A rare type of hernia of the pelvic floor in which pelvic or abdominal contents protrudes through the obturator foramen.
It is much more common in women, especially multiparous and older women who have recently lost a lot of weight.
The diagnosis is often made intraoperatively after presenting with bowel obstruction.
The Howship–Romberg sign suggested an obturator hernia, exacerbated by thigh extension, medial rotation and abduction.
It is characterized by sharp pain in the medial thigh/obturator distribution, extending to the knee.
The pain is caused by hernia compression of the obturator nerve.
