Conjoint tendon A weakening of the conjoint tendon can precipitate a direct inguinal hernia. A direct inguinal hernia will protrude through Hesselbach's triangle, whose borders are the rectus abdominis (medially), inferior epigastric artery and vein (superolaterally), and the inguinal ligament (inferiorly). The hernia will lie medial to the inferior epigastric artery. This is in contrast to an indirect inguinal hernia, which will protrude laterally to the inferior epigastric artery and is most commonly due to an embryological defect in the closure of the deep inguinal ring. Conjoint tendon The conjoint tendon (previously known as the inguinal aponeurotic falx) is a structure formed
Femoral artery Femoral artery The femoral artery is a large artery in the thigh and the main arterial supply to the leg. It enters the thigh from behind the inguinal ligament as the common femoral artery, a continuation of the external iliac artery. Injuries to the femoral artery can require reattachment surgery. Here, it lies midway between the anterior superior iliac spine and the symphysis pubis. The common femoral artery gives off the profunda femoris artery and becomes the superficial femoral artery to descend along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor
