462:, whether the hernia is reducible, incarcerated or strangulated. When the obturator artery travels along the lacunar ligament, it nearly encircles the femoral ring and can be lacerated during a femoral hernia repair. Most femoral hernias are repaired through a small (1/2 to 3/4 inch) incision in the groin area, rather than through the abdomen, so if a laceration were to occur, bleeding may not be immediately recognized and result in significant blood loss into the peritoneal cavity. Because of this danger, the anatomic variant in Figure B is sometimes referred to as the "crown of death" (corona mortis).
440:. In studies, it has been found that corona mortis is in half of all hemipelvis with a prevalence of 46%. In other studies, it is found to be 33.33% in both hemipelves of the individuals. The variation has also been found to be more common in patients from Europe than in Asia where studies have been conducted. In comparative studies, it was found that European patients had a 10% higher chance of having the arterial variation when compared to Asian population. The artery in this course usually lies in contact with the

The blood supply to the femoral head and neck is enhanced by the artery of the ligamentum teres derived from the obturator artery. In adults, this is small and doesn't have much importance, but in children whose epiphyseal line is still made of cartilage (which doesn't allow blood supply through it),

The articular branch is usually patent until roughly 15 years of age. In adults it does not provide enough blood supply to prevent avascular necrosis in upper femur fractures.
