abdomen delineated by the inguinal ligament, the lateral border of the rectus abdominis muscle, and the inferior epigastric vessels. In this specific area, abdominal contents may protrude directly through the transversalis fascia, which is weaker than other layers of the abdominal wall.

Understanding Hesselbach's triangle is crucial for surgical technologists and surgeons, as it helps to identify the type of hernia and plan the appropriate surgical intervention. Direct hernias typically occur in older patients and are often associated with increased intra-abdominal pressure, leading to a bulge in the groin area.

Differentiating between types of hernias is important for effective diagnosis and treatment. Indirect hernias occur through the inguinal canal, while umbilical hernias happen at the umbilicus. Inguinal hernia is a broader term that encompasses both direct and indirect hernias, but it does not specifically refer to the location within Hesselbach’s triangle. Thus, identifying the precise nature of the hernia is essential, and in this case, a direct hernia is the correct classification.
