A sports hernia occurs when there is a weakening of the muscles or tendons of the lower abdominal wall. This part of the abdomen is the same region where an inguinal hernia occurs, called the inguinal canal. When an inguinal hernia occurs there is sufficient weakening of the abdominal wall to allow a pouch, the hernia, to be felt. In the case of a sports hernia, the problem is due to a weakening in the same abdominal wall muscles, but there is no palpable hernia.
What is the inguinal canal?
The inguinal canal is a region in the lower abdomen, just above the groin. The canal is formed by the insertions of abdominal muscles and tendons, as well as several ligaments. Within the inguinal canal travels the spermatic cord (in males) or the round ligament (in females). This area of the abdomen is prone to weakening of the abdominal wall, allowing an outpouching, or hernia, to form.
I have strong abdominal muscles, how can I have a sports hernia?
The problem with the abdominal wall in people with a sports hernia is not a muscle strength issue. Rather, the abdominal wall in a particular region is too thin, allowing the hernia to form. The sports hernia does not occur in the area of the large, thick part of the muscle.
What are the symptoms of a sports hernia?
A sports hernia typically begins with a slow onset of aching pain in the lower abdominal region. Symptoms may include:
Typically the symptoms are exacerbated with activities such as running, cutting, and bending forward. Patients may also have increased symptoms when coughing or sneezing. Sports hernias are most common in athletes that have to maintain a bent forward position, such as hockey players. However, sports hernias are also found in many other types of athletes such as football and soccer players.
