[edit] Discussion

  • The obturator foramen is formed by the continuity of the pubic and ischial bones.
  • It is covered by the obturator membrane except in its anterior-superior aspect, where it is perforated by the obturator artery, vein, and nerve.
  • The neurovascular bundle then travels along a 2- to 3-cm oblique tunnel formed by the internal and external obturator muscles, the so-called obturator canal.
  • It has been suggested that the female predominance of these hernias is the result of pregnancy, which leads to relaxation of the pelvic peritoneum and a widen and more horizontal obturator canal.
