Crural Ring, Femoral canal or ring. M. Jules Cloquet has described this canal with minuteness, and given it the name Anneau crural, Anneua femoral. It is nearly an inch long, triangular, more spacious above than below, and shorter and broader in the female than in the male. Its upper orifice is bounded, anteriorly, by the crural arch; posteriorly, by the crista of the pubis; on the outer side by the psoas and iliacus muscles, covered by the iliac aponeurosis, and, at the inner, by Gimbernats ligament. This orifice is covered by the peritoneum, and, according to M. Cloquet, is closed by a more or less resisting septum, which he has named Septum crurale, Crural septum. In its course, the crural canal has its anterior parietes formed by the superficial expansion of the fascia lata: the posterior by pectineus, covered by the deep-seated expansion of the fascia; and more externally by the psoas and iliacus muscles, covered by an expansion of the fascia; and more externally by the psoas and iliacus muscles, covered by an expansion of the fascia iliaca. Its inferior orifice is formed by the foramen of the fascia lata, which gives passage to the vena saphaena. It is at the upper orifice of this canal, that Femoral or Crural Hernia, Hernie inguinale of Chaussier, occurs: which would be more common, were it not for the fibrous cellular septum there situate.

Same as Femoral Canal.
