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",
Femoral sheath lymph gland and is covered by the parietal peritoneum. The septum femorale is pierced by numerous lymphatic vessels passing from the deep inguinal to the external iliac lymph glands, and the parietal peritoneum immediately above it presents a slight depression named the femoral fossa. Femoral sheath The femoral sheath (crural sheath) is formed by a prolongation downward, behind the inguinal ligament, of the abdominal fascia, the transverse fascia being continued down in front of the femoral vessels and the iliac fascia behind them. The femoral sheath is contained within the femoral triangle. The sheath assumes the form of a short
