Obturator hernia

The abdominal organs protruding through the hip obturator tube from the femoral triangle are called obturator hernias. The obturator tube is a fibrous bone tube with a length of 2 to 3 cm, which runs obliquely forward, inward, and downward. The upper part of the tube is composed of the obturator sulcus above and below the pubic bone, and the lower part is formed by the connection of the pelvic sarcolemma and the obturator membrane covering the upper edge of the obturator inner muscle. The obturator membrane is a fibrous aponeurosis. The fibers are arranged in an irregular cross, divided into the outer membrane and the inner membrane. The inner mouth (pelvic cavity) is covered by the peritoneum and extraperitoneal tissue. The triangle formed by the pubic bone. Obturator nerves and obturator arteries and veins pass through the obturator canal to the inner thigh, so when there is a hernia prolapse, the obturator nerve is often compressed. The obturator artery comes from the internal iliac artery, but a small part of it comes from the artery of the lower abdominal wall. It passes through the edge of the pit ligament. When the inside of the inguinal ligament is cut accidentally, it is accidentally injured and difficult to control bleeding.
