Inguinal hernia men are 25 times more likely to have an inguinal hernia than women. Although several mechanisms such as strength of the posterior wall of the inguinal canal and shutter mechanisms compensating for raised intra-abdominal pressure prevent hernia formation in normal individuals, the exact importance of each factor is still under debate. The physiological school of thought thinks that the risk of hernia is due to a physiological difference between patients who suffer hernia and those who do not, namely the presence of aponeurotic extensions from the transversus abdominis aponeurotic arch. There are two types of inguinal hernia, "direct" and "indirect",
Body of pubic bone of the Obturator internus. Body of pubic bone The body of pubic bone forms the wide, strong, medial and flat portion of the pubic bone which unite in the pubic symphysis. The rough superior edge of the "corpus", the pubic crest, ends laterally in the pubic tubercle. This tubercle, found roughly 3 cm from the pubic symphysis, is a distinctive feature on the lower part of the abdominal wall; important when localizing the superficial inguinal ring and the femoral canal of the inguinal canal. Its "internal surface" enters into the formation of the wall of the lesser pelvis and gives
