Try to know the various approaches to fixing a femoral hernia, and be aware of the different scenarios regarding femoral hernias, like when to use mesh versus primary repair, depending on the viability of the hernia contents. Know what complications can occur during a laparoscopic hernia repair. Tacks put out laterally can damage the lateral femoral cutaneous nerve. Tacks placed on the inferior aspect of the Cooper ligament can potentially injure the corona mortis. The historical hernia repairs are still important know. +++ ANATOMY +++ What are the 9 layers of the abdominal wall? ++ Skin, subcutaneous tissue, superficial fascia, external oblique muscle, internal oblique muscle, transversus abdominis muscle, transversalis fascia, preperitoneal adipose and areolar tissue, and peritoneum +++ What is the portion of the external oblique aponeurosis that extends from the anterosuperior iliac spine to the pubic tubercle called? ++ Inguinal (Poupart) ligament ++ FIGURE 13-1 Cross-sectional anatomy of the abdominal wall above and below the arcuate line of Douglas. The lower right abdominal wall segment shows clearly the absence of an aponeurotic covering of the posterior aspect of the rectus abdominis muscle inferior to the arcuate line. Superior to the arcuate line, there are both internal oblique and transversus abdominis aponeurotic contributions to the posterior rectus sheath. (Reproduced with permission from Moore KL, Dalley AF.
