Femoral hernias are hernias which occur just below the inguinal ligament, when abdominal contents pass through a naturally occurring weakness in the abdominal wall called the femoral canal. Femoral hernias are a relatively uncommon type, accounting for only 3% of all hernias. While femoral hernias can occur in both males and females, almost all ...
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 ...
Inguinal hernias, in turn, belong to groin hernias, which also includes femoral hernias. A femoral hernia is not via the inguinal canal, but via the femoral canal, which normally allows passage of the common femoral artery and vein from the pelvis to the leg. In Amyand's hernia, the content of the hernial sac is the appendix.
Obturator artery. The relations of the femoral and abdominal inguinal rings, seen from within the abdomen. Right side. (Obturator artery is visible at bottom.) Internal iliac artery and some branches. The obturator artery is a branch of the internal iliac artery that passes antero-inferiorly (forwards and downwards) on the lateral wall of the ...
Anterolateral view of the right side of the pelvis. The inguinal ligament (/ ˈɪŋɡwɪnəl / [1][2]), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.
The femoral sheath (also called the crural sheath) is a funnel-shaped downward extension of abdominal fascia within which the femoral artery and femoral vein pass between the abdomen and the thigh. The femoral sheath is subdivided by two vertical partitions to form three compartments (medial, intermediate, and lateral); the medial compartment ...
The entrance to the femoral canal, the femoral ring, is labeled at right. The femoral canal is the medial (and smallest) compartment of the three compartments of the femoral sheath. It is conical in shape. The femoral canal contains lymphatic vessels, and adipose and loose connective tissue, as well as - sometimes - a deep inguinal lymph node.
The lacunar ligament is the part of the aponeurosis of the external oblique muscle that is reflected backward and laterally and is attached to the pectineal line of the pubis. It is about 1.25 cm. long, larger in the male than in the female, almost horizontal in direction in the erect posture, and of a triangular form with the base directed ...
