In femoral hernias, the peritoneum and sometimes loops of intestine push into the area of the thigh through a weak spot in the tissue. About 5 to 10% of all hernias are femoral hernias.
The hernial orifice of a thigh hernia is always below the inguinal ligament. It is usually relatively small, which is why the hernia can easily become incarcerated. This is also favoured by the movement activity of the hip area.
If an incarceration (incarcerated hernia) occurs, it manifests itself as severe pain. Nausea and vomiting are further accompanying symptoms. Since the trapped organs are no longer supplied with blood, surgery must be performed immediately.
In 60% of cases, the thigh hernia occurs on the right side, in 20% on both sides.
Women are four times more likely to be affected by thigh fractures. It mostly affects overweight women over 50.
Pregnancy, obesity, collagen weakness, increasing age and diseases such as Marfan syndrome or Ehlers-Danlos syndrome increase the risk of femoral hernias. Moreover, femoral hernias often occur after weight loss.
In men, femoral hernias occur more often after inguinal hernia surgery. During the operation, the inguinal ligament is raised to repair the hernia. This promotes the formation of a hernia sac through the inguinal canal and the formation of a femoral hernia. In addition, however, a hernial orifice can also occur due to increased tension if the suture was closed too tightly after an operation.
The following symptoms can occur in connection with a femoral hernia:
