A band running from the pubic tubercle to the anterior superior iliac spine. Its anatomy is very important for operating on hernia patients. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. The inguinal ligament runs from the anterior superior iliac spine of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. [ http://en.wikipedia.org/wiki/Inguinal_ligament ]
