Definition[Bearbeiten]
The annulus inguinalis profundus is the inner opening of the inguinal canal located on the inside of the abdominal wall.
Anatomy[Bearbeiten]
The profundus inguinal canal has the shape of an oval with its longitudinal axis pointing upwards. It is bordered by the following structures:
- medially by the interfoveal ligament (reinforcement of the transversalis fascia)
- caudally by the inguinal ligament (inguinal ligament)
- cranially from the curved lower edge of the fascia of the transversus abdominis muscle.
The annulus inguinalis profundus lies lateral to the epigastric vessels (vasa epigastrica inferiora) in the fossa inguinalis lateralis.
In men, the spermatic cord passes through the profundus inguinalis anulus, in women the ligamentum teres uteri.
