Theintercrural fibers (intercolumnar fibers) are a series of curved tendinous fibers, which arch across the lower part of theaponeurosis of theObliquus externus, describing curves with the convexities downward.
They have received their name from stretching across between the two crura of thesubcutaneous inguinal ring, and they are much thicker and stronger at theinferior crus, where they are connected to theinguinal ligament, than superiorly, where they are inserted into thelinea alba.
The intercrural fibers increase the strength of the lower part of the aponeurosis, and prevent the divergence of the crura from one another; they are more strongly developed in themale than in thefemale.
As they pass across the subcutaneous inguinal ring, they are connected together by delicate fibrous tissue, forming afascia, called theintercrural fascia.
This intercrural fascia is continued down as a tubular prolongation around thespermatic cord andtestis, and encloses them in a sheath; hence it is also called theexternal spermatic fascia.
The subcutaneous inguinal ring is seen as a distinctaperture only after the intercrural fascia has been removed.
