We learned in Anatomy that the prepublic tendon is essentially the tendon of insertion of the two recti adbominis, but also furnishes attachment to the obliqui, the graciles, and the pectinei. It is attached to the anterior borders of the pelvic bones, including the iliopectineal eminence. It has the form of a very strong, thick band, with concave lateral borders which form the medial boundaries of the subcutaneous inguinal rings. Occasionally the prepubic tendon will rupture, resulting in a downward displacement of the abdominal viscera, with a backward displacement of the pubis.
