Medial inguinal fossa
The medial inguinal fossa (Latin for ' inguinal cavity located in the middle') is a muscle-free part of the abdominal wall opposite the outer inguinal ring ( superficial inguinal annulus ) . It lies on the inside of the abdominal wall between the plica umbilicalis medialis (' umbilical fold located in the middle', contains the obliterated umbilical artery ) and the plica umbilicalis lateralis ('lateral umbilical fold', contains the arteria and vena epigastrica inferior ). At this point the abdominal wall is only formed by the transversalis fascia and the peritoneum .
The medial inguinal fossa is the weakest point of the anterior abdominal wall and is therefore a common location for an inguinal hernia . The medial inguinal fossa represents the inner hernial port of a direct inguinal hernia. On the one hand, no abdominal muscles are developed here; on the other hand, the external aponeurosis of the external oblique abdominis muscle has a gap due to the division into two legs ( lateral and medial crus ). the outer inguinal ring. The Hesselbach triangle lies within the medial inguinal fossa .
