The femoral sheath is made by extensions, the transversal is fascia anteriorly, and the iliac fascia posteriorly. It begins at the inguinal ligament. Within the femoral sheath is the femoral artery, femoral vein, and femoral canal. Each separated by these septi or partitions. Let's consider the femoral canal in isolation for a moment. It's a conical structure, a bit over a centimetre long. It contains a bit of lymph vessel, is said to contain just one lymph node, and there's also some connective tissue in there as well. It may sound small and insignificant, but is clinically relevant as the site of femoral hernia. The entrance to the canal, the open portion up top, is called the femoral ring. We can remember its boundaries with the mnemonic slip. Lateral we've got the medial septa of the femoral sheath. Medial we have the lacuna ligament, anterior the inguinal ligament, and posterior lying flush with the pubic bone. We have the pectinial ligament. These are particularly inflexible ligaments, which is a worry for us because if small bowel moves into the canal in the setting of a femoral hernia, there's a high risk of strangulation. With enough pressure behind it, a femoral hernia will forge its way down the canal and then push out the saffonus opening, which is a hole in the fascia lata. This isn't a particularly forgiving ring either, so we now have two places at which tight borders may cut off blood supply to this herniated organ, leaving us with an ischemic piece of bowel lurking underneath the skin. Femoral hernias are uncommon and mainly occur in female anatomy due to the wider shape of the pelvis. And we're going to leave it there for now. Thanks for watching, and we'll see you next time.
