What is the defining feature of an incisional hernia?

It occurs at the site of a previous surgical wound
It never reduces
It is always associated with inguinal hernias
It presents only in female patients

The correct answer is: It occurs at the site of a previous surgical wound

An incisional hernia is specifically characterized by its occurrence at the site of a previous surgical incision. When the abdominal wall is incised for surgery, the layers of the abdominal wall can weaken as they heal. This weakness can lead to the development of a hernia where the abdominal contents protrude through this weakened area. This feature distinguishes incisional hernias from other types of hernias that may occur in different anatomical locations or due to different causes. The notion that incisional hernias never reduce is inaccurate since many of them can be manually pushed back into the abdomen, especially if they are of a small size. The idea that incisional hernias are always associated with inguinal hernias does not hold true, as these two types of hernias can occur independently of one another. Additionally, the statement regarding the gender specificity of incisional hernias is incorrect; they can occur in both males and females, regardless of prior surgical history.
