Epidemiology

Age

• Most common in older women.
• Commonly called as 'Little old lady's hernia'.

Gender

• More common in females due to
  • wider pelvis
  • more triangular obturator canal opening
  • greater transverse diameter.
• Usually occurs in elderly and multiparous women.

Other

• Obturator hernia can also be seen in conditions with chronically raised intra abdominal pressure like ascites, COPD, chronic cough.
• Can be seen in pregnant women due to relaxation of pelvic peritoneum, and a wider and more horizontal obturator canal.
