[The fascia of the inguinal canal ring].

The fascial anatomy of the inguinal canal has been investigated. The spermatic cord is fixed by two cords in addition to its embedding in connective tissue after leaving the inguinal canal. The spermatic cord has a special fastening in form of a noose at the deep inguinal ring. The transversalis fascia consists of an internal and an external leaf. A part of the internal leaf forms with three cords this noose and builds so a sphincter-like closure mechanism, which reduces the size of the deep inguinal ring by a local erection of the transversalis fascia. The internal leaf protects from an indirect inguinal hernia as well as from a direct inguinal hernia, because the wall of the so-called Hesselbach's triangle only consists of the internal leaf. A list of the anatomical synonyms is added.
