The intercrural fibers (intercolumnar fibers) are a series of curved tendinous fibers which arch across the lower part of the aponeurosis of the Obliquus externus describing curves with the convexities downward. They have received their name from stretching across between the two crura of the subcutaneous inguinal ring and they are much thicker and stronger at the inferior crus where they are connected to the inguinal ligament than superiorly where they are inserted into the linea alba.
