An obturator hernia is a rare type of hernia, encompassing 0.07-1% of all hernias,[2] of the pelvic floor in which pelvic or abdominal contents protrudes through the obturator foramen. The obturator foramen is formed by a branch of the ischial (lower and back hip bone) as well as the pubic bone. The canal is typically 2-3 centimeters long and 1 centimeters wide, creating a space for pouches of pre-peritoneal fat.
